Validação de um método auxiliar de diagnóstico como preditivo da presença de cárie de dentina em dentes decíduos

Esse estudo se propôs a avaliar um método auxiliar de diagnóstico (DIAGNOdent®) na predição de cárie de dentina em dentes decíduos, através de validação histológica e de microdureza. Verificando possíveis diferenças entre os valores obtidos através do método auxiliar, além de determinar um ponto de corte para parada de remoção de tecido cariado. A amostra do estudo foi de 15 crianças que apresentaram 21 cavidades de cárie, tratadas e analisadas desde antes da realização da restauração até quando da exodontia do elemento dentário. Os espécimes foram analisados através do DIAGNOdent® antes da abertura das cavidades, após a remoção do tecido cariado e depois da reabertura das cavidades que se deu após a exodontia dos elementos dentários. Posteriormente, receberam preparo metalográfico para realização de testes de microdureza e microscopia óptica que serviram como forma de validação para as mensurações obtidas pela fluorescência a laser. Houve diferença significativa entre os valores DIAGNOdent® encontrados antes da abertura da cavidade e os demais (p < 0,0001). Havendo correlação significativa (r = 0,432 ; p = 0,019) apenas para as aferições obtidas antes da abertura das cavidades e quando do término da remoção do tecido cariado. Para a microdureza, as médias axiais foram significativamente maiores que as pulpares, existindo correlação entre a microdureza pulpar e os valores do DIAGNOdent® após a reabertura (r = - 0,472 ; p = 0,002). Valores de 15,38% para a sensibilidade, 100% para a especificidade, 100% para o valor preditivo positivo e 71,79% para o valor preditivo negativo, foram obtidos quando se utilizou um ponto de corte de 30 para fluorescência a laser, tendo como padrão-ouro a microdureza pulpar. Partindo da média dos valores de fluorescência a laser obtidos após a remoção do tecido cariado e acrescentando-se um desvio-padrão a esta, o método indicou o valor de 19 como ponto de corte para cessar a remoção de dentina. Concluiu-se que, nas condições analisadas, o método auxiliar de diagnóstico (DIAGNOdent®) é um método acurado na predição de cárie de dentina em dentes decíduos. Além disso, o método comprovou que o padrão usual de remoção de dentina garante a remoção do tecido cariado

A documentação odontológica sob a ótica dos cirurgiões-dentistas de Natal-RN

The dental documentation or handbook is a collection of documents produced by the professional with diagnostic and therapeutical purpose where the inherent information to the buccal and general health of patients are registered. The register and proper filling of these documents, taking care of the ethical and legal requirements, provide to the dentist the possibility to contribute with justice in cases of human identification and makes of these documents an essential element of evidence in the ethical processes, administrative, civil and criminal against the dentists. Ahead of this fact, understanding such requirements and the importance of the dentist to register himself adequately, this research verified the knowledge of Natal (RN) City s dentists with relation to the elaboration of the dental handbook, investigating the concepts and the importance attributed to the handbook, identifying the documents more used and filed by these professionals, besides inquiring the legal value of filed documents and the filling time of these ones. The sample was constituted by 124 dentists, who had answered a questionnaire, after having been randomly selected ITom a list of professionals subscribed in the Dentistry Local Council/RN Section. The analysis of the results showed that majority of the participant citÍzens (52,3%) confers to the dental documentation the clinical importance, followed by the legal and forensic-dentistry importance; 59,3% of the searched professionals do not distinguish satisfactorily or they do not observe differences between the dental handbook and the clinical filing card, the X-rays, the dental certificates, the prescriptions, the directions and the receipts; between the documents of common use to clínical and specialist ones, the contract of rendering of services and term of ITee and cleared up consent are the documents less used by the professionals. It was still verified, that only 13,1% of the sample register the signature of the patients in the clinical filing card, making it more credibility to be presented in judgement. In the same way, copies of dental certificates and prescriptions evaluated and signed by the patients are filed respectively by only 13,5% and 9,4% ofthe searched professionals and 50% ofthe sample, keep these documents filed for an indeterminate period of time, that is, these professionals have the guard of the handbook and they do not intend to disdain it, although 85,5% of the sample does not recognize the real proprietor of the handbook. It is concluded that a great part of the dentists is unaware about the importance of the dental documentation, and neglect its elaboration, leaving themselves exposed to several kinds of penalties foreseen in the legislation

A Perda Auditiva Induzida pelo Ruído (PAIR) na formação odontológica: conhecimentos e níveis de exposição

The rationalization of work in the Dentistry has been taking the professional to work for ways and systems based in the ergonomics, turning their work efficient and less tiring. Since their academic formation, the dentists surgeons are concerned with the high productivity in clinic and with the final result of the work, neglecting the way as it is executed, which reduce their work capacity and exhibits them to occupational diseases that could be minimized and/or forewarned. This research had as the main objective to investigate the knowledge of the Dentistry academics of Rio Grande do Norte Federal University concerning the Noise-induced Hearing Loss (NIHL), relating them at the noise levels that they are exposed, as well as to the preventive measures taken during the clinical activities. Was observed that 95% of the individuals know that the dentist surgeon is a professional in risk for NIHL. Among the causes of NIHL, the one that obtained the largest frequency citation was the high-speed handpieces, reminded by 92,4% of the academics. Among the students which enumerated protective measures for NIHL, 92% mentioned the use of the ear plugs, although 97% of the researched have told do not use any kind of preventive measure related to the noise. Was also observed that 96% of the academics notice the noise during the clinical attendance, what inconvenience 28,1% of them. Related the noise levels, the high-speed handpieces of the academics presented a medium value of 80,5 dB varying from 72,3 to 88,3 dB. The average of the ambient noise observed at the Integrated Clinic was about 74,8 dB. In spite of the noise levels in this research were observed below the established limits of tolerance by the legislation, they can provoke damages to the Dentistry professionals' health, or that suggests the need of an intervention and use of immediate preventive measures able to generate a healthy atmosphere of work and less risky

Avaliação em saúde bucal na perspectiva do usuário: enfoque ao estudo da acessibilidade organizacional

Due to the fact of oral health sector reestructuration within Brazilian public health politics, this work had the object of evaluating, under users point of view, the accessibility to oral health services in Santa Cruz (RN), focusing on the organizational aspect. To achieve this, questionnaires were given to users in their homes, considering the censitary sector. Nine sectors of the urban zone were evaluated, selected by chance, and one from the rural zone, selected by convenience. The sample was composed by 194 users, calculated considering the estimated prevalence of event represented by the indicator I ve never been to the dentist + I ve been to the dentist more than three years ago from the Projeto SB Brasil Report . To complement the results, interviews were made with others actors involved in the process of oral health care: professionals (dentists) and manager (Health Municipal Secretary). From the data obtained it was possible to identify that 12,9% of the population had never visited the dentist, and that the search for the service was not influenced by the users individual and socioeconomics characteristics, excepting the gender. It was verified that 36,1% of the users went to the dentist in less than one year, with the youngests (p<0,05) being among those who went to the dentist more frequently. 63,3% of the interviewed related that they found some kind of difficulty when they search for dentistry services, with the difficulties for schedule, the queues and the long wait among the most cited. It was identified that 43,2% of the users wait three weeks or more for the appointment. It is still pointed out that 71,4% of the interviewed find difficulties to get urgency appointment, the long wait to be attended by the dentist was the most found. 92,9% and 94,1% of the interviewed had never been headed to especialized appointments and complementary exams, respectively. Due to the data founded, it was possible to verify that the accessibility to oral health services in Santa Cruz (RN) is damaged by factors related to the organization of public polices developed, mainly in relation to the working process

Avaliação da saúde bucal na atenção básica: a perspectiva do usuário

Nowadays, the basic attention in health works according to the Health Family Program (HFP), which is responsible for the organization of the health services with view to provide an appropriate attendance to the needs of the population. Its expansion is expressive in whole country and, the oral health, included in this process, has been seen as a possibility of change the health practices centered in the disease. In face of this perspective, the proposal of study is to discover possible changes in the health care model of oral health in a district, made possible through the perception, evaluation and degree of satisfaction of the user s health service. To reach such objectives, the district of Macaíba in the State of Rio Grande do Norte, was chosen for operational subjects, such as time of implantation of HFP and great covering of this program. The current research used interviews structured with objectives and subjectives questions and questionnaires of socioeconomic characterization addressed to two hundred and seventy (270) individuals (ninety users of an Urban PSF, ninety of a Rural PSF and ninety of an unit non PSF). The analysis of the data was accomplished through the software SPSS/99, that made possible a statistical and analytic appreciation. The HFP units and non HFP units has shown to sort the common odontology problems of the community, and this didn't establish a direct relationship with the general satisfaction. On the other hands, the programmed consultation is related with lager satisfaction of the users. The access form to the odontology treatment of the Units, the satisfaction with the attendance rendered by the dentist and the equip, enough dentists for the community and the social class of the user were decisive for the general satisfaction with the service of oral health. On the other hand, variables as age and education, resolution of the problem and physical conditions of the unit didn't influence the general satisfaction. In spite of the progresses in the implantation of the oral health in ESF, preventive activities, visits at home, access and social participation still reproduce the traditional model of attendance, showing a primary change process

Influência de fatores de risco na prevalência de hábitos bucais deletérios em crianças de 0 a 5 anos na cidade do Natal-RN

Literature has demonstrated to the narrow relation between deleterious habits and the occurrence of malocclusion in minors of 5 years. The existence of these habits, however, already considered as risk factors, having also, its determinative ones, which present cultural dimensions and economic social, many of them related to the parents of the child, having in account that such habits if develop in phases in which the child establish a narrow relation of dependence. This study it had an objective to investigate the prevalence of deleterious buccal habits in children and its relation with the economic social and characteristics of the parents. It was developed an epidemiologist study of transversal character with interview, through daily pay-tested form, with 218 parents in the day of the National Campaign of Vaccination. In the cast of the variable that had composed the study, they had been used, as changeable dependents, the use of the baby's bottle, bottle and the digital suction, being considered as outcomes of the research. Amongst the independent variable, the economic social factors (type of occupation, number of children, civil state, sort, schooling and age) and staffs of the parents (self perception in oral health) had entered as the variable to be analyzed in the problems of the infantile odontology. The collected data had been submitted to the analysis descriptive and inferential statistics, being used the test qui-square and the analysis of the possibility reasons. As main results, it was found that breast feeding before the six months if presents as one of the main factors of risk for the use of baby's bottle (p< 0.001, OR= 2.8, I.C= 1.589 4.906), bottle (p< 0.001, OR= 3.7, I.C.= 2.076 6.624) and digital suction (p< 0.014, OR= 3.5, I.C.= 1.225 10.181). From the data found, one concludes that breast-feeding is considered a primordial factor for not the installation of deleterious oral habits and that the economic social and cultural factors can reflect in central way in the performance of this act

Relação entre a doença periodontal e doença cardiovascular: há uma preocupação por parte dos que fazem clínica médica e odontológica na cidade de Natal?

The relationship between periodontal and cardiovascular diseases is a reality in the current days. The knowledge about the role of periodontal disease as a risk factor to cardiovascular disease from dentistry and physicians is very important to try to eliminate this risk factor. The aim of this work was to investigate, using a questionary, if physicians and dentistry are aware about this relationship and if they think that it is important. These forms were distributed in 4 groups: cardiologists (n=90), physicians from other specialist (POS) (n=110), periodontists (n=35) and dentistry from other specialist (DOE) (n=85). We had a loss off 32,4% of the total sample due to a lack of response of some professionals. Our results showed that all cardiologists, all dentists and 68,2% of POE said that they had gotten information about the relationship between periodontal and cardiovascular disease, and just 6 POS don t believe that this relationship can occur. When questioned if, even when a periodontal disease is diagnosed, there is a habit to treat or orient the patient for treatment, 29,5% of cardiologists answered no, 25,5% of POE also answered that they did not orient and only 1 DOE answered that he did not treat nor orient. All periodontists said that treat their patients when periodontal disease was identify. The physicians seem not to find important the relationship that exist between periodontal and cardiovascular diseases and the dentistry have shown a good knowledge about this subject. Maybe, if physicians and dentistry work together, the incidence of cardiovascular disease decreases

Eficácia do cimento de ionômero de vidro como selante oclusal sobre a paralisação de lesões cariosas em dentina

Dental caries consists in a multifactorial and dynamic process. The knowledge of the ionic interactions among dental tissues and dental biofilm make possible its understanding as a process that can be stopped. Recently, the use of sealants have lost its function as preventive agent and passed to be argued as a possible therapeutical agent. This happens by hindering the substratum flow to the lesion inner and, therefore, controls the advance of the process. This study aimed to evaluate glass ionomer cement as a not invasive technique of treatment in occlusal caries without clinical cavitation, but with dentinal involvement. The research was accomplished using a controlled clinical trial with two groups (experimental and control) in 38 subjects (8-18 years) with 51 molars. The teeth of the experimental group were sealed with glass ionomer cement (Vidrion-R, S.S.White, Juiz de Fora, Brazil) and the molars control did not suffer intervention. The experimental group was followed by a year and the control by 8 months due the progression of the carious injury. Both groups were reevaluated to each 4 months with the use of clinical, radiographic and laser fluorescence (DIAGNOdent®) examination. The analysis of the clinical evaluation did not observe a significant difference between experimental and control groups. However, analysis with radiographic and laser fluorescence (DIAGNOdent®) examination observed a significant difference (p> 0,05) between groups, demonstrating a wors condition to the group without intervention. The results suggest that glass ionomer cement as sealant can be efficient to paralyze dentinal caries without clinical cavitation

Prevalência e susceptibilidade antimicrobiana de Staphylococcusspp. em quadros de saúde e doença periodontal

The aim of this study was determine the prevalence and antimicrobial susceptibility of Staphylococcus spp. from patients with periodontal disease and periodontally healthy, correlate them with factors to host, local environment and traits of the diseases. To this, thirty adults from 19 to 55 years old were selected. They had not periodontal treatment and no antibiotic or antimicrobial was administered during three previous months. From these individuals, sites periodontally healthy, with chronic gingivitis and/or periodontitis were analyzed. Eighteen subgingival dental biofilm samples were collected through sterile paper points being six from each tooth randomly selected, representing conditions mentioned. They were transported to Oral Microbiology laboratory, plated onto Mannitol Salt Agar (MSA) and incubated at 370C in air for 48 h. Staphylococcus spp. were identified by colonial morphology, Gram stain, catalase reaction, susceptibility to bacitracin and coagulase activity. After identification, strains were submitted to the antibiotic susceptibility test with 12 antimicrobials, based on Kirby-Bauer technique. To establish the relation between coagulase-negative Staphylococcus (CSN) presence and their infection levels and host factors, local environment and traits of diseases were used Chi-square, Mann-Whitney and Kruskal-Wallis tests to a confidence level of 95%. 86,7% subjects harbored CSN in 11,7% periodontal sites. These prevalence were 12,1% in healthy sites, 11,7% in chronic gingivitis, 13,5% in slight chronic periodontitis, 6,75% in moderate chronic periodontitis and in sites with advance chronic periodontitis was not isolated CSN, without difference among them (p = 0,672). There was no significant difference to presence and infection levels of CSN as related to host factors, local environm ent and traits of the diseases. Amongst the 74 samples of CSN isolated, the biggest resistance was observed to penicillin (55,4%), erythromycin (32,4%), tetracycline (12,16%) and clindamycin (9,4%). 5,3% of the isolates were resistant to oxacilin and methicillin. No resistance was observed to ciprofloxacin, rifampicin and vancomycin. It was concluded that staphylococci are found in low numbers in healthy or sick periodontal sites in a similar ratio. However, a trend was observed to a reduction in staphylococci occurrence toward more advanced stages of the disease. This low prevalence was not related to any variables analyzed. Susceptibility profile to antibiotics demonstrates a raised resistance to penicillin and a low one to methicillin. To erythromycin, tetracycline and clindamycin was observed a significant resistance

Avaliação clínica longitudinal do periodonto de dentes pilares e não pilares de próteses parciais removíveis

The literature has shown a relation between periodontics and the removable partial denture (RPD), with progressive destruction observed in the support structures. The aim of this study was to clinically assess periodontal condition in users of removal partial denture (RPD), and compare right abutments teeth, indirect abutments and controls before installation and after 1 year, in addition to comparing tooth-supported and tooth mucosa-supported abutments. A total of 50 patients, 32 women and 18 men, mean age of 45 years, took part in the study. The patients were examined by a single examiner at prosthesis installation and after 3, 6, 9 and 12 months. The following were verified at each examination: Probe Depth (PD), Plaque Index (PI), Gingival Index (GI), the amount of Keratinized Mucosa (KM), Gingival Recession (GR) and Dental Mobility (DM); in addition patients received oral hygiene orientation, accompanied by prophylaxis, periodontal scaling and root planing (PSRP), when necessary. Analysis of Variance (ANOVA) with Tukey-Kramer post test was used to assess the dependent variables (PD, PI, KM, GR) of the three groups over time while Friedman s test was used for GI. To assess the outcomes of prosthesis type in the right abutment group, a confidence interval-based analysis was performed. The results showed that the control group was the least compromised in all the variables studied. With respect to development of the groups over time, it was verified that the measures for GR, PD, GI and KM increased from initial examination to 1 year of use in all the groups, but only PI showed a significant increase. There was a non-discriminatory low prevalence of dental mobility. The tooth mucosa-supported prosthesis had significantly higher values for GR, GI and PI and significantly lower ones for KM when compared to tooth-supported. Over time, both types of prostheses showed no significant differences from initial to final examination for the variables GR, PD, KM and GI, with PI significant only for tooth-supported. The results showed that the teeth most involved in RPD design had greater potential of periodontal damage, probably because of greater dental biofilm accumulation. Abutments elements adjacent to the free extremities had less favorable periodontal condition than those adjacent to interpolated spaces, but the use of RPD did not worsen the initial condition

Impacto do Programa de Saúde da Família sobre indicadores de saúde bucal na população de Natal -RN

The aim of this study was to assess the impact of the Family Health Program (FHP) on a number of oral health indicators in the population of Natal, Brazil. The study is characterized as a quasi-random community intervention trial. The intervention is represented by the implementation of an Oral Health Team (OHT) in the FHP prior to the study. A total of 15 sectors covered by the FHP with OHT were randomly drawn and paired with another 15 sectors, based on socioeconomic criteria, not covered by the teams. A few sectors were lost over the course of the study, resulting in a final number of 22 sectors, 11 covered and 11 not covered. We divided the non-covered areas into two conditions, one in which we considered areas that had some type of assistance program such as the Community Agents Program (CAP), FHP without OHT, BHU (Basic Health Unit) or no assistance, and the other, in which we considered areas that had only BHU or no assistance. Community Health Agents (CHAs) and Dental Office Assistants (DOAs) applied a questionnaire-interview to the most qualified individual of the household and the data obtained per household were transformed into the individual data of 7186 persons. The results show no statistical difference between the oral health outcomes analyzed in the areas covered by OHT in the FHP and in non-covered areas that have some type of assistance program, with a number of indicators showing better conditions in the non-covered areas. When we considered the association between covered and non-covered areas under the second condition, we found a statistical difference in the coverage indicators. Better conditions were found in covered areas for indicators such as I have not been to the dentist in the last year with p < 0.001 and OR of 1.64 and I had no access to dental care with p < 0.001 and OR of 2.22. However, the results show no impact of FHP with OHT on preventive action indicators under both non-covered conditions. This can be clearly seen when we analyze the toothache variable, which showed no significant difference between covered and non-covered areas. This variable is one of the most sensitive when assessing oral health programs, with p of 0.430 under condition 1 and p of 0.038 under condition 2, with CI = 0.70-0.90. In the analysis of health indicators in children where the proportion of deaths in children under age 1, the rate of hospitalization for ARI (Acute Respiratory Infections) in those under age 5 and the proportion of individuals born underweight were considered, a better condition was found in all the outcomes for areas with FHP. Therefore, we can conclude that oral health in the FHP has little effect on oral health indicators, even though the strategy improves the general health conditions of the population, as, for example child health

Avaliação dos níveis de proteína C-reativa ultra-sensível em pacientes com periodontite crônica severa generalizada e sem periodontite

INTRODUCTION: The high sensitivity C-reactive protein (hsCRP) constitutes an inflammatory mediator used as predictor of cardiovascular risk that comes being researched as indicative relation factor between cardiovascular and periodontal diseases. PROPOSITION: To compare serumals levels of C-reactive protein between patients with and without generalized severe chronic periodontitis. METHODOLOGY: A seccional study was realized using a sample with 62 patients, being 31 participants carriers of periodontal diseases (Group I) and 31 without periodontal diseases (Group II), grouped to the pairs by age and sex. As inclusion criterio were selected patients with diagnosis of generalized severe chronic periodontitis, being preculeds, individuals which presented systemic disease, recent infection history, historical of CVA or stroke, smokers, pregnants and lactants. The research consisted of two stages, a clinc and other biochemist. The clinical stage is constituted of periodontal examination and the biochemist stage, of the peripheral blood collection for determination hsCRP levels and a hemogram to inquire any panel which could suggest infectious and/or inflammatory process. RESULTS: Periodontal disease group presented a average of 0,36mg/dL, while the group without disease presented 0,17 mg/dL, do not existing significant difference statistically between the averages (p = 0,061). The cardiovascular risk for the group I was classified high for 27,6% of participants and low for 72,4% of them. In the group II, 6,45% presented high risk e 93,5% low risk, being this significant relation statistically gotten for Fisher s Test (p = 0,042) presenting OR = 5,33; IC = 95% (1,02 27,4). The independets variables reseacred do not presented significant association statistically with the levels of hsCRP. CONCLUSION: The study indicated that despite of carriers patients of periodontal diseases do not present differents serumals levels of hsCRP from the other group, the periodontal disease was considered as risk factor for hsCRP plasmatic levels elevation

Conhecimento sobre ergonomia no âmbito acadêmico: um estudo com alunos e professores de odontologia

OBJETIVO: As doenças osteomusculares são as afecções ocupacionais mais prevalentes em cirurgiões-dentistas. Nosso propósito: 1) investigar os conhecimentos, aplicabilidades clínicas dos princípios ergonômicos em discentes e docentes em atividades clínicas de uma universidade pública 2) pesquisar a incidência de sintomatologias dolorosas no pescoço, ombros, parte superior e inferior das costas, cotovelos, quadris, coxas, joelhos, tornozelos e pés no universo de alunos em estágios clínicos. 3) incitar discussões de normas e diretrizes ergonômicas na universidade. MÉTODOS: Esse estudo investigou o universo de alunos matriculados em disciplinas clínicas (148) e respectivos professores (30) do curso de odontologia da Universidade Federal do Rio Grande do Norte, Natal-RN a respeito dos princípios ergonômicos utilizados na rotina clínica. Paralelamente foi pesquisada a incidência de sintomatologia dolorosa nos alunos por intermédio do questionário nórdico e a partir dos resultados foi mensurado o índice de severidade dos sintomas em alunos. The Nordic Musculoskeletal Questionnaire (NMQ) é um instrumento de diagnóstico, proposto para padronizar a mensuração de relatos de sintomas osteomusculares. A análise dos dados foi através do programa SPSS-Statistical Package for the Social Sciences, versão 17.0 realizada analítica e descritivamente, com determinação das médias (x), desvio-padrão para variáveis quantitativas, freqüências simples e relativas para as variáveis categóricas, além da estatística de associação entre grupos (teste t) e a análise de associação do quiquadrado com nível de significância 5% entre as variáveis (Person). As respostas das questões abertas foram codificadas e transformadas em freqüências, descritas posteriormente. RESULTADOS: A aplicabilidade de medidas ergonômicas nas clínicas universitárias não foi evidenciada pelo universo de discentes e docentes. Quanto ao relato de sintomas osteomusculares o sexo feminino foi o mais acometido qualquer que seja o nível acadêmico cursado. As regiões anatômicas de maior grau de severidade de relatos dos sintomas foram: pescoço, parte inferior das costas, punhos, mãos e ombros, com significância etatística p<0,001. CONCLUSÃO: Em função dos achados os autores apresentam um protocolo de intervenção clínica baseado nos determinantes ergonômicos da Associação internacional de ergonomia (EAI) como medida de prevenção da saúde ocupacional dos futuros cirurgiões-dentistas ainda em processo de formação nas clínicas odontológicas das universidades.
