Dental caries and related factors in Brazilian children from fluoridated and non-fluoridated areas

PURPOSE: To compare the caries prevalence, saliva buffering capacity (SBC), oral hygiene (OH), dietary habits, family income (FI) and frequency of visits to a dental office (Do) between Brazilian children living in areas with and without fluoridated public water supply. METHODS: Forty-six 5-7-year-old preschoolers were selected in Itatiba, SP, Brazil; 19 were from a fluoridated area, and 27 were from a non-fluoridated area. The caries index was determined according to the World Health Organization criteria, and the SBC was assessed by titration with hydrochloric acid. The FI, frequency of OH and visits to Do were estimated by questionnaire. The dietary habits were assessed with a diet chart. The differences between the groups were analyzed with Mann-Whitney-U tests (α=0.05). RESULTS: Children from the non-fluoridated area showed significantly higher dmft/DMFT than those from the fluoridated area, but they showed significantly lower SBC, OH frequency and FI. No significant differences were observed between the areas for dietary habits and visits to Do. CONCLUSION: Children from fluoridated areas showed higher salivary buffering capacity, family income and oral hygiene frequency as well as lower caries prevalence, supporting the beneficial effect of fluoride in the tap water for caries prevention.

Importância da abordagem precoce no tratamento odontológico de pacientes portadores de necessidades especiais.

Introduction: the patients with specials necessities ne ed a singular dentistry treatment because they have limitations due to theirs deficiency. The quality of oral health is related to the clinical situation of patient. The individuals with motor and understanding problems have poor oral health. Aim: this st udy aimed to review the literature about the importance of the early dentistry treatment of pacients with specials necessities. Methodology: the review of literature was made through t he Pubmed and Bireme. Studies about dental caries and periodontal dise a se of patient s with specials necessities had shown high index of caries and periodontal disease. Therefore it is important that there are capacity p rofessionals and multidisciplinary treatment. It is necessary to supply the dificulties of treatment like an xiety of parents, systemic problems and discrimination. Conclusion: the early treatment results in good coperation during the treatment, and the aquisition of cares for all life. The best way is a program of oral health with instructions about diet, oral hygiene, control of bacterials, motivation and interaction between patients and professionals.

Cariogenicidade do leite materno: mito ou evidência científica

Introduction: Breast-feeding has stood out as health care measure and is part of the Government’s National Health Policy, involving dental professionals. However, it has been suggested that breast milk could be a risk factor for the development of early childhood caries. Objective: The purpose of this report was to search for scientific evidence that would support or refute the statement that breastfeeding is associated with the development of early childhood caries. Method: Medline and SciELO databases were consulted to retrieve studies, ranging from laboratory investigations to epidemiological surveys, which relate breastfeeding to dental caries. The key words ‘breast-feeding’ and ‘dental caries’ were used on the reference search. There was no scientific evidence that could demonstrate a clear relationship between breast milk and cariogenicity. This is attributed to fact that dental caries is a multifactorial disease that is susceptible to multiple confusing factors, among which the early introduction of sucrose to the infant’s diet and late introduction of oral hygiene habits. The dentist should encourage exclusive breast-feeding because, in addition to the undeniable benefits to the child’s physical and psychological health, it contributes to a harmonic facial growth and prevents the development of atypical deglutition and malocclusions, in combination with early introduction of oral hygiene habits and noncariogenic diet. Conclusion: There is no scientific evidence to demonstrate an association between breast-feeding and early childhood caries.

Higienização em prótese sobre implante

With the advances of osseointegration principles, the use of implant-supported prosthesis has become a routine treatment option. The success of an implant is initially associated to the surgical technique, primary stability and absence of bacterial contamination on the implant site. Subsequently, the absence of mechanical trauma (overload) and peri-implantitis are sine qua non conditions to the longitudinal success of implant treatment. Therefore, the strict maintenance of oral hygiene is highly important to avoid biofilm accumulation around the implant and consequently to provide last-long implant-supported dentures. The clinician has the responsibility to supply a favorable prognosis to the patient so that the rehabilitation succeed. For this reason, during prosthesis fabrication the clinician should observe the design and emergency profile of the prosthesis, the peri-implant sulcus depth as well as the presence of motor or psychological impairment by the patient. Subjects with missing teeth and that will be submitted to the implant treatment should be motivated and adequate instructed regarding oral hygiene and its importance since the best option to obtain treatment longevity and consequently patient’s satisfaction is the prevention. Therefore, this study aimed to perform a literature review about the hygiene of implant-supported prosthesis.

Impacto do controle glicêmico sobre as complicações associadas ao diabetes mellitus na osseointegração

The increased prevalence of diabetic individuals has become a public health problem. Diabetes Mellitus is a metabolic disorder characterized by an increase in plasma glucose levels. It impairs the physiological equilibrium in utilization of carbohydrate by tissues. The persistent hyperglycemia can produce deleterious effects on bone formation due the microvascular complication. The present paper reviews the bibliography linking the impact of glycemic control at complications associated at diabetes mellitus on osseointegration. In experimental models of diabetes it was observed a reduced level of bone-implant contact. This failure can be reduced by means of hyperglycemia control. Also, several studies point the beneficial effect of coated implant on osseointegration process. It is necessary to take special care into account for the placement of implants in diabetic patient and improve the percentages of implant survival. A rigorous control of plasma glycaemia, together with other measures, like as absence of chronic complications, good oral hygiene and regular medical follow-up has been related to rising the percentages of successful in diabetic patients.

Halitose na geriatria: diagnóstico, causas e prevalência

Halitosis is the unpleasant odor of exhaust air through the mouth and lungs. There are over 50 causes, and approximately 90% of cases, is of oral origin. May have physiological origin (stress, breath of morning, fasting, and inappropriate diets), local reasons (bad oral hygiene, bacterial plaque retained on the tongue and/or tonsils, lower production of saliva, gum disease) or systemic reasons (diabetes, kidney or liver problems, constipation, etc.). In the Third Age, this problem tends to increase significantly. Thus, the aim of this study was to detect the presence of halitosis in the geriatric group attended in the dental clinic of UNIRP, identifying their incidence and principal causes. The sample consisted of 48 volunteer patients aged 60 years or older and included more than 90% of patients treated in this age group. It was performed a anamnesis and physical examination. The intra-oral halitosis was detected using a breath meter (halimeter). In the group studied, approximately 54.16% had halitosis, 84.61% of these were users of the prosthesis. The tongue coating was present in 80.76% of individuals with halitosis. After brushing the tongue, 88.46% of patients with halitosis have had the initial index oral malodor decreased. Based on the results of this study it was concluded that factors as dental prostheses and tongue coating are critical factors in causing halitosis.

Efeitos da radioterapia sobre as condições bucais de pacientes oncológicos

This study evaluated the oral conditions of 50 cancer patients undergoing head and neck radiotherapy (RT). Clinical examinations were performed before treatment, immediately after 30 days after RT and 6 months after conclusion of RT. Periodontal conditions were evaluated using the criteria of the Periodontal Screening and Recording (SRP) and the need for dental treatment were determined. The presence of xerostomia, mucositis and other side effects of RT were also evaluated. Soon after the beginning of RT, the irradiated patients of radiotherapy developed severe mucositis, dermatitis, dysgeusia, xerostomia and, to a lesser extent, candidosis. After completion of radiotherapy, 68% of patients had level III or IV mucositis. It was found that the development of mucositis hinders oral hygiene and these factors contribute to exacerbate inflammation of periodontal tissues. The data from this study evidenced that the main cause of desertion of RT and of severity of sequelae of RT depends on the oral conditions of patients before starting treatment and the absence of previous dental treatment prior RT.

Helicobacter pylori em boca: epidemiologia e associação com doenças bucais

The association of Helicobacter pylori with different gastric diseases has been continuously discussed in the literature, whereas the last 20 years a large body of publications was intended to characterize the ecological niches and habitats of this pathogen being the mouth a possible habitat for that rod. The present study aimed to discuss the occurrence of this organism as part of the supplemental or transient microbiota of the mouth. Thus, an extensive review of literature covering the period 1990-2014 was carried out with different databases, yielding 5024 articles discussing transmission and occurrence of H. pylori, in English or Portuguese. Articles were selected according to the inclusion and exclusion criteria and data were tabulated and analyzed. Despite the significant heterogeneity of the literature, it was found this microaerophilic has a worldwide distribution, even in the mouth, which behaves as a reservoir for gastric reinfection. The role of oral hygiene and periodontal disease in the distribution of this microorganism remains unclear, but most studies support the hypothesis that oral biofilms and inflammation of periodontium may facilitate the installation of this pathogen in the mouth. Studies suggest that this microorganism could collaborate as a predisposing factor for oral cancer.

Relação entre a composição de condicionadores capilares e a formação de cristais líquidos

O Brasil é o terceiro maior consumidor de cosméticos no mundo, representando a segunda colocação em produtos de higiene capilar. Tal colocação está relacionada aos nossos padrões de cuidados estéticos capilares, que muitas vezes, provocam agressões físicas e químicas, deixando os cabelos danificados e quebradiços. Os condicionadores capilares tornam-se uma ferramenta interessante, devido aos inúmeros benefícios protetores oferecidos às superfícies dos fios. A presença de tensoativos catiônicos e álcoois graxos de cadeia longa, unidos à temperatura de fusão dos materiais, velocidade de agitação imposta e resfriamento adequado do produto, podem ser os responsáveis pela formação de cristais líquidos. Tais estruturas conferem estabilidade, viscosidade, melhorias na aparência estética e sensorial do produto e, devido a estas qualidades estão ganhando espaço no mercado cosmético. Assim, o objetivo do trabalho foi desenvolver e formular condicionadores capilares variando-se as concentrações e/ou os tensoativos catiônicos e álcoois graxos, visando obter estruturas líquido-cristalinas associadas aos condicionadores, através da técnica de microscopia de luz polarizada (MLP), caracterização das estruturas pela técnica de espalhamento de raios-X a baixo ângulo (SAXS) e analise do perfil de textura (TPA) das formulações. Foram manipuladas 14 emulsões O/A, variando-se os álcoois graxos de cadeia longa (16 a 18C) e ceras auto emulsionantes catiônicas. Os resultados da MLP foram, em sua maioria, positivos para a presença de estruturas na forma de cruz de malta. A técnica de SAXS confirmou os sistemas sugeridos pela MLP caracterizando a estrutura líquida cristalina do tipo lamelar. A TPA inferiu que a alta estabilidade física apresentada por estas emulsões, e seu particular desempenho no deslizamento dos cabelos, pode estar relacionada à presença de tal organização estrutural nas formulações...

Oral manifestations in HIV+ children in Mozambique

O objetivo deste estudo foi identificar a prevalência das manifestações bucais em pacientes HIV+/SIDA do Hospital Pediátrico DIA de Maputo. Foram incluídos 90 pacientes na pesquisa. Cárie dentária (índice ceod/CPOD), mucosa e fluxo salivar foram avaliados. Informações sobre alimentação e hábitos de higiene bucal foram obtidas por meio de um questionário. Para a análise estatística foram utilizados os testes t-student e qui-quadrado. A lesão oral mais frequente foi a candidíase (5,5%) e no exame extra-oral foi observada uma prevalência de alargamento da parótida de 23%. A média do ceod foi 2,6 (± 3,6) dentes, consideravelmente alta em relação ao CPOD que foi de 0,6 (±1,6) dentes, sendo esta diferença estatisticamente significante (p<0,05). A ocorrência de lesões na mucosa bucal foi maior em crianças que não faziam uso da terapia antiretroviral (TRA). O uso da TRA esteve associado com a redução da prevalência de lesões bucais em pacientes HIV+, contudo cáries rampantes foram maiores neste grupo. Pacientes HIV+ mostraram maior risco de cáries na dentadura decídua.
