Evaluation of partially dentate patients' knowledge about caries and periodontal disease

Objective: This investigation evaluated the knowledge of dental caries and periodontal disease among removable partial denture (RPD) wearers.Method: A total of 127 partially dentate patients participated in this observational study. A structured questionnaire, which included eight questions referring to knowledge about aetiology and prevention of dental caries and periodontal disease, was developed in the local language (Portuguese) and used to collect the data of all the partial denture wearers. A descriptive analysis of data was performed by means of drafting tables.Results: The results demonstrated that 68.5% of patients interviewed had previously received information about oral health care. With regard to bacterial plaque, it was observed that only 34.6% reported having knowledge of this. Whereas, in relation to caries, 76.4% of the interviewees replied that they knew the meaning of this. Nevertheless, 28.3% referred to caries as a whole in the teeth, 16.5% as bad teeth and 9.4% bacteria/creatures on the teeth. Only 17.3% of the partially edentulous patients evaluated were shown to know what disease of the gingiva was.Conclusion: By means of the methodology applied, it could be concluded that the patients who wore RPDs presented deficient knowledge with regard to the prevention, aetiology and development of dental caries and periodontal disease.

Ansiedade frente ao tratamento odontológico: prevalência e fatores predictores em brasileiros

Diante do impacto negativo que a ansiedade exerce sobre o atendimento odontológico, buscou-se conhecer sua prevalência e seus fatores predictores frente esse tratamento em brasileiros. Foi realizado um estudo de corte transversal, utilizando-se a escala de ansiedade de Corah para avaliar 3000 pacientes. Os resultados demonstram que 2 em cada 8 brasileiros avaliados apresentaram moderada ou severa ansiedade frente ao atendimento odontológico, verificando-se que a probabilidade de um paciente da população da qual a amostra foi extraída apresentar ansiedade é mais elevada se: for mulher (p = 0,007), da faixa etária superior a 20 anos (p = 0,006), se não possuir acesso a internet e/ou jornais (p = 0,016), se tiver baixa frequência de higiene oral (p = 0,001), se a visita dental for motivada por busca de tratamento curativo, por dor ou outro problema, ao invés de um check-up (p = 0,047), e experiência de odontalgia (p<0,001). O medo e a ansiedade a fatores odontológicos existem de fato na população brasileira e as conclusões do estudo sugerem que, além da falta de recursos econômicos, o descaso com a saúde bucal, o gênero e a idade podem aumentar o grau de ansiedade.

FRÊNULO LABIAL SUPERIOR E INFERIOR: ESTUDO CLÍNICO QUANTO A MORFOLOGIA E LOCAL DE INSERÇÃO E SUA INFLUÊNCIA NA HIGIENE BUCAL

Foi realizada uma pesquisa visando a avaliação morfológica e o local de inserção dos frênulos labiais superiores e inferiores. A amostra foi constituída de 100 pacientes em condições sócio-econômicas semelhantes, tendo-se observado que o frênulo labial simples foi o mais prevalente, inserindo o superior na gengiva inserida e o inferior, na mucosa alveolar. A distância média da inserção, em relação à borda gengival livre, foi de 4,4 mm para o superior e de 5,6 mm para o inferior. Foi possível, nessas áreas, manter o controle clínico da placa bacteriana

Avaliação do conhecimento popular e práticas cotidianas em saúde bucal

OBJETIVO: Avaliar o conhecimento popular e as práticas cotidianas em saúde bucal de usuários de serviços públicos de saúde. MÉTODOS: A população estudada foi selecionada a partir de uma amostra estratificada de usuários que procuraram atendimento nas unidades sanitárias da zona urbana de Santa Maria, RS. Os dados foram coletados por meio de entrevista semi-estruturada e organizados em conjuntos de categorias descritivas, permitindo sua distribuição em tabela de freqüência. RESULTADOS: Verificou-se que predominam usuários entre 21 e 40 anos de idade, do sexo feminino e com padrão socioeconômico baixo. A busca pela saúde e o controle das doenças bucais são atribuídos à responsabilidade individual de realizar a higiene bucal e procurar tratamento dentário. A presença e os benefícios do flúor no creme dental e na água de beber não foram reconhecidos pela população estudada. CONCLUSÕES: Os programas de saúde devem considerar os aspectos relativos ao conhecimento e as práticas em saúde bucal, para viabilizar o processo de capacitação da população e promover a responsabilização coletiva da promoção da saúde em todos os níveis da sociedade.

Clinical evaluation of abutment teeth of removable partial denture by means of the Periotest method

Prosthodontics should be one of the means of establishing conditions for the maintenance of periodontal health. The forces applied to the abutment teeth and their effects are very important considerations in the design and construction of the removable partial dentures. This 6-month follow-up clinical study evaluated the degree of mobility of abutment teeth of distal extension and tooth supported removable partial dentures by using Periotest. Two types of clasp design were selected for evaluation. In cases with unilateral and bilateral distal-extension, a clasp design including a T clasp of Roach retentive arm, a rigid reciprocal arm and a mesial rest were used. For the abutments of tooth-supported removable partial dentures, a second clasp design with a cast circumferential buccal retentive arm, a rigid reciprocal clasp arm and a rest adjacent to the edentulous ridges was selected. A total of 68 abutment teeth was analysed. Periotest values were made at the time of denture placement (control) and at 1, 3 and 6 months after the denture placement. The statistical analysis was performed using Friedman test. All analysis was performed at a 0.05 level of significance. The results revelled that no significant changes in tooth mobility were observed during the 6-months follow-up (P > 0.05). In conclusion, our findings suggest that adequate oral hygiene instructions, careful prosthetic treatment planning and regular recall appointments play an important role in preventing changes in abutment tooth mobility caused by removable partial denture placement.

Effect of Supragingival plaque control in smokers and never-smokers: 6-month evaluation of patients with periodontitis

Background: the effect of supragingival plaque control on clinical signs of periodontitis is controversial, particularly when smoking habits are considered. This study evaluated the clinical effects of supragingival plaque control on clinical signs of periodontitis in smokers and never-smokers.Methods: the following data were collected for 25 never-smokers and 25 smokers at baseline and 30, 90, and 180 days: visible plaque index (VPI), gingival bleeding index (GBI), bleeding on probing (BOP), periodontal probing depth (PD), and clinical attachment loss (CAL). After baseline examinations, supragingival scaling was performed. Oral hygiene practices were reinforced and reevaluated weekly during the experimental period. Linear models adjusted for clustering of observations within individuals were used for statistical analysis.Results: Reductions in VPI were significant for both groups, with no intergroup differences. GBI at baseline was similar between groups, and at 30, 90, and 180 days, smokers had a lower GBI than never-smokers. Significant reductions were observed in PD for shallow (1 to 3 mm), moderate (4 to 5 mm), and deep sites (>= 6 mm) in both groups. CAL was significantly greater in smokers throughout the study, but gains in attachment were similar for both groups (0.71 to 1.00 mm). BOP reductions were similar in both groups.Conclusions: Supragingival plaque control resulted in significant changes in clinical parameters associated with gingivitis and periodontitis. Smoking did not affect results, regardless of initial PD.

A clinical follow-up study of the periodontal conditions of RPD abutment and non-abutment teeth

The purpose of this study was to evaluate the periodontal conditions of removable partial denture (RPD) wearers, comparing direct and indirect abutment teeth, and the teeth not involved in the denture design before denture placement and 1 year later. Fifty patients (32 women and 18 men), average age 45, were assessed by the same examiner at the moment of denture insertion and 3, 6, 9 and 12 months later. The following items were verified in each assessment: probing depth (PD), plaque index (PI) and gingival index (GI). PD and PI data were evaluated by ANOVA test for linear trend followed by Tukey-Kramer post-test, while GI data were analysed by Friedman's test. Results showed that the teeth not involved in the denture design were the least affected for all variables studied. It was also verified that PD and GI mean values increased from the initial assessment to 1 year of RPD wearing in every group, but that only PI showed a significant increase. This study indicated that direct and indirect retainer elements tend to undergo more damaging periodontal effects associated with RPD wearing when compared with non-abutment elements. Plaque index values were significantly higher after 1 year of denture use.

CPITN: time and cost estimates for periodontal prevention and treatment procedures.

The aim of this study was to estimate the necessary time and cost for periodontal prevention and treatment in a working population from sugar and alcohol refineries in Araraquara, SP, Brazil. A stratified sample of 528 employees aged 18-64 from administrative, industrial and agricultural staffs was examined by one examiner, previously trained, according to the community periodontal index of treatment needs (CPITN). The time required for procedures and the cost was extrapolated to the total worker population. The results showed that the estimated time required for periodontal prevention/treatment was 4527 hours. Of this time, 1783 hours were required for oral hygiene instruction, 2531 for scaling, 151 for surgery and 62 for maintenance. The cost would be US $17,655 for hiring a dentist for 8 hours/day to provide oral hygiene instruction, scaling, surgery and maintenance. However, the cost would be US $9,028 for hiring a dentist for 4 hours/day to provide surgery and maintenance and a dental hygienist for 8 hours/day to provide scaling and oral hygiene instruction. Taking into account epidemiologic, technical and economic aspects, the decision relating to manpower should be this second option.
