Oral health conditions and self-perception among edentulous individuals with different prosthetic status

Aim: To evaluate the objective oral health conditions and self-perception of edentulous individuals wearing functional complete dentures (FCD) and non-functional complete dentures (NFCD) and completely edentulous non-denture wearers, and identify the factors that influence self-evaluation and the impact on quality of life. Methods: The convenience sample was selected at the integrated clinic of a Dentistry Course (n=193) and was divided into 3 groups: FCD wearers (n= 54); NFCD wearers (n= 65); 3- edentulous non-denture wearers (n= 74). Data collection was performed by means of interviews, application of the Geriatric Oral Health Assessment Index (GOHAI) andclinical exams. Data were submitted to univariate analysis and logistic regression, considering dichotomization of the sample by the median value of GOHAI (=30). Results: Individuals with NFCD are 4.5 times more likely to show a low GOHAI score than individuals with FCD; edentulous individuals are 7.5 times more likely to show a low GOHAI score than individuals with FCD; individuals that consider their oral health as regular, poor or bad are 3.1 times more likely to show a low GOHAI score than individuals who consider their oral health as good or excellent. Conclusions: Being completely edentulous or wearing NFCD, and having oral health classifiedas regular, poor or extremely bad were important features for a negative self-perception of oral health, with impact on quality of life.

Estudo clínico, microbiológico e histopatológico da estomatite por dentadura / Clinic, microbiologic and histophatologic study of the denture stomatitis

Estomatite por dentadura é a alteração que acomete a mucosa de suporte das próteses totais e que se caracteriza por hiperemia e edema, podendo a inflamação ser moderada ou intensa. A etiologia mostra-se extremamente variável, sendo considerada de causa multifatorial. Com o objetivo de estabelecer a prevalência de espécies de Candida no processo de estomatite por dentadura, examinou-se a superfície interna de próteses totais superiores e a mucosa do palato de 36 pacientes que apresentavam estomatite por dentadura. Para este estudo foram realizados os exames clínico, citológico e histológico, com o auxílio de microscopia de luz. A citologia esfoliativa evidenciou 19 por cento de positividade para Candida, e de 100 por cento para bactérias, enquanto que o esfregaço das próteses totais permitiu verificar a presença de Candida em 80 por cento, e de bactérias em 100 por cento dos casos avaliados. O exame histopatológico demonstrou basicamente, um quadro inflamatório e perda de integridade do epitélio, não sendo evidenciadas espécies de Candida nos tecidos
