Parâmetros clínicos periodontais e variáveis preditoras de risco para perda dental, progressão e recorrência de periodontite: um estudo follow-up de 78 meses em terapia periodontal de suporte em instituição pública

Abstract

This prospective study "follow-up" aims to evaluate the recurrence, periodontitis progression and tooth loss associated with predictable risk variables in individuals within a program of supportive periodontal therapy (SPT) in public/academic environment. During 78 months of SPT, 39 individuals considered regular compliers (RC) and 52 irregular compliers (IC) were monitored with mean interval between visits of 6 and 13 months, respectively. Complete periodontal examination was conducted for evaluating probing depth (PD), clinical attachment level (CAL) and presence of bleeding on probing (BOP) in two exams, SPT baseline and final. Futhermore, collection was performed predictors of risk social, demographic and behavioral factors. Univariate and multivariate logistic regression were performed if appropriate. Progression, recurrence and tooth loss were significantly higher in IC than RC. Higher severity parameter PD (sites with PD > 7 mm) were reported in IC (IC> RC). An annual rate of tooth loss of 0.18 was reported for RC and 0.30 for IC (p = 0.031). Age and > 30% sites with CAL 4 mm were associated with progression of periodontitis. Smoking status, co-habitation, family income and > 30% sites with BOP were associated with recurrence. In addition, age, family income, low frequency of toothbrushing and diabetes were associated with tooth loss. Conclusions: RC showed less progression, recurrence and tooth loss when compared to IC. These results corroborate the influence of the pattern of cooperation in SPT on periodontal health maintenance.
