Abstract

Objectives

The identification of predictors of supragingival biofilm accumulation may improve the results of therapeutic strategies for dental caries and periodontal diseases in general clinical practice. This study aimed to determine predictors of changes in visible plaque (VP) and gingival bleeding (GB) during integrated dental care.

Materials and methods

A retrospective longitudinal study was conducted by a census of patients receiving integrated dental care in a general clinical practice ambulatory at the Federal University of Rio Grande do Sul (Brazil). The sample comprised 91 charts of patients attended over a 6-months period. Gender, age, patient’s main complaint, oral hygiene pattern, and clinical data were recorded from charts for the last two dental visits in the ambulatory. Changes in VP and GB were modeled by multiple linear regression and beta coefficients (b) were reported.

Results

The mean follow-up time was 13 months. Significant reductions in VP (32.8 ± 27.9 to 17.4 ± 19.4%; p < 0.001) and GB (27.1 ± 23.8 to 18.5 ± 17.3%; p < 0.001) were observed. Higher plaque reductions were predicted by higher baseline VP levels (p = 0.02), shorter time (< 12 months) elapsed between VP recordings (b = 14.1%, p = 0.02), interproximal cleansing (b = 11.9%, p = 0.03), lower number of sessions for oral hygiene instruction (b = 13.7%, p = 0.02), and presence of pockets ≥ 6 mm (b = − 12.4%, p = 0.02). GB was predicted by time of follow-up > 12 months and baseline VP.

Conclusions

Plaque and gingivitis improved in patients under integrated dental care. Factors related to motivation, oral hygiene practices, and baseline periodontal status might be used as predictors of VP and GB changes.

Clinical relevance

Visible plaque and gingivitis reduced in a sample of patients treated under integrated dental care. Some predictors may determine for which patients the treatment may be maximize and those who will need greater efforts to achieve the therapeutic goal for oral hygiene.
