Objective This current study is aimed to analyze the prognostic factors affecting the short-term efficacy of non-surgical treatment of patients in periodontitis from stage II to stage IV by the multilevel modelling analysis.
Materials and Methods A total of 58 patients of chronic periodontitis were included in this study. Patients were clinically explored before and 3 months after the treatment, with the data of Δ probing depth (PD) [Δ PD = baseline PD – finial probing depth (FPD)] as the outcome variables. All the data were divided into site level, tooth level and patient level to construct a multi-layer linear model.
Results Compared with the mesial sites and distal sites of the multi-rooted teeth, the number of PD ≥ 5mm or PD < 5mm after the treatment was significantly different ( P < 0.05), and the proportion of PD < 5mm was higher in mesial sites. The null model showed that Δ PD varied greatly between groups at various levels ( P <0.001), with prediction variable of site level, tooth level, and patient level accounted for 66%, 18%, and 16% of the overall difference, respectively. The complete model showed that the Δ PD of smokers was significantly lower than that of non-smokers ( P < 0.001). The Δ PD of the mesial and distal sites was larger than that of the buccolingual central site ( P < 0.001). The Δ PD of single-rooted teeth was larger than that of multi-rooted teeth ( P < 0.001). The baseline PD, tooth mobility (TM), bleeding index (BI), clinical attachment loss (CAL) were significantly negatively correlated with Δ PD ( P < 0.001).
Conclusions Patients with periodontitis from stage II to stage IV, who are non-smoking, have good compliance, good awareness of oral health, and low percentage sites with PD ≥ 5mm at baseline, single rooted teeth with hypomobility, less CAL and lower BI and sites of mesial or distal can obtain an ideal short-term efficacy of non-surgical treatment.
