- Predictors of tooth loss during long-term periodontal maintenance : an updated systematic reviewPublication . Carvalho, Rui Pedro Matos de; Mendes, José João; Chambrone, Leandro; Botelho, JoãoAim: To evaluate the risk factors / predictors of tooth loss in patients with periodontitis who underwent periodontal therapy and long-term periodontal maintenance (PM). Material & Methods: PUBMED, CENTRAL, EMBASE, Web of Science, LILACS and Google Scholar databases were searched until September 2020. Studies limited to periodontitis patients who underwent active periodontal therapy and followed a regular PM program with at least 5 years of follow-up were considered for inclusion. Studies were included if data on tooth loss during PM were reported. Random effects meta-analyses of number of tooth loss per patient per year were conducted. Results: Thirty-six papers regarding thirty-three studies were included, with three prospective and 30 retrospective trials. Subgroup meta-analysis showed no difference between prospective and retrospective studies, with an average of 0.1 tooth loss per year per patient (p<0.001). Maxillary and molar teeth were more susceptible to be extracted during long-term PM. Baseline characteristics (smoking, diabetes mellitus, cardiovascular disease, being male, and teeth with furcation lesions) showed no significance as predictor of tooth loss through meta-regression. The percentage of tooth loss due to periodontal reasons ranged from 0.45% to 14.4%. Individual outcomes in each study evidenced different patient-related factors (age and smoking) and tooth-related factors (i.e., tooth type and location) were associated with tooth loss during PM. All analyses showed complete homogeneity (I2=0%). Conclusion: Most patients undergoing long-term PM have not lost teeth. Long-term PM causes the loss of 1 tooth per patient every 10 years. Additional prospective trials may confirm these results.
