Objective: To prospectively evaluate the incidence of peri‐implant diseases and the associated risk factors during 11 years of peri‐implant maintenance therapy (PIMT). Material and Methods: A sample of 80 partially edentulous individuals rehabilitated with dental implants was invited to participate in a PIMT program (T1—prior to entering the PIMT program). After 11 years, 51 individuals remained regularly or irregularly adherent to PIMT (T2—last recall after 11 years) and were classified as regular (RC; n = 27) or irregular (IC; n = 24) compliers. Data of interest were analyzed using univariate and multivariate logistic regression analyses. Results: The incidence of peri‐implant mucositis and peri‐implantitis observed at T2 in the IC group (70.8% and 37.5%, respectively) were significantly higher than those observed in the RC group (37.0% and 11.1%, respectively). The incidence of peri‐implant diseases was mostly attributable to potentially modifiable risk factors, as such: RC group—PM (p = 0.013); IC group—high plaque index (p < 0.001), irregular compliance (p < 0.001), the presence of PM (p = 0.015) and periodontitis (p < 0.039). Conclusion: Regular compliance during PIMT had a strong effect in minimizing the incidence of peri‐implant diseases. Increasing regular dental visits and improving oral hygiene would provide benefits for preventing peri‐implant diseases. [ABSTRACT FROM AUTHOR]

Background: The aim of this study was to evaluate the effect of supragingival plaque control on the recurrence of periodontitis (RP) and the achievement of a stable periodontal clinical endpoint after 10 years of periodontal maintenance therapy (PMT).Methods: The present retrospective cohort study included 225 individuals in continuous PMT. The plaque index (PI) determining the oral hygiene (OH) status, periodontal clinical parameters, and other variables of interest were collected at three time points: T1 (prior to active periodontal therapy [APT]), T2 (after APT), and T3 (10 years after T2). According to PI records at T3, participants were categorized into: (1) good OH (GOH; PI ≤ 30%, n = 63); (2) fair OH (FOH; PI > 30% and ≤40%, n = 73); and (3) poor OH (POH; PI > 40%, n = 88). Data were analyzed using the chi-square and Student t tests, analysis of variance (ANOVA), and mediation and regression analyses.Results: Significant differences in all periodontal clinical parameters between the GOH, FOH, and POH groups were observed at T3. The POH group exhibited higher mean bleeding on probing (BOP), periodontal probing depth (PD), and clinical attachment level (CAL), as well as higher tooth loss (POH > FOH > GOH; P < .001). There was an increased risk for RP in the FOH (odds ratio [OR] 2.02; CI, 1.10-4.38) and POH (OR 4.33; CI, 2.17-8.65) groups. Moreover, the FOH and POH groups had an approximately 2.5 and 6.0 times greater chance of not achieving a stable periodontal clinical endpoint, respectively.Conclusions: After 10 years of monitoring in PMT, individuals with higher PI scores (>30%) presented an unhealthier periodontal status, a higher risk for RP, and a lower chance of achieving ≤4 sites with PD ≥ 5 mm.

Aim: To determine the impact of the degree of furcation involvement (FI) on the longevity of molar teeth and assess the risk variables (tooth‐ and patient‐related factors) associated with the loss of molars (LM) in individuals treated for periodontitis and monitored in a private programme of supportive periodontal care (SPC). Materials and Methods: The present retrospective cohort study included 222 individuals with 1329 molars under a 10‐year monitoring period in SPC. Periodontal clinical parameters, FI, the type of molar, pulp vitality, and other variables of interest were collected at approximately 50 days after active periodontal therapy and after 10 years. The association of tooth‐ and patient‐related factors with LM was assessed using a multilevel Cox regression analysis. Results: Two‐hundred and thirty‐five molars were extracted during the SPC period of 12.4 ± 1.9 years. Age >50 years, male gender, diabetes, smoking, and non‐compliance were identified as relevant patient‐related factors for LM during SPC (p <.05). Significant tooth‐related factors for LM were bleeding on probing (BoP) and probing depth (PD) ≥5 mm, tooth non‐vitality, and class II and III FI (p <.05). Conclusions: Class III FI, tooth non‐vitality, higher mean PD and BoP, age, male gender, diabetes, and smoking all strongly influenced the prognosis of molars during SPC. [ABSTRACT FROM AUTHOR]
