Prevalence and risk indicators of buccal gingival recessions in a Moroccan periodontitis patients: A retrospective study.

Background: This study investigates the prevalence, distribution and risk indicators of buccal gingival recessions (GRs) in periodontitis patients. Methods: A retrospective examination of 400 periodontitis patients files was performed using an operating sheet. Univariate logistic regression analysis was performed to identify risk indicators of GRs. Multivariate regression analysis was conducted for selected variables with p < 0.05. Results: 354/400 (88.5 %) patients have at least one GR ≥ 1 mm. The prevalence of recession type (RT) at the patient level was 0.5 %, 2.25 % and 85.75 % for RT1, RT2 and RT3 respectively. Lower incisors are the most affected teeth (79.8 %). Upper canines present the lowest frequency (41.8 %). The univariate logistic regression showed that age (SE = 0.021; 95 % CI 1.01-1.10; p = 0.006), plaque index (SE = 0.50; 95 % CI 1.49-10.50; p = 0.006), level of plaque control (SE = 0.529; 95 % CI 0.90-0.72; p = 0.010) and periodontitis stage (SE = 0.41; 95 % CI 1.41-7.07; p = 0.005) were significantly associated with the presence of GR. In the multivariate regression model, significant results were confirmed only for age (SE = 0.021; 95 % CI 1.02-1.17; p = 0.006) and periodontitis stage (SE = 0.41; 95 % CI 1.35-6.75; p = 0.007). Conclusion: The cross-sectional study showed a high prevalence of GRs. Lower incisors were the most affected teeth. Most patients have GRs with advanced interproximal attachment loss (RT3 GRs). Age, plaque index, level of plaque control and periodontitis stage resulted as risk indicators of GRs.

Prevalence and risk indicators of peri-implant diseases in a group of Moroccan patients.

BACKGROUND: To report the prevalence of peri-implant diseases in a North African patient population, and to assess the concurrent associations of patient- and implant-level characteristics with probing depth and bone loss around dental implants METHODS: A total of 642 implants in 145 subjects were followed up for a mean 6.4 years. At the last follow-up visit the subjects were examined clinically and radiographically to assess the status of peri-implant tissues and teeth. Data analysis used the generalized linear mixed models RESULTS: The prevalence of peri-implant mucositis and peri-implantitis were 82.1% and 41.4% at the subject level, and 68.4% and 22.7% at the implant level, respectively. Inadequate plaque control, peri-implant inflammation, history of previous implant failures, and pain/discomfort at the implant site were significantly associated with both outcomes (increased probing depth and bone loss). Diabetes mellitus, inadequate implant restoration, single restorations (versus multi-unit), cement-retained restorations, and presence of occlusal wear facets on teeth were significantly associated with one of the two outcomes. Implants placed in the lower anterior jaw region had the most favorable outcome. Smoking, history of periodontitis, and type of implant surface did not show significant associations with higher frequency of peri-implant diseases in the multivariable analysis. CONCLUSIONS: Peri-implant diseases are prevalent in this North African patient population. Multiple subject- and implant-level variables were associated with peri-implant diseases. Risk assessment of these effects should consist of a concurrent inclusion of these factors in multivariable analyses that also adjust for the complex variance structure of the oral environment.

Multidisciplinary Approach to Cover an Apex-Exposed Tooth: A Case Report after 6-Year Follow-Up.

INTRODUCTION: The prognosis for a successful treatment of gingival recessions (GRs) is one of the main criteria for deciding whether or not and how to perform root coverage surgery. The defect-related factors are the most important to predict root coverage outcomes. Thus, severe GR could make the root coverage (RC) challenging especially in cases with advanced interdental clinical attachment loss (ICAL). CASE PRESENTATION: This case report demonstrates a challenging management of a deep localized Miller Class III GR with root apex exposure associated with ICAL. After initial therapy, the treatment had consisted of a multidisciplinary approach involving endodontic treatment, periodontal plastic surgery including a laterally positioned flap, and orthodontic treatment. The 6-year follow-up showed improvement in clinical outcomes (recession reduction (RR) and keratinized tissue (KT) augmentation) and a higher patient satisfaction. CONCLUSIONS: This case report demonstrates the role of the multidisciplinary approach in the management of deep GRs associated with ICAL. A rational choice of the RC technique was critical to achieve good clinical outcomes.
