Objectives: To assess the prevalence of peri-implantitis and identify risk and protective indicators of peri-implantitis in a population that underwent implant therapy in a university dental clinic. Method and materials: Randomly selected patients from a postgraduate university dental clinic were invited to participate. Clinical and radiographic examinations were recorded. Peri-implantitis was defined as the presence of bleeding and/or suppuration on probing, probing depths of >6 mm, and bone loss > 3 mm. Patient-, implant-, and bone-related factors were recorded and analyzed using a multivariate logistic regression analysis. Results: A total of 355 dental implants placed in 108 patients and exhibiting at least lyear loading time were included. The prevalence of peri-implantitis was 21.3% at patientlevel, while 10.7% at implant-level. Simultaneous guided bone regeneration (OR 2.76, 95% Cl 1.07-7.12, P = .O35), recurrent periodontitis (OR 3.11, 95% Cl 1.02-9.45, P= .045) and significant medical history (OR 2.86, 95% Cl 1.08-7.59, P = .034) were identified as risk indicators for peri-implantitis. The mean peri-implant bone loss was estimated to be 2.18 ± 1.57 mm for the total number of implants, whereas implants diagnosed with peri-implantitis demonstrated 4.42±1.12mm in a time period between 12 to 177 months. Conclusion: Within the limitations of the study, the prevalence of peri-implantitis in a cohort receiving dental implant therapy at a university dental clinic was 10.7% at implant level and 21.3% at patient level. Patient-reported systemic comorbidities and recurrent periodontitis as well as implants placed in ridge augmented sites were associated with greater risk of peri-implantitis. [ABSTRACT FROM AUTHOR]

Background: Ankyloglossia or tongue-tie is a congenital oral anomaly with short, tight, and thick lingual frenulum. It may be asymptomatic or can cause movement limitations of the tongue, speech and articulation difficulties, breastfeeding difficulties in neonates, as well as periodontal and malocclusion problems. The etiopathogenesis of ankyloglossia is unknown; it can occur either as a sole anomaly in the vast majority or in association with other craniofacial anomalies. Objectives: The aims of this paper were (1) to provide a comprehensive review on the criteria for clinical assessment and diagnosis, etiology and inheritance, and the therapeutic options of ankyloglossia; and (2) to demonstrate the treatment of ankyloglossia by means of frenuloplasty in three cases. Review: The available evidence from the literature indicates that among neonates, children, and adults the prevalence of ankyloglossia is low and in some cases remains undiagnosed. The early clinical assessment, diagnosis, and treatment are beneficial for the patients and their mothers. Conclusions: Frenuloplasty is a safe, quick, effective, and economical method and for this reason the parents should not hesitate towards frenulum release. More clinical studies are needed to confirm the benefits of the surgical interventions and to compare the results with those obtained using nonsurgical therapy or with untreated cases.

Objective To assess survival, as well as technical and biological complication rates of partial fixed dental prostheses ( FDPs) supported by implants and teeth. Method An electronic Medline search was conducted to identify articles, published in dental journals from January 1980 to August 2015, reporting on partial FDPs supported by implants and teeth. The search terms were categorized into four groups comprising the PICO question. Manual searches of published full-text articles and related reviews were also performed. Results The initial database search produced 3587 relevant titles. Three hundred and eighty-six articles were retrieved for abstract review, while 39 articles were selected for full-text review. A total of 10 studies were selected for inclusion. Overall survival rate for implants ranged between 90% and 100%, after follow-up periods with a mean range of 18-120 months. The survival of the abutment teeth was 94.1-100%, while the prostheses survival was 85-100% for the same time period. The most frequent complications were 'periapical lesions' (11.53%). The most frequent technical complication was 'porcelain occlusal fracture' (16.6%), followed by 'screw loosening' (15%). According to the meta-analysis, no intrusion was noted on the rigid connection group, while five teeth (8.19%) were intruded in the non-rigid connection group [95% CI (0.013-0.151)]. Conclusion The tooth-implant FDP seems to be a possible alternative to an implant-supported FDP. There is limited evidence that rigid connection between teeth and implants presents better results when compared with the non-rigid one. The major drawback of non-rigidly connected FDPs is tooth intrusion. [ABSTRACT FROM AUTHOR]
