Aim: The microbial differences between peri-implantitis and periodontitis in the same subjects were examined using 16S rRNA gene clone library analysis and real-time polymerase chain reaction.
Materials And Methods: Subgingival plaque samples were taken from the deepest pockets of peri-implantitis and periodontitis sites in six subjects. The prevalence of bacteria was analysed using a 16S rRNA gene clone library and real-time polymerase chain reaction.
Results: A total of 333 different taxa were identified from 799 sequenced clones; 231 (69%) were uncultivated phylotypes, of which 75 were novel. The numbers of bacterial taxa identified at the sites of peri-implantitis and periodontitis were 192 and 148 respectively. The microbial composition of peri-implantitis was more diverse when compared with that of periodontitis. Fusobacterium spp. and Streptococcus spp. were predominant in both peri-implantitis and periodontitis, while bacteria such as Parvimonas micra were only detected in peri-implantitis. The prevalence of periodontopathic bacteria was not high, while quantitative evaluation revealed that, in most cases, prevalence was higher at peri-implantitis sites than at periodontitis sites.
Conclusions: The biofilm in peri-implantitis showed a more complex microbial composition when compared with periodontitis. Common periodontopathic bacteria showed low prevalence, and several bacteria were identified as candidate pathogens in peri-implantitis.

Purpose: This retrospective clinical study aims to analyze single-unit implant-supported restorations' clinical and radiographic outcomes comprehensively.
Materials And Methods: In this retrospective study, patients who had undergone 12 months of implant-supported singleunit fixed prosthetic treatment were scanned from the archives, and a hundred patients were included in the study. Implant success and survival rates were assessed according to the consensus decisions published at the International Oral Implantology Congress in 2007.

Purpose: The available scientific evidence on the effectiveness of the surgical treatment of peri-implantitis is limited. The aim of this study was to assess the risk of recurrence or disease progression in patients with peri-implantitis that underwent surgical treatment.
Materials And Methods: A retrospective cohort study was carried out in patients subjected to peri-implant surgery between 2015 and 2021, and with a minimum follow-up of 12 months.

Objective: To evaluate the effects of tinidazole (TNZ) combined with minocycline (MINO) on therapeutic effectiveness, bone resorption, and inflammation in peri-implantitis (PI).
Methods: This retrospective study included 96 PI patients admitted between January 2023 and February 2024. Patients were divided into a control group (n = 46) treated with MINO and a research group (n = 50) treated with TNZ plus MINO.

Dental implants are now a standard solution for replacing missing teeth, even in patients with a history of chronic periodontitis. India is often referred to as the "diabetic capital of the world," a title that reflects the country's alarming rates of diabetes prevalence. However, the risk of complications, such as peri-implantitis and implant failure, remains a concern for these patients.

Background: To investigate the effect of rheumatoid arthritis (RA) on the incidence of peri-implantitis (PI) and peri-implant mucositis (PIM).
Methods: Radiographic and clinical chart reviews were conducted to measure the probing depth (PD), bleeding on probing, and marginal bone loss (MBL) around the implants to diagnose peri-implant diseases based on the 2017 workshop classification. Values were recorded at the baseline (T0) to the last available chart and radiograph (T1).
