Prevalence of Peri-Implantitis and Peri-Implant Mucositis among Implant Patients: A Dental University Based Study.

Abstract

The term peri-implantitis describes an inflammatory disease that results in the loss of supporting bone around an implant. It differs from mucositis in which the inflammation of mucosa surrounding an implant is not accompanied by bone loss and is reversible. Peri-implant diseases are not uncommon following implant therapy. This study aims to find the incidence of peri-implantitis and peri-implant mucositis among patients having undergone implant therapy in dental university hospital in Chennai, India. A retrospective cross-sectional study was conducted using 305 samples from the Department of Implantology after reviewing and analyzing the data of 86,000 patients between June 2019 and March 2020. Microsoft Excel® was used to tabulate the data obtained. The variables assessed were age, gender, presence of infection, type of inflammation, and site of implant placement. The sample had a gender distribution of 60.33% males and 39.67% females. Forty-one percent of implant patients belonged to the age group of 36-55 years. The most (27.5%) common site of implant placement was sextant 4 specifically in relation to the first molar; 98.69% of implant sites showed no signs of infection; 0.66% of implants (in one subject) showed peri-implantitis; 0.33% showed peri-implant mucositis; and for 0.33% of implants the data was insufficient for categorization. Within the limits of the study, the incidence of peri-implantitis and peri-implant mucositis was 1.31% among implant patients of a dental university hospital in Chennai, India.
