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

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.

Oral Health-Related Quality of Life among Implant-Supported Full-Mouth Rehabilitation Patients Treated in a University Dental Hospital - A Retrospective Study.

Full-mouth rehabilitation is the restoration of the form and function of the masticatory apparatus. Complete dentistry has five comprehensive goals in full-mouth rehabilitation: anatomic harmony, optimal oral health, best aesthetics, occlusal stability, and functional harmony. Oral health-related quality of life (OHRQoL) has become an important issue in the clinical practice of dentistry. Loss of complete natural teeth and resorption of alveolar bone are considered oral health impairment because they hinder the mastication, phonetics, and aesthetics of the stomatognathic system. A questionnaire was prepared regarding the oral health-related quality of life of implant-supported full-mouth rehabilitation patients, using 2,637 patient records first identified and analyzed according to specific inclusion criteria. Patients who did not fulfill the criteria were not included. Seven patient records were finalized and a telephonic conversation was held to administer the questionnaire. The results obtained were first categorized and analyzed via SPSS as follows: age: 46-60 years; gender: males (57.1%), females (42.9%); difficulties in food chewing: yes (28.6%), no (57.1%), sometimes (14.3%); crown fitting: yes (14.3%), no (85.7%); pain in tissue while masticating: sometimes (14.3%), never (85.7%); self-conscious: yes (57.1%), no (71.4%); changes from natural tooth: yes (28.6%), no (71.4%); difficulties compared with natural teeth: chewing difficult (14.3%), pain (14.3%), no difficulties (71.4%). Within the limits of the study, it was seen that patients with implant-supported full-mouth rehabilitation have improved appearance, better satisfaction, and higher quality of life.
