Periodontal disease is characterized by a loss of the connective tissue attachment induced by the presence of the dental plaque. The loss of periodontal tissue progresses in the apical direction, thus affecting all periodontal tissues. The primary etiology of periodontal diseases is the presence and maturation of a bacterial biofilm eliciting a host response (Socransky & Haffajee 2005). More specifically, in the posterior teeth, many factors play their role in affecting the onset and development of periodontal disease. Attachment loss in the furcation is one of the most serious anatomical sequels of periodontitis. What is worse, furcations are frequently not accessible for adequate professional debridement and home plaque control (Desanctis …show more content…
The specialist clinic in periodontics (SPA) is operated by specialist periodontists, post-graduate residents of clinical education in periodontics, dental hygienists, and dental assistants. All medical history, examination, diagnostic tests, results and treatments have been documented in the electronic central patients records (T4) and collateral paper files, which also include periodontal examination charts, conventional radiographs and supplementary health data generated by the governmental Primary Health Care Centers. A total of 1900 patients, whose histories were extracted from the electronic central patients records (T4) using the periodontal surgical codes, were explored. The total number of the patients received more than 4000 surgeries within the determined time frame (2004-2009). The extracted patients’ files were explored individually, and the patients who had received the specified surgical treatment, either tunnel preparation or root resection, were further
