ABSTRACT
@#Periodontal disease is individual-specific and site-specific. Therefore, the periodontal sequence treatment plan should not only base on the patient's condition and disease progression, but also take local conditions into account. This paper reports the whole periodontal therapy of a young patient with stage Ⅳ grade C generalized periodontitis with longitude observation of 7 years. We analyze the factors between extraction and maintenance of hopeless teeth from individual-specific and site-specific perspectives. We also discuss the importance of keratinized mucosa around implants in order to provide reference for the treatment of periodontitis.
ABSTRACT
@#Periodontitis is an inflammation that occurs in the supporting tissues around teeth with plaque biofilm as the starting factor. Periodontitis is closely related to many systemic diseases, among which the relationship between periodontitis and diabetes is the most widely reported. A cohort study is an essential clinical research method to explore the etiology. Large, well-conducted prospective cohort studies have high power, which can provide important clinical evidence for the impact of periodontitis on blood sugar control, incidence rate and complications of diabetes mellitus. Periodontitis is associated with the deterioration of glycemic control. At present, there is moderate evidence that nonsurgical periodontal treatment can significantly improve the blood sugar level of diabetes patients with periodontitis compared with no periodontal treatment. Studies on the impact of periodontitis on the incidence rate of diabetes lack consistent conclusions because of different population backgrounds. The evidence regarding whether periodontitis affects the incidence rate of diabetes complications is relatively limited. Therefore, well-designed cohort studies are needed to provide high-quality clinical evidence.
