Study of the Prevalence of Gingival Recession in the Tissues Arround Crowned Teeth in Patients of the Faculty of Dentistry of Tishreen University (Statistical, Classification and Therapeutic Study)

: The aim of this study was to investigate the role of crowning in the incidence of gingival recession around the crowned teeth. The study also aimed to verify the efficiency of some gingival surgical techniques in treating gingival recession as an alternative to replacing the fixed prosthesis. Moreover, the study opted to compare the percentage of the incidence of gingival recession around permanent prostheses in our society versus that in other societies. This study was conducted using 193 abutments distributed among 98 patients. In a special form per patient, the general and topical health conditions were recorded in addition to the status of the gingival tissue in general and around the prosthesis in particular. The percentage of the prevalence of gingival recession around fixed prosthesis was 31.1% (class 1 (23.3%), class 2 (7.3%), class 3 (0.5%) according to Miller). A total of 193 questionnaires were obtained that revealed the existence of a substantial relationship between the poor marginal adaptation of the crown and the gingival bleeding index and the degree of gingival recession. The results also revealed the lack of a significant relationship between the type of prosthesis used and the degree of gingival recession. Similarly, no significant relationship was noticed between the type of prosthesis used and the gingival bleeding index.
