ABSTRACT
Periodontal diseases are inflammatory lesions initiated by oral bacteria and lead to the destruction of the supporting structures of the teeth (gingiva, periodontal ligament and alveolar bone) in susceptible patient. Via several biological mechanisms, periodontal diseases have been associated with multiple systemic diseases, such as rheumatoid arthritis, diabetes, cardiovascular diseases, Alzheimer's disease and adverse pregnancy outcomes. Similarly certain eye diseases have been associated with systemic diseases of the inflammatory pathway. We hypothesized that periodontal diseases are associated with eye diseases. Thus using literature data we find that several studies have reported that eye disorders are associated with the presence of periodontal diseases. But the mechanisms of this relationship are not clear. However the innate immune response involvement, the sharing of similar risk factors in pathogenesis and the changes of eye choroid thickness may be suggested as several hypotheses to explain this potential association.

BACKGROUND: The confection of a fixed prosthesis finds its indication in response to the patient's aesthetic and/or functional whose requirements are stronger in terms of satisfaction. This involves maintaining the stability of prosthetic reconstructions on a sufficiency long time. To achieve this, the preservation of periodontal health of the prosthetic abutments occupies a special choice. PURPOSE: The aim of this study was to evaluate the periodontal health of fixed prosthesis abutment. MATERIALS AND METHODS: Thirty-nine patients having fixed prosthesis in the mouth for more than one year participated in our study. Ultimately, 38 single crowns and 27 seven bridges based on 100 abutments have been recorded. After an interview, clinical and radiographic examination was performed. It was to assess the level of oral hygiene, the health of the superficial and deep periodontal abutment using OHIS index of Green and Vermilion, periodontal index of Russel and mobility index of Mühlemann. RESULTS: On the 100 abutments examined, gingivitis (14%), gingival recession (13%), bone osteolysis (29%) and mobility (5%) were recorded. In addition, about 60% of patients had inadequate oral hygiene and less than 30% of them had a regular prosthetic maintenance. CONCLUSION: From this study, it appears that complications affecting periodontal prosthetic abutments are essentially bone lysed (29%), gingivitis (14%) and gingival recessions (13%).
