[Architecture of the mandibular alveolar process in the hamster. Influence on the localization and morphology of periodontal lesions].
The influence of the anatomical characters of the alveolar processes on the morphology of bone destruction during the development of periodontitis seemed to be very important in Man. The purpose of the present study is to check such an association in hamster, experimental model used in periodontal research. A macroscopic study of mandibular alveolar processes of hamsters with periodontal diseases has shown that the destruction aspects of the alveolar processes had constant features, despite variability in the importance of bone destruction aspects of the alveolar processes had constant features, despite variability in the importance of bone destruction between animals: -- the lingual zone of m1 was most affected, -- the alveolar bone destruction was more important on the lingual face than on the buccal face, -- intra-bony lesions developed along a buccal gutter extending from the distal root of m1 to the mesial root of m3. The morphology of these bone destructions corresponded to anatomical features, the most striking being: -- the bone wall surrounding the mesial root of m1, where a dehiscence was present, was extremely thin,-- the lingual bone plate was uniformly this despite localized reliefs which thickened it in places, -- the buccal bone plate was widened by a cervical gutter. It appeared therefore that the localisation and morphology of the periodontal bone lesions in the hamster are related to the anatomy of the alveolar processes.
