Abnormalities of microcirculation in dentoalveolar complex after direct occlusal restorations
Nowadays, the role of occlusion in etiology and pathogenesis of the inflammation in periodontal tissues have not still become clear and considered as biomechanics and articulation. Physiologically, masticatory pressure stimulates metabolic processes in periodontal tissues. Occlusal overloading leads to periodontal damages. The aim of this study is to reveal abnormalities of microcirculation in periodontal tissues and pulp after direct occlusal restorations. A total of 62 participants, 18–35 years old, with direct occlusal restorations were investigated. The functional analysis included the examination of diagnosis models in articulator PROTAR-evo VII and instrumental analysis with the use of ARCUS DIGMA system. The evaluation of microcirculation was made by the laser Doppler flowmetry (LDF).
RESULTS: The intensity of the periodontal tissues microcirculation in teeth with fillings on occlusal surfaces and teeth-antagonists significantly increases by 10–14% (p < 0.001). The intensity of a pulp microcirculation in the teeth with fillings on occlusal surfaces and teeth-antagonists significantly increases by 43–54% (p < 0.05). Thereby, in conditions of occlusal contacts abnormalities, reaction of microcirculation in periodontal tissues and pulp denote the chronic inflammation. At the initial stage clinical presentations are usually absent.
