Functional status of pulp vessels in case of hard dental tissues preparation for metal ceramic crowns. Results of the study

: Rheodentography (RDG) was used for the study of functional status (vasodilatation or vasoconstriction) of pulp vessels before and after making preparation of hard dental tissues of different volumes as the treatment of partial loss of teeth with metal ceramic crowns. 57 patients were divided into 2 groups--with reduced tone of peripheral vessels (27.2% of the all examined patients) and increased tone of peripheral vessels (72.8%). RDG was registered before the teeth preparation, during 1st week after preparation and also 2, 3 and 4 weeks after preparation when the regular stage of metal ceramic construction making was delivered. All in all 228 RDG were registered, they were estimated visually and quantitatively by amplitude-temporal indices. Differentiated approach was recommended to prosthetic treatment of partial loss of teeth with the help of metal ceramic constructions, demanding deep preparation of hard dental tissues in patients with clinically healthy periodontal tissues having reduced and increased tones of peripheral vessels and in patients with parodontitis.
