Prospects for the use of terahertz therapy in dental implantation in conditions of chronic tobacco intoxication (an experimental study)

Objective: to determine the features of peri-implant tissues healing in conditions of tobacco intoxication and the possibility of their correction by using electromagnetic terahertz radiation at the frequency (EMR THF) of 129.0 GHz. Material and Methods. 36 rabbits were divided into control group and three experimental ones. In the experimental groups, tobacco intoxication was simulated for 6 weeks, then implantation was performed and tobacco intoxication was maintained until the end of the experiment. In the 1st experimental group, physiotherapy was not performed; in the 2nd and 3rd groups, various schemes of THF therapy were used. The results were evaluated using histological methods. Results. In the control group, the most active regeneration processes were noted. Among the experimental groups, the best indicators were achieved in the groups where THF radiation was used. The thickness of the connective tissue layer after 1 month was significantly lower in the 2nd and 3rd groups, amounting to 48.0±3.9 and 42.7±3.4 urn, respectively, than in the 1st group: 76.4±3.5 urn (p
