In vitro and in vivo methods of Raman spectroscopy have been developed to assess the degree of mineralization of the enamel of different functional groups. This article presents comparative studies that were carried out using scanning Raman microspectroscopy with various sources of laser excitation with wavelengths of 532, 785, and 1064 nm. It is shown that the intensity of Raman scattering of enamel can be a measure of its thickness. The obtained dependence of the Raman scattering intensity on the distance from the incisal edge is in good agreement with the literature data, where two independent methods (computer tomography and electron microscopy) are used to determine the enamel thickness values. The proposed methods can be considered as potential quantitative methods for express diagnostics of the state of tooth enamel in vivo.
Complications after implantation are noted at different follow-up periods [5, 6, 28, 33, 36, 38, 43]. It is known that the frequency of implant rejection varies, on average, from 3% to 35%, and an unoccupied inflammatory process leads to the loss of a dental implant [12].Currently, the development of peri-implantitis is more studied. However, as a result of clinical cases, the development of the inflammatory process from 6 months to 3 years after implantation was revealed. It has been established that during surgical procedures it is necessary to carry out a complex of prophylactic measures that make it possible to prevent the possibilities of inflammation developing [32].Reasonable and clinical application of the treatment-and-prophylactic rehabilitation complex in patients, taking into account individual characteristics in each clinical case, is relevant. So, the task of developing and justifying a complex of therapeutic measures, which allows to obtain a large number of complications during dental implantation, is not only medical, but also social.
Обоснование. Ведущее место среди осложнений, связанных с операцией удаления зуба, в настоящее время продолжают занимать альвеолит и ограниченный остеомиелит челюстей. Цель исследования-изучить антибактериальную и клиническую эффективность применения озонотерапии и светодиодного излучения различных длин волн при альвеолите и ограниченном остеомиелите челюстей для повышения эффективности лечения и сокращения сроков реабилитации. Материал и методы. Было проведено обследование и лечение 100 пациентов с альвеолитом и ограниченным остеомиелитом челюстей в возрасте от 18 до 65 лет. Все больные были разделены на четыре равные группы: 1-ю группу составили пациенты, в комплекс лечебных мероприятий которых был включен курс озонотерапии и светодиодного облучения красным светом (630 нм); во 2-й группе использовали озонотерапию в сочетании со светодиодным излучением зеленого света (530 нм); в 3-й группе применяли озонотерапию и светодиодное излучение синего света (470 нм); в 4-й (контрольной) группе в комплекс лечебных мероприятий физиотерапию не включали. Для изучения влияния озонотерапии и светодиодного излучения различных длин волн на микрофлору лунки удаленного зуба бактериологическое исследование проводили трижды: до лечебных воздействий, через 3 и 5 дней после терапии. Результаты. Для лечения альвеолита предпочтительнее назначение озонотерапии и красного света (630 нм), а при ограниченном остеомиелите челюсти-озонотерапии и синего света (470 нм). Заключение. Полученные результаты очень важны для представленной группы обследованных пациентов, так как происходит значительное сокращение сроков их реабилитации.
The study is devoted to the study of the effect of water ozonated with the help of short-wave ultraviolet radiation, used in the removal of dental plaque and hydromassage of the gums, on the microbiota of periodontal pockets.Examination and treatment of 102 patients aged 35–55 years with a diagnosis of chronic generalized periodontitis of moderate severity was carried out. The results of microbiological studies indicate the high efficiency of the removal of dental plaque using water ozonated with short-wave ultraviolet radiation and hydromassage of the gums in the complex treatment of chronic generalized periodontitis of moderate severity. The study of the microbiota of periodontal pockets after the use of ozonized water showed a significant decrease in the frequency of detection of representatives of anaerobic periodontopathogens, with an increase in the sowing of species of stabilizing microbiota.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
