Evaluation of Frontal Teeth Stabilization after Root Apex Resection among the Ukrainian Young People

Abstract

Objective: To develop a protocol of improved stabilization of teeth after root apex resection among young people using endodonto-endoossal implants and assessing its effectiveness. Material and Methods: Thirty-six patients were previously selected and divided into Group 1 (without additional stabilization) and Group 2 (with additional stabilization). The efficacy of treatment in both clinical groups was estimated at 90, 180 and 360 days, respectively. The results were evaluated on the Miller scale in the Flesrar modification. Density of bone tissue was expressed in Hounsfield units. Results: The average mobility indices over 90 days indicate a significant lower mobility of teeth in patients in Group 2, where as an advanced method, the RTR with an additional filling of the bone marrow defect with an osteoplastic material was chosen as the method of treatment (+ 18.0 ± 0.21 U.M. 10.0 ± 0.8 µm, p<0.05). In Group 1, 90 and 180 days after surgery, the density of bone tissue in the defect area was 756.3 ± 2.45 HU and 880.1 ± 4.34 HU. In Group 2, these indices were insignificantly higher and amounted to 834.3 ± 4.35 HU and 880.4 ± 2.56 HU. After 360 days after treatment in the first clinical group the bone density index was 957.4 ± 2.45 HU, while in the second group-1003.3 ± 4.38 HU. Conclusion: The mobility of teeth among patients on 90-th day corresponded to level 1, and on 360-th day corresponded to level 0, indicating the effectiveness of the proposed method. The biomechanical stabilization of the teeth was confirmed by the results of densitometry among patients of both groups, in particular, the recovery of bone density in the affected site was observed after 360 days.

Clinical Assessment of the Effectiveness of the Complex for the Prevention of Caries of Temporary Teeth in Children With Pathology of the Musculoskeletal System

“…the disease among children in Ukraine is high [1,2]. The incidence of caries of temporary teeth is especially high among children of preschool age with severe somatic pathology and in children who constantly live in conditions of deficiency of macro -and microelements and in ecologically unfavorable territories [3][4][5]. Numerous methods and means of local caries prevention have been implemented, which work effectively in healthy children [6][7][8][9].…”

“…Карієс зубів та його профілактика залишається актуальною проблемою сучасної стоматології, оскільки поширеність захворювання серед дитячого населення України є високою [1,2]. Особливо високою є ураженість карієсом тимчасових зубів серед дітей дошкільного віку при обтяженій соматичній патології та у дітей, що постійно проживають в умовах дефіциту макро-, мікроелементів і на екологічно несприятливих територіях [3][4][5]. Впроваджені численні методи та засоби місцевої профілактики карієсу, які ефективно працюють при застосуванні їх у здорових дітей [6][7][8][9].…”
