ANALYSIS OF THE RESULTS OF TREATMENT OF DESTRUCTIVE FORMS OF APICAL PERIODONTITIS WITH OSTEOTROPIC DRUGS IN A SHORT TERM.

OBJECTIVE: The aim: The aim of the study was to evaluate the effectiveness of osteotropic drugs in the treatment of destructive forms of apical periodontitis. PATIENTS AND METHODS: Materials and methods: The study was conducted at Danylo Halytsky Lviv National Medical University, Department of Therapeutic Dentistry, Lviv, Ukraine. As a result of the research, 185 patients with destructive forms of apical periodontitis (DFAP) were examined and treated. To characterize the effectiveness of treatment using criteria based on the provisions of the European Society of Endodontology. Thermometric studies of the oral mucosa were performed according to the method of L.Ye. Smolyanko and A.V. Lysovogo. RESULTS: Results: After 3 months, 145 treated patients (78.38%) out of the total number of subjects belonged to the 3rd category ("failure"). At the same time, this category included the largest share of patients of groups I and II of the study - 95.67% and 95.56%, respectively. In 70.21% of patients of group III, with transferred outside the apex PRP, and in 53.19% of persons of group IV, with the use of the composition «PRP + mp3 OsteoBiol¼ there were no clinical signs of DFAP. It was noted that 22 (46.81%) and 14 (29.79%) patients groups III and IV had no clinical signs of DFAP and radiologically determined a decrease in the focus of bone destruction of the periapical area, which allowed them to be classified as 2 - category of success - «incomplete recovery¼. CONCLUSION: Conclusions: The results of the research convincingly testify to the effectiveness of our proposed therapy for the treatment of dystrophic forms of apical periodontitis.

Determining the frequency of functional disorders of the TMJ in patients with mandible fractures depending on the location.

OBJECTIVE: The aim: To investigate the frequency of functional TMJ disorders in patients with fractures of the mandible. PATIENTS AND METHODS: Materials and methods: To achieve this goal, 111 patients hospitalized in the department of surgical dentistry of the Chernivtsi Regional Clinical Hospital were examined for traumatic fractures of the mandible with functional disorders of the TMJ (occlusive, muscular, articular disorders). The examination of patients with functional disorders wasbased on Express - the conclusion of the Hamburg Protocol: 1. pain in palpation of joints; 2. pain in palpation of chewing muscles; 3. presence of noises in the joints; 4. violation of the opening trajectory; 5. the opening of the mouth is limited; 6. eccentric occlusion, premature contacts. Statistical processing of research results was carried out using commonly used methods of variation statistics. RESULTS: Results: We found that on average, mandibule fractures showed the highest number of single-function occlusion`s (18.92%) and articular disorders (21.62%) and multifunctional occlusal-articular disorders (20.72%), with the smallest the frequency of one-function muscle`s disorders (4.50%). Multifunctional TMJ disorders «occlusal + muscle¼ and «muscular-articular¼ in this contingent of patients were determined, on average, at the same percentages (10.81%). Attention was drawn to the fact that «muscular + articular¼ dysfunction of the TMJ was diagnosed more frequently with the immobilization of the fragment with the help of osteosynthesis (18,18 ± 4,54%) and with the combined method (15,39 ± 3,84%) than when both jaws are splinted, p <0,05. CONCLUSION: Conclusions: It was established that in patients with fractures of the jaws of different localization single-functional articular disorders (21.62% of the subjects) and multifunctional «occlusion-articular¼ disorders (20.72% of the examined) predominated. In this case, the frequency of TMJ dysfunction, to a large extent, depended on the nature of the displacement and the way of immobilization of the fragments of the mandible.

Prevalence of the generalized periodontitis in patients with different groups blood in depending on age and periodontal biotype.

OBJECTIVE: The aim of the study was to investigate the prevalence of generalized periodontitis depending on age and biotype of periodontium. PATIENTS AND METHODS: Materials and methods: We examined 855 males aged 20-55 years, who were divided into 2 groups: the main group - 570 surveyed with a generalized periodontitis, the comparison group - 285 dental healthy individuals.The diagnosis of generalized periodontitis was established by the classification Danilevsky M.F. (1994) and refined by using paraclinical indices. The periodontal biotype was determined using Hu-Friedy Colourvue Biotype Probe. RESULTS: Results: As a result of the conducted researches was establish, in the carriers of blood group O (I) and A (II), developed forms of generalized periodontitis were found, on average, 2.7 times more often than the initial forms of the disease. Instead, at the representatives of B (III) and AB (IV) groups blood the frequency of initial GP - I degree was on average, 1.2 times greater than the prevalence of developed forms of generalized periodontitis. Also as a result of our researches, we found that the cluster A1 had 39.30% patients, cluster A2 was found at 28, 77%, and cluster B - 31.93% of the total number of patients with generalized periodontitis. CONCLUSION: Conclusions: As a result of our research, it was found that in the carriers of the blood group O (I) and A (II), more advanced forms of generalized periodontitis were observed, which was confirmed by the presence of the biotype of the periodontal disease in the cluster A1 and A2.
