Evaluation of Intermaxillary Fixation (IMF) Screw Therapy with Craniomandibular Index Analysis for Chronic Recurrent Dislocation in the Temporomandibular Joint.

BACKGROUND: Temporomandibular joint (TMJ) hypermobility is classified as a subluxation, complete (luxation), unilateral, or bilateral, acute, chronic protracted, or chronic recurrent dislocation. AIMS: This controlled randomized clinical study aims to evaluate the effectiveness of intermaxillary fixation (IMF) screw application and autologous blood injections in the treatment of chronic recurrent dislocation of TMJ in comparison with the placebo group. PATIENTS AND METHODS: The patients who were admitted to the Faculty of Dentistry of the Atatürk University between October 2018 and January 2020 were evaluated. Three hundred patients diagnosed with bilateral chronic recurrent dislocation of TMJ based on clinical findings and radiographs were included in the study. The patients were randomly divided into three groups according to the evaluation criteria. Group 1 received IMF, group 2 received autologous blood injection, and group 3 (placebo group) received an intraarticular saline injection. RESULTS: The results of the patients who received IMF, autologous blood injection, and saline injection were evaluated by the craniomandibular index. The IMF group showed significant improvement after 1 month and 6 months (P < 0.001), while the patients who received autologous blood injection and saline injection showed no significant improvement (P > 0.05). The data were analyzed with IBM SPSS V23. The significance level was P < 0.05. CONCLUSION: In our study, the IMF gave the best results among all the study groups. The IMF technique can be used in patients with protracted chronic recurrent dislocation in whom autologous blood injection has failed.

Benign tumors and tumor-like lesions of the oral cavity and jaws: An analysis of 709 cases.

PURPOSE: The purpose was to examine the prevalence, gender, age and site(s) of odontogenic and nonodontogenic benign tumors, and tumor-like lesions occurring in the oral cavity and jaws in a Turkish population, particularly, in the Eastern Turkey, and to compare findings of this study with other reports. MATERIALS AND METHODS: The data were collected from the files of the Department of Oral and Maxillofacial Surgery and the Department of Oral Pathology, Ataturk University, Turkey, during a 10-year period from January 2005 to January 2015. They were analyzed descriptively regarding prevalence, age, sex, lesion type, and site. RESULTS: A total of 709 benign tumor and tumor-like lesions of the oral cavity, and jaws were selected during a period of 10 years. One hundred and twenty-one of these lesions (17%) were odontogenic benign tumors while 588 (83%) were nonodontogenic benign tumor and tumor-like lesions. CONCLUSIONS: This study revealed that the distribution and characteristics of benign tumors and tumor-like lesions of oral cavity and jaws in the Turkish population, particularly including the Eastern region of Turkey have some differences as well as similarities with the findings of studies in different populations.

Odontogenic and nonodontogenic cysts: An analysis of 526 cases in Turkey.

PURPOSE: The aim of this study was to determine the age, gender, and sites of different types of odontogenic cysts (OCs) and non-OCs (nOCs) (seen in eastern Anatolian population in Turkey. MATERIALS AND METHODS: The following data were collected from the clinical records and histopathology reports of the Department of Oral and Maxillofacial Surgery and the Department of Oral Pathology, Ataturk University, Turkey, during a period of 10 years. They were analyzed descriptively in terms of incidence, age, sex, cyst type, and site. RESULTS: A total of 526 cysts were diagnosed during a 10-year period. Of these, 330 (62.7%) were in males, and 196 (37.3%) were in females, the male:female ratio was 1.7:1. There were 509 (96.8%) OCs and 17 (3.2%) nOCs. There were 406 (77.2%) inflammatory OCs and 103 (19.6%) developmental OCs. Radicular cysts were the most frequent (66.4%), followed by dentigerous (19.2%) and residual (10.8%) cysts. Only nasopalatine duct cyst was found as nOC in this study (3.2%). CONCLUSION: The distribution of jaw cysts in the Turkish Eastern Anatolian population is relatively similar to that of other populations reported in previous studies in the literature, in which most OCs were of inflammatory origin. However, the relative rates of cysts were higher than those reported in other studies.
