This article describes the assessment of the condition, symmetry of temporomandibular joint and timely diagnosis of its dysfunction based on to H. Gelb method in malocclusion. The objective of this study was to investigate the position and assess the symmetry of the temporomandibular joint heads according to H. Gelb in cases of malocclusion. Materials and мethods. The study was based on analysis of computed tomographs of 70 patients with malocclusion. Depending on the stage of the occlusion development, the patients were divided into two groups: I group included 30 patients with mixed dentition and II group included 40 patients with permanent dentition. Results. The results obtained demonstrated that regardless of the pathology of the occlusion and age, only 8 patients had the correct bite, i.e. the symmetrical position of the temporomandibular joint heads in the Gelb 4/7 position. The most frequent symmetric position of the articular heads in the patients of the I group I was the Gelb ¼ position found in 16 patients; the Gelb 1/5 position was revealed in 8 patients of the II group that can be explained as age-related changes in the displacement of the articular heads from the Gelb 1/4 to 1/5 position. Conclusions. According to the results of our research, it was found that regardless of the malocclusion and age, patients who have the correct position of the temporomandibular joint heads on the left and right in the Gelb 4/7 position make up only 10.52%. The age-related dynamics of the rotational displacement of the centre of the articular heads from the Gelb 1/4 to 1/5 position has been observed, and the number of patients with the asymmetric position of the temporomandibular joint articular heads is increaing.

Temporomandibular Joint Osteoarthritis

Background and objectives: There is an increasing number of patients applying for dental treatment who suffer from temporomandibular joint osteoarthritis (TMJOA). Osteoarthritis may be the cause of the pain in the area of temporomandibular joints, but its course may also be absolutely asymptomatic. The aim of this study was to present an interdisciplinary approach to TMJOA, including current diagnostics and treatment modalities on the basis of the available literature. Materials and Methods: PubMed and Scopus databases were analyzed using the keywords: ((temporomandibular joint AND osteoarthritis) AND imaging) and ((temporomandibular joint AND osteoarthritis) AND treatment). The bibliography was supplemented with books related to the temporomandibular joint. After screening 2450 results, the work was based in total on 98 publications. Results and Conclusions: Osteoarthritis is an inflammatory, age-related, chronic and progressive degenerative joint disease. Magnetic resonance imaging (MRI) and cone-beam computed tomography (CBCT), together with clinical symptoms, play significant roles in TMJOA diagnosis. Current MRI techniques seem to be clinically useful for assessment of bony changes in temporomandibular joint (TMJ) disorders. Treatment of TMJOA requires a complex, interdisciplinary approach. TMJOA treatment includes the cooperation of physiotherapists, rheumatologists, gnathologists, orthodontists and quite often also maxillofacial surgeons and prosthodontists. Sometimes additional pharmacotherapy is indicated. Thorough examination of TMJ function and morphology is necessary at the beginning of any orthodontic or dental treatment. Undiagnosed TMJ dysfunction may cause further problems with the entire masticatory system, including joints, muscles and teeth.

This study evaluated age-related changes in the gross morphology and morphometry of the testis and epididymis of the African Greater Cane Rat (AGCR). Twenty pathogen-free cane rats used for this study were randomly divided into 4 groups; Group I - prepubertal (≤4 months), Group II - pubertal (>4≤12 months), Group III - adult (>12≤30 months), and Group IV - aged (>30 months) of 5 animals each. On day 8th of acclimatization, testis and epididymis were harvested from sedated cane rat, described grossly and standard morphometric parameters (length, width, circumference, weight, and relative weight) determined. Gross morphological observations in the testes of all the different age categories showed similar characteristically cream to milky-white coloration and ellipsoidal shape. The epididymis in the different AGCR group uniquely presents the same inverted S-shaped outline, loose attachment to the testis, and less distinct division into caput, corpus, and cauda segments. Testicular and epididymal morphometric parameters were significantly reduced in the prepubertal cane rat relative to other groups. The parameters consistently displayed an age-dependent increment with the advancing age of the animal. In conclusion, this study has shown that both testicular and epididymal gross morphometrics increase with age advancement and perhaps might be linked to the varying functional reproductive status of the different age groups of the African greater cane rat.
