EFFICACY OF ARTHROCENTESIS FOR TREATMENT OF INTERNAL POST-TRAUMATIC TEMPOROMANDIBULAR JOINT DISORDERS.

OBJECTIVE: The aim: To study the consequences of temporomandibular joint injury and efficacy of arthrocentesis for treatment of post-traumatic internal temporoman-dibular disorders. PATIENTS AND METHODS: Materials and methods: 24 patients who experienced trauma history in the head without jaw fractures underwent CT, ultrasound and/or MRI. TMJ ar¬throcentesis was performed according to a modified method of D. Nitzan (1991) under local anesthesia by means of blockade of the peripheral branch of the auricular-temporal nerve on the background of intravenous sedation. RESULTS: Results: The ages of the patients varied between 18 and 44 years, and mean was 32,58 years. The causes of trauma were diverse, as traffic accident - 3 (12,5%), assault 12 (50%), hit by materials 3 (12, 5%), and fall-down 6 (25%). According to clinical and radiological signs after traumatic temporomandibular disorders, patients were divided into two groups according to Wilkes classification (1989): 13 patients with stage II (early-middle) and 11 - with stage III (middle).The control ultrasound and MRI carried out 3-6 months after arthrocentesis showed no signs of hemarthrosis in 84.61% of patients with intra-articular disorders of the second degree, and in 72.72% of patients with internal disorders of the third degree, the position and function of the articular disc was restored. CONCLUSION: Conclusions: Arthrocentesis with TMJ lavage is a minimally invasive surgical manipulation that has proven itself in temporomandibular disorders of traumatic origin, in particular after fractures of the articular process of the mandible.

Assessment of oral hygiene maintenance in 12-18-year-old children and teenagers with fixed orthodontic appliances.

BACKGROUND: Good oral hygiene is very important to ensure successful orthodontic treatment. Orthodontic treatments may cause plaque accumulation and in this way the development of caries and periodontal diseases which are basically caused by dental plaque. The aim of this study was to compare the features of oral hygiene among different age groups and genders in patients with fixed orthodontic appliances. MATERIAL AND METHODS: The study involves 118 patients aged 12 to 18 (64 males (54.2%) and 54 females (45.8%)) with fixed orthodontic appliances from the Department of Orthodontics at Danylo Halytskiy Lviv National Medical University. The patients completed the questionnaires which included 19 questions about their oral hygiene. RESULTS: It was revealed that 59 females (92.19±3.35%) believe that oral hygiene is important, but among the males number of such persons have been significantly lower - 41 (75.93±5.82%), p<0.05. Statistically significant result was obtained showing that females (46 patients (71.88±5.62%) use interdental brushes more regular (every day) than males (26 (48.15±6.80%), p<0.05. Comparing the differences between the regularity of teeth brushing in different age groups showed that 53 patients (82.81±4.72%) aged 12 to 15 and 46 (85.19±4.83%) aged 16 to 18 claimed that they brush their teeth regularly, twice a day, 8 (12.50±4.13%) and 6 (11.11±4.28%), respectively - once a day. CONCLUSION: In patients with fixed orthodontic appliances oral hygiene of 16-18-year-old respondents is better than the oral hygiene of 12-15-year-old ones.
