[Bioethics in orthodontics].

The objective of the study was to reveal the necessity of implementation of bioethical principles in the treatment of patients with dentofacial anomalies. Scientific publications revealing the interrelation of basic bioethical principles and characteristics relevant during treatment of patients with dentofacial anomalies were monitored and analyzed. The patient's responsibility for the results of treatment, the revision of life values, the change of overall lifestyle contributes to the patient's recovery. An orthodontist must follow basic bioethical principles: benevolence, autonomy, causing no harm, and justice. Trust-based relations in the system "doctor-patient" allow the doctor to share the knowledge which contribute to the patient's recovery, so the necessity of implementation of bioethical principles (benevolence, autonomy, causing no harm, and justice) in the treatment of patients with dentofacial anomalies was revealed.

[The impact of internal TMJ disorders on quality of life of patients with malocclusion].

Articular disturbances of temporo-mandibular joint (TMJ) combined with dentofacial anomalies (DFA) decrease the quality of life. The objective of the study was ti determine dental quality of life in patients with "internal disturbances" of TMJ combined with DFA. Questionnaire survey (Oral Health Impact Profile OHIP-14-RU) of 96 young patients was carried out. The patients were treated due to DFA combined with "internal disturbances" of TMJ. It should be pointed out that patients with hyperdivergent skeletal pattern have the most evident trend towards setting the quality of life to zero in dental sphere. Moreover, the trend is more evident in the case of patients with dento-alveolar types of occlusion anomalies. Patients with dento-alveolar type of open occlusion have maximum points in "Psychological discomfort", "Psychological disability", and "Social disability". Patients with distal occlusion and hyperdivergence of jaw bones have maximum points in "Psychological disability" and "Social incapacity". Patients with the combination of distal occlusion and deep incisal occlusion have maximum points in "Psychological discomfort" and "Social disability". Patients with "internal disturbances" of TMJ combined with DFA reveal a negative shift of questionnaire information. The maximal rates were revealed in "Psychological disability" and "Social disability", the minimal ones--in "Functional limitation" and "Handicap".

[Interrelationship wisdom teeth dystopia and internal TMJ disorders: a clinical case].

The patient with painful restriction of jaw movements showed CT and MRI of TMJ signs of on-reducing disk displacement of the right TMJ and secondary arthrosis. Signs of occlusion obstacle and compression of the right TMJ structures have been revealed by studying of diagnostic models, MPI, investigation of TMJ with KAVO Arcus Digma II system. The etiological factor proved to be th dystopia of 4.8. Complete recovery of the TMJ function has been noted after removal of tooth 4.8. CT and MRI of TMJ, investigation of occlusion are indicated for patients with non-reducing disk displacement of TMJ. Malposition of third molar can lead to development of internal derangements of TMJ.
