Introduction: Treatment of destructive forms of chronic periodontitis is extremely topical. Its relevance is associated with the features of treatment, which depends on the stage of the exacerbation process. The issue of the problem is also in the fact that the destructive seat of periodontitis is a source of chronic infection. The aim: The task of the research was to evaluate the conservative treatment of chronic destructive forms of periodontitis with a dental kit “Cupratin”, developed for professional usage in dental practice. Materials and methods: “Cupratin” is a complex medicament based on suspensions of calcium hydroxide, copper-calcium hydroxide and powder, which contains hydroxide aluminosilicate and calcium sulphate, radiopaque filler. It has bactericidal and osteoplastic effect. The treatment involved 44 patients (44 teeth) in the age group of 37 to 50 years suffering from chronic granulating periodontitis without concomitant diseases. Patients were divided into two groups: investigated and control. In the main group of patients, a suspension on the basis of copper-calcium was used for treatment (root canals were filled with “Cupratin” as a temporary filling material). Obturation of canals was preceded by chemical and mechanical treatment. The medical material was in direct contact with periodontal tissues for 20-55 days. Intraoral X-ray radiography was taken from the patients within the intervals of 3 and 6 months. Results and conclusions: Positive results were obtained, which were characterized by the disappearance of subjective symptoms, intensive bone tissue reconstruction in the site of destruction and a decrease in the size of the destruction respectively.

The aim: To study the prevalence of odontoglyphic variants of the first permanent molars of the lower jaw in children 6-7 years old, as well as the frequency of caries lesions in molars with the most common types of patterns on their chewing surface. Materials and methods: We studied 1092 mandibular molars in 564 children without background pathology at the age of 6-7 years. The dynamics of the occurrence of fissure caries was studied in 347 first permanent molars of the lower jaw for 2 years and 246 molars in 155 children from among those observed during 3 years of the study. Results: In the children examined by us, the most common types of the chewing surface of the first permanent molars of the lower jaw were Y5- and + 5 patterns. We did not find a difference in the frequency of occurrence of these types in the surveyed girls and boys (p > 0.05). Our study showed that most often the first permanent molars of the lower jaw were affected by caries in the first 2 years of follow-up. The incidence of affection of the lower molars, which had a more complex structure of the occlusal surface (type Y5 and +5), was significantly higher than that of molars with the type of chewing surface +4. Conclusions: It has been established that in children 6-7 years old, the first permanent molars of the lower jaw have a more complex structure of the chewing surface, and the intensity of their caries damage is maximally high in the first two years after eruption and require active additional preventive measures in the early terms after their eruption.

Aim: To study the relationship between the psycho-emotional state of computer game players with the development of bruxism, its early diagnosis in people at risk, increasing the effectiveness of preventive measures in people with this pathology. materials and methods: At the first stage of the study, a survey of 120 people (85 - men, 35 - women) aged 18 - 30 years was conducted. The computer club was chosen as the place of the poll. The questionnaire is represented by questions that were aimed at identifying clinical manifestations of bruxism. Also, the subjects were asked to take an automated FPI test to assess the psycho-emotional state. In the second stage of the study, according to the results, the main group of patients with bruxism was identified. It consisted of 68 people aged 18-30 years (50 – men, 18 – women). The control group of people consisted of 20 volunteers (10 – women, 10 – men), who did not show clinical manifestations of bruxism and temporomandibular joint dysfunction and who do not play computer games. Results: According to a survey of 120 people aged 19-29, who often play computer games, it was found that 48.33% had bruxism. In 96.55% of the analysis of the FPI test revealed signs of mental distress. In the control group, the results of FPI in most indicators were average. Conclusions: The prevalence of bruxism among young people who play computer games was 48.33%, which is associated with psycho-emotional distress of this category of people: increased neuroticism, sudden aggression, depression, irritability and emotional lability. Diagnosis by questionnaire allows to detect manifestations of the disease in the early stages of development.
