PREVALENCE OF CERVICAL PATHOLOGY OF HARD DENTAL TISSUES AMONG YOUNG PEOPLE OF DONETSK REGION AND ITS RELATIONSHIP WITH MANIFESTATIONS OF PSYCHO-EMOTIONAL STRESS

Abstract

Purpose of the study. The analysis of frequency and distribution of cervical lesions of teeth in young people of Donetsk region, assessment of their connection with manifestations of psycho-emotional stress. Research methods. 272 patients (average age 24.3±6.9 years) were examined for the presence of cervical pathology of the teeth and parafunctional movements of the masticatory muscles, clinical symptoms of bruxism and TMJ musclearticular dysfunction, they were asked about complaints of frequent headaches and overfatigue. The level of personal anxiety was determined using Ch.D. Spielberger State- Trait-Anxiety-Inventory in the adaptation of Y.L. Khanina. Scientific novelty. Cervical lesions of the teeth were diagnosed in 43.4% of the examined, a significant part of which were wedge-shaped defects (in 60 patients) that in 8.3% of cases were associated with enamel erosions. Cervical pathology was more common on the lower jaw: caries – on the second premolars on the left, enamel erosion and a wedge-shaped defect – on the first molars and first premolars, respectively, equally often on both sides. The depth of wedge-shaped defects significantly increased (p<0.01) with age. A weak direct relationship between the occurrence of cervical caries and gender was determined (p=0.044). Weak direct correlation was observed between the presence of complaints of overfatigue and frequent headaches and the level of personal anxiety (p<0.005). A relatively strong direct relationship between headache complaints and the level of personal anxiety was found out (p=0.005) in patients with cervical caries. Among patients with a wedge-shaped defect biting and lip licking were significantly more common, with cervical caries – TMJ muscle-articular dysfunction and bruxism (p<0.05). A direct relationship between the pathology of TMJ and masticatory muscles and the level of personal anxiety, complaints of overfatigue, and the habit of tightly clenching the teeth was determined (p<0.05). There was weak direct correlation between the presence of enamel erosion and the parafunction of clenching the teeth tightly (p=0.031). A direct relationship was observed between the clinical symptoms of bruxism and the pathology of the masticatory muscles, the habits of clenching the teeth tightly and biting and licking the lips (p<0.05). Conclusions. It is recommended to consider the identified connections between cervical lesions of the teeth and manifestations of psycho-emotional stress when developing an individual approach to treatment and preventive measures.
