A side property in the teeth and periodontium condition in big city residents discovered during epidemiological study according to visual and instrumental examination

Relevance. Effective preventive programs cannot be developed without studying the issue using population epidemiological survey. Purpose – improving efficiency of dental diseases prevention basing on the information obtained during an epidemiological survey of Izhevsk citizens.

Materials and methods. Visual and instrumental examination of teeth and periodontium was performed in 107 residents according to WHO criteria in representative age categories: n = 57 (63.3%) in the category from 35 to 44 years old; n = 50 (46.7%) - from 65 to 88 years; n = 83 (77.6%) women (54.9 ± 1.9 years); n = 24 (22.4%) men (53.7 ± 3.7 years). The study was random and voluntary, the conclusions are based on the results of statistical analysis.

Results. Examination revealed that most of the intact teeth were located on the left side (n = 617; 51.0%) of the jaws. Examination confirmed the hypothesis that on the opposite side hygienically caused diseases of the teeth and gums should prevail. On the right side of the jaw carious teeth (n = 91; 53.2%), secondary absence of teeth (n = 482; 53.2%), bleeding gums (n = 166; 51.9%), pathological gingival pockets (n = 178; 59.5%) were more common. The observations complex (n = 49) showed significantly more often (p <0.01) priority of the right side (n = 31; 62.0%).

Conclusion. The detected side property is not accidental. It occurs due to the varying effectiveness of individual hygiene. Most people are right-handed and the right side of their jaw requires more complex movements from their right hand. Permanent hygiene defects slowly turn into an additional cariogenic and periodonto pathogenic factor. The authors believe that informing right-handed (or left-handed by analogy) people about the need to control movements of their hand will help to balance the quality of hygiene on both sides of the jaws and make the teeth and periodontium diseases more rare.
