Clearer picture, according to the author, is defined in the distribution of dental calculus. In the group where the teeth cleaned regularly in the morning, dental Stone met much more often (69,76 ± 1,76%), than those who brushed their teeth at night (48,45 ± 6,24%). When two-time cleaning tartar identified only 30,76 ± 3,42% of cases. The differences are significant. Among the people cleaning their teeth regularly, dental Stone distributed 79,0 ± 1,41% of cases, and in the group studied who did not watch the state of the mouth, it is the most common (96,93 ± 2,26%).
These data are very strongly suggest that the presence of soft and calcified dental plaque depends more on the quality of hygienic oral care and teeth. We shall not consider other factors that contribute to the deposition of plaque (presence of dentofacial deformities, salivary flow rate, diet, metabolic disorders, etc.), they certainly deserve careful study and, of course, have great importance. We would like to emphasize that the feasibility of a regular, twice a day brushing is unquestionable, and the reality of the event, which has such a great preventive value, depends on competent health education promotion, regular tips on oral care. Latest must know and diligently every dentist. Great attention to oral health in this respect given to the other authors (Cohen, 1963; Bohannan et al., 1965; Gran, 1966, Emslie, 1967; Waerhaug, 1967; Swallow et al., 1969 V. Ivanov, and . I. Lasovsky, 1971 GN Paho-mov et al., 1971 VP Pakaln, GY Pakalns, 1971, etc.). Ironically, earlier in the mass screening does not take into account one very important factor — the abrasion of hard dental tissues, depending on the quality of care. Meanwhile, in the literature there are statements to the effect that regular care the teeth may lead to increased abrasion of tooth tissue (B. Dubrovin, 1927; Beckers, 1956; Gebhardt, 1958; Beyler, Mooser, 1960; Sumter, Blackburn, 1961; Schnell, 1971, etc.). However, conclusive evidence of harmful effects on teeth cleaning large clinical material, these authors do not. We decided to fill this gap and had a proper analysis of the available data. The studies found that increased abrasion of hard dental tissues (including the wedge-shaped defects) occur in persons who regularly cleaning your teeth, not more often than those who do it regularly or do not brush their teeth at all (see Fig. 9). In this vertical form abrasion, the most typical and likely trauma enamel brush and hygiene products, was detected in 12 (0.39%) from group of regular cleaning teeth, and in 11 (0.31%) patients out of no caring The oral, that is, in about equal proportions. Thus, the regular care the teeth in any way can not lead to increased abrasion of enamel and dentin. This conclusion is very important for the first time and is based on a large quite authentic and convincing to the survey. Therefore, the fear of some doctors about the possible impact of the toothbrush on the enamel are not justified and not justified. In addition, the irregular or poor care The oral leads to an increase in dental plaque, to an increase in periodontal disease, that is, poor oral hygiene contributes to dental disease and especially parodontopatiya (Fig. 12).
