The Prevalence and Intensity of Dental Diseases Among Workers with Dangerous Working Conditions, Depending on the Presence or Absence of Previous Oral Sanitation

   Relevance: to substantiate programs for the prevention of dental diseases at nuclear industry enterprises with dangerous working conditions, comparative studies of the dental status of employees, depending on the presence or absence of previous oral sanitation, are relevant.

   The purpose of the study: clinical and radiological comparison of indicators of the dental status of nuclear power plant workers with hazardous working conditions (OT), depending on the presence or absence of previous oral sanitation.

   Materials and methods: 78 employees of the Kalinin nuclear power plant with dangerous working conditions in the key age group of 35–44 years, who underwent therapeutic and surgical sanitation of the oral cavity a year ago, were examined. For comparison, 69 workers with OT of an identical gender and age group who refused to sanitize the oral cavity during periodic medical examinations were examined. The sequence of clinical and radiological examination corresponded to the modified WHO Dental Status Assessment Map (1995).

   Results: the positive effect of oral sanitation due to the removal of destroyed teeth, treatment of caries and its complications, as well as periodontal diseases is to reduce the prevalence of signs of dysfunction of the temporomandibular joint by 52.5 %, non-carious offspring 22.7 %, diseases of the oral mucosa 24.1 %, periodontal diseases 6.0 %. As a result of sanitation, the detection of poor oral hygiene is reduced by 54.7 %. The intensity of caries and periodontal diseases a year after sanitation is 12.8 and 27.8 % lower in comparison with workers with an unsanitized oral cavity. After rehabilitation, the prevalence of orthopedic treatment increases by 43.4 %.

   Conclusions: oral sanitation significantly improves the basic indicators of dental status for workers with dangerous working conditions at nuclear power plants. The positive effect of oral sanitation is largely preserved after a year in comparison with non-sanitized workers. Oral sanitation at the age of 35–44 years does not affect the prevalence of caries.
