A weak link of dentistry is the lack nurses, their special knowledge and skills. It leads to an irrational use if a dentist’s labour. A need for a special training of specialists with secondary medical education, including «dental assistant» arises (V.V. Sadovskiy, V.I. Starodubov, A.A. Kalinskaya, and others, 2006).

As an experiment, we have approbated an organization-functional model of a doctor’s work and a dental assistant that includes: work algorithm, setting realized volumes and labour costs of the dentist and his dental assistant in four hands, normalization of work of these specialists.

During the research we have taken work normalization of a dental therapeutist and dental assistant in four hands according to the recommendations of Scientific-research center of N.A. Semashko (V.M. Shipova and others, 1987).

Chronometric estimations of work time costs of the dentist and dental assistant have been analyzed by separate work operations that were differentiated depending on a diagnosis, number of tooth roots, number of visits, and also types of activity of the dentist and his dental assistant in terms of work with four hands.

Table 1 provides the structure of work time costs of the dentist and dental assistant in terms of work with four hands.

Research materials testify for a relative load of the doctor and his dental assistant with treatment-diagnostic work of 84,4 and 91,5 % of the time.

We should outline that time costs of the doctor and dental assistant for work with medical documents are small, and it is linked to the fact that passport part of a patient’s medical card was filled by registry of the clinic Tooth formula in the medical card of a patient, the list of everyday work of the dentist was filled by the dental assistant. The doctor only filled the fields of medical card that relate to the diagnostic and treatment of a patient.

Average time costs of dental assistant per a visit, considering coefficient of repeat, equaled 46,4 minutes (Table 2). Time costs of the dentist and dental assistant in terms of work with four hands are provided in Table 3.

The received average time costs of the dentist and his dental assistant per a visit were taken as a basis to define a volume of specialists’ work load during a day. According to labour law (resolution of the Government № 101 of 14.02.2003 «On the duration of work time of medical workers depending on the occupied position») the week norm of work time of a dentist equals 33 hours or 6 hours 36 minutes a day (396 minutes), dental assistant – 38,5 hours or 7 hours, 42 minutes a day (462 minutes).

While projecting norms for a dentist we consider the so-called coefficient of work time usage for the direct treatment-diagnostic activity that equals 0,923 (the order of Federal fund of obligatory medical insurance of RF № 72 of 12.10.1995 «On methodic recommendations while calculating tariffs for ambulatory-polyclinic treatment»).

Everyday load of a dentist who works with four hands equals:

Eqn2.wmf.

While working with four hands an average planned number of visits for dental therapeutist and dental assistant can equal 7.

Resume. The article presents some results of normalization of labour and calculation of work load in terms of work with dental assistant with four hands.
