Abstract:

We analyzed parameters characterizing mineral balance in a body and dental state in two groups of healthy men (n = 15 in each, aged 34.7 ± 0.6) in hot and humid marine climate conditions; one group was made of people undergoing acclimatization, the second one consisted of local population.

We assessed working conditions and their category, and metrological data with determining environmental thermal load (ETL-index).

Both groups worked outdoors; their labor had IIb category; they had to work overtime and under increased psy-choemotional loads; their working conditions differed as per nutrition and accommodation. When people from both groups had to work beyond their permanent location, their nutrition was represented by individual rations.
Labor hardness was assessed as 3.2; labor intensity, as 3.2. Daytime temperature reached 30,0 С, relative air humidity was 77.3 ± 2.6 %, wind speed was 4.3 ± 0.3 m/sec. Microclimate was assessed as having 3.1 hazard category. Overall, working conditions were assessed as hazardous (3.3 hazard category).

Electrolyte balance in a body was violated and it was proved by ower contents of K, Na, and Cl in blood serum; it was more apparent in people who were undergoing acclimatization. 70.0 % of local people had Ca contents in blood serum lower than the physiological standard. Lower Ca and increased P contents in blood serum were also detected in those undergoing acclimatization which could be evidence that Ca was washed out of a body and greater risk of dental caries occurred. As per observation dynamics we detected the following processes in people undergoing acclimatization: pH saliva and its mineralizing function shifting to acidity, salivation rate, and lower enamel resistance; they proved there was a growth in dental solid tissues demineralization. These parameters corresponded to those detected in local population. It calls for primary prevention activities aimed at fighting caries of dental solid tissues.
