[Incidence of dental caries and dental calculus in the front dentition]

The attempt had been made to determine interrelations in the incidence of dental caries and dental of frontal dentition in a total of 100 healthy individuals aged 21-40 years. Caries susceptibility was evaluated as averagely higher in the upper frontal denture and lower in lower one. Both supragingival and subgingival forms of dental calculus were of rare occurrence in upper portion, and they occurred massively in lower portion of denture. In the upper frontal portion, the significant correlation has been stated statistically between the caries susceptibility and the quantity of both forms of dental calculus. The higher was caries susceptibility, the lower was the amount of dental calculus. The lower frontal denture showed the significant differences as to the incidence of supragingival calculus at various degree of caries susceptibility in the same sense as in the upper one. No difference in unsatisfactory status of dental hygiene was determined in both portions observed. The periodontal disorder was more expressed with age and it showed no significant difference in both mentioned portions.
