Enamel caries in the stage of white (chalk) spot is a common dental pathology, for the treatment of which modern minimally invasive methods, namely microabrasion and infiltration are used.

The study objective is to evaluate and compare in the dynamics indices of dental status in the treatment of enamel caries in the stage of white (chalk) spot by microabrasion and infiltration methods.

MATERIAL AND METHODS

During the clinical study 80 patients with diagnosis of «K02.0 Caries limited to enamel. White spot lesions (initial caries)» were treated by microabrasion and infiltration methods. Dental status was assessed by following indices: tooth decay rate according to the CFE index; PHP index (A.G. Poshadley, P. Haley, 1968) of oral hygiene effectiveness; gingiva sulcus bleeding according to the modified SBI index (Muhlemann, 1971); CPI communal periodontal index (WHO, 1997); IDHI index of dental hyperesthesia intensity. The changes in the indices were analyzed at four time points: at primary examination; after oral hygiene; 1 month after procedure; 12 months after treatment.

RESULTS

An index assessment showed that after microabrasion and infiltration, dental condition was improved both immediately after treatment and after 1 year. In the same time, the microabrasion method was characterized by higher values of caries recurrence prevention (97% against 86% when using the infiltration method), and the method of infiltration — by absence of negative impact on increasing the sensitivity of the teeth.

CONCLUSION

The choice of treatment method of enamel caries in the stage of white (chalk) spot should be based on an index assessment of the hygienic condition of the oral cavity, condition of periodontal tissues, level of enamel resistance and sensitivity of the teeth.
