The state of the tooth pulp, prepared for veneers
Abstract
The pulp reaction was studied for preparation and fixation of veneers with the help of the electronic pulp test device IVN-01 Pulptest Pro. Veneers were installed in 109 patients, the average age was 31,40 ± 3,51 years. In 36.7% of cases, a change in natural color, pigmented enamel fissures was noted, in 28.4% of cases - a change in shape and size, tooth erosion, in 22,0% of cases - a change in the position in the dentition, dullness of the teeth, at 12,8 % of cases - a combination of the listed characteristics. In 65,1% of patients, ceramic veneers were installed, and 34,9% had composite veneers. A total of 288 veneers were fixed. Initially, the highest excitability was noted in molars, the lowest at the incisors. Immediately after the restoration, the electrical excitability of teeth with installed ceramic veneers increased by 16.9%, with composite veneers - by 29,9% (p < 0,05), after 12 months. Electroexcitability decreased both in patients with ceramic and composite veneers, but exceeded the initial index by 11,8% and 19,8%, respectively. The sensitivity of the teeth prepared for veneers, regardless of the type of veneer, was statistically significantly different from healthy teeth, which indicated a lack of secondary inflammatory-degenerative changes in the pulp, and that the preparation did not cause pathological changes.
