THE AIM OF THE STUDY

To study the effectiveness of percutaneous electroneurostimulation (TENS) for normalization of masticatory muscle tone and improvement of the effectiveness of permanent dental prosthetics in patients with increased tooth wear.

MATERIALS AND METHODS

Electromyographic examination (EMG) was performed in 20 patients of both sexes aged 35 to 54 years, in patients with a clinically pronounced generalized form of increased tooth wear and temporomandibular joint (TMJ) dysfunction. Patients complained of soreness and tension in the area of the masticatory muscles during mouth opening and chewing. The examination was performed using an electromyograph “Synapsis” (Neurotech), adapted for dental purposes. All patients were prescribed a TENS course of up to 5 sessions, lasting 45 minutes, and additionally a muscle relaxation mouthguard was manufactured.

RESULTS

The results of the electromyographic examination at the first stage (up to TENS) showed a pronounced asymmetry of the masticatory muscles: the predominant muscles are the left temporal (Ts) — 449+27 (MV) and the left masticatory proper (Ms) — 387+27 MV, the lowest values were noted in the right temporal muscle (Td) — 326+15 Mv and the right masticatory muscle (Md) — 352+21 mcV. The difference between the average amplitude of Md and Ms muscles was 35 Mv, and the difference between Td and Ts muscles was 123 Mv, statistically significant. At the second stage, a TENS course of up to 5 sessions was prescribed. The highest values were observed in the left temporal muscle (Ts) — 437+27 Mv, the lowest in the right (Td) — 346+28 Mv. The indices of the right masticatory muscle proper (Md) were 398+37 Mv, the left (Ms) — 377+32 mv. The difference between the average amplitude of Md and Ms muscles was 9 Mv, and between Td and Ts muscles — 21 Mv.

CONCLUSION

After a course of TENS in patients with increased tooth wear, positive dynamics of changes in the bioelectric conductivity of the chewing muscles are determined. Electrical impulses contributed to the improvement of the functional characteristics of the stimulated muscles, which proves the importance of using percutaneous electrical stimulation to increase the effectiveness of treatment in this group of patients.
