Bispectral photodynamic therapy after the extraction of third molars

Abstract

Findings obtained after the present trial have confirmed that in patients with extracted third molars reparative processes in wounds are more rapid if wound holes are treated with low-level bispectral laser light.Purpose: to confirm improved reparation, less pain syndrome, and less inflammatory reactions in wounds after the extraction of third molars if laser photodynamic therapy was used in the postoperative period.Material and methods. Given the extraction of eight teeth is a rather traumatic procedure, the authors proposed a technique for treating inflammatory processes in the mucous of maxillofacial area. To implement this technique in the postoperative period, they treated wound surface with photodynamic technique including a photoactive sensitizer. If upper and lower wisdom teeth were removed simultaneously, phototherapy with low-level laser light and bispectral nozzle was applied unilaterally on days 2, 3 and 5, while the other side was not treated at the rehabilitation period. To confirm the effectiveness of the proposed curative technique, scrapes from the wound surface of teeth holes were taken and examined cytologically on days 3, 7 and 12. Staining by Pappenheim and azur-eosin was applied. A randomized simple blind experiment was conducted; a double-blind experiment was a part of morphological examination.Results. Smears from the wound surface were examined on days 3, 7 and 12 to find qualitative and quantitative composition of cytological preparations. A statistically significant difference (p < 0.05) was found indicating that the performed physiotherapeutic care significantly improves reparative processes.
