Introduction: Bone regeneration materials are often used in dental surgery procedures. At present, we have the possibility to use materials from different groups due to the way they are obtained. The gold standard still remains the use of autogenous bone substitute material due to its osteogenic, osteoinductive and osteoconductive properties. The surgical removal of the third retained tooth is one of the most common procedures performed in dental surgery. As a result of such a procedure, bone tissue atrophy occurs. In order to avoid the formation of a bone defect on the distal surface of the second molar, an augmentation method using an autogenous dentin matrix can be used in such procedures. Material and methods: Procedures for bilateral removal of retained third molars were performed in 15 patients. On one side, augmentation was performed with an autogenous dentin matrix obtained by grinding and preparing the extracted retained tooth (study group). On the opposite side, the bone defect was left to heal spontaneously (control group). After 6 months, the degree of bone regeneration was compared on the basis of bone density testing and the size of the resulting bone defect on the distal side was compared on the basis of radiographic examination. Results: Analysis of the obtained material showed significant differences in healing after treatments with autogenous dentin matrix. Thus, the use of an autogenous dentin matrix made it possible to obtain a completely regenerated bone defect. Conclusions: This procedure seems to be useful for bone regeneration after the removal of the third molar.

Introduction. There are reports in literature which indicate the connection between impacted third molars and occurrence of symptoms of craniomandibular dysfunctions and headaches. Objectives. The aim of this study was evaluation of the outcome of patients who reported specific symptoms of craniomandibular dysfunction and had impacted mandibular third molars. Materials and method. The research material consisted of 10 women who reported to the Department of Craniomandibular Disfunctions of the Medical University in Lublin, Poland, with pain and acoustic symptoms in the Temporomandibular joint (TMJ) area. During preliminary therapy, the patients used a silicone occlusal device; ionotherapy was ordered and the patients were recommended to eliminate parafunctions. Results. Clicks before treatments were present in 6 patients, after treatment with silicone occlusal device and ionotherapy with Profenid gel in 5 patients, while two years after extraction of the impacted teeth the clicks were no longer present, and differences in the presence of clicks analyses by means of the Q-Cochran test were statistically significant between examinations 1m vs.3 (Q=10.33; p<0.01) and examinations 2 vs.3 (Q=8.40; p<0.05). Conclusions. The study showed that extraction of the mandibular third molars can cause regression of some symptoms of craniomandibular disorders.
