This study revealed that the distribution and characteristics of benign tumors and tumor-like lesions of oral cavity and jaws in the Turkish population, particularly including the Eastern region of Turkey have some differences as well as similarities with the findings of studies in different populations.

BackgroundCollagen membranes have some benefits include promoting wound healing through isolation, clot stabilization, wound stability, and hemostasis, enhancing primary wound coverage through its chemotactic ability to attract fibroblasts, and augmenting flap thickness by providing a collagenous scaffold. The purpose of this study was to compare primary and secondary healing and collagen membrane-based primary healing after surgical removal of partial impacted mandibular third molars, evaluating the incidence of postoperative complications and analyzing the swelling, mouth opening, and pain.MethodsThis was a prospective, randomized controlled study. Patients were randomly assigned to three groups: the SC (Secondary closure) group, the PC (Primary closure) group, and the MBPC (membrane based primary closure) group. Data were collected on pain, mouth opening, swelling, and complications experienced by the patients.ResultsThere was no statistically significant difference between the groups for the pain (p > 0.05), relatively. The swelling recorded on postoperative days 2 and 7 was lower in the SC group than in the PC (p = 0.046 and 0.00) and in MBPC (p = 0.005 and 0.002) groups, respectively. Mouth opening showed a statistically significant difference between the three groups at day 2 (p = 0.00). Wound dehiscence was shown in 6 patients in the PC (20%) group and 2 patients in the MBPC (6.7%) group. Dry socket was observed 3 patients in the SC group (10%), 2 patients in the PC group (6.7%), and no dry socket in the MBPC group. No cases of infection or postoperative bleeding were encountered.ConclusionsThe secondary closure provides a marked advantage over the primary closure in terms of swelling and mouth opening. However, the absence of alveolitis in the primary closure using the collagen membrane and minimal wound dehiscence, suggests that membrane use may support primary healing in terms of wound healing.

The purpose of this study was to evaluate the sufficiency of the mandibular symphysis as a donor site for unilateral and bilateral alveolar grafting, measuring both the alveolar cleft volume and maximum bone graft volume that can be harvested from the mandibular symphysis using 3-dimensional computed tomography (CT) and software in children and adults. Computed tomography data obtained from 20 unilateral and bilateral cleft lip palates patients in the preoperative period were used in this study. The patients were divided into 2 groups: children (female, n = 5; male, n = 5) and adults (female, n = 5; male, n = 5). The required bone graft volume for grafting and the maximum bone graft volume that can be harvested from the mandibular symphysis were measured based on cone beam CT data and software. The average required bone graft volume (cleft volume) for unilateral alveolar grafting was 963.51 ± 172.31 mm in the children and 1001.21 ± 268.16 mm in the adults. The average required bone graft volume for bilateral alveolar grafting was 1457.82 ± 148.18 mm in the children and 2189.59 ± 600.97 mm in the adults. The average the mandibular symphysis bone graft volume was 819.29 ± 330.85 mm in the children and 2164.9 ± 1095.86 mm in the adults. The results demonstrated that the mandibular symphysis region provided an adequate bone volume for alveolar grafting in adults with unilateral alveolar clefts. However, it is difficult to standardize these results, due to cleft volume and graft volume that could be harvested from the mandibular symphysis are highly variable among individuals.
