Introduction: Bone defects in the jaw are frequently observed after odontogenic cyst enucleation. The success of bone healing appears to be related to the size of the bone defect, the anatomical location, the patient’s age and other parameters. The use of bone grafting material is dependent on the operator’s preference. No evidence-based definite treatment protocol has been established. This study evaluated the effect of a bone graft into the defect after odontogenic cyst enucleation. Materials and Methods: A total of 55 patients, who had been treated for an odontogenic cyst with cyst enucleation from 2000 to 2009 at the department of Oral and Maxillofacial Surgery, Samsung Medical Center, were included in this study. Patients who were followed-up for more than 1 year were included. Two groups were defined according to the bone graft (with or without a bone graft) after cyst enucleation. The differences in the healing periods and patterns of bone healing were compared clinically and radiologically. The postoperative 1 year radiographs were analyzed for bone healing and density. Statistical analysis was performed using a Pearson chi square test and Wilcoxon rank-sum test. Results: More infection signs were observed in the bone graft group than in the other group, but there was no statistically significant difference. Radiographically, there was also no significant difference in the size of the radiolucent lesions between the two groups. Conclusion: There was no significant difference in healing between the groups with a bone graft and without bone graft after cyst enucleation.

Introduction: This study examined the genetic influence of mandibular prognathism epidemiologically in Korean families. Materials and Methods: Over a 5-year period from 2005 to 2009, a questionnaire with a pedigree chart was given to 100 (male 51, female 49) probands with skeletal Class III mandibular prognathism, who had undergone orthognathic surgery in Samsung Medical Center. Results: The average age of the probands was 22.1. The average SNA, SNB and ANB angles of the probands were 81.2, 84.1and -2.9, respectively. A total of 2729 (male 1,354, female 1,375) family members were examined, and the affected ratio of the families was 3.5% with no significant difference between genders. 45% of families had at least one member with a Class III malocclusion other than the proband. The affected ratio of the first-degree relatives (10.9%) was significantly higher than those of the second-degree (3.3%) and third-degree (1.9%) relatives. The affected ratio of the total relatives from the male probands (4.2%) was significantly higher than that of the female probands (2.8%). Heritability (h2, Falconer’method) was estimated to be 29.8% (0.298±0.059) in first-degree relatives. Conclusion: These results showed the significant influence of mandibular prognathism with relatively low heritability in first-degree relatives in Korean families of probands, who had undergone orthognathic surgery to correct a skeletal Class III malocclusion.
