Background and aims. Wound dehiscence after lower third molar surgery extends the postoperative treatment period and may cause long-standing pain. The aim of this study was to compare wound dehiscence after removal of wisdom teeth in the most prevalent mandibular impaction (mesioangular class IB) by two different soft tissue flap designs.Materials and methods. Partially-erupted mandibular third molars with mesioangular class IB impaction (Pell and Gregory classification) were selected. Split mouth technique was used to compare the two flap designs (envelope vs. triangular transposition flap—TTF). The patients were recalled one week and a month later and rechecked for dehiscence, infection, and dry socket formation.Results. There were no cases of infection in either group. However, three cases of dry socket in the envelope group and four in the TTF group were recorded. In the envelope group, dehiscence occurred in 43% of cases during the first week, with 67% of cases being a large dehiscence (diameters of more than 5 mm). Extra appointments (those requested by the patient exclusively related to the problem of the hole distal to the second molar) were scheduled in 10% of cases in the envelope group. In the TTF group, dehiscence occurred during the first week for the same impaction in 19% of cases with large dehiscence cases occurring in 65% of cases and extra appointment rate at 4.1%.Conclusion. According to theresults in the evaluated operation, TTF may prevent postoperative wound dehiscence more probably than the envelope flap.

Background and aims. Periodontal disease is common among adults and is a potential source of chronic inflammation. Recent data have suggested an important role for chronic inflammation in the development of coronary heart disease (CHD). The purpose of this study was to address cardiologists’ knowledge regarding the effects of periodontal diseases on coronary heart system. Materials and methods. A cross-sectional study was designed for cardiologists in Tabriz, Iran. A total of 54 cardiologists participated in the study. Each participant was given a self-administered questionnaire. It was a closed-ended questionnaire with responses presented as yes/no/don’t know choices. Data were analyzed using descriptive statistics. Results. Cardiologists’ knowledge about periodontal disease was moderate. Eighty-two percent of cardiologists agreed that inflammation is a key component between periodontal disease and CHD; 76% agreed that controlling infection and inflammation is important for managing CHD and 62% reported not receiving any education on oral healthcare. Eighty percent of cardiologists believed that medical and dental students should be trained to work collaboratively. Conclusion. It is important for educators and administrators in higher education to examine the need for interprofessional education and collaboration between medicine and dentistry.
