Abstract
Dry socket is one of the most common complications of teeth extractions. Etiology and pathogenesis of dry socket are not clearly known but many related predisposing factors have been discussed. According to this, a cross- sectional study was conduced at the department of oral and maxillofacial surgery (Tehran University of Medical Sciences, Oct. 97- Jul. 98). 4880 teeth were extracted which 25 of them recalled with dry socket. The relationship between the effective factors and dry sockets was evaluated. The effective factors were as follows: age, sex, site of extraction, and trauma during exctraction, infection, oral hygiene, smoking, and systemic diseases. Results showed that the incidence of dry socket was %0.5, and the number of cases observed in women was two times more than men. Also, mandibular third molars were involved more than any other areas.

Abstract

  Background and Aims: The increase in the number of complex implant cases has drawn the attention of researchers toward materials having bone regeneration promoting ability. Socket preservation and bone graft are recommended to minimize bone resorption. The aim of this study was to evaluate a kind of xenograft collagenic bone (osteo biol gen_oss) in socket regeneration.

  Materials and Methods: This randomized clinical trial was performed in 12 cases (6 in test and 6 in control groups) with two hopeless teeth. After tooth extraction, in test group, graft material was put in sockets but in the control group the socket was healed naturally. Three months later, during implant placement the specimens from both sites were sent to a pathologist for histologic and histomorphometric evaluations. Data were analyzed using Mc Nemar and Wilcoxan sigh rank test (α=0.05).

  Results: There were no significant differences between two groups in foreign body reaction, inflammation, bone vitality and percentage of bone gain. Average percentage of residual graft in test site was 6.73±1.43.

  Conclusion: Osteobiol gen_oss xenograft is an appropriate biocompatible osteoconductive material that promotes bone regeneration at 3 months following socket preservation in human extraction sockets.

Abstract
Background and Aims: Dry socket is one of the most common post-tooth-extraction complications. The aim of this study was to investigate the relationship between some of the predisposing factors of dry socket and this complication in all maxillary and mandibular molars and evaluation of its incidence. Furthermore, the two jaws were compared.
Materials and Methods: In this descriptive-analytical cross-sectional study, 150 patients were examined in 2020 in the city of Zahedan. A questionnaire consisting of two sections was designed: In the first section age, gender, systemic disease, smoking status, contraceptive pill consumption, and antibiotic consumption were investigated. In the second section, data related to the difficulty of surgery based on the duration of surgery and the number of local anesthetic cartridges that were administered were collected. Then, the collected data were analyzed by Chi-square and Kruskal-Wallis tests.
Results: The incidence of dry socket was 25.3%. The frequency of dry socket was significantly relevant to smoking, oral contraceptive consumption, difficulty of the surgery, and the number of local anesthetic cartridges that were administered (P≤0.05). Age, gender, controlled systemic disorder, and systemic antibiotic usage for two weeks prior to surgery revealed no significant associations with dry socket (P>0.05). Furthermore, the frequency of dry socket in maxillary and mandibular jaws had a significant difference according to smoking status, difficulty of surgery, and number of local anesthetics carpules (P≤0.05).
Conclusion: It is recommended to identify high-risk groups when performing extraction to consider pre-operative and post-operative measures in order to reduce postoperative complications.
