strongBACKGROUND/strongPericoronitis is inflammation of the tissue surrounding a third molar, or wisdom tooth. This study aimed to evaluate the effects of oral and topical analgesic nonsteroidal anti-inflammatory drugs (NSAIDs) on oral health-related quality of life (OHQoL), in terms of oral health and lifestyle, in patients with symptomatic pericoronitis.strongMATERIAL AND METHODS/strongThe study included 60 patients who presented with pericoronitis and who did not undergo surgery within the following seven days. The patients were randomly assigned to three groups and were treated with oral diclofenac (N=20), oral flurbiprofen (N=20), and topical benzydamine (N=20). OHQoL was assessed for all study participants with a self-reported eight-item scale that was developed to evaluate pericoronitis. The total OHQoL scores were calculated for each day during the seven-day study period.strongRESULTS/strongThe study group treated with topical benzydamine had a significantly greater improvement in the OHQoL scores compared with the oral diclofenac and oral flurbiprofen groups on the first four days. Comparison of patients treated with diclofenac and flurbiprofen showed no significant differences for all seven days. A significant initial improvement in OHQoL was found on day 1 for the benzydamine group, on day 2 for the flurbiprofen group, and day 3 for the diclofenac group.strongCONCLUSIONS/strongIn this study, topical benzydamine was found to be a more effective alternative to oral NSAID analgesics, diclofenac and flurbiprofen, in improving OHQoL in patients with pericoronitis.

Objective: This study aims to experimentally investigate the efficiency of Ankaferd Blood Stopper (ABS) on early and long-term bone healing and its effects on bone surfaces. Materials and Methods: Thirty adult male Wistar albino rats were used in the study. These rats were randomly divided into three groups, and bilaterally bone defects were created in the femur of each rat. A 3.0-mm-deep monocortical circular defect was created with a 3.0 mm diameter trephine drill on the proximal part of the femur, and 0.05 mL ABS was applied to the experimental group while the control group was left untreated. Group 1, group 2, and group 3 rats were sacrificed on days 7, 28, and 42, respectively. Trabecular bone area (Tb.Ar), medullary bone diameter (Me.Dm), osteoblast area (Ob.Ar), osteoid area (O.Ar) and mineralized bone area (Md.Ar) were examined in the histomorphometric analysis. Also new bone formation was scored according to the histologic evaluation Results: The results showed that while new the to day 7 experimental group showed much more bone formation than the to day 7 control group, there was no significant difference between the to day 28 and day 42 experimental groups and to day 28 and day 42 control groups. Accordingly, ABS applied in bone cavities only had a larger accelerator effect on bone healing for the seventh-day to day 7 experimental group. In clinical observations, no allergic or inflammatory reactions were observed on the skin and other preoperative and postoperative periods. Moreover in, the histomorphometric study, necrotic areas and infection areas were not observed. Conclusion: ABS has an acceleratory effect on the short-term bone healing process and is a reliable agent for routine use. However, its effects on the long-term bone healing process are insignificant. We think that a wide series of research projects are required to confirm the effects of ABS speeding up the healing process in addition to its characteristic as a blood stopping agent. Conflict of interest:None declared.

OBJECTIVE The objective of this study was to determine whether smoking causes pathological changes, comparing intensity of epidermal growth factor receptor (EGFR) expression in smokers' and nonsmokers' pericoronal follicles located around asymptomatic impacted lower third molars. STUDY DESIGN Eighty-two dental follicles were collected from asymptomatic mandibular third molars of 41 smoker and 41 nonsmoker patients. Specimens were examined immunohistochemically using antibody against EGFR. RESULTS The expression of EGFR in smokers' pericoronal follicles was higher as compared with nonsmokers (P = 0.036). Also, high EGFR expression was detected in female smokers than in female nonsmokers (P = 0.01). There was a statistically significant correlation between pack-years and EGFR expression intensity in male patients. CONCLUSIONS The risk of pathological differentiation in pericoronal tissues of smoking patients is higher than in the nonsmoking patients. This factor may be taken into account when deciding whether to remove an asymptomatic impacted lower third molar.

A case of multiple bilateral dens invaginatus in the maxillary incisor teeth and an impacted cuspid has been presented. The impacted cuspid was removed surgically.
