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 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.
