    This study evaluated the effect of alloplastic bone grafts in osseous defects following surgical removal of horizontally impacted third molars by comparing the periodontal measures distal to the second molar in grafted and nongrafted third molar extraction sites. Materials and Methods: A double-blind, randomized, controlled clinical trial was designed on subjects with bilateral horizontally impacted mandibular third molars. Grafting consisting of alloplasts at the third molar extraction sites was compared with nongrafted sites. This study assessed 54 randomized sites in 27 patients who were selected using a split-mouth design. The predictor variable included the change in pocket depth distal to the mandibular second molar and associated dentin hypersensitivity around the second molar, assessed preoperatively and at 3 and 6 months after third molar surgery. The data regarding pocket depth reduction was statistically analyzed using paired t-test. The data concerning reduction in dentin hypersensitivity was statistically analyzed using chi-square test. Results: Six months after third molar surgery, mean pocket depth distal to mandibular second molar decreased significantly at the grafted sites compared to the nongrafted sites. The reduction in dentin hypersensitivity of mandibular second molar was statistically significant for the grafted sites at 6 months, compared to the nongrafted sites.

    Background: Third molar impaction, if left untreated, has the potential to cause several complications. The evaluation of surgical difficulty of impacted third molar extraction aids in better formulation of treatment plan by minimizing surgical complications.

    Objective: This study aimed to determine the prevalence of third molar impaction and related pathologic conditions in a cohort of patients living in North-eastern Peninsular Malaysia.

    Methods: In this retrospective study, 490 orthopantomograms (OPGs) of patients who were referred to the Oral and Maxillofacial Surgery department between January 2010 and December 2019 were assessed. Data including age, gender, ethnicity, frequency of third molar impactions, their angulations and levels of eruption, retromolar space, and associated pathologic conditions were collected. Statistical analysis was performed using the Statistical Package for Social Sciences (SPSS) version 24.0. The significance level was set to P < 0.05.

    Results: A total of 490 patients with a mean age of 28.87 years (range: 20-64) demonstrated 1957 impacted third molars (1022 mandibular + 935 maxillary). Impacted third molars were more likely present in females than males (1:2.20) (p < 0.05); and in Malay-ethnic (44.49%) patients followed by Chinese (34.45%) and Indians (21.02%). Mesioangular was the most common angulation of impaction both in the maxilla (24.68%) and mandible (18.34%). The most common pattern of third molar impaction was IIA (61.67%), and the retromolar space was significantly larger in males (13.6 mm; P < 0.05) than females (11.6 mm). The most frequently occurring pathological condition associated with third molars impaction is dental caries in the second or third molar (15.38%).

    Conclusions: This study highlights mesioangular impaction with their occlusal plane at the same level as the occlusal plane of the adjacent tooth being the most prevalent pattern of third molar impaction in North-eastern Peninsular Malaysia.

    INTRODUCTION: The use of corticosteroids to reduce the post-operative sequelae of lower third molar surgery, namely pain, swelling and trismus, has been well studied by many researchers over the past 6 decades. This study reviewed the reported outcome of corticosteroids used in controlling the above sequalae after third molar surgery.

    MATERIALS AND METHODS: A PubMed, Medline, EMBASE and Google search was undertaken of all controlled clinical trials on the effects of corticosteroids on pain, swelling and trismus after lower third molar surgery. The review was limited to studies published over the last 10 years (2006-2015).

    RESULTS: Of the 46 initially retrieved articles, 34 were finally included. Eleven studies compared the effect of 2 similar (but different dose) or different group of corticosteroids. Thirty-one studies reported the effects of corticosteroids on all sequale, 2 reported the outcome on swelling and trismus and another 1 on swelling and pain only. In 16 of the studies, corticosteroid use resulted in significant reductions in pain after third molar removal. Twenty-two out of 29 studies reported reduced swelling against negative control while 18 out of 25 studies reported improved mouth opening. Fourteen studies reported the benefit of corticosteroids on all 3 sequelae, with 71.4% resulted from the use of methylprednisolone.

    CONCLUSION: Although there are some conflicting effects, the results of this analysis shows in general the benefits derived from short-term use of corticosteroids in relation to pain, swelling and trismus following third molar surgical extraction, with no side effects observed.

    The objectives of this systematic review were to investigate the efficacy of amoxicillin/amoxicillin-clavulanic acid for reducing the risk of postoperative infection after third molar surgery and to evaluate the adverse outcomes in these patients, as well as in healthy volunteers. A systematic search of four databases was performed on May 26, 2017. Eleven studies qualified for the qualitative analysis and eight were found suitable for meta-analysis. The results suggest that both amoxicillin-clavulanic acid and amoxicillin significantly reduce the risk of infection after third molar extraction (overall relative risk (RR) 0.25, P<0.001). However, with the exclusion of randomized controlled trials with a split-mouth design (due to an inadequate crossover period after antibiotic treatment), only amoxicillin-clavulanic acid was found to be effective (RR 0.21, P<0.001). The risk of adverse effects was significantly higher in the amoxicillin-clavulanic acid group (RR=4.12, P=0.023) than in the amoxicillin group (RR 1.57, P=0.405). In conclusion, amoxicillin-clavulanic acid and amoxicillin may significantly reduce the risk of infection after third molar extraction. However, their use in third molar surgery should be viewed with caution, as recent clinical trials on healthy volunteers have shown evidence of the negative impact of amoxicillin use on bacterial diversity and antibiotic resistance.

    The results of the present investigation have shown the usefulness of suprofen in the control of pain following surgical removal of impacted wisdom tooth. The regime of 200 mg. q.d.s. orally, was shown to be satisfactory in the control of postoperative pain. Pain was rapidly controlled by the 1st hour after ingestion and subsequently maintained at a low profile until is was completely abolished by the 8th hour of the postoperative period.

    PURPOSE: To compare the efficacy of preoperative submucosal injection of 4 mg of dexamethasone versus 40 mg of methylprednisolone in reducing postoperative sequelae after surgical removal of impacted mandibular third molars.

    PATIENTS AND METHODS: This prospective, randomized, double-blind study included 65 patients who required surgical removal of impacted mandibular third molars with Class II or position B impaction (Pell and Gregory classification). Patients were randomly assigned to 1 of 3 groups: dexamethasone, methylprednisolone, or placebo (control). Surgery was performed with patients under local anesthesia. Baseline measurements were obtained preoperatively, and subsequent assessments were made on postoperative day 1, 2, 5, and 7 to measure postoperative facial swelling by use of 2 linear measurements: interincisal mouth opening width and visual analog scale score for pain. The amount of analgesics consumed was recorded. Wound healing also was assessed on postoperative day 7. Descriptive and multivariate statistics were computed, and significance was set at P

    This study compares the use of inhalation sedation using sevoflurane (group S) with inhalation sedation using nitrous oxide (group N) in patients undergoing bilateral extraction of third molar teeth under local anaesthesia. The study was designed as a cross-over study. Seventeen ASA I, day surgery patients were studied. Patients were randomly allocated to receive either 8 l/min 50% nitrous oxide in oxygen (group N) or same flow of 1% sevoflurane (group S) for the first procedure. Each patient then had the alternate method of sedation for the second procedure. There were no significant differences between the methods in patient co-operation and surgeon's satisfaction with sedation. Psychomotor tests were comparable in both groups. The patients were significantly more sedated in the group S compared to group N (P=0.004). Significantly more patients complained of an unpleasant odour group S (P<0.01) but none withdrew from the study for this reason. No adverse cardiorespiratory effects resulted from sevoflurane or nitrous oxide sedation. Both methods gave good amnesia during the procedure. There was high acceptance of both methods and the patients rated the technique as equally satisfactory. We conclude that inhalation sedation with sevoflurane is a suitable alternative method to nitrous oxide sedation.

    The retromolar foramen (RMF) and retromolar canal (RMC) are the anatomical structures of the mandible located in retromolar fossa behind the third molar tooth. This foramen and canal contain neurovascular structures which provide accessory/additional innervation to the mandibular molars and the buccal area. These neurovascular contents of the canal gain more importance in medical and dental practice, because these elements are vulnerable to damage during placement of osteointegrated implants, endodontic treatment and sagittal split osteotomy surgeries and a detailed knowledge of this anatomical variation would be vital in understanding failed inferior alveolar nerve blockage, spread of infection and also metastasis. Although few studies have been conducted in the past showing the incidence and types in different population groups, a lacunae in comprehensive review of this structure is lacking. Though this variation posed challenging situations for the practicing surgeons, it has been quite neglected and the incidence of it is not well presented in all the textbooks. Hence, we made an attempt to provide a consolidated review regarding variations and clinical applications of the RMF and RMC.
