RESUMEN
This report investigated the effectiveness of non-pharmacological interventions for reducing dental fear and anxiety in patients undergoing third molar extraction under local anesthesia. In November 2020, multiple electronic databases (Cochrane, EMBASE, MEDLINE, PsycInfo, PsycArticles, PubMed, and Web of Science) were searched for articles published in English. Inclusion criteria were randomized-controlled trials reporting the effectiveness of any non-pharmacological interventions in reducing fear or anxiety levels in patients with third molar extraction. A total of 3015 studies by electronic search and 2 studies by hand search were identified. After screening, 21 studies were eligible for systematic review. Seven studies were included in the meta-analysis. Study selection, data extraction, and quality assessment of the included studies were performed by two independent investigators. The anxiety levels after intervention in each study were pooled and meta-analyzed by the random-effect model. A significant reduction in anxiety level was observed in non-pharmacological intervention groups (SMD = -0.32; 95% CI -0.57 to -0.07; p = 0.01). Subgroup analyses showed that a significant anxiety reduction by non-pharmacological interventions could be demonstrated by pooled data from studies using psychometric assessments, but not from studies using physiological assessments. Non-pharmacological interventions appear to reduce fear and anxiety levels in patients undergoing third molar extraction under local anesthesia.

PURPOSE: This double-blind randomized crossover study compared the analgesic efficacy of pre- and postoperative administration of oral pregabalin 75 mg using a postsurgical dental pain model. MATERIALS AND METHODS: Patients requiring third molar surgery in 2 separate stages under local anesthesia were recruited. They were given pregabalin 75 mg either 1 hour before or after their first surgical extraction. They then received the same dose of pregabalin at their second surgical extraction, but those who received it before surgery received it postsurgery, and vice versa. Postoperative analgesic effects were assessed at postoperative hours 2, 4, 8, 12, 24, 48, and 72. Time to first analgesic, analgesic consumption and adverse events were also evaluated. RESULTS: Forty patients were recruited, and 34 completed the study. The area under curves for numerical rating scale pain scores 1 to 24 hours were significantly lower at rest but not during mouth opening for patients receiving postoperative pregabalin (P < .048). Pain relief was similar for the period of 24 to 72 hours. No significant difference was found in time to first analgesic, total analgesic consumption, and side effects between preoperative and postoperative groups. No difference in the incidence of adverse events was noticed in relation to the timing of pregabalin administration. CONCLUSIONS: Postoperative administration of oral pregabalin 75 mg appears to offer better analgesic efficacy than preoperative administration after third molar surgery under local anesthesia.

PURPOSE: To conduct a systematic review to answer the clinical question, "What are the available treatment modalities and their outcomes of neurosensory deficit after lower third molar surgery?" MATERIALS AND METHODS: A systematic search, including a computer search of several databases with specific keywords, a reference search, and a manual search of 3 key maxillofacial journals were performed. Relevant articles were then evaluated and those that fulfilled the 6 predetermined criteria were chosen to enter the final review. The various treatment modalities and their outcomes of neurosensory deficit after lower third molar surgery, in the selected studies in the final review, were analyzed. RESULTS: Ten articles entered the final review. Six treatment modalities of lingual nerve or inferior alveolar nerve deficit after lower third molar surgery were identified. External neurolysis, direct suturing, autogenous vein graft, and a Gore-Tex tube as a conduit were the 4 surgical treatments. Significant improvement after surgical treatment ranged from 25% to 66.7%. Acupuncture and low-level laser therapy were 2 available nonsurgical treatment modalities that were found to have produced significant improvement in sensation after treatment in more than 50% of subjects. There was insufficient information to determine the best timing of treatment of nerve injury after third molar surgery. CONCLUSIONS: Four surgical treatments and 2 nonsurgical treatments were identified in the management of neurosensory disturbance after lower third molar surgery. Most treatments showed an improvement in sensation but the outcomes were variable. Complete recovery was uncommon in all kinds of available treatments.
