A Comparison between Inferior Alveolar Nerve Block and Crestal Anesthesia in Children Undergoing Dental Extraction Procedure

Objective: To evaluate the efficacy of crestal anesthesia compared to the inferior alveolar nerve block (IANB) in 6–9-year-old children undergoing tooth extraction. Material and Methods: This case-control study was conducted on 70 children who needed bilateral mandibular primary molar extractions. The Faces Pain Scale was used to determine the efficacy of the anesthetic technique. Demographic data, onset time of anesthesia, duration of anesthesia, and blood pressure were also recorded. The data were analyzed using SPSS 25 and analytical tests: t-test, chi-squared test, and one-way ANOVA. The level of significance was set at p<0.05. Results: The efficacy of the IANB was significantly higher than the crestal anesthesia (p<0.05). The duration of IANB anesthesia was significantly more than the crestal anesthesia (p<0.05). The two anesthetic techniques showed no significant differences in pediatric blood pressure as a determinant of the pain evoked in children during the injection (p>0.05). Conclusion: Crestal anesthesia proved an effective method to extract primary molars. However, further studies are necessary to confirm this

Therapeutic Effect of a Low-Level Laser on Acute Pain and Post-operative Mouth Opening After Closed Reduction of Mandibular-Condylar Fracture: Low-Level Laser Therapy in patients with closed reduction of mandibular-condylar fractur

Introduction: The aim of this study was to determine the therapeutic effect of low-level laser therapy on acute pain and the range of mouth opening after condylar closed-reduction surgery. The use of low-level lasers, especially to reduce inflammation and pain, has received more attention in recent years. The results of many studies performed in this field are contradictory, and the effectiveness of low-level lasers in the treatment of patients is still uncertain. Materials and Methods: This study was performed as a randomized, double-blinded clinical trial on 40 patients with condylar closed reduction surgery. Patients were randomly divided into two groups of 20 patients, including the placebo and intervention groups, in which the recent group received active low-level laser (100 mw, 2J/cm2, 20S/point, 14 extraoral points,7 days). The range of jaw movements after opening the intermaxillary-fixation was measured. Patients’ pain was measured using the visual analog scale (VAS). Data were analyzed using SPSS software version 21, the Chi-square test, and repeated measures ANOVA. Results: There was no significant difference between the study groups in terms of the range of jaw motion. Our results showed that at the end of the study, the mean pain score by VAS was 56.85 (SD = 1.387) in the intervention group and 60.95 (SD = 4.861) in the placebo group (P = 0.007). Conclusion: The results of this study indicated the effectiveness of low-level lasers in reducing acute pain in patients undergoing closed condylar surgery.
