ABSTRACT Aim The aim of this study is to evaluate the effect of demographic, clinical, and radiographic factors on the duration of surgical extraction of impacted lower third molars. Materials and methods This retrospective study included patients who underwent surgical removal of impacted lower third molars, and the investigated factors were demographic data including age and gender, radiographic data including the impacted tooth angulation and depth of impaction and ramus relation, and clinical data including the state of eruption of the impacted teeth. These factors were evaluated for association with the duration of surgery. Descriptive statistical analysis included percentages and mean ± standard deviation (SD). Student's t-test was used to compare means between two groups, while for comparing the means among three or more groups for statistical significance, analysis of variance (ANOVA) test was used. Results Forty patients were included: 20 (50%) males and 20 (50%) females. The age range was from 17 to 37 years with a mean ± SD of 23.4 ± 5.016 years. The duration of surgery (± SD) in all the patients ranged from 10 to 40 minutes with a mean of 25.8 ± 8.56 minutes. Clinically unerupted teeth and deep ramus relationship were associated with statistically significant increase in duration of surgical extraction. Conclusion This study identifies state of eruption and ramus relation to be significant predictive factors, whereas other investigated factors, namely, age of patient, sex, angulation of teeth, and depth of impaction, were found to be not significant in determining the duration of surgery and hence, the difficulty of extraction. Clinical significance Duration of surgical extraction of impacted mandibular third molars can be considered as an indicator for difficulty of surgical extraction. Difficult surgical extraction of impacted mandibular third molars can be anticipated in clinically unerupted teeth and those with deep ramus relationship. How to cite this article Bede SY.

The purpose of this study was to test the effect of the surgical removal of impacted mandibular third molars using piezosurgery versus the conventional surgical technique on postoperative sequelae and bone healing.Material and Methods.This study was carried out as a randomized controlled clinical trial: split mouth design. Twenty patients with bilateral mandibular third molar mesioangular impaction class II position B indicated for surgical extraction were treated randomly using either the piezosurgery or the conventional bur technique on each site. Duration of the procedure, postoperative edema, trismus, pain, healing, and bone density and quantity were evaluated up to 6 months postoperatively.Results.Test and control sites were compared using pairedt-test. There was statistical significance in reduction of pain and swelling in test sites, where the time of the procedure was statistically increased in test site. For bone quantity and quality, statistical difference was found where test site showed better results.Conclusion.Piezosurgery technique improves quality of patient’s life in form of decrease of postoperative pain, trismus, and swelling. Furthermore, it enhances bone quality within the extraction socket and bone quantity along the distal aspect of the mandibular second molar.

Background and objective: Administration of some additives with local anesthetics can prolong pain free period post-operatively, thereby reducing need for post-operative analgesics and improving patient comfort. Potassium chloride was found to increase duration and quality of anesthesia in various studies on brachial plexus blockade. This study was designed to evaluate and compare the effect of 2% lignocaine with 1.5% potassium chloride, 2% lignocaine with adrenaline and 2% lignocaine (plain) in pterygomandibular nerve blocks. Materials and methods: A triple blind randomized controlled study was conducted on 120 adults, aged 18–45 years in ASA-I category, requiring surgical extraction of impacted mandibular third molars. The subjects were divided equally into 3 groups randomly by computer generated sequence; Group 1: 2% lignocaine plus 1.5% solution of potassium chloride, group 2: 2% lignocaine with 1:80,000 adrenaline and group 3: 2% plain lignocaine. Onset, duration, depth (pain) of anesthesia, patient satisfaction, systolic and diastolic blood pressures, heart rate and oxygen saturation, were evaluated and compared. Results: Onset was shortest for group1 and longest for grp3, statistically highly significant difference between the 3 groups (p < 0.01). Statistically significant difference (p < 0.05) was found in duration of surgery, duration of analgesia and VAS scores between groups 1 & 3. Duration and depth of anesthesia were comparable for groups 1 & 2. There was no statistically significant difference seen for total amount of dose used, SBP, DBP, HR and SpO2 between the 3 groups (p > 0.05). Conclusion: Potassium chloride, a physiological salt is inert and causes no local/systemic adverse effects when injected with lignocaine in physiologically permissible amounts. The combination achieves satisfactory onset, duration, depth of anesthesia without altering hemodynamic variables. Hence, it may be considered as a safe and effective additive.

Abstract Aim The aim of this study was to assess the relative contributions of patient characteristics and radiographic variables to the difficulty of extraction of impacted mandibular third molars in a Nigerian population. Methods and Materials Seventy-nine consecutive patients undergoing mandibular third molar extractions were recruited for this prospective cohort study. Specific patient characteristics and radiographic variables were recorded. All extractions were performed under local anesthesia by the same oral surgeon, and the surgical difficulty was assessed based on the duration of surgery. Results Body weight (BW) (P=0.009) and body surface area (BSA) (P=0.004) were the significant patient characteristics while tooth impaction depth (P=0.002), number of roots (P=0.035), and tooth angulation (P=0.003) were the significant radiographic variables associated with surgical difficulty using a univariate analysis. A multiple linear regression model was constructed with these variables using surgical difficulty as the dependent variable. Radiographic factors were found to be the more important determinants of surgical difficulty with the depth of impaction (P=0.038) being the singular most important factor. Conclusion Although the difficulty of surgical removal of impacted lower third molars is dependent on BW, BSA, impaction depth, tooth angulation, and the number of roots, radiographic variables were of greater importance with impaction depth being the most important single factor.

The aim of this study was to evaluate the clinical reliability of the Pederson index in preoperative assessment of the difficulty of surgical removal of impacted mandibular third molars. Pederson index was found to be unreliable predictor of true difficulty with low sensitivity and specificity. A new index (Kharma scale), which takes into consideration the anatomical form of tooth roots, is proposed and evaluated both pre- and postoperatively. The results of the evaluation indicate that the new estimating index is more reliable and accurate measure than Pederson scale.

Due to the frequent development of non-infectious complications after surgical removal of the third lower impacted tooth, many techniques are used to reduce their severity. Among them is the technique of applying platelet-rich fibrin to the post-extraction alveolus. The study included 90 consecutively enrolled patients. Eligible patients were randomly assigned to two groups: patients with and without platelet-rich fibrin introduced into the postoperative alveolus. Pain, swelling, trismus, and temperature were evaluated after the procedure. Pain intensity was significantly higher in the control group than in the study group at 6 h, 1, and 3 days after surgery. PRF application did not significantly affect the intensity of swelling. Body temperature was significantly higher in the control group than the study group on day two after surgery. The trismus was significantly higher in the control group than in the study group at one, two, and seven days after surgery. Application of the PRF allows for a faster and less traumatic treatment process. It will enable for speedier recovery and return to active life and professional duties.

Introduction: Diagnosis and management of impacted mandibular third molars call for a cogent appraisal and treatment choice both for the sick person and the dental practitioner. This academic work scrutinized the pattern as well as treatment of impacted mandibular third molars at the Teem Clinic and Dental Centre, Ekpan, Delta State, in Nigeria.Materials and Methods: This cross-sectional survey involved 131 cases who reported impacted mandibular third molars. The age, gender, impacted tooth, type of impaction, pathological conditions, and treatment proffered were recorded.Results: The male to female ratio was 0.8:1, with an age range of 10 to 40 years. Of the lower third molar impactions 58 (42.0%) were mesioangular, 5 (3.6%) horizontal, 18 (13.0%) vertical and 57 (41.3%) were distoangular. A total of 47 (34.1%) quested for dental attention following varying degrees of pain induced by pericoronitis. Teeth removal was accomplished for 76 (55.0%) owing to carious lesions on the impacted teeth, proximate tooth, or both. Surgical extraction was the option taken in 69 (50.0 %) with caries on the impacted teeth while 3 (2.2%) had to pull out of their teeth done owing to carious lesions on the bordering second molars. In 3 (2.2%) both the impacted third molar and the proximate second molar were decayed. Conclusions: The prevailing indication for pulling out impacted mandibular third molars was acute pericoronitis. Mesioangular sort of impaction was most recurrent and ought to be considered for theplausibility of frequentness of complications.
