Three-Dimensional Classification of Lower Third Molars and Their Relationship to the Mandibular Canal.
2021
PURPOSE To develop a novel classification making full use of radiographic three-dimensional (3D) information to describe the position, geometric configuration of a mandibular third molar (M3M) and its spatial relation to neighboring structures such as the mandibular canal (MC). The classification presented in this study helps to establish a common language and serves as a framework for further studies, for example, on 3D parameters influencing prognosis of the M3M and level of difficulty associated with its removal. MATERIAL AND METHODS A total of 8 parameters were included in the classification including position, the cranio-caudal height, the number of roots of the M3M as well as its spat…
Effect of the intra-alveolar administration of dexamethasone on swelling, trismus, and pain after impacted lower third molar extraction: a randomized…
2021
Background To evaluate the efficacy of intra-alveolar administration of dexamethasone 4 mg in the control of edema, trismus, and pain resulting from the extraction of impacted lower third molars and the drug permeability through the oral mucosa by in silico prediction. Material and Methods The randomized, double-blind, split-mouth clinical trial included patients who had both impacted lower third molars in equivalent positions. Hemiarches were divided into control side when dexamethasone was administered orally and experimental side when dexamethasone was administered using the intra-alveolar route. Patients were evaluated considering edema, trismus, and pain. The permeability of dexamethas…
Influence factors of dental anxiety in patients with impacted third molar extractions and its correlation with postoperative pain : a prospective stu…
2020
Background To explore the prevalence of dental anxiety (DA) in patients with third molar extractions and its influence factors and the correlation between DA levels and postoperative pain. Material and Methods A prospective and descriptive clinical study was performed. All patients who underwent the impacted third molar extraction from October 2017 to February 2019 were enrolled. DA levels were assessed by virtue of the modified dental anxiety scale (MDAS) and pain was assessed with a visual analog scale (VAS). Results A total of 150 patients were investigated and 136 valid questionnaires were retrieved, with an effective rate of 90.7%. The independent sample t-test and ANOVA results showed…
Efficacy of a topical gel containing chitosan, chlorhexidine, allantoin and dexpanthenol for pain and inflammation control after third molar surgery …
2020
BACKGROUND: The aim of this study was to evaluate and compare the postoperative effect of a topic gel containing chlorhexidine, chitosan, allantoine and dexpanthenol versus a placebo for pain and inflammation control after third molar surgery. MATERIAL AND METHODS: A gel combining 0.2% chlorhexdine, 0.5% chitosan, 5% dexpanthenol, 0.15% allantoin and 0.01% sodium saccharin was selected for this split mouth randomized controlled and double-blind trial including 36 patients with bilaterally and symmetrically impacted lower third molars. The teeth (n=72) were randomly divided into two groups before surgical removal: control group (CG; in which a placebo was given) and experimental group (EG). …
Influence of two different surgical techniques on the difficulty of impacted lower third molar extraction and their post-operative complications
2015
Background : Post-operative complications of various degrees of severity are commonly observed in third molar impaction surgery. For this reason, a surgical procedure that decreases the trauma of bone and soft tissues should be a priority for surgeons. In the present study, we compare the efficacy and the post-operative complications of patients to whom two different surgical techniques were applied for impacted lower third molar extraction. Material and Methods : Patients of the first group underwent the classical bur technique, while patients of the second group underwent another technique, in which an elevator was placed on the buccal surface of the impacted molar in order to luxate the …
Effect of preemptive dexamethasone and etoricoxib on postoperative period following impacted third molar surgery - a randomized clinical trial.
2019
Background The aim of this study was to compare the anti-inflammatory effects of dexamethasone and etoricoxib after third molar extraction. Material and Methods A prospective, randomized, controlled, split-mouth study was conducted. 19 volunteers were allocated randomly to receive 90mg etoricoxib 1 hour prior to the procedure or 4mg intramuscular dexamethasone immediately after anesthesia. Baseline measurements were obtained preoperatively, and subsequent assessments were made on immediate postoperative, at 72 hours and 7 days after surgery to measure postoperative facial swelling by use of linear measurements, interincisal mouth opening width and visual analog scale score for pain. The amo…
The effects of a topical gel containing chitosan, 0,2% chlorhexidine, allantoin and despanthenol on the wound healing process subsequent to impacted …
2016
Background Despite efforts to prevent postoperative discomfort, there are still many immediate side effects associated with the surgical extraction of impacted lower third molars. Cicatrization is a physiological process through which the loss of integrity of oral mucosa is recovered and damaged tissues are repaired. Bexident Post (ISDIN, Spain) is a topical gel that contains chitosan, 0.2% chlorhexidine, allantoin and dexpanthenol. While this gel has many clinical indications, there are no published clinical trials evaluating its use in impacted mandibular third molar surgery. This study aims to clinically evaluate the efficacy of a gel containing chitosan, 0.2% chlorhexidine, allantoin an…
Effect of antibiotic prophylaxis for preventing infectious complications following impacted mandibular third molar surgery. A randomized controlled t…
2021
Background The objective of this study was to determine the effect of antibiotic prophylaxis in preventing postoperative infections after extraction of impacted mandibular third molars. Material and Methods A Parallel-group, randomized, blind, placebo-controlled trial was performed. 154 patients were randomly allocated to 2 groups; experimental (n=77) receiving 2g amoxicillin 1 hour prior to surgery and control (n=77) receiving placebo. Primary outcome was postoperative infections and secondary outcome was the need for rescue analgesia. Results 4.5% of patients developed postoperative infections, five patients of the control group (4 alveolar osteitis, 1 surgical site infection) and two of …
The effect of triangular and reversed triangular flap designs to post third molar odontectomy complications (a pilot study)
2020
Background Odontectomy is one of the most common surgical procedures in oral and maxillofacial surgery. Flap design influences the post operative complications. Triangular flap is the most widely used flap design but it has many shortages such as dehiscence, alveolar osteitis, reactionary bleeding, and periodontal disruption distal of second molar. The aim of this study is to introduce an alternative flap design in the surgical removal of impacted mandibular third molars – reversed triangular flap – and to compare this flap design with the triangular flap in case of dehiscence, reactionary bleeding, and clinical attachment loss. Material and Methods This prospective, split-mouth study invol…
Pericoronitis: A clinical and epidemiological study in greek military recruits
2019
Background This paper presents a statistical analysis of epidemiological, clinical and radiographical characteristics of third molar-related pericoronitis. Material and methods 650 conscripts of the First Training Division of Conscript Soldiers of 2005 in Greece were recruited for the study. Each conscript was given a questionnaire and underwent a clinical test and a radiographic examination. The tested variables included the conscripts' personal information, oral hygiene parameters along with the radiographic angulation of the third molar, the level of impaction and their classification in relation to the edge of the mandible. Results The prevalence of pericoronitis was found to be 4.92%. …
