RESUMO
INTRODUCTION: Tooth extraction is still one of the most common dental procedures, routinely performed for a variety of reasons. Tooth extraction forceps and elevators are well-known extraction instruments which have been the standard in tooth extraction procedures for well over a hundred years. Physics forceps are one possible alternative, aiming to perform less traumatic and more predictable extractions.

RESUMEN: Introducción: Tradicionalmente la osteotomía requerida en la exodoncia de terceros molares mandibulares incluidos o semi-incluidos ha sido realizada con instrumental manual o rotatorio. Con el advenimiento de la técnica ultrasónica de la cirugía piezoeléctrica, se hace necesario comparar la seguridad y efectividad de ambas técnicas. Métodos: Realizamos una búsqueda en Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante el cribado de múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, analizamos los datos de los estudios primarios, realizamos un metanálisis y preparamos una tabla de resumen de los resultados utilizando el método GRADE. Resultados y conclusiones: Identificamos ocho revisiones sistemáticas que en conjunto incluyeron 22 estudios primarios, de los cuales 12 corresponden a ensayos clínicos aleatorizados. Concluimos que el uso de instrumental piezoeléctrico en comparación con el instrumental rotatorio convencional podría aumentar el tiempo quirúrgico y podría disminuir el dolor temprano y tardío, junto con el edema al día siete, pero la certeza de la evidencia es baja. Por otra parte, el uso de instrumental piezoeléctrico podría resultar en poca o nula diferencia en el desarrollo de alteraciones neurológicas postoperatorias ya que la certeza de la evidencia es baja. Además, el uso de piezoeléctrico probablemente resulte en poca o nula diferencia en la apertura bucal.
ABSTRACT: Introduction: Traditionally, osteotomy techniques required in exodontia of included or semi-included mandibular third molars has been performed with manual or rotary instruments. With the advent of the ultrasonic technique of piezoelectric surgery, it is necessary to evaluate the effectiveness and safety of both osteotomy techniques. Methods: We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed primary studies' data, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. Results and conclusions: We identified eight systematic reviews that together included 22 primary studies overall, of which 12 were randomized trials. We conclude that the use of piezoelectric surgery compared with conventional rotary instruments may increase operative time and reduce early and late pain, along with edema at day seven, but the certainty of the evidence is low. On the other hand, the use of piezoelectric instrumentation may result in little or no difference in the development of postoperative neurologic disturbances as the certainty of the evidence is low. Also, piezoelectric use probably makes little or no differences in mouth opening.

Minimally traumatic tooth removal is the norm for removing teeth when a dental implant is planned at that site. The quantity of available bone is the primary requisite to place an implant. The initial use of a scalpel blade to widen the periodontal space followed by the use of luxators is one of the techniques that is being followed for atraumatic extraction. A case of accidental breakage of a number 11 scalpel blade while attempting tooth removal and the method adopted in removing this portion of the blade without further bone destruction is reported here. The authors have not found any previously published cases, reporting the breakage of a scalpel blade during the bone expansion procedure and its management.

Third molar extraction is a common oral surgery performed in the pediatric population. Here we report a case of extensive subcutaneous emphysema of the orbital, masticator, parapharyngeal, retropharyngeal spaces, bilateral carotid and visceral spaces, and pneumomediastinum after third molar extraction with turbine drill. This was treated with intubation for airway protection, transoral drainage, and intravenous antibiotics. After discharge the patient reported persistent dysphonia and was found to have left vocal fold paresis. This was likely related to extensive pneumomediastum causing injury to the recurrent laryngeal nerve. This is the first report of cervicofacial emphysema leading to vocal cord paresis after third molar extraction, demonstrating the importance of serial clinical monitoring in these cases.

During surgical third molar removal and coronectomy procedures, tooth sectioning is an important and, in some cases, an inferior alveolar nerve-endangering step. This article introduces a drilling sleeve that was printed according to the individual tooth-sectioning situation preoperatively, using diagnostic cone-beam computed tomography data. Not only did the sleeve function in our case as a mark on the drill; it was also a reliable physical limiter, serving as a determinant of the required depth during tooth sectioning. This fast and cost-effectively produced drilling sleeve may help younger colleagues when the depth of tooth sections should be precisely controlled.

Deep neck infection is life-threatening and mortal condition that requires immediate treatment. This infection is generally polymicrobial and frequently seen after upper respiratory infections, poor dental hygiene, trauma and surgery to the head and neck region. The symptoms of deep neck infections are swelling, dysphagia, pain, trismus, dysphonia and otalgia. Deep neck infections can be seen at any age and its mortality is about 20-50%. Initial management of the deep neck infection is intravenous antibiotic, protection of airway and drainage of abscess. Deep neck infections can cause severe complications even dead can be seen, so physicians should be aware of these complication. Herein, we reported a 71-year-old-woman suffering from traumatic deep neck infection due to pulling a tooth with pliers.

Surgical emphysema is a rare complication of dental extractions, often associated with the use of high-speed air rotors. This report describes a case of extensive surgical emphysema following a simple surgical extraction of a LL6 under local anaesthetic. There was no use of air-driven handpieces during the procedure. The patient developed extensive surgical emphysema bi-laterally in both cervical neck and facial planes. After prophylactic antibiotics with careful monitoring in a secondary care setting, the patient made a full unremarkable recovery. Clinical relevance: Simple extraction of teeth is a procedure carried out daily by most general dental practitioners. However, the risk of surgical emphysema without the use of high-speed air rotors or instruments using pressurized air/water is not well known or documented.

Surgical removal of impacted mandibular third molar is a routine procedure in oral surgery. Various iatrogenic complications related to the procedure has been discussed well in the literatures before. Some of these complications are related to the wrong usage of instruments and techniques. Here we discuss a rare complication on a 42-year-old male, related to the use of high-speed handpiece drill in mandibular third molar removal in a general dental office setting. He was referred when a high speed tungsten carbide bur was accidentally broken and displaced into the mandibular bone during surgical procedure. It is not common to use a high-speed handpiece in impacted third molar removal. This iatrogenic complication could have been totally avoided with the use of proper equipment and technique; therefore raising awareness regarding wrong usage of instrument is vital to avoid similar incidents in the future.

Dental injection needle breakage is an uncommon problem in dental practice. Displacement of the broken fragment into anatomical spaces is, on the other hand, a serious complication that occurs most commonly during inferior alveolar nerve blocks as a result of material wear, incorrect application of the anesthesia technique, or sudden movement of the patient during injection. Further complications such as infection, trismus, and nerve paralysis may exacerbate the condition and, if not treated adequately, life-threatening conditions may develop over time as the fragment dislodges deeper in soft tissues. Clinical symptoms of the patient, as well as the findings gathered from detailed physical examination and radiographic evaluation, are important factors to consider before performing an exploratory surgery. Removal of a broken needle may be troublesome due to its proximity to vital anatomic structures. Multislice computed tomography is a reliable imaging modality that provides accurate information to pinpoint the exact location of the needle fragment.This report describes a case of needle breakage occurred during inferior alveolar nerve block which was performed to extract a third molar tooth and the migration of the broken fragment from the right mandibular ramus area into the perivertebral space, with special emphasis on the surgical retrieval technique with multiplanar computed tomography imaging guidance.

PURPOSE: We performed a retrospective review of in-office removal of complex mandibular third molars with a dynamic image navigation system (DINS). MATERIALS AND METHODS: A retrospective review was conducted of cases completed from 2010 to 2014 by a single oral and maxillofacial surgeon. The average age of the patients was 47 years (range, 27 to 72 years). Extraction complexity was classified with Juodzbalys and Daugela's classification system. The included study cases had complexity scores of 9 or greater. Each patient received custom intraoral splints to secure the tracking array and underwent cone beam computed tomography image acquisition. All surgical procedures were performed with a precalibrated tracking straight handpiece under dynamic navigation. RESULTS: All 25 cases were treated successfully with the use of the DINS. Twelve of these cases were associated with pathologic lesions. Three patients were noted to have inferior alveolar nerve paresthesia. One patient sustained a pathologic fracture at week 2. Postoperative infections were noted in 7 cases, 2 of which had a pre-existing infection. One patient reported temporary limitation of mouth opening. A coronectomy was performed in 1 case. CONCLUSIONS: We present results using a new technology, the DINS, for removal of complex mandibular third molars. Potential advantages are 1) improved visualization and localization of anatomic structures such as the inferior alveolar nerve, lingual cortical plate, and adjacent roots; 2) improved control during osteotomy; 3) decreased surgical access requirements and reduction in overall bone removal; 4) ability to perform complex procedures successfully in an in-office setting; 5) decreased surgical time resulting from improved visualization; and 6) potential use as a teaching tool. Possible limitations of the use of an in-office DINS include increased cost, increased time attributed to presurgical planning, initial learning curve, and optical array interference by the surgeon or assistants during surgery.

PURPOSE: To investigate the appropriate endodontic file for the extraction of root tips through a biomechanical study and to evaluate the clinic efficiency of this technique. MATERIALS AND METHODS: Nine hundred molar roots were randomly divided into 3 groups (3, 5, and 7 mm) and amputated to the corresponding length. Different files were inserted into the root tips, and a pullout test was conducted using a universal testing machine. The pullout force was recorded and files with greatest pullout force were selected for clinical study. Patients' root tips were extracted using these files. The duration and incidence of postoperative complications were recorded. RESULTS: The greatest pullout force was obtained for the 25# Hedström file, regardless of the length of the root tip and the type of file. The pullout force of Hedström files was significantly greater than that of Kerr files in each file group and root length group (P < .05). Clinically, the direct success ratio of this technique was 81.4%. The incidence of postoperative complications was very low. CONCLUSION: The results of this study suggest that the application of endodontic files for the extraction of root tips is an acceptable technique. The 25# Hedström file is the optimum choice for root extraction in most cases when using endodontic files.

The aim of this study was to evaluate the influence of the residual root and peri implant bone dimensions on the clinical success of the socket shield technique. Thirty-six dental implants were installed in 6 dogs. The clinical crowns of teeth P3, P4 and M1 were beheaded. Afterwards, the roots were worn down 2-3mm in apical direction until they were located at crestal level. Posterior implant beds were prepared in the center of the roots passing by 3mm apically forming 6 groups in accordance to the remaining root thickness. Radiography of the crestal bone level was performed on day 0 and after 12 weeks. Histomorphometric analyses of the specimens were carried out to measure the crestal bone level, the bone to implant contact and the buccal and lingual bone thickness at the implant shoulder portion. Correlations between groups were analyzed through nonparametric Friedman test, statistical significance was set as p<0.05. All 36 implants were osseointegrated, but 3 samples showed a clinical inflammatory reaction and some radicular fragments presented a small resorption process. On the buccal and lingual side, the radicular fragment was attached to the buccal bone plate by a physiologic periodontal ligament. In the areas where there was space between the implant and the fragment, newly formed bone was demonstrated directly on the implant surface. Within the limitations of an animal pilot study, root-T belt technique may be beneficial in preserving and protecting the bundle bone and preservation of soft tissues. If the thickness of the buccal bone is 3mm, and the thickness of the remaining root fragment is 2mm, the socket shield technique is more predictable and the bone contours can be maintained.

BACKGROUND/AIM: Suture materials play an important role in healing, enabling reconstruction and reassembly of tissue separated by the surgical procedure or trauma, and at the same time facilitating and promoting healing and hemostasis. Suture materials are used daily in oral surgery, and are considered to be substances most commonly implanted in human body. The aim of this clinical study was to examine the speed of wound healing and complications incidence, after the use of three different absorbable synthetic suture materials in oral surgery (catgut, Dexon and Vicryl rapide), and to ascertain which one is the most suitable for oral surgery. METHODS: The study was conducted on 96 patients undergoing root resection or surgical extraction of third molars. Each of the suture materials (catgut, Dexon and Vicryl rapide) was used for 8 root resections and 8 surgical third molar extractions in the maxilla, as well as in the mandible (a total of 32 surgical interventions for each suture material). RESULTS: The faster wound healing was obtained with Vicryl rapide compared to other two suturing material tested. There was no significant difference regarding the presence of local reaction in all the three groups of patients on the 21st postoperative day. CONCLUSION: The results of our clinical study point out that Vycril- rapid contributes more than catgut or Dexon to faster healing of human wounds, with fewer incidences of wound dehiscence and milder local reactions.
