CHA-collagen implantation to increase alveolar bone density

Tooth extraction is the common procedure in dentistry. This procedure causes a wound in teeth socket. Thus, the socket had to be secured to prevent over resorption of alveolar bone. This study used the third molar as a model to examine the third molar mandibular odontectomy routine procedure in oral and maxillofacial surgery. The new bone formation could be evaluated by radiographic examination. The aim of this study was to evaluate the effect of CHA-collagen implantation on the third molar mandibular bone density using 3D-CBCT to determine bone quality. The research was conducted by comparing extraction socket after the third molar mandible odontectomy, before and after graft material implantation. The subjects were divided into two groups. Group A consisted of six non-implanted subjects and group B consisted of six subjects with CHA-collagen implanted socket. Three dimensional CBCT evaluated alveolar bone density using pixel intensity at the socket area after odontectomy procedure and 10 weeks after. The result of t-test showed that CHAcollagen implanted socket had significantly higher pixel intensity than non-implanted group (p=0,046) until 10 weeks. Spearman test showed that the implanted CHA-collagen had a positive correlation with the increase of alveolar bone density (p=0.028; r=0.860) until 10 weeks. In brief, implantation of CHA-collagen increased bone density until 10 weeks.

Various biomaterials are currently used for bone regeneration, with autogenous bone being considered the gold standard material because of its osteogenic, osteoconductive, and osteoinductive properties. In recent years, the use of autogenous dentin as a graft material has been described. This split-mouth clinical trial assesses the efficacy of autogenous dentin for the regeneration of periodontal defects caused by bone loss associated with impacted lower third molar extraction. Fifteen patients underwent bilateral extraction surgery (30 third molars) using dentin as a graft material on the test side, and leaving the control side to heal spontaneously, comparing the evolution of the defects by evaluating probing depth at three and six months post-operatively. Bone density and alveolar bone crest maintenance were also evaluated six months after surgery, and pain, inflammation, mouth opening capacity on the second and seventh days after surgery. Probing depth, radiographic bone density, and alveolar bone crest maintenance showed significant differences between the test and control sides. Autogenous dentin was found to be an effective biomaterial for bone regeneration after impacted lower third molar extraction.

Mandibular Third Molar

Third molar extraction is one of the most commonly performed minor surgical procedure in any dental practice worldwide, often accompanied by various postoperative sequelae such as swelling pain and trismus which intern affects the quality of life of a patient. Over the past few decades, different methods have been proposed in the literature and were clinically evaluated to reduce the postoperative discomfort after mandibular third molar impaction and out of which corticosteroids, have shown promising results. Dexamethasone (administered either orally, submucosally, IV or IM), methylprednisolone acetate and methylprednisolone sodium succinate (IV or IM or submucosal) are most commonly preferred corticosteroids in oral and maxillofacial surgery. The main objective is to systematically review the comparison of the effectiveness of submucosal administration of dexamethasone with methylprednisolone following mandibular third molar impaction in reducing the postoperative sequelae, and its discomfort and searches were performed in the PubMed, Medline, Scopus, and Cochrane Library databases. Two articles were most relevant, and the results of the comparison of the selected articles were analysed. From this deliberate audit, it is very well may be inferred that submucosal injection of dexamethasone plays a promising role in reducing the postoperative sequelae which includes swelling, pain and trismus and its discomfort following mandibular third molar impaction when compared with that of methylprednisolone.

Surgical Difficulty

The extraction of impacted third molars is among the most common surgical procedures carried out in the field of Oral and Maxillofacial Surgery. Both the patient and dentist must therefore have scientific evidence-based information concerning the estimated level of surgical difficulty of every case to consider in referring cases of impacted third molars for specialists’ handling. We have undertaken a study in which demographic and radiological variables were considered together to evaluate the risk factors for surgical difficulty in a cohort of 100 impacted mandibular third molars. There were 13 variables evaluated for surgical difficulty. Total surgical time intervention was noted at the end of each surgery. Each variable was analysed with total surgical time intervention with univariate and multiple linear regression. Out of 13 variables, 9 were found statistically significant. The most significant predictors for surgical difficulty were Body Mass Index, Depth of impacted tooth and Retromolar space. No postoperative complications were reported.

Third Molar Eruption

Third molars are highly variable in their presence and form. This report focuses on a horizontally impacted third molar and analyzes the potential etiology of this situation. Upon a clinical and radiographic examination, it was noted that the patient had four third molars present. The patient’s third molars began erupting around the age of 19. Currently, they are asymptomatic with incipient caries on the occlusal surfaces. While three of the third molars erupted in a normal orientation, one of the third molars (mandibular left) erupted in an orientation that would be classified as horizontal and/or mesio-angular. No treatment has been undertaken at the moment, however surgical extraction can be recommended with the prognosis being very good. For the clinician that has to treat dental complications that arise from abnormal tooth eruption, as seen in numerous genetic and acquired disorders, knowledge about the basic molecular mechanisms involved may become extremely important.

Introduction: Surgery of mandibular third molar teeth for removal is one of the most common procedures undertaken in oral and maxillofacial surgery departments. The complications created by the post extraction wound healing and physiological consecution of third molar surgery can affect patients' quality of life. Platelet rich plasma (PRP) is an autologous concentrate of platelets suspended in the Plasma that accelerates healing by concentration of growth factors which lessen the inflammation and as a result pain and trismus. Materials and methods: A Study was conducted on 130 patients at the department of Oral and Maxillofacial Surgery, FUCD Islamabad, for a period of 6 months after ethical approval. The patients with impacted mandibular wisdom teeth were selected and divided equally into two equal groups. The pain score was measured using the visual analogue scale (VAS) and trismus was measured using Vernier caliper before the surgery, immediately after surgery, on 3rd and 7th follow up visits. Results: The mean postoperative pain on 7th day was significantly lower in the PRP group with statistically significant P-value <0.0001. Trismus was also less reported in the PRP group with P-value <0.00065. Conclusion: Platelet Rich Plasma is effective to lessen trismus and pain after surgical removal of mandibular third molar teeth.

Mandibular Third Molars

Extraction of mandibular third molars is a common procedure in oral and maxillofacial surgery. There are studies that simultaneously predict the extraction difficulty of mandibular third molar and the complications that may occur. Thus, we propose a method of automatically detecting mandibular third molars in the panoramic radiographic images and predicting the extraction difficulty and likelihood of inferior alveolar nerve (IAN) injury. Our dataset consists of 4903 panoramic radiographic images acquired from various dental hospitals. Seven dentists annotated detection and classification labels. The detection model determines the mandibular third molar in the panoramic radiographic image. The region of interest (ROI) includes the detected mandibular third molar, adjacent teeth, and IAN, which is cropped in the panoramic radiographic image. The classification models use ROI as input to predict the extraction difficulty and likelihood of IAN injury. The achieved detection performance was 99.0% mAP over the intersection of union (IOU) 0.5. In addition, we achieved an 83.5% accuracy for the prediction of extraction difficulty and an 81.1% accuracy for the prediction of the likelihood of IAN injury. We demonstrated that a deep learning method can support the diagnosis for extracting the mandibular third molar.

Background and Objectives: Large radicular cysts of the maxilla present a clinical challenge, as they may cause recurrent infection, severe alveolar bone loss and disruption of the nasal and maxillary sinus floors. The aim of this study was to evaluate the effect of previous root canal treatment on the clinical presentation of large maxillary radicular cysts. Materials and Methods: All cases of radicular cysts treated at the Oral and Maxillofacial Surgery Department of a tertiary public hospital over a period of six years (2012–2018) were evaluated. Histologically confirmed radicular cysts of the maxilla with a maximal dimension of over 15 mm were included. Demographic data of the patients, clinical presentation and radiographic features of the lesions were analyzed. Results: A total of 211 inflammatory cysts were treated in the study period, of these 54 histologically diagnosed radicular cysts in the maxilla were found to have a maximal dimension of over 15 mm. The mean age of patients with large maxillary radicular cysts was 43.3 years, 57.6% of which were male and 42.4% female. The lateral incisor was the most common tooth affected (46.3%). The mean size of the large radicular cysts was 25 mm. Then, 83.8% of the cysts were observed in teeth with previous endodontic treatment. Teeth without endodontic treatment presented clinically with significantly fewer acute symptoms in comparison to teeth with previous endodontic treatment. Conclusions: the vast majority (83.8%) of large maxillary radicular cysts were associated with endodontically treated teeth. Previous endodontic treatment was correlated to increased frequency of clinical symptoms.
