Abstract:Background: Manual dexterity is important for dentists. However, few studies have investigated the relation between dental skills and manual dexterity. The hypothesis of the present study is that an association exists between manual dexterity and the accuracy of cavity preparation.Methods: Fifty-two dental students (25 males, 27 females) participated in this study. All subjects completed manual dexterity tasks (i.e., grip strength, pinch force, and number of taps made by fingers of the right hand) and a preparation accuracy test using Virtual Reality Systems (VRS, Simodont®). For the preparation test, the cross-block body in Simodont's Manual Dexterity section was used. The associations between erroneous preparations (i.e., errors in the lateral and vertical directions) and the results of manual dexterity tasks were then analyzed and examined.Result: The results revealed that grip strength and number of taps made by the fingers correlated with lateral direction errors. In particular, the number of taps in the first 10 s from the start of tapping made by the third finger, which the participants used as a finger rest during preparation, demonstrated a significant correlation with lateral direction errors.Conclusion: In this work, tapping was revealed to be associated with manual dexterity by quantifying the accuracy of preparation. In addition, the agility of the third finger used as a finger rest appeared to affect accuracy in the lateral direction. VRS is useful not only in developing teaching strategy but also in research on cavity preparation. DOI: 10.21276/aohdr.1828

Abstract:Introduction: In Head and neck squamous cell carcinoma (HNSCC), the clinical assessment of mandibular involvement is often inaccurate and unreliable. Involvement of mandible, upstage the disease to stage IV. Investigations like orthopantogram, computed tomography (CT), magnetic resonance imaging (MRI), bone scintigraphy etc have been evaluated by different authors for involvement of mandible with wide variation in results. This has prompted us to correlate clinically, radiological, and pathological to formulate the appropriate protocol for evaluation of mandibular involvement.Materials And Methods: It is a prospective and a retrospective study. In prospective part, all patients with clinical and radiological confirmation of mandibular involvement were undergone mandibulectomy. The histologic findings of mandibular bone involvement were then compared with the radiographic findings, along with tumor location, stage, and grade. For retrospective study, the medical records of patients, who had under gone mandibulectomy as a part of treatment of oral cavity cancers were analyzed and correlated. Results: In the present study, the bone involvement was found in 69% clinically, 40.5% by Orthopantogram, 39.6% by CT scan and 54% on MRI scan. The histological confirmation of bone involvement was evaluated in all the above cases. It was found that 22% of clinically positive, 46% of OPG positive patients, 52% of CT scan positive and 46% of MRI positive had invasionConclusion: There is no single modality of investigation which appears to have high specificity and sensitivity. Combination of different modalities increases the both sensitivity and specificity. In our study clinical examination along with high resolution CT scan has the acceptable sensitivity and specificity which may be applied for better results.

Abstract:Head and neck cancer constitute one of the most common cancer in India. Unlike western, it is associated with trismus and submucosal fibrosis in indian patients which makes the treatment more difficult. Irrational and inappropriate treatment leads to higher recurrence and mortality rate in india.

Abstract:Calcifying epithelial odontogenic tumor (CEOT) is a benign tumor of odontogenic epithelium.It is a locally invasive neoplasm with a characteristic feature of having amyloid. The mandible is twice more commonly affected than the maxilla and in the maxilla, posterior location is the preferred site of involvement. Here we present a case in a 50 years old male patient who presented with a non-tender hard swelling of the anterior maxilla measuring 2.5 x 1.5 cm, just right to the midline and at the base of the lateral incisor and canine. Imaging revealed a radiolucent lesion in the maxilla with small foci of calcification without any evidence of impacted tooth. Thus a provisional diagnosis of an Ameloblastoma was made. A local excision of the swelling was done along with extraction of the lateral incisor and canine. On histopathological examination, a diagnosis of Calcifying epithelial odontogenic tumor was rendered.DOI: 10.21276/aohdr.1807

Abstract:With the possibility of harnessing the regenerative potential of tissues, clinicians will find greater clinical instances where an old treatment modality used in conjunction with new materials gives greater clinical success in cases with poor clinical prognosis. This case typically illustrates such a situation where we successfully used MTATM in conjunction with an endodontic file used as an intracanal splint for repair of horizontally fractured root with minimal displacement of the fragments.

Abstract:Background Recently, various modifications in placing miniplates for direct fixation of the mandibular fracture are gaining popularity. The modifications have various advantages like more rigidity, less foreign material, less time in application, etc. Thus the purpose of this prospective study was to evaluate outcomes for three bone plating techniques used in the treatment of mandibular symphysis/ parasymphysis fractures.Methods A prospective study was conducted on 45 patients with mandibular symphysis/parasymphysis fractures and the patients were divided into 3 groups (A, B and C). Patients were followed for 3 months. Outcome parameters like occlusion, distraction of lower border radiologically, parasthesia, infection, failure of bone plate (plate fracture) and screw loosening, postoperative segmental stability and radiological evaluation of fixation were recorded.Results Distraction of lower border was seen in all the groups which were noticed radiographically at all follow ups. There was no occlusal discrepancy present in all the groups after three months post operatively. The fracture segments were stable in all groups at all times. Parasthesia was noticed in all the groups, which gradually decreased in one month and resolved completely by third month follow up. The degree of parasthesia, distraction of lower border, occlusal discrepancy was not statistically significant between the three groups. Hardware failure was not found in all the groups.Conclusion It can be concluded that conventional miniplate system is a better and easier method than the 3D miniplate system for fixation of mandibular fractures. In comparison, the 3D miniplate system is unfavorable for use in cases of oblique fractures and those involving the mental nerve, and is also difficult to adapt.
