Over the past three decades, little scientific progress has been made relative to occlusion in conventional complete dentures. Equal distribution of functional load throughout the residual denture foundation is likely an important factor in prosthesis stability and patient acceptance of dentures. A better understanding the relationship between denture occlusion and the physiologic behavior of muscles involved in mastication may prove beneficial in the clinical management of edentulism. The purpose of the present study was to determine the short-term immediate effects of unilateral and bilateral posterior occlusal interferences on masticatory muscle activity in edentulous patients treated with conventional complete dentures. Bilateral EMG activity of the anterior temporalis and masseter muscles was recorded in ten subjects at baseline, following introduction of unilateral posterior occlusal interferences, and following introduction of bilateral posterior interferences. During each experimental event, muscle activity was recorded bilaterally at maximal clench and the intended denture occlusion was electronically verified. Patients responded to questionnaires after each experimental intervention and following removal of occlusal interferences. Student’s paired t-test was used to compare the data obtained (p = 0.05). Results indicate no significant difference in EMG values at baseline, after introduction of bilateral posterior interferences, after the introduction of unilateral right posterior interferences and after removal of the occlusal interference. In the group with unilateral left posterior occlusal interferences there was a significant reduction in the EMG activity of the left masseter. Analysis of questionnaires did not reveal any significant findings. Taken together, results suggest that there was no significant difference in the EMG values of the patient after the introduction of the posterior interferences.

Aim: The aim of this study was to evaluate the stress developed in the bar connecting implants and in the mandible as a result of the elastic deformation of the mandible during mouth opening when using a finite element method (FEM). Materials and methods: A three-dimensional model of an edentulous mandible was generated based on the computer tomography (CT) data of a patient. Two cylindrical implants (diameter 4.3 mm, length13 mm) were inserted in the area of the mandibular canine, premolar and molar in the mandibular model. Implants were connected with a rigid bar (width 2 mm, height 3 mm), and mouth opening was simulated on the threedimensional (3D) model. The location and magnitude of maximum von Misess stress that occurred in the mandible and in the bar were estimated. Results: The highest stress level in the mandible (4.5 GPa) and in the splint (32 GPa) was measured in the longest fixed partial denture with the implants in the mandibular left canine and left second molar position. The maximum stress in the bone was measured distal to the splinted implants. Conclusion: Since, great distance between splinted implants caused high stress during mouth opening, due to mandibular deformation, the use of a short span fixed partial denture supported by implants in the molar region of the edentulous mandible is probably more advantageous.

Aim: The study was outlined to determine and assess the C-reactive protein (CRP) level in chronic periodontitis patients and to assess the CRP values after using Dental Air Force home dental cleaning system. Materials and methods:A total of 100 adult chronic periodontitis subjects were recruited voluntarily for this study. Clinical assessment of plaque index, gingival index, probing depth, clinical attachment level and C-reactive protein (CRP) levels were made prior to phase-1 therapy and at 7th and 15th day posttherapy. Effects of treatment were assessed by paired tests and analysis of variance by treatment group with baseline covariates. Comparative assessments were done among all the patients that were divided into four groups. Results: The results of this study showed that there was 35% decrease in CRP level in periodontitis patients that used Dental Air Force home dental cleaning system without undergoing phase 1 (complete scaling and root planing) therapy. There was 100% decrease in CRP in group D (phase 1 therapy followed by use of Dental Air Force home dental cleaning system) as compare to group C (phase 1 therapy followed by use of toothbrush) where there were 89.61% decrease in CRP level from baseline to 15th day of recordings. Conclusion: There was strong correlation between periodontal diseases and CRP level and as there is progression and remission of periodontal disease; CRP values follow the same. Dental Air Force home dental cleaning system with the access to interdentally area helps in preventing the accumulation of dental plaque biofilm, thus able to maintain the CRP at lower levels as compare to traditional toothbrushing.

Odontomas behave more like developmental abnormalities (hamartomas) than true neoplasms. Odontomas are developmental anomalies resulting from the growth of completely differentiated epithelial and mesenchymal cells that give rise to ameloblast and odontoblast. Odontomas are classified as complex odontoma and compound odontomas. The purpose of the article is to enumerate the diagnostic criteria for odontomas.

Background: Cellular angiofibromas are rare benign mesenchymal neoplasms characterized by spindle cell component and numerous small vessels. They are commonly well-circumscribed, localized in the superficial soft tissues. The lesion is more frequently seen in the inguinoscrotal or vulvovaginal regions and occurs equally in men and women, and rarely involves oral cavity. Due to its clinical and histological similarity with other mesenchymal tumors, such as angiomyoma, hemangioma, lymphangioma and hemangiopericytoma, angiofibroma presents a diagnostic dilemma. Case report: Very few cases of angiofibroma involving maxillofacial region have been reported in the literature. This case report involves cellular angiofibroma involving left buccal mucosa in a 23-year-old female patient. Following detailed clinical examination, radiological interpretation and histopathological diagnosis, surgical excision was performed. The patient was followed-up on a regular basis and was disease free. Summary and conclusion: Benign angiofibroma involving oral cavity is a rare tumor. There is a close resemblance of this tumor with other mesenchymal lesions and, thus, faces a diagnostic challenge. Surgical excision with a long-term followup gives good prognosis to this lesion—benign cellular angiofibroma. Keywords:Angiofibroma, Mesenchymal tumor, Oral soft tissue swelling.

Background: Third molars are one of the most commonly impacted teeth in the oral cavity. But in very rare cases, the impacted molars can be inverted as well. In this case, the patient presented with an inverted and impacted left maxillary third molar. The aim of the operating surgeon was to execute the procedure in the least hazardous manner, to avoid any surgical complications. Methods: The surgical extraction of the tooth by lateral transposition method was carried out rather than the classical method owing to the inverted position of the impacted tooth. The surgery was carried out under local anesthesia. An incision was made at the crest of the ridge with an anterior releasing incision. Bone overlying the impacted molar was removed following which the tooth was luxated and laterally transposed. The socket was thoroughly irrigated and closure was done by simple interrupted suture, using 3-0 mersilk. Results: The impacted and inverted maxillary third molar was successfully removed by lateral transposition method without any complications. Conclusion: The impacted and inverted maxillary third molars are not commonly encountered in dental practice. Subsequently, their removal can be a challenging job on the part of an oral surgeon. The surgeon should preoperatively weigh carefully the associated risk factors and explain them thoroughly to the patient. Keywords:Impacted, Inverted, Lateral transposition, Maxillary third molar.

Non-Hodgkin’s lymphoma (NHL) constitutes a diverse group of lymphoid neoplasm that differs in manner of presentation, response to therapy and prognosis. They are less predictable and have a greater prediction to disseminate to extranodal sites. Their incidence has been increased over the last four decades and, head and neck is the second most common region for the extranodal lymphomas after that of gastrointestinal tract. Approximately 2.5% of malignant lymphomas arise in the oral and paraoral region. Generally, the oral manifestations of NHL are secondary to a more widespread involvement throughout the body. The cause of NHL is still unclear. Most of the lymphomas have been shown to be predominant of B-lineage. We present a case of a B-cell lymphoma with nodal and extranodal involvement.
