Submandibular gland megalith eroding the floor of the mouth: a case report.

Sialolithiasis is the most common pathologic condition affecting the salivary glands. However, large sialoliths (megaliths) are considered rare. The submandibular glands are more susceptible to stone formation than are the other salivary glands. We describe the case of a 55-year-old man with an unusually large sialolith that had eroded the floor of the mouth.

Application of PRF in surgical management of periapical lesions.

AIMS AND OBJECTIVES: Platelet rich fibrin is widely used in stimulation and acceleration of soft tissue and bone healing because of local and continuous delivery of growth factors and proteins, mimicking the needs of the physiological wound healing and reparative tissue processes. This article will serve to introduce a second generation platelet concentrate, platelet-rich fibrin (PRF). MATERIALS AND METHODS: Fifteen cases are presented in which conventional endodontic therapy failed to resolve the problem and periapical root-end surgery was required. RESULTS: At the end of six months, all patients showed complete bone regeneration. CONCLUSION: Production of a dense, cross-linked, physically robust PRF made of intact platelets and fibrin by high-speed centrifugation in the absence of exogenous thrombin, yields an ideal scaffold for use in tissue repair.

Single puncture arthrocentesis of temporomandibular joint; introducing a novel device: A pilot study.

INTRODUCTION: Arthrocentesis is a method of irrigating the temporomandibular joint (TMJ) with a therapeutic substance. It is usually performed by dual puncture with two needles to the joint space. Several studies have shown that arthrocentesis of the upper compartment of the TMJ may be a highly effective method to restore normal maximal mouth opening and functioning. Nonetheless, the classical two needle technique has some limitations, such as the low tolerability and difficulty in performing it in the presence of intra-articular adherences. The adoption of a single puncture technique for both fluid injection and aspiration might have some advantages with respect to the traditional two needle approach in terms of time of execution, tolerability, and retention of medication. MATERIALS AND METHODS: A single puncture technique with a self fabricated device is used to assess the efficacy of this device. This study involved 20 patients of age ranging between 20- 64 years diagnosed with TMD. Patients follow up done at 3(rd), 14(th), 45(th) and 90(th) day and assessment of pain, mouth opening, clicking and deviation done with comparison of pre and post-operative data. RESULTS: The procedure was successful in all the patients. Most of the patients reported reduction in pain more than half of the previous value and two patients reported only moderate reduction. There was a clinically significant improvement in mouth opening, clicking and deviation. CONCLUSION: Arthrocentesis is effective in treating TMJ internal derangement and restoring its function. Single puncture arthrocentesis, is a minimally invasive, simple, inexpensive & highly efficient procedure that can be performed under local anaesthesia.

Fractures of angle of mandible - A retrospective study.

AIMS: This retrospective study was done to evaluate the efficacy of single miniplate osteosynthesis at superior border of angle of mandible. MATERIAL AND METHODS: In this study 50 patients were treated by single miniplate osteosynthesis according to Champy's principle. Bite force generated was used as a parameter for judging the efficacy of internal fixation. In this article we present our experience over the years in the management of the fractures of angle of mandible based on this model. RESULTS: Most patients were of 21-30 yrs of age with unilateral angle fracture of mandible except one patient who had isolated bilateral angle fracture. The patients were treated successfully according to Champy's principle of osteosynthesis. There was a progressive improvement in the bite force generated after osteosynthesis. CONCLUSIONS: The angle of the mandible is an anatomically weak and an area susceptible to fracture. The presence of an impacted or partially erupted third molar tooth further weakens it. Angle of mandible is the most common site for fracture however, bilateral angle fracture is very rare and uncommon. Osteosynthesis according to Champy's model led to an early functional improvement as demonstrated by the bite force generated.

Calcifying epithelial odontogenic tumor (Pindborg tumor).

The calcifying epithelial odontogenic tumor (CEOT) is a rare entity and represents less than 1% of all odontogenic tumors. Dr. J J Pindborg (1958) first described four cases of this unusual lesion; subsequently Shafer et al coined the term Pindborg tumor. This lesion is a locally aggressive benign odontogenic neoplasm arising from epithelial tissue. It occurs most commonly in 4(th)-5(th)-6(th) decade of life and bears no gender predilection. A case of CEOT in a 50-year-old male arising in the left body region is described.

Surgical management of masseteric hypertrophy and mandibular retrognathism.

Masseter hypertrophy is a rare condition. It is mostly idiopathic with no known cause. It is recognized as an enlargement of one or both masseter muscles. Most patients complain of facial asymmetry; however, symptoms such as trismus, protrusion, and bruxism may also occur. This article reports a case of bilateral masseter hypertrophy with retrognathic mandible in which comprehensive treatment was rendered to the patient by using a combination approach.

Pleomorphic adenoma of the soft palate.

Pleomorphic adenoma is the commonest benign salivary gland tumour, accounting for almost three fourths of all such tumours. Pleomorphic adenoma most commonly occurs in the parotid gland; however it is also encountered in the submandibular, sublingual and minor salivary glands.Almost half of all salivary gland tumours are malignant, pleomorphic adenoma is the commonest benign lesion.A case of pleomorphic adenoma arising denovo in the minor salivary glands is discussed.

Comparison of octyl-2-cyanoacrylate and conventional sutures in facial skin closure.

INTRODUCTION: Closure of wounds to achieve an esthetically pleasing result has always been a challenge. Since time immemorial, surgeons have strived to produce "invisible scars". This, however, has always been elusive. The introduction of tissue adhesives heralded the era of suture free closures which led to better results. AIMS AND OBJECTIVES: The aim of this study is to compare the efficacy of octyl- 2-cyanoacrylate with that of the conventional sutures, in facial skin closure. RESULTS AND CONCLUSION: The use of octyl-2-cyanoacrylate offers many advantages such as rapidity and ease of application and superior results.

Analysis of cephalometrics for orthognathic surgery: Determination of norms applicable to Rajasthani population.

AIMS: To determine the hard tissue surgical cephalometric norms statistically and geometrically in well-balanced faces having clinically acceptable facial profile in the Rajasthan population. To compare the cephalometric analyses of Rajasthanis males and females and to compare the craniofacial pattern of Rajasthani population with Caucasian norms. MATERIALS AND METHODS: Lateral cephalograms of 200 subjects (100 males and 100 females) in the age group of 18-25 years, class I malocclusion and acceptable facial profile were obtained. Cephalometric analysis was performed and studied. RESULTS: The study revealed that parameters, such as all horizontal skeletal parameters, PNS-N, PNS-ANS, Ar-Go, Go-Pg and upper OP to HP angle show no statistical significant difference between Rajasthani males and females. When comparing Rajasthani males and Caucasian males, the study suggested statistically significant difference in the mean values of parameters, such as PTM-N, L1-MP, 6-MP, Go-Pog, B-Pog, Ar-Go-Gn, U1 to NF and L1 to MP. When comparing Rajasthani females and Caucasian females, the study revealed no statistically significant difference between the mean values of parameters, such as N-A-Pg, N-A, N-B, L1-MP, Ar-Go-Gn, upper OP to HP angle and AB-OP and rest of the parameters showed highly significant difference between Caucasian females and Rajasthani females. CONCLUSION: This study indicates that Rajasthani population has a bimaxillary protrusion with predominant tendency toward horizontal growth pattern of the mandible and this tendency is further exaggerated in females. Rajasthani females also showed an increased length of the anterior cranial base, maxilla and mandible and in dental parameters they showed increased maxillary dental height and both Males and females showed decreased mandibular dental height.
