Different postdesigns and materials are available; however, no consensus exists regarding superiority for stress distribution. The aim of this study was to evaluate the effect of design and material of post with or without ferrule on stress distribution using finite element analysis.A total of 12 three-dimensional (3D) axisymmetric models of postretained central incisors were made: Six with ferrule design and six without it. Three of these six models had tapered posts, and three had parallel posts. The materials tested were titanium post with a composite resin core, nickel chromium cast post and core, and fiber reinforced composite (FRC) post with a composite resin core. The stress analysis was done using ANSYS software. The load of 100 N at an angle of 45 was applied 2 mm cervical to incisal edge on the palatal surface and results were analyzed using 3D von Mises criteria.The highest amount of stress was in the cervical region. Overall, the stress in the tapered postsystem was more than the parallel one. FRC post and composite resin core recorded minimal stresses within the post but the stresses transmitted to cervical dentin were more as compared to other systems. Minimal stresses in cervical dentine were observed where the remaining coronal dentin was strengthen by ferrule.A rigid material with high modulus of elasticity for post and core system creates most uniform stress distribution pattern. Ferrule provides uniform distribution of stresses and decreases the cervical stresses.

We report a case of calcifying epithelial odontogenic tumour (CEOT), also known as a Pindborg tumour, with local aggressive behaviour. CT imaging showed a large expansile bone-forming lesion in the mandible, which showed the exact extent and nature of the lesion. We briefly discuss the imaging features of CEOT and the relevant literature. © 2012 The British Institute of Radiology.

Congenital erythropoietic porphyria (CEP) is one of the rarest of porphyrias occurring worldwide. CEP is a very rare genetic autosomal recessive disease, with mutation in the gene that codifies uroporphyrinogen-III synthase, leading to porphyrin accumulation in many tissues, with marked skin photosensitivity, hemolytic anemia with splenomegaly and a decreased life expectancy. We report a case of Günther's disease in view of its rarity along with a description of this interesting condition. An 18-month-old female baby with clinical, hematological and biochemical profile of CEP was reported with marked skin photosensitivity over face and hands. She had erythrodontia with delayed eruption of teeth. When evaluating erythrodontia of uncertain cause, we advocate maintaining a high degree of awareness for porphyria, especially for CEP as it is the rarest among porphyria and is a life-threatening condition.

Complex odontomas are less frequently found as compared to the compound odontomas and they are considered to be hamartomatous malformations rather than true neoplasms. They are generally asymptomatic and are frequently found during a routine radiological examination. Occasionally, they become infected and cause pain and swelling. Here, we report a case of infected complex odontoma and the importance of CT in terms of its diagnosis and treatment planning.

Myositis ossificans is a rare disease that is characterized by bone deposition in the muscle or soft tissues. Myositis ossificans of the masticatory muscles is an uncommon finding. The condition is benign and results in heterotopic bone formation in the muscles of mastication, usually producing limitation of opening of the jaws. It is important to know the exact cause of the limitation of opening of the jaws for successful treatment. Computed tomographic scan and panoramic radiographs along with histological findings are essential diagnostic aids for evaluating conditions such as myositis ossificans. A rare case of myositis ossificans traumatica of temporalis and medial pterygoid muscle is presented here along with the discussion of clinical, radiological and histological features. The present case emphasizes not only on the importance of considering myositis ossificans in the differential diagnosis of limitation of opening of the jaws but also on the improvement of the overall mouth opening and treatment results.

Background: Myofascial pain dysfunction syndrome (MPDS), otherwise called myofascial pain is one of the most common temporomandibular disorders, which in turn is the most common cause of orofacial pain of non-dental origin. Its etiology is multifactorial and still poorly understood. Psychological factors have been shown to play a role in the etiology. The aim of the study was to evaluate the association between anxiety and salivary cortisol levels in patients with myofascial pain. Methods: Twenty patients suffering from myofascial pain were recruited as the study group. The same number of age and sex matched healthy individuals were taken as the control group. The salivary samples collected between 9-9:15 am from both groups were analyzed for cortisol levels with the competitive enzyme-linked immunosorbent assay method. Anxiety levels of 40 patients were measured using Hamilton's anxiety scale. Results: The mean serum cortisol level of the MPDS group showed a highly significant difference (P < 0.001) from the controls. The mean anxiety scores of the MPDS group showed a highly significant difference (P < 0.001) from the controls. A positive correlation was found between anxiety and the salivary cortisol levels in MPDS patients. Conclusions: These findings suggest that anxiety plays a vital role in the etio-pathogenesis of MPDS; thus, besides pharmacological treatment, psychological support is also needed. © The Korean Pain Society, 2014.

Child abuse and neglect are important public health problems and recent estimates of their prevalence suggest that they are considerably more common than had hitherto been realized. Intervening to change parenting practices may, however, be important in their treatment. Despite their frequent occurrence among dental patients, neglect is the least known and identified type of abuse. The present case reports a 3-year-old girl suffering from abuse and neglect. The girl had dental neglect and also performed poorly in all parameters of growth and development. This case describes the process that was followed in order to reach a diagnosis and safeguard the child. The parent was counseled and the girl got her due share of access to comprehensive oral and general health. This case emphasizes that the dental professional should always be vigilant and collaborates among like-minded individuals to increase the prevention, detection and treatment of these conditions.

Osteosarcoma is a non-hematopoietic primary malignant tumor of bone or mesenchymal tissue. Although osteosarcoma is not a common malignant bone tumor, accounting for approximately 20% of sarcomas, tumor of the jaw bone is uncommon, representing only about 4% of osteosarcomas of long bones. We report a case of a 72-year-old female with a swelling on the left side of the mandible and intra-oral swelling on the floor of the mouth. Conventional radiograph and advanced imaging modalities such as computed tomography and magnetic resonance imaging revealed an intramedullary osteosarcoma of the mandible. This report highlights importance of imaging modalities in the diagnosis of malignant tumors of the jaws. © 2014 Chittaranjan B.

In addition to malignant cells, solid tumours comprise supporting stromal tissue that consists of Extra Cellular Matrix (ECM), connective tissue cells, inflammatory cells and blood vessels. The stromal compartment and the malignant cells together shape the tumour microenvironment that in turn determines tumour progression and efficacy of anti-tumour treatments. It is now recognized that the host microenvironment undergoes extensive change during the evolution and progression of cancer. This involves the generation of Tumour-Associated Fibroblasts (TAFs), which, through release of growth factors and cytokines, lead to enhanced angiogenesis, increased tumour growth and invasion. It has also been demonstrated that TAFs may modulate the Cancer Stem Cell (CSC) phenotype, which has therapeutic implications. Understanding the various components in the tumour microenvironment may afford us the opportunity to develop new drugs that target these reversible nonmutational events in the prevention and treatment of cancer.

Non-Hodgkin's lymphomas are a group of highly diverse malignancies and have a strong tendency to affect organs and tissues that do not ordinarily contain lymphoid cells. Primary extra nodal lymphoma of the hard palate is rare. Here, we present a case of diffuse large B cell lymphoma in a 60-year-old male patient that manifested as slightly painful ulcerated growth on the edentulous right maxillary alveolar ridge extending onto the palate, closely resembling carcinoma of the alveolar ridge. Computed tomography images showed the involvement of the maxillary sinus and right nasal cavity, along with destruction of hard palate, superiorly extending into the orbit. This case report highlights the importance of imaging to evaluate the exact extent of such large malignant lesions, which is essential for treatment planning. © 2012 by Korean Academy of Oral and Maxillofacial Radiology.
