ABSTRACT : INTRODUCTION : MATERIAL AND METHODS: Aim: To evaluate the effect of different enamel preparations on fracture resistance of composite resin buildup of fractures involving dentin in anterior teeth. Material and Methods: Forty sound extracted human permanent incisors were selected. Samples were randomly and equally divided in one untreated (control) group and three experimental groups (Bevel, Chamfer and newly introduced Stair-step Chamfer preparation group) to evaluate the effect of enamel preparations on the fracture resistance of composite resin. According to the group, the teeth were prepared and restored with corresponding designs of enamel preparations with similar composite resin. The teeth were subjected to compression bending test under Instron Testing Machine. The observational values obtained were subjected to statistical analysis. Results: Significant difference was found between all groups preparations except between chamfer & stair step-chamfer (p> 0.05).Conclusions: The highest fracture resistance was about 50% of intact teeth. Composite restorations showed maximum resistance to fracture when chamfer preparation was used.

ABSTRACT:

Aim: The present study was undertaken to evaluate the reliability of sagittal parameters utilizing FABA, AB plane angle, ANB angle, AF BF and Wits appraisal from randomly selected subjects. Thirty pre treatment lateral cephalometric radiographs of 10-25 years old individuals were randomly selected from the orthodontic record files of Department of Orthodontics and Dentofacial Orthopedics, Surendera Dental College and Research Institute, Sri Ganganagar, Rajasthan. Minimum and maximum value, range, mean and standard deviation were calculated for each subject. Mean and standard deviation of each parameter was done by one way analysis of variance (ANOVA).Coefficients of Variability of all parameters was calculated. A correlation coefficient analysis (Pearson’s coefficient of correlation) was done to assess the significance of association between the variables. The reproducibility was calculated by paired measurement comparisons with t-test. The level of statistical significance was set at p≥ 0.05. The measurement with the most homogenous distribution was FABA angle (c.v7.83), followed by AB plane angle (c.v- 53.81), AF-BF (c.v53.87), ANB angle (c.v- 64.25) and the least homogenous was the Wits occlusal plane (c.v- 122.76). Despite varying strengths of association all the parameters used in the study shared statistically significant correlation amongst themselves. The results of the present study showed perfect positive correlation between angle ANB and AF-BF(r=0.826) and perfect negative correlation between angle ANB and A-B plane angle(r=-0.817) and angle FABA and AF-BF (r=-8.69). Clinical implications of the study showed that FABA angle, AB plane angle and AF-BF were statistically significant to assess the sagittal jaw relationship between maxilla and mandible and may be used to predict the skeletal class in addition to the established ANB angle. Instead of relying on one single parameter, others also should be checked and should be correlated with clinical findings. No single parameter or one approach can be used to give an accurate picture for the jaw relationship.

Abstract
In recent years there is a phenomenal upsurge of knowledge and research on disaster management across wide range of disciplines and subjects. Natural or manmade catastrophic events place great manpower demands on communities and their health care and public health systems. This calls for ever preparedness on the part of the health care workers. Dentists are not perceived as much of help in case of any disaster event. Although the first responders are primarily looked upon for in case of any disaster response; if called upon dentists can be a source of vital support in medical surge events. Dentists and dental auxiliaries can augment the existing medical professionals, in responding to a declared medical emergency. Dentists are exposed to information in many general medical areas during their pre-doctoral education that can be useful in disaster response situations. Dentists have the clinical skills and medical knowledge that are invaluable assets in a mass casualty event. Dentists can be given the opportunity with additional targeted training to become more effective responders to natural disasters and other catastrophic events. Inculcating disaster training in the undergraduate and post graduate curriculum will better prepare the dentist for any surge event. The present article explores the various duties which dental professionals can play in a major public health disaster.

Abstract
Herbs are one of remedial agents which God has created for afflicted humans. Herbal extracts have been used in traditional medicine since the human existence. A herb, botanically speaking, is any plant that lacks the woody tissue which is characteristic of shrubs or trees. More specifically, herbs are plants which are used medicinally or for their flavour or scent. Herbs with medicinal properties are a useful and an effective source of treatment for various disease processes. Herbal extracts have been successfully used in dentistry as tooth cleaning and antimicrobial plaque agents. The use of herbal medicines continues to expand rapidly across the world. Many people take herbal medicines or herbal products now for their health care in different national healthcare programmes. Herbal extracts have been used in dentistry for reducing inflammation, as antimicrobial plaque agents, for preventing release of histamine and as antiseptics, antioxidants, antimicrobials, antifungals, antibacterials, antivirals and analgesics. They also aid in healing and are effective in controlling microbial plaque in gingivitis and periodontitis, thereby improving immunity, oral & general health as well.

Abstract: Fibrous dysplasia is a developmental benign bone lesion characterized by the replacement of normal bone by excessive proliferation of cellular fibrous connective tissue which is slowly replaced by bone, osteoid or cementum like material. It causes bone pain, deformities and pathological fractures. It may either be monostotic or polyostotic. It has now become evident that fibrous dysplasia is a genetic disease caused by somatic activating mutation of the Gs subunit of G protein-coupled receptor resulting in up regulation of cAMP. This leads to defects in differentiation of osteoblast with subsequent production of abnormal bone in an abundant fibrous stroma. Fibrous dysplasia can affect any bone in the body. The most common sites are the bones in the skull and face, femur, tibia, humerus, pelvis, and ribs. The disease may occur alone, or as part of a condition known as the McCune- Albright syndrome. which is characterized by fibrous dysplasia and other symptoms such as patches of pigmented skin and endocrine problems such as early puberty , hyperthyroidism , excess growth hormone), excess cortisol etc.

Abstract : Bio-mimetic Dentistry the art and science of restoring damaged teeth with restorations that mimic natural teeth in appearance, function, and strength. Bio-mimetic means what is life-like. Nature has given our natural tooth ,the most ideal properties. Bio-mimetic dentistry return the tooth to its original form and function in strong and conservative way. BIO mean-life like , MIMETIC mean copy . The goal of biomimetic in restorative dentistry is to return all the prepared dental tissues to full function by the creation of a hard-tissue bond that allows functional stresses to pass through the tooth, drawing the entire crown into the final functional biologic and esthetic result. Bio-mimetic materials may help bio-mimetic dentistry in achieving its goals.

Abstract: Mandibular dislocation is an acute painful condition that causes severe functional limitation. Manual reduction, with or without pharmacological assistance, is the treatment of choice and should be performed as early as possible. In rare situations mandibular dislocation may not be perceived by the patient and remain undiagnosed or misdiagnosed for a long period and may include severe illness, neurological diseases and prolonged intensive care hospitalization with oral intubation and sedation. Morphological changes of the joint and associated structures will prevent successful manual reduction even with the patient under general anesthesia. Many types of surgeries have been used for the management of chronic recurrent dislocations like condylectomy and condylotomy, eminectomy, kostecka’s osteotomy, sub-condylar osteotomy with coronoidectomy, coronoidectomy, mandibular ramus L-inverted osteotomy, modified sub sigmoid vertical osteotomy, temporal myotomy, fink’s method, traction with wires of the mandibular angle (surgical approach), meniscectomy. A successful management of a case report of a patient with chronic recurrent bilateral dislocation of the mandible by bilateral eminectomies is presented here.

Abstract:  Gingival hyperpigmentation due to melanin deposition is seen as genetic trait in most of the population irrespective of age and gender, hence termed as physiologic or racial gingival pigmentation. Personality of an individual is not only influenced by the outlook but also by the smile he/she carries. As smile expressesa feeling of pleasure, sensuality, care and confidence. The harmony of smile is not only determined by color, position and shape of teeth, but also by color of gingiva. Number of techniques was advised in the literature to obtained pleasing gingival color. In the present case report gingival de-pigmentation was carried out utilizing surgical stripping and electrocautery. Pre and post operative clinical and histopathological evaluation was carried out upto 6 months. Report of the case dictated that both the techniques are simple, effective and provided satisfactory outcomes at 6 months post-operatively but surgical stripping technique dictates to be simple and highly effective in all terms except bleeding and required periodontal dressing postoperatively.

Abstract: Eagle’s syndrome is a disease caused by an elongated styloid process or calcified stylohyoid ligament. Eagle defined the disorder in 1937 by describing clinical findings related to an elongated styloid process, which is one of the numerous causes of pain in the craniofacial and cervical region.. Eagle’s syndrome is usually characterized by neck, throat, or ear pain; pharyngeal foreign body sensation; dysphagia; pain upon head movement; and headache. Patients with increased symptom severity require surgical excision of the styloid process. Here, we report an atypical presentation of Eagles syndrome due to chronic sialadenitis of submandibular gland

Abstract: Severe alveolar ridge resorption is a complicating factor in the construction of complete dentures that determines both stability and retention of the dentures. The Neutral Zone technique is an alternative approach in constructing stable complete denture in case of a highly atrophic mandible.The neutral zone is the area where the displacing forces of thelips, cheeks and tongue are in balance. The Neutral Zone technique aim is to construct denture in harmony with surrounding oral muscles, so that the denture does not get displaced during their activity.The clinical case report presented here describes the successful insertion complete denture utilizing neutral zone technique in a severely resorbed mandibular alveolar ridge.

Abstract: The frenum is a mucous membrane fold that attaches the lip and the cheek to the alveolar mucosa, the gingiva, and the underlying periosteum. The frena may jeopardize the gingival health when they are attached too closely to the gingival margin, either due to interference in the plaque control or due to a muscle pull. In addition to this, the maxillary frenum may present aesthetic problems or compromise the orthodontic result in the midline diastema cases, thus causing a recurrence after the treatment. This case report demonstrates the removal of the abnormal labial frenum attachment in a 38 year old female through the technique of Z-plasty.

Abstract: Pulpless teeth have proved to be very useful members of the dental arch. However, because an enodontically treated tooth is brittle and subject to fracture, it requires reinforcement of a special nature in order to function effectively. It becomes the prosthodontist’s concern to restore the crown and reinstate the tooth as permanent, functional and esthetic member of the masticatory apparatus. This article describes the prosthodontic management of an endodontically treated tooth having very less coronal structure with Richmond Crown.
