Forensic odontology or forensic dentistry has generated so much interest in the recent past that it has been suggested an important method in solving forensic cases in mass disaster, child abuse, bite mark analysis, crime/natural death, injuries and bio-terrorism. Commonly used methods in forensic odontology include Rugoscopy, Chieloscopy, Bite marks, Tooth prints (Ameloglyphics), Radiographs, Photographic study and Molecular method. However there are certain pitfalls associated with the above methods in forensic odontology, which are to be weighed cautiously to make forensic odontology a more accurate, reliable and reproducible investigatory science. In this paper we present our understanding of the limitations/ boundaries in various method employed in forensic odontology

Several factors influence the rate of decalcification, and there are ways to speed up or slow down this process. The concentration and volume of the active reagent, including the temperature at which the reaction takes place, are important at all times. Other factors that contribute to how fast bone decalcifies are the age of patient, type of bone, size of specimen, and solution agitation. Mature cortical bone decalcifies slower than immature, developing cortical or trabeculae bone. Of all the factors, the effectiveness of agitation is still being debated.1,2

The correction of deep bite is one of the primary objectives of orthodontic treatment and optimal treatment of deep bite requires a proper diagnosis, a careful treatment plan and an efficient appliance design. An unfavorable sequelae of this malocclusion predisposes a patient to periodontal involvement, abnormal function, improper mastication, excessive stresses, trauma, functional problems, bruxism, clenching and temporomandibular joint disturbance that make geriatric dental service a losing battle unless overbite can be controlled.

An aesthetic and comfortable maxillofacial prosthesis can make huge differences for the patients with Maxillofacial defects due to cancer, trauma or congenital diseases .Maxillofacial defects are located in highly visible body area that is identified with one’s own identity ,so accurate representation of skin color in facial prosthesis is essential for achieving successful aesthetic results It remains one of the subsequent pigmentation but they are important issues during prosthesis fabrication process .The ability to match skin tones effectively requires keen eye ,good understanding of color theory & meticulous attention to details.(1) Materials used in the fabrication of these facial prostheses can be silicones that are tinted externally and internally to match the colour of the surrounding facial structures.(2)

Introduction: Orthodontic treatment planned to correct sagittal or transverse discrepancy must always consider movement in vertical plane as well. Hence, the purpose of this study was to evaluate changes in vertical planein adult Orthodontic patients who had undergone fixed Orthodontic treatment with the extraction of first premolars. Materials and Method:The pre and post treatment lateral cephalogram of fifteenpatients weretaken and traced, and several cephalometric variables (hard and soft) were measured to evaluate the vertical changes.Data was analyzed statistically. Result: Significant difference in parameters likeInterincisal angle, linear distance of incisor and molar to palatal plane, Interlabial gap and Maxillary incisor exposure whereas non-significant difference was seen in the other parameters like Mandibular plane angle, Y- axis, Gonial angle, Anterior lower facial height, Maxillary and Mandibular height etc. Conclusion:The changes in vertical parameters like facial height and clockwise rotation of mandibular plane was not seen in the present study. The appropriate measures that are incorporated in our biomechanics as per the case to minimize changes in vertical dimension must be followed strictly.

The ideal restoration of endodontically treated teeth (ETT) has been widely and controversially discussed in the literature. Prevention of healthy dental structure is essential to help mechanical stabilization of tooth-restoration integrity, increase the amount of suitable surfaces for adhesion and thus positively affect the long-term success. ETT are affected by a higher risk of biomechanical failure than vital teeth. With the development of adhesive systems, the need for post-core restorations is also reduced. Especially for restoration of excessively damaged ETT, endocrowns have been used as an alternative to the conventional post-core and fixed partial dentures. Compared to conventional methods, good aesthetics, better mechanical performance, and less cost and clinic time are the advantages of endocrowns.

The evolutionary cycle has selected a masticatory system, which is functionally efficient using natural teeth and an omnivorous diet. This system would be designed in a totally different fashion if it were selected based on the model of the complete denture wearer.1Dentures are rigid pieces of acrylic resin which are shaped to fit the soft tissue covering of the jaws and be compatible with the functioning and ever changing oral environment. Dentures are subject to the physical laws which form the realities of this oral environment. No denture, regardless of how well it is constructed, can overcome the limitations of the foundation on which it is placed.2In day-to-day practice we encounter many patients for whom an ideal treatment from prosthodontics point of view is not possible without resorting to pre-conditioning of the oral tissues by means of surgical procedures. These procedures constitute the pre-prosthetic surgical preparation.2A considerable number of complete denture patients endure continuous discomfort with their dentures and seek help from one prosthodontist after another. They in turn construct and reconstruct new dentures at considerable expense of time and money until finally the patient gives up and has recourse to cotton wool inserts or proprietary relining materials convinced by the advice that they are 'dental cripples' and beyond professional help.3The more major pre-prosthetic operations are not easy to perform and require repetitive experience and surgical skill which is not easy to achieve doing the 'odd' case. It is also essential for the prosthodontist to understand the needs of the complete denture patients and also to understand the aims of surgery and its difficulties.3
