Dental evidence has been proved to be the most useful single method of confirming identity, especially in mass disasters, but its usefulness is being compromised by inaccuracies in charting. These may be no more than an inconvenience, but they may make identification difficult. This paper describes three cases in which errors in charting caused some difficulty during forensic examinations of bodies, and delayed the identification of these victims.

Introduction: Dental evidence is valuable in identification of individuals, especially following mass disasters; estimation of age at death of skeletonised remains and establishing guilt in cases of criminal injury by biting. Mandibular canines are found to exhibit the greatest sexual dimorphism amongst all teeth. Objective: To investigate the accuracy with which gender can be differentiated by using the mandibular canine index in the Punjabi – Pakistani population. Setting: Independent Medical College and Punjab Medical College,  aisalabad. Period: Dec. 2008 to Dec. 2009. Material and Methods: The present study was performed on 200 students, between the age group of 18-25 years, randomly sampled with informed consent (Through 3rd party). Mandibular canine width and intercanine distance were measured with the help of Vernier caliper after observing aseptic conditions. Mandibular canine index was calculated and the observed MCI was compared with the standard MCI value. The data was then analyzed using student’s “t” test. Results: No significant statistical difference was noted between the right and left mandibular canines amongst males and females (same sex) but when comparing between males and females, there was highly statistical significant difference (P < 0.001). The calculated standard MCI for canines of males and females found to be 0.2504. With these calculations we could predict sex correctly at 75.97% in this study (Male: 71.67% and Female: 78.72%). Conclusion: MCI is a quick and reliable method for sexual identification when a standard for the population is available. With these calculations, we could predict the sex correctly at 75.97 % in this study. This method can be used as adjunct to other available tools for sex determination. DNA studies can reveal sex accurately.Availability of comprehensive database with “NADRA” can also be used as adjunct to “MCI” to enhance the accuracy in determination of sex and identity of the person in Pakistan.

Abstract: Forensic dentistry is the field which is a combination of forensic and dentistry. In this we go for principles used in dentistry or dentistry forthe use in judiciary. It is one field inwhich we collectthe evidence related to dentistry and analyze them for the purpose of investigation. In a crime scene or a disaster situation a lot of destruction occurs. It becomes important to determine the identity of an individual and we can say it is the identity of the deceased. This study is being conducted based on previous research and literature presented by various research scholars. When it comes to a crime scene where we do not get the victim or culprit but we find the dentalevidence and also in cases of mass disasters, catastrophic events, industrial disasters where identification is necessary if we found the dental evidence, they can help a lot in determining age, gender partial identity can be known through this evidence. Many methods are there to determine identity through dental evidence and also apart from dental evidence we have orthometric methods but dental evidence is found to be more cheap, easy, fast methods. In this we have discussed how DNA is extracted from the teeth and it's further processing so that it will help in establishing someone's identity.

Abstract Introduction Dental evidence is valuable in identification of individuals, especially following mass disasters. Canines are found to exhibit the greatest sexual dimorphism amongst all teeth. Objective To investigate the accuracy with which gender can be differentiated by using the maxillary and mandibular canine indices in an Indian population. Material and Methods The present study was performed on 200 subjects (100 males, 100females) between the age group of 18-25 years, randomly sampled with informed consent (Through 3rd party). Results Males showed greater mean mesiodistal dimensions for each tooth in comparison to females in both maxillary and mandibular arches. When the level of accuracy for sex determination was measured using maxillary canine index it was found that 55% females and 60% males were classified correctly. The level of accuracy for sex determination using mandibular canine index found 67% females and 78% males were classified correctly. Conclusion canine indices are a quick and reliable method for sexual identification when a standard for the population is available. With these calculations, we could predict the sex correctly at 72.5% and 57.5 % in this study for mandibular and maxillary canine indices respectively. This method can be used as adjunct to other available tools for sex How to cite this article Pramod RC, Nupura V, Suresh KV, Vidya K, Sharan JS, Neha S.

ABSTRACT This communication is an attempt to delineate and define reliability criteria for saturation analysis of steroids by competitive protein binding assay. The discussion of these criteria evolved from three major considerations of assay method that help to place the ultimate criterion of accuracy in proper perspective. These major considerations are: 1) the measurement system, 2) the assay design and 3) the calculations and statistical control. Such an approach permits an evaluation, both relative and absolute, for a single method or for multiple methods.

Aromatic chloroformates Ib-Ie were shown to exist in the ap conformation, in agreement with aliphatic chloroformates, i.e. the alkyl group is situated cis to the carbonyl oxygen atom as it is the case in all esters. While 4-nitrophenyl chloroformate (Ie) is in this conformation in crystal, in solution at most several tenths of percent of the sp conformation may be populated at room temperature and in nonpolar solvents only. A new analysis of dipole moments explained the previous puzzling results and demonstrated the impossibility to determine the conformation by this single method, in consequence of the strong interaction of adjoining bonds. If, however, the ap conformation is once proven, the dipole moments reveal some features of the electron distribution on the functional group, characterized by the enhanced polarity of the C-Cl bond and reduced polarity of the C=O bond. This is in agreement with the observed bond lengths and angles.

ABSTRACT Background Quality Indicator (QI) appraisal protocols are a novel methodology that combines multiple appraisal methods to comprehensively assess the "appropriateness" of QIs for a particular healthcare setting. However, they remain inadequately explored compared to the single appraisal method approach. This paper aimed to describe and test a QI appraisal protocol versus the single method approach, against a series of QIs potentially relevant to the South African Prehospital Emergency Care setting. Methods An appraisal protocol was developed consisting of two categorical-based appraisal methods, combined with the qualitative analysis of the discussion generated during the consensus application of each method. The output of the protocol was assessed and compared with the application and output of each method. Inter-rater reliability of each particular method was evaluated prior to group consensus rating. Variation in the number of non-valid QIs and the proportion of non-valid QIs identified between each method and the protocol were compared and assessed. Results There was mixed IRR of the individual methods. There was similarly low to moderate correlation of the results obtained between the particular methods (Spearman’s rank correlation=0.42,p&lt;0.001). From a series of 104 QIs, 11 non-valid QIs were identified that were shared between the individual methods. A further 19 non-valid QIs were identified and not shared by each method, highlighting the benefits of a multi-method approach. The outcomes were additionally evident in the group discussion analysis, which in and of itself added further input that would not have otherwise been captured by the individual methods alone. Conclusion The utilization of a multi-method appraisal protocol offers multiple benefits, when compared to the single appraisal approach, and can provide the confidence that the outcomes of the appraisal will ensure a strong foundation on which the QI framework can be successfully implemented.

The following review aims to examine the available evidence to guide best practice in preventing ovarian hyperstimulation syndrome (OHSS). As it stands, there is no single method to completely prevent OHSS. There seems to be a benefit, however, in categorizing women based on their risk of OHSS and individualizing treatments to curtail their chances of developing the syndrome. At present, both Anti-Müllerian Hormone and the antral follicle count seem to be promising in this regard. Both available and upcoming therapies are also reviewed to give a broad perspective to clinicians with regard to management options. At present, we recommend the use of a “step-up” regimen for ovulation induction, adjunct metformin utilization, utilizing a GnRH agonist as an ovulation trigger, and cabergoline usage. A summary of recommendations is also made available for ease of clinical application. In addition, areas for potential research are also identified where relevant.
