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.

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.

Dental Evidence

Dental evidence has been demonstrated as a major forensic tool for the identification of individuals and sex determination. The objective of the research was to determine sex in Delta Ibo ethnic group of Nigeria using the mandibular and maxillary canine teeth. Materials and methods. The study comprised 201 (100 males and 101 females) subjects of Delta Ibo ethnicity at the age of 17 – 25 years. The mesiodistal crown width and intercanine distance of both the maxillary and mandibular canines were measured intraorally using a pair of dividers and a ruler. Unpaired T-test at a probability value of p<0.05 was used to ascertain the mean significant differences between the male and female canine indices.   Results. Study results showed a statistically significant difference between male and female mandibular and maxillary canine mesiodistal width. This implied a sexual and reversed sexual dimorphism in the studied population.        Conclusions. The study confirmed that the canines of Delta Ibos exhibit sexual dimorphism like other populations and the maxillary canine indices give the most accurate prediction in sex determination.

Introduction: Forensic odontology is a unique discipline dealing with evidence related to dental and oral structures. Mandibular canines are considered to be an important aid for sex determination. The aim of this study was to analyse the role of mandibular canine index in sex determination of Mumbai city population. Materials and Methodology: This was a retrospective study done on the study models of 50 patients aged between 17 to 25 years old and equally distributed among both the sexes, whose treatment has been taken place in The Department of Orthodontics, Nair Hospital Dental College, Mumbai. Mesio-distal width of mandibular canines were measured using a digital Vernier calliper and mandibular canine index was calculated using standardized equation. Independent sample t-test was used and P < 0.05 was considered statistically significant. Results: There was a significant difference (P < 0.05) observed between right and left mandibular canine width and a significant difference between the right and left mandibular canine index between males and females. Conclusion: The present study verifies the fact that mandibular canine index can be used for sex determination in the population of Mumbai city and can form basis for forensic investigations.

Knowledge of sex of a person becomes the first priority of a forensic investigator in the process of identification. Dental evidence pours in an invaluable informative data towards achieving the final positive results in establishing the unknown’s identity. Studies have shown that the mandibular canine resist disease, survive extreme post-mortem environmental conditions and presents the highest sexual dimorphism amongst all teeth, making them an ideal teeth in forensic identification procedures. The aim of present study was to know the use of the Mandibular Canine Index (MCI) in assessing sex in North Indian population. In a sample size of 80 males and females (40 male and 40 female) in the age group 21-24years, mandibular canine width and Inter canine distance measurements were noted intraorally and the MCI was calculated and compared with stranded MCI values.

Hitherto, there is no proper line of treatment for the new (nCOVID19). The development of unique antiviral drugs has taken precedence. Therapeutic antibodies () will be a significantly beneficial agent against nCOVID-19. Here the host immune responses to new discussed in this review provide strategy and further treatment and understanding of clinical interventions against nCOVID-19. Plasma therapy uses the antibodies found in the blood of people recovering (or convalesced) from an infection to treat infected patients. When an infection occurs, the body begins producing proteins specially made to kill the germ, called antibodies. Those antibodies coat specifically plasma in the blood of survivors, the yellow transparent liquid blood portion for months or even years. research assesses plasma use from Convalescent patients of infected with nCOVID-19 as a possible preventive treatment. But it is not yet recommended as a line of treatment, and it is used as a clinical trial in the new in Indian population.
