Sexual Dimorphism in Human Mandibular Canine Teeth: A Radiomorphometric Study

Objectives: The objective of this study was to determine whether the variation in the mesiodistal measurement of mandibular canine played a role in sex determination. Materials and methods: The study comprised of patients in the age group of 19 to 24 years (20 males and 20 females). Mesiodistal measurement of mandibular canines was measured at the maximum mesiodistal width first intraorally, then on plaster models of the same patient followed by intraoral periapical radiograph of the same patient. Results: From the findings of the study, it may be inferred that there exists a definite statistically significant difference in the mesiodistal width of mandibular canines when measured for males and females. Moreover, the left mandibular canine showed a greater sexual dimorphism (9.7%) when compared to the right mandibular canine (7.4%) Conclusion: The present study establishes a statistically significant sexual dimorphism in mandibular canines- It can be concluded that the standard mandibular canine index is a quick and easy method for sex determination

Carbonation of Phenol: A Novel Reaction Involving Enzyme Model Catalysis

In the presence of an anion exchange resin, IR 45, indazolone and other structurally related compounds are observed to catalyse ortho carbonation of phenol in water under ambient conditions to produce salicylic acid alongwith, an unexpected product, benzoic acid

Traumatic Sialocele of Parotid Duct: Report of a Case with Review of Literature

Parotid gland or duct injury can be caused by assault with a knife, bottle, or more rarely gunshot. Post-traumatic parotid gland and duct injuries are not common. The low rate of occurence of parotid injury may account for the missed diagnosis of parotid and duct injury on admission and, after a varying period sialoceles or fistula. This report describes a case of a post-traumatic sialocele of parotid gland. A review of the literature and description of the medical and surgical management options for these injuries are also provided
