ABSTRACT
Studying malocclusion during active growth period is important because this period has the maximum impact on dentofacial structures. The present study comprises of computerised cephalometric evaluation of 100 North Indian children in the age group of 9-12 years, with 50 children in normal occlusion group. The samples were segregated according to sex with 25 females and 25 males in each group. It was concluded from the study that changes or deviations in SNB, Saddle, Articular and Gonial angles are the potential indicative factors in the development of a class II malocclusion and that class II pattern is associated with short and posteriorly placed mandible in relation to the cranial base.

Reattachment of the original tooth fragment to the fractured tooth provides benefits of maintaining the tooth's shape, colour texture and translucency in the restoration. This paper describes fragment reattachment of a non-vital central incisor five months after trauma.

Iodoformized zinc oxide-eugenol was tested for its antibacterial effect against the aerobic and anaerobic bacteria obtained from the root canals of deciduous teeth; the bacteria were staph aureus, strep viridans, strep faecalis, bacteroides melaninogenicus and also mixed culture obtained from infected non-vital anterior teeth. The sensitivity was checked on BHI- agar plates employing well-method. Iodoformized zinc oxide eugenol paste was found to be effective for both the aerobic and anaerobic bacteria of the root canals of deciduous teeth with maximum sustaining period of 10 days; staphylococcus aureus was found to be the most susceptible, while Streptococcus faecalis the most resistant.
