One in two children had dental caries. Oral hygiene practices were associated with dental caries. Certain inequalities in oral health were observed.

In the study reported, the efficacy of polymerization for two curing units was determined by examining the degree of conversion for different composite materials. The degree of conversion values varied according to the type of resin (nanofilled-macrofilled-hybrid-microhybridormocer), brand and light polymerizing unit.

This study evaluated the importance of microRNA in classical mixed cellularity Hodgkin lymphoma (MCHL) pathogenesis. We thought that microRNAs may play an important role in the biology of paediatric MCHL and may be useful in developing therapies targeting microRNAs.
