Antimicrobial solutions used for root canal disinfection

This article discusses the significance of root canal disinfectants and comments on how these can be used professionally. The complex root canal system is inhabited with different microbes in periapical periodontitis. There is no particular disinfectant that alone satisfactorily fulfills the entire functions essential for irrigation. Best possible irrigation is found on the combined use of two or more disinfectant, in a particular sequence. Sodium hypochlorite is the most commonly recommended endodontic irrigant, in spite of some adverse reactions. Chlorhexidine, Iodine and Chelators are successful against several bacteria and viruses, mainly in retreatment cases. Newer root canal irrigants like MTAD [Mixture of Tetracycline, Acid and Detergent], Tetraclean, Photo-activated disinfection, Electronically Activated Water, Ozonated water and lasers have potential to maximize root canal disinfection. Currently these newer irrigants could be used as an adjunct to NaOCl, while investigators are continuously looking for the subtle ideal root canal irrigant

Caries prevalence among school children age 6-14 years in Gadap town Karachi in relation to the awareness of their parents toward oral health

The aim of this cross sectional study was to determine the prevalence of caries among school children age 6-14 years in Gadap Town, Karachi in relation to the level of knowledge of their parents to the oral health. Total sample size was 265 children from both sexes. Self-administered questionnaire and oral examination was carried out by a single operator. There were 135 boys and 130 girls. The prevalence of dental caries was 71.7%. The mean DMFT score was 2.22 +/- 2.19. The mean DMFT score for male was 2.17 +/- 2.08 whereas the mean DMFT score for female was 2.27 +/- 2.30. Mean DMFT scores recorded for children of parents having poor, satisfactory and good knowledge of oral health was 4.07 +/- 2.17, 1.56 +/- 1.6 and 0.88 +/- 1.53 respectively. Association between Mean DMFT scores and parents knowledge grades was analyzed using Chi-Square test, the results were significant with p- value = 0.000 at 95% CI that is < 0.05
