PAD (Group I), CH (Group II) and PAD followed by CH application (Group III). Three study groups were defined on the basis of the material applied, i.e. In this context, it is desirable to investigate an effective way of disinfecting the remaining carious dentin.Įthical clearance was obtained from the Institute Research Ethics Committee (Ref. However, determining the extent of carious tissue excavation and achieving long-term seal by current restorative materials remain a pitfall. This creates the conditions for caries arrest and remineralization. Adequate disinfection is accomplished by physical removal of the infected dentin and entombing the remaining microbes. Another pre-requisite for favorable outcome in IPT is an effective coronal seal. 4, 5 This implies that the success of this technique is not dependent on the material applied per se, but on an effective antimicrobial treatment of the deep layers of carious dentin. have documented similar clinical, radiographic, microbiological and ultra-structural outcome of IPT performed with either CH or inert materials. Calcium hydroxide (CH) has emerged as the "gold standard" with a success rate of 92 - 97%. Role of remineralizing materials in IPT have been widely investigated, but with conflicting conclusions.
