Brief Summary:
Dental caries is an infectious disease mediated by a consortium of microbes in the oral cavity. The disease is characterized by demineralization of the tooth, if untreated, it leads to cavitation, discomfort, pain and eventual tooth loss. Frequently, complete caries removal of dentine carious lesions leads to exposure of the pulp affecting its vitality. Therefore, it is crucial that vitality of the teeth is preserved causing little damage to the pulp. Different approaches have been used to reduce or eliminate microorganisms underneath the restorations. Chlorhexidine has a strong antibacterial effect, particularly on planktonic bacteria. Its effect on bacterial biofilms is compromised, however The objective of this study is to examine the in vivo effect of diamine silver fluoride, potassium iodide and their mixture on bacteria present in deep carious lesions. Dentine samples from 5 carious lesions from each of 5 patients before and after treatment with test agents will be collected in pre-reduced sterile Ringer's solution and processed for microbiological evaluation. The samples after serial dilution and plating will be incubated in aerobic, anaerobic and CO2 atmosphere for 2-5 days. Colony forming units will be enumerated and the effect of antibacterial agents in question on the bacterial viability in carious lesions will be assessed.
