[The dental pulp reaction to microbial action in different methods of treating the carious cavity].

Under study were the effects of bacterial stimulation of prepared dentin on dental pulp. Traditional method of drug treatment of prepared cavity with alcohol and either was compared with methods reducing dentin permeability making use of calcium hydroxide, potassium nitrate, and calcium oxalate. Inflammatory reaction of the pulp was more pronounced after traditional treatment. Reduction of dentin permeability with agents blocking dentin tubes reduced the severity of inflammatory reaction.
