Bacterial invasion of acid‐etched and non‐acid‐etched dentin was compared in teeth with intact pulps and in teeth with experimentally induced pulpal inflammation. In 37 pairs of teeth from 3 dogs, class V cavities were prepared. In 1 tooth from each pair, pulpal inflammation was induced by the application of a strong thermal irritant to the floor of the cavity. In 18 pairs of teeth the cavity floor was treated with orthophosphoric acid, and in 19 pairs with normal saline. The cavities remained open to oral microflora for a period of either 3 or 7 d. All the teeth with acid‐etched dentin and only 9 teeth with non‐acid‐etched dentin exhibited slight invasion of the dentinal tubules by gram‐positive or gram‐negative bacteria. This invasion had no relationship to the histopathological findings in the pulp
