Pain Management and Opioid Use

The pulps in 40 permanent premolars with immature apices were extirpated in seven young dogs. The root canals in 20 teeth were left open to the oral environment and the access openings of the other 20 teeth were closed with Cavit. No drug was used in the canals to stimulate or to induce apexification. After 7 to 11 weeks, radiographic and histologic examination showed that complete apical closure had occurred in 85.5% of the canals that were left open and in 50% of those that were closed. It was concluded that drugs such as calcium hydroxide were not necessary to stimulate apical closure in dogs.
