Abstract
  • Vital pulp therapy (VPT) is a conservative treatment option for exposed pulps with the goal of preserving the vitality of the pulp (1). Historically, VPT with calcium hydroxide had inconsistent success rates when used for carious exposures. Since that time, newer materials have resulted in a more favorable success rate for this treatment option. Factors in addition to the material type may affect the outcome that previous studies with small sample sizes did not identify (2, 3). This prospective, observational study aims to examine the correlation between the outcome of vital pulp therapy and pre-operative factors such as patients’ gender, age, tooth type, and the site of pulp exposure. Written informed consent was obtained from asymptomatic patients experiencing a pulp exposure on a vital, mature permanent tooth. Caries removal was completed and hemorrhage was controlled with sodium hypochlorite. Mineral trioxide aggregate was placed on the exposed pulp and the tooth was restored permanently. The patients were followed up with a series of phone calls and in person examinations at 6 months and 1 year postoperatively. The data was analyzed by logistic regression using a generalized linear model to evaluate associations between pre-operative factors and outcome of treatment. A total of 73 patients were treated with ages between 15 and 78 years old. 51 patients were available for 6 month recall with a success rate of 79%. This study found that vital pulp therapy on mature, permanent teeth was a viable treatment and there was no association between the examined pre-operative factors and the outcome.
