245 - Success Rate of Primary Teeth MTA Pulpotomies

Purpose: The aim of this retrospective record review was to determine the success rate of primary teeth pulpotomies completed with mineral trioxide aggregate (MTA) and sodium hypochlorite at the Lincoln Ave pediatric dental clinic in Yakima, Washington.

Methods: Data was collected via the electronic dental record Epic utilizing the Current Dental Terminology (CDT) D3320 pulpotomy code for completed treatment under general anesthesia or in clinical setting between October 1, 2019 and September 30, 2021. Retrieved charts were screened to meet inclusion criteria. Data was sorted and statistically analyzed. The significance level was set at P <.05.

Results: A total of 76 charts with 106 pulpotomies met inclusion criteria. There were 43 females and 33 males with a mean age of 4.16±1.05 years old. Pulpotomies completed were 92.5% under general anesthesia and 7.5% in clinical settings. Primary tooth type included 41.5% first molars and 58.5% second molars. There was no statistical difference for clinical or radiographic success in terms of treatment setting or tooth type. Clinical success was 98.1% with 1.9% clinical failure. Radiographic success was 96.2% with 3.8% radiographic failure. Distribution of clinical and radiographic variables was significantly different (P <.05).

Conclusions: There is a significant difference between the distribution of clinical and radiographic variables (p <.05). MTA is a reliable material for primary teeth pulpotomies. Future efforts should focus on further investigating pulpotomy techniques and success rates.
