Vital Pulp Therapy In Primary Teeth With Chronic Hyperplastic Pulpitis

To assess the treatment effectiveness of vital pulp therapy (VPT) in primary teeth with chronic hyperplastic pulpitis and to investigate potential factors. This retrospective study included patients who experienced chronic hyperplastic pulpitis and accepted VPT from 2021 to 2023 with at least 6 months of follow-up. All primary teeth were treated with pulpotomy, pulp prognosis of teeth was evaluated according to clinical symptoms and radiological examinations. Totally 36 patients/cases were included (15 males and 21 females) in the present study which the average age of patients was (5.8± 1.7) years old and the median follow-up is 13 months (6-20 months). The success rate of primary teeth with chronic hyperplastic pulpitis accepted VPT is 86.11%. Among 5 failed cases, 3 teeth were showed abnormal radiographic manifestation at the 10 and 16 months visits while another 2 case appeared abnormal mobility but normal radiograph at the 10-month visit. The present study found vital pulp therapy in primary teeth with chronic hyperplastic pulpitis had a relatively good prognosis. VPT might be an option in treating immature teeth with chronic hyperplastic pulpitis, which need more researches.
