Abstract:
Objective:To investigate the efficacy of vital pulp therapy versus pulp revascularization in the treatment of irreversible pulpitis and apical periodontitis in young permanent teeth. Methods:This study used a retrospective design. Fifty-six children with irreversible pulpitis and apical periodontitis in young permanent teeth, admitted to Shaoxing Stomatological Hospital from January 2022 to June 2024, were selected for the study. The children were divided into Group A ( n = 28) and Group B ( n = 28) based on treatment methods. Group A received vital pulp therapy, while Group B underwent pulp revascularization. The efficacy of both groups was compared 12 months after surgery. The root length and apical foramen size were compared between the two groups before surgery, as well as 3 and 12 months after surgery. The imaging findings were also compared between the two groups 3 and 12 months after surgery. Results:There was no significant difference in efficacy between the two groups ( P>0.05). The root lengths in Group A at 3 and 12 months after surgery were (13.17 ± 1.52) mm and (14.34 ± 1.68) mm, respectively, which were significantly greater than those in Group B [(11.86 ± 1.29) mm, (13.09 ± 1.45) mm; t = 3.48, 2.98, both P<0.05]. The apical foramen sizes in Group A at 3 and 12 months after surgery were (2.17 ± 0.32) mm and (1.61 ± 0.27) mm, respectively, and were significantly smaller than those in Group B [(2.53 ± 0.37) mm, (1.98 ± 0.31) mm; t = -7.03, -4.76, both P<0.05]. The proportion of children with an open apical foramen in Group A at 3 months after surgery was significantly lower than that in Group B [35.71% (10/28) vs. 64.29% (18/28); χ2 = 4.57, P<0.05). However, there was no statistically significant difference in the proportion of open apical foramina between the two groups at 12 months after surgery ( P>0.05). Conclusions:Vital pulp therapy shows good efficacy in the treatment of irreversible pulpitis and apical periodontitis in young permanent teeth. Compared with pulp revascularization, vital pulp therapy can remarkably reduce apical foramen size and increase root length, making it a valuable option for clinical practice.
