[Evaluation of bioceramic putty repairment in primary molars pulpotomy].

OBJECTIVE

To evaluate the clinical characteristics and effectiveness of bioceramic putty repairment (iroot BP Plus) used as pulp capping agents on pulpotomy in primary molars.

METHODS

Forty primary molars were treated by pulpotomy with bioceramic putty repairmen as the pulp capping agents at the Third Clinical Division of Peking University School and Hospital of Stomatology, from September 2016 to September 2017. The children who were followed up over one year were selected as the subjects of this study. The teeth were checked clinically and radiographically during fixed intervals, and classified into one of five outcomes: N, H, P, P, P. N, absence of clinical symptoms, and absence of apical radiolucency; H, absence of clinical symptoms, and nonpathologic radiographic change present; P, absence of clinical symptoms, and pathologic change present, no need for treatment; P, present or absence of clinical symptoms, pathologic change present treatment or extract immediately; P, premature loss of deciduous tooth. Molars classified into N and H were regarded as successful, classified into P, P and P were regarded as failed.

RESULTS

Followed up for 12-24 months (the average follow up time was 16months), thirty four children were finally included, aged from 3.1 years to 8.5 yaers (the average age was 4.3 years), forty primary molars were included. Thirty four primary molars were included into N group, with absence of clinical symptoms, absence of apical radiolucency. Two molars were included into H group with physiological root absorption. One molar was included into Pgroup with absence of clinical symptoms butinternal absorption of the root. Three molars were included into P group, with gingival fistula and apical radiolucency. None was included into P group. Thirty six teeth got successful treatment, four molars failed. One year success rate of pulpotomy of primary molars using bioceramic putty repairment was 95%.

CONCLUSION

Current evidence suggests that bioceramic putty repairment as a pulpotomy medicament showed satisfied clinical and radiographic result in pulpotomy of primary molars. Bioceramic putty repairment is an acceptable material when used in pulpotomy of primary molars.
