ABSTRACT
BACKGROUND: Indirect pulp capping is the main treatment modality for reversible pulpitis.
OBJECTIVE: To evaluate the efficacy of Biodentine® and Calcium hydroxide in the formation of dentin bridge.
MATERIALS AND METHODS: A double blinded, randomized clinical control trial involving 50 consenting subjects, aged 16 to 55 years with deep carious vital teeth. It was a comparative study with intervention comparing Biodentine® (test) and Calcium hydroxide (control). Subjects’ teeth were assessed for normal response to pulp testing. Cavity preparation was done and the cavity was dressed with either Biodentine® or Calcium hydroxide (Ca(OH)2) then restored with Glass ionomer cement. A bitewing digital dental x-ray was taken at the end of the procedure to measure radiographically the dentin depth as base line using a digital meter. The subjects’ teeth were examined radiographically at three, six and nine months. The probability level of p<0.05 was considered significant.
RESULTS: There was a progressive increase in dentin formation at three months, six months and a significant increase at nine months: the subjects’ teeth in the Biodentine® group recorded an increase in dentin depth of mean 0.67±0.07mm in the mesial aspect and mean 0.66±0.07mm in both the middle and distal aspects. The Ca(OH)2 group recorded an increase in dentin depth of mean 0.55±0.07mm in the mesial aspect, mean 0.52±0.07mm in the middle aspect and mean 0.55±0.07mm in the distal aspect at nine months. (p value 0.001).
CONCLUSION: Biodentine® and Ca(OH)2 have proven to be efficacious in dentin bridge formation. The Biodentine® group showed a statistically significant increase in mean dentin depth relative to that of Ca(OH)2 group following indirect pulp capping of deeply carious teeth.
