Evaluation of Biodentine® and Calcium Hydroxide in the Formation of Dentin Bridge in Deep Carious Lesions.

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.
