Background: The intrinsic stains can be treated by various measures such as internal bleaching of nonvital teeth, external bleaching of vital teeth. The present study was conducted to compared carbamide peroxide (CP), sodium perborate (SP) and hydrogen peroxide (HP) as bleaching agents in primary and permanent teeth.
Materials & Methods:
Results: The mean color value at day 0 in sub group I A was 9.6, in group IB was 10.4 and in group III A was 11.5, in sub group II A was 10.6, group II B was 10.7 and group III B was 11.3. The difference was non- significant (P> 0.05).The mean color value at day 0 in sub group I A was 3.9, in group IB was 6.8 and in group III A was 9.4, in sub group II A was 8.4, group II B was 8.7 and group III B was 8.8. The difference was non- significant (P> 0.05). The mean color value at day 0 in sub group I A was 2.7, in group IB was 6.5 and in group III A was 8.5, in sub group II A was 7.0, group II B was 7.8 and group III B was 8.3. The difference was non- significant (P> 0.05).
Conclusion: All bleaching found to be equally efficient in discolored primary teeth whereas CP was effective in discolored permanent teeth.
