description | Introduction: Smear layer removal from the root canal wall
involves the use of 17% EDTA and 5.25% sodium hypochlorite,
which thereby improves the adhesion of obturating materials to
root dentin. But these chemical irrigants have shown to decrease
micro hardness, increase roughness, cause erosion and reduce
the root dentin fracture toughness. To combat these adverse
effects, studies can be focussed on the remineralisation of the
erosive root dentin and this novel idea has been utilized in the
present study.
Aim: To evaluate the micro hardness of erosive root dentin
when Casein Phosphopeptide–Amorphous Calcium Phosphate
(CPP-ACP) was used as a final irrigant and its influence on resin
sealer bonding tested by push-out bond strength method.
Materials and Methods: Sixty extracted maxillary incisors were
divided into three groups based on the final irrigation protocol.
Group 1-normal saline, Group 2-17% EDTA (Ethylene Diamine
Tetraacetic Acid) + 5.25% NaOCl (Sodium Hypochlorite),
Group 3 - 17% EDTA + 5.25% NaOCl + CPP-ACP; each group
was divided into two subgroups. Half the specimens of each
group were evaluated for Vicker’s micro hardness test after
the treatment. In continuation with the above methodology the
remaining specimens were tested for push-out bond strength
after obturation of the specimens with self etch adhesive resin
sealer and conventional 6% gutta percha cones.
Results: Micro hardness was statistically analysed using
Kruskal Wallis test and push-out bond strength was evaluated
using Mann Whitney test and paired t-test. CPP-ACP treated
group showed increased micro hardness (p<0.05). There was
no statistically significant difference between the push-out
bond strength values between group EDTA + NaOCl group and
EDTA + NaOCl + CPP-ACP group.
Conclusion: Within the limitations of this study it can be
concluded that, CPP-ACP improved the micro hardness
of erosive root dentin and is not affecting its bond strength.
Therefore, CPP-ACP may be used before bonding procedures
for promoting remineralization of root dentin. |
