Restoration of severely mutilated primary anterior teeth

ABSTRACT

One of the most prominent sequelae of severe form of early childhood caries is the mutilation of primary anterior teeth. Restoration of these teeth presents a challenge to the pediatric dentist. Restoration of these teeth usually involves pulpectomy followed by restoration of the coronal portion of the tooth by composite restoration. Different treatment modalities were tested in this study to compare the shear bond strength of such modalities. Sixty bovine primary anterior teeth were used in this study divided into six equal groups. These groups were classified according to the preparation and restoration following the loot canal treatment into Composite core group [gp I]. Composite with undercut [gp II], wire with undercut [pg III]. wire group [gp IV], polycarbonate post [gp V], fiber post [gp VI]. Groups were subjected to shear strength test by beam compression technique. Results showed that statistically there was no significant difference between different groups but the wire with undercut [gp III] showed the highest mean shear bond strength values, and gave a high percentage difference when compared with other groups, this was followed by composite with undercut group [81.83%], wire group [74.33%], composite core group [65.92%], polycarbonate post [61.35%], and lastly fiber post group [59.62%]
