Clinical Evaluation of Maneuverability and Durability of Titanium Nitride-coated Preformed Crown on Primary Molar Teeth: A Randomized Controlled Trial.

Abstract

The management of multisurface carious primary molar is challenging. Currently, the ideal choice for the management of extensive multi-surface carious primary molar is the placement of a preformed stainlesssteel crown (SSC)/preformed zirconia crown. Unfortunately, conventional preformed SSCs are frequently refused by parents for esthetic reasons, while the preformed zirconia crown has its own disadvantages like high cost and excessive tooth preparation. To evaluate the maneuverability and durability of titanium nitride-coated crowns on primary molar teeth and to assess the child-parent satisfaction of titanium nitride-coated gold-colored preformed crowns over metal-colored preformed SSC on primary molar teeth. Randomized controlled trial conducted on children between the age-groups of 6- and 9-year-old children. Group I for titanium nitride-coated preformed crown and group II for preformed SSC (control group) were allotted with a simple random technique. The maneuverability of the titanium nitride-coated crowns was evaluated in comparison with preformed SSC in terms of the level of difficulty while trimming, contouring, crimping, and wearing out of titanium nitride coating while manipulating. Participants of group I were recalled for follow-up in the 1st, 6th, and 12th months to evaluate the durability of the titanium nitride coating on the preformed crowns. There were no failures at the 12-month follow-up in terms of the durability of the titanium nitride coating, and there was no significant difference seen in terms of the maneuverability of both crowns. Overall, child-parent satisfaction was good with gold-colored titanium nitride-coated crowns. The study concluded that titanium nitride-coated gold crowns could be a boon to pediatric dentistry and serve as an alternative to metal-colored SSCs. Vundela RR, Gupta N, Balamurugan S, et al.
