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.

多面龋坏的乳磨牙治疗颇具挑战性。目前,广泛多面龋坏乳磨牙治疗的理想选择是放置预成不锈钢冠(SSC)/预成氧化锆冠。遗憾的是,传统预成SSC常因美观原因被家长拒绝,而预成氧化锆冠有成本高和牙体预备过多等自身缺点。
评估氮化钛涂层冠在乳磨牙上的操作性和耐用性,并评估家长和儿童对乳磨牙上金色氮化钛涂层预成冠相对于金属色预成SSC的满意度。
对6至9岁儿童进行随机对照试验。采用简单随机技术将第I组(氮化钛涂层预成冠)和第II组(预成SSC,对照组)进行分配。将氮化钛涂层冠的操作性与预成SSC在修整、塑形、卷边以及操作时氮化钛涂层磨损方面的难度水平进行比较评估。第I组参与者在第1、6和12个月进行随访,以评估预成冠上氮化钛涂层的耐用性。
在12个月随访时,氮化钛涂层的耐用性方面没有失败情况,两种冠的操作性方面也没有显著差异。总体而言,家长和儿童对金色氮化钛涂层冠的满意度良好。
该研究得出结论,氮化钛涂层金冠可能是儿童牙科的一项福音,可作为金属色SSC的替代品。
