ABSTRACT
Background and Aim of Study: Early childhood caries is a multifactorial disease process affecting children below 71 months of age and continues to be a global health problem. Stainless steel crowns (SSCs) are widely used and are very popular in pediatric dentistry due to its superiority and durability when compared with multisurface amalgam restorations. However, one of the major disadvantages with these crowns is the poor esthetics. Parents often request for a more esthetic alternative to the SSC. Zirconia crowns are one of the tooth-colored full crown restorations currently available for use in primary teeth. These are available as both preformed and custom-made crowns and show excellent esthetics. However, these require extensive tooth preparation with a subgingival finish lines, which would cause gingival trauma and bleeding during the preparation. The present study uses intraoral scanners for making the custom-made zirconia crowns, which will avoid the conventional impressions. Currently, there are no studies available in pediatric dentistry regarding CAD-CAM crowns. Hence, there is a need for the study. Aim: The aim of this study is to clinically evaluate the performance of preformed SSCs and custom-made zirconia crowns in primary molars. To elicit parental and patient satisfaction with respect to preformed SSCs and custom made zirconia crowns and to radiographically compare the interproximal bone height for 1 year. Methods: The patients were selected with purposive sampling. The tooth of interest was prepared according to the crown it would receive. The upper and the lower arch of the tooth receiving custom-made zirconia crown was scanned using an intraoral scanner. The crowns were cemented using Type 1 glass ionomer cement (GIC) (SSC) and resin modified GIC (custom-made zirconia crown). After the crown placement, the patient and the parent's satisfaction was scaled regarding the time taken, comfort, cost of crown, appearance of crown, etc., using a 5-point Likert scale. A baseline radiograph was taken after crown placement. The patient was recalled every 3 months till 1 year for evaluation (loss of retention, loss of proximal contact, gingival inflammation, opposing tooth wear, and marginal integrity). At the end of 1 year, radiographs were taken to check the interproximal bone. Results: After 1 year evaluation of custom-made zirconia crowns and preformed SSCs in primary molars, it was shown that both SSC and zirconia crowns showed good gingival scores but zirconia crown was better than SSC in improving the gingival health. SSCs showed better results with respect to the opposing tooth wear and marginal adaptability. Parents as well as patients preferred a tooth-colored crown as a treatment option. Conclusion: Custom-made zirconia crowns are comparable to the preformed SSCs and they show better gingival scores and excellent color match.

ABSTRACT
Introduction: Different sizes of crowns may be tried on children since there is no universal crown size because of distinctions in tooth morphology from one child to other. During the process of trial and error, the crown gets contaminated which needs to be sterilized for reuse of crown. This study was carried out to evaluate the physical–mechanical outcome after the sterilization and disinfection of pediatric preformed crowns. Materials and Methods: In total, sixty crowns consisted of 20 each, stainless steel crowns (SSCs) (3M ESPE), preveneered stainless steel (Kinder Krowns), and Zirconia crowns (Kinder Krowns) which were divided into four groups. G1 in which crowns did not undergo any sterilization, G2 consisted of fast sterilization, similarly G3 was slow sterilization, and G4 underwent chemical disinfection using Korsolex Plus for 15 min. Following sterilization, all the crown samples were observed under a stereomicroscope at ×200 magnification and assessed for color change, crazing, dimensional stability, and fracturing. Post hoc Tukey test and two-way ANOVA were performed for comparison between types of crowns and sterilization methods, with a significance level was set at P < 0.05. Results: There was no color change or fracturing following sterilization among crowns in any of the groups. Highest crazing was noted in stainless steel and the least in Zirconia crowns. Preveneered stainless steel was the most dimensionally stable and SSCs was the least. Conclusion: No color changes and fracture were noted in any type of crowns. Preveneered stainless steel was most dimensionally stable followed by Zirconia and SSCs. Maximum crazing was seen in SSCs and nil in Zirconia.
ABSTRACT
El propósito de este artículo es mostrar una alternativa más dentro de las que en la actualidad existen para restaurar la zona anterior, mediante el uso de coronas de acero cromo con un frente estético ceramizado mediante Art-glass®. Se presenta el caso clínico de un paciente de sexo masculino de 1 año y 10 meses de edad, el cual presenta caries por alimentación infantil, con destrucción coronal de los cuatro incisivos temporales superiores. El plan de tratamiento consistió en el tratamiento pulpar mediante la realización de una pulpectomía para obturar el conducto con Vitapex®, dos pulpotomías y la restauración de los cuatro dientes anteriores mediante la colocación de coronas de acero cromo con Art-glass®. Estas coronas son una excelente opción para una restauración estética, debido a que se cuenta con una gran gama de colores, es de fácil fabricación y al ser una técnica indirecta, nos permite dejar un espacio libre de cerómero para lograr un buen ajuste coronal.
The aim of this article is to present an additional alternative to restore the anterior zone, using crowns of steel chromium with a ceromer aesthetic front by means of Art-glass®. It is presented a clinical report of a masculine patient of 1 year 10 months of age, with early childhood dental caries, with coronal destruction of the four deciduous superior incisors. The treatment planning consisted of pulpar treatment with pulpectomy and endodontic obturation with Vitapex®, two pulpotomies and the restoration of these with steel chromium crowns with Art-glass®. These crowns are an excellent option for an aesthetic restoration, because of its great variety of colors, its easy manufacture, and being an indirect technique allows leaving a free space of ceromer to obtain a good coronal adjustment.

Esta revisão de literatura tem como objetivos descrever essa técnica protética restauradora e fornecer subsídios ao odontopediatra e ao clínico geral para corretas indicações clínicas do material, baseados em resultados clínicos e laboratoriais publicados nos últimos anos.
Stainless Steel Crowns: Technique and Cost Effectiveness. Use of stainless steel crowns corresponds to the most efficient prosthetic technique to accomplish large coronal reconstructions in deciduous and young permanent teeth. The aims of the current literature review are to describe this restorative technique and to offer subsidies for correct clinic indications of the material to pediatric and general dentists, based on clinical and laboratorial results published in last years.
