Abstract Purpose This retrospective cohort observational study evaluated marginal integrity, gingival health and aesthetics of zirconia crowns (ZC) placed on primary maxillary anterior teeth at 6- to over 30-month follow-up visits. Methods Two independent raters evaluated radiographic and photographic findings in 131 ZC placed in 36 children aged 24.8–62.2 months (median = 40.6) who had at least one recall visit 6 months after placement. Follow-up periods were stratified into three levels: long, intermediate and short. Associations between crown performance and crown brands, follow-up periods, treatment performed under general anaesthesia or sedation and previous pulpotomy were investigated by ordinal logistic regression. Results Follow-up ranged from 6 to 33.8 months (average: 13.5 months). Marginal integrity was highly rated in 82.4% of the teeth. No gingivitis was found in 35% of the teeth, 58% showed mild gingivitis and 7% showed moderate gingivitis (p = 0.06). Colour match and crown contour were rated very high in 55% of the cases. Marginal integrity and periodontal health differed between cases performed under general anaesthesia and those performed under sedation (p = 0.03 and p = 0.003, respectively). Pulpotomized teeth showed worse colour matching with the adjacent teeth than non-pulpotomized teeth (p = 0.03). Conclusions Our findings suggest that ZC comprise a satisfactory treatment option for carious primary maxillary incisors, presenting good overall marginal integrity, gingival health, and aesthetics.

Introduction Paediatric dentists encounter an increased request among parents for improved aesthetic solutions while restoring their children’s teeth (Waggoner 2015; Liu and Donly 2016). The aesthetic full coverage crowns for primary anterior teeth that are available for restoration can be divided into two categories: those that are bonded onto the tooth such * M.

as resin composite strip crowns (RCSC) and those that are preformed and retained on the tooth by luting cement (Waggoner 2015). The later include pre-veneered stainless steel crowns (VSSC) (Oueis et al. 2010) and the newer zirconia crowns (ZC) (Liu and Donly 2016). Historically, one of the most popular options has been the RCSC whose advantages include
