Abstract
OBJECTIVE To compare the different restoration types of primary teeth to determine which type is appropriate for extensive caries of primary molars and incisors based on mechanical properties. MATERIALS AND METHODS A total of 160 primary teeth were evaluated in this study, including 80 incisors and 80 molars. Each category was divided into four groups: the control group, composite resin group, pre-veneered stainless steel crown (stainless steel crown) group, and zirconia crown group. Compressive strength test and fatigue strength test were performed. RESULTS The compressive strength and fatigue strength of the composite resin group were significantly decreased compared with the control group (P < 0.05). The prefabricated crown groups showed increased fatigue and compressive strength compared with the control group, and the zirconia crown group was higher than that of the pre-veneered stainless steel crown group (P < 0.05). The zirconia crown group was less than the stainless steel crown group (P < 0.05) in the compressive strength but more than the stainless steel crown group (P < 0.05) in the fatigue strength. CONCLUSIONS The compressive strength and fatigue strength of crown restoration were superior to that of the composite resin filling. The fatigue strength of the zirconia crown also performed better than the pre-veneered stainless steel crown and the stainless steel crown. The compressive strength of the zirconia crown was less than that of the stainless steel crown. CLINICAL RELEVANCE The zirconia crown is a new restoration method for primary teeth that may be commonly applied in clinical practice.

Exploring Parent's Satisfaction and the Effectiveness of Preformed Metal Crowns Fitting by Hall Technique for Carious Primary Molars in Jeddah Region, Saudi Arabia: Findings of a Prospective Cohort Study. Patient Prefer Adherence 2022; 16:2497-2507. [PMID: 36105659 PMCID: PMC9467849 DOI: 10.2147/ppa.s370159] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2022] [Accepted: 08/25/2022] [Indexed: 12/03/2022] Open
Abstract
PURPOSE The Hall technique (HT) is a non-invasive approach to treating carious primary teeth. Its acceptability by parents and effectiveness is not widely known in the Middle East. Therefore, we aimed to conduct this study to explore the effectiveness of preformed metal crowns (PMCs) fitting by HT and to what extent the parent's satisfaction for their children in Jeddah region. MATERIALS AND METHODS A prospective cohort study was conducted in the outpatient pediatric dental clinic at Jeddah Specialty Dental Center, in 2018. The cohort of children was exposed to the HT and was recalled 3 months to two years later to examine present or absence of: crown loss, open margin, signs or symptoms of reversible or irreversible pulpitis, and if the tooth exfoliated naturally. Parents who agreed to undergo the HT for their children completed a 5-point Likert questionnaire after treatment and after three months. RESULTS A total of 48 children (72 teeth) were initially enrolled, but only 25 children (49 teeth) completed two years of follow-up. At 2 years follow-up, one PMC was lost (2.04%) while no teeth fitted with the HT required any further intervention. Around 96% of parents were satisfied with this procedure and 92% wanted other carious teeth to be treated similarly. All parents were satisfied with this technique because it did not include local anesthesia and no drilling. It was found that parents of girls were satisfied more than parents of boys and on average their satisfaction score at the time of treatment was 3.04 units higher than parents of boys with a significant p-value of 0.02 and 95% CI for the beta coefficient to be 0.46 to 5.62. CONCLUSION The HT is effective as a treatment of dental caries and it was generally accepted by parents initially and during their follow-up visits.
