Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.

Intervention categories, outcome domains and clusters are a proposed key pending human validation. Clear all filters

Question	Effect	Evidence	Status / GRADE
Hall Technique (sealing with a preformed metal crown) vs Non-restorative cavity control (NRCC) Efficiency, costs or cost-effectiveness · Children and/or adults with permanent or primary teeth, vital (sensitive) pulps, and cavitated or dentine carious… · Primary dentition Interventions for treating cavitated or dentine carious lesions (2021) · Cochrane	Cost-effectiveness reported narratively: HT found more cost-effective than NRCC in primary teeth (Santamaria 2018); not GRADE-rated.	1 study	Ungraded
Single full-coverage metal-ceramic crown over composite core and post vs Direct adhesive composite restoration with post (conventional filling, no crown) Costs for the use of different treatment interventions · People with a permanent tooth that has undergone endodontic (root canal) treatment Single crowns versus conventional fillings for the restoration of root‐filled teeth (2015) · Cochrane	No data were reported nor measured by the study. The abstract confirms no evidence was available for any secondary outcome.	NR	No studies
Preformed metal crown (fitted using the Hall Technique) vs Non-restorative caries treatment Cost · Children with decayed primary molar teeth Preformed crowns for decayed primary molar teeth (2015) · Cochrane	The studies did not measure this outcome.	0 studies	No studies
Preformed crown (any material; conventional technique or Hall Technique) vs Filling (any material; with or without complete carious tissue excavation; with or without pulp treatment) Cost · Children with decayed primary molar teeth Preformed crowns for decayed primary molar teeth (2015) · Cochrane	The studies did not measure this outcome.	0 studies	No studies
