| Summary: | <h3>Background</h3><p dir="ltr">Preformed metal crowns (PMCs) have been used to restore carious primary molars and have a high success and survival rate. There are two methods currently employed for PMC placement ‐ the conventional technique (CT) and Hall technique (HT).</p><h3>Aim</h3><p dir="ltr">This systematic review aims to compare the outcomes of PMCs placed using the CT and HT.</p><h3>Design</h3><p dir="ltr">This systematic review was conducted according to the Preferred Reporting Items for Systematic Review and Meta‐analysis statement. A literature search of five databases was performed up to 23 August 2022. Clinical studies comparing carious primary molars restored with PMCs using either technique with a minimum 12‐month follow‐up were included. Risk of bias (RoB) assessment was performed using the National Institutes of Health Quality Assessment tool.</p><h3>Results</h3><p dir="ltr">Five articles met the inclusion criteria, and four were included for meta‐analysis. The 12‐ and 24‐month success and survival rates were above 85% for both groups, with no significant differences shown at 12 and 24 months. The HT requires a shorter treatment duration, is more cost‐effective and has a high level of acceptability among parents when compared to the CT. Four articles were rated fair, and one article was rated good in the RoB assessment.</p><h3>Conclusion</h3><p dir="ltr">Greater consideration may be given towards using the HT as part of standard treatment procedures in managing carious primary molars. Future studies should standardise reporting of outcomes to facilitate a more homogeneous pool of data for future meta‐analysis.</p><h2>Other Information</h2><p dir="ltr">Published in: International Journal of Paediatric Dentistry<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1111/ipd.13029" target="_blank">https://dx.doi.org/10.1111/ipd.13029</a></p> |
