New minimally invasive strategies, such as the use of lasers to perform highly controlled tissue ablation, have been introduced in dental practice. The aim of this study was to assess and compare treatment with a 2940 nm erbium\/yttrium\u2013aluminum\u2013garnet (Er:YAG) laser versus a conventional rotary treatment during cavity preparation in children with regard to restoration integrity. In a randomized, controlled, blinded trial using a split-mouth design, 40 (9\u201312-year-old) children with 80 carious primary molars were included. The cavity in one quadrant was randomized to be treated conventionally using a bur, while the cavity in the other quadrant was prepared using an Er:YAG laser. At the one-year follow-up, clinical examinations were conducted to assess the integrity of the restorations according to the Ryge criteria. The data were analyzed using SPSS version 22 (IBM Inc., Chicago, IL, USA). The average age of the participants was 9.4 \u00b1 1.29 years. Males accounted for 51.4% of the participants. The Ryge criteria showed clinical success of restorations, and there was no discernible difference between the conventional and laser intervention techniques. Over one year, no statistically significant differences in the clinical integrity based on the Ryge criteria were found following class I cavity preparation in primary teeth with either procedure.<\/jats:p>","DOI":"10.3390\/children10071215","type":"journal-article","created":{"date-parts":[[2023,7,14]],"date-time":"2023-07-14T00:28:06Z","timestamp":1689294486000},"page":"1215","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Restoration Integrity in Primary Teeth Prepared Using Erbium\/Yttrium\u2013Aluminum\u2013Garnet Laser: A Randomized Split-Mouth Clinical Study"],"prefix":"10.3390","volume":"10","author":[{"given":"Raghdah","family":"Abdrabuh","sequence":"first","affiliation":[{"name":"Paediatric Dentistry Department, Faculty of Dentistry, King Abdulaziz University, Jeddah 21589, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1069-6374","authenticated-orcid":false,"given":"Omar","family":"El Meligy","sequence":"additional","affiliation":[{"name":"Paediatric Dentistry Department, Faculty of Dentistry, King Abdulaziz University, Jeddah 21589, Saudi Arabia"},{"name":"Paediatric Dentistry and Dental Public Health Department, Faculty of Dentistry, Alexandria University, Alexandria 21521, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0860-4573","authenticated-orcid":false,"given":"Najat","family":"Farsi","sequence":"additional","affiliation":[{"name":"Paediatric Dentistry Department, Faculty of Dentistry, King Abdulaziz University, Jeddah 21589, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2128-9395","authenticated-orcid":false,"given":"Ahmed Samir","family":"Bakry","sequence":"additional","affiliation":[{"name":"Restorative Dentistry Department, Faculty of Dentistry, King Abdulaziz University, Jeddah 21589, Saudi Arabia"},{"name":"Department of Conservative Dentistry, Faculty of Dentistry, Alexandria University, Alexandria 21521, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8213-8668","authenticated-orcid":false,"given":"Osama M.","family":"Felemban","sequence":"additional","affiliation":[{"name":"Paediatric Dentistry Department, Faculty of Dentistry, King Abdulaziz University, Jeddah 21589, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"20","DOI":"10.4012\/dmj.21.20","article-title":"A study of cavity preparation by Er:YAG laser observation of hard tooth structures by laser scanning microscope and examination of the time necessary to remove caries","volume":"21","author":"Shigetani","year":"2002","journal-title":"Dent.
