The current study aimed at evaluating the application of this laser versus conventional instruments in periodontal pocket reduction flap surgery. Methods: Eight patients (16 dental arches) requiring periodontal surgery were included (Trial registration number: IRCT201711129014N199). Using a split-mouth study design, two posterior sextants of a dental arch were randomly allocated into either a test group, open flap debridement periodontal surgery using the Er,Cr:YSGG laser or a control group using the conventional method. Laser parameter settings of a 2780 nm wavelength, H mode (60 \u00b5s pulse duration), 25-50 Hz, 2-3.5 W output powers and Air-20%, Water-60-80% were applied and adjusted individually for each step of the flap surgery procedure. Baseline, 1 and 3-month measurements of plaque index (PI), Gingival Index (GI), gingival recession (GR), probing depth (PD) and clinical attachment level (CAL) were recorded for comparisons. Data were analyzed by a linear model for correlated data using the generalized estimating equations (GEE) method and the least significant difference (LSD). Results: In both treatment groups, reductions in PI and GI were observed in the 3-month follow-up period. These indices were significantly lower in the laser-treated sides compared to the conventional group (P&lt;0.05). The Mean PD and CAL were lower at 1 month and 3 months compared to the baseline in both groups (P&lt;0.05). However, these parameters were not statistically different in the treatment groups during these follow-up timelines. An increase in GR was observed from the baseline to 1 month and 3 months with less recession in the laser-treated sides (P=0.016). Conclusion: Based on the results of the present study, the Er,Cr:YSGG laser assisted periodontal flap surgery resulted in similar treatment outcomes to the conventional method and may be considered as a safe and effective treatment modality.<\/jats:p>","DOI":"10.34172\/jlms.2022.04","type":"journal-article","created":{"date-parts":[[2022,4,5]],"date-time":"2022-04-05T07:29:12Z","timestamp":1649143752000},"page":"e4-e4","update-policy":"https:\/\/doi.org\/10.34172\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Efficacy of the Er,Cr:YSGG Laser Application Versus the Conventional Method in Periodontal Flap Surgery: A Split-Mouth Randomized Control Trial"],"prefix":"10.34172","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4933-7520","authenticated-orcid":true,"given":"Parviz","family":"Torkzaban","sequence":"first","affiliation":[{"name":"Department of Periodontics, School of Dentistry, Dental Research Center, Hamadan University of Medical Sciences, Hamadan, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2049-6547","authenticated-orcid":true,"given":"Iman","family":"Barati","sequence":"additional","affiliation":[{"name":"Department of Periodontics, School of Dentistry, Hamadan University of Medical Sciences, Hamadan, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5514-3584","authenticated-orcid":true,"given":"Javad","family":"Faradmal","sequence":"additional","affiliation":[{"name":"Modeling of Noncommunicable Diseases Research Center & Department of Biostatistics, School of Public Health, Hamadan University of Medical Sciences, Hamadan, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6072-7055","authenticated-orcid":true,"given":"Somayeh","family":"Ansari-moghadam","sequence":"additional","affiliation":[{"name":"Department of Periodontics, School of Dentistry, Zahedan University of Medical Sciences, Zahedan, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5287-1754","authenticated-orcid":true,"given":"Leila","family":"Gholami","sequence":"additional","affiliation":[{"name":"Department of Periodontics, School of Dentistry, Dental Research Center, Hamadan University of Medical Sciences, Hamadan, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"20123","published-online":{"date-parts":[[2022,1,25]]},"container-title":["Journal of Lasers in Medical Sciences"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sbmu.ac.ir\/jlms\/article\/view\/34822\/28650","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sbmu.ac.ir\/jlms\/article\/view\/34822\/28650","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,4,5]],"date-time":"2022-04-05T07:29:12Z","timestamp":1649143752000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sbmu.ac.ir\/jlms\/article\/view\/34822"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,1,25]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2022,1]]}},"URL":"https:\/\/doi.org\/10.34172\/jlms.2022.04","relation":{},"ISSN":["2008-9783","2228-6721"],"issn-type":[{"value":"2008-9783","type":"print"},{"value":"2228-6721","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,1,25]]},"assertion":[{"value":"Laser Application in Medical Sciences Research Center","name":"journal_owner","label":"Journal Owner"},{"value":"Laser Application in Medical Sciences Research Center","name":"journal_publisher","label":"Journal Publisher"},{"value":"2021-05-09","order":1,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2021-10-16","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2022-01-25","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
