Thirty-two patients diagnosed with generalized periodontitis were selected, with a total of 655 teeth examined. Each patient\u2019s mouth was divided into four quadrants (the split-mouth model) to be randomly treated with four sessions of gaseous ozone or air. The following clinical variables were recorded: the gingival index, the periodontal clinical attachment loss, the Miller\u2019s mobility index and the clinical improvements, as assessed through the visual analog scale (VAS). In addition, the microorganisms were qualitatively compared. After four weeks of treatment, the teeth of the ozone-treated quadrants showed statistically significant reductions in the gingival index and an improvement in the clinical attachment (p &lt; 0.0001). The same treatment also significantly improved mobility by between 70% and 86% compared to the control group (p &lt; 0.0001). Statistically significant differences were also recorded for the VAS (p &lt; 0.0001). In the qualitative study of the subgingival flora, significant differences were observed (p &lt; 0.0001). The overall results of this trial support the view that ozone treatment is effective and well tolerated in cases of generalized chronic periodontitis.<\/jats:p>","DOI":"10.3390\/jcm11102946","type":"journal-article","created":{"date-parts":[[2022,5,23]],"date-time":"2022-05-23T22:57:22Z","timestamp":1653346642000},"page":"2946","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Ozone in Patients with Periodontitis: A Clinical and Microbiological Study"],"prefix":"10.3390","volume":"11","author":[{"given":"Ana Maria","family":"Ramirez-Pe\u00f1a","sequence":"first","affiliation":[{"name":"Ministerio de Educaci\u00f3n Superior Ciencia y Tecnolog\u00eda Rep\u00fablica Dominicana, Santo Domingo de Guzm\u00e1n 10204, Dominican Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1045-5119","authenticated-orcid":false,"given":"Arturo","family":"S\u00e1nchez-P\u00e9rez","sequence":"additional","affiliation":[{"name":"Cl\u00ednica Odontol\u00f3gica Universitaria, Hospital Morales Meseguer, Marques de los V\u00e9lez, 2\u00b0 Floor, University of Murcia, 30008 Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matilde","family":"Campos-Aranda","sequence":"additional","affiliation":[{"name":"Escuela Universitaria De Osteopat\u00eda, Campus Universitario de Espinardo Edificio C, 2\u00b0 Floor, 30100 Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2608-8739","authenticated-orcid":false,"given":"Francisco Javier","family":"Hidalgo-Tall\u00f3n","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Stomatology, Radiology and Physical Medicine, Universidad Cat\u00f3lica San Antonio de Murcia (UCAM), Av. de los Jer\u00f3nimos, 30107 Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1902\/annals.1999.4.1.1","article-title":"Development of a classification system for periodontal diseases and conditions","volume":"4","author":"Armitage","year":"1999","journal-title":"Ann.
