Methods: A total of 24 SS and 24 zirconia drills were treated with 3 different sterilization processes: 50 cycles of immersion in glutaraldehyde 2%, 50 cycles in 6% hydrogen peroxide and 50 cycles of heat. Energy-dispersive X-ray spectroscopy (EDX) was used to compare the effect of the different treatments compared to new untreated controls. Infrared thermography was used to measure the increase of temperature during drilling on bone ribs. A scanning electron microscopy (SEM) was used to measure the roughness of the samples. Results: Zirconia drills seem not to be affected by the different treatments; no significant differences were found with EDX nor through thermography controls. SS drills were affected by the different treatments, as confirmed by the increased roughness of the SS samples after all the cycles of sterilization\/disinfection, measured at SEM. On the contrary, the zirconia drills roughness was not particularly affected by the chemical and thermal cycles. Significant differences were observed regarding the temperature, between steel and zirconia drills (p &lt; 0.01). Conclusions: The disinfection agents had a weak impact on the temperature changes during implant bone preparation, while heat sterilization processes had no effect on either of the drills evaluated. The disinfection agents increased the roughness of the steel drills, while they had no effect on the zirconia drills.<\/jats:p>","DOI":"10.3390\/jcm9041019","type":"journal-article","created":{"date-parts":[[2020,4,7]],"date-time":"2020-04-07T03:58:39Z","timestamp":1586231919000},"page":"1019","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["The Effects of Liquid Disinfection and Heat Sterilization Processes on Implant Drill Roughness: Energy Dispersion X-ray Microanalysis and Infrared Thermography"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1374-6146","authenticated-orcid":false,"given":"Antonio","family":"Scarano","sequence":"first","affiliation":[{"name":"Department of Medical, Oral and Biotechnological Sciences, University of Chieti-Pescara, 66100 Chieti, Italy"},{"name":"International Academy of Ceramic Implantology, Silver Spring, MD 20901, USA"},{"name":"Department of Oral Implantology, Dental Research Division, College Ing\u00e0, UNING\u00c1, Cachoeiro de Itapemirim 29312, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3849-4304","authenticated-orcid":false,"given":"Morena","family":"Petrini","sequence":"additional","affiliation":[{"name":"Department of Medical, Oral and Biotechnological Sciences, University of Chieti-Pescara, 66100 Chieti, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3746-5675","authenticated-orcid":false,"given":"Filiberto","family":"Mastrangelo","sequence":"additional","affiliation":[{"name":"Clinical and Experimental Medicine, Medical School, University of Foggia, Via Antonio Gramsci, 89, 71122 Foggia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5023-3265","authenticated-orcid":false,"given":"Sammy","family":"Noumbissi","sequence":"additional","affiliation":[{"name":"Department of Medical, Oral and Biotechnological Sciences, University of Chieti-Pescara, 66100 Chieti, Italy"},{"name":"International Academy of Ceramic Implantology, Silver Spring, MD 20901, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2660-9231","authenticated-orcid":false,"given":"Felice","family":"Lorusso","sequence":"additional","affiliation":[{"name":"Department of Medical, Oral and Biotechnological Sciences, University of Chieti-Pescara, 66100 Chieti, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,4,4]]},"reference":[{"key":"ref_1","first-page":"1","article-title":"Osseointegrated implants in the treatment of the edentulous jaw.
