Prescription of antibiotic prophylaxis in implant placement among Portuguese dentists: A web survey

Abstract

AbstractObjectivesThis study aims to assess whether antibiotic prophylaxis for dental implant placement is commonly used by dentists in Portugal.Materials and MethodsThis cross‐sectional survey study was based on a web survey with 22 questions divided into 5 parts. The 1st part focused on demographic details, work experience, and academic expertise, whereas the 2nd and 3rd parts were about the pre‐ and postoperative antibiotic prescriptions. The 4th and 5th parts focused on dentists' motivation for using/avoiding antibiotic prophylaxis and the use of a protocol, respectively. Data interpretation included descriptive analysis and statistical inference via cross‐tabling with chi‐square adjusted standardised for residual effects.ResultsOf the 204 valid surveys, at least one was received from every large Portuguese city which ensured the national coverage of the survey. Most respondents are not specialist dentists (72%). Sixty‐four percent of the respondents always use antibiotic prophylaxis, while 29% adopt it only when grafting materials are employed. Most respondents use both pre‐ and postoperative regimens (55%). Amoxicillin 875 mg + clavulanic acid 125 mg is the most prescribed antibiotic (57%). Finally, the risk reduction of postoperative infection is the most frequent justification for the use of antibiotic prophylaxis (60%).ConclusionsThe results highlight that most of the respondents do not follow the consensual international guidelines for prophylactic antibiotherapy in dental implant placement surgeries. This finding should serve as a rationale to increase the dissemination of those guidelines.
