Periodontists and oral surgeons’ peri‐implantitis‐related education, knowledge, attitudes, and professional behavior: A national survey

Abstract

ObjectivesEach year, approximately 5 million dental implants are placed in the United States and one out of three patients is likely to experience peri‐implantitis (PI). The objectives were to compare the PI‐related education, knowledge, attitudes, and professional behavior of periodontists and oral maxillofacial surgeons (OMS), and to explore relationships between these constructs of interest.MethodsA total of 389 periodontists and 161 OMS responded to a web‐based survey. Descriptive and inferential statistical analyses (independent sample t‐tests, chi‐square tests, and correlational analyses) were conducted.ResultsOn average, periodontists reported a higher percentage of time spent in residency on implant surgery (21.02% vs. 7.27%; p < 0.001), better education about PI (5‐point scale with 1 = not at all well: means: 2.86 vs. 2.59; p < 0.001), and better knowledge of risk factors (4.07 vs. 3.86; p < 0.001) than OMS. Periodontists argued that oral hygiene‐related treatment (4.45 vs. 4.22; p = 0.001) and regeneration‐focused treatments such as guided tissue regeneration (3.62 vs. 3.20; p < 0.001) contributed more to successfully treating PI and used these treatments more in their practices (4.86 vs. 4.56; p < 0.001/3.06 vs. 2.68; p < 0.001) than OMS. They also considered PI as a more serious problem than OMS (4.55 vs. 3.80; p < 0.001). The better the respondents’ PI‐related knowledge was, the more they considered PI as a serious problem (r = 0.19; p < 0.001). The more cases they treated per month, the more they considered PI as a serious problem (r = 0.19; p < 0.001).ConclusionsThe results of the present study highlight the lack of standardization in the specialty training of periodontists and OMS. Best practice guidelines for the diagnosis and treatment of PI are needed to optimize graduate education about this important topic.
