In dentistry, a combination of soft and hard skills is crucial for successful practice and for achieving health care organization goals. However, dental schools face significant challenges in teaching and evaluating soft skills, including the subjective nature of assessment, variability in student engagement, and the lack of standardized curricula. The development of ethical and critical thinking skills is essential for students to balance competing interests in the profession while maintaining professionalism, such as dedication, accountability, competence, dependability, and respect for others. Health care professionals, including dentists, must cultivate soft skills to effectively guide and treat patients. This study aims to raise awareness of the importance of soft skills in dental education, specifically highlighting challenges in instruction and evaluation. Key conclusions include the need for a more structured approach to teaching soft skills, integrating them into the broader curriculum, and developing more objective assessment tools. By addressing these issues, dental education can better equip future dentists with the necessary skills for efficient patient care.</p>","PeriodicalId":12028,"journal":{"name":"European Journal of Dentistry","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142806523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hemorrhagic stroke, which primarily occurs within the brain tissue or in the subarachnoid space as a blood leak of ruptured vessels, is a sudden neurological impairment caused by vascular damage in the central nervous system, resulting in focal neurological deficits. Chronic periodontitis (CP) and hemorrhagic stroke may share common pathogenic features involving inflammation and immune system activation, prompting researchers to investigate their potential connection. The aim of the study is to systematically review the literature on the epidemiological association between CP and hemorrhagic stroke in adults. The study protocol adhered to the PRISMA 2020 guidelines, and the design followed the Cochrane methodology. A thorough literature search encompassing PubMed, Scopus, and Web of Science databases and a manual search and evaluation of gray literature was conducted.
