The bidirectional relationship between periodontal disease and diabetes underscores opportunities for opportunistic screening within dental practice settings, yet dental hygienist engagement remains limited by attitudinal and knowledge barriers. 
Japanese investigators conducted a cross-sectional survey among 234 dental hygienists in the Kanto region from December 2023 through February 2024, analyzing 75 valid responses (32.1% response rate). The results were published in the Diabetes Epidemiology and Management. 
Self-administered questionnaires captured attitudes toward diabetes management and current screening practices including management status assessment, therapeutic regimen verification, and symptom evaluation. 
Training Gaps Limit Screening Implementation
Only 36% of dental hygienists reported prior diabetes management training, reflecting substantial educational deficits constraining screening integration into routine periodontal assessments. This knowledge-practice gap represents a modifiable barrier to medical-dental collaboration.
Willingness Drives Comprehensive Screening Adoption
Willingness to manage diabetes emerged as the dominant positive predictor across all screening domains, demonstrating substantial effect sizes: checking management status (β=0.34, 95% CI 0.28-1.41), therapeutic status verification (β=0.39, 95% CI 0.22-0.84), and symptom evaluation (β=0.30, 95% CI 0.12-0.72). These findings confirm positive attitudes as primary adoption drivers.
Knowledge Barriers Suppress Routine Assessment
Conversely, lack of knowledge and confidence exerted moderate negative association with management status checking (β=-0.33, 95% CI -0.94 to -0.17), underscoring educational interventions as priority targets. Clinical experience and diabetes education independently predicted symptom screening, reinforcing training value.
Integrated Training Enhances Primary Care Collaboration
Endodontists, periodontists, and endocrinologists gain evidence supporting structured dental hygienist education to expand diabetes case-finding within high-yield periodontal clinics. Brief screening protocols leveraging glucometer capillary testing or HbA1c point-of-care assessment facilitate immediate referral cascades. Positive attitude reinforcement through interprofessional workshops maximizes practice translation while addressing knowledge deficits systematically.
