Objective The objective of the analysis was to examine the association between sociodemographic and dental understanding and utilization characteristics and lower oral health literacy ( HL ) and knowledge. Methods The cross‐sectional Multicenter Oral Health Literacy Research Study ( MOHLRS ) recruited and interviewed 923 English‐speaking, initial care‐seeking adults. The questionnaire included participant sociodemographic characteristics, measures of the participant's understanding and utilization of dentistry, and two oral HL measures, the Rapid Estimate of Adult Literacy in Medicine and Dentistry ( REALM ‐D) and the Comprehensive Measure of Oral Health Knowledge ( CMOHK ), which were combined into a new composite HL and knowledge measure, the MOHLR ‐K. Results In adjusted multivariable analysis, persons who reported more understanding of dentist instructions had higher mean scores for all HL measures. Subjects reporting the highest level of understanding had greater scores by an average of 1.6 points for the MOHLR ‐K (95% CI : 0.85‐2.40, P <.01), 2.11 points for REALMD ‐20 (95% CI : 0.75‐3.48, P <.01) and 2.20 points for CMOHK (95% CI : 1.01‐3.40, P <.01) after controlling for demographic and other dental understanding and utilization factors. Persons who reported history of tooth decay had higher MOHLR ‐K scores by an average of about 0.77 points (95% CI : 0.49‐1.04, P <.01), higher REALMD ‐20 scores by 0.54 points (95% CI : 0.12‐0.95, P =.01) and higher CMOHK scores by 1.22 points (95% CI : 0.82‐1.63, P <.01) as compared to persons without tooth decay history after controlling for the other factors. Persons who had support all of the time for travel to the dentist had higher scores by an average of about 0.5 points for the MOHLR ‐K (95% CI : 0.04‐0.96, P =.03) and about 0.89 points for the REALMD ‐20 (95% CI : 0‐1.79, P =.05) as compared to subjects with no support after controlling for other factors. Report of periodontal history, financial challenges to delay a dental visit and dental utilization were not significantly associated with any of the HL measures once the other factors were adjusted for in the model. Conclusion The analysis confirmed that pronunciation of medical and dental terms may not fully reflect comprehension and revealed that understanding both patients’ sociodemographic and dental understanding and utilization factors, such as transportation to the dental office associated with lower oral HL and knowledge, could help the profession develop appropriate clear language programmes to improve access to dental care for vulnerable populations.
