Integrating Oral Health and Primary Care in the Changing Health Care Landscape.

The bi-directional relationship among oral health and other systemic diseases and conditions provides a strong rationale for integration of oral health and primary care practice. Patient care services may be coordinated across different times, places, and professional disciplines to provide a team approach to care for overall health.

Comparing Well-Tested Health Literacy Measures for Oral Health: A Pilot Assessment.

There has been growing national concern over the low health literacy of Americans and, coinciding with this, a growing importance placed on measuring health literacy. Health literacy is the ability to access, understand, and use information to make health decisions. Health literacy in an oral health context means access to accurate information about oral health, understanding the risks of neglecting oral care, and calculating the chances of getting periodontal disease. This exploratory study compared the 3 most popular and well-tested health literacy measures in an oral health setting. Using a survey of dental patients from safety net dental clinics in two states, we explored differences and similarities between health literacy measures as they pertained to oral health perceptions and oral self-efficacy. Findings indicated that the three health literacy measures were not interchangeable and had differential effects on data collected, which suggested differential relationships with oral health perceptions and outcomes.

Los Angeles County dentists' opinions on discussing human papilloma virus-related oral health issues and recommending vaccine to patients.

Dentists are well-positioned to discuss oral health issues related to Human Papillomavirus (HPV) and recommend the HPV vaccine to their patients, mainly because the HPV virus causes oropharyngeal cancers.. We assessed Los Angeles (LA) County dentists' opinions on discussing HPV-related oral health issues and recommending the HPV vaccine to their patients. We tested if opinions differed between dentists whose primary patient population was only adults versus children and adults. We mailed a 19-item survey to 2000 randomly sampled LA County dentists for this cross-sectional study. The primary outcome variable was a summary opinion score of 7 opinion statements. We ran descriptive, bivariate comparisons and adjusted linear regression models. Overall, 261 dentists completed the survey. A majority (58.5%) worried they would lose patients if they recommended the vaccine; 49% thought dentists were not appropriate to educate, counsel, or advise on HPV-related issues; 42% were concerned about the safety of the vaccine; and 40% did not feel comfortable recommending the vaccine. The mean summary opinion score was 21.4 ± 5.4 for the total sample. Regression analysis showed no differences in opinions between dentists whose primary patient population was only adults versus children and adults (Coefficient = 0.146, p = 0.83). Overall, the responding dentists were not very favorable about discussing oral health-related HPV issues and recommending the HPV vaccine to their patients. Additionally, the overall opinions were similar between dentists whose primary patient population was only adults versus children and adults.

Impact of cone-beam computed tomography on orthodontic diagnosis and treatment planning.

INTRODUCTION: In this study, we measured the impact of cone-beam computed tomography (CBCT) on orthodontic diagnosis and treatment planning. METHODS: Participant orthodontists shown traditional orthodontic records for 6 patients were asked to provide a diagnostic problem list, a hypothetical treatment plan, and a clinical certainty. They then evaluated a CBCT scan for each patient and noted any changes, confirmations, or enhancements to their diagnosis and treatment plan. RESULTS: The number of diagnosis and treatment plan changes varied widely by patient characteristics. The most frequently reported diagnosis and treatment plan changes occurred in patients with unerupted teeth, severe root resorption, or severe skeletal discrepancies. We found no benefit in terms of changes in treatment plan for patients when the reason for obtaining a CBCT scan was to examine for abnormalities of the temporomandibular joint or airway, or crowding. Orthodontic participants who own CBCT machines or use CBCT scans frequently in practice reported significantly more diagnosis and treatment plan changes and greater confidence after viewing the CBCT scans during the study. CONCLUSIONS: The results of this study support obtaining a CBCT scan before orthodontic diagnosis and treatment planning when a patient has an unerupted tooth with delayed eruption or a questionable location, severe root resorption as diagnosed with a periapical or panoramic radiograph, or a severe skeletal discrepancy. We propose that CBCT scans should be ordered only when there is clear, specific, individual clinical justification.

Dental care utilization among developmentally disabled adolescents experiencing difficulty with decayed teeth: A population-level study.

AIMS: To determine if adolescents with developmental disabilities (DDs) who experienced difficulty with dental caries differed by dental visits in the past 12 months and receipt of preventive services (fluoride treatment and dental sealants) during those visits compared to adolescents with no DDs or difficulty with dental caries. METHODS AND RESULTS: A cross-sectional study was conducted using data of 91 196 adolescents aged 10-17 years from the 2016-2020 National Survey of Children's Health. Descriptive and bivariate statistics and multivariable regression models were conducted. We derived the odds ratio for visiting a dental office (OR: 0.76, 95% CI: 0.57-1.03, p = .07), receiving fluoride treatments (OR: 1.20, 95% CI: 1.01-1.43, p = .04), and dental sealants (OR: 1.44, 95% CI: 1.19-1.75, p < .001) for DD adolescents who experienced difficulty with dental caries compared to adolescents with no DDs or difficulty with dental caries. CONCLUSIONS: DD adolescents who experienced difficulty with dental caries were more likely to receive fluoride treatments and sealants during dental visits but were equally likely to have a dental visit in the past 12 months than adolescents with no DDs or difficulty with dental caries.

Association between oral health knowledge, perceived oral health related quality of life, perceived oral health status and emergency department and/or urgent care visit: Results from the multi-site oral health literacy study.

OBJECTIVES: To assess the link between oral health knowledge (OHK), self-perceived oral health, and emergency room (ER)/urgent care utilization for a dental problem. METHODS: Data were analyzed from a convenience sample of 790 adult participants who presented to two US dental schools and completed an interviewer-administered survey. Key independent variables were OHK assessed with the Comprehensive Measure of Oral Health Knowledge (CMOHK) instrument, self-perceived oral health status and quality of life determined using the General Oral Health Assessment Index (GOHAI) scores. The dependent variable was ER and/or urgent care utilization for a dental problem. Select sociodemographic variables such as age and gender were adjusted for in logistic regression models using SAS. RESULTS: 15.7% of the participants had ever visited an ER and/or urgent care for a dental problem. CMOHK scores were not significantly associated with visits to the ER and/or urgent care. In adjusted analysis, participants with unfavorable GOHAI scores were about three times as likely to have had an ER and/or urgent care visit (OR = 2.60, 95% CI: 1.66-4.09). Similarly, participants who were unsatisfied with their oral health were about twice as likely to have had an ER and/or urgent care visit (OR = 1.91, 95% CI: 1.21-3.00) as compared to those satisfied with their oral health status. CONCLUSION: Individuals unsatisfied with their oral health and those with unfavorable perceived oral health related quality of life could benefit from a greater awareness of dental service availability and extended hours including weekend hours at public dental clinics.

A national sample of developmentally disabled adolescents with obesity and their utilization of preventive dental care services.

Background: Previous literature indicates that adolescents with developmental disabilities and obesity may have more oral health complications than healthy adolescents. However, dental care utilization among adolescents with developmental disabilities (DDs) and obesity is unclear. We investigated the differences in the utilization of preventive dental services between this high-risk group of adolescents and those with no DDs or obesity. Methods: Parent-reported data of adolescents 10-17 years (n = 68,942) from the 2016 to 2019 National Survey of Children's Health was used. In addition to descriptive and bivariate statistics, we ran three multiple logistic regression models guided by Andersen's Behavioral Model of Health Services Use, predicting the use of dental cleanings, fluoride treatments, and dental sealants. Results: Among adolescents with DDs and obesity, dental cleanings, fluoride treatments, and dental sealant utilization prevalence were 76%, 48%, and 21%, respectively. In comparison, adolescents with no DDs or obesity had a prevalence of 83%, 50%, and 19%, respectively. Multiple logistic regression analysis showed that adolescents with DDs and obesity did not significantly differ in their receipt of dental cleanings (p = .07), fluoride treatments (p = .55), and dental sealants (p = .23) compared to those with neither DDs nor obesity. Adolescents with DDs but no obesity were 22% and 30% more likely to receive fluoride treatments (p < .0001) and dental sealants (p < .0001), respectively. Conclusions: Fewer than half of adolescents with DDs and obesity utilized fluoride treatments, and less than one quarter utilized dental sealants but used all three preventive services at the same rate as those with no DDs or obesity. Implications: This study identified no differences in preventive dental care services utilization in adolescents with developmental disabilities (DDs) and obesity compared to those without DDs and obesity. However, the utilization of preventive dental services in this population is influenced by the federal poverty level and family background.

Hospital emergency department visits made by developmentally disabled adolescents with oral complications.

Purpose: We used Andersen's Behavioral Model in a cross-sectional study to determine the factors associated with utilization of the emergency department (ED), controlling for whether an adolescent has a developmental disability (DD) and one or more oral complications (toothaches, decayed teeth, bleeding gums, eating or swallowing problems). Methods: Data from the 2016-2019 National Survey of Children's Health (NSCH) was used for this secondary data analysis study. We used frequencies and percentages to describe the sample characteristics. Chi-square tests were used for bivariate analyses. Multivariable logistic regression modeling was conducted to predict ED visits by adolescents aged 10-17 controlling for predisposing, enabling, and need variables. Results: The sample consisted of 68,942 adolescents who were primarily male, non-Hispanic White, and born in the U.S. Parents reported that 69% of the adolescents had neither a DD nor an oral complication; 10% had no DD but experienced one or more oral complication; 16% had a DD but no oral complication; and 5% had both DDs and one or more oral complication. Adolescents with both a DD and an oral complication reported the highest level of ED visits at 33%, compared to 14% of adolescents with neither DD nor oral complication. Regression analysis showed that adolescents with a DD and oral complication (OR: 2.0, 95% CI: 1.64-2.54, p < 0.0001), and those with DDs but no oral complications (OR: 1.45, 95% CI: 1.25-1.68, p < 0.0001) were at higher odds of having an ED visit compared to those with neither a DD nor an oral complication. Not having a Medical Home increased the likelihood of ED visits by 14% (p = 0.02). Those with private insurance (OR: 0.63, 95% CI: 0.53-0.75, p < 0.0001) and those from a family where the highest level of education was some college and above (OR: 0.85, 95% CI: 0.73-0.98, p = 0.03) were less likely than their counterparts to have had an ED visit. Conclusion: Adolescents with DDs and oral complications utilize ED visits more frequently than those with neither DDs nor oral complications. Integrating the dental and medical health systems and incorporating concepts of a Patient-Centered Medical Home could improve overall health care and reduce ED visits for adolescents.

Oral Health in America: Implications for dental practice.

BACKGROUND: Important, but insufficient, gains have been achieved in access to and delivery of oral health care since the 2000 US surgeon general's report on oral health in America. Access to care has increased for children and young adults, but considerable work remains to meet the oral health care needs of all people equitably. The National Institutes of Health report, Oral Health in America: Advances and Challenges, reviews the state of the US oral health care system, achievements made since 2000, and remaining challenges. In this article, the authors highlight key advances and continuing challenges regarding oral health status, access to care and the delivery system, integration of oral and systemic health, financing of oral health care, and the oral health workforce. RESULTS: Public insurance coverage has increased since 2000 but remains limited for many low-income, minority, and older adult populations. The oral health care workforce has expanded to include new dental specialties and allied professional models, increasing access to health promotion and preventive services. Practice gains made by women and Asian Americans have not extended to other minority demographic groups. Oral health integration models are improving access to and delivery of patient-centered care for some vulnerable populations. CONCLUSIONS AND PRACTICAL IMPLICATIONS: Coordinated policies and additional resources are needed to further improve access to care, develop dental insurance programs that reduce out-of-pocket costs to lower-income adults, and improve the integration of oral and medical health care delivery targeting a common set of patient-centered outcomes. Dental care professionals need to fully participate in meaningful and system-wide change to meet the needs of the population equitably.

Assessing oral health content in nondental professional association websites.

OBJECTIVES: Determine the prevalence and type of oral health (OH) content among nondental health professional associations' websites. METHODS: Fifty-nine organizations were selected from three lists of health professional associations and categorized as physician-, nurse- and other healthcare-related professions. Eight dental search terms were used on searchable websites. Six types of OH information were collected. Websites were assessed for any OH content and comparisons made. Frequencies, chi-square, and Fisher extract test statistics were calculated. RESULTS: Thirty-five (59 percent) of websites had any OH information content. Twenty (34 percent) had OH authored content, 10-19 percent had OH webpages, interest groups, or initiatives, CE courses or webinars, or curriculum information. The term "oral hygiene" gave the greatest yield and "dentistry" the least. No significant differences in existence of "Any OH content" was found between each organization type versus others. CONCLUSION: Many nondental professional associations could increase OH website content and education with assistance from dental organizations.

Predictors of risk tolerance among oral surgery patients.

PURPOSE: This study attempts to provide insight on how the treatment preference for a mandible fracture and treatment received and its consequences are related to the patient's risk tolerance, as measured by the Standard Gamble (SG). PATIENTS AND METHODS: Data from a prospective cohort study of 203 subjects receiving treatment at the former King/Drew Medical Center in Los Angeles, CA, for either a mandible fracture (n = 98) or third molar removal (n = 105) were examined. Subjects were interviewed at 4 time points: on admission to the medical center and at 3 monthly follow-up visits. Risk tolerance for hypothetical treatment scenarios is measured by use of the SG, a health-value utility measure assessing the tradeoff between good outcomes and serious complications associated with treatment. Separate regression analyses with subsets of predictors (sociodemographic, psychosocial health, and clinical characteristics) were conducted and then synthesized by use of the significant predictors in separate analyses. RESULTS: For fracture subjects, there was a noticeable rise in the SG reports from admission to the 1-month follow-up. Their greater risk tolerance was associated with being older, receiving surgery, having a lower post-traumatic stress disorder score, and having a swollen jaw or face. For third molar subjects, SG did not change substantively over the course of the study. Predictors of greater risk tolerance for third molar subjects included the jaw or face being swollen and having to use less pain medication. CONCLUSIONS: Findings from this study show a preference for less invasive treatment, with the majority of both groups preferring wiring, and support the theory that treatment choices differ between subjects with different health states. Factors associated with risk tolerance include the patient's age, treatment received, psychosocial health state, experience with previous treatment, and value for oral health quality of life.

Screening for oral health literacy in an urban dental clinic.

OBJECTIVE: Studies show that the average person fails to understand and use health care related materials to their full potential. The goal of this study was to evaluate a health literacy instrument based on the Rapid Estimate of Adult Literacy in Medicine (REALM) that incorporates dental and medical terms into one 84-item Rapid Estimate of Adult Literacy in Medicine and Dentistry (REALM-D) measure and determine its association with patient characteristics of a culturally diverse dental clinic population. METHODS: An 84-item dental/medical health literacy word list and a 48-item health beliefs and attitudes survey was provided to a sample of 200 adult patients seeking treatment for the first time at an oral diagnosis clinic located in a large urban medical center in Los Angeles, California. RESULTS: Of the total sample, 154 participants read all of list 1 correctly, 141 read list 2 correctly, and only 38 read list 3 correctly. Nonwhite participants had significantly lower REALM-D scores at each level of difficulty as well as the total scale score compared to white participants. Participants who reported English as not their main language had significantly lower REALM-D scores. REALM-D scores also varied significantly by level of education among participants where as level of education increased, oral health literacy increased. At a bivariate level, race, education, and English as a main language remain predictive of health literacy in a regression model. An interaction between education and English as a main language was significant. CONCLUSIONS: The REALM-D is an effective instrument for use by medical and dental clinicians in detecting differences among people of different backgrounds and for whom English was not their primary language.

Predictors of treatment preference for mandibular fracture.

BACKGROUND: Patient treatment preferences do not necessarily remain stable over time. OBJECTIVE: This study focuses on predictors of patient treatment choice and on the extent to which patients are willing to take risks by choosing surgical versus nonsurgical treatment for mandibular fracture. METHODS: Surveys of African-American and Hispanic adults receiving treatment at King/Drew Medical Center for either a mandibular fracture (n = 98) or third-molar removal (n = 105) were used to investigate patterns of patient preference over the course of a 4-month study period using generalized estimating equations controlling for age, gender, income, and fracture versus third-molar patient. The study examined the effects of symptom rating and a"standard gamble" measure reflecting a patient's willingness to accept scarring or nerve damage. This analysis is based on 169 patients who participated in four waves of data collection. RESULTS: The most salient predictor of patient treatment was the standard gamble measure at 1-month follow-up. Subjects with higher risk tolerance were more likely to select surgery versus jaw wiring. A higher likelihood of choosing surgery was associated with higher income and greater symptom severity. Fracture patients were more likely to select surgery compared with third-molar patients. CONCLUSIONS: The significance of symptom severity 1-month post-surgery raises an important issue regarding the healing process. Moreover, the significance of standard gamble as a predictor of treatment choice for mandibular fracture should encourage other researchers to use this measure of willingness to accept risk when studying acute conditions such as jaw fracture.

The Evolving Role of Health Literacy in Improving Oral Health.

This chapter provides a review of the evolution of oral health literacy including its impact on oral health outcomes, the current status of oral health literacy initiatives and future research needs. Using the Healthy People 2010 definition, the chapter describes opportunities needed to improve oral health literacy among health providers as well as individuals/patients, communities and policy-makers. Studies of the two most prevalent dental diseasesâATdental caries and periodontal diseases - reveal that increasing the oral health literacy of the public and health care providers can play a major role in reducing these diseases. Increasing oral health literacy by creating access to accurate knowledge and supporting use of science-based preventive measures is essential. A major part of the chapter describes oral health literacy's influence in the integration of dental and medical care. The chapter provides an extensive list of research needed to further our understanding of the impact of oral health literacy on health disparities and the health of the population.

Predictors of depressive symptoms following mandibular fracture repair.

PURPOSE: This study sought to identify sociodemographic, psychosocial, and clinical factors associated with increased postsurgery depressive symptoms among inner-city minority patients recovering from a mandibular fracture. PATIENTS AND METHODS: Surveys of African American and Hispanic adults receiving treatment at King/Drew Medical Center for a mandible fracture (n=98) are used to identify factors associated with increased postsurgery depressive symptoms. Using correlation coefficients and t tests, bivariate relationships between patient characteristics and depressive symptoms at first follow-up were examined. Multiple regression analysis was used, predicting depressive symptoms at 1 month postadmission by entering covariates that were found to be significant at the bivariate level. RESULTS: Consistent with the etiology of maxillofacial trauma, the majority of study participants were male (88%), unmarried (92%), unemployed (57%), and experienced some type of interpersonal violence resulting in their broken jaw (77%). Patient characteristics significantly associated with depressive symptoms at first follow-up included age (r=0.26, P= .011), symptoms of post-traumatic stress (r=0.31, P= .003), prior dental problems (r=0.24, P= .022), current pain (r=0.38, P<0.001), and oral health problems during healing (GOHAI) (r= 0.34, P= .001). Two of the 5 significant covariates (pain and GOHAI) remained significant at the multivariate level (adjusted R(2)=0.33). CONCLUSION: Findings from this study show that depressive symptoms increase immediately after oral surgery for jaw fracture. This increase is associated with pain and quality of life during recovery.

Do the benefits of rigid internal fixation of mandible fractures justify the added costs? Results from a randomized controlled trial.

PURPOSE: Owing to its putative advantages over conventional maxillomandibular fixation (MMF), open-reduction and rigid internal fixation (ORIF) is used frequently to treat mandible fractures, particularly in noncompliant patients. The resource-intensive nature of ORIF, the large variation in its use, and the lack of systematic studies substantiating ORIF attributed benefits compel a randomized controlled investigation comparing ORIF to MMF treatment. The objective of this study was to determine whether ORIF provides better clinical and functional outcomes than MMF in noncomplying type of patients with a similar range of mandible fracture severity. PATIENTS AND METHODS: From a total of 336 patients who sought treatment for mandible fractures, 142 patients with moderately severe mandible fractures were assigned randomly to receive MMF or ORIF and followed prospectively for 12 months. A variety of clinician and patient-reported measures were used to assess outcomes at the 1, 6, and 12 months follow-up visits. These measures included clinician-reported number of surgical complications, patient-reported number of complaints, as well as cumulative costs of treatment. Pain intensity was measured on a 10-point scale and the 12-item General Oral Health Assessment Index was used to assess the patients' oral health-related quality of life. Because the protocol allowed clinical judgment to overrule the randomly assigned treatment, outcomes were compared on an "intent-to-treat" basis as well as in terms of actual treatment received. RESULTS: The sociodemographic and clinical characteristics of the injury did not differ among the 2 groups. On an intent-to-treat basis, the difference in complication rates was not significant but favored MMF; 8.1% of patients developed complications with MMF versus 12.5% with ORIF. Differences in the rate of patient complaints were not significant on an intent-to-treat basis, but a significant between-group difference (P = .012) favoring MMF was noted on an as-treated basis at the 1 month recall, with 40% of ORIF patients reporting greater than 1 complaint versus 18.8% of MMF patients. No significant differences were detected between the 2 treatment groups at any time point with respect to oral health-related quality of life reflected by the General Oral Health Assessment Index scores. In-patient days and total costs did not differ significantly on an intent-to-treat basis, but on an as-treated basis, patients treated with MMF had fewer in-patient days on average (1.64 vs 5.50 for ORIF) and lower average costs of treatment ($7,206 vs $26,089 for ORIF). In the intent-to-treat analyses, patients receiving MMF treatment had significantly lower (P = .05) pain scores at the 12-month recall (mean = 0.58, SE = 0.30) compared with patients assigned to ORIF (mean = 1.78, SE = 0.52). CONCLUSION: Our study did not show a clear overall benefit of the resource-intensive ORIF over conventional MMF treatment in the management of moderately severe mandible fractures in at-risk patients; our data instead suggest some cost as well as oral health quality-of-life advantages for the use of MMF in this patient population.

Reforming dental education: faculty members' perceptions on the continuation of pipeline program changes.

In 2002-03 the Robert Wood Johnson Foundation (RWJF) established the Pipeline, Profession, and Practice: Community-Based Dental Education program to change dental education in the United States. In partnership with The California Endowment, the RWJF awarded grants to fifteen U.S. dental schools that would support them in efforts to recruit more underrepresented minority/low-income (URM/LI) students, add cultural competence training, and increase extramural rotations to sixty days. As the program evaluator, the University of California, Los Angeles, School of Public Health (UCLA-SPH) conducted a survey of dental faculty in 2006 related to the goals of the Pipeline program. In this article, we report faculty perceptions pertaining to the extramural rotations and URM/LI recruitment. The survey was conducted in fourteen U.S. dental schools that received Pipeline grants and had an overall response rate of 60 percent (n=1,027) from the 1,713 faculty members who received the survey. A majority (57 percent) of faculty members strongly agreed that extramural rotations should continue as an integral part of students' education; 51 percent felt the same about the continuation of URM/LI recruitment programs. Multivariate logistic regression analyses revealed that faculty type, perception of extramural rotations being a positive experience, increased student productivity, and school culture were significant determinants of support for continuation of the extramural rotation programs. Determinants of support for continuation of the URM/LI recruitment programs were faculty type, perception of URM/LI recruitment effectiveness, perception of students from diverse backgrounds improving educational experience, and having a school mission statement that supports URM/LI recruitment. Pipeline schools should ensure that their extramural faculty remain key players in the Pipeline programs, widely publicize the programs' successes, and develop a service-oriented culture in order to build and sustain faculty perceptions that these programs should continue as integral parts of the schools' educational mission.

Bridging the dental-medical divide: Case studies integrating oral health care and primary health care.

BACKGROUND: The National Academies of Sciences, Engineering, and Medicine commissioned an environmental scan describing the status of health care integration of oral health and primary care services. METHODS: The authors conducted an environmental scan of US integration activities with publications from January 2000 through August 2017. They categorized services as preventive oral health services (POHS) provided by medical care providers, POHS provided by dental providers in nondental settings, preventive health services provided by dental providers, or care coordination using dedicated personnel and technology. The authors chose 4 programs as case studies and interviewed key personnel in each program. One case study illustrates each category of integrated services; additional examples describe category variation. RESULTS: The case study involving Into the Mouth of Babes illustrates medical professionals delivering POHS to children. The case study involving Grace Health presents dental hygienists embedded in the obstetrics-gynecology clinic to provide oral screening, prophylaxis, and education to pregnant women. At HealthPartners, medical care providers refer patients with diabetes to dentists and waive copays for periodontal care. The InterCommunity Health Network Coordinated Care Organization uses dedicated patient coordinators, technology, and coordinated payment and referral mechanisms to facilitate care. CONCLUSIONS: Integration of dental and medical care increased access to and coordination of patient care by means of offering health care services traditionally provided by the other profession. PRACTICAL IMPLICATIONS: Integration models demonstrate the incorporation of POHS by primary care professionals, the embedding of dental professionals into primary care clinics, and the incorporation of care coordination to increase the delivery of oral health care. Similarly, dentists identify and refer patients with medical needs or preventive gaps to medical homes.

Baseline characteristics and treatment preferences of oral surgery patients.

PURPOSE: Patient preferences for treatment choices may depend on patient characteristics. Using standard gamble (SG) and willingness to pay (WTP), this study compares preferences for treatment of mandibular fracture among patients in a low-income urban area. PATIENTS AND METHODS: Surveys of African-American and Hispanic adults receiving treatment at King/Drew Medical Center for either mandibular fracture (n = 98) or third molar removal (n = 105) were used to investigate differences in patient characteristics across treatment groups (third molar vs fracture) and treatment preference (wiring vs surgery). RESULTS: The fracture patients were willing to pay more to restore function without scarring or nerve damage than were the third molar patients. Patients who chose surgery were willing to accept a greater risk of possible nerve damage or scarring than those who chose wiring. Among 15 potential predictors of SG and WTP studied in 4 subgroups defined by actual treatment and treatment preference, significant predictors varied, with associations for education and clinical experience for SG and associations with income and psychosocial predictors for WTP. CONCLUSIONS: SG and WTP capture different domains of health values in patients. There is considerable heterogeneity in relationships among patient characteristics and patient preferences across subgroups defined by actual treatment and treatment preferences.

The value of a combined word recognition and knowledge measure to understand characteristics of our patients' oral health literacy.

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.
