Periodontitis vaccine decreases local prostaglandin E2 levels in a primate model.

Interleukin-1beta, tumor necrosis factor alpha, prostaglandin E2 (PGE2), and Porphyromonas gingivalis-specific immunoglobulin G levels in gingival crevicular fluid were measured in primates immunized with a P. gingivalis vaccine followed by ligature-induced periodontitis. Only PGE2 levels were dramatically suppressed (P < 0.0001) in immunized animals versus controls. A significant correlation (P < 0.027) was also found between PGE2 levels and decreased bone loss scores. This study presents the first evidence of a potential mechanism involved in periodontitis vaccine-induced suppression of bone loss in a nonhuman primate model and offers insight into the role of PGE2 in periodontal destruction.

The impact of ethnicity, gender, and marital status on periodontal and systemic health of older subjects in the Trials to Enhance Elders' Teeth and Oral Health (TEETH).

BACKGROUND: Few studies have examined the association between periodontitis risk, gender, and marital status in older adults. The purpose of this study was to assess if the oral health status of older subjects could be explained by differences in: 1) marital status; 2) gender; and 3) ethnicity. METHODS: Clinical and radiographic periodontal oral conditions were studied in 701 older subjects from the TEETH clinical trial. Medical conditions as well as ethnic and marital status and smoking habits were considered. RESULTS: A total of 89 married couples were identified; 40.7% of these were of European descent and 48.1% of Chinese descent. The mean age was 67.7 years (SD +/- 4.7). The men were older than the women (mean difference: 1.5 years, SD +/- 4.6, 95% confidence interval [CI]: 0.5 to 2.5, P<0.01). No significant differences in periodontal conditions were found between spouses or by marital status. Chinese descent was associated with a higher risk for periodontitis, regardless of marital status (odds ratio: 1.5, 95% CI: 1.05 to 2.04, P<0.03). CONCLUSIONS: 1) Married couples have similar social habits, similar oral health perceptions, and similar patterns of periodontal disease. 2) Dental studies including married couples do not bias data for married subjects as such. 3) Marital status has a limited impact on periodontal health but may have a greater impact on several systemic conditions, especially in widowed, divorced, or never married women. 4) Older Chinese subjects perceive themselves as being at lower risk for periodontitis but have more objective signs of periodontitis than older subjects of European descent.

Chronic periodontitis, a significant relationship with acute myocardial infarction.

BACKGROUND: Chronic periodontitis (CP) has been associated with cardiovascular diseases. The study purposes were to identify the odds of acute myocardial infarction (AMI) and CP defined at different thresholds. METHODS AND RESULTS: We studied 80 subjects with clinically confirmed AMI and 80 matched control subjects with no evidence of cardiovascular disease all receiving a comprehensive periodontal examination. Statistical analysis demonstrated a difference in the proportion of sites with a periodontal probing depth >/=6.0mm (2.7% for non-AMI and 12.1% for AMI group, 95% CI: -2.8 to 0.01, P<0.05) but no difference in the extent of gingival bleeding was found between groups. The odds ratio of having AMI and periodontitis varied between 9.2:1 to 14.1:1 with the greatest odds ratio if bone loss exceeded 4mm at >/=50% of the teeth (OR: 14.1:1, 95% CI: 5.5 to 28.2, P<0.0001). The odds ratio remained significant also when only non-smokers were considered (51 subjects) (OR: 7.0:1, 95% CI: 2.0 to 24.3, P<0.01). CONCLUSIONS: Our findings suggest that patients who at routine dental visits demonstrate evidence of bone loss around several teeth can predictably be identified as being at risk for future AMI. Such subjects should be referred for medical and periodontal examinations and treatments.

Locally delivered minocycline microspheres for the treatment of periodontitis in smokers.

AIM: The aim of the present analysis of a larger phase 3 clinical trial was to evaluate the efficacy of 1 mg minocycline hydrochloride microencapsulated in 3 mg of resorbable polymer, subgingivally administered as an adjunct to scaling and root planing (SRP) in smokers with chronic periodontitis. MATERIAL AND METHODS: Two hundred and seventy-one patients who smoked were randomized to one of three treatment groups: (1) SRP alone, (2) SRP plus vehicle (polymer without minocycline) or (3) SRP plus minocycline microspheres. Full mouth SRP was performed for all groups at baseline, and vehicle or minocycline microspheres were administered to the appropriate patients at all periodontal pockets > or =5 mm at baseline, 3 and 6 months. Efficacy was evaluated over 9 months. RESULTS: Significantly greater pocket depth reductions with SRP plus adjunctive minocycline microsphere treatment were observed at 1, 6 and 9 months (p<0.05) versus control treatments. At 9 months, smokers treated with SRP plus minocycline microspheres exhibited a pocket depth reduction of 1.19 mm from baseline, as compared to 0.90 mm for smokers treated with SRP alone. The efficacy of adjunctive minocycline microspheres was consistent among all tested smoking subcohorts, including those based on gender, age and smoking exposures. CONCLUSION: These data indicate that treatment with SRP plus locally delivered minocycline microspheres is more effective than SRP alone in reducing pocket depths in smokers with periodontitis.

Comparison between panoramic and intra-oral radiographs for the assessment of alveolar bone levels in a periodontal maintenance population.

BACKGROUND: Information about the agreement between intra-oral (I-O) and panoramic (OPG) radiographs is limited. AIMS: : (1) To assess the agreement between I-Os and OPGs for direct measurements of the distance between the cemento-enamel junction (CEJ) and the alveolar bone level (BL) as well as the proportional values in relation to the root length (CEJ-BL/root length), and (2) to explore the symmetry between the left- and right-side measurements. MATERIAL AND METHODS: I-Os and OPGs were studied in 292 periodontal maintenance subjects (mean age 55.5 years, SD+/-12.6) with on average 22.4 teeth (SD+/-4.1 range: 6-28). The images were measured using a PC software program. Site-based I-O and OPG values for CEJ-BL as well as CEJ-BL/root length were compared. OPG values of CEJ-BL/root length values between the left and right sides were also studied. RESULTS: A total of 11,395 linear distances (CEJ-BL plus CEJ-apex) from the I-Os and 21,462 linear distances from the OPGs were measured. The intra-class correlation coefficients (ICCs) between sets of readings of CEJ-BL varied between 0.80 and 0.89 (p<0.001), with the best agreement for tooth 22 (ICC: 0.89; 95% CI: 0.83-0.92). The ICCs for CEJ-BL/root length varied between 0.54 and 0.92. Mean differences between I-O and OPG values were in the 0.00-0.04 mm range for the CEJ-BL/root length comparisons. The maxillary anterior sextant demonstrated a 1.4 x enlargement by OPG for the CEJ-BL/root length comparisons. No distortions were observed for mandibular sextants. Left- and right-side symmetry of periodontal bone loss was demonstrated. ICC varied between 0.79 (95.00% CI: 0.71-0.84, p<0.01) and 0.53 (95.00% CI: 0.36-0.65, p< 0.01). CONCLUSIONS: I-O and OPG radiograph readings are in great agreement. Alveolar bone loss appeared to have a symmetrical distribution pattern. Hence for periodontal assessments, OPG radiographic readings may, at least in part, substitute for full-mouth periapical radiographic evaluation.

Perceived risk of deteriorating periodontal conditions.

BACKGROUND: Interpretation of risk for periodontitis is critical for treatment planning. How periodontists assess risk for periodontitis is unclear. PURPOSE: To study (1) what factors periodontists use when assessing the risks for worsening periodontal conditions anticipating that no treatment would be provided, and (2) if risk assessment is consistent and independent of specialty background training. MATERIAL AND METHODS: Medical history, clinical dental data, full-mouth intra-oral radiographs, and slide pictures were obtained from each of 51 subjects, and the information was provided to 23 examiners. RESULTS: The mean age of the study subjects was 51.5 years (SD +/- 17.7, range 23-81), with 28 women included. In 10 of the subjects, only gingivitis was identified, while 22 subjects had advanced chronic periodontitis. Risk scores assigned for 2 and 4 years differed significantly between European- and US-trained periodontists (p < 0.001) and between graduate students in training and periodontists from either the US or Europe (p < 0.01) (Wilcoxon n-pair test), with European periodontists scoring the lowest risks. Risk scores were correlated between groups (p < 0.01 with rho range 0.82-0.89) (Spearman's rank correlation). The best-fit model (r2 = 0.86) to assess perceived risk for worsening periodontal conditions based on data from all examiners combined included the following variables: (1) overall horizontal alveolar bone loss (p < 0.000), (2) age-adjusted proportional radiographic bone height score for the worst site (p < 0.000), and (3) proportion of pocket probing depths > or = 6.0 mm. CONCLUSIONS: Differences exist on the scale of risk values based on specialty training. Consistency in scoring patterns exists. The examiners based their assigned risk scores almost exclusively on measures of existing disease severity, including radiographic bone loss and numbers of periodontal pockets > or = 6.0 mm, and excluding most known risk factors such as smoking, diabetes, and poor oral hygiene.

Signs of carotid calcification from dental panoramic radiographs are in agreement with Doppler sonography results.

BACKGROUND: Duplex ultrasonography (DS) is a frequently used noninvasive method for assessing carotid artery stenosis. The level of agreement between panoramic radiographs (PMX) findings of radiopacities in the area of C3-C4 and DS results has not been established. AIMS: (1) to examine the level of agreement between DS results and PMX signs of carotid calcification and (2) to evaluate the association between periodontitis and DS results. MATERIAL AND METHODS: Eighty-three subjects who had received a DS assessment at the University of Washington Medical Center within 36 months volunteered for a periodontal examination, including assessments of probing pocket depth (PPD), attachment level (PAL), evidence of bleeding on probing and bone loss from PMX. Two examiners independently analyzed the radiographs for evidence of carotid calcifications. The distance between the cemento-enamel junction (CEJ) to bone level (BL) CEJ-BL was used to assess alveolar bone loss as a criteria for periodontitis. RESULTS: Twenty-nine subjects (34.9%) presented with positive DS readings. The Mantel-Haentszel common odds ratio estimate for a positive DS score and periodontitis (> 30% of teeth with distance CEJ-BL > or = 4.0 mm) was 38.4 (95% CI: 10.6-138.7, p < 0.0001). For nonsmokers only (n = 72) the odds ratio was 43.0 (95% CI: 16.7-1178.0, p < 0.0001). Evidence of bleeding on probing was 16% of sites both in the DS-positive and -negative subjects. Subjects with a positive DS result had significantly more teeth with clinical evidence of attachment loss > or = 5.0 mm (p < 0.001). The odds ratio of having periodontitis (CEJ-BL > or = 4.0 mm at > or = 30% of the teeth) and medical records confirmed diagnosis of either a stroke or an infarct or both was 7.8 (95% CI: 2.6-23.8, p < 0.001). CONCLUSIONS: Subjects with positive DS readings of the carotid arteries due to calcified arterial plaque are accurately detected by means of conventional PMX. The likelihood of being DS positive and having radiographic evidence of periodontitis is high. A dose-response relationship between the extent of carotid calcification and severity of periodontitis was demonstrated, supporting the hypothesis of an association between periodontitis and cardiovascular diseases.

Assessing periodontal disease risk: a comparison of clinicians' assessment versus a computerized tool.

BACKGROUND: The authors conducted a study to compare risk scores assigned by subjective expert clinician opinion with quantitative scores generated for the same subjects using the Periodontal Risk Calculator, or PRC. METHODS: The authors assembled a group of 107 subjects and performed standard periodontal examinations. The authors entered the resulting information into the PRC and calculated risk scores for two and four years, assuming no treatment would be performed. Using the same subject records, three groups of expert clinicians assigned risk scores for years 2 and 4. The authors analyzed the data to reveal the extent of interevaluator variation and the level of agreement between expert clinician scores and PRC scores. RESULTS: The extent of variation among scores assigned by individual expert clinicians was greater than the authors had expected. Expert clinicians consistently assigned more subjects to PRC risk group 2 and fewer to risk group 5 than did the PRC. The authors observed very high heterogeneity in the risk scores expert clinicians assigned to patients in each of the PRC-assigned groups. Thus, expert clinicians varied greatly in evaluating risk and, relative to the PRC, they appeared to underestimate periodontitis risk, especially for high-risk patients. CONCLUSIONS AND PRACTICE IMPLICATIONS: The authors' observations suggest that use of risk scores generated for individual patients by subjective expert clinician opinion about risk in periodontal clinical decision making could result in the misapplication of treatment for some patients and support the use of an objective tool such as the PRC. Use of the PRC over time may be expected to result in more uniform and accurate periodontal clinical decision making, improved oral health, reduction in the need for complex therapy and reduction in health care costs.

Influence of interleukin-1 gene polymorphism on the outcome of supportive periodontal therapy explored by a multi-factorial periodontal risk assessment model (PRA).

BACKGROUND: Multi-factorial risk models have been proposed to enhance the ability to predict risk for the progression of treated chronic periodontitis. AIMS: to study if the outcomes of supportive periodontal therapy (SPT) based on a multi-factorial periodontal risk assessment are influenced by IL-1 gene polymorphism (IP) status. MATERIAL AND METHODS: Information about the IP and smoking status, clinical periodontal conditions and age related bone level measurements were used to calculate a peridontal risk assessment model (PRA). The surface area of this diagram was calculated for 224 subjects who had participated in an SPT program over four years. Baseline and 4-year follow-up data were studied in relation to the IP status. RESULTS: Positive IP tests were obtained for 80/224 (35.7%) of the subjects. At baseline the mean PRA for the IP positive group was 79.9 units, which at year four had increased to 81.3 units (mean diff: 1.4 units, S.D.+/-16.5, p<0.45, 95% CI: 2.3 to 5.1). At baseline and year four the mean PRA for the IP negative group was 44.2 and 38.6 units, respectively. This difference was statistically significant (mean diff: 5.6, S.D.+/-16.1, p<0.001, 95% CI: 3.0 to 8.3). Independent t-tests confirmed that the IP status was significantly associated with a less favorable change in PRA over the four-year period (PRA difference: 7.04, t=3.01, p<0.003, 95% CI: 2.4 to 11.65). Bleeding on probing, and probing depth values alone did not differ between positive and negative IP status. Regression analysis demonstrated that the best-fit model for change in PRA included bleeding on probing at baseline, IP status, proportional alveolar bone loss in relation to the age, and gender. CONCLUSION: The PRA allowed the assessment of the outcomes of SPT therapy. Subjects with positive IP did not respond to individualized SPT as favorably as did IP negative subjects.

Periodontal conditions and service utilization behaviors in a low income adult population.

PURPOSE: Dental services utilization varies and access to periodontal therapy is not uniform. The objectives were to study an adult population of Medicaid eligible subjects in the Kitsap County, State of Washington, USA: (1) to assess their oral health status, specifically periodontal conditions, and (2) to assess their use of dental services and behavioral beliefs in relation to dental diseases. MATERIALS AND METHODS: 1500 randomly selected eligible households were invited to a cost-free dental examination. The Periodontal Screening and Recording (PSR) index and six bitewing x-ray films were obtained. Subjects responded to a service utilization questionnaire. A telephone interview was performed with 100 randomly selected eligible subjects to assess their behavioral beliefs about dentistry. RESULTS: 132 (8.8%) of the contacted subjects responded while only 4.5% came to the clinical examination. The mean age of the subjects was 35.0 years (S.D. +/- 13.6, range 18 to 78 years) and 73.4% were women. Bleeding on probing was found in 82.8%, and 7.8% of the subjects had teeth with suppurating gingival conditions. Supra, or sub-gingival calculus could be identified in 95.3% of the subjects. Probing depths > 5.5 mm (not accounting for surfaces of third molars) were found in 11.3%, and radiographic evidence of vertical defects > or = 3 mm in 47% of the subjects. Tooth decay in need of urgent dental care was found in 75% of the subjects. Cost (63.2%) and lack of dental insurance (51.3%) were primary factors for not seeking care but 48.7% had no desire to enroll in a "no cost" dental therapy program. Dental fear was an obstacle to care in only 2.6% of the subjects. CONCLUSION: Primary barriers to the utilization of dental services in low income, uninsured populations were: (1) a pre-occupation with other daily issues, financial being the greatest, (2) an attitude of waiting for a problem to occur before seeking dental care, (3) that tooth extraction is the solution or only available treatment option.

Distribution of erm(F) and tet(Q) genes in 4 oral bacterial species and genotypic variation between resistant and susceptible isolates.

BACKGROUND: Bacteroides forsythus, Porphyromonas gingivalis and Prevotella intermedia are Gram-negative anaerobic bacteria that are currently considered potential periopathogens. Prevotella nigrescens has recently been separated from P. intermedia and its rôle in periodontitis is unknown. The erm(F) gene codes for an rRNA methylase, conferring resistance to macrolides, lincosamides and streptogramin B (MLSB), and the tet(Q) gene for a ribosomal protection protein, conferring resistance to tetracycline. The presence of these resistance genes could impair the use of antibiotics for therapy. PURPOSE: The aim of this study was to determine the carriage of erm(F) and tet(Q), and genetic variability of 12 Porphyromonas gingivalis, 10 Prevotella intermedia, 25 Prevotella nigrescens and 17 Bacteroides forsythus isolates from 9 different patient samples. METHODS: We used polymerase chain reaction (PCR) for detecting antibiotic resistance genes, and pulsed-field gel electrophoresis (PFGE) for detecting genetic variability among the isolates. RESULTS: Thirty-one (48%) isolates were resistant to both erythromycin and tetracycline and carried the erm(F) and tet(Q) genes, eight (13%) were tetracycline resistant and carried the tet(Q) gene, 9 (14%) were erythromycin resistant and carried the erm(F) gene, and 12 (19%) isolates did not carry antibiotic resistance genes. PFGE was used to compare isolates from the same patient and isolates from different patient samples digested with XbaI. No association was found between antibiotic resistance gene carriage and PFGE patterns in any species examined. All isolates of the same species from the same patient had highly related or identical PFGE patterns. Isolates of same species from different patients had unique PFGE pattern for each species tested. CONCLUSION: All isolates of the same species from any one patient were genetically related to each other but distinct from isolates from other patients, and 66% of the patients carried antibiotic resistant isolates, which could impair antibiotic therapy.

Serum IgG to heat shock proteins and Porphyromonas gingivalis antigens in diabetic patients with periodontitis.

BACKGROUND: Past studies have reported a correlation between the presence and severity of periodontitis and serum antibody titers to species-specific antigens of Porphyromonas gingivalis or to cross-reactive antigens, such as lipopolysaccharide (LPS) and heat shock proteins (HSP), shared between P. gingivalis and other bacteria. Our recent study of periodontal treatment outcome in insulin-dependent (type 1) diabetes mellitus patients with severe periodontitis (IDDMI/periodontitis) resulted in two key findings: 1. serum glutamic acid decarboxylase autoantibody (GAD65 Ab) levels were significantly associated with periodontal pocket depth change (PDC) and 2. serum IgG titers to P. gingivalis cells were positively associated with GAD65 Ab level in seropositive (GAD65 Ab +) patients. We have therefore hypothesized that profiles of serum autoantibody levels and IgG titers, to P. gingivalis-specific antigens may be useful in assessing risk for refractory periodontitis in such patients. AIM: To determine whether PDC resulting from non-surgical periodontal treatment can be predicted using profiles of baseline IgG titers to P. gingivalis-specific antigens, human HSP, and GAD65. METHODS: PDC was assessed two months after non-surgical periodontal treatment of 7 GAD65 Ab + and 11 GAD65 AbIDDM/periodontitis patients. Pretreatment titers to GAD65, recombinant human heat shock proteins (HSP90, HSP70, and HSP60), and various P. gingivalis antigens were measured using radioligand precipitation or enzyme-linked immunosorbent (ELISA) assays and compared to the same measurements for 154 recent-onset IDDM patients and 46 non-diabetic controls. RESULTS: Median titers (ELISA units) to HSP90 and HSP70 were significantly higher than non-diabetic controls for GAD65 Ab + (p degrees = 0.002) and GAD65 Ab- (p = 0.034) IDDM/periodontitis patients, respectively. Multivariate regression analysis indicated significant partial correlation of PDC with log-transformed titers to HSP90 (r = - 0.62, p = 0.008), HSP70 (r = + 0.62, p = 0.009), GAD65 (r = - 0.60, p = 0.01) and P. gingivalis LPS (r = - 0.5 1, p = 0.04). Furthermore, hierarchical clustering of baseline profiles of log-transformed HSP90, HSP70, and GAD65 Ab titers sorted patients into two distinct clusters with significantly different median PDC (1.45 min, n = 10 vs. 0.65 min, n = 8; p = 0.016, Mann-Whitney). CONCLUSION: Pretreatment profiles of serum antibody titers to HSP90, HSP70, GAD65, and P. gingivalis LPS may be useful for predicting which patients with IDDM/periodontitis will have a poor response to non-surgical periodontal therapy.

Presence and antibiotic resistance of Porphyromonas gingivalis, Prevotella intermedia, and Prevotella nigrescens in children.

BACKGROUND/AIMS: Only limited information exists about the prevalence in children of pathogens associated with periodontitis. The aim of the present study was to determine by culture whether 8-11-year-old children carry Porphyromonas gingivalis, Prevotella intermedia, and/or P. nigrescens in samples from the gingiva and/or the buccal mucosa taken before, and after caries treatment and oral hygiene instruction. A second aim was to assess the proportion of subjects who had gram-negative anaerobes carrying the tet(Q) and erm(F) genes, suggesting antibiotic resistance to tetracycline or erythromycin. METHOD: A total of 150 children provided gingival and buccal swab bacterial samples that were cultured for P. gingivalis, P. intermedia, and P. nigrescens. The species was verified using DNA-DNA hybridization with species-specific probes made from the variable region of the 16S rRNA sequences. Antibiotic-resistant genes, tet(Q) and erm(F), were identified using specific DNA-DNA hybridization with specific DNA probes. RESULTS: A total of 116 isolates of black-pigmented bacteria were cultured from 47 (31%) of 150 children. Five isolates were identified as P. gingivalis, 29 as P. intermedia, 33 as P. nigrescens, and 49 as other species. In general, the bacteria were not culturable at more than one time period. We found that 55% of these 47 children harbored black pigmented bacteria that carried either one or both of the two antibiotic-resistant genes studied (tet(Q), and erm(F)). CONCLUSION: The present study demonstrated that children not exposed to regular dental treatment carry bacteria outside the gingival sulcus that have been associated with periodontitis, and that standard treatment procedures may not clear the presence of the putative pathogens. In addition, antibiotic-resistant genes are common in identifiable gram-negative anaerobes, including putative pathogens.

Response to direct and indirect recruitment for a randomised dental clinical trial in a multicultural population of elders.

OBJECTIVES: Recruitment for randomised clinical trials and community-based studies has received little attention in the dental literature. The goal of this study was to report on our experiences with direct and indirect recruitment methods for a trial to prevent tooth loss in elders. METHODS: A direct approach, consisting of an introductory lecture with the help of a local contact person in each of the nine community centres, resulted in 208 recruits mostly from minority non-English speaking communities (52%), whereas the other 192 recruits who responded to newspaper announcements (48%) were, in large part, from the English-speaking community. RESULTS: The response suggests that a more direct and culturally specific approach is more productive when recruiting elders from ethnic minority groups, whereas elders from the dominant culture can be recruited indirectly and for about half the financial cost through newspaper announcements. CONCLUSION: We conclude, therefore, that both direct and indirect methods are needed to recruit a multiethnic sample of subjects for a trial.

Predictors of oral health quality of life in older adults.

There is limited information regarding oral health status and other predictors of oral health-related quality of life. An association between oral health status and perceived oral health-related quality of life (OHQOL) might help clinicians motivate patients to prevent oral diseases and improve the outcome of some dental public health programs. This study evaluated the relationship between older persons' OHQOL and their functional dentition, caries, periodontal status, chronic diseases, and some demographic characteristics. A group of 733 low-income elders (mean age 72.7 [SD = 4.71, 55.6% women, 55.1% members of ethnic minority groups in the U.S. and Canada) enrolled in the TEETH clinical trial were interviewed and examined as part of their fifth annual visit for the trial. OHQOL was measured by the Geriatric Oral Health Assessment Index (GOHAI); oral health and occlusal status by clinical exams and the Eichner Index; and demographics via interviews. Elders who completed the four-year assessment had an average of 21.5 teeth (SD = 6.9), with 8.5 occluding pairs (SD = 4.6), and 32% with occlusal contacts in all four occluding zones. Stepwise multiple regressions were conducted to predict total GOHAI and its subscores (Physical, Social, and Worry). Functional dentition was a less significant predictor than ethnicity and being foreign-born. These variables, together with gender, years since immigrating, number of carious roots, and periodontal status, could predict 32% of the variance in total GOHAI, 24% in Physical, 27% in Social, and 21% in the Worry subscales. These findings suggest that functional dentition and caries influence older adults' OHQOL, but that ethnicity and immigrant status play a larger role.

Ethnicity and oral health in community-dwelling older adults.

Epidemiological studies consistently have found differences in oral health status between white and non-white elders. This has been attributed primarily to lack of access to dental care, especially preventive services. The study reported here examined psychosocial factors in an attempt to explain these differences.
