Psychometric properties of the General Oral Health Assessment Index (GOHAI) and dental status of an elderly Mexican population.

OBJECTIVES: To evaluate the psychometric properties of the Geriatric/General Oral Health Assessment Index, Spanish version (GOHAI-Sp) and their relationship with the dentition status of an elderly Mexican population as a discriminatory validation. METHODS: A cross-sectional study was conducted among persons over 60 years of age. A Spanish version the GOHAI-Sp validated in Spain in institutionalized geriatric patients was used. Clinical evaluation was done in order to determine experience with coronal and root caries. RESULTS: Measurement of internal consistency of the GOHAI gave a Cronbach alpha coefficient of 0.77 for the 12 items. In factorial analysis, one factor alone was capable of explaining 30.6 percent of the total variance. The factor that was most apparent in the factorial analysis of the GOHAI had coefficients > 0.30 for the 12 items. The Kaiser-Meyer-Olkin measure of simple adequacy was 0.81 and the Bartlett's sphericity test was 1,748.55 with 66 degrees of freedom (P < 0.001). There was a statistically significant difference in the GOHAI scores between the responses to self-perception of oral and general health (P < 0.001). Also, there was a statistically significant low correlation coefficient between the missing and filled components of the DMFT index and the number of healthy and functional teeth (P < 0.05). CONCLUSIONS: The GOHAI has acceptable psychometric properties, discriminates between self-perception of oral health and self-perception of general health, and correlates with past caries experience measured by the DMFT index.

[Hospital discharges for oral cancer in the Mexican Institute of Social Security, 1991-2000]. / Egresos hospitalarios por cáncer bucal en el IMSS (1991-2000).

A descriptive study based on the secondary analysis of the Unique System of Information database, Subsystem 13 of Hospital discharges to oral cancer of the Mexican Institute of Social Security (IMSS) during the decade from 1991 to 2000, it was considered all the registrations for oral cancer according to the International Classification of Diseases ICD-9. During that time, 8,800 hospital discharges were registered for oral cancer, out of which 64.6% (n = 5682) were men. The men: women ratio showed 1.8 men per admitted woman for oral cancer. The mortality gross rate for oral cancer was of 50.4 for each 100,000 hospital discharges with a significantly descendent trend. Hospital discharges rate by age group was specifically concentrated in population to 35 years-old or more, registering themselves the greater rates as of the 55 years-old. The hospital average stay was of 5.1 days. According to the topography of the oral cavity, we found that the tongue (25.1%), principal salivary glands (24.0%) and tonsil-oropharynx (14.2%) were the main places where this pathology presented. During the above decade, the oral cancer hospital discharges registered in the IMSS didn't show an increasing pattern.

Oral health service utilization by elderly beneficiaries of the Mexican Institute of Social Security in México city.

BACKGROUND: The aging population poses a challenge to Mexican health services. The aim of this study is to describe recent oral health services utilization and its association with socio-demographic characteristics and co-morbidity in Mexican Social Security beneficiaries 60 years and older. METHODS: A sample of 700 individuals aged 60+ years was randomly chosen from the databases of the Mexican Institute of Social Security (IMSS). These participants resided in the southwest of Mexico City and made up the final sample of a cohort study for identifying risk factors for root caries in elderly patients. Sociodemographic variables, presence of cognitive decline, depression, morbidity, medication consumption, and utilization of as well as reasons for seeking oral health services within the past 12 months were collected through a questionnaire. Clinical oral assessments were carried out to determine coronal and root caries experience. RESULTS: The sample consisted of 698 individuals aged 71.6 years on average, of whom 68.3% were women. 374 participants (53.6%) had made use of oral health services within the past 12 months. 81% of those who used oral health services sought private medical care, 12.8% sought social security services, and 6.2% public health services. 99.7% had experienced coronal caries and 44.0% root caries. Female sex (OR = 2.0), 6 years' schooling or less (OR = 1.4), and caries experience in more than 22 teeth (OR = 0.6) are factors associated with the utilization of these services. CONCLUSION: About half the elderly beneficiaries of social security have made use of oral health services within the past 12 months, and many of them have to use private services. Being a woman, having little schooling, and low caries experience are factors associated with the use of these services.

Oral health status in older adults with social security in Mexico City: Latent class analysis.

OBJECTIVE: To explore the oral health status through a latent class analysis in elderly social security beneficiaries from Southwest Mexico City. MATERIAL AND METHODS: Cross-sectional study of beneficiaries of the State Employee Social Security and Social Services Institute (ISSSTE, in Spanish) and the Mexican Institute of Social Security (IMSS, in Spanish) aged 60 years or older. Oral health conditions such as edentulism, coronal and root caries (DMFT and DFT ≥ 75 percentile), clinical attachment loss (≥ 4 mm), and healthy teeth (≤ 25 percentile) were determined. A latent class analysis (LCA) was performed to classify the oral health status of dentate patients. RESULTS: In total, 336 patients were included (47.9% from the ISSSTE and 52.1% from the IMSS), with an average age of 74.4 (SD = 7.1) years. The 75th percentile of the DMFT = 23 and of the DFT = 2. Of the patients, 77.9% had periodontal disease. The 25th percentile of healthy teeth = 4. A three class model is adequate, with a high classification quality (Entropy = 0.915). The patients were classified as "Edentulous" (15.2%), "Class 1 = Unfavorable" (13.7%), "Class 2 = Somewhat favorable" (10.4%), and "Class 3 = Favorable" (60.7%). Using "Class 3 = Favorable" as a reference, there was an association (OR = 3.4; 95% CI = 1.8-6.4) between being edentulous and being 75 years of age and over, compared with the 60- to 74-year age group. CONCLUSION: The oral health in elderly social security beneficiaries is not optimal. The probability of becoming edentulous increases with age. A three-class model appropriately classifies the oral health dimensions in the elderly population. Key words:Elderly, Latent class analysis (LCA), oral health, social security, Mexico.

A prediction model for root caries in an elderly population.

OBJECTIVES: To identify factors associated with root caries development in a 12- month period, in an elderly Mexican population, so as to develop a prediction model for the occurrence of root caries. METHODS: A case-cohort study was carried out with 698 randomly selected beneficiaries of the Mexican Institute of Social Security (IMSS), residing in the southeast of Mexico City. Initially, base line (t0) data regarding sociodemographic variables, general health, general and oral healthy habits, salivary conditions, cariogenic microorganisms and oral health clinical indicators were collected. Twelve months from the date of the first clinical evaluation (t1), a new examination was carried out to determine the root caries increment. Variables that showed a significant association (P ≤ 0.05) with the root caries increment were included in the prediction model. RESULTS: Six hundred and ninety-eight elderly subjects were included in the cohort (t0), with 76.1% (n = 531) of the elderly patients followed up at 12 months (t1). Incidence of root caries was 21.7% (n = 115), a mean root caries increase of 0.4 (1.0) surfaces. The variables, DLBA limitations (Yes), smoking (Yes), mouthwash (No), Mutans streptococci (≥105 CFU/ml), healthy root surfaces (≥6) and Root Caries Index (≥8%), showed a statistically significant association (P < 0.05). This model showed a correct classification in 80.0% (n = 425) and an area under the Receiver Operating Characteristic curve of 0.75. CONCLUSIONS: This is a good prediction model for the 12 months root caries increment in this population of elderly Mexicans.

Métodos: Muestra representativa de adultos mayores derechohabientes del Instituto Mexicano del Seguro Social del suroeste de la Ciudad de México. Se realizaron entrevistas domiciliarias para conocer las características de la muestra y aplicación de los instrumentos Geriatric/General Oral Health Assessment Index y Oral Impacts on Daily Performances. Evaluación clínica para determinar la experiencia de caries coronal y caries radicular. Resultados: Un total de 531 sujetos de 60 años y más participaron, 68.4% mujeres. La media (desviación estándar) de edad fue de 71.4 (7.0) años. El Geriatric/General Oral Health Assessment Index presentó una media de 46.8 (6.2), y 4.1 (12.4) para el Oral Impacts on Daily Performances. La escolaridad mayor de seis años, no presentar limitaciones, con deterioro cognitivo y sin depresión, presentaron una media mayor del puntaje del Geriatric/General Oral Health Assessment Index en comparación con los que no presentaban (p < 0.05). La escolaridad mayor de seis años, con una actividad laboral remunerada y sin depresión, presentaron una media menor del puntaje del Oral Impacts on Daily Performances en comparación a los que no presentaban (p < 0.05). Existe una correlación entre el Geriatric/General Oral Health Assessment Index y componentes obturados, dientes funcionales (p < 0.05). Los componentes perdidos, obturados e índice caries coronal, así como coronas sanas y dientes funcionales presentaron una correlación con el Oral Impacts on Daily Performances (p < 0.05). Conclusión: El Geriatric/General Oral Health Assessment Index tuvo mayor discriminación en las características de la población y el Oral Impacts on Daily Performances presentó mayor correlación con el estado de la dentición.

Objective: To determine the behavior of the Geriatric/General Oral Health Assessment Index as well as the Oral Impacts on Daily Performances as effective measures in oral-dental health related to quality of life in senior citizens in a given population. Methods: A representative sample of senior citizens entitled to medical services at the Instituto Mexicano del Seguro Social (Mexican Institute of Social Security) located in the southwest region of Mexico City. Home interviews were conducted in order to ascertain the sample's characteristics as well as the application of the Geriatric/General Oral Health Assessment Index and Oral Impacts on Daily Performances instruments. Clinical evaluation in order to determine experience of crown caries (CPO-D) and root caries CO-R). Results: A total of 531 subjects aged 60 years and over participated in the study, of which 68.4% were female. Age average (AA) was 71.4 years (7.0). Geriatric/General Oral Health Assessment Index exhibited a mean of 46.8 (6.2) and Oral Impacts on Daily Performances showed 4.1 (12.4). Subjects included in the sample had attended school for over 6 years, did not present limitations of cognitive deterioration, and were depression-free, exhibited a higher mean in Oral Impacts on Daily Performances score than those which did not present those characteristics (p < 0.05). Six or more years of schooling with paid work and depression-free subjects presented lesser Oral Impacts on Daily Performances scores when compared to those who did not. (p < 0.05) A correlation was found between the Geriatric/General Oral Health Assessment Index and filled components, functional teeth (p > 0.05). Filled and lost components and CPO-D index as well as healthy crowns and functional teeth exhibited a correlation with Oral Impacts on Daily Performances (p < 0.05). Conclusion: Geriatric/General Oral Health Assessment Index exhibited higher discrimination in the population's characteristics whereas Oral Impacts on Daily Performances showed higher correlation with the state of the dentition.

A simplified caries risk test in stimulated saliva from elderly patients.

OBJECTIVES: To evaluate and compare lactobacilli species (LB) and mutans streptococci (MS) caries risk identification by means of a Caries Risk Test Bacteria (CRT Bacteria test), with a conventional laboratory test (CLT), as well as their correlation with the dental caries experience [(decayed-missing-filled teeth (DMFT index)] in subjects 60 years of age and older. DESIGN: Cross-sectional study. SETTING: Epidemiologic and Health Service Research Unit, Aging Area. XXI Century National Medical Center; Mexican Institute of Social Security (IMSS). SUBJECTS: A total of 696 elderly subjects residing in southwestern Mexico City. METHODS: The DMFT index was determined in 696 subjects and saliva collected by stimulation. This was processed with a CRT Bacteria test and a CLT (the gold standard) test. Subjects with high [> or =10(5) colony forming units (CFU)/ml] and low caries risk (<10(5) CFU/ml) were assessed. RESULTS: The CRT Bacteria test sensitivity (Sen) and specificity (Spe) were 0.97 and 0.86 for LB, respectively, with positive and negative predictor values of 0.92 and 0.95 respectively. For MS, Sen and Spe was 0.92 and 0.90, and 0.96 and 0.81 respectively. The receiver operating characteristic area under the curve (ROC area) in LB and MS was 0.94 and 0.89, respectively; thus, a correlation existed between the caries experience and the LB and MS caries risk, similar to that present with the CLT test. CONCLUSION: The CRT Bacteria test shows similar results to those of the CLT test in subjects 60 years of age and over.

[State of dentition and its impact on the capacity of elders to perform daily activities]. / Estado de la dentición y sus efectos en la capacidad de los ancianos para desempeñar sus actividades habituales.

OBJECTIVE: The aim of this study was to evaluate the effect of dental state on the capacity of elderly individuals to carry out their daily activities during the previous six months. MATERIAL AND METHODS: A transversal study was conducted in the Mexican Institute of Social Security (IMSS) with insured elderly persons residing in southwestern Mexico City. Home interviews were conducted to gather sociodemographic data, data on the use of oral health services, problems in carrying out daily activities, and their relationship with the state of dentition over the past six months, utilizing the Oral Impacts on Daily Performance (OIDP) index. Later, three oral health professionals trained in determining the state of dentition according to World Health Organization (WHO) criteria performed a clinical examination on each elderly subject. RESULTS: A total of 540 elderly individuals were studied. The prevalence of elderly persons with problems in carrying out their daily activities was 21.5%. The main problems in daily activities were eating (14.4%), speaking (8.7%), not becoming irritated (5.4%), brushing their teeth(5%), and inability to enjoy contact with people (4.4%). There is a positive OIDP correlation between number of teeth lost and the decayed, missing, filled teeth(DMFT) index (p<0.05) and a negative correlation with the number of functional and filled teeth. CONCLUSIONS: The state of dentition in the elderly has repercussions on the capacity to carry out daily activities, with quality of life most seriously affected with regard to eating and enjoying food, as well as with respect to correct pronunciation.
