RESUMO
OBJECTIVE: To assess the experience, prevalence, need for treatment and economic impact of caries among students 6-12 years old in four cities in Mexico. BASIC RESEARCH DESIGN: Cross-sectional clinical study. SETTING: Elementary public schools. PARTICIPANTS: 500 schoolchildren aged 6 to 12 years. METHOD: Oral clinical examinations using WHO criteria for caries in the primary (dmft) and permanent (DMFT) dentitions. MAIN OUTCOME MEASURES: Indicators of caries in the primary and permanent dentitions: experience, prevalence, severity and the Significant Caries Index. In addition, we calculated the treatment needs, dental care rate and cost of care. RESULTS: dmft in the primary dentition was 2.59±2.83, and DMFT was 0.82±1.44 in the permanent dentition. Caries prevalence reached 67.7% in the primary and 34.1% in permanent dentition. The treatment needs index was 85.9% and 91.3% in the primary and permanent dentitions, respectively; the dental care index was 13.9% and 8.5%, respectively. The cost of care for caries in the primary dentition was estimated at $22.087 millions of international dollars (PPP US$) when amalgam was the restorative material used, and PPP US$19.107 millions for glass ionomer. For the permanent dentition, the cost was PPP US$7.431 millions when amalgam was used and PPP US$7.985 millions when resin/composite was used as restorative material. CONCLUSIONS: The prevalence and experience of caries in the primary dentition were 50% greater than those of other studies carried out in Mexico. In the permanent dentition they were less. There is considerable need for the treatment of caries and minimal experience with restorative care. The cost of care for caries may be assumed to be high for a health system such as Mexico's.

OBJECTIVE: To examine the influence of collectivist orientation (often called familismo when applied to the Latino sub-group in the United States) in oral health discussion networks. BASIC RESEARCH DESIGN: Through respondent-driven sampling and face-to-face interviews, we identified respondents' (egos) personal social network members (alters). Egos stated whom they talked with about oral health, and how often they discussed dental problems in the preceding 12 months. PARTICIPANTS: An urban community of adult Mexican-American immigrants in the Midwest United States. We interviewed 332 egos (90% born in Mexico); egos named an average of 3.9 alters in their networks, 1,299 in total. METHOD: We applied egocentric network methods to examine the ego, alter, and network variables that characterize health discussion networks. RESULTS: Kin were most often leveraged when dental problems arose; egos relied on individuals whom they perceive to have better knowledge about dental matters. However, reliance on knowledgeable alters decreased among egos with greater behavioral acculturation. CONCLUSIONS: This paper developed a network-based conceptualization of familismo. We describe the structure of oral health networks, including kin, fictive kin, peers, and health professionals, and examine how networks and acculturation help shape oral health among these Mexican-Americans.

OBJECTIVE: To identify barriers and beliefs influencing oral health and dental care-seeking among Mexican-Americans. RESEARCH DESIGN: Interviews and Likert-scale survey questions were utilized to explore urgent and preventive dental care-seeking, oral hygiene habits and lifestyle practices. Thirty-three interviews were conducted with 16 adults (ages 33-52), and 17 adolescents (ages 14-19). RESULTS: Teens identified the same main barriers to accessing dental care as adults: high cost, financial limitations and lack of insurance. Most Mexican-Americans agreed with the belief that everyone will need urgent dental treatment and the majority believed that going to a dentist in private practice instead of the Emergency Room was important. Although adults recognized the importance of preventive dental care, half reported being unlikely to seek such care while half of teens reported that they were likely to do so. Adults reported relying equally on themselves and on peers to make dental care decisions, while teens mostly depended on others to make decisions about urgent and preventive care. Virtually all respondents believed regular brushing to be important and many flossing too. A major barrier to flossing was being unsure of the proper technique. Another barrier to better oral health was not having seen messages encouraging changes in lifestyle. CONCLUSIONS: This study found that Mexican-American teens and adults may experience oral health similarly. Teens do not have more positive oral health beliefs and encounter mostly the same barriers to care as adults.

OBJECTIVE: To compare a limited array of chewing-stimulated saliva features (salivary flow, pH and buffer capacity) in a sample of elderly Mexicans with clinical, sociodemographic and socio-economic variables. SUBJECTS AND METHODS: A cross-sectional study was carried out in 139 adults, 60 years old and older, from two retirement homes and a senior day care centre in the city of Pachuca, Mexico. Sociodemographic, socio-economic and behavioural variables were collected through a questionnaire. A trained and standardized examiner obtained the oral clinical variables. Chewing-stimulated saliva (paraffin method) was collected and the salivary flow rate, pH and buffer capacity were measured. The analysis was performed using non-parametric tests in Stata 9.0. RESULTS: Mean age was 79.1 ± 9.8 years. Most of the subjects included were women (69.1%). Mean chewing-stimulated salivary flow was 0.75 ± 0.80 mL/minute, and the pH and buffer capacity were 7.88 ± 0.83 and 4.20 ± 1.24, respectively. Mean chewing-stimulated salivary flow varied (p < 0.05) across type of retirement home, tooth brushing frequency, number of missing teeth and use of dental prostheses. pH varied across the type of retirement home (p < 0.05) and marginally by age (p = 0.087); buffer capacity (p < 0.05) varied across type of retirement home, tobacco consumption and the number of missing teeth. CONCLUSIONS: These exploratory data add to the body of knowledge with regard to chewing-stimulated salivary features (salivary flow rate, pH and buffer capacity) and outline the variability of those features across selected sociodemographic, socio-economic and behavioural variables in a group of Mexican elders.
RESUMO
PURPOSE: The aim of this study was to determine the reasons for which erupted third molars (3M) are extracted in a sample of Mexican patients. SUBJECTS AND METHODS: A retrospective cross-sectional study was performed on a sample of 83 patients attending exodontia (minor oral surgery) clinics of a public university in Mexico (Autonomous University of Hidalgo State). The outcome variable was the reason for extractions using Kay and Blinkhorn's classification. The independent variables were age, gender, arch and tooth number according to the World Health Organization (WHO). For statistical analysis, we used the Chi-squared test in Stata 9.0. RESULTS: Eighty-three patients underwent 150 3M extractions. Mean age was 38.67 ± 13.96 years, and 71.1% were female. The four reasons for 3M extraction were prosthetic (44.0%), followed by orthodontic (24.7%), dental caries (20.0%) and periodontal disease (11.3%). Differences were observed in the reasons for 3M extractions across age groups (p < 0.05). No significant differences existed between men and women (p > 0.05), or the WHO tooth number (p > 0.05). CONCLUSION: Women and patients 18 to 34 years of age had erupted 3M extracted more frequently, primarily for prosthetic reasons. The age profile indicated a trend in demand for services that differ from those of overall tooth extractions, but not for the trend across gender.
RESUMO
OBJECTIVE: To determine the Treatment Needs Index (TNI) for dental caries, the restorative Care Index (CI), and to introduce a Tooth Extractions Index (TEI) to estimate past and current treatment needs among Mexican adolescents. SUBJECTS AND METHODS: A descriptive cross-sectional study was carried out on 1538 adolescents aged 12 and 15 years in the state of Hidalgo, Mexico, to collect decayed, missing, filled teeth (DMFT) data to describe TNI, CI and TEI indices. RESULTS: Higher TNI was identified in younger male teenagers who had always lived in the same community, without dental visits in the last year, and who had poorer socio-economic markers. Higher CI was found in older, female subjects who had moved in their lifetimes to a new community in the area, with dental visits in the last year and who had better socio-economic markers. Higher TEI was found in older, female teenagers who had moved in their lifetimes to a new community in the area, without dental visits in the last year, and who had worse socio-economic markers. CONCLUSIONS: We observed high rates of treatment needs for dental caries and little experience of restorative treatment. While dental extractions due to advanced caries should ideally be zero, relatively few adolescents had this treatment experience. Despite the fact that the overall background of these adolescents is rather homogeneous, it was still possible to find that treatment needs' indices (past and present needs) appeared to be modified by sociodemographic and socio-economic variables.

OBJECTIVE: To determine the prevalence of daily tooth brushing and evaluate some variables associated. SUBJECTS AND METHODS: A cross-sectional study was carried out in 320 schoolchildren six to nine years old in Campeche, Mexico. Information on sociodemographic and socio-economic variables, oral hygiene practices and attitudes were collected through a questionnaire. The frequency of tooth brushing was categorized as "0" = fewer than seven times/week, "1" = at least once a day. In the analysis, nonparametric tests were used. RESULTS: Mean age was 6.99 +/- 1.00 years, 52.5% were boys. The prevalence of daily tooth brushing was 81.6%. In bivariate analysis, the prevalence of tooth brushing was higher (p < 0.05) among the children of mothers with higher schooling (9.80 years vs 8.47 years, p < 0.05), and in younger children (84.6% in 6-7-year olds vs 71.2% in 8-9-year olds, p < 0.05). A slight, non-significant association (p < 0.10) was noted between the current frequency of tooth brushing and an earlier age when the child first started brushing with toothpaste. There were no statistically significant differences (p > 0.05) in the frequency of tooth brushing by gender or by the mother's attitude toward the oral health of her child. CONCLUSIONS: The prevalence of daily tooth brushing was high compared to other studies. Mother's maximum level of schooling (as an indicator of socio-economic position) was associated with higher frequency of tooth brushing. Maternal characteristics are associated with the oral health behaviour of their children.

OBJECTIVES: Current UK and US economic conditions have re-focussed attention on the need to deliver dental care with limited finance and resources. This raises hard questions determining which services will be offered and what they should achieve to satisfy public demands and needs. We consider impending dental health reforms in the US and UK within the context of contemporary experiences to identify issues and delivery goals for the two nations. BACKGROUND: The paper provides a brief history and background of the development of social dental care models in the UK and US, highlighting some differences in state-funded delivery of dental care. SHIFTING DEMAND: From the 1950s, demand for dental treatment has increased and acquired a more complex composition growing from predominantly surgical and restorative treatment to encompass preventive care and cosmetic services. PRIORITISING CARE ACCORDING TO NEED: Despite improvements in general health and technology, inequalities in access and utilisation of dental care are still experienced, primarily by groups with low socio-economic status. DELIVERY: BALANCING RESOURCES, DEMAND AND NEED: In developing and delivering reform agendas, much can be learned from previous policy interventions. Pressures of cost, coverage, and capacity, besides demand versus need must be carefully considered and balanced to deliver quality service and value for users and taxpayers. CONCLUSIONS: Ethical and moral consideration should be given to making services needs-driven to address high treatment requirements rather than the high care demands of the worried well. This challenge brings the additional political pressure of convincing many of the voters (and subsequent complainers) that their demands may be less important than the needs of others.

AIM: To determine whether maternal characteristics and treatment needs are associated with dental health services utilization (DHSU) in school children. MATERIALS AND METHODS: A cross-sectional study in 1373 school children aged 6- 12 years in elementary schools in Campeche, Mexico collected family and sociodemographic characteristics; an oral examination was conducted. The dependent variable was DHSU in the year preceding the study. RESULTS: DHSU prevalence was 65.5%. The variables associated (p<0.05) with DHSU in the final multivariate model were age (OR=1.27), maternal schooling (OR=1.07), mother's attitude toward oral health (OR=1.39), frequency of tooth brushing (OR=1.83), enamel defects (OR=1.55), and unmet oral health needs (moderate: OR=1.42 and high: OR=2.30). CONCLUSION: Specific sociodemographic and maternal variables were associated with DHSU. Strategies are needed to increase appropriate and timely use of services to improve health status.

AIM: To determine if the presence of developmental enamel defects (DED) in the primary dentition is a risk indicator for the presence of DED in the permanent dentition in children with mixed dentition, as well as others factors. MATERIALS AND METHODS: A cross-sectional study was undertaken in 1296 school children ages six to 72 years. The DED [FDI; 1982] in both dentitions were identified by means of an oral exam scoring enamel opacities [classified as demarcated or diffused], and enamel hypoplasia. Sociodemographic and socioeconomic variables were collected through a questionnaire. Socioeconomic status (SES) was determined based on the occupation and maximum level of education of parents. Statistical analysis included logistic regression. RESULTS: Mean age of participants was 8.40 +/- 1.68; 51.6% were boys. DED prevalence was 7.5% in the permanent dentition and 10.0% in the primary dentition. The logistic regression model, adjusting for sociodemographic and socioeconomic variables, showed that for each primary tooth with DED, the odds of observing DED in the permanent dentition increased 7.38 times [95% CI = 1.17-1.64; p < 0.001]. CONCLUSION: An association between DED presence in both permanent and primary dentitions was observed. Further studies are necessary to fully characterise such relationship.

Systemic antibiotics have been recommended for the treatment of destructive periodontal disease. Our goal was to relate antibiotic use for medical or dental reasons to subsequent tooth loss in a cohort of 12,631 persons with destructive periodontal disease. After adjustment for age, smoking, and other confounders, the dispensing of antibiotics for 1-13 days, 14-20 days, or 21 or more days was not associated with reduced tooth loss [Adjusted rate ratio (RR) = 1.0; 95% Confidence Interval (CI) = 0.8-1.1; RR = 1.2; 95% CI = 0.9-1.4, and RR =1.2, 95% CI =1.0-1.3, respectively]. Numerous subgroup analyses were consistent with these overall null findings, with two exceptions: Longer courses of tetracyclines were associated with reduced tooth loss among persons receiving periodontal care, and penicillin was associated with reduced tooth loss among persons with more severe disease. Long-term, larger randomized trials are needed to provide evidence that antibiotics reduce tooth loss when used in the management of destructive periodontal disease.

BACKGROUND: Professional truck drivers are at high risk of chronic diseases. Further examination of tobacco use and its impact on oral health is warranted - both in terms of the direct association between tobacco use and poor oral health, and in terms of tobacco use being an indicator of poor health behaviors. OBJECTIVE: To estimate the possible association between smoking and dental caries experience in a population with high tobacco use. METHODS: Drivers' licenses are periodically re-issued by the Mexican government and as part of the licensing process a physical exam takes place. We administered a free, standardized questionnaire together with an oral examination (WHO criteria) included in the physical exam, targeting a random sample of applicants in Mexico City. RESULTS: A total of 824 dentate males (mean age 35.5 +/- 10 years) took part in the study, of whom 49.2% were current smokers and 23.2% were former smokers. Caries experience was mean DMFT 8.95 (+/- 6.05). Only 18.0% of participants had 'excellent' or 'good' oral hygiene. The prevalence of 'large' cavities increased as the number of cigarettes/day increased from 14.6% (1-3 cigarettes/day) to 33.3% (> or =10 cigarettes/day). Using multiple linear regressions, we found that older age, poorer oral hygiene, higher education, and greater tobacco exposure were significantly associated with higher caries experience (DMFT). An interaction was observed with oral hygiene and tobacco: drivers that smoked and had 'poor' oral hygiene showed the highest number of large cavities and missing teeth. Health promotion interventions are needed in this at-risk population group.

UNLABELLED: Latin American dental schools are at diverse stages in the continuum of implementation of infection control (IC) programmes that comply with evidence-based recommendations. Poor IC training may result in low compliance and negative attitudes against patients infected with blood borne pathogens (BBP). OBJECTIVE: To evaluate students' knowledge on IC and attitudes toward occupational BBP risks, in six dental schools in Latin America. METHODS: This survey was administered to convenience samples of dental students at one school in Costa Rica; four schools in Mexico, and one in Venezuela. The questionnaire included Likert-type scale evaluations of agreement with statements. Study variables included knowledge about and confidence in recommended IC procedures, degree of concern about HIV and HBV transmission in dental settings, and attitudes toward patients infected with BBP. Possible associations between variables were analysed using Pearson's Chi square and Kruskal Wallis tests. RESULTS: Substantial numbers of students had incomplete knowledge and often lacked confidence on IC and procedures; believed that HIV and HBV could be transmitted during clinical procedures; felt worried about occupational exposure to BBP, and held prejudices towards HIV and HBV infected individuals. CONCLUSIONS: Educational efforts are needed to enhance IC teaching and compliance. Diverse educational resources and international networks for research collaboration are available from organisations specialised in IC, hopefully paving the way to harmonising regional standards.

To determine the prevalence of edentulism in adults aged 18 years and older in Mexico and to describe its distribution in 20 of the 32 States in Mexico, highlighting the experience in the WHO age groups. A secondary analysis of the National Performance Evaluation Survey 2002-2003 (representative at the state level and part of the Word Health Survey) was undertaken. The sample design was probabilistic, stratified and through conglomerates. Data on dental conditions were available only for 20 of the 32 states of Mexico, leading to a total of 24 159 households (N = 54 638 654). The percentage of edentulism was determined as the proportion of subjects that self-reported complete loss of teeth. Data were analyzed using the SVY module for complex surveys in STATA 8.2. The mean age was 41.3 +/- 17.0 years (range 18-99). An estimated 6.3% (N = 3 437 816) of the population > or =18 years was edentulous. Lowest prevalences were observed in the states of Tlaxcala, Puebla and the Estado de Mexico with 3.4%, 3.8% and 4.5%, respectively. Highest prevalences were observed in San Luis Potosí, Colima, and Michoacán with 10.3%, 10.2% and 10.1%, respectively. Following the WHO age groups, the prevalence ranged from 2.4% in the 35-44 group through 25.5% in the 65-74 group. No obvious association between socio-economic and socio-demographic indicators at the state level and prevalence of edentulism was found. The prevalence of complete tooth loss observed in the present study varied greatly across states, although no straightforward association was found with socio-economic and socio-demographic indicators at the state level. This study could serve as a baseline to enable future evaluations of the oral status of Mexican adults and elders, following WHO age groups.

OBJECTIVE: Determine the association between key dental outcomes and added sugar intake using a survey instrument to assess added sugars, which was specifically tailored to immigrant and US-born adults of Mexican origin. METHODS: Hispanic adults of Mexican origin (n = 326; 36.2 ± 12.1 years) completed a self-administered survey to gather acculturation, self-reported dental experiences and self-care practices (eg brushing, flossing, pain, bleeding gums), and socio-demographic information. The survey included a culturally tailored 22-item Added Sugar Intake Estimate (ASIE) that assessed added sugar intake from processed foods and sugar-sweetened beverages in a semiquantitative food frequency questionnaire format. Linear regression, 2-sample t test, and ANOVA were used to evaluate associations of demographic and dental outcomes with daily added sugar intake. RESULTS: Of the mean total daily added sugar intake (99.6 ± 94.6 g), 36.5 ± 44.4 g was derived from sugar-containing foods and snacks, and 63.1 ± 68.2 g from beverages. Participants who reported greater added sugar intake were more likely to have reported the presence of a toothache in the preceding 12 months, having been prescribed antibiotics for dental reasons, being less likely to floss daily, have reported eating or drinking within 1 hour before bed and have lower psychological acculturation (P < .05 for all). Results were comparable when assessing intake from sugar-containing foods/snacks and sugar-sweetened beverages. CONCLUSIONS: This study confirmed the association between added sugar intake and self-reported dental outcomes among adults of Mexican origin and points to an urgent need to improve dietary behaviours in this population.

The Trial to Enhance Elderly Teeth Health (TEETH) was designed to test the impact of regular rinsing with a 0.12% chlorhexidine (CHX) solution on tooth loss, and the causes of tooth loss (caries, periodontal disease and trauma) were also investigated. This paper reports on the effectiveness of a 0.12% CHX solution for controlling caries using a tooth surface (coronal and root) survival analysis. A total of 1,101 low income elders in Seattle (United States) and Vancouver (Canada), aged 60-75 years, were recruited for a double-blind clinical trial and assigned to either a CHX (n = 550) or a placebo (n = 551) mouth rinse. Subjects alternated between daily rinsing for 1 month, followed by weekly rinsing for 5 months. All sound coronal and root surfaces at baseline were followed annually for up to 5 years. At each follow-up examination, those tooth surfaces with caries, restored, or extracted were scored as 'carious'. The hazard ratio associated with CHX for a sound surface to become filled, decayed, or extracted was 0.87 for coronal surfaces (95% confidence interval: 0.71-1.14, p = 0.20) and 0.91 for root surfaces (95% confidence interval: 0.73-1.14, p = 0.41). These findings suggest that regular rinsing with CHX does not have a substantial effect on the preservation of sound tooth structure in older adults.

OBJECTIVES: This study assessed the knowledge of Indiana dentists and dental hygienists about fluoride's predominant mode of action and their protocols for the use of fluoride for dental caries prevention. METHODS: In 2000, questionnaires were mailed to 6,681 Indiana dentists and hygienists prior to the 2001 release of recommendations for the use of fluoride by the US Centers for Disease Control and Prevention. In 2005, the questionnaires were again sent to Indiana dental professionals to assess changes in knowledge and protocols. In addition, a 10 percent sample of Illinois dentists and hygienists were surveyed to determine the similarity of Indiana and Illinois responses. RESULTS: Questionnaires were anonymously completed and returned. In 2000, a minority of Indiana health professionals (17 percent) correctly identified that remineralization was fluoride's predominant mode of action. There was a significant increase in Indiana respondents correctly identifying this predominant mode of action between 2000 and 2005 (17 percent versus 25 percent, respectively, P < 0.0001). Fourteen percent of Illinois respondents answered correctly in 2005. Preeruptive incorporation of fluoride into enamel was the most frequently cited incorrect response (IN 2000, 79 percent; IN 2005, 71 percent; IL 2005, 82 percent). Some protocols for use of fluoride products reflected inadequate understanding of fluoride's predominant posteruptive mode of action. CONCLUSIONS: The majority of dental professionals surveyed were unaware of the current understanding of fluoride's predominant posteruptive mode of action through remineralization of incipient carious lesions. Additional research is indicated to assess fluoride knowledge and protocols of dental professionals nationwide. Educational efforts are needed to promote the appropriate use of fluoride.

BACKGROUND: Statins have anti-inflammatory and bone stimulating properties that may positively affect chronic periodontitis. Our objective in this study was to evaluate whether statin use by chronic periodontitis patients had a beneficial impact on tooth loss. METHODS: In a retrospective cohort study (N patients = 1,021; mean follow-up = 7.1 years), dental records were merged with pharmacy data. Any statin use during 3 years, statin use during each of 3 consecutive years (regular use), and any statin use during the first 3 years after the initial periodontal exam were evaluated as predictors of tooth loss using negative binomial regression models with adjustment for potential confounding factors. RESULTS: Any statin use during 3 years was not associated with tooth loss rate in the year subsequent to the 3-year period (rate ratio [RR] = 1.00; 95% confidence interval [CI] = 0.56 to 1.81). Regular statin use during 3 years was associated with a non-significant 37% reduced tooth loss rate in the year subsequent to the 3-year period (RR = 0.63; 95% CI = 0.32 to 1.25). Any statin use during the first 3 years after the initial periodontal exam was associated with a 48% decreased tooth loss rate in year 4 and subsequent years (RR = 0.52; 95% CI = 0.29 to 0.95). CONCLUSIONS: Our findings were mixed for an association of statin use with reduced tooth loss in chronic periodontitis patients. Lack of control for some potential confounders, particularly smoking, and evaluation of different patterns of statin usage hamper the interpretation of the results. Exploration of these findings in additional epidemiological studies may be worthwhile.

OBJECTIVES: We used data from the TalaSurvey study to examine associations between dental health experiences, social network characteristics, and levels of behavioral and psychological acculturation in one location in the American Midwest. METHODS: Starting in parishes and community organizations, we identified adults of Mexican origin living in Indianapolis, who were 1st- or 2nd-generation immigrants from Tala, Mexico. Using a social networks methodology and following extensive formative research, we created an egocentric social network survey and administered it via face-to-face interviews. We identified the peers (alters) in interviewees' (egos) personal networks. We asked egos about multiple oral health and dental care variables for self and for alters. Acculturation (psychological and behavioral) was measured with a validated tool. Through logistic and negative binomial regression, we examined the effects of acculturation and network composition on ego's dental insurance status, dental office visits, and the reason for most recent dental office visit. RESULTS: A total of 332 egos (mean age 36; 63% female) were interviewed: 90% were born in Mexico; 45% had completed elementary school or lower; and most had low income. Each ego named 3.9 (SD±1.9) alters in his/her personal network, for a total of 1299 alters (mean age 39; 61% female). Both behavioral acculturation and psychological acculturation were moderately associated with dental insurance coverage, and greater behavioral acculturation predicted more frequent dental care. More psychologically acculturated egos were more likely to seek preventive care. Further, egos with more highly educated networks sought care more frequently and for preventive purposes, net of ego's own education and acculturation. CONCLUSIONS: This study contextualizes acculturation of Mexican Americans within the personal networks in which oral health discussion takes place. The findings underscore the critical importance of acculturation and social network factors in shaping a subgroup of Latinos' orientation toward dental care.

BACKGROUND: The teaching of infection control is gradually being introduced at dental schools in Mexico. However, most practicing dentists have limited access to current infection control standards. Deficiencies of knowledge with regard to blood-borne pathogens such as HIV and hepatitis B virus may influence attitudes toward infected individuals and reduce compliance with infection control recommendations. OBJECTIVE: The purpose of this study was to assess (1) attitudes toward HIV-infected patients and hepatitis B virus-infected patients and (2) infection control knowledge and practices among dental practitioners in Mexico City. METHOD: A total of 196 dentists were interviewed by means of a questionnaire with Likert-type scales and open-ended questions (response rate, 86.1%). RESULTS: Most respondents had no previous social or professional contact with HIV-positive individuals. Nine percent indicated that they had knowingly treated HIV-positive patients. Perceived professional and moral obligations to treat HIV-positive patients were high. Thirty-five percent of the respondents perceived the risk of HIV infection as "considerable" to "very strong." The risk of hepatitis B infection was considered significantly higher than the risk of HIV infection (P <.01); however, 78% of the respondents had not been immunized against hepatitis B. Reported use of personal protective equipment was high. Most respondents used dry heat sterilization. The principal disinfectants used were quaternary ammonium compounds, bleach, and glutaraldehyde. Fifty-four percent of the respondents acknowledged that clinical precautions reduced occupational risks. CONCLUSIONS: This survey revealed contradictory attitudes toward HIV-positive individuals and limited understanding of infection control recommendations. Educational and regulatory efforts are needed to promote better adherence to current infection control standards.
