Early childhood caries (ECC) remains a serious problem in several developing and developed countries. This cluster randomised trial evaluated the impact of a 6-month educational intervention on ECC. The trial targeted 12- to 15-month-old children (n = 242) and their mothers in Tehran, Iran, visiting 18 public health centres, randomly selected and assigned to two intervention groups and one control group. At baseline, each mother was interviewed and each child underwent a dental examination of all teeth for the number of decayed teeth (dt) and of upper central incisors for the number of teeth with enamel caries (de). All mothers in the two intervention groups (A and B) received oral health instructions from the vaccination staff. In addition, group A received extra reminders. The outcome was defined as increments in the number of teeth with dt or de, as percentages of children developing new dt or de, and as the number needed to treat (NNT). No new de appeared in group A, the mean de increment in group B was 0.2 (SD = 0.6), and in the controls, it was 0.4 (SD = 0.7) (p < 0.05). The percentages of children developing new de were 0, 14, and 26%, respectively. No differences in dt increments were found. Regarding de, NNT for group A was 4 and for B 9; the figures for dt were 13 and 17, respectively. In conclusion, oral health education given to mothers by general health staff is a valuable tool to prevent caries in infants and toddlers.

BackgroundIntegration of oral health promotion into general health care has been highly recommended by the World Health Organization. Primary-care physicians can as part of their general health care promote and contribute to improved oral health care. Our aim was to investigate primary-care physicians’ knowledge of oral health, their attitudes toward delivering oral health care (OHC), and their willingness to obtain more education in this field.MethodsWe conducted a cross-sectional survey of all primary-care physicians working in the public health centers of Tehran city. An anonymous self-administered questionnaire queried their knowledge in pediatric- and general medicine-related areas of dentistry, providing knowledge scores to be calculated for three domains. The physicians’ attitudes toward OHC and willingness to pursue continuous education underwent evaluation with statements utilizing a 5-point Likert scale. Totally, 220 physicians took part in the survey (response rate: 92%). Chi-square test, linear and logistic regression, and t-test served for statistical analyses.ResultsThe physicians’ knowledge score was significantly lower in the pediatric domain than in the dental and medical domains (p < 0.001). The number of physicians answering correctly to the pediatric questions was less than 40%. Almost all physicians (95%) reported it necessary for a physician to know about OHC and admitted (78%) that physicians’ general knowledge in this field is inadequate. Further, 77% of the physicians expressed a will to implement preventive oral health activities in their practice, and almost two-thirds (62%) of them showed a willingness to pursue further education about OHC. Those with higher knowledge scores had a greater willingness to deliver oral health care to their patients.ConclusionsPhysicians’ lack of knowledge of OHC and their generally positive attitudes toward it revealed a great need for planning of a continuous medical education program in primary care.

On account of its association with ECC, milk-bottle feeding at night should be limited, whereas prolonged breastfeeding appears to have no such negative dental consequences.

To improve oral hygiene in early childhood, more emphasis should be placed on mothers' own toothbrushing and their skills in their children's oral cleaning.

BackgroundOral health behavior (OHB), one major factor contributing to proper oral health status, has been addressed insufficiently in addiction literature. The aim of our study was to investigate OHB and its determinants among drug addicts in withdrawal treatment.MethodsThrough a stratified cluster sampling method, we collected the data from 685 patients in withdrawal treatment in Tehran using self-administered questionnaires on OHB components and conducting interviews about patients’ characteristics and addiction history. The T-test, ANOVA, and a linear regression model served for statistical analysis.ResultsOf the patients, 48% reported brushing their teeth less than once a day, more than 90% used fluoride toothpaste almost or always, and 81% flossed their teeth rarely or never. Eating sugary products twice a day or more was reported by 57% of the patients and 85% of them were current smokers. Poor OHB was associated with male gender, lower education, being addicted mainly to crystalline heroin, starting drug abuse at a younger age, and having a longer history of addiction (p < .05).ConclusionPoor OHB was found among the participants in drug withdrawal treatment. Preventive strategies on oral health should be planned and be integrated into other health promotion programs for addicts along with their withdrawal treatment taking into account special groups at higher risk.

Objectives: This case-control study aimed to compare patients with temporomandibular disorders (TMD) and healthy controls in terms of oral health-related quality of life (OHRQoL) considering Graded Chronic Pain Scale (GCPS) scores, pain duration, psychological impairment and demographic characteristics.Methods: A total of 75 patients with TMD and 75 healthy controls were recruited. The short version of Oral Health Impact Profile (OHIP-14) was administered for evaluating the OHRQoL. Psychosocial impairments were assessed using the General Health Questionnaire-28 (GHQ-28). The Research Diagnostic Criteria for TemporomandibularDisorders (RDC/TMD) axis I and II were also used for patient diagnosis and collecting GCPS scores, pain duration, age and gender. Independent-sample t tests, Pearson's chi-square tests and multiple logistic and linear regression models were applied for statistical analysis. Results:The mean age of the patients was 34.3±12.4 years. A female-to-male ratio of 6:1 was seen in the TMD group. The prevalence and severity of the OHIP were significantly different between the TMD and control groups (66.7% vs 12.0% and 18.0 vs 9.2, respectively). According to multiple logistic regression for OHIP prevalence and multiple linear regression for OHIP severity in the TMD group, GCPS scores and pain duration, followed by psychological impairment, were the most important predictors of the OHRQoL. Conclusion:TMD negatively affected the OHRQoL, particularly in patients with psychological impairments. Meanwhile, age and gender did not seem to have a serious effect. Hence, promoting the quality of life of patients with TMD requires emphasis on chronic pain management and maintaining good mental health.

BackgroundThe majority of young children receive no early dental examination while attending primary health care for routine check-ups. Our aim was to study primary care nurses’ knowledge of oral health care (OHC) and their attitudes toward delivering OHC, as well as to assess their willingness to obtain OHC information.MethodsWe conducted a cross-sectional survey of all primary-care nurses working in the public health centres of Tehran city. An anonymous self-administered questionnaire queried their knowledge in paediatric-, general and medicine-related areas of dentistry, providing knowledge scores for three domains. The nurses’ attitudes toward OHC and their willingness to obtain OHC information underwent evaluation with statements utilizing a five-point Likert scale. Altogether 680 nurses took part in the survey. The Chi-square test, t-test, one-way ANOVA and logistic regression model served for statistical analyses.ResultThe mean score for the paediatric dentistry domain (3.6, SD: 1.5) was lower than for the medical (4.4, SD: 2.3) and dental domains (5.8, SD: 1.5). Obtaining higher scores in the paediatric (OR = 1.2) and dental (OR = 1.3) domains, and a greater willingness to receive OHC information (OR = 5.3), were associated with a positive attitude toward OHC. Nurses with a lower education (OR = 1.9) and better oral health behaviour (OR = 1.1) as well as those working in a non-affluent region (OR = 1.6) had a more positive attitude toward OHC.ConclusionPrimary care nurses’ low level of knowledge in OHC and their positive attitude and willingness to obtain more information point to the need for appropriate OHC training and encouragement for the nurses to promote oral health and prevent dental diseases.
