Oral health behaviour and its determinants amongst Iranian dental students

Associations between maternal mental health, child dental anxiety, and oral health of 6- to 12-year-olds in Nigeria

Maternal mental health affects their children's oral health. This study assessed the associations between maternal mental health and dental anxiety level, dental caries experience, oral hygiene, and gingival status among 6- to 12-year-old children in Nigeria. This was a cross-sectional study that recruited mother-child dyad participants through a household survey conducted in Ile-Ife, Nigeria. Data collected included the independent (maternal mental health risk, depressive symptoms, and child's dental anxiety), and dependent (caries experience, oral hygiene status, and gingival health status) variables. Multivariate logistic regression analysis was conducted to determine the associations between dependent and independent variables after adjusting for confounders (mothers' age, child's age, sex, and socioeconomic status). Statistical significance was set at p < 0.05. Of the 1411 mothers recruited, 1248 (88.4%) had low mental health risk, and 896 (63.5%) had mild depressive symptoms. As for the children, 53 (3.8%) had caries, 745 (52.8%) had moderate to high dental anxiety, 953 (63.0%) had gingivitis and 36 (2.6%) had poor oral hygiene. The maternal mental health risk was not significantly associated with the child's caries experience (AOR: 1.012; 95%CI: 0.860-1.190; p = 0.886), poor oral hygiene (AOR:1.037; 95%CI: 0.975-1.104; p=0.250), and moderate/severe gingivitis (AOR:0.887; 95%CI: 0.764-1.030; p = 0.115). Maternal depression status was not significantly associated with the child's caries experience (AOR: 0.910; 95%CI: 0.802-1.033; p = 0.145), poor oral hygiene (AOR: 1.016; 95%CI: 0.976-1.057; p = 0.439), and moderate/severe gingivitis (AOR: 0.963; 95%CI: 0.861-1.077; p = 0.509). Maternal mental health risk and depression do not seem to be risk factors for schoolchildren's oral health in Nigeria. Further studies are needed to understand these findings.

Tooth brushing practice in Ethiopia: a systematic review and meta-analysis

Oral hygiene refers to taking care and maintaining the cleanness of gum and teeth; a good oral hygiene practice promotes better oral health in general. Oral hygiene is the top public health concern of the population. Tooth brushing is a technique to keep oral hygiene from related complications. Therefore, this study provides the pooled prevalence of tooth brushing practice in Ethiopia. Databases searched for articles systematically across PubMed, Google Scholar, Hinari, EMBASE, and African Journals Online. Two reviewers independently conducted the selection, screening, reviewing, and data extraction using a Microsoft Excel spreadsheet and used the Joanna Briggs Institute prevalence critical appraisal tools to assess the quality of evidence. All studies conducted in Ethiopia from 2010 to 2020, reporting tooth-brushing practices extracted for and imported into the Comprehensive meta-analysis version 3.0 for further analysis. Beggs and Eggers's tests evaluated for publication bias with Higgins's method evaluated for heterogeneity. A random-effects meta-analysis model with a 95% confidence interval was computed to estimate the pooled effect size (prevalence). Furthermore, the authors employed subgroup analysis based on the study area and sample size. After reviewing 36, 10 articles fulfilled the inclusion criteria, and were included in the meta-analysis. The pooled prevalence of tooth brushing practice was 12.2% (95% CI 7.6-19.2%). The review reported a lower level of tooth-brushing practice in Ethiopia. We recommended that special attention should be given to the oral hygiene of the Ethiopian people.

Assessment of knowledge, attitude and practice of medical and dental students about maintaining and disinfecting toothbrushes

INTRODUCTION

Proper toothbrush care and maintenance play an important role in oral health. This study aimed to investigate the knowledge, attitude and practice of medical and dental students regarding the maintenance and disinfection of toothbrushes.

METHOD

This cross-sectional descriptive study examined 824 medical and dental students of Babol University of Medical Sciences, Babol, Iran. Data were collected using a researcher-made questionnaire and analysed using chi-square test and independent t-test. The level of statistical significance was considered to be <0.05.

RESULTS

Nearly 63.7% of the students had a good level of knowledge regarding toothbrush maintenance, 62.2% had a positive attitude toward toothbrush care, and 53.7% had a good practice. The mean scores of knowledge, attitude, and practice were significantly higher in dental, clinical, and female students as compared to medical, preclinical, and male students, respectively. Based on the results, about 54.3% of the students kept their toothbrushes outside the bathroom; 68% kept them vertically with the bristles upright; and 54% kept them in a separate container. Also, 50.6% of the students believed that toothbrush disinfection was necessary, while 31.9% believed that only certain groups of people needed toothbrush disinfection.

CONCLUSION

This study indicated the moderate level of knowledge, attitude, and practice of medical and dental students in maintaining and disinfecting their toothbrushes. The students' oral health habits were also at a moderate level; therefore, further improvements seem essential. To achieve this goal, educational intervention programs need to be developed in the future.

Is oral rehydration therapy associated with early childhood caries in children resident in Ile-Ife, Osun State, Nigeria?

BACKGROUND

Oral rehydration therapy may increase the risk of early childhood caries (ECC) because of reduced pH in the oral environment.

AIM

To investigate associations between the use of oral rehydration therapy and the prevalence and severity of ECC in children resident in the Ife Central Local Government Area of Osun State, Nigeria.

DESIGN

This observational study assessed the prevalence and severity of caries, using the International Caries Detection and Assessment System (ICDAS) II index. The outcome variables were the prevalence and severity of ECC. The explanatory variable was the use of oral rehydration solution for the management of diarrhea in the 12 months preceding the study. A multivariable logistic regression analysis was conducted to determine associations between the explanatory and outcome variables.

RESULTS

Only 217 (14%) of the 1564 children had used oral rehydration solution for the management of diarrhea. Seventy-three (4.7%) children had ECC. The use of oral rehydration solution was not significantly associated with the prevalence and severity of ECC.

CONCLUSION

The study findings suggest that the use of oral rehydration therapy in the management of diarrhea may not be a risk factor for ECC in communities with low prevalence and severity of ECC and high prevalence of gastroenteritis.

AMELX and ENAM Polymorphisms and Dental Caries

Introduction

The variety of the genetic factors playing role in development of dental caries calls for further research in this regard. The aim of the present study was to investigate the differences between caries-free adults and adults with dental caries in terms of polymorphism of caries-related genes (AMELX and ENAM).

Methods

The present case-control study was performed on 81 adults aged 18-24 years, 41 caries free, and 40 with a DMFT ≥ 4. A questionnaire containing background and demographic information (such as age, gender, time and type of latest dental check-ups, parent's education, oral self-care, and the place of residence in the first 12 years of life) was completed by participants at the time of examination. The blood sample was taken from each participant in the EDTA tube, and PCR was performed. Gene diversity of AMELX and ENAM genes was compared between the two groups.

Results

Regarding AMELX gene, in the caries-free group 33 (80.5%) and in the group with DMFT ≥ 4, 33 (82.5%) students had TT genotype, but this difference was insignificant. For ENAM gene, in the caries-free group 34 (82.9%) and in the group with DMFT ≥ 4, 39 (97.5%) students had TT genotype, but this difference was insignificant (P value = 0.048, CI 95%:0.02-1.27, and OR = 0.145).

Conclusion

There was no relationship between TT and TC genotypes of single nucleotide polymorphism of AMELX and ENAM gene and susceptibility to dental caries, but with increasing sample size, there may be a relationship between SNP of ENAM gene and being caries free.

Risk indicators for dental caries, and gingivitis among 6-11-year-old children in Nigeria: a household-based survey

Background

There is little is known about the factors associated with caries experience and gingivitis among 6–11-year-old children in Nigeria. The aim of the study was to determine the prevalence and preventive oral health behaviors associated with caries and gingivitis among 6–11-year-old children in Nigeria.

Methods

A cross-sectional questionnaire-based survey was conducted in Ile-Ife, Nigeria. The dependent variables were caries and gingivitis. The dmft/DMFT index was used to assess dental caries experience (present or absent) and caries severity. The gingival index was used to assess the prevalence (present or absent) and severity of gingivitis (healthy gingiva/mild gingivitis versus moderate/severe gingivitis). The independent variables were preventive oral health behaviors (frequency of daily tooth brushing, frequency of consumption of refined carbohydrates in-between-meals, use of fluoridated toothpaste, and use of dental floss, history of dental service utilization). A series of logistic regression analysis models were constructed to determine the associations between the dependent and independent variables after adjusting for confounders (age, sex, and socioeconomic status).

Results

There were 69 (5.2%) children with caries. The mean (standard deviation) dmft was 0.08 (0.457) and the mean DMFT was 0.02 (0.159). There were 839 (63.3%) children with gingivitis with a mean (SD) gingival index score of 0.503 (0.453). Children who seldom or never used fluoride toothpaste had significantly higher odds of developing moderate to severe gingivitis (AOR; 1.671; 95% CI: 1.003–2.786; p = 0.049). Children with middle socio-economic status had significantly lower odds of developing moderate to severe gingivitis (AOR: 0.573; 95%CI: 0.330–0.994; p = 0.048). There were no risk indicators identified for caries.

Conclusion

The prevalence of dental caries was low while the prevalence of gingivitis was high in the study population. The daily used of fluoridated toothpaste seem to reduce the risk for moderate/severe gingivitis. Further studies are needed to understand these findings.

Associations between Perceived Self-Efficacy and Oral Health Behaviours in Adolescents

OBJECTIVES

Self-efficacy is a strong health predictor as it affects patients' certainty about their ability to perform recommended behaviours to improve their health. The aim of this study was to examine the associations between perceived self-efficacy and oral health behaviours among adolescents.

METHODS

A convenience sample of adolescents aged 12 to 18 years old were recruited from University of Alberta dental clinic. Demographics, oral health behaviours, self-rated oral health, and task-specific and general self-efficacy were assessed using a questionnaire with three sections. For the comparisons of outcomes across different categories, Student t-test, multivariate regression, and chi-squared tests were used.

RESULTS

Total of 252 adolescents with average (SD) age of 14 (1.7) years participated in the study; 60% were girls; 81% were born in Canada; 56% were White; and 61% had dental coverage. Demographic characteristics had no significant correlation with general self-efficacy. However, correlation coefficients indicated that younger adolescents had higher dietary self-efficacy (negative correlation), girls had higher toothbrushing and dental visit self-efficacy, and those with dental coverage had higher dental visit self-efficacy. A significant association was found between toothbrushing, dietary habits, and dental visits self-efficacy (subscales of task-specific self-efficacy) and their respective outcomes (frequency of toothbrushing, sugar-intake, and regular dentist visits). General self-efficacy was significantly associated with frequency of toothbrushing and participant's self-rated oral health.

CONCLUSION

Higher task-specific and general self-efficacy correlated with better oral health behaviours among adolescents. Therefore, behavioural interventions should be designed to enhance self-efficacy among adolescents in order to improve their oral health outcomes.

Are Iranian graduating dental students prepared to act as future role models of good oral health behaviour? A 10-year study

INTRODUCTION

Dentists by their professional knowledge of prevention have a key role in providing a positive role model for oral health-promoting behaviours. We aimed to investigate the health behaviour of Iranian senior dental students in terms of oral self-care and tobacco use during a 10-year period to assess their preparedness to act as role models for health-promoting behaviours.

MATERIALS AND METHODS

The study was performed in six dental schools selected through stratified cluster random sampling to have a representative sample of all dental schools in Iran. Data were collected in four occasions in 2005, 2008, 2011 and 2015. Senior dental students (N = 1188) were invited to voluntarily complete a self-administered anonymous questionnaire about their oral self-care and tobacco use. Recommended tooth-brushing habit (RTH) was defined as at least twice a day brushing with fluoridated toothpaste. Three separate questions about cigarette, pipe and waterpipe use were applied to assess the students' reported use of tobacco.

RESULTS

The response rate was 81%. Female students reported more frequently RTH than males (p < .001). The reported RTH was more prevalent among nonsmokers. In 2005, 2008, 2011 and 2015, 22.5%, 26%, 28.5% and 24.6% of the students reported smoking, respectively. The trend of reported smoking had the least variation among female students. This was true also for male students regarding RTH.

CONCLUSION

The status and trend of oral self-care and tobacco use among Iranian dental students call for more emphasis on adopting health-promoting behaviours during dental education.

Oral Health Knowledge, Attitude, and Practices among Postgraduate Students of Panjab University, Chandigarh: A Cross-sectional Study

Background

Dental caries and periodontal diseases are the most commonly occurring dental problems. Proper knowledge, attitude, and practices (KAPs) of oral health of young adults will help in prevention of these diseases.

Aim

To comparatively evaluate the oral health KAPs related to oral health of postgraduate students of Panjab University, Chandigarh, with respect to gender and different departments.

Setting and design

A descriptive cross-sectional survey was conducted using a questionnaire that assessed KAPs of postgraduate students, aged 17–25 years.

Materials and methods

This survey was undertaken on 600 postgraduate students of Panjab University, Chandigarh. The sample was divided into 3 groups: group I—arts students (n = 200), group II—science students (n = 200), and group III—commerce students (n = 200). Data were collected and subjected to statistical analysis.

Statistical analysis used

Chi-squared test was used for comparison between different groups. ANOVA and Kruskal–Wallis compared the data between different departments, and Mann–Whitney U test between males and females.

Results

The students of arts had significantly lesser knowledge of oral health compared with other departments. About 65% arts students believed that sweets/soft drinks/chips were causing tooth decay compared with 83% science and 80% commerce students (p value < 0.001). About 52.5% arts students had knowledge that blood on the toothbrush was indicative of gum disease followed by 67% science and 76% commerce students (p value < 0.001).

Conclusion

In our study, there was no significant difference in gender with respect to KAPs of oral health but a significant difference was observed among different departments with arts students showing significantly lesser knowledge.

Association between maternal socioeconomic factors, decision-making status, and dental utilization by children with early childhood caries in sub-urban Nigeria

AIM

To determine the association between maternal education, income, and decision-making status and the presence of early childhood caries (ECC) and dental-service utilization among young children.

METHODS

This cross-sectional study was based on data from a household survey of 1,549 mother-preschool-aged-child dyads conducted in Ife Central Local Government Area, Nigeria. The explanatory variables were maternal education, income, and decision-making status (related to healthcare, large household purchases, and visits to family/relatives). Outcome variables were the presence of ECC and the child's history of dental-service utilization. Poisson regression analyses were conducted to identify factors associated with outcomes; the models were adjusted for maternal age, child's socioeconomic status, oral hygiene status, and frequency of sugar consumption.

RESULTS

The study recruited 1,549 mother-child dyads, of which 66 (4.3 percent) children had ECC, and 90 (5.9 percent) children had a history of dental-service utilization. Fewer than half (42.3 percent) of the mothers earned between N18,001($49.00) and 60,000 ($168.00) per month. Also, 896 (57.8 percent) reported not making any independent decisions, 152 (9.8 percent) made one of three decisions independently, and 313 (20.2 percent) made two or three decisions independently. In the adjusted model, children of mothers with monthly income higher than N60,000 were more likely to have used dental services than were those whose mother's monthly income was less than or equal to N18,000 (adjusted prevalence ratio = 2.29; 95%CI: 1.30-4.02; P = 0.004). No other maternal factor was associated with ECC.

CONCLUSIONS

Although maternal socioeconomic factors and decision-making abilities were not associated with ECC prevalence, more preschool children whose mothers had high income used dental services.

Self-Reported Oral Health Attitudes and Behaviors, and Gingival Status of Dental Students

Aim

The aim of this study was to assess self-reported oral health attitudes and behaviors of the Iraqi dental students and compare the variations in these attitudes and behaviors that linked to dental education level and gender.

Materials and Methods

A self-administered questionnaire depended on the English version of the Hiroshima University Dental Behavioral Inventory (HU-DBI) was prepared, the questionnaire given to 198 dental students.

Results

About 91.4% of the dental students were worried about the teeth colour, and merely minor percentage of them (18.8%) thought it is not crucial to seek dental advice until they acquire a tooth pain; however, 26.3% of the students were disturbed because of their gum colour, and 75.3% of them examined their teeth after brushing. Besides, 72.2% of the students replied that gum disease could not be prevented by tooth brushing only, 60.1% of the students do not give visiting the dentist such concern, and 14.1% of dental students were smokers. The plaque and gingival indices were significantly higher in preclinical students than clinical students.

Conclusion

Iraqi dental students had somewhat good oral health behavior and attitudes; however, extra concentrating is required on the anticipatory and behavioral aspects of oral self-care practices. Female dental students displayed better oral health behavior and attitudes than male colleagues on some issues.

Malnutrition, enamel defects, and early childhood caries in preschool children in a sub-urban Nigeria population

Objectives

The study tried to determine if malnutrition (underweight, stunting, wasting, overweight) and enamel defects (enamel hypoplasia, hypomineralized second molar, amelogenesis imperfecta, fluorosis) were associated with early childhood caries (ECC). The study also examined whether malnutrition was associated with the presence of enamel defects in 0-5-year-old children.

Methods

The study was a secondary analysis of primary data of a cross-sectional study assessing the association between maternal psychosocial health and ECC in sub-urban Nigerian population collected in December 2018 and January 2019. One hundred and fifty nine children were recruited. Exploratory variables were malnutrition and enamel defects. The outcome variables were the prevalence of ECC in 0-2-year-old, 3-5-year-old, and 0-5-year-old children. Multivariable Poisson regression analysis was used to determine the associations, and socioeconomic status, oral hygiene status, and frequency of in-between-meals sugar consumption were adjusted for. The adjusted prevalence ratios, 95% confidence intervals, and p values were calculated.

Results

The prevalence of ECC was 2.1% in 0-2-year-old children and 4.9% in 3-5-year-old children. In adjusted models, underweight, stunting, and wasting/overweight were not significant risk indicators for ECC in either age group. 0-2-year-old children who had amelogenesis imperfecta (p<0.001) and fluorosis (p<0.001) were more likely to have ECC than were children who did not have these lesions. 3-5-year-old children who had hypoplasia (p = 0.004), amelogenesis imperfecta (p<0.001) and fluorosis (p<0.001) were more likely to have ECC than were children who did not have these lesions. 0-5-year-old children with hypoplasia (p<0.001) and fluorosis (p<0.001) were more likely to have ECC than were children who did not have these lesions. There were significant associations between various types of malnutrition and various types of enamel defects.

Conclusion

Although different types of malnutrition were associated with enamel defects, and enamel defects were associated with ECC, malnutrition was not associated with ECC. Further studies are needed to clarify the association between malnutrition and genetically and toxin-induced enamel defects.

Dental health status and oral health behavior among university students from five ASEAN countries

The aim of this study was to investigate dental health status and oral health behavior and associated factors among university students in five ASEAN countries (Indonesia, Malaysia, Myanmar, Thailand and Vietnam). Using anonymous questionnaires, data were collected from 3,344 undergraduate university students (mean age 20.5, SD=1.6; 58.3% female) from five ASEAN countries. Results indicate that 27.7% of students reported to have sometimes, most of the time or always having tooth ache in the past 12 months, 39.4% reported to have one or more cavities, 20.3% did not brush their teeth twice or more times a day, and 30.9% had never been to a dentist (or did not know it). In multivariate logistic regression analysis, older age, living in a lower middle income country, consumption of chocolate or candy, having made a dental care visit, and poor mental health was associated with tooth ache in the past 12 months. Being male, being 20 to 21 years old, coming from a wealthier family background, living in a lower middle income country, frequent consumption of soft drinks, not having consulted with a dentist in the past 12 months and weak beliefs in the benefits of tooth brushing were associated with inadequate tooth brushing frequency ( Collapse

Self-reported Oral Health Behaviour among Scandinavian and Polish Medical Students Studying in Poland

AIM

The aim of the study was to assess the self-reported oral health behaviour of Scandinavian and Polish medical students studying in Poland.

METHODS

Three hundred and fifty subjects took part in the questionnaire survey. They were the 4th to 6th year Scandinavian and Polish medical students attending the same medical school. Test-retest reliability demonstrated an accepted level of kappa > 0.50. The questionnaire comprised issues dealing with demographics, dental health behaviour, fluoride tablet recommendation, self-rated oral health, and smoking habit. Statistical analyses were performed using the Fisher-Freeman-Halton test, Fisher's exact test and the multiple logistic regression. A p value<0.05 was considered significant.

RESULTS

Gender and nationality statistical differences were observed regarding the frequency of visiting a dentist: more Polish females visited a dentist less than a year ago (p=0.011), the reasons for visiting a dentist - check up, filling (p=0.002; p=0.040); the frequency of tooth brushing was higher among Polish females compared to Polish males and Scandinavian females (p<0.001; p<0.001). Polish males ate sweet snacks significantly more often than Polish females and Scandinavian males (p=0.018; p=0.004). In the logistic regression analysis factors were independently associated with visiting a dentist at least once a year: female gender (OR=2.310; 95% CI 1.381-3.865), Polish nationality (OR=3.833; 95% CI 2.293-6.408). Associations with the female gender were significant for the following dependent variables: visiting a dentist more than a year ago (OR=1.913; 95% CI 1.192-3.070), brushing teeth at least once a day (OR=3.759; 95% CI 1.567-9.017), and use of dental floss (OR=2.249; 95% CI 1.445-3.503). Polish nationality was associated with an increasing rate of brushing teeth for at least 3 minutes (OR=2.435; 95% CI 1.526-3.885), and smoking cigarettes (OR=2.340; 95% CI 1.336-4.098).

CONCLUSIONS

Better prognosis for maintaining good oral health was established in the Scandinavian group of students. Polish females took greater care of their teeth than Polish males and the majority of their Scandinavian counterparts.

Knowledge of dental caries and salivary factors related to the disease: influence of the teaching-learning process

Knowledge of factors related to caries and the possible consequences in controlling the disease may show the use of education as a relevant tool for achieving success in terms of dental health maintenance. Therefore, the aim of the present study was to investigate the relationship between acquired knowledge and salivary factors related to dental caries for freshmen students (n = 44) and trainees (n = 32) of the Piracicaba Dental School. Knowledge about dental caries was evaluated by a discursive questionnaire analyzed by the content analysis technique. Salivary flow and pH, buffer capacity, salivary sucrase activity, microbiological counts (total microorganisms, mutans, and lactobacilli) and inorganic concentration of calcium, phosphorus, and fluoride in saliva were evaluated and compared between groups using the Mann-Whitney test, with a significance of 5%. Trainees demonstrated knowledge of the disease, whereas freshmen showed unspecific and confusing concepts. Among the factors analyzed, statistically significant differences were observed for pH, buffer capacity, sucrase activity, total microorganisms, and calcium and fluoride concentrations in saliva. Knowledge about the disease increases and improves over time during the undergraduate program (highest among trainees); although the students from the final year of the program consume more sugar than those from the previous one, they try to balance this activity with greater exposure to fluorides.

Association between knowledge of caries preventive practices, preventive oral health habits of parents and children and caries experience in children resident in sub-urban Nigeria

Background

The objectives of this study were to assess the association between children and parents’ knowledge of caries preventive practices, the parents’ caries preventive oral health behaviours and children’s caries preventive oral health behaviour and caries experience.

Method

Three hundred and twenty four participants aged 8–12 years, 308 fathers and 318 mothers were recruited through a household survey conducted in Suburban Nigeria. A questionnaire was administered to generate information on fathers, mothers and children’s knowledge of caries prevention measures and their oral health behaviour. Clinical examination was conducted on the children to determine their dmft/DMFT. Analysis was conducted to determine the predictors of the children’s good oral health behaviour.

Result

The mothers’ oral health behaviours were significant predictors of the children’s oral health behaviours. Children who had good knowledge of caries prevention measures had significant increased odds of brushing their teeth twice daily or more. The children’s caries prevalence was 13.9%, the mean dmft was 0.2 and the mean DMFT was 0.09. None of the dependent variables could predict the presence of caries in children.

Conclusion

The study highlights the effect of maternal oral health behaviour on the oral health behaviour of children aged 8 years to 12 years in suburban Nigeria. A pilot study is needed to evaluate how enhanced maternal preventive oral health practices can improve the oral health preventive practices of children.

Oral health behaviour and social and health factors in university students from 26 low, middle and high income countries

Poor oral health is still a major burden for populations throughout the world, particularly in developing countries. The aim of this study was investigate oral health behaviour (tooth brushing and dental attendance) and associated factors in low, middle and high income countries. Using anonymous questionnaires, data were collected from 19,560 undergraduate university students (mean age 20.8, SD = 2.8) from 27 universities in 26 countries across Asia, Africa and the Americas. Results indicate that 67.2% of students reported to brush their teeth twice or more times a day, 28.8% about once a day and 4.0% never. Regarding dental check-up visit, 16.3% reported twice a year, 25.6% once a year, 33.9% rarely and 24.3% never. In a multivariate logistic regression analysis, being a male, coming from a wealthy or quite well off family background, living in low income or lower middle income, weak beliefs in the importance of regular tooth brushing, depression and PTSD symptoms, tobacco use and frequent gambling, low physical activity, and low daily meal and snacks frequency were associated with inadequate tooth brushing (<twice daily). Further, being a male, older age, coming from a not well off or poor family background, living in low income or lower middle income, weak beliefs in the importance of regular tooth brushing, PTSD symptoms, illicit drug use, low physical activity, and low daily snacks frequency, skipping breakfast and inadequate fruit and vegetables consumption were associated with less than one annual dental care visit. Oral health behaviour among the students was found to be low. Various risk factors identified can be used to guide interventions to improve oral health behaviour among university students.

Evaluation of gingival bleeding awareness by comparison of self-reports and clinical measurements of freshman dental students

Objective:

The aims of this descriptive, cross-sectional investigation were to evaluate the gingival health awareness of dental students by comparing their clinical gingival bleeding scores and self-reports, and to compare differences in awareness between males and females.

Methods:

In total, 100 (51 males, 49 females) freshman dental students were included in the study. Periodontal indices recorded were: Presence of plaque percentage (plaque index [PI], %), percentage of sites of bleeding on probing (BOP, %), probing depth, and community periodontal index (CPI). Percent agreement, kappa agreement, sensitivity, and specificity were calculated by comparing their self-reported gingival bleeding and BOP%.

Results:

The self-reports of gingival bleeding exhibited statistically significant correlations with BOP% in females (r = 0.42, P = 0.003). Female students showed a higher degree of awareness when kappa agreement, 0.23 (males: 0.16, females: 0.39), sensitivity, 48% (males: 42%, females: 51%), and specificity, 95% (males: 90%, females: 100%) were calculated. Although male dental students had higher PI and CPI scores, there was no significant difference by gender in the clinical measurements.

Conclusions:

According to our results, the validity of self-reported gingival bleeding was higher among dental students than in previous population-based studies. Female dental students showed a higher degree of awareness than males of their gingival health. Half of the included dental students could not differentiate whether they had gingival bleeding when there was actual bleeding. More emphasis should be given to the education of dental students regarding the relationship between gingival bleeding and active periodontal disease.

Evaluating awareness regarding oral hygiene practices and exploring gender differences among patients attending for oral prophylaxis

BACKGROUND

Oral hygiene is intimated in health of all parts of the body including oral cavity. The understanding of actual practices in keeping the oral heath at standard based on patient's perceptions of oral health care is vital. Understanding the effect of gender on oral health would facilitate the development of successful attitude and behavior modification approach towards sustainable oral health.

PURPOSE OF STUDY

To evaluate awareness regarding oral hygiene practices and exploring gender differences among patients attending for oral prophylaxis.

MATERIALS AND METHODS

A survey was conducted among 250 patients attending the department of periodontology, Maulana Azad institute of dental sciences for oral prophylaxis. A structured questionnaire was used to collect information regarding practices and perception about oral hygiene.

RESULTS

Majority of the patients (60.4%) felt that oral hygiene is mandatory for overall health of the body. The use of toothpaste and toothbrush (83.6%) was the most preferred cleaning aid among the study population in the present study. The major constraint for avoiding dental examination was no felt need (41.2%) followed by cost of dental treatment (26.8%) and time constraints (24.0%).

CONCLUSIONS

Professional plaque removal and regular follow-up combined with oral hygiene instructions to the patients can minimize the level of gingival inflammation and swelling. The poor resources for dental care, common malpractices and nonavailability of professional care are the main barriers in seeking optimum oral hygiene.

Preventive oral health practices of school pupils in Southern Nigeria

Background

One of the goals of the World Health Organisation goal is to ensure increased uptake of preventive oral self-care by 2020. This would require the design public health programmes that will ensure children place premium on preventive oral health care uptake. One effort in that direction is the need for countries to define baseline measures on use of preventive oral self-care measures by their population as well as identify factors that impact on its use. This study aims to determine the prevalence and the impact of age and sex on the use of recommended oral self-care measures by pupils in Southern Nigeria.

Methods

Pupils age 8 to 16 years (N = 2,676) in two urban sites in Southern Nigeria completed a questionnaire about recommended oral self-care (use of fluoridated toothpaste, flossing, regularity of consuming sugary snacks between main meals), time of the last dental check-up and cigarette smoking habit. Chi square was used to test association between age (8-10years, 11–16 years), sex, and use of recommended oral self-care. Logistic regression analysis was used to determine the predictors of use of recommended oral self-care.

Results

Only 7.8% of the study population practiced the recommended oral self-care. Older adolescents had an 8.0% increased odds (OR: 1.08; CI:0.81–1.43; p = 0.61) and males had a 20.0% decreased odds (OR: 0.80; CI:0.60-1.06; p = 0.12) of practicing recommended oral self-care though observed differences were not statistically significant. Very few respondents (12.7%) had visited the dental clinic for a check-up in the last one year. Majority of the respondents (92.2%) were non-smokers.

Conclusions

The use of a combination of oral self-care approaches was very low for this study population. Age and sex were predictive factors for the use of components of the oral self-care measures but not significant predictors of use of recommended oral self-care. Future studies would be required to understand ‘why’ and ‘how’ age and sex impacts on the use of caries preventive oral self-care measures to be able to design effective prevention educational programmes for the study population.

Do dentists have better oral health compared to general population: a study on oral health status and oral health behavior in Kathmandu, Nepal

Background

Dentists are considered role models by the general population in regards to oral hygiene and oral health behavior. This study aimed to access the oral health status of dentists and laypersons, and compare the dentists’ practice of preventive dentistry and oral self-care behaviors to that of the laypersons.

Methods

This cross-sectional study recruited 472 participants (195 dentists and 277 laypersons from the general population). Their oral health/hygiene behavior was assessed using a standardized close-ended multiple choice questionnaire. Oral examination was performed to assess caries using Decayed Missed Filled teeth (DMFT) index and periodontal status using Community Periodontal Index of Treatment Needs (CPITN).

Results

Ninety-six percent of dentists brushed their teeth at least once daily, using fluoridated toothpaste and 80.5% twice daily. Although 94% of laypersons brushed their teeth once daily, they seldom used fluoridated toothpaste. Ten percent of participants in each group were caries free. The mean number of teeth present in the oral cavity (27.4 versus 25.4), mean number of teeth with caries (1.8 versus 3.7) and fillings (2.5 versus 0.4) were significantly different (p < 0.0001) between dentists and laypersons, respectively. Regarding the periodontal status, 82% of dentists had CPITN score of 0 whereas 71% of laypersons had the highest score 3 (p = 0.007), and 81% of the laypersons reported tooth mobility compared to 1% of dentists (p < 0.0001).

Conclusions

The participating dentists had better periodontal status and better self-reported oral health behaviors than the laypersons. Despite similar prevalence of caries in the two groups, the prevalence of decayed and unfilled teeth was lower among the dentists.

Determinants of preventive dental practice for children among final-year dental students in Nigeria

BACKGROUND

This study aims to identify the determinants of caries prevention-oriented practice for children among final-year dental students in Nigeria.

METHOD

A questionnaire was distributed to 179 final-year dental students in six dental schools in Nigeria. It requested information on age, gender, knowledge of caries prevention measures, self-perceived competency in providing caries-preventive care for children, and caries prevention-oriented practice for two hypothetical cases with high and low risk of caries. Chi-squares tests and logistic regression analysis were done.

RESULTS

Between 24% and 41% of the respondents indicated their inability to determine the appropriate treatment modality for children with high and low caries risk. Majority of the students failed to differentiate between the caries-preventive practice for children with high and low risk of caries: preventive strategies for children with high caries risk were also used for those with low caries risk. Age, gender, knowledge of caries prevention measures, and self-perceived competency in providing caries-preventive care were not associated with student's capacity to provide caries-preventive practice for children.

CONCLUSION

Caries-preventive practice among dental students in Nigeria could be improved. It may be important to explore the possible role of problem-based learning approach in addressing this challenge.

Determinants of preventive oral health behaviour among senior dental students in Nigeria

BACKGROUND

To study the association between oral health behaviour of senior dental students in Nigeria and their gender, age, knowledge of preventive care, and attitudes towards preventive dentistry.

METHODS

Questionnaires were administered to 179 senior dental students in the six dental schools in Nigeria. The questionnaire obtained information on age, gender, oral self-care, knowledge of preventive dental care and attitudes towards preventive dentistry. Attending a dental clinic for check-up by a dentist or a classmate within the last year was defined as preventive care use. Students who performed oral self-care and attended dental clinic for check-ups were noted to have complied with recommended oral self-care. Chi-square test and binary logistic regression models were used for statistical analyses.

RESULTS

More male respondents agreed that the use of fluoride toothpaste was more important than the tooth brushing technique for caries prevention (P < 0.001). While the use of dental floss was very low (7.3%), more females were more likely to report using dental floss (p=0.03). Older students were also more likely to comply with recommended oral self-care (p<0.001). In binary regression models, respondents who were younger (p=0.04) and those with higher knowledge of preventive dental care (p=0.008) were more likely to consume sugary snacks less than once a day.

CONCLUSION

Gender differences in the awareness of the superiority of using fluoridated toothpaste over brushing in caries prevention; and in the use of dental floss were observed. While older students were more likely to comply with recommended oral self-care measures, younger students with good knowledge of preventive dental care were more likely to consume sugary snacks less than once a day.

Oral health behavior of drug addicts in withdrawal treatment

Background

Oral 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.

Methods

Through 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.

Results

Of 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).

Conclusion

Poor 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.

Oral health attitudes and behaviours of final-year dental students

OBJECTIVES

The objectives of this study of final-year dental students in 10 classes (1997, 2001-2009) were to examine their self-reported oral health attitudes and behaviours and describe any trends in these attributes.

PARTICIPANTS AND METHODS

Students were surveyed in final semester via an anonymous questionnaire (34 behaviour questions; eight attitude statements). Distributions, trends over time and attitude-behaviour associations were examined.

RESULTS

Of 583 students, 459 responded (79%). All tooth-brushed with fluoride toothpaste; 80% brushed ≥2/day. Overall, 85% flossed; over time flossing behaviour increased significantly (P < 0.05), and those flossing 1-2/day increased (P < 0.005). Over time, significant decreases occurred in those taught toothbrushing (P < 0.001) and flossing (P < 0.05), and in use of mouth rinses (P < 0.05) and tooth cleansing sticks/picks (P < 0.001). Almost all (96%) had received a dental examination; 77% attended a dentist 1-3/year. Between-meal snacking was common (84%); 71% chewed gum. Although 18% had ever smoked, 5% currently smoked. Most strongly agreed they expected to keep most of their teeth for all their life (76%); their future needs for fillings would be minimal (61%); smoking could adversely affect their teeth or gums (85%); and regular dental attendance was important for their dental health (51%). Congruent attitudes and behaviours favouring oral health were widely held concerning dental attendance, flossing and smoking.

CONCLUSIONS

Final-year dental students showed well established, favourable oral hygiene attitudes and behaviours, with evidence to suggest this knowledge was developed whilst in dental school. Despite many ceasing smoking, 5% still smoked. All dental students should receive training in motivational counselling and tobacco cessation to ensure this is included in patient care.

Major differences in oral health knowledge and behavior in a group of Iranian pre-university students: a cross-sectional study

To establish efficient methods for self-prevention of oral diseases, assessment of dental health behavior and knowledge in various social classes is necessary. The main purpose of this study was to determine the major differences in oral health knowledge and behavior in a group of Iranian pre-university students. In this cross-sectional study, 591 pre-university students from different regions of Mashhad, Iran were randomly selected to complete a questionnaire consisting of two parts including dental health behavior and knowledge. Scores were recorded and statistical analyses performed to determine the correlation between dental health behavior and knowledge. Data was analyzed with Student's t-test, one-way analysis of variance and Pearson correlation. The mean score of dental health knowledge was significantly lower than the dental health behavior (2.95 ± 0.02 vs. 3.31 ± 0.05, P < 0.001). This difference was observed with gender, birth location and major subject of study. The dental health behavior of Iranian pre-university students was inadequate and their dental health knowledge was at a lower level compared to their behavior. Experimental science students had better oral health behavior compared to other students.

A comparative study of oral health knowledge, attitude and behaviour of non-medical, para-medical and medical students in Udaipur city, Rajasthan, India

AIM

The aim of the study was to assess and compare the Oral health knowledge, attitude and behaviour of the non-medical, para-medical and medical students.

MATERIAL AND METHODS

In a cross-sectional study, a total of 825 students (males - 577, females - 248) of six different professions belonging to non-medical, para-medical and medical categories were surveyed using a self-administered, structured questionnaire pretested through a pilot survey. The mean percentage scores, standard deviation and frequency distribution were calculated. The Student's t-test, anova test, Scheffe's test and chi-squared test were used as test of significance. The linear regression analysis was used to assess the relation of behaviour with knowledge and attitude.

RESULTS

The knowledge scores were significantly higher for the medical students compared with those of non-medical students. The attitude scores were significantly lower for the non-medical category compared with the other two categories and the scores were the highest among the para-medical students. The behaviour scores were significantly lower for the non-medical students than for the para-medical and the medical categories. All the scores were significantly higher for females than for the males. Regression analysis showed a linear relationship of behaviour with the attitude, but no significant linear relation with the knowledge.

CONCLUSION

All the students showed low level of knowledge and the preventive behaviour among the students could still be improved. The results indicate that the knowledge was not enough to influence the oral health behaviour, but behaviour showed linear relationship with attitude of the students.

Tooth brushing, tongue cleaning and snacking behaviour of dental technology and therapist students

Objective

To determine the tooth brushing, tongue cleaning and snacking behaviour of dental technology and therapist students.

Methods

A descriptive cross-sectional study of students of Federal School of Dental Therapy and Technology Enugu, Nigeria. Self-administered questionnaire was used to obtain information on demography, frequency, duration and technique of tooth brushing and tongue cleaning as well as information on consumption of snacks.

Results

A total of 242 students responded. Dental technology students made up 52.5% of the respondents and dental therapist in training made up 47.5%. Majority (63.2%) of the respondents considered the strength of tooth brush when purchasing a tooth brush and 78.9% use tooth brushes with medium strength. Seven-tenth (71.9%) of the respondents brush their teeth twice daily and 52.1% brush for 3–5 minutes. About one-third (30.2%) brush their teeth in front of a mirror. Chewing stick was used by 51.7% of respondents in addition to the use of tooth brush. Tongue cleaning was done by 94.2% with only 9.5% using a tongue cleaner. Only 20.2% reported regular snacks consumption. Nine-tenth (90.4%) of respondents were previously involved in educating others, apart from their colleagues, on tooth brushing.

Conclusion

This survey revealed that most of the dental therapy and technology students had satisfactory tooth-brushing behaviour. The zeal to educate others about proper tooth brushing revealed in this study suggests that the students may be helpful in oral health promotion.

A comparative study of oral health knowledge, attitude and behaviour of first and final year dental students of Udaipur city, Rajasthan, India

OBJECTIVE

To assess and compare differences in oral health knowledge, attitudes and behaviour among first and final year dental students in Udaipur city, Rajasthan, India.

MATERIALS AND METHODS

In a cross-sectional study, 182 first year students (59 males and 123 females) and 157 final year students (75 males and 82 females) of the two dental colleges in Udaipur city; Rajasthan, were surveyed using a self-administered structured questionnaire including 37 multiple choice questions pretested through a pilot survey. The data was analysed using the spss version 10.0. The mean percentage scores, standard deviation and frequency distribution were calculated. The Student's t-test and anova test were used as test of significance. The linear regression analysis were used to assess the relation of knowledge, attitude and behaviour.

RESULTS

The mean % score for oral health knowledge, attitude and behaviour were significantly higher in final year students compared to first year students (P < 0.001). The linear regression analysis showed a statistically significant linear relationship of attitude with the knowledge (P < 0.001) and behaviour with the attitude (P < 0.001) of the students.

CONCLUSION

Besides the positive changes revealed in the oral health knowledge, attitude and behaviour, among the students from first to final year of dental studies, preventive behaviour among the students could still be improved.
