A survey of oral health status, subjective oral symptoms and oral health behaviors among first-year dental students at a Japanese university

Risk factors or indicators for dental caries and tooth wear and their relative importance in adults according to age

OBJECTIVES

To explore the risk factors for dental caries (DC) and tooth wear (TW) and assess their importance according to age in random French adult patients with >1 partial coronal restoration.

METHODS

The data stem from a prospective observational multicentre cross-sectional study and were collected through interviews and clinical examinations. The study involved 96 dentists from 76 hospital and private clinics and included 822 patients. The data analysed in three age groups (18-29, 30-59, and ≥ 60). Univariate logistic regressions were performed and predictions of DC or TW described using decision trees.

RESULTS

The study confirmed the major influences of oral hygiene, acceptable sugary/acidic beverage consumption and regular dental visits in reducing DC and TW. Further, it exposed age-related risk factors for DC such being a "new patient" and having an "excessive sugary/acidic beverage consumption" in the youngest adults, or "irregular dental visits" in middle-aged adults and in the oldest.

CONCLUSIONS

For appropriate preventive counselling, risk factor assessment should be extensive and age- and dental history-oriented because of unexpected age-related risk factors or risk factor combinations.

CLINICAL SIGNIFICANCE

These results are likely to make better-grounded new recommendations given to young adults since their first visits and throughout their dental clinical pathway.

Oral health knowledge is associated with oral health-related quality of life: a survey of first-year undergraduate students enrolled in an American university

BACKGROUND

Oral health knowledge forms part of oral health literacy that enables individuals to inform appropriate oral health decisions and actions. Oral health-related quality of life (OHRQoL) characterizes self-perception of well-being influenced by oral health. This study aimed to examine the relationship between oral health knowledge and OHRQoL.

METHODS

A random sample of 19-to-24-year-old first-year undergraduate students (n = 372) in Minnesota, United States of America was used. Each student was assessed with an online survey using the Comprehensive Measure of Oral Health Knowledge (CMOHK) and the OHRQoL items of the World Health Organization (WHO) Oral Health Questionnaire for Adults. Relationships between OHRQoL parameters and CMOHK together with other covariates were assessed using ordinal regression models. Associations between OHRQoL parameters were examined with the Kendall's tau-b method.

RESULTS

Dry mouth (45%) was the most reported OHRQoL issue. The respondents showing good oral health knowledge were less likely to experience speech or pronunciation difficulty (β=-1.12, p = 0.0006), interrupted sleep (β=-1.43, p = 0.0040), taking days off (β=-1.71, p = 0.0054), difficulty doing usual activities (β=-2.37, p = 0.0002), or reduced participation in social activities due to dental or oral issues (β=-1.65, p = 0.0078).

CONCLUSIONS

This study suggested a protective effect of better oral health knowledge on specific OHRQoL issues. In addition to provision of affordable dental services, university-wide oral health education can be implemented to improve OHRQoL in undergraduate students.

Association of personality traits with dental visit procrastination by Japanese university students

BACKGROUND

Procrastination is a psychological trait that causes individuals to put off doing things that need to be done. It has recently shown to result in the worsening of symptoms due to delays in seeking medical care. However, it is not clear how perception of dental disease influences dental visits. This study examined the associations of procrastination and personality traits with delayed dental visits for both acute and chronic conditions.

METHODS

Of 599 university students queried, the data of 549 subjects (mean age 19.7 years) were analyzed. A general procrastination scale (GPS), the Big Five personality traits, and oral hygiene habits were used for analysis. The participants were asked about illness awareness conditions related to dental disease, perception of pain in the oral region due to acute oral symptoms and chronic symptoms. The participants were asked the number of days until they decided that treatment was required. Based on the bimodal shape of the distribution, those who answered at least eight days for acute or chronic conditions were classified as the procrastination (P) group and the others as the non-procrastination (Non-P) group.

RESULTS

Significant differences in GPS scores were found between the groups for both acute and chronic conditions, with significant differences in the Big Five traits of extraversion, agreeableness, and neuroticism for an acute condition and extraversion, openness, and neuroticism for a chronic condition. There were no significant differences regarding oral hygiene habits between the groups for either condition. Next, using a Bayesian network, the probabilistic causal relations among procrastination, the Big Five traits, and delays in dental visits for both acute and chronic conditions were analyzed. Among the Big Five traits, conscientiousness and neuroticism were directly related to GPS score. Interestingly, agreeableness was directly related to delays in dental visits only for an acute condition and showed a negative effect, while dental student status had a positive effect on delays in dental visits.

CONCLUSIONS

The results showed that procrastination and dentistry department are factors that directly influence delays in dental visits, while agreeableness, a Big Five trait, has a negative effect on individuals with an acute condition.

Dental caries experience among qat chewers in dental college clinics, Jazan, Saudi Arabia

AIMS

There is a considerable debate on the impact of qat chewing on dental and oral health. Thereby, this study aimed at assessing the dental caries among qat chewers (QC) and non-qat chewers (NQC) who attend outpatient dental clinics, College of Dentistry, Jazan, Saudi Arabia.

MATERIALS AND METHODS

A sample of 100 QC and 100 NQC were recruited amongst those attended dental clinics, college of dentistry, Jazan University during the 2018-2019 academic year. Their dental health was assessed by three pre-calibrated male interns using DMFT index. The Care Index, Restorative Index and Treatment Index were calculated. Comparisons between both subgroups were done using independent t test. Multiple linear regression analyses were further conducted to stand on the independent determinants of the oral health among this population.

RESULTS

QC were unintentionally older (36.55 ± 8.74 years) than NQC (32.96 ± 8.49 years; P = 0.004). Fifty-six percent of QC reported brushing their teeth compared to only 35% (P = 0.001). NQC with university and postgraduate educational levels were more than QC. The mean Decayed [5.91 (5.16)] and DMFT [9.15 (5.87)] were higher among QC compared to NQC [3.73 (3.62) and 6.7 (4.58); P = 0.001 and 0.001, respectively]. The other indices were not different between both subgroups. The multiple linear regression revealed that qat chewing and age, individually or together, as independent determinants for the dental decay, missing, DMFT and TI.

CONCLUSION

Qat chewing habit has a detrimental impact on dental health. It is associated with higher dental caries and missing teeth, and a lower treatment index.
