First-year university students are in a new, independent life situation, which may affect health behaviour, including oral health habits. The aim of this study was to evaluate the association between dental fear and oral health habits, while considering the simultaneous effects of attitude toward food and treatment need at dental check-ups. The data (n = 8514) for this national cross-sectional study were collected from health registers of Finnish Student Health Service. As part of health examination all first-year university students in Finland were sent an electronic questionnaire asking about general, psychological and oral health, and health habits. Dental fear was measured by the question: “How afraid are you of visiting a dentist?” (reply alternatives: “Not at all”, “Somewhat” and “Very”). Chi-square tests and Multiple logistic regression analyses were used to determine the associations between dental fear and oral health habits (tooth brushing, tobacco use, frequency of eating and drinking, eating habits and interval between dental check-ups) as well as attitude to food and treatment need at dental check-ups while controlling for age, gender, general mood and feelings in social situations. Of the oral health habits, tooth brushing and tobacco use were associated with dental fear. Those who brushed their teeth once a day or less often or used tobacco regularly were more likely to have high dental fear than those who brushed their teeth twice a day or more often or used tobacco occasionally or not at all. Students who reported not having a normal attitude to food were more likely to have high dental fear than were those reporting normal attitude to food, but the frequency of eating and drinking was not associated with dental fear. Students who reported needing treatment frequently or at every dental check-up were more likely to have high dental fear than those who reported rarely or never needing treatment. Those students with high dental fear seem to be at risk of having poor oral health habits and abnormal attitude to food, which may increase the risk of deterioration of oral health and the need for treatment. Dental teams should make efforts in helping fearful patients to find motivation for good oral health habits.

Objective. Our objective was to study whether dental condition, measured by numbers of sound, decayed, missing, and restored teeth, was associated with dental fear, and whether age, dental attendance, and/or gender modified this association. Material and Methods. The sample (n=8,028) comprised Finnish adults aged 30 years and older and the study included people (n=6,335) who participated in a home interview and a clinical dental examination. Dental fear was measured by the question: “How afraid are you of visiting a dentist?” Multiple logistic regression analysis was used to determine the association between dental fear and dental condition variables, i.e. numbers of decayed, missing, sound, and restored teeth considering the effects of age, attendance, and gender. Results. With the exception of number of restored teeth, all dental condition variables were associated with dental fear. The association between dental fear and number of decayed teeth was positive and was independent of age, gender, and attendance. Age modified the association between dental fear and number of missing and sound teeth. Among the oldest age group, the numbers of missing and sound teeth were positively associated with dental fear while being negatively associated among the youngest age group. Conclusions. People with high dental fear have poorer dental condition than those with lower fear. Neither gender nor dental attendance affects the association between dental fear and dental condition. The associations between dental fear and numbers of missing and sound teeth vary according to year of birth.

Objective. The aim of our study was to evaluate the association between dental fear and oral health habits (tooth-brushing, use of toothpaste, dental floss and toothpicks, smoking and dental attendance), while simultaneously considering the effect of age, gender, and attained level of education. Material and methods. The nationwide two-stage stratified cluster sample (n=8028) was representative of Finnish adults aged 30 years and older. The response rate was 88%. Dental fear was determined by the question: “How afraid are you of visiting a dentist?” Multiple logistic regression analyses were used to determine the association between dental fear and oral health habits, including age, gender, and attained level of education. Results. Regular smokers were more likely to be very afraid of visiting a dentist than were those who smoked occasionally or not at all. Age modified the effect of dental attendance and tooth-brushing on dental fear. Among 65+-year-olds, those who brushed their teeth less than twice a day were more likely to be very afraid of visiting a dentist than were those who brushed at least twice a day. Irregular attenders were more likely to be very afraid of visiting a dentist than were regular attenders, the effect being strongest among 65+-year-olds. Conclusions. Birth cohort has to be taken into account when associations between dental fear and oral health habits are studied. Dental teams have to be aware of the associations between dental fear and smoking because of the adverse effects of smoking on oral health and the risk of irregular attendance among those with high dental fear.
