Factors associated with dental anxiety among older people in Britain

Effects of dental anxiety and anesthesia on vital signs during tooth extraction

BACKGROUND

Anxiety is common preceding tooth extraction; hence, it is crucial to identify patients with dental anxiety (DA) and to manage DA. This study assessed the level of DA and influencing factors in tooth extraction patients in a dental hospital in China and changes in their blood pressure (BP) and heart rate (HR) during the tooth-extraction procedure.

METHODS

The study was a cohort study. The Dental Anxiety Scale (DAS) was used to assess the level of DA of 120 patients before tooth extraction. A Demographics and Oral Health Self-Assessment Form was used to assess factors influencing DA. The correlations of DAS scores with HR and BP were measured. The effects of local anesthesia and general anesthesia on HR and BP were also compared using a Datex-Ohmeda anesthesia monitor to detect HR and BP continuously before and after anesthesia. Independent sample t-tests, OLS multiple regression model and one-way analysis of variance were applied to analysis the results.

RESULTS

Based on the DAS score, 12.5% of the participants were identified as suffering from DA. DA was related to age, gender, and the self-assessment of oral health. The DAS score was correlated with increased BP (P < 0.05). BP showed an overall upward trend after local anesthesia, while it was generally stable after general anesthesia. The systolic BP at 4 and 5 min and the HR at 2 and 4 min increased remarkably (P < 0.05) after local anesthesia compared with those before anesthesia. The HR and BP of patients under local anesthesia were generally higher than those of patients under general anesthesia were during the operation.

CONCLUSIONS

The prevalence of DA in adults was 12.5% in this study population. DA was related to gender, age, and the self-assessment of oral health. The score of DAS was correlated with BP. Compare to local anesthesia, general anesthesia can make the vital signs of tooth extraction patients more stable.

Patient perceptions and experiences of dental fear of different dental specialties: a mixed-method study

OBJECTIVE

The primary objective of this study was to validate an Urdu translation of Kleinknecht's Dental Fear Survey (DFS) for use in Pakistan and to explore which items contribute the most to the variance in dental fear scores based on patient perceptions and lived experiences during dental care.

METHODOLOGY

This mixed-method study was conducted at Dow Dental Hospital from February 2022 to June 2022. For quantitative analysis, a total of 273 participants were enrolled through convenience sampling. After obtaining signed consent, participants were asked to self-report their dental fear. In-depth interviews with 25 patients displaying moderate to high dental fear were conducted to clarify the elements of dental fear scores through the lens of individual perceptions and experiences.

RESULTS

The prevalence of moderate dental fear was significantly higher among female participants than males. The mean dental fear score was higher among females (39.47 ± 14.23) as compared to males (30.83 ± 10.50). Most of the female participants reported an increase in breathing rate and heartbeat during dental treatment. The highest mean fear score was reported by participants who underwent oral surgical treatment (42.98 ± 14.21), followed by participants who received restorative care (36.20 ± 12.60). Approaching the dentist's office was the significant factor that contributed the most to the variance in dental fear scores. Four themes were generated through the content analysis of the interviews: physical reactions to dental procedures, perceptions and fears about surgical and restorative procedures, and gender and environmental factors in dental fear and interaction with dentists.

CONCLUSION

The Urdu translation of DFS is a reliable and valid instrument for assessing dental fears in Pakistan based on the findings of this study. Patients perceive surgical and restorative procedures as unpleasant and threatening. It was noted that "the heart beats faster" and "the breathing rate increases." were the top two physiological responses.

Estimated prevalence of dental fear in adults: A systematic review and meta-analysis

OBJECTIVES

To systematically review the literature about: 'What is the global estimated prevalence of dental fear in adults?'.

DATA/SOURCES

Inclusion criteria were observational population-based studies reporting the prevalence or raw data of dental fear in adults (>18 years). Five electronic databases (Embase, PubMed, Scopus, Virtual Health Library and Web of Science) were searched without language restrictions up to March 2020. Two researchers independently performed the study selection, data extraction and quality assessment of the included studies. Risk of bias was performed using the Joanna Briggs Critical Appraisal Checklist for Prevalence and Incidence studies. The prevalence pooled estimates of dental fear were calculated using fixed- and random-effect models. Subgroup analyses were performed.

STUDY SELECTION

The search strategy identified 4,486 studies. After removal of duplicates (1,722), title and abstract screening (2,764) and full-text reading (108), 31 publications were deemed eligible for this systematic review. Three studies presented low risk of bias and 28 studies presented high risk of bias. A total of 72,577 individuals 18 years of age or older composed the sample of this systematic review. The global estimated prevalence of dental fear and anxiety (DFA), high DFA and severe DFA in adults were 15.3 % (95 %CI 10.2-21.2), 12.4 % (95 %CI 9.5-15.6) and 3.3 % (95 %CI 0.9-7.1), respectively. Subgroup analyses showed a higher prevalence of DFA, high DFA and severe DFA among women and younger adults. The instruments used to measure dental fear also affected its prevalence.

CONCLUSIONS

Dental fear and high dental fear are prevalent in adults worldwide, being more prevalent among women.

CLINICAL SIGNIFICANCE

Evidence suggests fear negatively impacts dental care pattern, clinical and subjective oral health conditions. A better knowledge of the global prevalence and the factors associated with this problem will allow that prevention or even behavior modulation strategies of the fearful individual's in dental setting being carried out.

The relationship between subjective oral health and dental fear in Korean adolescents

Background

This study is aimed to evaluate the level of fear and to reduce the overall fear, thereby enabling patients to receive treatment via timely visits.

Methods

In a survey conducted by 460 South Korean middle school students, we used 453 data that faithfully responded to the survey. Multiple regression analysis was conducted to investigate the factors influencing subjective oral health and dental fear. The significance level used for statistical significance was α = 0.05.

Results

The level of fear was higher for upper grade, female students. The factors affecting dental fear were higher for gingival bleeding and dental pain. Regarding factors for dental fear affecting subjective oral health, lower fear of puncture needle and tooth removal tool resulted in higher subjective oral health.

Conclusion

The study found that adolescents had higher fear of dental care when they had gingival bleeding and tooth pain. Gingival bleeding is a symptom of early gingival disease and dental pain is likely due to advanced dental caries. These results suggested that it is necessary to have a program to reduce dental fear and anxiety as well as a program to prevent dental diseases through regular periodic screening and education.

Is there a relation between dental anxiety, fear and general psychological status?

Background

Dental anxiety is a widespread problem in many populations. This problem can be a barrier to dental care and may lead to poor oral health. Dental anxiety may be related to psychological status.

Aims

The aim of the present study was to assess the levels of dental anxiety, dental fear, Beck Depression, and state-trait anxiety according to age, gender and education level in patients at the periodontology clinic in the Diyarbakır Mouth and Dental Health Center.

Study Design

A total of 231 patients (115 males, 116 females) filled out dental fear scale (DFS), dental anxiety scale (DAS), Beck Depression Inventory (BDI), state-trait anxiety inventory-state (STAI-S), and state-trait anxiety inventory–trait (STAI-T) questionnaires, and evaluations of DFS, DAS, BDI, STAI-S, and STAI-T were conducted according to age, gender, and education level.

Results

The mean DFS, DAS, BDI, STAI-T, and STAI –S were 45.64, 9.15, 13.16, 38.90, and 40.18, respectively. There was a significant association among DFS, DAS, BDI, STAI-S, and STAI-T (p < 0.05). These surveys scores were significantly higher in females than males (p < 0.05). The results of this study indicated that gender age and education level have important effects on DFS, DAS, BDI, STAI-S, and STAI-T (p < 0.05).

Conclusion

Dental anxiety and dental fear were found to be related to psychological status (BDI, STAI-S, and STAI-T) over time. There are some patients with unaddressed psychological distress.

Evaluating the Relationship of Dental Fear with Dental Health Status and Awareness

INTRODUCTION

Dental fear is one of the most common problems in dentistry, for both the patient and for the dentist. This issue can have an important effect on an individual's dental health.

AIM

The aim of this paper was to report on the prevalence of dental anxiety and to explore if high levels of anxiety are associated with sociodemographic factors, oral health status, and level of oral health awareness.

MATERIALS AND METHODS

The sample for this cross-sectional study included 294 patients (154 males and 140 females). All participants filled out a Dental Fear Survey (DFS) to evaluate their level of dental fear. Gender, age, education level, socioeconomic status and oral health awareness were also noted. Oral health behaviors and oral health awareness levels were investigated using seven questions. Also, the periodontal status of all participants was evaluated using the Community Periodontal Index of Treatment Needs (CPITN). Differences between different subgroups were tested using the chi-square test.

RESULTS

There was a statistically significant difference between the DFS groups with regard to sociodemographic data. Women had significantly higher scores than men, and young patients had significantly higher scores than others. Patients with low education levels and low socioeconomic status had high DFS scores. Periodontal status was better in groups that had scores in the low and moderate ranges compared to groups that had high scores on the DFS. There was a statistically significant difference between the groups of DFS and CPITN (p<0.05). Patients with low and moderate levels of DFS answered the oral health knowledge questions correctly. There was a statistically significant difference between the DFS groups based on correct answers to the oral health knowledge questions (p<0.05).

CONCLUSION

The elimination of dental fear is very important and should be treated according to a patient-centered assessment. These individuals were informed about the dental treatment procedure so their prejudices were eliminated. Patients with a high level of dental fear may be given psychiatric support for comfortable treatment procedure.

Dental fear and its possible relationship with periodontal status in Chinese adults: a preliminary study

BACKGROUND

The aim of the present study was to describe the characteristics of dental fear of Chinese adult patients with periodontal disease and provide information for clinical assessment.

METHODS

A total of 1203 dental patients completed questionnaires that included Corach's Dental Anxiety Scales (DAS), Dental Fear Survey (DFS) and the short-form Dental Anxiety Inventory (S-DAI). Among all the patients, 366 cases were self-reported periodontal disease. The general characteristics were described, such as socio-demographics, dental attendances and oral health behaviors. The statistical analysis was performed by t-test, Mann-Whitney U test and linear regression respectively to evaluate correlations between dental fear and general characteristics according to the three scales.

RESULTS

The prevalence of dental fear was 74% among 1203 patients, 23.4% of total with high dental fear, while 27.3% in the patients with periodontal disease. The average score of DAS and DFS for patients with periodontal disease was significantly higher than those without periodontal disease. The regression analysis indicated that gender, age, periodontal status, dental attendances and oral health behaviors were correlated with dental fear. Among 366 patients with periodontal disease, gender, dental attendances and oral health behaviors had correlation with dental fear. The analysis of DFS scale exhibited that 'drilling with handpiece' and 'injecting the anesthetic' were the most important factors to contribute to dental fear.

CONCLUSIONS

There was high prevalence of dental fear in Chinese adult patients, particularly in patients with periodontal disease, and high level of dental fear may lead to poor periodontal status.

Prevalence of dental anxiety and its relation to age and gender in coastal Andhra (Visakhapatnam) population, India

Background:

Dental fear, anxiety and phobia have consistently been reported as widespread problems that persist despite the technological advances that have made dentistry less painful and less uncomfortable. The aim of this study was to assess the prevalence of dental anxiety (DA) and its relation to age and sex among Coastal Andhra (Visakhapatnam) population.

Materials and Methods:

A randomized controlled study was designed among 340 individuals at GITAM Dental College and Hospital, Visakhapatnam. The sample for the study consisted of 180 female and 160 male subjects between 15 and 65 years of age; all were supplied with two questionnaires (Corah DA scale [CDAS] and Clarke and Rustvold dental concerns assessment scale describing anxiety provoking stimuli. The Mann-Whitney U-test and the Kruskal-Wallis test were applied (significance level P < 0.05). The correlations between the two questionnaires were calculated using the Spearman's rank correlation coefficient.

Results:

Two questionnaires were collected from all 340 individuals and the Indian translation of both instruments was found to be internally reliable with a Cronbach's alpha of 0.093. Overall prevalence of DA was high (77.4%) but severe (22.6%) anxiety (phobia) was low. Kruskal-Wallis test showed a significant relation between age and DA. The mean CDAS scores were high in 25-35 (11.08) and low in 55-65 (9.45) year age groups. Mann-Whitney U test showed significant relation between sex and DA. Mean CDAS score levels were significantly higher in females (10.88) than in males (9.96) (P < 0.0001).

Conclusion:

Patients anxious about dental procedures are often more difficult to treat. If Dentists become aware about the level of DA among their patients, they can anticipate patient's behavior and can be prepared to take behavioral/pharmacological measures to reduce anxiety levels.

Toward the validation of visual analogue scale for anxiety

Anxiety is a relevant problem in dental practice. The Visual Analogue Scale for Anxiety (VAS-A), introduced in dentistry in 1988, has not yet been validated in large series. The aim of this study is to check VAS-A effectiveness in more than 1000 patients submitted to implantology. The VAS-A and the Dental Anxiety Scale (DAS) were administered preoperatively to 1114 patients (459 males and 655 females, age 54.7 ± 13.1 years). Statistical analysis was conducted with Pearson correlation coefficient, the receiver operating characteristic (ROC) curve, and McNemar tests. A close correlation between DAS and VAS-A was found (r  =  0.57, P < .0001); the VAS-A thresholds of dental anxiety and phobia were 5.1 and 7.0 cm, respectively. Despite a significant concordance of tests in 800 cases (72%), disagreement was found in the remaining 314 cases (28%), and low DAS was associated with high VAS-A (230 cases) or vice versa (84 cases). Our study confirms that VAS-A is a simple, sensitive, fast, and reliable tool in dental anxiety assessment. The rate of disagreement between VAS-A and DAS is probably due to different test sensitivities to different components of dental anxiety. VAS-A can be used effectively in the assessment of dental patients, using the values of 5.1 cm and 7.0 cm as cutoff values for anxiety and phobia, respectively.

Dental anxiety in adults in Bulgaria

The anxiety experienced by some patients before or during dental visits poses a problem for patients and the dental practitioners alike. Some people consider them a stressful experience which manifests itself as anxiety, fear and even phobia and results in avoidance of proper dental care. The dental anxiety, dental fear and dental phobia stand out against the background of general anxiety. The aim of the present study was to investigate dental anxiety in Bulgaria by means of a self-assessment scale.

MATERIAL AND METHODS

The self-assessment Dental Anxiety Scale (DAS), developed by N Corah, was used in the form of a questionnaire containing questions about the gender, age, education and occupation of respondents. Subjects were 746 adults aged 18-82 years living in urban areas. Individual and group interviews were conducted directly with them.

RESULTS

The respondents with moderate dental anxiety were the most of all subjects (35.5%, DAS score: 9-12 points), followed by the anxiety-free subjects (34.6%, 4-8 points). The third most numerous group was the high anxiety group (18.2%, 13-14 points), followed by the subjects with severe anxiety (11.7%, 15-20 points). The mean score was 10.26 +/- 0.14. We found a statistically significant correlation between anxiety, age (P < 0.05), education (P < 0.05) and type of labour (manual or mental labour) (P < 0.01). No significant difference was found between anxiety and sex (P > 0.05).

CONCLUSIONS

The percentage of people scoring high on dental anxiety (DAS 13-20) in Bulgaria (29.9%) is considerably higher than that in some European and North American countries. The present study is the first in Bulgaria on dental anxiety. Further studies are needed to reveal other factors related to dental anxiety.

Dental caries risk indicators among Australian Aboriginal young adults

OBJECTIVES

To determine dental caries risk indicators among a birth cohort of Australian Aboriginal young adults (n=442).

METHODS

Data were from the Aboriginal Birth Cohort study, a prospective longitudinal investigation of Aboriginal individuals born 1987-1990 at an Australian regional hospital. Models representing demographic, socioeconomic, behavioural, dental service utilization and clinical oral health variables were tested using multivariate regression.

RESULTS

The percent DT>0 was 72.9 (95% CI 68.7-77.1), mean DT was 4.19 (95% CI 3.8-4.6), percent DMFT>0 was 77.4 (95% CI 73.5-81.3) and mean DMFT was 4.84 (95% CI 4.4-5.3). After controlling for other covariates, risk indicators for percent DT>0 included soft drink consumption every day or a few times a week (PR 1.25, 95% CI 1.08-1.45), not consuming milk every day or a few times a week (PR 1.16, 95% CI 1.04-1.30) and sweet consumption every day or a few times a week (PR 1.18, 95% CI 1.04-1.33). Risk indicators for mean DT included sweet consumption every day or a few times a week (B=1.14, 95% CI 0.27-2.02), nonownership of a toothbrush (B=0.91, 95% CI 0.10-1.87) and presence of plaque (B=2.46, 95% CI 0.96-3.96). Those with 4 +  occupants in their house the previous night had 1.2 times the prevalence of having DMFT>0 than their counterparts with less household occupants (95% CI 1.01-1.49). Percent DMFT>0 was also associated with consumption of soft drink every day or a few times a week (PR 1.18, 95% CI 1.04-1.34) and consumption of sweets every day or a few times a week (PR 1.23, 95% CI 1.10-1.37). Mean DMFT was higher among those who consumed sweets every day or a few times a week (B = 0.13, 95% CI 0.05-0.22) and who had dental anxiety (B=0.10, 95% CI 0.01-0.19).

CONCLUSIONS

In an Australian Aboriginal young adult cohort, risk indicators for dental caries included social determinants such as household size, dietary behaviours such as regular consumption of soft drink and sweets, dental behaviour such as nonownership of a toothbrush and dental anxiety.

Italian version of Corah's Dental Anxiety Scale: normative data in patients undergoing oral surgery and relationship with the ASA physical status classification

To test the Italian translation of Corah's Dental Anxiety Scale (DAS) and to check the relationship between dental anxiety and the American Society of Anesthesiologists (ASA) physical status classification (ASA-PS), the DAS was translated into Italian and administered to 1072 Italian patients (620 male and 452 female patients, ages 14-85 years) undergoing oral surgery. Patients' conditions were checked and rated according to the ASA-PS. The DAS ranged from 4 to 20 (modus=8, median=10); 59.5% of patients had a DAS of 7-12, 26.1% had a DAS>2, and 10.3% had a DAS>15. The mean DAS was 10.29 (95% confidence limit=0.19); female patients were more anxious than male patients (P< .001), while patients older than 60 years showed a significant decrease in the level of anxiety. Five hundred two patients were rated as ASA-PS class P1, 502 as ASA-PS class P2, and 68 as ASA-PS class P3, with a mean DAS score of 9.69, 10.78, and 11.09, respectively: the DAS difference between groups was significant (P< .001).

Needs in screening cardiovascular parameters during dental care in the elderly

AIMS

The aim of this study was to compare physiological reactivity during oral care between elderly and young subjects.

MATERIALS AND METHODS

Heart rate (HR), systolic and diastolic blood pressure (SBP and DBP) and blood oxygen saturation (SPO2) were recorded seven times during two consecutive dental impression sessions in 31 complete denture wearers (aged 60.7+/-11.44 yrs) and 31 young subjects (aged 21.8+/-1.5 yrs). Subjects also reported pain and anxiety on a visual analogue scale.

RESULTS

In the group of young subjects, SBP and DBP increased after the first impression and remained unchanged after the second. In the group of elderly persons, SBP and DBP increased significantly during both first and second dental impressions. Intergroup comparisons showed a longer-term relative increase in SBP and DBP in the group of elderly subjects.

CONCLUSIONS

These results emphasize the need to screen cardiovascular parameters during dental care in elderly subjects.

Dental fear and oral health habits among adults in Finland

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.

Association between dental fear and dental attendance among adults in Finland

OBJECTIVE

Our aim was to evaluate the association between dental attendance and dental fear while considering the simultaneous effects of perceived oral health and treatment need, satisfaction with oral health services, age, gender, marital status, and attained level of education.

MATERIAL AND METHODS

The two-stage stratified cluster sample (n=8028) represented Finnish adults aged 30 years and older. The response rate to this nationwide sample was 88%. Dental fear was measured with the question: "How afraid are you of visiting a dentist?" Multiple logistic regression analyses were used to determine the association between dental fear and dental attendance, including the following independent variables: perceived oral health, perceived treatment need, satisfaction with oral health services, age, gender, marital status, and attained level of education.

RESULTS

Among all ages, except 30 to 34-year-olds, irregular attenders were more likely to be very afraid of visiting a dentist than regular attenders were. The association was stronger the older the age group. Only age modified the association between dental fear and attendance. Irregular dental attendance can be attributed to high dental fear (etiologic fraction among exposed) in 41% of cases.

CONCLUSION

Reducing dental fear would increase the number of regular attenders, especially among older age groups. Individuals for whom oral health services have been provided regularly since childhood seem to continue to use these services regularly despite high dental fear.

Emergency Dental Clinic Patients in South Devon, their Anxiety Levels, Expressed Demand for Treatment under Sedation and Suitability for Management under Sedation

Objective

To assess the anxiety levels of patients attending two salaried dental service emergency clinics, their expressed demand for treatment under sedation, and their medical suitability for dental sedation.

Design

A questionnaire survey, incorporating the Modified Dental Anxiety Scale (MDAS) and assessment of American Society of Anesthesiologists’ (ASA) physical status classification, of all adult patients attending two emergency dental clinics in Torquay and Newton Abbot.

Results

513 patients returned questionnaires. Only five declined to take part in the study. The mean MDAS for patients attending the two emergency dental clinics was 14.09 (SD 6.04) and 41.9% of patients were classified as dentally anxious (MDAS >15). A preference for treatment under sedation was expressed by 56.3%, of all patients, of whom 50.5% were classified as ASA 1 (without health problems) and would have been suitable for sedation in primary dental care.

Conclusions

The reported dental anxiety levels of patients attending the two emergency dental clinics were found to be much higher than those found by previous studies in general dental practice and at dental school emergency clinics. There was a high expressed demand for treatment under sedation. Further studies are needed to assess the levels of dental anxiety seen at other dental emergency clinics and a health needs assessment to determine need as opposed to expressed demand.
