Assessing dental anxiety, dental care use and oral status in older adults

The Influence of Anxiety on Postoperative Quality of Life Regarding Implant Treatments: An Epidemiological Study

Dental treatment anxiety is highly prevalent worldwide. This is particularly important in the field of implantology since, in daily clinical practice, it translates into an increase in the difficulty of treatments, extending surgical times and having repercussions in the postoperative period. The aim of this multicentre, cross-sectional, epidemiological study was to determine the influence of anxiety levels in the postoperative period of an implant treatment on patients treated at two dental departments in Extremadura (Spain). To analyse anxiety levels, the modified Corah's Dental Anxiety Scale questionnaire was administered before surgical treatment. To analyse the postoperative period, another questionnaire was provided 7 days after surgery. The study was conducted on a total of 102 patients (55 men and 47 women), with a mean age of 47.99 years. The results indicated that patients with a high and severe degree of anxiety had a poorer quality of life in general. Patients with a higher degree of anxiety perceived greater swelling at 24, 48, 72 h and one week after surgery.

Perceived experiences of racism linked to dental fear and anxiety among Black women

OBJECTIVES

Dental fear and anxiety are known determinants of delaying or avoiding dental care and vary considerably based on factors such as age and gender. However, little is known about dental fear and anxiety in racial/ethnic minority populations, which bear a disproportionate burden of poor oral health outcomes. Structural and social pathways responsible for producing these disparities are also understudied. Experiences of racism over the lifecourse may contribute to poor oral health outcomes through a pathway of dental fear and anxiety. This paper aimed to evaluate perceived experiences with racism, dental fear and anxiety, and the utilization of dental services, in the Black Women's Health Study (BWHS), a United States-based prospective cohort.

METHODS

Analysis of prospective data obtained from a geographic subset of participants in the BWHS was conducted. In 2014, BWHS participants residing in Massachusetts responded to a mailed oral health questionnaire that included the Index of Dental Anxiety and Fear (IDAF-4C+) instrument (N = 484; 69% response rate). Previously collected demographic and health information, along with reported experiences of everyday and lifetime racism, obtained from national BWHS questionnaires between 1995 and 2009, were merged with the Massachusetts-based sub-sample. Associations between high dental anxiety (HDA) (mean IDAF-4C+ score ≥2.5 on the dental fear and anxiety module) and oral health outcomes and perceived racism and HDA were explored via prevalence ratios (PR) calculated using log-binomial regression models, including adjustment for potential confounders.

RESULTS

Reported exposures to everyday racism occurred weekly on average for the top 25% of the sample, while 13% of participants reported exposure to multiple (n = 3) experiences of unfair treatment due to their race over their lifetime. HDA was prevalent among 17.8% of the sample and was significantly associated with indicators of poor oral health status. High exposures to everyday and lifetime experiences of racism were positively associated with HDA (PR = 1.08; 95% CI: 0.90, 1.58 and PR = 1.72; 95% CI: 1.03, 2.88, respectively).

CONCLUSIONS

Significant associations between racism and HDA, and between HDA and poor oral health and reduced utilization of dental care were observed. Dental anxiety may be a pathway through which perceived experiences with racism may impact oral health outcomes.

Factors Influencing Parents' Decision in Choosing a Pediatric Dentist

Introduction Pediatric dentists support children's dental health while also providing parents with health education and information. Parents are guardians of their children's oral health, as their knowledge, beliefs, also attitude about oral health can influence early childhood oral health directly or indirectly. Recognizing parenting practices on early childhood oral health is essential for developing effective prevention and treatment strategies for the child, because parents' health attitudes, behavior, and their children's dental health are usually influenced directly or indirectly by their practice. Objectives of this study were to find out what factors parents prefer while choosing a pediatric dentist for their kids, to assess parent attitudes towards management of a symptomatic primary tooth, to analyze parental understanding of the importance of deciduous teeth, and to assess parent knowledge and perception regarding their child. Methodology A cross-sectional study conducted at Sharad Pawar Dental College and Hospital was done, where 20 questions were posed to the parents who came with their children for dental treatment. Questions were divided into two parts, knowledge-based assessment scale and perception-based assessment scale. The questions were formulated to assess the knowledge of parents regarding dental care, their perception, and their attitude toward the decision-making while selecting a pediatric dentist for their kids. The questions also included information about the child's habits and associated problems with it. Three hundred parents of children under 14 years of age were chosen randomly where all parents were adequately informed beforehand, and their written consent was taken before proceeding with the questions. All the questions were formulated in the native language that they could easily understand. A convenient method was applied as per the respondent from an offline questionnaire survey.  Results By evaluating the parental knowledge as well as perception towards children's oral health and dental treatment we are able to determine which aspects parents prefer while selecting a pediatric dentist for their child. The study found that parents had limited knowledge about the causes, treatment, prevention, and consequences of oral health problems in children. Many parents neglect oral health problems and lack correct knowledge. Conclusion  Hence this study assesses the parental knowledge as well as perception towards children's oral health. This study concludes that it is crucial to raise awareness about oral health among parents and inform them about available treatments, consequences of negligence and future problems to aid them in decision-making.

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.

Is There Any Association Between Chronic Periodontitis and Anxiety in Adults? A Systematic Review

Periodontitis is a multifactorial disease triggered by dysbiotic biofilms, involving the host's immune response, systemic and behavioral factors, including psychosocial conditions. This systematic review aimed to investigate the possible association between periodontitis and anxiety in adults. Searches were performed in PubMed, Scopus, Web of Science, Lilacs, Cochrane, and OpenGrey databases, without language restrictions, considering studies in adults (P-Participants), with (E-Exposure) and without periodontitis (C- Comparison) in an outcome of association with anxiety (O-outcome). Methodological quality assessment was carried out using the Newcastle-Ottawa protocol for case-control and cross-sectional studies, followed by an analysis of the level of evidence using the GRADE tool. Metanalysis was not performed due to several differences in methods applied by authors in primary studies. Eleven observational studies were selected according to the inclusion criteria from the total of 6,380 studies retrieved from databases. Eight studies demonstrated higher anxiety levels in subjects with periodontitis, among which only one study presented a high risk of bias. The GRADE tool revealed a low level of evidence for the anxiety outcome measured by the State-Trait Anxiety Inventory (STAI), both for case-control and cross-sectional studies. However, since anxiety may affect the quality of life of many subjects, it reinforces the need for further studies that evaluate this association for more extended periods.

Evaluation of Anxiety, Pain, and Hemodynamic Changes during Surgical Removal of Lower Third Molar under Local Anesthesia

Aim:

The aim of this study are to determine the hemodynamic changes in healthy patients during the surgical removal of lower third molar and to evaluate whether these variations are attributable to patient anxiety and pain experienced during surgical procedure.

Materials and Methods:

Sixty healthy patients were evaluated (i) to determine the hemodynamic changes (systolic blood pressure [SBP], diastolic blood pressure [DBP], heart rate [HR], and oxygen saturation) at nine occasions: before starting the surgical procedure, 1 min and 4 min after local anesthetic injection, during the incision, at the time of ostectomy, at the completion of tooth removal, at the start and completion of suturing, and finally, after completion of surgery and (ii) to evaluate whether these variations are attributable to patient anxiety and pain experienced during the surgical procedure. Hemodynamic variables were compared between the gender and at different time points by performing two-way analysis of variance for repeated measures. Global mean values of hemodynamic variables were compared between male and female using unpaired t-test. Categorical variables were compared by Chi-square test. All the tests were two-sided. P < 0.05 was considered statistically significant.

Results:

SBP and DBP showed significant changes; the highest value was recorded at the time of ostectomy/tooth sectioning. Maximum HR was observed 4 min after local anesthetic injection and the lowest HR was recorded after completion of tooth extraction, i.e., during the suturing. In females, mean HR was significantly increased.

Conclusion:

The present study suggests that dental anxiety impacts the effect of delivery of local anesthesia on blood pressure and is significantly associated with increased HR.

Validity and reliability of an Arabic version of the state-trait anxiety inventory in a Saudi dental setting

Objectives:

To test the psychometric properties of an adapted Arabic version of the state trait anxiety-form Y (STAI-Y) in Saudi adult dental patients.

Methods:

In this cross-sectional study, the published Arabic version of the STAI-Y was evaluated by 2 experienced bilingual professionals for its compatibility with Saudi culture and revised prior to testing. Three hundred and eighty-seven patients attending dental clinics for treatment at the Faculty of Dentistry Hospital, King Abdullah University, Jeddah, Kingdom of Saudi Arabia, participated in the study. The Arabic version of the modified dental anxiety scale (MDAS) and visual analogue scale (VAS) ratings of anxiety were used to assess the concurrent criterion validity.

Results:

The Arabic version of the STAI-Y had high internal consistency reliability (Cronbach’s alpha: 0.989) for state and trait subscales. Factor analysis indicated unidimensionality of the scale. Correlations between STAI-Y scores and both MDAS and VAS scores indicated strong concurrent criterion validity. Discriminant validity was supported by the findings that higher anxiety levels were present among females as opposed to males, younger individuals as compared to older individuals, and patients who do not visit the dentist unless they have a need as opposed to more frequent visitors to the dental office.

Conclusion:

The Arabic version of the STAI-Y has an adequate internal consistency reliability, generally similar to that reported in the international literature, suggesting it is appropriate for assessing dental anxiety in Arabic speaking populations.

Assessment of anxiety in patients who undergo surgical procedures for tooth implants: a prospective study

PURPOSE

The purpose of this study is to evaluate general anxiety using the State-Trait Anxiety Inventory (STAI) and dental anxiety using the Corah Dental Anxiety Scale (Corah-DAS) in patients who underwent surgical procedures for dental implants.

METHODS

The study was performed with 55 patients who underwent implant surgery, of whom 37 were treated at a university and 18 were treated at a private office. General anxiety (STAI) and dental anxiety (Corah-DAS) were assessed at three different time points: appointment prior to clinical procedures (T1), day of procedures (just before the procedures; T2), and first post-procedure appointment (T3). The data were analyzed using analysis of variance followed by the Duncan test or Student's t-test.

RESULTS

State anxiety increased on the day of surgery (T2), whereas trait anxiety was higher at T1 (both p < 0.05). Women (n = 41) presented higher state anxiety at T2 than men (n = 14). Patients who were treated at the university (n = 37) exhibited higher state anxiety at both T1 and T3 than patients who were treated in a private practice (n = 18). Individuals with lower dental anxiety at T1 were those who reported having good experiences with dental treatment.

CONCLUSIONS

An increase in state anxiety was observed immediately before surgical procedures, and this increase was more pronounced in females. Although the Corah-DAS has been used as an indicator of dental anxiety, the STAI appears to be more sensitive for the measurement of anxiety. The application of appropriate methods is essential for ascertaining anxiety in patients, which should be considered in oral surgeries.

Does watching a video on third molar surgery increase patients' anxiety level?

OBJECTIVE

To identify the effects of watching live taping of third molar removal on patients' anxiety levels before and after extraction.

STUDY DESIGN

This study was based on a prospective, cross-sectional, observational investigation of the different patient education techniques about the effect of third molar removal on patients' anxiety level. A total of 333 patients were randomized into three groups: two study groups (for group 1, basic information was given verbally; for group 2, which was the study group, basic information was given verbally and through a movie on third molar extraction); and a control group (basic information was given verbally; it did not include information on operative procedures and recovery). Anxiety levels were assessed by using the Dental Anxiety Scale (DAS) and the Spielberger State-Trait Anxiety Inventory (STAI). Pain was assessed with a visual analog scale. Statistical analysis was performed with SPSS 16.0.

RESULTS

Group 2 patients were significantly more anxious before the surgical procedure, and the most significant decreases in DAS and STAI scores were observed in that group. The age, surgery time, and education level were not correlated with anxiety or pain levels; however, female patients had high levels of anxiety (P < .05).

CONCLUSION

Preoperative multimedia information increases the anxiety of patients undergoing third molar surgery.

Estimating the need for dental sedation. 3. Analysis of factors contributing to non-attendance for dental treatment in the general population, across 12 English primary care trusts

BACKGROUND

This is the third paper in a series of four examining a tool which could be used to determine sedation need among patients.

AIM

The aim of this paper was to assess the reasons why people do not attend the dentist regularly, in order to understand the potential need for sedation services among both attending and non-attending patients.

METHODS AND RESULTS

A large telephone survey conducted across 12 primary care trusts (PCTs) found that 17% of participants did not attend the dentist regularly. One of the top reasons given for non-attendance that could be considered a barrier was fear/anxiety. The figure reached in paper 2 ( 2011; 211: E11) stated that approximately 5% of attending patients will, at some time, need sedation services. However, the data from this survey have suggested that anxiety accounts for 16% of people who do not attend the dentist regularly.

CONCLUSION

It could be assumed that if non-attending patients were included, with high levels of anxiety, the sedation need would rise to 6.9% throughout the entire population.

The relationship between dental anxiety and dental decay experience in antenatal mothers

The aim of this study was to investigate the relationship between dental anxiety and dental decay experience among antenatal mothers attending Maternal and Child Health clinics in Malaysia. A cross-sectional study was conducted on a consecutive sample of 407 antenatal mothers in Seremban, Malaysia. The questionnaire consisted of participants' demographic profile and the Dental Fear Survey. The D(3cv)MFS was employed as the outcome measure and was assessed by a single examiner (intraclass correlation = 0.98). A structural equation model was designed to inspect the relationship between dental anxiety and dental decay experience. The mean Dental Fear Survey score for all participants was 35.1 [95% confidence interval (34.0, 36.3)]. The mean D(3cv)MFS score was 10.8 [95% confidence interval (9.5, 12.1)]. Participants from low socio-economic status groups had significantly higher D(3cv)MFS counts than those from high socio-economic status groups. The path model with dental anxiety and socio-economic status as predictors of D(3cv)MFS showed satisfactory fit. The correlation between dental anxiety and dental decay experience was 0.30 (standardized estimate), indicating a positive association. Socio-economic status was also statistically significantly associated with the D(3cv)MFS count (beta = 0.19). This study presented robust evidence for the significant relationship between dental anxiety and dental decay experience in antenatal mothers.

Independent predictors of satisfaction in impacted third molar surgery patients

OBJECTIVES

Patient satisfaction and dissatisfaction are critical dimensions leading to favorable or unfavorable treatment outcomes. Although impacted third molar (ITM) surgery is one of the most common dental surgical procedures, it is a challenging operation because of numerous potential complications and patients generally suffer from severe psychosomatic symptoms as a result of severe perioperative anxiety. We hypothesize that multiple independent factors, including perioperative anxiety and various postoperative complications, affect satisfaction of the ITM surgery patients.

METHODS

Survey data from 219 participants encompassed basic patient demographic traits, difficulty of surgery, perioperative anxiety, pain sensation and common postoperative complications. The t-test and one-way anova with Duncan's multiple-range tests were applied to detect differences in mean values of perioperative anxiety, perioperative pain sensation and satisfaction based on basic demographic characteristics and postoperative complications. The significance of postoperative complications according to demographic data and difficulty of extraction was also analyzed. A paired t-test was applied to detect the significance of anxiety level and pain sensation changes over time. Lastly, univariate and multiple stepwise regression analyses were used to analyze the relationships among perioperative anxiety, pain sensation and satisfaction to determine the predictive factor of patient satisfaction.

RESULTS

Basic demographic traits proved not to have a direct significant effect on satisfaction in ITM surgery patients, but some demographic factors and difficulty of surgery showed significant relationships with postoperative complications. Univariate analysis revealed that perioperative anxiety, pain sensation, postoperative infection, numbness/paresthesia and ecchymoses have a significant influence on patient satisfaction. In particular, preoperative anxiety level and numbness/paresthesia were independent predictive factors of patient satisfaction upon multivariate analysis.

CONCLUSIONS

This study demonstrates that the patients who undergo ITM surgery often have severe anxiety that seriously impacts patient satisfaction and resultant treatment outcomes. In addition, patient satisfaction directly depends on the occurrence of some postoperative complications. Appreciation of these predictive factors and increasing patient satisfaction may help clinicians to provide optimal care for ITM surgery patients.

Portuguese version of Corah's Dental Anxiety Scale: transcultural adaptation and reliability analysis

This study explores the psychometric properties of the Portuguese version of Corah's Dental Anxiety Scale (DAS), an instrument designed to assess the manifestations of dental anxiety. The DAS has been translated into several languages, but no adaptation and reliability analysis of the Portuguese version of the scale has yet been carried out. A total of 747 Brazilian undergraduate students participated in this study. The instrument proved to have good internal consistency and test-retest reliability. Furthermore, we observed that women are more anxious during dental treatment routines compared to men. Our findings suggest that the Portuguese version of DAS is a reliable instrument for assessing adults' dental anxiety traits, and can be used for both clinical and research purposes.

Prevention and early detection of oral and pharyngeal cancer in veterans

OBJECTIVES

To assess knowledge of oral and pharyngeal cancer (OPC) clinical signs and risk factors, the association between the risk factors and OPC, and the experience with OPC screening between newly diagnosed OPC patients and controls among a population of veterans in North Carolina.

STUDY DESIGN

A case-control study with 31 OPC cases and 30 frequency-matched controls recruited from 2003 to 2004. Bivariate analysis using chi-square statistics and multivariate logistic regression was implemented to estimate the association with OPC.

RESULTS

Only 34% of respondents knew 1 clinical sign and 4 or 5 risk factors for OPC. The lifetime accumulation of tobacco had a significant relationship with OPC (>20 pack-years; OR, 3.2; 95% CI, 1.01-10.3). Many respondents had not had an oral cancer examination within 3 years, mostly through ignorance. Most VA OPC patients were diagnosed by physicians, rather than by dentists.

CONCLUSIONS

A considerable knowledge deficit on OPC was found among North Carolina veterans. Use of tobacco was a risk factor for OPC in this population.

Problemas comportamentais e stress em crianças com ansiedade frente ao tratamento odontológico

A situação de tratamento odontológico em geral está relacionada à ansiedade e ao stress; a dor e os aspectos fisiológicos e psicológicos envolvidos no tratamento podem ser avaliados pelos pacientes, em especial pelas crianças, como potencialmente ameaçadores ao seu bem-estar. Objetivou-se comparar, quanto ao estresse infantil e ao perfil comportamental, um grupo de crianças que apresentam um alto nível de ansiedade frente ao tratamento odontológico (G1) a um grupo de crianças que colaboram com o atendimento (G2). Procedeu-se a aplicação dos instrumentos: Escala Comportamental A2 de Rutter e Escala de Estresse Infantil. As crianças do G1 apresentaram mais indicadores de estresse e de dificuldades emocionais e comportamentais que as do G2 ( p < 0,01). Conclui-se que a utilização sistemática desses instrumentos no contexto de uma clínica-escola pode permitir a identificação de crianças com dificuldades e a aplicação de medidas profiláticas e de intervenção que minimizem a ocorrência de situações de dificuldades para a realização de tratamento odontopediátrico.

Anxiety measurements in university students undergoing third molar extraction

OBJECTIVE

This investigation was conducted to quantitate the anxiety associated with third molar extraction in university students, and to compare the measured anxiety before and after extraction and between men and women, first and second extraction, and impacted versus nonimpacted tooth extraction.

STUDY DESIGN

The Japanese version of The State-Trait Anxiety Inventory (STAI), a psychological test, was given to 108 students undergoing third molar extraction. The students completed the test on the first examination (day 1), immediately before the extraction (day 2), and the day after the extraction (day 3).

RESULTS

The state anxiety (STAI-S) score showed no significant difference between days 1 and 2, but the score on day 3 was lower than that on day 1, with a decrease in cases with a stage IV or V. Women showed more anxiety state on day 2 than men. The anxiety score on days 2 and 3 for the second extraction were significantly lower than those for the first extraction in 43 students who underwent third molar extractions twice. The change in the trait anxiety (STAI-T) stage was unremarkable among days 1, 2, and 3. No statistical difference was found in the anxiety between students undergoing impacted and nonimpacted third molar extraction.

CONCLUSIONS

The anxiety status of students undergoing third molar extraction could be quantitatively evaluated using the STAI. The results of this investigation may provide oral maxillofacial surgeons with useful information about patients' anxiety throughout the tooth removal process.

Seniors' attitudes: oral health and quality of life

The objective of this study was to determine what impact, if any, oral health was having on the quality of life for selected seniors in Prince Edward Island, Canada. The attitudes of seniors towards oral health and its relationship to quality of life is important to define. This self-reported assessment provides information on this particular relationship. The research design was a random cluster sampling that covered all geographical areas of Prince Edward Island. It represented the cultural diversity within these geographical areas. The survey instrument selected was the Subjective Oral Health Indicators' Status, a validated survey instrument. This particular instrument addressed all the issues raised in the objectives. Data were analysed using Pearson's correlation with age and number of teeth present. The independent t-test was used to identify differences in responses by gender. Results of the survey showed identification of individual indicators that were having an impact on quality of life. Gender differences in responses were identified in four of the eight subject areas. The level of worry/concern was inconclusive because of the high non-response rate to the last question. Non-response rates increased with each topic in the questionnaire. More research is needed to identify clinical needs of seniors on Prince Edward Island. Qualitative study to determine attitudes and beliefs could provide groundwork for future programme design.

Effect of medical, drug abuse, and mental health care on receipt of dental care by drug users

We examined the association of patterns of health care in 1996 with subsequent dental care in 1997 or 1998 for 47,260 drug users enrolled in New York State Medicaid. From Medicaid files, we identified psychiatric care, prescribed antidepressants, a regular source of medical care, regular drug treatment (6+ contiguous months), and clinical conditions. Of this cohort, 58% received dental care. The adjusted odds ratios (AOR) of dental care were increased for drug users receiving psychiatric care and antidepressants (1.66 [1.55, 1.77]), psychiatric care alone (1.48 [1.41, 1.56]), or only antidepressants (1.18 [1.10, 1.27]), vs. neither. AORs of dental care were also higher for those with a regular source of medical care alone (1.27 [1.23, 1.35]) or with regular drug treatment (1.33 [CI 1.25, 1.41]) vs. neither. Mental health care and, to a lesser extent, a regular source of medical care and regular drug treatment may promote dental care in this vulnerable population.

Measurement and predictors of young adults' perceived ability to cope with dental life events

The purpose of the present study was to assess coping skills and predictors of the ability to cope with dental life events employing a 10-item rather than a 48-item rating questionnaire. A representative random sample of 1490 subjects aged 25 years from 3 Norwegian counties received a mail questionnaire in March 1997. The response rate was 62% after 1 reminder. Eight selected items from the Social Readjustment Rating Questionnaire (SRRQ) plus 2 dental items were presented as graphic rating scales with the endpoints 'not difficult at all' and 'more difficult than anything'. Mean values were used to rank the life events and for comparison with findings from a previous study. Information was also collected for 16 predictor variables (Table 2). The informants found it moderately difficult to cope with losing one or more teeth and with getting dentures. A 10- and a 48-item rating scale seemed to give comparable results. In multiple logistic regression analysis, controlling for having experienced extraction during the previous 5 years, gender, and dental anxiety were significant predictors of both dental life events; education, many cavities, and belief in keeping teeth for life influenced coping with getting dentures. The identified predictors of dental life events explained <11% of the variance. In addition to extending the list of predictors of perceived need for skills to adjust to dental life events, the study also provided evidence to suggest that it may be acceptable to rely on a shorter rating questionnaire.

The sound of the dentist's drill and students' anxiety scores

In a sample of 42 college students, a positive correlation of .51 with sound and .56 without sound was found between EMG scores and their total Dental Anxiety Scale scores for those who did and did not hear the drill.

Factors associated with dental anxiety among older people in Britain

OBJECTIVE

This paper reports on a study of dental anxiety among adults aged 60 years living independently in Britain.

DESIGN

A national cross-sectional study carried out with the assistance of the Office for National Statistics' Omnibus Surveys in 1999.

SETTING

Data was collected by face to face interviews with older people in their homes.

MEASUREMENTS

Data on dental anxiety were collected from 973 subjects by means of face to face interviews and was measured by the Dental Anxiety Scale (DAS) (Corah, 1969). In addition, data on dental service use and oral health status (self-reported) was collected.

RESULTS

The mean DAS score was 8.4 (sd 3.5), and 13% (129) of subjects were classified as dentally anxious (DAS > or = 13). DAS scores were associated with numerous socio-demographic factors (P < 0.01), self-reported oral health status (P < 0.01) and dental service (P < 0.01) factors. A series of regression analyses revealed that dental anxiety was a significant predictor of a number of behavioural and oral health outcomes.

CONCLUSION

One in eight older people in Britain are dentally anxious and this is associated with their use of services and oral health status (self-reported).

Non-institutionalized elderly dental patients in Israel: socio-demographics, health concerns, and dental anxiety

The purpose of this study was to evaluate which factors might influence health care attitudes such as anxiety about dental care by older adults in Israel. The study population consisted of 103 non-institutionalized patients (46 men and 57 women) over the age of 65 who attended a dental clinic that provided services for older adults during a one-year period. Socio-demographic information and information about the subjects' general health and their level of concern about health problems were obtained from self-reported questionnaires, while the dental anxiety level was found by means of a dental anxiety scale (DAS). Ninety-nine percent of the patients suffered from a major systemic disease such as diabetes, hypertension, atherosclerosis, respiratory disease, and rheumatic disease. Both unmarried and first-time patients expressed high anxiety scores. Patients with 12 or fewer years of formal schooling demonstrated significantly higher dental anxiety. Among patients who regularly attended a synagogue or a social club, concern about oral health was significantly higher than for the rest (p < 0.02). No association was found between having dentures and gender, or between having dentures and level of education. The reason for visiting the clinic (inability to eat, pain, or esthetics) was not associated with any other health concern or with dental anxiety levels. This study determined that patients who were unmarried, less educated, or attending the facility for the first time were more likely to experience dental anxiety. These patients merit special consideration.

Dental care access and use among HIV-infected women

OBJECTIVES

This study sought to identify predictors of dental care use in HIV-infected women.

METHODS

In a cross-sectional survey of HIV-infected women enrolled in the northern California site of the Women's Interagency HIV Study, dental care use and unmet need were assessed in relation to selected variables.

RESULTS

Among 213 respondents, who were predominantly Black and younger than 45 years, 43% had not seen a dentist and 53% (among dentate women) reported no dental cleaning in more than a year (although 67% had dental insurance coverage, mainly state Medicaid). Nine percent were edentulous. Among nonusers of dental care, 78% reported that they wanted care but failed to get it. Barriers included fear of and discomfort with dentists, not getting around to making an appointment, and not knowing which dentist to visit. Multivariate analysis showed that lack of past-year dental care was associated mainly with unemployment, a perception of poor oral health, and edentulism.

CONCLUSIONS

HIV-positive women appear to be underusing dental care services. Fear and lack of information regarding available resources, in addition to unemployment and perception of poor oral health, may be important barriers.

Dental fear and anxiety as a barrier to accessing oral health care among patients with special health care needs

Persons with special health care needs due to physical and cognitive impairment can be at increased risk for dental disease which can be attributed to, as well as exacerbate, existing medical conditions. This study assessed the nature of perceived barriers to obtaining oral health care among a special-needs population and the influence of these factors (in particular, fear and anxiety) on utilization of dental services. A total of 27.9% of the sample reported fear/anxiety about dental visits, with approximately half of those reporting to be very nervous or "terrified". There was an inverse relationship between the frequency of dental visits and the proportion of respondents reporting themselves as very nervous or terrified, and between the perception of oral health status and the level of dental fear/anxiety (P < 0.001). A large difference was reported between patient preference for pharmacologic modalities for anxiety control and those received at dental visits, with 40% of the youngest age group indicating that they would go to the dentist more frequently if sedation or general anesthesia were offered. The levels of self-reported fear/anxiety and the high proportion of respondents indicating an unmet need for adjunctive anesthesia services suggest that fear/anxiety acts as a barrier to dental care among this special-needs group which could be ameliorated with greater use of these services.
