A radiographic study of dental health in adult patients with dental anxiety

The role of neuroticism and pain in dental anxiety: A twin study

OBJECTIVES

Accumulating evidence has revealed that dental anxiety is robustly associated with dental care-related pain and discomfort, but also with the personality trait of neuroticism (i.e. the relatively stable disposition to experience the world as distressing, threatening and unsafe). However, there is a near absence of research on these risk factors in samples for which genetic information is available. With the aim of arriving at a more refined understanding of dental anxiety, this twin cohort study assessed genetic and environmental influences on neuroticism, dental care-related pain and dental anxiety, and the relation between these phenotypes.

METHODS

Participants were recruited from the Norwegian Twin Registry, and data collections were carried out in 1992-98 (Time 1) and 2011 (Time 2). Well-validated questionnaires were used to assess the study variables, including Corah's Dental Anxiety Scale, the Numerical Pain Rating Scale, the NEO Personality Inventory Revised (Time 2) and Eysenck's Personality Questionnaire (Time 1). Pearson correlation analysis and generalized estimating equations (GEE) were used to investigate phenotypic associations. Analyses of genetic and environmental influences were performed using Cholesky modelling.

RESULTS

A total of 746 monozygotic (MZ) and 770 dizygotic (DZ) twins in the age group of 50-65 participated in the study. Moderate estimates of heritability for dental anxiety (0.29), treatment-related pain (0.24) and neuroticism (0.45-0.54) were found. Cholesky modelling showed furthermore that neuroticism assessed at Time 1 and Time 2 was related to dental anxiety and pain via both genetic and individual-specific environmental pathways, albeit not very strongly. The particularly high phenotypic correlation observed between dental care-related pain and anxiety (r = .68) was explained by both overlapping genetic and individual-specific environmental influences (the genetic and environmental correlations were .84 and .63 respectively).

CONCLUSIONS

The findings provide deeper insight into the aetiology of dental anxiety and confirm that while it is strongly linked to treatment-related pain experiences, this relation is to a considerable degree independent of general negative affectivity/neuroticism.

The complexity of dental anxiety and its association with oral health-related quality of life: An exploratory study

This study aimed to explore the factors associated with oral health-related quality of life (OHRQoL) in a sample with high dental anxiety. Data were obtained from 107 patients attending a therapeutic treatment program for people who have experienced abuse and for those with dental phobia in Norway. Patients completed questionnaires, including the Index of Dental Anxiety and Fear, the Anxiety subscale of the Hospital Anxiety and Depression Scale, and the Oral Impacts on Daily Performance scale, measuring OHRQoL prior to treatment. The various measurement instruments were evaluated psychometrically, and the variables associated with OHRQoL were explored using hierarchical multiple regression. Symptoms of dental anxiety and general anxiety were high, while OHRQoL was poor. Dental anxiety, higher age, higher number of years since the last dental treatment, and higher general anxiety were discernibly associated with lower OHRQoL. The strongest association was found between general anxiety and OHRQoL. In conclusion, several factors were associated with OHRQoL in a sample with high dental anxiety, suggesting a complex picture of dental anxiety. When treating patients with high dental anxiety, dental practitioners should be aware that there may be factors complicating the therapeutic setting, such as general anxiety.

Relationship between Children's and Parents' Dental Anxiety: A Cross-Sectional Study on the Six European Countries

Background: The purpose of this study is to investigate the relationship between children’s and parents’ dental anxiety. Methods: 731 children of different ages and their parents from six European countries participated in this study. Dental anxiety was investigated through an online questionnaire, which consisted of general questions and the Corah Dental Anxiety Scale (CDAS), which is a questionnaire that measures respondents’ reactions on a 5-point scale for four different situations. Results: CDAS results were calculated for all children and their parents. A total of 12.5% of children from Croatia, 26.67% from Macedonia, 10.94% from Bosnia and Herzegovina, 20.31% from Montenegro, 23.08% from Slovenia and 16.10% from Serbia showed a high level of anxiety. The correlation between dental anxiety of parents and children was 0.4 (p < 0.01). Conclusions: Parents with negative experience from a dental office can have a bad effect on their child’s behaviour, which results in the creation of a non-active patient. Due to the clear and existing cause-and-effect relationship of dental anxiety in children and parents, it is extremely important to educate parents about the proper psychological approach to children in order to promote positive experiences from dental offices, as well as to emphasize the importance of regular visits to the dentist.

Held still or pressured to receive dental treatment: self-reported histories of children and adolescents treated by non-specialist dentists in Hordaland, Norway

Aim

This study aimed to estimate the prevalence of a self-reported history of restraint in children and adolescents when receiving dental care by non-specialist dentists and to assess differences in dental fear and anxiety (DFA), intra-oral injection fear, and trust in dentists between patients with and without a self-reported history of restraint.

Methods

An electronic cross-sectional survey was distributed to all 9 years old (n = 6686) and 17 years old (n = 6327) in the Public Dental Service in Hordaland County, Norway, in 2019. For statistical evaluation, we generated descriptive statistics and Mann–Whitney U tests.

Results

The response rate ranged between 43.5 and 59.9% for the different questions. The prevalence of a self-reported history of being held still against one’s will during dental treatment and pressured to undergo dental treatment against one’s will was 3.6% and 5.1%, respectively. In general, these patients reported higher DFA, and higher intra-oral injection fear compared with those without such histories of restraint. Patients who had reported being held still against their will during dental treatment had significantly higher distrust in dentists than those who did not report restraint (p < 0.001).

Conclusion

To feel pressured to receive dental treatment and to be held still against one’s will overlap with the concepts of psychological and physical restraint. Patients with a self-reported history of restraint recorded significant differences in DFA, intra-oral injection fear, and trust in dentists compared to those who did not report restraint. Future studies should explore the role that restraint may play in relation to a patient’s DFA, intra-oral injection fear, and trust in dentists.

Treatment of Dental Anxiety and Phobia-Diagnostic Criteria and Conceptual Model of Behavioural Treatment

Dental anxiety and dental phobia are still prevalent among adult individuals and should be considered a dental public health issue. Dental anxiety/phobia is often described as a vicious cycle where avoidance of dental care, poor oral health, and psychosocial effects are common features, often escalating over time. Treatment should include therapy for dental anxiety/phobia and oral diseases. This paper discusses aetiology, prevalence, and diagnosis of dental anxiety/phobia and, in detail, presents a conceptual treatment model at the Dental Fears Research and Treatment Center in Gothenburg, Sweden. In addition, based on systematic reviews, evidence-based treatment for dental anxiety is revealed including the interdisciplinary approach between psychology and dentistry.

The Current and Potential Application of Medicinal Cannabis Products in Dentistry

Oral and dental diseases are a major global burden, the most common non-communicable diseases (NCDs), and may even affect an individual's general quality of life and health. The most prevalent dental and oral health conditions are tooth decay (otherwise referred to as dental caries/cavities), oral cancers, gingivitis, periodontitis, periodontal (gum) disease, Noma, oro-dental trauma, oral manifestations of HIV, sensitive teeth, cracked teeth, broken teeth, and congenital anomalies such as cleft lip and palate. Herbs have been utilized for hundreds of years in traditional Chinese, African and Indian medicine and even in some Western countries, for the treatment of oral and dental conditions including but not limited to dental caries, gingivitis and toothaches, dental pulpitis, halitosis (bad breath), mucositis, sore throat, oral wound infections, and periodontal abscesses. Herbs have also been used as plaque removers (chew sticks), antimicrobials, analgesics, anti-inflammatory agents, and antiseptics. Cannabis sativa L. in particular has been utilized in traditional Asian medicine for tooth-pain management, prevention of dental caries and reduction in gum inflammation. The distribution of cannabinoid (CB) receptors in the mouth suggest that the endocannabinoid system may be a target for the treatment of oral and dental diseases. Most recently, interest has been geared toward the use of Cannabidiol (CBD), one of several secondary metabolites produced by C. sativa L. CBD is a known anti-inflammatory, analgesic, anxiolytic, anti-microbial and anti-cancer agent, and as a result, may have therapeutic potential against conditions such burning mouth syndrome, dental anxiety, gingivitis, and possible oral cancer. Other major secondary metabolites of C. sativa L. such as terpenes and flavonoids also share anti-inflammatory, analgesic, anxiolytic and anti-microbial properties and may also have dental and oral applications. This review will investigate the potential of secondary metabolites of C. sativa L. in the treatment of dental and oral diseases.

Dental care - an emotional and physical challenge for the sexually abused

The aim was to explicate persistent psychological and bodily memories of sexual abuse and how they are expressed during dental appointments. The participants comprised 13 sexually abused individuals (11 women), who recalled and expressed these experiences during a dental appointment. They were encouraged to describe, in detail, aspects of the appointment which triggered memories of the sexual abuse. The interviews were recorded, transcribed verbatim, and analyzed using Qualitative Content Analysis. The identified overall theme illustrating the latent content was 'An echo of sexual abuse transformed into (dys) functional reactions'. The first category covering the manifest content was 'The inner invisible struggle', with two subcategories: (i) mental inscriptions of the abuse experience; and (ii) consequences of the dental encounter. The second category was 'The discoverable manifestations', with two subcategories: (i) enigmatic communication; and (ii) expressions of bodily memories. The dental appointment arouses similar psychological stressful reactions as the episodes of abuse; both implicit and explicit expressions are recognizable. Dental staff can contribute to disclosure by improved understanding of the strain a dental appointment can cause in patients who have been subjected to sexual abuse and familiarity with the associated bodily expressions.

Associations between a history of sexual abuse and dental anxiety, caries experience and oral hygiene status among adolescents in sub-urban South West Nigeria

INTRODUCTION

Sexual and oral health are important areas of focus for adolescent wellbeing. We assessed for the prevalence of sexual abuse among adolescents, oral health factors associated with this history, and investigated whether sexual abuse was a risk indicator for dental anxiety, caries experience and poor oral hygiene.

METHODS

This was a cross-sectional study conducted between December 2018 and January 2019 among adolescents 10-19 years old in Ile-Ife, Nigeria. Survey data collected included respondents' age, sex, and socioeconomic status, oral health risk factors (dental anxiety, frequency of tooth brushing intake of refined carbohydrates in-between-meals, flossing, dental visits, smoking, alcohol intake, use of psychoactive substances), caries experience, oral hygiene status, history of sexual abuse, and sexual risk behaviors (age of sexual debut, history of transactional sex, last sexual act with or without condom, multiple sex partners). Regression models were constructed to determine the association between outcome variables (dental anxiety, presence of caries experience and poor oral hygiene) and explanatory variables (oral health risk factors and history of sexual abuse).

RESULTS

The prevalence of sexual abuse in our cohort was 5.9%: 4.3% among males and 7.9% among females. A history of sexual abuse was associated with alcohol consumption (p = 0.009), cigarette smoking (p = 0.001), and a history of transactional sex (p = 0.01). High/severe dental anxiety was significantly associated with increased odds of a history of sexual abuse (AOR = 1.81; 95% CI 1.10, 2.98), but not with caries experience (AOR = 0.66; 95% CI 0.15, 2.97) nor poor oral hygiene (AOR = 1.68; 95% CI 0.95, 2.96). Dental anxiety was associated with increased odds of alcohol intake (AOR = 1.74; 95% CI 1.19, 2.56), twice daily tooth brushing (AOR = 1.48; 95% CI 1.01, 2.17) and daily consumption of refined carbohydrates in-between-meals (AOR = 2.01; 95% CI 1.60, 2.54). Caries experience was associated with increased odds of using psychoactive substances (AOR = 4.83; 95% CI 1.49, 15.62) and having low socioeconomic status (AOR = 0.40; 95% CI 0.18, 0.92). Poor oral hygiene was associated with increased odds of having middle socioeconomic status (AOR = 1.43; 95% CI 1.05, 1.93) and daily consumption of refined carbohydrates in-between-meals (AOR = 1.38; 95% CI 1.08, 1.78).

CONCLUSION

Adolescents who are highly dentally anxious need to be screened for a history of sexual abuse to facilitate access to professional care and support.

Assessing the behavior management problems during the first dental visit of preschool children using a doll placement test

CONTEXT

Assessing dental anxiety as a predictor of the likely behavior of the child in the dental operatory is of paramount importance for a clinician to render quality care.

AIM

This study aims to correlate the dental anxiety of preschool children as shown during the doll placement test with that of their behavioral patterns during the first dental visit.

SETTINGS AND DESIGN

This cross-sectional study was conducted between the ages of 3-7 years.

MATERIALS AND METHODS

During their first dental visit, the background variables were elicited from parent/guardian at the reception desk. Later at the play area, the child was given a set of dolls representing dentist, child, and mother to place them in a model dental office having a dental chair. The child was then taken for the initial oral examination, during which the behavior of the child was rated using Frankl's Behavior Rating Scale. The data collected were analyzed using Chi-square test and binary regression analysis.

RESULTS

The observed association between the doll placement pattern and the behavior of the patient during dental treatment was statistically significant (P < 0.001). The binary regression analysis showed that the child's unpleasant previous medical and parent's unpleasant dental experiences had higher odds favoring uncooperative behavior (46.63 and 41.93, respectively).

CONCLUSIONS

The child's behavior on the dental chair is associated with the doll placement pattern, which is also influenced by experiences of the child during his/her encounter with the medical doctor and previous dental experiences of their parents.

Use of an animated emoji scale as a novel tool for anxiety assessment in children

Background

Dental anxiety in children is a major barrier in patient management. If dental anxiety in pediatric patients is assessed during the first visit, it will not only aid in management but also help to identify patients who are in need of special care to deal with their fear. Nowadays, children and adults are highly interested in multimedia and are closely associated with them. Children usually prefer motion pictures on electronic devices than still cartoons on paper. Therefore, this study was conducted to evaluate a newly designed scale, the animated emoji scale (AES), which uses motion emoticons/animojis to assess dental anxiety in children during their first dental visit, and compare it with the Venham picture test (VPT) and facial image scale (FIS).

Methods

The study included 102 healthy children aged 4–14 years, whose dental anxiety was measured using AES, VPT, and FIS during their first dental visit, and their scale preference was recorded.

Results

The mean anxiety scores measured using AES, FIS, and VPT, represented as mean ± SD, were 1.78 ± 1.19, 1.93 ± 1.23, and 1.51 ± 1.84, respectively. There was significant difference in the mean anxiety scores between the three scales (Friedman test, P < 0.001). The Pearson's correlation test showed a very strong correlation (0.73) between AES and VPT, and a strong correlation between AES and FIS (0.88), and FIS and VPT (0.69), indicating good validity of AES. Maximum number of children (74.5%) preferred AES.

Conclusion

The findings of this study suggest that the AES is a novel and child-friendly tool for assessing dental anxiety in children.

Dental anxiety in schoolchildren with molar incisor hypomineralization-A population-based cross-sectional study

BACKGROUND

Identifying patients with high levels of DA helps to define the most adequate oral healthcare strategy, especially for pediatric patients.

AIM

To investigate the association between parental reports of dental anxiety (DA) and molar incisor hypomineralization (MIH) in schoolchildren.

DESIGN

A cross-sectional study was conducted in a representative sample of 731 8-year-old schoolchildren from the city of Curitiba, Brazil, who were clinically examined (k ≥ 0.75) for the diagnosis of MIH and dental caries using the EAPD criteria and dmft/DMFT index, respectively. Parents/guardians reported children's DA using the Dental Anxiety Question (DAQ) and answered a self-administered structured questionnaire addressing socioeconomic and demographic characteristics. Associations were evaluated using Poisson regression analysis with robust variance (P < 0.05).

RESULTS

A significant association was found between DA and MIH (PR = 1.20; 95%CI: 1.01-1.42; P = 0.038), but this association lost its significance when adjusted for the other characteristics (PR = 1.13; 95%CI: 0.93-1.38; P = 0.215). Caries experience in primary teeth was associated with lower levels of DA (PR = 0.83; 95%CI: 0.71-0.96; P = 0.0013). The most recent visit to the dentist due to pain increased the levels of DA (PR = 1.18; 95%CI: 1.07-1.30; P = 0.001).

CONCLUSIONS

The presence of MIH in schoolchildren was not associated with parental reports of DA.

Effect of Verbal and Written Information and Previous Surgical Experience on Anxiety During Third Molar Extraction

PURPOSE

Third molar extraction is a quite common surgical procedure that causes dental anxiety. This procedure affects patients physiologically and mentally. The type of information provided to patients is important to determine the level of their anxiety regarding the surgical procedure. Patients' experience is also a major determinant of dental anxiety. It is subjective and perceived only by the patient. Questionnaires are tools used to determine and assess patient anxiety. The present study evaluated the effect of verbal and written information and the previous surgical experience of patients on their anxiety before and after third molar extraction.

PATIENTS AND METHODS

A total of 66 patients who had been admitted for third molar extraction under local anesthesia were included. The patients were divided into 3 groups: group 1 was given verbal information, group 2 was given written information, and group 3 had had previous surgical experience. The Spielberger State Anxiety Inventory (STAI-S), Dental Fear Scale (DFS), Modified Dental Anxiety Scale (MDAS), and visual analog scale (VAS) were used pre- and postoperatively to evaluate dental anxiety.

RESULTS

The MDAS and VAS scores of all patients had decreased postoperatively (P = .012 and P < .001, respectively). The postoperative MDAS and VAS scores were lower than the preoperative scores in women (P = .007 and P < .001, respectively). The postoperative MDAS (P = .014 and P = .004, respectively) and VAS (P < .001 and P = .002) scores had decreased compared with the preoperative scores in groups 2 and 3. The preoperative and postoperative MDAS and VAS scores were similar in group 1. In addition, the preoperative and postoperative STAI-S and DFS scores were similar in all groups.

CONCLUSIONS

All patients should be adequately informed about the third molar extraction procedure, even if they have previous experience. Providing detailed information reduced the postoperative anxiety of the patients.

Dental fear and its determinants in 7-11-year-old children in Tehran, Iran

AIM

To assess dental fear and its determinants in 7-11-year-old children.

METHODS

In this cross-sectional (descriptive-analytical) study, the standard Persian version of the Children's Fear Survey Schedule-Dental Subscale (CFSS-DS) questionnaire was completed by 240 parent-child (children aged 7-11 years) pairs referred to dental clinics in Tehran city, Iran. Background characteristics were also inquired.

RESULTS

An equal number of boys and girls participated in the study. The mean score of fear among the children was 21.66 ± 8.33. The causes of fear among the children were, first, injection, and then, seeing the dentist's drill, choking feeling, and finally, filling the tooth. There was a significant correlation between the scores of children's dental fear and their experience of meeting with the dentist (p = 0.001). The result of the regression test showed that the age of the children (p = 0.022) and high levels of dental fear among their fathers (p < 0.001) was related to high levels of dental fear among the children.

CONCLUSIONS

The present children revealed a moderate level of dental fear. Taking children's age into account in behavioural management and challenging father's fear seemed to play a key role to reduce the child's fear and prevent its long-term consequences.

Effect of visual distraction on children's anxiety during dental treatment: a crossover randomized clinical trial

AIM

This was to evaluate the effect of visual distraction on anxiety of children during dental treatment.

MATERIALS AND METHODS

This randomized, crossover clinical trial study was conducted on 28 children (aged 4-5 years) randomly divided into two groups of 14 each. Group 1, treatment procedure in the first visit was completed while the patients were watching a cartoon as a visual distraction tool, at the second visit, the procedure was carried out with conventional tell-show-do. Group 2, had visual distraction in their second visit and conventional tell-show-do during the first visit. Treatment procedures were similar in both groups during two sessions. The anxiety level was determined using Venham picture test and pulse rate (PR) at the beginning and the end of each appointment. Patient behaviour was also scored using Frankl behaviour rating scale (FBRS).

RESULTS

Self-reported dental anxiety was reduced significantly by visual distraction (p-value < 0.001) compared to conventional tell-show-do, but it did not change FBRS scores significantly (p-value = 0.24).

CONCLUSION

Use of visual distraction improves self-reported anxiety and decreases PR of children but does not change their behaviour.

A Randomized Controlled Trial Comparing Er:YAG Laser and Rotary Bur in the Excavation of Caries - Patients' Experiences and the Quality of Composite Restoration

Objective

The aim of this study was to evaluate patients´ experiences of two excavation methods, Er:YAG laser and rotary bur and time required by the methods as well as objective assessments of quality and durability of restorations over a two-year period.

Methods

A prospective, single-blind, randomized and controlled investigation was performed. Patients aged 15 to 40 years with at least two primary caries lesions, which had been radiographically assessed as of the same size, were recruited. In each patient, one cavity was excavated using rotary bur and one using Er:YAG laser technique. The time required for excavations and, where applicable, local anaesthesia, was measured during the treatments. Patient experiences were measured using questionnaires. The quality and durability of restorations were assessed over a two-year period in accordance with modified Ryges criteria and radiographs. Twenty-five patients (mean age 22.6 years) participated in the study. In total, 56 cavities were included of which 28 were treated with Er:YAG laser and 28 were treated with a rotary bur.

Results

The patients associated the laser method with less discomfort. The mean time for excavation by laser was three times longer than by rotary bur (13.2 min vs. 4.3 min, P<0.0001). Over a two-year period, no statistically significant differences with regard to quality or durability could be seen between the restorations associated with the methods.

Conclusion

The Er:YAG laser technique was more time-consuming than the rotary bur. Despite this, the laser technique caused less discomfort and was preferred as an excavation method by patients.

A Cross-sectional Study to assess the Perception of Psychosocial Elements among Pediatric Patients visiting Dental Clinics

INTRODUCTION

Children with high dental fear and perception usually encounter high prevalence of dental caries. Data showed that individuals with dental fear will probably defer dental appointments which may result in the formation of a setup of an endless loop of dental fear. Present study was aimed to assess different psycho-social parameters among pediatric patients visiting dental clinics.

MATERIALS AND METHODS

In the present cross-sectional study, the data of 200 schoolchildren were collected and analyzed by means of a questionnaire. Evaluation of the oral health status was done by experienced pedodontists. All the answers were recorded and analyzed by Statistical Package for the Social Sciences (SPSS) software.

RESULTS

Nearly 120 were regular attendees while remaining 80 were found to be irregular attendees. Significant difference was observed while comparing the decayed, missing, and filled teeth (DMFT) index, decayed teeth, dental fear, cognitive vulnerability, and dental prevention belief between the regular and irregular group. Significant correlation was observed between higher number of decayed teeth and increasing level of dental fear.

CONCLUSION

Various psychosocial parameters, by affecting the dental visits, are associated with outcome of oral health measures.

CLINICAL SIGNIFICANCE

Special attention should be paid to the pediatric patients with such kind of behavior so that their psy-chosocial attitude could be modified in favor of dental treatment.

The Dental Anxiety Scale and Effects of Dental Fear on Salivary Cortisol

Only a few studies have investigated use of the Dental Anxiety Scale in dental fear-induced neuroendocrine changes. The present study examined 19 female patients, each at two timepoints across an educational and a treatment session within a periodontitis therapy. Subjective measures included a visual analogue scale, the STAI State scale, and the Dental Anxiety Scale. Salivary cortisol was measured in parallel across all four timepoints. Although patients were significantly more aroused and anxious prior to the treatment session, salivary cortisol remained unchanged. However, patients with high Dental Anxiety were significantly more aroused and anxious and showed significantly higher salivary cortisol during the educational session than those with low scores on Dental Anxiety. In conclusion, the Dental Anxiety Scale differentiated mean neuroendocrine change between patients scoring low and high for Dental Anxiety and its use as an accurate tool to identify patients with high dental anxiety should be further studied predictively.

Assessing the Attitudes and Clinical Practices of Ohio Dentists Treating Patients with Dental Anxiety

Dental anxiety (DA) negatively affects patients' oral and overall health. This study explored attitudes and clinical practices of licensed Ohio general dentists who treat patients with DA. Methods: An anonymous self-administered mail survey was sent to 500 general dentists licensed and practicing in Ohio. Responses to 21 pre-coded questions were analyzed. Frequencies were examined; cross-tabs, Chi-Square, and Fischer's Exact Test were calculated for statements according to dentists' gender. Alpha was set at p = 0.05. Results: Nearly all respondents treated anxious patients; males were more likely to find it challenging than females. Dentists were most familiar with distraction, although half found nitrous oxide to be an effective tool. Female dentists were more likely than males to be familiar with anxiolytics and find them effective. Conclusion: Overall, Ohio general dentists are most familiar with using distraction and nitrous oxide during appointments for anxious patients. Gender differences exist in attitudes towards anxiolytic use for patients with DA.

PRACTICE IMPLICATIONS

By identifying techniques that are comfortable for patient and practitioner, oral health disparities associated with DA may be reduced.

Ambivalence in Coping with Dental Fear and Avoidance: A Qualitative Study

Dental phobia is a widespread problem, which can have significant impact on the individual’s health and daily life. This grounded theory study aims to explore the situation of dental phobic patients: how dental phobia interferes with their normal routines and functioning, social activities and relationships, what factors contribute to the maintenance of dental fear and how they cope with their fear. In the qualitative analysis of thematized in-depth interviews four main categories were developed: threat to self-respect and well-being, avoidance, readiness to act and ambivalence in coping. The results show that several psychological and social factors interact in determining how dental phobic individuals cope with their fear, and demonstrate in what way dental fear affects their daily lives.

Reliability and Validity of the Modified Dental Anxiety Scale in Turkish Patients

We aimed to determine dental anxiety among Turkish patients and assess the sensitivity, specificity, positive/negative predictive values and reliability of the Modified Dental Anxiety Scale (MDAS) and Corah's Dental Anxiety Scale (DAS). Patients referred to our clinic for dental treatment who had a history of dental anxiety were included in the study. 294 randomly selected patients (mean age 38.8 years) completed a questionnaire combining Corah's DAS and MDAS. They were retested 15 days later. The prevalence of dental anxiety was found to be 9.9% (29/294) for Corah's DAS at the cut-off point ≥ 15 and 8.8% (26/294) for the MDAS at the cut-off point ≥ 19. Both dental anxiety scales gave acceptable sensitivity, specificity, positive and negative predictive values at these cut-off points.

Associations between dental anxiety, sense of coherence, oral health-related quality of life and health behavior--a national Swedish cross-sectional survey

Background

Dental anxiety (DA) is a common condition associated with avoidance of dental care and subsequent health-related and psychosocial outcomes, in what has been described as the vicious circle of DA. Also, recent studies have found an association between the psychosocial concept of sense of coherence (SOC) and DA. More studies are needed to verify the relationship between DA and SOC, especially using population-based samples. There is also a need for studies including factors related to the vicious circle of DA, such as oral health-related quality of life (OHRQoL), in order to further establish the correlates of DA in the general population. Therefore, the aim of this study was to investigate the relationship between DA and SOC, OHRQoL and health-related behaviour in the general Swedish population.

Methods

The survey included a randomly selected sample of the adult Swedish population (N = 3500, age 19 – 96 years.). Data was collected by means of telephone interviews. Dental anxiety was measured with a single question. The SOC measure consisted of three questions conceptualising the dimensions of the SOC: comprehensibility, manageability and meaningfulness. The data collection also included the five-item version of the Oral Health Impact Profile (OHIP-5), as a measure of OHRQoL, as well as questions on oral health-related behaviour and socioeconomic status. Statistical analyses were made with descriptive statistics and inference testing using Chi-square, t – test and logistic regression.

Results

High DA was associated with low OHRQoL, irregular dental care and smoking. There was a statistically significant relationship between the SOC and DA in the bivariate, but not in the multivariate, analyses. Dental anxiety was not associated with oral health-related behaviour or socioeconomic status.

Conclusions

This cross-sectional national survey gives support to the significant associations between high dental anxiety, avoidance of dental care and health-related outcomes, which may further reinforce the model of a vicious circle of dental anxiety. The results further indicate a weak relationship between dental anxiety and sense of coherence.

Reporting of dental status from full-arch radiographs: Descriptive analysis and methodological aspects

AIM: To identify standards, how entities of dental status are assessed and reported from full-arch radiographs of adults.

METHODS: A PubMed (Medline) search was performed in November 2011. Literature had to report at least one out of four defined entities using radiographs: number of teeth or implants; caries, fillings or restorations; root-canal fillings and apical health; alveolar bone level. Cohorts included to the study had to be of adult age. Methods of radiographic assessment were noted and checked for the later mode of report in text, tables or diagrams. For comparability, the encountered mode of report was operationalized to a logical expression.

RESULTS: Thirty-seven out of 199 articles were evaluated via full-text review. Only one article reported all four entities. Eight articles reported at the maximum 3 comparable entities. However, comparability is impeded because of the usage of absolute or relative frequency, mean or median values as well as grouping. Furthermore the methods of assessment were different or not described sufficiently. Consequently, established sum scores turned out to be highly questionable, too. The amount of missing data within all studies remained unclear. It is even so remissed to mention supernumerary and aplased teeth as well as the count of third molars.

CONCLUSION: Data about dental findings from radiographs is, if at all possible, only comparable with serious limitations. A standardization of both, assessing and reporting entities of dental status from radiographs is missing and has to be established within a report guideline.

A randomized controlled trial of the effect of a brief cognitive-behavioral intervention on dental fear

OBJECTIVES

The objective of this study was to examine the effect of a brief cognitive-behavioral intervention for patients with dental fear in a private dental clinic.

METHODS

Patients presenting with subjectively reported dental fear were randomly assigned to either an immediate intervention (n = 53) or a waiting list (n = 51) group. Both groups received an identical intervention, but delayed by 4-6 weeks in the waiting list group. Participants were asked to fill out two self-report questionnaires of dental fear at pre- and post-intervention, and again at a 2-year follow-up assessment.

RESULTS

Analysis of variance showed that dental fear was significantly reduced in the immediate intervention group (d = 1.5-2.2), compared with the waiting list group (d = 0.3-0.4). Additionally, all participants showed a significant reduction of dental fear following the brief intervention, and in the subgroup available for follow-up, this effect was maintained after 2 years.

CONCLUSIONS

This indicates that a brief cognitive-behavioral intervention may be efficacious in helping a significant number of patients with dental fear return to regular dental treatment. Future research should investigate the applicability of a brief cognitive-behavioral intervention in the dental clinic.

Behavioral changes in preschoolers treated with/without rotary instruments

BACKGROUND

Behavioral dentistry is an interdisciplinary science which needs to be learned, practiced, and reinforced in order to provide quality dental care in children.

AIM

To assess the anxiety experienced during dental treatment in preschool children with/without rotary instruments using behavioral scale.

STUDY AND DESIGN

Sixty pediatric patients of preschool age with bilateral occlusal carious lesions extending into dentin were selected for the study. Carious lesions were removed using conventional rotary instruments on one side and Papacarie - chemomechanical caries removal of approach on contra lateral side. Both cavities were restored with glass ionomer cement (Fuji IX). Anxiety scores were determined using 'Modified Child Dental Anxiety Scale' (Wong et al, 1998) during the various clinical stages of the treatment course.

RESULTS

Children experienced relaxed behavior when subjected to Papacarie method of caries removal compared to conventional method using rotary instruments.

CONCLUSION

This study helped us to provide behavioral measures and introduce children to dentistry in a nonthreatening setting.

Explanation and causal reasoning: A contribution to the interpretation of competing explanatory claims

The aim of this study is to attain a better understanding of the relationship between competing or complementary scientific explanatory claims. First, six different ways of approaching explanatory claims are briefly described and found, in part, to be unsatisfactory. It is argued that they should be supplemented by an analysis of underlying and sometimes partly unacknowledged causal presuppositions. This approach could be termed a causal analytical investigation, and in order to demonstrate its potential, it is applied to a concrete example: research into dental anxiety. The analysis shows that seemingly competing or complementary explanatory claims here neither compete with nor complement each other; instead, the analysis demonstrates that they explain different things. We then broaden the picture by discussing the relationship between aetiology and treatment. Finally we argue in favour of the general applicability of the approach and its relevance to science in general and to science-based practice.

On the dynamics of dental fear: dental or mental?

This study explored possible predictors of change over time in dental fear. In a population-based sample of 664 women, 38-54 yr of age at first assessment, a self-rating of dental fear was recorded on two occasions, 6 yr apart. Whilst the majority of the women maintained their level of fear, two subgroups reported changes at follow up. Of the 99 subjects indicating high fear at baseline, 54 recorded no or minimal fear at follow up and, among the 565 recording minimal fear at baseline, 27 reported increased fear at follow up. We used psychological and odontological findings at baseline to compare the four subgroups with altered or maintained fear ratings at follow up. The women reporting reduced fear at follow up differed significantly in the psychological variables from those reporting unchanged fear; there were no significant differences between these groups in any of the odontological variables. The group indicating increased fear at follow up did not differ from those with a maintained fearlessness in any of the baseline measurements. The results are discussed in terms of a systems-oriented understanding of the development of dental fear.

Psychological treatment of dental anxiety among adults: a systematic review

The aim was to investigate the efficacy of behavioural interventions as treatment of dental anxiety/phobia in adults, by conducting a systematic review of randomized controlled trials (RCTs). The inclusion criteria were defined according to the Patients, Interventions, Controls, Outcome (PICO) methodology. The study samples had documented dental anxiety, measured using validated scales [the Dental Anxiety Scale (DAS) or the Dental Fear Survey (DFS)], or fulfilled the psychiatric criteria for dental phobia. Behavioural interventions included were based on cognitive behavioural therapy (CBT)/behavioural therapy (BT), and control conditions were defined as information, sedation, general anaesthesia, and placebo/no treatment. The outcome variables were level of dental anxiety, acceptance of conventional dental treatment, dental treatability ratings, quality of life and oral health-related quality of life, and complications. This systematic review identified 10 RCT publications. Cognitive behavioural therapy/behavioural therapy resulted in a significant reduction in dental anxiety, as measured using the DAS (mean difference = -2.7), but the results were based on low quality of evidence. There was also some support that CBT/BT improves the patients' acceptance of dental treatment more than general anaesthesia does (low quality of evidence). Thus, there is evidence that behavioural interventions can help adults with dental anxiety/phobia; however, it is clear that more well-designed studies on the subject are needed.

Dental fear and anxiety in children and adolescents: qualitative study using YouTube

Background

Dental fear and anxiety (DFA) refers to the fear of and anxiety towards going to the dentist. It exists in a considerable proportion of children and adolescents and is a major dilemma in pediatric dental practice. As an Internet social medium with increasing popularity, the video-sharing website YouTube offers a useful data source for understanding health behaviors and perceptions of the public.

Objective

Using YouTube as a platform, this qualitative study aimed to examine the manifestations, impacts, and origins of DFA in children and adolescents from the public’s perspective.

Methods

To retrieve relevant information, we searched YouTube using the keywords “dental fear”, “dental anxiety”, and “dental phobia”. Videos in English expressing a layperson’s views or experience on children’s or adolescent’s DFA were selected for this study. A video was excluded if it had poor audiovisual quality, was irrelevant, was pure advertisement or entertainment, or contained only the views of professionals. After the screen, we transcribed 27 videos involving 32 children and adolescents, which were reviewed by a panel of 3 investigators, including a layperson with no formal dental training. Inductive thematic analysis was applied for coding and interpreting the data.

Results

The videos revealed multiple manifestations and impacts of DFA, including immediate physical reactions (eg, crying, screaming, and shivering), psychological responses (eg, worry, upset, panic, helplessness, insecurity, resentment, and hatred), and uncooperativeness in dental treatment. Testimonials from children, adolescents, and their parents suggested diverse origins of DFA, namely personal experience (eg, irregular dental visits and influence of parents or peers), dentists and dental auxiliaries (eg, bad manner, lack of clinical skills, and improper work ethic), dental settings (eg, dental chair and sounds), and dental procedures (eg, injections, pain, discomfort, and aesthetic concerns).

Conclusions

This qualitative study suggests that DFA in children and adolescents has multifaceted manifestations, impacts, and origins, some of which only became apparent when using Internet social media. Our findings support the value of infodemiological studies using Internet social media to gain a better understanding of health issues.

Oral health, sense of coherence and dental anxiety among middle-aged women

AIMS

The specific aims of this investigation were to analyze the relationship between sense of coherence (SOC), dental anxiety (DA) and oral health status among middle-aged women, measured both subjectively and objectively and adjusted for socioeconomic status (SES).

MATERIALS AND METHODS

Randomly selected women, 38 (n = 206) and 50 (n = 287) years of age, were included in a cross-sectional health examination. The participants underwent a series of examination stages, including a clinical and dental radiographic examination. The women responded to questionnaires concerning SES, oral health, DA and SOC.

RESULTS

The number of teeth was significantly related to SOC, where more missing teeth revealed a lower SOC level among 50-year-olds. The variables of caries, apical periodontitis and filled surfaces were not statistically significantly associated with SOC. However, the self-reported measure of oral health was associated with SOC in both age groups. High DA was significantly related to self-perceived poor oral health regardless of age. Individuals with high DA also had fewer teeth, more filled surfaces and more approximal caries. The multivariate models showed that higher SOC levels were associated with better oral health, as estimated by objective or subjective measures, while the inverse results were seen for DA. Thus, individuals reporting high DA were more likely to have fewer teeth and poor perceived oral health, taking SES into account.

CONCLUSIONS

Sense of coherence and dental anxiety are psychological aspects with respect to health- and risk-factors of oral health.

Oral health-related quality of life, sense of coherence and dental anxiety: an epidemiological cross-sectional study of middle-aged women

BACKGROUND

Few publications report on the relationship between salutogenesis, as measured by the concept of sense of coherence, and oral health-related quality of life. Even less information is to be found when the behavioural aspect of dental anxiety is added. The aim of the present study was to evaluate how oral health-related quality of life is related to sense of coherence and dental anxiety.

METHOD

The study had a cross-sectional design and included 500 randomly selected women in Gothenburg, Sweden, 38 and 50 years of age, from health examinations in 2004-05. The survey included questionnaires covering global questions concerning socio-economic status, oral health/function and dental care behaviour, and tests of oral health-related quality of life, sense of coherence, and dental anxiety.

RESULTS

High dental anxiety and low sense of coherence predicted low oral health-related quality of life. In addition, socioeconomic status as measured by income, perceived oral functional status as captured by chewing ability and self-reported susceptibility to periodontal disease were also important predictors of oral health-related quality of life.

CONCLUSION

Dental anxiety and sense of coherence had an inverse relationship with regard to oral health-related quality of life. These associations were stronger than other risk factors for low oral health-related quality of life.

Dental anxiety in relation to neuroticism and pain sensitivity. A twin study

Predisposing personality traits as well as heightened pain sensitivity and fear of pain have been hypothesized as central factors in the development of dental anxiety. The aim of the study was to estimate the heritability of dental anxiety, and to investigate the genetic and environmental sources of covariance between dental anxiety on one hand, and pain sensitivity and the neuroticism trait on the other. A sample comprising 188 twins, aged 23-35 years (53 monozygotic and 39 dizygotic twin pairs, and 4 single twins whose co-twin did not participate), was included in the study. Measures of dental anxiety and personality were obtained using Corah's Dental Anxiety Scale and the NEO Personality Inventory Revised, respectively. Heat pain and cold pressor pain sensitivity were assessed using standard pain testing procedures. Bivariate Cholesky models were employed to decompose the correlations between phenotypes into genetic and environmental factors. Using models with common additive genetic (A) and individual-specific environmental (E) factors, moderate heritability (i.e., .41) for dental anxiety was demonstrated. Virtually all of the phenotypic correlation between neuroticism and dental anxiety could be accounted for by A. Furthermore, a substantial part of the variance in dental anxiety was due to specific genetic and individual environmental influences unrelated to neuroticism. The phenotypic correlations between dental anxiety and the pain sensitivity indices were close to zero. Thus, while neuroticism and dental anxiety share a sizeable proportion of genetic (but not environmental) risk factors, the results also suggest that these two attributes are distinct entities with overlapping, but not identical, etiologies.

Factors of importance to maintaining regular dental care after a behavioural intervention for adults with dental fear: a qualitative study

OBJECTIVE

Dental phobia is prevalent in the general population and can be successfully treated through cognitive behavioural therapy, which results in patients being able to cope with dental treatments. The aim of this study was to increase the understanding of factors of importance for maintaining regular dental care after completion of a cognitive behavioural therapy programme.

MATERIAL AND METHODS

A qualitative study design was used. Fourteen individuals who had successfully completed the programme and had thereafter been referred to a general dental practitioner were interviewed. An interview guide with open-ended questions was used. The interviews were tape-recorded and transcribed verbatim. The texts were analysed using descriptive and qualitative content analysis (Grounded Theory).

RESULTS

The manifest analysis identified four content areas: experience of dental care, content of the behavioural therapy programme, perception of therapy and impact on quality of life. The latent analysis identified influence on quality of life, security, activity and barriers to dental care as categories. Although all informants had successfully completed the dental fear treatment programme, only a few stated that they had an uncomplicated relation to dental care afterwards. Barriers to dental care were lack of money and fear. A sense of security was conclusive to coping with dental care, and a respectful approach on the part of the dental care personnel was essential to development of this sense.

CONCLUSIONS

Confidence in one's own ability to cope with dental care and the right to guide the treatment were important. Thus the theme in the present study was self-efficacy and respectful dental care personnel.

Oral health and its influence on cognitive behavioral therapy in patients fulfilling the Diagnostic and Statistical Manual of Mental Disorders-IV criteria for intra-oral injection phobia

OBJECTIVE

To describe self-perceived and clinically assessed oral health and oral treatment needs among intra-oral injection-phobic patients (Diagnostic and Statistical Manual of Mental Disorders-IV) and to explore whether these factors have an impact on the outcome of cognitive behavioral therapy (CBT).

MATERIAL AND METHODS

Fifty-five patients (43 women, mean age 32.5 years, range 18-62 years) were treated with short-duration CBT. Dental anxiety (Dental Anxiety Scale and Dental Fear Survey) and self-perceived oral health were assessed by means of questionnaires. Three dentists assessed oral health by means of clinical examination and radiographs. Treatment outcome was measured by ability to receive an intra-oral injection by a general dentist within a 1-year follow-up (FU) period or ability to complete a behavioral avoidance test (BAT) at FU, and changes in dental anxiety and positive and negative thoughts from pretreatment to FU.

RESULTS

Forty percent of patients ranged their oral health as "good" or "very good". Mean decayed teeth (DT) was 2.2 (range 0-15). The total number of teeth in need of treatment, periodontal treatment, endodontic treatment and extractions ranged from 0 to 15, 0 to 19, 0 to 4 and 0 to 5, respectively. Self-rated oral health correlated significantly with clinical oral health. The outcome of CBT in terms of being able to receive a dental injection during FU was not influenced by oral health status. However, correlation analyses indicated that patients with the poorest oral health had the greatest increase in positive thoughts and the greatest decrease in negative thoughts from pretreatment to FU.

CONCLUSIONS

The oral health of intra-oral injection-phobic patients varies substantially, but is comparable to that of the normal population. Coping with a dental injection after CBT is not influenced by oral health and treatment needs.

Anxiety and quality of life in phobic dental patients

Little is known about the anxiety patients experience before attending for dental treatment. The aim of this study was to determine, in dentally phobic patients, the temporal relationship of pre-operative anxiety levels, and the disruption to daily life caused by this. Twenty-four phobic and 19 comparison (non-phobic) dental patients were recruited. Four validated questionnaires were used to assess anxiety and quality of life, which each patient completed for 5 days prior to, and on the day of, treatment. Those in the experimental group were found to have significantly greater levels of dental and general anxiety, and a significantly lower quality of life compared with those in the comparison group. Significant temporal relationships were found with all of the questionnaires. Dental and general anxiety scores were significantly correlated with quality-of-life measures. This study suggests that phobic dental patients are experiencing significant increased anxiety, and significant negative quality-of-life effects, in this period.

Dental avoidance behaviour in parent and child as risk indicators for caries in 5-year-old children

AIM

The aim of this study was to explore associations between avoidance behaviour and dental anxiety in both parents and children and caries experience in 5-year-old children. It was hypothesised that parents' dental avoidance behaviour and dental anxiety were related to dental caries in 5-year-old children.

DESIGN

Data were collected from dental records and by clinical and radiographic examination of 523 children. The parents completed a questionnaire regarding education, national background, dental anxiety, dental attendance, and behaviour management problems. Bivariate and multivariate logistic regression was conducted.

RESULTS

Children having one or more missed dental appointments (OR = 4.7), child behaviour management problems (OR = 3.3), child dental anxiety (OR = 3.1), and parents avoiding dental care (OR = 2.1) were bivariately associated with caries experience at the age of 5 years. In multivariate logistic regression, having one or more missed dental appointments (OR = 4.0) and child behaviour management problems (OR = 2.4) were indicators for dental caries in 5-year-old children, when controlling for parents education and national origin.

CONCLUSION

Parents that avoid bringing their child to scheduled dental appointments and previous experiences of behaviour management problems for the child indicated risk for dental caries in 5-year-old children.

Oral health and oral treatment needs in patients fulfilling the DSM-IV criteria for dental phobia: Possible influence on the outcome of cognitive behavioral therapy

OBJECTIVE

To describe oral health and oral treatment needs in a group of dental phobic patients (DSM-IV) and to explore possible relationships between these factors and changes in self-reported dental anxiety before and after phobia treatment.

MATERIAL AND METHODS

Forty patients (25 women) fulfilling the DSM-IV criteria for specific phobia were included in the study. Mean age of the group was 34.9 years (range 19-60) and mean dental avoidance was 11.2 years (range 3-30 years). They were treated with cognitive behavioral therapy (CBT) during either one session (3 h) or five sessions (1 h each). Oral health was evaluated by orthopantomogram and clinical examination. The outcome of the CBT was measured by the change in dental anxiety scores (DAS, DFS) and in positive and negative thoughts during a standardized dental behavior test from pretreatment to 1-year follow-up.

RESULTS

Mean (SD) DMFT was 16.5 (5.8), range 3-26; DT was 6.6 (4.2). Mean number of teeth with dental treatment need (restorative, periodontal, extractions, etc.) was 9.6 (6.9), range 1-28. There were statistically significant correlations between number of decayed teeth and decrease in negative thoughts (r=-0.39, p=0.048) and maximum anxiety (r=-0.65, p=0.001). The total number of teeth with treatment need correlated with an increase in positive thoughts (r=0.60, p=0.001) and decrease in maximum anxiety (r=0.50, p=0.015).

CONCLUSIONS

There are large variations in oral health and treatment needs among patients fulfilling the DSM-IV criteria for dental phobia. Patients with the best dental health and lowest treatment needs experience the largest increase in positive cognitions during exposure to dental treatment at 1-year follow-up.

Psychological characteristics of Norwegian adolescents reporting no likelihood of visiting a dentist in a situation with toothache

OBJECTIVES

The aim of the present study was to explore and compare psychological characteristics in two groups of 18-year-old adolescents: (i) subjects reporting no likelihood of visiting the dentist in a situation with toothache (avoiders); and (ii) subjects who definitely would see the dentist in the same situation (non-avoiders).

METHODS

The study included a representative sample (n = 1385) of 18-year-old adolescents attending high schools in the county of Hordaland, Norway. Data were collected by use of questionnaires completed in classrooms.

RESULTS

The following factors increased the risk of being included in the avoider group: negative beliefs of the dentist (communication, trust and control) (OR = 4.3), high dental anxiety (OR = 3.5), and being a male (OR = 2.4). No predictive power for being included in the avoider group was found for general self-efficacy, coping style, multiple fears, or anxiety and depression.

CONCLUSIONS

Adolescents with avoidance behaviour have more negative beliefs of the dentist and higher dental anxiety compared to non-avoiders, but were found to have no other specific psychological characteristics. These results indicate a high potential for prevention of future avoidance of care for dentists that are focusing on patient communication and to give young patients perceptions of trust and control during dental treatment.

Giving low priority to oral health care. Voices from people with disabilities in a grounded theory study

OBJECTIVE

Our knowledge of how people with disabilities look upon oral health and dental care is limited. The aim of this study was thus to explore how the people with disabilities experience the encounter with dental health care.

MATERIAL AND METHODS

With a focus on dental care and oral health, qualitative interviews with 16 informants with cognitive and/or physical disabilities were analysed in accordance with the qualitative method of grounded theory.

RESULTS

A core category identified and labeled "giving low priority to oral health care" was found to be related to four other categories: "being afraid of losing control", "having difficulties complying with instructions", "having a desire for continuity", and "wishing to be just like everyone else". The results show that oral health and dental care are important, but are not considered a priority by the people with disabilities. General health issues have much higher priority but do not include oral health, which consequently can affect oral health negatively.

CONCLUSIONS

Of several factors identified that could be improved to make dental visits more pleasant for patients are enhancing a sense of control in the patient and improving continuity.

Current state of sedation/analgesia care in dentistry

PURPOSE OF REVIEW

Dentistry treatment is one of the most anxiety-inducing events in people's lives. The development of pain and anxiety-control techniques has always been very closely aligned to the development of dentistry. The purpose of this review is to summarize the recent literature in this field.

RECENT FINDINGS

The literature in the last 12 months falls into four main categories: dental anxiety and its influence on patient care, dental sedation for children, sedation with benzodiazepines for dentistry, and intravenous propofol sedation for dentistry.

SUMMARY

Considerable progress is being made with a number of innovative techniques. Oral midazolam for children and patient-controlled propofol show very promising results. More research is needed before propofol can be recommended for use without anaesthetic staff. The recently published systematic review of sedation in children outlines gaps in the literature and contains recommendations for future work.

Consequences of childhood sexual abuse experiences on dental care

OBJECTIVE

Around 20% of female patients seeking dental care may have experienced childhood sexual abuse (CSA). Several similarities between abuse situations and dental treatment lead to dental fear. Since dental fear hampers oral health, the long-term effects of CSA on dental care and the specific factors that lead to increased stress during dental treatment have been investigated in women exposed to CSA.

METHODS

A self-administered questionnaire, which was developed to investigate the objectives of the study, was distributed to 111 women recruited from support centers for women with CSA experiences. CSA was explored with a modified version of the questionnaire developed by Wyatt. Data from 85 women with CSA experiences were used for comparison to the data of 170 matching control women recruited, who were mothers of children attending kindergarten.

RESULTS

Compared to controls, women exposed to CSA exhibited several long-term effects on dental care in terms of major psychological strain during dental treatment (36.5%/18.8%; P<.005), a lower number of prophylactic controls (72.9%/89.4%; P<.005), and preference for a female dentist to a male dentist (29.4%/8.2%; P<.0001). Women with CSA experiences considered four of five defined stressors associated with dental treatment as more intense. Of these women, 28% suffered from memories of their original abuse situations during dental treatment, and 29.4% believed that the dentist should have known about their history of abuse.

CONCLUSION

CSA experiences may increase psychological strain during dental treatment. To improve dental care for women exposed to CSA, dentists should adjust their treatment plans to the specific needs of these patients.

Oral health in rural and remote Western Australian Indigenous communities: A two-year retrospective analysis of 999 people

AIM

Remoteness is a significant factor determining the level of basic health, education and infrastructure services to which Aboriginal people have access. This study examines the oral health status and oral health behaviours of Aboriginal people attending rural and remote dental clinics.

METHODS

Data were collected as part of routine delivery of dental services in five rural and remote dental clinics.

RESULTS

The average DMFT score of patients in all the clinics was 8.5 (sd 6.6). Advanced periodontal disease (a CPI score of 3 and/or 4) was present in 60.8% of all patients. Almost 88% of patients had experienced toothache in the previous six months. Almost a third (31.4%) of people could not remember the last time they went to the dentist. Less than half of the people reported brushing their teeth daily (40.4%) with 37.9% cleaning occasionally. A total of 52.4% of patients identified themselves as a 'smoker' of tobacco products. Past smokers accounted for 10.5% of the participants. The most common self-reported reason for visiting the clinic was for 'hole in tooth/fillings required' (37.4%), followed by 'pain/urgent problem' (24.8%).

CONCLUSIONS

This study emphasises the urgent need for the development of strategies targeting Aboriginal oral health, both as stand alone, and as part of a multifactorial risk factor approach where oral health is integral to general health activities.

Dental anxiety--an epidemiological study on its clinical correlation and effects on oral health

Pronounced dental anxiety could lead to avoidance strategies to evade dental visits. The aim of the present epidemiological study was to investigate the prevalence and related oral disease patterns of dental anxiety in young adult male soldiers. Therefore, the intensity and frequency of dental anxiety are presented and the correlation with oral clinical findings are evaluated. Three hundred seventy-four soldiers who underwent a compulsory dental check-up were randomly assigned to this study. Psychological parameters were collected based on a protocol integrating the Dental Anxiety Scale (DAS) and the Gatchell Fear Scale (GaFS). Patient-based measures included D3,4MF-scores for dental status and the Community Periodontal Index of Treatment Need (CPITN) for periodontal status. Thirty-two individuals (8.6%) showed DAS-scores of 13 or 14 (anxious), while 4.6% had a DAS-score > or = 15 (highly anxious/phobic). Highest DAS-values were measured among patients' aged 19-29 (n = 262). DMFS-values of anxious and less anxious patients showed only minor differences. However, anxious patients had significantly more carious lesions (P < 0.001). CPITN periodontal values showed no significant differences between both groups. 89.2% of less anxious individuals and 79.6% of anxious patients went for regular dental check-ups. Thus, every tenth patient was considered to have high dental anxiety. Anxiety results in avoidance behaviour, which can only be discovered upon compulsory examinations and which is associated with higher caries morbidity and need for oral rehabilitation. As anxiety has a direct influence on oral health, it should be detected and accounted for in a treatment concept integrating dental and cognitive-behavioural therapeutic approaches.
