Modified Corah Dental Anxiety Scale Research Articles

Dental anxiety and oral health-related quality of life before and after non-surgical periodontal treatment.

To (1) investigate dental anxiety (DA) and oral health-related quality of life (OHRQOL) before and after non-surgical periodontal treatment (NSPT) and (2) determine correlations between these patient-reported measures. Demographics, smoking habits, dental pain, Modified Corah's Dental Anxiety Scale (MDAS), and Oral Health Impact Profile (OHIP-14) were assessed in eighty-two participants. Mean age was 48.3years ± 11.5. At baseline, 8.5% reported being active smokers. Of non-smokers, 11% reported being an ex-smoker. After NSPT, 11.0% reported smoking. Patients' maximal pain in the last month decreased after therapy. Before treatment, participants reported higher DA. Extreme DA was observed in 8.5% of participants before therapy. Afterwards, 2.4% of participants reported extreme DA. Fear of having a foreign object in the mouth decreased after NSPT. All OHIP-14 scores, except functional limitation, improved post-treatment. Higher DA was associated with worse OHRQoL before treatment. After treatment, total MDAS score was associated with OHIP-14 global score, physical pain, psychological disability, and social disability. Worse MDAS sub-scores were associated with a higher OHIP-14 global score. Individuals with "normal/slight anxiety" had a significant improvement in OHRQoL, whereas people in the "moderate and extreme anxiety" group did not report a significant improvement. Patients diagnosed with generalized periodontitis (GP) stage III grade B and GP stage IV grade B reported less anxiety after NSPT. Associations of MDAS subcategories with OHIP-14 domain scores were found before and after therapy. DA decreases and OHRQoL enhances after NSPT in patients with "normal/slight" anxiety to dental treatment. Dental practitioners should plan strategies to cope with anxiety to dental treatment and prevent decreases in OHRQoL. Within the limitations of this study, DA and OHRQoL were positively correlated in patients with periodontitis, before and after NSPT, using the MDAS and OHIP-14 questionnaires. The results of our study suggest that treatment is effective in terms of alleviating DA and improving oral health, along with quality of life, in patients that report "normal/slight" anxiety to dental treatment. Nonetheless, results must be interpreted with caution since patients are generally anxious before any type of dental treatment. DA may not just be confined to NSPT per se. According to our results, evaluation of both outcomes should be an integral part of routine periodontal clinical evaluation and periodontal reevaluation of initial therapy. It is important that clinicians learn to identify patients that suffer from anxiety and take time to explain the treatment procedures to the patient, to strive for patient's emotional well-being before, during, and after dental care services. The use of specific questionnaires for both DA and OHRQoL may be more appropriate to demonstrate the psychological and quality of life differences due to periodontal disease and NSPT.

Anxiety among patients undergoing various dental procedures.

Dental Anxiety (DA) was the most frequent problem which can lead to the avoidance of treatment. Therefore, is to evaluate the DA level among patients of different treatments. A questionnaire was distributed among the participants. The Modified Corah Dental Anxiety Scale (MDAS) was used to measure dental anxiety. In gender differences, it has been found that females were more anxious than male participants. The younger age group (18-30 years) was less anxious than the older age groups (P < 0.05). Most of the participants in all conditions were slightly anxious. Male participants exhibited less dental anxiety than females. This might be due to males being more stable emotionally.

Preoperative online intervention to dental anxiety in patients with transcrestal sinus floor elevation.

Dental anxiety (DA) is a frequent and widespread phenomenon worldwide. There are few studies that have discussed the preoperative intervention of dental anxiety. The aim of this study was to explore the clinical efficacy of an online intervention to improve understanding and reduce dental anxiety in patients with transcrestal sinus floor elevation (TSFE) and to explore the correlation between patients' understanding and dental anxiety, pain perception, and satisfaction. This prospective randomized controlled trial enrolled patients who underwent TSFE and simultaneous implant placement. Patients were randomly allocated to the preoperative online intervention group (test group) and the non-online intervention group (control group). Two patient interview topic guide questionnaires were utilized to assess the extent and source of patients' understanding of the treatment process after a consultation at the hospital (T1) and prior to the surgery (T2). The preoperative dental anxiety was also assessed using the modified Corah dental anxiety scale (MDAS) at T1 and T2. All patients used the visual analog scale to describe their pain perception and satisfaction with the treatment process immediately after surgery (T3). A correlation analysis was performed to analyze the interrelationship between patient understanding, dental anxiety, pain perception, and satisfaction. At T1, both groups were homogenous in their knowledge of the TSFE procedure and preoperative dental anxiety. At T2, the test group showed a better understanding of the TSFE procedure and lower preoperative dental anxiety than that of T1 and the control group at T2. Pain perception was significantly lower in the test group than in the control group at T3. Patients in the test group expressed significantly greater satisfaction with the treatment process than the control test group. There was a negative correlation between patients' understanding and preoperative dental anxiety. A positive correlation between preoperative dental anxiety and pain perception was found with a significant difference. Patients' satisfaction was positively correlated with understanding and negatively correlated with pain perception. Preoperative online intervention effectively increased patients' understanding of the treatment process. This resulted in decreased preoperative dental anxiety, decreased pain perception, and greater postoperative satisfaction from patients who underwent TSFE. Online medical care can be considered as an auxiliary tool to improve the effect of implant surgery.

The influence of sedation and general anesthesia to patients' psycho-emotional status undergoing wisdom teeth extraction: a pilot clinical trial

Background:Patients usually face negative psycho-emotional status during teeth extraction, therefore sedation and general anesthesia are often selected for wisdom teeth extractions. The aim of this study is to evaluate the difference between sedation and general anesthesia patients' psycho-emotional status and pain, using Universal Scale in Oral Surgery for Psycho-Emotional Rating (USOS), Visual Analogue Scale (VAS) and Modified Corah's Dental Anxiety scale (MDAS).Methods:In the period of 10/21/2019–01/31/2020 a prospective control study was held of adult patients for extraction of four wisdom teeth with sedation or general anesthesia. Patients were evaluated using self-reported questionnaires and physician questionnaire.Results:In total 53 patients were included in study: 43 in the sedation group (SG) and 10 in the general anesthesia group (GAG). Patients' psycho-emotional status was significantly (p&lt; 0.05) more negative in both groups at the day of surgery than before it, but the difference of fear was higher in GAG (p&lt; 0.05). Immediately after surgery GAG (3.80) felt statistically significantly (p&lt; 0.05) more pain than SG (2.60).Conclusion:Sum of USOS, MDAS, dental fear data scores, pulse measurements directly correlated with time,i.e.statistics increased as surgery approached. The pain sensation differences were found only in the assessment immediately after surgery.

Comparison of active versus passive audiovisual distraction tools on children's behaviour, anxiety and pain in paediatric dentistry: a randomised crossover clinical trial.

To determine the effect of active distraction when playing PlayStation® video games, compared to passive distraction when watching a cartoon with audiovisual eyeglasses, on parental perception of patients' anxiety, and children's anxiety, pain, behaviour and heart rate during restorative procedures in paediatric dentistry. Study design: Randomised crossover clinical trial. There were 34 patients in the cartoon film group (passive distraction) and 34 in the Playstation® video game group (active distraction), aged 6-8 years, who required a minimum of 2 visits for restorative treatment. Rimax® iVision 5.0 eyeglasses were used in both groups. Parental perception of patients' anxiety (Modified Corah Dental Anxiety Scale), and children's anxiety (Venham Picture Test), pain (Wong-Baker Faces Scale), behaviour (Frankl Scale) and heart rate were evaluated at each of the treatment visits. Preference for and satisfaction with the audiovisual product were also assessed. There were significant differences in self-reported pain between control (P=0.016) and experimental (P=0.013) visits in both groups, with lower values in the Playstation® video game group. No significant differences were found (P>0.05) in the other variables evaluated with the use of active distraction. A significant increase in heart rate was recorded at each treatment visit (P=0.0001) when the anaesthetic was injected. All the patients wanted to continue watching or playing their chosen cartoon or Playstation® video game during subsequent visits. The use of PlayStation® video games for active audiovisual distraction, compared with passive distraction with a cartoon, improved self-reported pain but did not reduce parents' perception of patients' anxiety, pain, global behaviour, or heart rate. Both distraction methods were accepted by paediatric patients.

Temor hacia el odontólogo en niños menores de 5 años

La ansiedad dental en la edad infantil se relaciona con la salud bucal del adulto. Se realizó un estudio descriptivo, transversal, con enfoque mixto, durante enero a diciembre del año 2016. Se trabajó con la totalidad de la población, conformada por los menores de cinco años de edad, de ambos sexos (20 individuos) que durante el período de estudio acudieron a las consultas de atención estomatológica en el Dispensario Médico-Odontológico de Marcopamba, en la provincia de Bolívar, Ecuador. Mediante consentimiento informado, se obtuvo la aprobación de los padres para que sus hijos participaran en el estudio. Se confeccionó una ficha de recolección de datos, la que permitió explorar la frecuencia de asistencia al Odontólogo, los motivos de consultas y la realización de la técnica de cepillado dental. Para determinar la presencia de ansiedad y miedo dental, se empleó la Escala de Ansiedad Dental de Corah Modificada, la que su validación recoge un índice de confiabilidad de alfa de Cronbach de 0,86 y una validez determinada como aceptable. Predominó la asistencia a consulta odontológica debido a la presencia de dolor dental. La totalidad de la población de estudio refirió no realizar cepillado dental cuatro veces al día. La clasificación clínica de muy ansioso e intranquilo fue mayoritaria entre los individuos participantes, lo que sugiere la necesidad de establecer estrategias de promoción de la salud oral y prevención de enfermedades bucodentales, para reducir factores que producen miedo y temor al odontólogo.

Effect of Verbal and Visual Information on the Level of Anxiety among Dental Implant Patients

To compare the effect of visual information and verbal communication on the level of anxiety among patients undergoing dental implant (DI) therapy. A total of 270 patients who were undergoing DI treatment were recruited for the study. An equal number of patients (n = 90) were randomly allocated into three study groups which were formed on the basis of the mode of delivery. Subjects in group I received verbal information, whereas patients in group II were shown a video of surgery on manikins. Group III subjects were made to watch a video of surgery on a real patient. Before the surgery, anxiety levels were measured for all patients using the modified Corah dental anxiety scale (MDAS). Questionnaires were filled by all patients and were later analyzed. The values of Cronbach's α and the behavioral involvement subscale were 0.89 and 0.91, indicating hemogeneous sample. Patients of group I showed significantly reduced anxiety levels (p < 0.01) followed by groups II and III. Verbal information generated less anxiety than visual information on patients undergoing DI therapy. To assess the best method of information delivery to dental implant patients in which their anxiety will be minimal.

Impact of audiovisual information on anxiety and fear in patients undergoing dental implant treatment.

Few studies have reported the impact of audiovisual implant surgery information on anxiety and fear. To investigate the impact of audiovisual information on anxiety and fear in patients undergoing dental implant treatment. This study included 300 patients due to undergo surgery to place a single implant. An interview topic guide and the Krantz Health Opinion Survey (KHOS) survey were used to assess the information patients already had about treatment and how much information they were seeking. Afterwards were randomized into two groups (n = 150): group 1 (verbal information) and group 2 (audiovisual information). Before surgery, anxiety and fear were assessed using State-Trait Anxiety Inventory (STAI), Modified Corah Dental Anxiety Scale (MDAS), and Dental Fear Scale (DFS) scales. After treatment, all patients described their satisfaction with the information received with a VAS. Before receiving information, both groups were homogenous in their knowledge of the implant procedure (P = .825) and the quantity of information sought (KHOS; P = .080). After receiving information, group 2 patients presented more anxiety and fear than group 1 (STAI-State, STAI-Treat, MDAS, DFS; P < .001). After surgery, both groups were equally satisfied with the information received and the need for additional information (P = .689; P = .199, respectively). Audiovisual information generated greater anxiety and fear than conventional verbal information in patients undergoing implant surgery.

Dental anxiety in the municipal personnnel of Biblián, Ecuador, 2018.

The aim of this study was to determine the degree of dental anxiety in the staff of the Municipality of Biblián, Ecuador. A cross-sectional study was carried out using the modified Corah dental anxiety scale in its Spanish version. A total of 159 employees, 72.3% men and 27.7% women, were included. The most prevalent level of dental anxiety was mild or none (37.1%), followed by moderate anxiety (35.6%), and severe anxiety or phobia (13.8%). The most prevalent degree of anxiety in men was mild or null (28.9%), and in women this was moderate at 8.8%. In relation to age, the group aged 31 to 50 years had the highest prevalence of severe dental anxiety or phobia (9.4%). The staff of the Municipality of Biblián presented a high prevalence of mild or no anxiety.

Parental acceptance of behaviour-management techniques used in paediatric dentistry and its relation to parental dental anxiety and experience

The aim of this study was to examine the acceptance by Greek parents of nine behaviour-management techniques and its association with several possible confounding factors. Following ethical approval, 106 parents whose 3- to 12-year-old children had been receiving treatment in a university postgraduate paediatric dental clinic, and 123 parents of children from a private paediatric dental practice agreed to participate. After being shown a video with nine behaviour-management techniques, parents rated the acceptance of each technique on a 0-10 scale. They were then asked to complete a questionnaire about demographics, their previous dental experience and dental anxiety (modified Corah dental anxiety scale). The best accepted technique was tell-show-do (9.76 ± 0.69), followed by parental presence/absence (PPA) technique (7.83 ± 3.06) and nitrous oxide inhalation sedation (7.09 ± 3.02). The least accepted techniques were passive restraint (4.21 ± 3.84) and general anaesthesia (4.21 ± 4.02). No correlations were found between acceptance of any individual management technique and parental age, gender, income, education, dental experience and dental anxiety or the child's age, gender and dental experience. Parents whose children had been treated at the University clinic had lower income and educational levels, and rated passive restraint, oral sedation and general anaesthesia higher than those from the private practice. When the parents were specifically asked to choose between general anaesthesia over any of the active or passive restraint, hand-over-mouth and voice control techniques, 10% preferred general anaesthesia, and these parents reported statistically significant more negative dental experience but not higher dental anxiety. Statistical significance of differences was explored using the Tukey-Kramer method. There was no correlation between parental dental experience and dental anxiety and the acceptance of any specific behaviour-management technique. However, parents with negative dental experience would prefer general anaesthesia over any of active or passive restraint, hand-over-mouth and voice control techniques. PPA is a highly acceptable technique for Greek parents.

Assessment of the Prevalence of Dental Anxiety among Palestinian Clients Attending Dental Clinics in Bethlehem City: Cross Sectional Study

Objective: To investigate the prevalence of dental anxiety as well as the relationships between socio-demographic data and perceived dental anxiety among Palestinian clients who attend dental clinics in Palestine. Materials and methods: Participants were recruited into the study from July to August, 2013 from several dental clinics. The modified Corah Dental Anxiety Scale (DAS) was used to measure dental anxiety among the study population. Results: One hundred and sixty four respondents returned the questionnaire after they filled it while in the reception area waiting their turn to see the dentists. Findings reveal that more than one third of the participants experienced a severe level of dental anxiety and were anxious mostly about tooth drilling and local anesthetic injection. Females experienced significantly more dental anxiety than males, but the relationships with other socio-demographic data (including education, place of residency, marital status, and visit habits ) were not significant. Conclusion: This study found high prevalence of dental anxiety which may represent special challenges to the dentists to treat individuals with dental fear. Non of the socio-demographic data except gender revealed statistically significant relation with dental anxiety among the study population Further studies are required to investigate the factors that may lead to increased the prevalence of this phenomena among the Palestinian clients.

Assessment of anxiety related to dental treatments among patients attending dental clinics and hospitals in Ranga Reddy District, Andhra Pradesh, India.

To assess the levels of dental anxiety among patients anticipating dental treatments in dental clinics/hospitals of Ranga Reddy district. A cross-sectional study was conducted among a representative sample of 1200 subjects (at least 18 years old) in dental clinics/hospitals which were selected from a list obtained through systematic random sampling. The data were collected using a pre-tested and calibrated questionnaire consisting of the Modified Corah Dental Anxiety Scale (MDAS) to assess anxiety levels. The majority (52.4%) of subjects showed a low level of anxiety. Females (11.44 ± 4.41) were found to have higher mean MDAS scores than males, and the highest mean MDAS scores were found among 18- to 34-year-olds (11.28 ± 4.67) (P < 0.05). Significant differences were found among subjects anticipating different treatments, with higher MDAS scores for extraction (11.25 ± 5.4), followed by examination, root canal treatment, gum surgery, scaling, restoration and others, e.g. orthodontic treatment, restoration with crowns, bridges and dentures (7.79 ± 3.80). The highest mean MDAS scores were found among subjects who were apprehensive due to 'past difficult experience in dental treatments', followed by 'drill' and 'injection', with the lowest scores among subjects indicating 'other reasons' (7.82 ± 3.84). The present data show that anxiety levels are higher in patients who have to undergo extractions than those who must be fitted with dentures. Thus, dental health care providers should pay more attention to patients' anxiety levels associated with different types of treatment.

Self-reported causes for referral to dental treatment under general anaesthesia (DGA): a cross-sectional survey

To determine causes leading to dental care under general anaesthesia (DGA) in public health care reported by the patients or the parents/caregivers. All the patients referred to DGA at the Municipal Health Centre, Oulu, Finland, during 10 months were invited to participate in the present cross-sectional survey. They were sent a questionnaire on indications for referral to DGA, dental fear, possible reasons for it as well as prior treatment of dental fear. For measuring overall dental fear, the modified Corah dental anxiety scale (MCDAS) and visual analogue scale (VAS) forms were also included in the questionnaire. The most common self-reported indication for referral to DGA was dental fear (63.9%). For children and adolescents (<18 years), need for extensive care was the second most common reported cause. The great majority of the respondents reported having dental fear (90.8%). Dental fear was more common among females than males, but the difference between the genders was not statistically significant. The most common cause for dental fear was earlier negative experiences in dental care (51.9%). The mean MCDAS score was 19.0 (SD 5.7; 5-25) indicating severe dental anxiety. An increasing trend towards older age groups could be seen in VAS scores reporting fear of pain, needles, scaling, scolding by the dentist, extractions, as well as endodontic treatment. Dental fear had been taken into consideration in dental treatment preceding DGA. Dental fear is the most common self-reported indication for referral to DGA and should be taken into consideration.

Assessment of general pre and postoperative anxiety in patients undergoing tooth extraction: a prospective study

Our aim was to analyse the amount of anxiety and fear felt before, immediately after, and one week after, dental extraction. We studied 70 patients (35 men and 35 women (mean (SD) age 43 (±10) years), who were listed for dental extraction under local anaesthesia in a private clinic that specialised in oral surgery. Patients were evaluated on 3 consecutive occasions: immediately preoperatively, immediately postoperatively, and 7 days later. Each patient's anxiety was measured using Spielberger's State-Trait Anxiety Inventory (Spanish version), the Modified Corah Dental Anxiety Scale (MDAS) and the Dental Fear Survey. There were significant differences in the STAI-Trait scale between before and 7 days after extraction (p=0.04), and in the MDAS between before and immediately after extraction (p=0.02), and between immediately after and 7 days after extraction (p=<0.001). The DFS also differed between before and immediately after extraction (p=0.002), and between immediately and 7 days after extraction (p<0.001). Dental anxiety immediately after tooth extraction may be influenced by operative techniques (type of anaesthesia, duration of operation, or position of tooth extracted), but anxiety at 7 days after extraction is not.

Anxiety due to Dental Treatment and Procedures among University Students and Its Correlation with Their Gender and Field of Study

Aim of Study. To investigate dental anxiety levels among university students and its relation with their specialty and gender. Materials and Methods. 850 undergraduate university students were recruited into the study. The Modified Corah Dental Anxiety Scale (MDAS) was used to measure the levels of their dental anxiety. 700 questionnaires were returned, 390 females and 310 males (response rate of 0.92% among females, 0.73% among males). The MDAS score ranged from 5 to 25. Patients were considered to suffer from high dental anxiety if they scored 13 to 20 points. Statistical analysis significance was set at P ≤ 0.05. Results. Seven hundred students participated in this study including 13% of medical students, 10% of dental students, 58% of arts students, and 18% of computer science students. Medical and dental students were less anxious than arts and computer science students (P < 0.05). Local anesthesia injection was the most fearful dental procedure (P < 0.05). Females were more anxious than males (P < 0.05). Conclusion. Male students were less anxious than female students. Students from medical background faculties were less anxious than students from nonmedical faculties. Lack of adequate dental health education may result in a higher level of dental anxiety among nonmedical students in Saudi Arabia.

Dental anxiety among university students and its correlation with their field of study

Objective:This study was designed to investigate the subjective ratings of dental anxiety levels among university students enrolled at Jordan University of Science and Technology. In addition, the present study aimed to explore the sources of dental anxiety and the impact of gender on the perceived dental anxiety and the correlation between field of study and dental anxiety level.Material and Methods:The Modified Corah Dental Anxiety Scale was used to measure dental anxiety among the study population. Six hundred subjects were recruited into the study from Jordanian undergraduate students from the faculties of Medicine, Engineering, and Dentistry.Results:Five hundred and thirty five complete questionnaires were returned, which accounts for a response rate of 89.2%. The totals of the mean anxiety scores were the following: Medical students, 13.58%; Engineering students, 13.27% and dental students, 11.22%. About 32% of the study population has scored 15 or more. Dental students had the lowest percentage of those who scored 15 or more. Surprisingly, the medical students were responsible for the highest percentage of those who scored 15 or above. Although women demonstrated statistically higher total dental anxiety scores than men (p= 0.03), the difference between both genders was small and could be clinically insignificant. The students were anxious mostly about tooth drilling and local anesthetic injection.Conclusion:Lack of adequate dental health education may result in a high level of dental anxiety among non-dental university students in Jordan. Further studies are required to identify the correlates of dental anxiety among university students.
