Scenting serenity: influence of essential-oil vaporization on dental anxiety - a cluster-randomized, controlled, single-blinded study (AROMA_dent)

Dental fear and anxiety (DFA) is known as an immense challenge in oral healthcare, which can result in compromised oral health, pain, and uncomfortable treatment. The objective of this study was to analyze the effect of essential-oil vaporization on acute anxiety of patients in dental practices. Four dental practices used five weekly cycles of vaporization with each scent: Orange (Citrus sinensis), Swiss Pine (Pinus cembra), Good Mood (blended essential oils: Citrus sinensis, Citrus aurantifolia, Citrus limon, Osmanthus fragrance (5%)), Forest Walk (blended essential oils: Abies grandis, Pinus cembra, Myrtus communis c. t. 1,8-cineol, Abies alba, Citrus paradisi, Abies sibirica, Pseudotsuga menziesii, Vetiveria zizanoides), and water. Acute anxiety was the primary outcome (state-trait-anxiety inventory (STAI-S)). Secondary outcomes were trait anxiety (STAI-T), dental anxiety (Kleinknecht dental fear survey), and pain perception in treatment (numeric rating scale). Across all patients (n = 486), STAI-S was slightly higher in the control group (40.7 ± 11.6) than in the intervention groups (38.4 ± 10.5). Post-hoc analyses revealed that the effect is only robust for the subgroup of female patients (n = 296, p = 0.044). We also conducted a post-hoc additional analysis on a subpopulation with an increased level of STAI-T ≥ 42 (n = 131 patients). For this group the difference in acute anxiety between the control group (51.1 ± 11.9, n = 30) vs. the intervention groups (46.8 ± 9.6, n = 118) was significant (T = 4.39, p = 0.0379). The results of the study indicate a promising potential of essential-oil vaporization to alleviate dental anxiety, particularly in the subgroups of patients with a high level of trait anxiety, and particularly in female patients. The calming effects of the essential-oil vaporization were also highlighted by the anecdotical statements of the dental-practice staff. The anxiety-reducing role of essential-oil vaporization alone and as one part of combined techniques to counter DFA should be further explored using multi-perspective methodological approaches in research.

Adapting a Dental Anxiety Measure to Encourage Empathy

Introduction

The aim of this study was to improve upon the Modified Dental Anxiety Scale (MDAS) by developing the empathy-based International-Modified Dental Anxiety Scale (I-MDAS). This new measure was then utilized to compare the dental anxiety of patients cross-culturally. Methodology. This study was a descriptive cross-sectional study adapting the MDAS into the I-MDAS by adding the International scale. The study surveyed 465 participants from a dental clinic, SurveySwap, and distributed flyers. Data was collected through Qualtrics through the self-administered I-MDAS and analyzed through the SPSS computer software version 28. Participants were categorized into two subgroups where 41.3% received dental care only within the United States and are termed the domestic population, and 58.7% received dental care outside of the United States and are labeled the nondomestic population. Information about demographics, past negative dental experiences, and current dental anxiety was collected. The conducted analyses utilized an independent sample t-test to compare the subgroups' anxiety levels, a bivariate correlation to find the Pearson correlation, a Cronbach's coefficient α, and a one way ANOVA test to compare the genders' I-MDAS scores.

Results

There was no significant difference in dental anxiety levels between the domestic population (M = 12.73, SD = 5.13) and the nondomestic population (M = 12.76, SD = 5.06); t (463) = -0.58, p = 0.95). The I-MDAS shows evidence of validity and reliability. There was a significant and positive relationship between the International scale items and the MDAS scale items (r (463) = 0.60, p < 0.001), indicating the criterion validity of the I-MDAS. Content validity was strengthened by expanding the inquired topics in the new measure. The Cronbach's α value of 0.85 shows that the I-MDAS is reliable for clinical applications.

Conclusions

The I-MDAS improves upon the MDAS by providing dentists with a tool for encouraging empathy. Dental clinicians across nations can use the I-MDAS to combat the vicious cycle of dental anxiety.

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.

Relationship between subjective and objective measures of anticipatory anxiety prior to extraction procedures in 8- to 12-year-old children

Background

This study assessed anticipatory dental anxiety levels among 8- to 12-year-old children based on subjective and physiological measures and their correlation. The variations in anxiety based on sex, age, temperament, and academic performance were evaluated.

Methods

An observational study was conducted in 60 children recruited from the waiting room over a 6-month period. The operator recorded subjective anxiety in the children using a novel visual facial anxiety scale. The operator also noted the demographic details and child's temperament using the nine dimensions of the Thomas and Chess criteria, and graded children as "easy," "slow to warm-up," and "difficult." The academic performance of the children was graded (parental ratings) on a five-point Likert scale. Physiological variables (heartrate [HR], oxygen saturation[SpO₂], and blood pressure [BP]) were recorded by another evaluator. The correlation between anxiety levels and physiological variables was also assessed. The effects of age, sex, temperament, and academic performance on anxiety were evaluated.

Results

The study included 60 children aged 8-12 years, including 36 boys and 24 girls. Seventy percent of children had mild to moderate levels of pre-extraction anxiety, while 30% of children demonstrated high anxiety. A significant positive correlation was noted between anxiety levels and HR (r_s = 0.477, P < 0.001^*) and systolic BP (r_s = 0.294, P < 0.05), while a significant but inverse correlation was observed with SpO₂ (r_s = -0.40, P < 0.05). Anxiety did not influence diastolic BP. Children with difficult temperament and poor academic performance had significantly higher anxiety.

Conclusion

A high percentage (70%) of children aged 8-12 years had mild to moderate anxiety prior to the extraction procedure. Increased HR, systolic BP, and reduced SpO₂ were significantly associated with high levels of anticipatory dental anxiety. Pre-extraction anxiety was significantly related to the temperament and scholastic performance.

The impact of dental treatment and age on salivary cortisol and alpha-amylase levels of patients with varying degrees of dental anxiety

Background

The purpose of this study was to assess the salivary cortisol and salivary alpha-amylase levels in children aged between 6 and 9 years, 3 months and 1 year after the successful completion of dental treatment through either pharmacological or non-pharmacological behavior management techniques.

Methods

A total of 1567 patients aged between 6 and 9 years who had completed dental treatment were screened. A total of 703 patients who were caries free at the end of 3 months were classified based on Frankl behavior score and administered the Arabic version of the Children’s Fear Survey Schedule- Dental Subscale (CFSS-DS) and accordingly allocated to one of three groups; (Phobic Patients, Anxious Patients, Control Group). A total of 183 patients met the inclusion criteria and were followed up for 1 year. A total of 151 patients completed the study. Patients’ heart rate on recall, salivary cortisol and salivary amylase were compared between the groups.

Results

The results of the study showed that amylase and cortisol levels had a significant association with the level of dental fear. The phobic patients had the highest levels of salivary amylase and salivary cortisol levels with no significant associations observed with either heart rate or extent of dental treatment. Control and anxious patients had significantly lower amylase levels when compared to phobic patients. There was no significant difference between the salivary cortisol levels of anxious and phobic patients. These findings were replicated on 1-year recall.

Conclusions

Within the limitations of this study we can conclude that salivary amylase is an indicator of of acute stress that can differentiate between anxiety and dental fear; while salivary cortisol appears to be a marker of long-term stress that lacks the sensitivity to differentiate between the two.

The long-term effect of previous dental treatment under general anaesthesia on children's dental fear and anxiety

BACKGROUND

Dental treatment under general anaesthesia (DGA) is deemed to contribute to children's dental fear and anxiety (DFA), both in the short term and long term.

OBJECTIVE

To compare DFA between children who had previous DGA and those who did not.

METHODS

A cross-sectional survey included 5- to 12-year-old children who had undergone DGA (n = 43) and a control group who had not (n = 55). Questionnaires were completed by parents regarding sociodemographic and dental profiles. Children's Fear Survey Schedule-Dental Subscale (CFSS-DS) and the Modified Child Dental Anxiety Scale (faces) (MCDASf) were completed by children.

RESULTS

The mean age of the control group and the DGA group was 9.5 ± 1.7 and 8.8 ± 1.5 years old, respectively (P > 0.05). The time passed since DGA was experienced ranged between 1.2 and 6.9 years ago (mean: 4.2 ± 1.1 years). The mean CFSS-DS and MCDASf scores for the DGA group (34.3 and 20.4, respectively) were significantly greater when compared to the control group (23.6 and 12.7, respectively) (P < 0.001).

CONCLUSION

Children who experienced DGA are a high-risk group for DFA several years after the procedure. The DGA status could be used for identifying anxious children to promote better behaviour management.

Progressive muscle relaxation therapy to relieve dental anxiety: a randomized controlled trial

Dental anxiety causes patients to refuse or delay treatment, which may exacerbate oral diseases. The aim of the current randomized controlled trial was to determine whether progressive muscle relaxation therapy could relieve dental anxiety. The trial included 68 periodontal patients with dental anxiety scores of ≥13 who were randomly assigned to either an intervention group or a control group (n = 34 per group). The intervention group was administered progressive muscle relaxation therapy for 20 min and oral health education for 15 min before periodontal treatment once per week for 4 wk. The control group was provided with oral health education only, for the same duration. Changes in dental anxiety, depression symptoms, blood pressure, heart rate, and salivary cortisol were evaluated 4 wk and 3 months after the intervention. The intervention group exhibited statistically significantly greater reductions in dental anxiety scores than did the control group at the 4-wk (-3.82 vs. -0.89) and 3-month (-4.22 vs. -0.28) assessments. They also exhibited significantly greater reductions in depression symptoms, systolic and diastolic blood pressure, pulse rate, and salivary cortisol levels at both time-points. Progressive muscle relaxation therapy relieves tension and anxiety in dental patients.

Development and evaluation of the Jönköping Dental Fear Coping Model: a health professional perspective

OBJECTIVE

The purpose of this study was to design a structured treatment model focusing on all levels of adult's dental fear, the Jönköping Dental Fear Coping Model (DFCM). The aim was to study the DFCM from a dental health professional perspective.

MATERIAL AND METHODS

The DFCM was studied by means of quantitative and qualitative analyses. Nine dental clinics participated in Period I (pre-intervention/standard care), and 133 dental health professionals (dentists, dental hygienists, dental assistants) and 3088 patients were included. After completion of Period I, four of the clinics were randomized to Period II (intervention), beginning with the professionals undergoing DFCM training. Following that, 51 dental health professionals treated 1417 patients according to the DFCM. The other five clinics served as controls.

RESULTS

Half or more of the dental health professionals assessed the model as better than standard care, regarding anamnesis and diagnostics, communication and contact, and understanding of patients and dental fear. The dental health professionals reported higher tension in their fearful patients in Period II compared with Period I, possibly due to their increased awareness of dental fear.

CONCLUSIONS

The qualitative data suggest that dental health professionals find the DFCM beneficial in routine dental care. The model promotes a holistic approach to the treatment of adult patients. However, stress among the professionals was not reduced when measured, neither quantitatively nor qualitatively. It is important to evaluate the model in further studies to make it possible to draw generalizable conclusions.

The influence of mothers' oral health behaviour and perception thereof on the dental health of their children

Objective

The study aims to investigate how mothers' oral health behaviour and perception thereof influence the dental health in their children.

Methods

A total of 556 Vietnamese mother-child pairs participated in the current study. Mothers self-reported their oral status and oral health behaviour and perception. Dental caries of the children were examined using the index of decayed, missing, and filled teeth. The Dental Anxiety Scale instrument was used to assess the dental anxiety level in mothers and children.

Results

Among mothers, 41.3% had gingival bleeding, 40% perceived their dentition and gingival status to be at a good level, 68% brushed their teeth more than twice a day, and 17% had never visited a dentist. Mothers' oral health behaviour and their perception thereof were positively correlated with their frequency of dental visits (r = (0.105-0.221), p < 0.001) and negatively correlated with dental anxiety (r = (- 0.149- - 0.105), p < 0.05).Caries-free children were positively correlated with mothers having more than 20 teeth (r = 0.085, p < 0.05). Positive correlations between mothers and children were found in terms of frequency of fresh fruits consumption (r = 0.090, p < 0.05), drinking sweet beverages (r = 0.072, p < 0.05), and dental anxiety (r = 0.183, p < 0.001).

Conclusions

Maternal oral health was significantly associated with dental health of their children. Not only did maternal dental anxiety influence oral health of mothers but it was also a concomitant factor in the development of children's dental anxiety. The education programme on mothers' oral health-related knowledge can be a target for improvement of the oral health of mothers and children.

Are dental students ready for supercomplex dental practice?

Contemporary dental practice requires practitioners who are able to draw upon varying interconnected knowledge and skills, in order to make judgments and take action when faced with multiple, often contradictory, ways of interpreting a situation. However, the curricula that prepare students for dental practice are traditionally based on the theoretical knowledge and technical skills to be gained by students. This is despite evidence in the dental literature of a collective desire for graduates to have more range and depth in their repertoire. Examination of contemporary dental practice through the lens of supercomplexity (Higher Education, 40, 409 and 2000) provides contextual understanding and a platform to explore the types of learning and curriculum approaches that can best prepare students for professional practice. From the insights offered by examples from other professional fields, we, as dental educators, can begin to conceptualise learning dentistry as much more than competency frameworks or descriptions of what students need to know and be able to do. Rather, to equip graduates for contemporary dental practice, the dental curriculum needs to become a vehicle for students to develop personally and professionally as well as teaching the theoretical and technical aspects of dentistry.

Anxiolytics, Sedatives, and Hypnotics Prescribed by Dentists in Brazil in 2010

Objective

To describe dental prescriptions for anxiolytics, sedatives, and hypnotics for Brazilian outpatients in 2010.

Methods

A cross-sectional study was conducted using data on the use of anxiolytics, sedatives, and hypnotics from the Brazilian Health Surveillance Agency, Brazil, 2010. For each prescription, prescribed drugs and the prescribed amount were identified. Prescribed medications were classified according to Anatomical Therapeutic Chemical code. We calculated the number of Defined Daily Doses (DDD) for anxiolytics, sedatives, and hypnotics by code, their mean DDD, and DDD per inhabitant per year.

Results

There were 16,436 prescriptions dispensed, including anxiolytics, sedatives, and hypnotics. These prescriptions corresponded to 3,555,780.50 mg, distributed as 2,286,200.50 mg (64.30%) of anxiolytics and 1,269,580.00 mg (35.70%) of sedatives and hypnotics. This amount allowed treating approximately 474,106 individuals (number of DDD). The anxiolytics most frequently dispensed were bromazepam (25.30%), alprazolam (19.19%), and diazepam (15.60%). Sedatives and hypnotics mostly prescribed were zolpidem (9.55%), midazolam (6.99%), and flunitrazepam (2.14%). The per capita rates (100,000 inhabitants) of anxiolytics and sedatives/hypnotics were 6.83 and 1.78, respectively.

Conclusions

Benzodiazepines and derivatives were the most frequently prescribed drugs. There was a low rate of dental prescriptions for anxiolytics, sedatives, and hypnotics, although excessive doses were concentrated in the same prescription.
