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

IS THERE A CORRELATION BETWEEN OBJECTIVE AND SUBJECTIVE METHODS TO ASSESS DENTAL ANXIETY? A SYSTEMATIC REVIEW AND META-ANALYSIS

OBJECTIVE

To assess the evidence about the correlation between objective and subjective methods for evaluating dental anxiety.

METHODS

Eligibility criteria were defined as follows: Patients (P): individuals in the dental care context; Index test (I): subjective methods; Reference test (R): objective methods; Outcome (O): correlation between methods to dental anxiety evaluation. Searches were conducted in 7 databases and grey literature up to November 2023, without language or date restrictions. The QUADAS-2 tool was employed to evaluate Risk of bias. A random-effects meta-analysis was performed to calculate pooled correlation coefficients between methods on the basis of the objective method analyzed. The GRADE approach was utilized to assess evidence certainty.

RESULTS

A total of 29 studies, with 1891 participants aged 3 to 82 years, were included, with 22 studies participating in the meta-analysis. The Risk of bias was mostly "unclear" due to inadequate methodology detail. Weak correlations were observed between subjective methods and heart rate (r 0.15 [0.08, 0.21], P < .001, I2 = 56%) and alpha-amylase (r 0.25 [0.11, 0.38], P < .001, I2 = 43%. Subjective methods showed a moderate correlation with cortisol analysis (r 0.40 [0.33, 0.47] P < .001, I2 = 72%). No other objective method displayed a significant correlation with subjective methods. The certainty of evidence was very low.

CONCLUSION

The findings can suggest a correlation between the following subjective and objective methods: ACDAS, DAS, MCDAS, MDAS and Cortisol; CFSS-DS, DAS, MCDAS, MDAS and Alpha-amylase; and DAS, DAS-R, MDAS, S-DAI, Venham Picture Anxiety, Venham Picture Test and Heart rate. Nonetheless, these results lack conclusiveness due to their very low certainty of evidence.

Psychological, Sleep, and Heart Rate Variability Responses During Early- and Middle-Term Acclimatization of "Living High-Training Low and High"

Pirlot, Thibaud, Thibaud Mihailovic, Philippe Gimenez, Grégoire P Millet, Franck Brocherie, Eric Fruchart, Gilles Ravier, Romain Baron, Sandrine Bouzigon, Emmanuel Guirronnet, Alain Brunet, and Alain Groslambert. Psychological, sleep, and heart rate variability responses during early- and middle-term acclimatization of "Living High-Training Low and High". High Alt Med Biol. 00:00-00, 2025. Background: This study investigated the relationships between psychological responses, sleep, and heart rate variability (HRV) before and during a "living high-training low and high" (LHTLH) camp. Methods: Ten elite female cyclists (mean ± SD, age = 17.3 ± 1.2 years, VO2max = 54.9 ± 6.9 ml·min/kg) were monitored for 19 days divided into three periods: (1) normoxia (5 days preceding LHTLH), (2) early acclimatization period (days 1-4 of LHTLH), and (3) middle acclimatization period (days 5-14 of LHTLH) in normobaric hypoxic chambers set at a simulated altitude of 2,800 m. During the intervention, their training load (TL), sleep disturbance, psychological (stress, activation state, and perseverance) and physiological responses (sleep architecture, nocturnal peripheral oxygen saturation [SpO2], and HRV) were monitored. Results: In normoxia, no significant correlations were observed between TL and any psychological and physiological responses. However, in the early acclimatization period, significant correlations were found between sleep disturbance and SpO2 (r = -0.83, p < 0.005) and between achieving objectives and HRV (r = -0.91, p < 0.005). In the middle acclimatization period, significant correlations were found between the feeling during training and SpO2 (r = 0.83; p < 0.005). Conclusion: This indicates that LHTLH exacerbates the psychophysiological interactions during the early acclimatization period that disappear during the middle acclimatization period while others appear.

Effectiveness of a dental simulation game on reducing pain and anxiety during primary molars pulpotomy compared with tell-show-do technique in pediatric patients: a randomized clinical trial

BACKGROUND

Dental simulation games are virtual educational games that help children get familiar with different dental procedures. This study aimed to evaluate the pretreatment exposure to the "Baby Panda Dental Care" game in reducing pain and anxiety in comparison with the tell-show-do (TSD) technique during primary molars pulpotomy for patients aged 6-10 years.

MATERIALS AND METHODS

It was a triple-blinded, two-arm, parallel-group, randomized, active-controlled trial. It was done on 60 patients, who were randomly divided into two groups: the control group, TSD technique (n = 30), and the experimental group, "Baby Panda Dental" Care (n = 30). For the TSD technique, children were provided with a verbal explanation followed by a demonstration of the dental treatment in a non-threatening way. The "do" phase is then initiated during performing treatment. For the "Baby Panda dental care" game, children were asked to play for 5 min before treatment, selecting root canal therapy procedures. Pulse rate and RMS pictorial scale were recorded at four time points: (1) at the baseline (t0). (2) After conditioning the child (t1). (3) During treatment (t2). (4) After finishing the treatment (t3). Face, Legs, Activity, Cry, Consolability (FLACC) behavioral pain scale was recorded during treatment (t2).

RESULTS

The pulse rate is higher in the control group at t1 (p = 0.012) and t2 (p = 0.015). There was a statistically significant difference in the mean RMS pictorial scale score at t1 (p < 0.001), t2 (p = 0.006), and t3 (p < 0.001), a statistically significant difference was noticed in FLACC behavioral pain assessment between the two groups (p = 0.033).

CONCLUSIONS

The mobile dental game showed better results than the TSD technique, but neither technique did not reduce anxiety and pain effectively during dental treatment.

Hypnosis and nitrous oxide impact on the school aged patients' anxiety and cooperation candidate for tooth extraction: A randomized clinical trial

Background

This randomized clinical trial (RCT) investigated whether hypnosis would lead to favorable outcomes in reducing anxiety, enhancing cooperation, and improving physiological responses in school-aged children undergoing tooth extraction compared to nitrous oxide/oxygen (N2O/O2) and conventional behavior guidance (CBG).

Methods

Sixty-six school-aged children (mean age: 7.87 ± 1.18 years) who needed one posterior primary tooth extraction were included. Children with low-to-moderate anxiety were randomly divided into three groups (n = 22 each): hypnosis, N2O/O2, and CBG. Anxiety levels during and after anesthetic injection and tooth extraction were assessed using the Venham Clinical Anxiety Scale (VCAS) and the Venham Picture Test (VPT). Changes in heart rate (HR) and oxygen saturation (SpO2) were monitored. Children's cooperation levels were measured using the Venham Clinical Cooperation Scale (VCCS).

Results

The VPT scores were significantly higher in the CBG group than in the N2O/O2 and hypnosis groups (p < 0.001). The VCAS scores in the N2O/O2 group were lower than those in the CBG group (p < 0.05) and were comparable to those in the hypnosis group. The VCCS scores were significantly higher in the CBG group than in the N2O/O2 and hypnosis groups (p < 0.05). HR changes in the N2O/O2 group were significantly lower than in the hypnosis and CBG groups (p < 0.05). No significant difference in pain was observed between the groups the day after the intervention.

Conclusion

N2O/O2 inhalation and hypnosis are effective in reducing self-reported and observed anxiety and improving cooperation levels in pediatric patients during dental extraction. Moreover, the frequency of reported pain was lower in the hypnosis group compared to the other groups.

The relationship between temperament and dental fear and anxiety: a systematic review

OBJECTIVE

To investigate the relationship between temperament traits and dental fear and anxiety (DFA) in children and adolescents by the means of a systematic review (PROSPERO #CRD42020207578).

METHODS

The PEO (Population, Exposure, and Outcome) strategy was followed using children and adolescents as the population, temperament as the exposure, and DFA as the outcome. A systematic search for observational studies (cross-sectional, case-control, and cohort) without restrictions on year or language of publication was performed in seven databases (PubMed, Web of Science, Scopus, Lilacs, Embase, Cochrane, and PsycINFO) in September 2021. Grey literature search was performed in OpenGrey, Google Scholar, and in the reference list of included studies. Study selection, data extraction, and risk of bias assessment were carried out independently by two reviewers. The Fowkes and Fulton Critical Assessment Guideline was used to assess methodological quality of each study included. The GRADE approach was performed to determine the certainty of evidence of relationship between temperament traits.

RESULTS

This study recovered 1362 articles, of which 12 were included. Despite the high heterogeneity of methodological aspects, qualitative synthesis by subgroups showed a positive association/correlation between emotionality, neuroticism, and shyness with DFA in children and adolescents. Different subgroups analysis showed similar results. Eight studies were classified as having low methodological quality.

CONCLUSION

The main shortcoming of the included studies is the high risk of bias and a very low certainty of evidence. Within its limitations, children and adolescents with a temperament-like emotionality/neuroticism and shyness are more likely to present higher DFA.

Association of Age and Temperamental Traits with Children's Behaviour during Dental Treatment

During paediatric dental treatment, cooperation by children is essential, and temperament can determine their behaviour style. This study aimed to associate temperamental traits and age with behaviour during paediatric dental treatment. This was an observational and cross-sectional study of patients aged 3-10 years. To determine the temperamental traits, an Emotionality Activity and Sociability Temperament Survey (EAS) was performed with the children's parents. The type of behaviour was determined with Frankl's criteria. The total scores for temperamental traits, means, and standard deviations were obtained. The chi-squared test, one-way ANOVA and Student's t-test were applied. A total of 140 patients, who were 5 ± 2.1 years old, participated in the study. Age was determinant for negative behaviour, with a greater frequency in children ≤5 years old (p < 0.05), and a significant negative correlation between age and behaviour (rho = -0.245, p = 0.001). Patients with higher emotionality and activity presented negative and definitely negative behaviours more frequently (p < 0.01). The values for sociability and shyness were similar for positive or negative behaviours. In conclusion, the temperamental traits of emotionality and activity were more frequent in children with disruptive behaviours; therefore, conducting a survey on temperamental traits can be useful for planning behavioural approaches in paediatric dentistry.
