The vicious cycle of dental fear at age 31 in a birth cohort in Southern Brazil

Pathways to dental fear from childhood to adolescence: A 10-year cohort study

BACKGROUND

Dental fear affects children's oral health; there is, however, no evidence regarding the pathways linking possible predictors for its occurrence.

AIM

This study aimed at exploring the direct and indirect effects of sociodemographic, clinical, behavioural and psychosocial factors on the development of dental fear in schoolchildren over time.

DESIGN

This is a prospective cohort study, with 10 years of follow-up. The first assessment started in 2010 (T1) with a sample of 639 children aged 1-5 years from Southern Brazil. For this study, the follow-up (T2) of these individuals was performed in 2020. Dental fear was assessed at T2 using the Brazilian version of the Children's Fear Survey Schedule-Dental Subscale (CFSS-DS). Socio-economic, demographic, psychosocial and oral health measures were collected in both assessments. A structural equation model was performed to assess the direct and indirect pathways among variables at T1 and T2 to predict the CFSS-DS scores at T2.

RESULTS

Of the 639 children, 429 were re-evaluated at T2. Higher levels of untreated dental caries, younger individuals, dental visits for nonroutine reasons and low sense of coherence at T2 directly impacted dental fear at T2. Considering the indirect effects, the presence of dental caries and low household income at T1 indirectly impacted higher levels of dental fear over 10 years via dental caries at follow-up.

CONCLUSION

Our findings suggest that socio-economic, demographic, clinical, psychosocial and behavioural conditions can influence dental fear from childhood to adolescence.

Impact of the use of dental services on dental pain according to adolescents' skin colour: a 10-year cohort

OBJECTIVE

Evaluate the association of the interaction between the use of dental services and the skin colour on the occurrence of dental pain over time.

MATERIAL AND METHODS

This study is a cohort with 10 years of follow-up, started in 2010 with a sample of 639 preschool children (1-5 years old). The use of dental services, race and the presence of dental pain were self-reported by the individuals according to predefined criteria. Multilevel logistic regression analysis was performed to assess the interaction between skin colour and use of dental services in the occurrence of dental pain over time.

RESULTS

About 449 and 429 were reassessed in 2017 and 2020, respectively. The occurrence of dental pain across the cohort was 60.7%. Caucasian individuals who used dental services throughout the cohort had a 51% lower chance of having a dental pain than those who used dental services but were non-white (OR 0.49; 95% IC 0.27-0.90).

CONCLUSION

There was a racial inequity in the occurrence of dental pain among individuals who managed to make use of dental services throughout the follow-ups.

CLINICAL RELEVANCE

The differences found should serve as a warning to the way how individuals with different characteristics are treated and must be used to combat this inequity. Individuals should receive resolute and personalized treatments according to their clinical condition and not according to their socioeconomic characteristics.

The Relationship between Dental Fear and Anxiety, General Anxiety/Fear, Sensory Over-Responsivity, and Oral Health Behaviors and Outcomes: A Conceptual Model

Dental fear and anxiety (DFA) is common across the lifespan and represents a barrier to proper oral health behaviors and outcomes. The aim of this study is to present a conceptual model of the relationships between DFA, general anxiety/fear, sensory over-responsivity (SOR), and/or oral health behaviors and outcomes. Two rounds of literature searches were performed using the PubMed database. Included articles examined DFA, general anxiety/fear, SOR, catastrophizing, and/or oral health behaviors and outcomes in typically developing populations across the lifespan. The relationships between the constructs were recorded and organized into a conceptual model. A total of 188 articles were included. The results provided supporting evidence for relationships between DFA and all other constructs included in the model (general anxiety/fear, SOR, poor oral health, irregular dental attendance, dental behavior management problems [DBMP], and need for treatment with pharmacological methods). Additionally, SOR was associated with general anxiety/fear and DBMP; general anxiety/fear was linked to poor oral health, irregular attendance, and DBMP. This model provides a comprehensive view of the relationships between person factors (e.g., general anxiety/fear, SOR, and DFA) and oral health behaviors and outcomes. This is valuable in order to highlight connections between constructs that may be targeted in the development of new interventions to improve oral health behaviors and outcomes as well as the experience of DFA.

Assessment of Dental Anxiety and Hemodynamic Changes during Different Dental Procedures: A Report from Eastern Saudi Arabia

OBJECTIVES

 This study aimed to investigate hemodynamic changes in healthy adult patients during different dental procedures and evaluate whether these changes were associated with patients' dental anxiety.

MATERIALS AND METHODS

 A convenience sample of 119 patients of both genders undergoing routine dental care participated in the study. Participants responded to the Arabic version of the modified dental anxiety scale (MDAS) and a self-structured questionnaire. Each patient had their blood pressure, heart rate, and oxygen saturation measured at three points: before, during, and after the dental procedure using an electronic sphygmomanometer. MDAS scores were categorized into no anxiety, mild, moderate or severe anxiety, while readings of heart rate and blood pressure were categorized into no change, increased or decreased and either "no change" or "increased" for oxygen saturation. Chi-square test was used to investigate the association between the study variables and a p value of < 0.05 was considered statistically significant. SPSS version 20 was used in the analysis.

RESULTS

 Mean ( ± standard deviation [SD]) of MDAS was 11.12 ( ±  3.9) an indicative of moderate dental anxiety. No changes in blood pressure, heart rate, or in oxygen saturation were observed on 39.5%, 54.6% and 97.5% among the study participants, respectively. Half of the participants avoided dental care, with dental anxiety being the main reason for that (26.1%). Pattern of dental visits was significantly associated with MDAS scores (p = 0.042). There were significant changes in blood pressure (p = 0.0003), heart rate (p = 0.01) but not in oxygen saturation (p = 0.33). Changes in blood pressure, heart rate, and oxygen saturation were not associated with dental anxiety p = 0.15, 0.10, and 0.99, respectively.

CONCLUSION

 The results of this study indicate that the type of dental procedure may cause dental anxiety and cause hemodynamic changes. Therefore, close monitoring of patients with dental anxiety during the treatment is advised.

Patients' Perception of Recovery after Dental Implant Placement

Background and Objectives: The success rates of surgical dental implant insertions are high. However, knowledge of patients’ recovery is still lacking. “Health-related quality of life” (HRQOL) questionnaires are gaining popularity in all fields of medicine. The present survey assessed the perception of recovery after the surgical placement of dental implants. Materials and Methods: Forty individuals (26 women and 14 men; mean age, 55 ± 12 years) filled a questionnaire evaluating patients’ perception of recovery for 7 consecutive days post-surgery. Confounding factors included age, gender, oral habits, smoking, bruxism, bone quality (tactile evaluation) and quantity, implant location, number of implants, implant type, length and diameter, one-stage vs. two-stage, and the need for bone grafting. Results: The most serious difficulties were found in swelling, which became minimal after 5 days, followed by eating everyday food, ability to enjoy everyday food, maximal pain and average pain (3 days); analgesics consumption (2.5 days); limitations in daily routine, mouth opening, and speech (2 days); swallowing and sleep (1.5 days); and, within 1 day, all other measures attained minimal levels. Gender, and implant location (anterior vs. posterior) were significant predictor variables exerting their different characteristic delayed recoveries. Conclusions: (1) Patients should expect, in general, recovery within 4 days after dental implant placement; (2) women will experience a delayed recovery, (3) implants placed in the intercanine area will result in postoperative eating difficulties for nearly one week, and (4) the number of implants placed during the same appointment has no effect on post treatment recovery.

Clinical and self-reported oral conditions and quality of life in the 1982 Pelotas birth cohort

AIM

To investigate and compare the effects of clinical and self-perceived oral conditions on oral health-related quality of life (OHRQoL) among young adults.

MATERIALS AND METHODS

Adults enrolled in the 1982 Pelotas birth cohort were included in this study. OHRQoL was assessed by the Oral Health Impact Profile-14 (OHIP-14) instrument. Clinical parameters such as dental caries, periodontitis, aesthetics, and occlusal characteristics, and tongue coating were collected through clinical evaluation, while dental anxiety and halitosis were self-reported. Direct and indirect effects of clinical and self-perceived oral conditions on OHRQoL were assessed using structural equation modelling.

RESULTS

Five-hundred and thirty-nine individuals participated in this study. Dental caries (β = 0.12) and periodontitis (β = 0.11) were directly and indirectly (via halitosis, β = 0.05 for periodontitis only) associated with greater OHIP-14 scores, while the other clinical conditions did not influence the OHIP-14 scores. Dental anxiety and halitosis were also associated with higher OHIP-14 scores (β = 0.31 and β = 0.27, respectively).

CONCLUSIONS

This study found a positive association between clinically diagnosed and self-reported oral conditions and OHRQoL; however, the self-reported conditions had a higher impact on OHRQoL.
