Creating and Validating a Questionnaire for Assessing Dentists' Self-Perception on Oral Healthcare Management-A Pilot Study

BACKGROUND AND OBJECTIVES

Questionnaires designed to test knowledge and self-perception can be valuable tools for diagnosing a dentist's understanding of the management and administration of a practice. The objective of this study was to create and authenticate a questionnaire for assessing dentists' self-perception on oral healthcare management developed from discussions with experts in this field.

MATERIAL AND METHODS

In order to create and verify a questionnaire survey, a cross-sectional, descriptive, and analytical study was carried out. Participants' personal information and 31 statements across four categories made up the final questionnaire form. The answers to the questionnaire were in the form of a Likert scale. After refining the initial version, a total of 36 interviews were conducted at dental offices to verify the validity. For the Exploratory Factor Analysis (EFA), we used the Kaiser-Meyer-Olkin (KMO) index, the Bartlett sphericity test, and also Cronbach alpha coefficient for the validity of the questionnaire.

RESULTS

The accuracy of the instrument was measured by intrarater and interrater reliability. For the EFA, all the communalities exceeded the threshold of 0.05. With a Cronbach's alpha coefficient of 0.898, the questionnaire has sufficient internal consistency.

CONCLUSIONS

The questionnaire demonstrates robust reliability and validity, thereby affirming its suitability for its intended purpose.

Longitudinal Study on Dental Status, Caries Risk Assessment, and Oral Health-Related Quality of Life in 3-6-Year-Old Children Receiving Nitrous Oxide Inhalational Sedation

Introduction Dental caries prevention in early childhood is crucial, necessitating timely assessments by dental professionals and parents. The oral health of children during their early years can significantly impact both the children themselves and their parents' quality of life. This study seeks to assess the changes in oral health-related quality of life after treatment under nitrous oxide sedation in anxious preschool children, for whom treatment otherwise is quite difficult chairside. Aim The aim of this study is to assess the association between dental caries status, risk assessment, and oral health-related quality of life (OHRQoL) in 3-6-year-old children, before and after undergoing treatment under nitrous oxide inhalation sedation. Materials and methods Eighty children were assessed for caries risk and dental status using the caries risk assessment for treatment (CRAFT) tool. Nitrous oxide sedation was employed for dental treatment, and assessments were conducted pre-treatment and post-treatment. Statistical analyses performed were paired t-tests, correlation analyses, and Chi-Square tests. Results The study revealed a mean age of 4.033 ± 0.96, with a balanced gender distribution (47.5% boys, 52.5% girls). Post-treatment, significant negative correlations were observed between OHRQoL and treatment outcomes, emphasizing improved oral health-related quality of life. Associations were found between OHRQoL, pufa index, and caries risk post-treatment. Conclusion The current research suggests that treatment done under nitrous oxide sedation could improve the OHRQoL in preschool children. Integrating risk assessment and OHRQoL enhances understanding, facilitating targeted prevention and treatment strategies. Addressing untreated dental caries is imperative for optimizing the overall well-being of children in this age group.

Early Childhood Oral Health Impact Scale: Psychometric Evaluation in Portuguese Preschoolers

Objective

to contribute to the validation of the Early Childhood Oral Impact Scale (ECOHIS) by studying its psychometric properties when applied to a Portuguese preschool population.

Methods

Cross-sectional study conducted with children aged between three and five-years-old. The non-probabilistic sample included two preschools in the municipality of Lisbon. Children who agreed to participate and whose guardians signed the informed consent were included. Data collection included a questionnaire, administered to the parents, and an intraoral examination of the children. The questionnaire included the Portuguese version of ECOHIS. The intraoral examination included the caries diagnosis according to the World Health Organization criteria. Discriminant validity compared the ECOHIS score between children with and without caries experience (Mann-Whitney U-test). Cohen's d was calculated to estimate the magnitude of the difference. Reliability analysis included Cronbach's α and test-retest. Construct validity was analyzed by the correlation between the ECOHIS score and dmft (Spearman's correlation). A significance level of 5% was used.

Results

The sample included 104 children (mean age 4.1 years). ECOHIS values were significantly different between children with and without caries (p=0.004). The Cohen's d was 0.84. The Cronbach's was 0.78, with no significant increase in value when eliminating any of the items. The test-retest showed significant correlation (r=0.76; p=0.01). There was a significant correlation between the ECOHIS score and caries experience (r=0.28; p=0.004).

Conclusion

The Portuguese version of the ECOHIS showed good psychometric properties, indicating that it is a reliable and valid tool to measure the impact of oral health in preschool children.

Tools Evaluating Child Oral Health-Related Quality of Life

OBJECTIVES

This study aimed to systemically review the tools developed for evaluating oral health-related quality of life (OHRQoL) in preschool children.

METHODS

Two reviewers systematically searched English-language publications within PubMed, Embase, Scopus, and Web of Science. They screened the titles and abstracts and retrieved the full texts of the selected publications. Studies which developed, validated, or culturally adapted an OHRQoL tool used in preschool children were included. They recorded information regarding tool characteristics, item configuration, discriminative validation, the aim of assessment, and the target group.

RESULTS

The study included 59 publications and identified 12 tools for assessing OHRQoL in preschool children. Seven tools were tailored for preschool ages. Most of the scales were generic oral health measures. Dental caries was the most commonly used oral condition for assessing a tool's discriminative validity. Eight tools required parental proxy reports. Three tools were both child-administrated and parent-administrated. One tool was designed to be answered solely by children. Ten tools assessed the oral health-related impact on children, including oral condition-related, functioning, environmental, and emotional/social domains. Four tools included items regarding the impact on both children and family.

CONCLUSIONS

This review identified 12 tools developed for evaluating OHRQoL in preschool children, 7 of which were tailored for preschool age. The 12 tools were validated but incomprehensive due to the subjective and multidimensional nature of the OHRQoL concept. Researchers can choose a suitable tool for their studies by understanding the basic characteristics and item setting of the tools. Researchers can have an overview of the tools developed for evaluating OHRQoL in preschool children. They can use the findings from this review to choose a suitable tool for their studies regarding the OHRQoL in preschool children.

The Early Childhood Oral Health Impact Scale (ECOHIS): psychometric properties and application on preschoolers

Background

The concept of oral health related to quality of life involves the impact that oral health has on an individual's well-being. The Early Childhood Oral Health Impact Scale (ECOHIS) was developed to measure the impact of oral health problems on the lives of children and their families.

Objective

To evaluate the psychometric properties of ECOHIS applied to mothers of preschool children and estimate the influence of demographic characteristics, caries experience, and plaque index on the ECOHIS score.

Methods

The fit of ECOHIS to the data was assessed by confirmatory analysis. Chi-square for degrees of freedom ratio (χ2/df), Comparative Fit Index (CFI), Tucker-Lewis Index (TLI), and Root Mean Square Error of Approximation (RMSEA) were used. Reliability was estimated by the ordinal coefficients alpha (α) and omega (ω). The factorial invariance was estimated by the difference in CFI (ΔCFI). Comparisons of the ECOHIS mean scores according to the demographic characteristics, caries experience, and plaque index was performed using analysis of variance (ANOVA).

Results

A total of 371 children participated in the study. Mothers' mean age was 33.0 (SD = 7.04) years. The ECOHIS presented a good fit to the data (χ2/df = 4.31; CFI = 0.95; TLI = 0.94; RMSEA = 0.09) and a strict model invariance. Children without caries and from higher income class had lower oral health impact.

Conclusion

The data obtained with the ECOHIS were valid, reliable, and invariant. Children with caries experience and from lower income families had a greater impact of oral problems.

The Impact of Dental Pain on the Oral Health-Related Quality of Life (OHRQoL) of Preschool Children in Austria

Dental pain in children is a global public health burden with psychosocial and economic implications, challenging families and pediatric dentists in daily clinical practice. Previous studies have addressed the exclusive impact of either caries, dental trauma, malocclusion, or socioeconomic status on OHRQoL. Even though such examples can surely cause dental pain in children, so far only little research on the correlation of dental pain as a general symptom of different underlying causes and OHRQoL has been published. The aim of this study was to evaluate the impact of dental pain on the oral health-related quality of life (OHRQoL) of children between the ages of 0 and 6 years old and subsequently compare the results to a control group free of tooth ache. Children and their adult caregivers were recruited from the Emergency unit of the Department of Pediatric Dentistry at the University Clinic of Dentistry in Vienna. The caregivers completed the German version of the Early Childhood Oral Health Impact Scale (ECOHIS-G). Afterwards, the children were clinically examined. The cause for dental pain, dmf-t index, and plaque accumulation were collected. In total, 259 children with a mean age of 4.2 years (SD ± 1.5 years) were included in the study group. Their mean ECOHIS-G score was 9.0 (SD ± 7.4), while the control group only amounted to a score of 4.9 (SD ± 5.6). The difference between the two groups was statistically significant in both ECOHIS-G subsections, the child impact scale (CIS) and the family impact scale (FIS) as well as the ECOHIS-G sum score (p < 0.05). Dmf-t index and plaque accumulation significantly correlated with CIS and ECOHIS sum score (p ≤ 0.05). The reduction in quality of life was nearly twice as great in the children with dental pain as in the control children. The ECOHIS-G is a valid instrument for measuring the OHRQoL of children with dental pain between the ages of 0 to 6.

Psychometric properties of the Thai version of the Scale of Oral Health Outcomes for 5-year-old children

BACKGROUND

As caries prevalence in Thai preschool children is very high and its consequences have scarcely been evaluated, the Scale of Oral Health Outcomes for 5-year-old children (SOHO-5) is considered as an appropriate tool to measure the children's oral health-related quality of life (OHRQoL).

AIM

To translate the SOHO-5 into Thai (Th-SOHO-5) and assess its psychometric characteristics.

DESIGN

The cross-cultural adaptation of the SOHO-5 into Thai comprised forward-backward translation by experts and face validation by 20 child-parent dyads. To evaluate psychometric properties of the final version, a cross-sectional study was conducted on 306 child-parent pairs using an interview mode for children and a self-administered mode for parents. A trained investigator examined children's caries status.

RESULTS

The Th-SOHO-5 showed satisfactory psychometric characteristics. Cronbach's alpha values were above 0.8 for both child and proxy reports. Overall intraclass correlation coefficients were > 0.9. Factor analysis supported a single-factor structure model of the Th-SOHO-5 and showed an excellent fit. Th-SOHO-5 scores were correlated with all global rating scales of oral health and well-being. Children with higher caries experience or caries with pulpal involvement demonstrated significantly higher Th-SOHO-5 scores.

CONCLUSION

The Th-SOHO-5 possessed good reliability and validity. It can be used to evaluate the OHRQoL of preschool children in Thailand.

Health-related quality of life in patients with noma (cancrum oris): Case series

INTRODUCTION AND IMPORTANCE

Cancrum oris (noma) is a destructive disease of orofacial tissues and adjacent structures that progress rapidly, causing functional and cosmetic problems to the patient and ultimately affecting their health-related quality of life. This case series focuses on the impact of the cancrum oris on the health-related quality of life of patients which has been underreported in literature.

CASE PRESENTATION

Herein, we present 3 cases (1 pediatric and 2 adult patients) of cancrum oris. One adult male succumbed to the disease while the remaining two are undergoing treatment. We used the modified versions of the Early Childhood Oral Health Impact Scale (ECOHIS) and the University of Washington-Quality of Life (UWQoL) questionnaire for pediatric and adult patients respectively.

CLINICAL DISCUSSION

The sequela of cancrum oris affects negatively the quality of life of the patients even after definitive management. Despite this, there is no validated questionnaire to assess the quality of life. The modified versions of the ECOHIS and the UWQoL questionnaires that were used in this case report can be used effectively to assess the HRQoL of the patients.

CONCLUSION

Cancrum oris is a neglected disease that affects negatively the health-related quality of life of patients who suffer from it, despite medical intervention.

Psychometric evaluation of the Thai version of the Early Childhood Oral Health Impact Scale (Th-ECOHIS): a cross sectional validation study

Background

Early childhood caries (ECC) is prevalent in Thailand, but no appropriate tool has been available to measure its impact on children’s quality of life. This study translated the Early Childhood Oral Health Impact Scale (ECOHIS), a widely used proxy-reported questionnaire developed in the United States for measuring the oral health-related quality of life of preschool children and their families, into Thai (Th-ECOHIS). The scale’s psychometric properties were investigated in Thai caregivers and their children.

Methods

Cultural adaptation for the scale development within the Thai context was processed using forward–backward translation by experts. A face and content validation was conducted among 20 Thai caregivers to attain the final Th-ECOHIS. Psychometric testing was done on 3-year-old child-caregiver pairs in Bangkok using the interviewer-administered mode. Children’s oral health was determined by caries experience (decayed, missing and filled primary teeth, dmft) and treatment need. The caregivers answered the Th-ECOHIS and global questions regarding their perception of the children’s oral health. Across-items reliability was assessed by internal consistency using the Cronbach’s alpha coefficient. Test-retest reliability was managed at a 2-week interval in 10% of the sample using the intraclass correlation coefficient calculated by two-way analysis of variance. The discriminant validity was tested by the relationship between the severity of dental caries, treatment need and Th-ECOHIS scores, using the Kruskal-Wallis test.

Results

A total of 214 child-caregiver pairs participated. Twenty-two percent had ECC (dmft 1–3) and 17.3% had severe ECC (dmft 4 or higher) with mean (SD) dmft 1.63 (2.92). All items in the original ECOHIS were retained in the Thai version. The test-retest reliability of Th-ECOHIS was 0.87; internal consistency was 0.85; the total Th-ECOHIS scores were significantly correlated with the global rating of oral health question (r = 0.604). Th-ECOHIS scores in both child and family impact sections and the total were significantly associated with the severity of caries (p <  0.001) and treatment need (p <  0.001).

Conclusions

Th-ECOHIS demonstrated good reliability and validity. It could be used on caregivers to assess the impacts of ECC on quality of life of Thai pre-school children and compared to other countries.

Validation of the Chinese version of the Malocclusion Impact Questionnaire (MIQ)

OBJECTIVE

To translate and cross-culturally adapt the Malocclusion Impact Questionnaire (MIQ) into Chinese and to assess the psychometric properties of the Chinese version of the MIQ (MIQ/C) for use among adolescents with malocclusion in China.

MATERIALS AND METHOD

First, the MIQ/C was developed according to international guidelines. Then, the MIQ/C was filled out by 536 adolescents between 10 and 16 years of age. This study used exploratory factor analysis (EFA), confirmatory factor analysis (CFA), convergent validity, internal consistency, and test-retest reliability to evaluate the psychometric properties of the MIQ/C.

RESULTS

Following EFA, three domains were extracted, accounting for 65.950% of the total variance. The CFA results showed that the fit indices of each factor in the three-factor model all reached the standard (chi-square/DF = 2.591, GFI = 0.919, TLI = 0.926, CFI = 0.928, RMSEA = 0.076). The scale evidenced a good relationship with the two global questions, indicating good convergent validity. The Cronbach alpha value and the intraclass correlation coefficients (ICC) value of the MIQ/C were 0.929 and 0.893, respectively.

CONCLUSION

The MIQ/C demonstrated good reliability and validity and can be further studied and applied in Chinese adolescents with malocclusion.

CLINICAL RELEVANCE

The MIQ/C can be applied to assess the psychosocial impact of malocclusion among Chinese adolescents.
