Objectives: To investigate the impact of adaptive functioning and oral hygiene practices on tooth-brushing performance among preschool children with special health care needs (SHCN). Methods: A cross-sectional study was conducted in Special Child Care Centers. Children's tooth-brushing performance was assessed by a standardized 13-step pro forma. Information regarding children's socio-economic status, adaptive skills, and oral hygiene practices were collected. Bivariate analysis and ANCOVA were used to explore the potential factors which might be associated with children's tooth-brushing performance. Results: The tooth-brushing assessment was provided to 379 children with SHCN. Approximately 3% of the recruited children performed the whole tooth-brushing procedure independently. The number of tooth-brushing steps practiced by those children was 4.47 ± 3.56. Children who had established tooth-brushing habit before age one practiced more tooth-brushing steps than children who brushed their teeth after age one (p = 0.029). When children's age, gender, and socio-economic status were adjusted, children who had established regular tooth-brushing habit or children who had high levels of adaptive skills showed better tooth-brushing performance than their peers. Children who used gauze, cotton swab, or dental floss to clean their teeth practiced fewer key tooth-brushing steps than their peers who had never used additional cleaning approaches (p = 0.038). Conclusions for Practice: Children's tooth-brushing performance was associated with adaptive skills and oral hygiene practices. Tooth-brushing training should be provided to children with SHCN in early childhood. For children who had limitations in adaptive functioning, parental assistance or supervision is recommended to guarantee the efficacy and safety of daily tooth brushing. [ABSTRACT FROM AUTHOR]

Objective: To assess the oral health‐related quality of life among Hong Kong preschool children with severe early childhood caries. Methods: A total of 315 Hong Kong preschool children diagnosed with severe early childhood caries (S‐ECC) were recruited. Their caries and plaque status were evaluated. Their parents were asked to complete the Early Childhood Oral Health Impact Scale (ECHOIS) and a sociodemographic background questionnaire. Results: There was a 98.7% response rate. The mean age was 4.7 ± 0.8 years. The mean decayed, missing and filled teeth (dmft) score was 10.2 ± 4.5. Almost all the children (98.7%) had decayed teeth. More than half of the children (61.4%) had a visible plaque index (VPI) score of above 90%. About one quarter (28.9%) were experiencing symptoms of pain. The dmft score of the child was significantly associated with the ECOHIS child impact, child function, family impact and family distress domains (P < .001). The presence of pain was significantly associated with increased ECOHIS child and family impact scores (P < .001). In the multiple regression analyses, the dmft score and presence of pain showed a significant association with the ECOHIS scores (P < .001). Conclusion: The OHRQoL of children with S‐ECC was worsened with the presence of pain and severity of the disease. More measures need to be placed to decrease the prevalence of children with S‐ECC.

Patients’ perceived satisfaction is a key performance index of the quality health care service. Good communication has been found to increase patient’s perceived satisfaction. The purpose of this study was to examine the impact of the prominent themes arising from clinician-patient conversations on the caregiver’s perceived quality of communication during paediatric dental visits. 162 video recordings of clinical dental consultations for 62 cases attending the Paediatric Dentistry Clinic of The Prince Philip Dental Hospital in Hong Kong were captured and transcribed. The patients’ demographic information and the caregiver’s perceived quality of communication with the clinicians were recorded using the 16-item Dental Patient Feedback on Consultation skills questionnaires. Visual text analytics (Leximancer™) indicated five prominent themes ‘disease / treatment’, ‘treatment procedure related instructions’, ‘preparation for examination’, ‘positive reinforcement / reassurance’, and ‘family / social history’ from the clinician-patient conversation of the recorded videos, with 60.2% of the total variance in concept words in this study explained through principal components analysis. Significant variation in perceived quality of communication was noted in five variables regarding the prominent theme ‘Positive reinforcement / reassurance’: ‘number of related words’ (p = 0.002), ‘number of related utterances’ (p = 0.001), ‘percentage of the related words in total number of words’ (p = 0.005), ‘percentage of the related utterances in total number of utterances’ (p = 0.035) and ‘percentage of time spent in total time duration’ (p = 0.023). Clinicians were perceived to be more patient-centered and empathetic if a larger proportion of their conversation showed positive reinforcement and reassurance via using related key words. Care-giver’s involvement, such as clinicians’ mention of the parent, was also seen as critical to perceptions of quality clinical experience. The study reveals the potential of the application of visual text analytics software in clinical consultations with implications for professional development regarding clinicians’ communication skills for improving patients’ clinical experiences and treatment satisfaction.

Objectives Studies investigating influencing factors of permanent tooth eruption/emergence have primarily focused on anthropometric measurements while less attention has been paid to the effect of perinatal factors. We aimed to explore early factors associated with eruption status of permanent teeth among 12-year-olds through a population-representative prospective cohort. Methods A community sample of Hong Kong children born in 1997 was obtained by random sampling from local secondary schools. Participants' background information including birth characteristics, prenatal and early childhood exposures, family socioeconomic status and medical records was prospectively collected. Clinical examination of tooth emergence was conducted in 2010. Children were divided into complete emergence (of 28 permanent teeth) and partial emergence groups based on clinical examinations. Bivariate analyses were used to assess the association of tooth emergence status with each putative predictor. Unadjusted and adjusted logistic regression models were applied to select the best predictors for tooth emergence status at age 12. Results Complete background information and clinical data were available from 514 children (76.9% of the invited participants). Bivariate analyses showed that the average birthweight in the partial emergence group was significantly lower than the complete emergence group (mean difference 0.2 kg, P = 0.006). The finding was confirmed by logistic regression analyses. In the adjusted regression model, it was found that for every 1 kilogram increase in birthweight, the odds of having partial emergence would be lowered by 0.49 (odds ratio 0.49, P = 0.006). Conclusions Birthweight is associated with status of permanent tooth emergence at 12 years of age, as observed from a population-representative sample of Hong Kong children. [ABSTRACT FROM AUTHOR]

Background/purpose Dental anxiety is closely related to one's past experience in dental clinics. However, little is known about what clinical, environmental, and psychological aspects provoke anxiety in dental patients. Extending on previous work in The Netherlands which explored anxiety provoking stimuli, the objective of the study was to develop a Dental Anxiety Provoking Scale (DAPS) that measures the degree to which anxiety was provoked by dental stimuli and to identify the underlying factor structure of the DAPS. Materials and methods Four hundred and sixty study participants were recruited from two universities in Hong Kong. Each participant completed a self-administrated questionnaire that included a 73-item measure of dental anxiety provoking stimuli, and a four-item dental anxiety scale. Results Results of exploratory and confirmatory factor analyses showed that the DAPS has seven factors, namely, dental check-up, injection, scale and drill, surgery, empathy, perceived lack of control, and clinic environment, and has 27 items. Results of structural equation modeling showed that three factors of the DAPS; dental check-up, surgery, and clinic environment, had a significant effect on dental anxiety score. The Cronbach α values ranged from 0.76 to 0.92 while the composite reliability values ranged from 0.78 to 0.93. The average variance extracted (AVE) values ranged from 0.55 to 0.81. The minimum AVE value was greater than the square of correlation value for each pair of factors. Conclusion The study developed and validated the DAPS covering a wide range of dental anxiety provoking stimuli, findings were concise enough to be used in clinical based studies.

Background Oral health literacy is a newly emerging field with considerable research potential. Aim To validate an original instrument, the Hong Kong Oral Health Literacy Assessment Task ( HKOHLAT-P) for paediatric dentistry. Design A convenient sample of 200 child/parent dyads attending a dental hospital in Hong Kong was selected. Convergent validity was tested by examining the association of HKOHLAT-P scores with those derived from the Test of Functional Health Literacy in Dentistry ( TOFHLi D) and Hong Kong Rapid Estimate of Adult Literacy in Dentistry ( HKREALD-30). The predictive validity of HKOHLAT-P was determined by testing the association between HKOHLAT-P and children's caries experience (dmft) and the Chinese Early Childhood Oral Health Impact Scale ( ECOHIS). The test-retest reliability and internal consistency of HKOHLAT-P were also evaluated. Results HKOHLAT-P was positively correlated with TOFHLi D and HKREALD-30 ( P < 0.01), and was negatively correlated with children's dmft and ECOHIS. In the regression model, HKOHLAT-P was associated with TOFHLi D, HKEALD-30, children's dmft, and ECOHIS ( P < 0.05) after controlling for participants' demographic characteristics. The intra-class correlation coefficient of HKOHLAT-P was 0.63 and the Cronbach's α was 0.71. Conclusion Initial testing of HKOHLAT-P suggested that it is a valid and reliable instrument.

Aim: To develop and validate an instrument, the Hong Kong Rapid Estimate of Adult Literacy in Dentistry (HKREALD-30). Methods: The Rapid Estimate of Adult Literacy in Dentistry (REALD-99) was translated into Chinese and modified in the pretest. A total of 200 parents of pediatric dental patients were interviewed using this modified scale and administered additional three sets of self-reported questionnaires. The 99 items of the scale were reduced to 30 (HKREALD-30). Concurrent validity was tested by comparing the HKREALD-30 scores with the participants' educational level, pattern of dental visits and reading habits. Convergent validity was tested by examining the association between HKREALD-30 and the Test of Functional Health Literacy in Dentistry (TOFHLiD). The test-retest reliability and internal consistency of HKREALD-30 were also evaluated. Results: A significant correlation ( P < 0.01) was found between HKREALD-30 and participants' reading habits. HKREALD-30 was also highly correlated with TOFHLiD (Spearman's rho = 0.693, P < 0.01). In the regression model, HKREALD-30 was positively associated with TOFHLiD ( P < 0.05) after controlling for participants' characteristics. The intra-class correlation coefficient of HKREALD-30 was 0.78 and the Cronbach's alpha was 0.84. Conclusion: Initial testing of HKREALD-30 suggested that it is a valid and reliable instrument for the basic screening of oral health literacy among Chinese people in Hong Kong.

Background: There is no consensus opinion regarding the association between obesity and periodontal diseases among children and adolescents in the literature. Methods: A prospective observational cohort study was conducted in a Hong Kong cohort at age 12, 15 and 18. CPI and various obesity indices including BMI, WC, WHR, WHtR, and TRSKF were recorded during each wave of data collection. Information on socioeconomic status and oral health behaviors were collected through self-completed questionnaires. Results: Two hundred and eighty-two (male: 122 and female: 160) participants completed all three rounds of data collection. Prevalence of overweight/obesity was 27.0, 19.1, and 14.2% at 12, 15, and 18 years, respectively. 19.9% participants had healthy periodontal conditions at age 12. While the percentage dropped to 10.3% at 15 years and 5.7% at 18 years. The proportion of 15-year-old adolescents who brushed teeth more than twice a day was significantly higher among participants belonging to the lower BMI, WC, WHR, and WHtR category (P < 0.05). The fully adjusted model revealed that participants with lower BMI at age 15 had higher probability of having more than 50% index teeth free from periodontal diseases at age 18 (OR: 2.78; 95% CI: 1.16, 6.64; P = 0.022). Conclusions: Although higher BMI at 15 years was associated with more extensive periodontal inflammation at age 18, this was believed to be an indirect association confounded by the poor oral health care among overweight/obese individuals. Oral health promotions should be directed to improve periodontal conditions of overweight/obese secondary school students. [ABSTRACT FROM AUTHOR]

Background: Socio-economic status, health awareness, and dietary habits have been reported as common risk factors of dental caries and obesity. The present study aimed to explore shared mediators between caries and obesity and to estimate the effects of caries-related factors on adiposity. Methods: This was a cross-sectional study among adolescents aged 18 years. The study was nested in a population-representative cohort of Chinese in Hong Kong. The number of decayed, missing, and filled permanent teeth (DMFT) was recorded during the oral examinations. Body Mass Index (BMI), Waist Circumference (WC), Waist-Hip-Ratio (WHR), Waist-Height-Ratio (WHtR), and Triceps Skinfold Thickness (TRSKF) were used as adiposity indices. Data on socio-economic status, oral health behavior (tooth brushing habit, use of fluoride toothpaste, dental flossing habit, and mouth rinse habit), and dietary record (frequency and amount of different food) were collected through self-completed questionnaires. Chi-square tests and binary logistic regressions were used for analysis. Results: Three hundred eighty-three participants were included. The mean (standard deviation, SD) of BMI, WC, WHR, WHtR, TRSKF, and DMFT were 21.26 (3.72), 69.11 (9.25), 0.77 (0.06), 0.42 (0.05), 15.72 (6.33), and 2.06 (2.43), respectively. Males were more likely to be overweight/obese than females. Various factors including gender, parental employment status, mouth rinse habit, frequency and amount of meat intake, frequency of oil intake, use of fluoride toothpaste, and DMFT were found significant (p < 0.05) in different final models of adiposity status. Conclusions: More mediators should be included in future research to elucidate mechanism of the association between caries and obesity. [ABSTRACT FROM AUTHOR]

Background: The development of primary dentition can be affected by oral sucking habits. Therefore, this study aims to investigate the association of nutritive and non-nutritive sucking habits with primary dentition development. Methods: One thousand one hundred and fourteen children aged 2 to 5 years old in Hong Kong were recruited in a cross-sectional study. Information on their nutritive (e.g. breastfeeding and bottle feeding) and non-nutritive sucking habits (e.g. pacifier use and thumb/digit sucking) was collected via questionnaires. The children’s primary occlusions were examined in three dimensions. Results: Children who were breastfed for more than 6 months had a lower proportion of daily pacifier use (p < 0.05). Children who used pacifiers daily had a higher proportion of thumb/digit sucking (p < 0.05). Children who used pacifiers daily for more than one year had higher chances of developing an anterior open bite (p < 0.05) and a reduced overbite (p < 0.05). Those exhibiting daily thumb/digit sucking for more than one year had higher chances of developing Class II incisor and Class II canine relationships, an increased overjet and anterior open bite (p < 0.05). Conclusion: Pure breastfeeding for more than 6 months is inversely associated with daily pacifier use and daily pacifier use is positively associated with daily thumb/digit sucking. Children with more than one year of daily pacifier use and thumb/digit sucking have higher chances of developing abnormal dental relationships in the sagittal (i.e. Class II incisor and Class II canine relationships and increased overjet) and vertical (i.e. anterior open bite) dimensions, respectively.
