Parental Perception of Oral Health and Oral Health Status of Pediatric Patients Attending an Urban Craniofacial Center

OBJECTIVE

The objectives of this study were to assess the oral health status and parental perception of oral health needs of pediatric patients in an urban Craniofacial Center.

DESIGN

This research utilized a prospective cross-sectional matched study design. The data was collected prospectively via clinical oral examinations measuring dental caries experience and gingival health status. Parental perception of oral health was assessed through a validated questionnaire.

SETTING

The study was conducted at a Pediatric Dentistry Department and Craniofacial Center (CFC) in a large urban American city.

PATIENTS/PARTICIPANTS

Participants were recruited and enrolled from a CFC and Pediatric Dental Clinic.

MAIN OUTCOME MEASURE(S)

The outcome measures were the oral health status and parental perception thereof.

RESULTS

CFC patients' caries experience in primary teeth was significantly lower than that of a healthy matched cohort, but statistically similar in permanent teeth. CFC patients had significantly higher unmet dental treatment needs. CFC patients had poor oral hygiene and were shown to have significantly higher plaque levels and worse gingival health than that of a healthy matched cohort. Parental perception of oral health did not show a statistically significantly difference between the two groups.

CONCLUSIONS

Patients in our study in an urban CFC were found to have a high unmet dental and poor oral hygiene. Despite the poor oral health status, parents of children with craniofacial anomalies did perceive their oral health as different from a matched cohort of patients without these conditions.

Perception of Special-Care Dentistry among Dental Students at Universitas Indonesia: A Cross-Sectional Study

OBJECTIVE

To assess the perceptions of special-care dentistry (SCD) among dental students in the Faculty of Dentistry, Universitas Indonesia, Indonesia.

METHODS

This cross-sectional study used a self-administered online questionnaire, and all preclinical and clinical students were invited to participate. The survey items comprised four domains related to participants' characteristics, perceptions of SCD, perceptions of managing patients with special needs, and perceptions of SCD education. The chi-square test and Mann-Whitney test were used in the analysis.

RESULTS

A total of 572 students participated in this study. The findings showed that the clinical students were more familiar with SCD than the preclinical students were (p = 0.008). A statistically significant relationship was found between the study program and the ability to work independently with special-needs patients after graduation (p < 0.001), the ability to refer special-needs patients to specialists (p = 0.042), the perception of postgraduate training-program needs (p < 0.001), and the opportunity to consider postgraduate training (p = 0.004).

CONCLUSION

Most of the respondents had a favorable perception of SCD. Thus, an improved SCD curriculum and SCD training for undergraduate and postgraduate students should be provided to develop the knowledge and skills needed to provide care to special-needs patients.

Oral Health Among Children and Youth With Special Health Care Needs

OBJECTIVES

We sought to estimate the prevalence of oral health problems and receipt of preventive oral health (POH) services among children and youth with special health care needs (CYSHCN) and investigate associations with child- and family-level characteristics.

METHODS

We used pooled data from the 2016-2018 National Survey of Children's Health. The analytic sample was limited to children 1 to 17 years old, including 23 099 CYSHCN and 75 612 children without special health care needs (non-CYSHCN). Parent- and caregiver-reported measures of oral health problems were fair or poor teeth condition, decayed teeth and cavities, toothaches, and bleeding gums. POH services were preventive dental visits, cleanings, tooth brushing and oral health care instructions, fluoride, and sealants. Bivariate and multivariable logistic regression analyses were conducted.

RESULTS

A higher proportion of CYSHCN than non-CYSHCN received a preventive dental visit in the past year (84% vs 78%, P < .0001). Similar patterns were found for the specific preventive services examined. However, CYSHCN had higher rates of oral health problems compared with non-CYSHCN. For example, decayed teeth and cavities were reported in 16% of CYSHCN versus 11% in non-CYSHCN (P < .0001). In adjusted analyses, several factors were significantly associated with decreased prevalence of receipt of POH services among CYSHCN, including younger or older age, lower household education, non-English language, lack of health insurance, lack of a medical home, and worse condition of teeth.

CONCLUSIONS

CYSHCN have higher rates of POH service use yet worse oral health status than non-CYSHCN. Ensuring appropriate use of POH services among CYSHCN is critical to the reduction of oral health problems.

The optimal orthodontic displacement of clear aligner for mild, moderate and severe periodontal conditions: an in vitro study in a periodontally compromised individual using the finite element model

Background

Pathologic tooth migration (PTM) is a common complication of mild to severe periodontitis and proper orthodontic treatment is helpful to alleviate periodontal diseases. The goal of this study is to explore an optimal orthodontic displacement of clear aligner using a three-dimensional (3D) finite element model (FEM).

Methods

The cone beam computed tomography (CBCT) data of a patient received invisible orthodontics without diabetes and other systemic diseases were collected. Based on the new classification scheme for periodontal diseases in 2017 (stage I: mild periodontitis, [M1]; stage II: moderate periodontitis, [M2]; stage III: severe periodontitis, [M3]), 3D-FEMs of mandible were established using MIMICS 10.0 and ABAQUS 6.5 softwares. The 3D stress distribution diagrams and stress value of the teeth (left lower incisor, left lower central incisor, right lower lateral incisor, and right lower central incisor) under three different periodontal conditions (M1, M2, and M3) with axial inclination 90° and 100° were obtained by ABAQUS 6.5.

Results

The stress of anterior teeth was concentrated in the teeth neck, and became greater when the periodontal condition was worse. The stress value of anterior teeth and the strain at the top of the alveolar crest are greater as the displacement increasing. The stress value of anterior teeth and the strain at the top of the alveolar crest in axial inclination 100° are relatively great compared to those of axial inclination 90°. For patients with excessively inclined anterior teeth (such as 100°), the optimal orthodontic displacement is 0.18 mm. In order to ensure that alveolar ridge crest is not deformed, the displacement is less than 0.18 mm (strain for 0.165 mm), 0.15 mm (strain for 0.167 mm) and 0.10 mm (strain for 0.117 mm) respectively when alveolar bone is normal, resorption 1/3 or 1/3–1/2.

Conclusions

The optimal orthodontic displacement for patients (M1, M2, and M3) with excessively inclined anterior teeth (axial inclination 100°) is 0.18 mm. To avoid the strain at the top of the alveolar crest, the optimal displacements for M1, M2 and M3 periodontal disease patients are less than 0.18 mm, 0.15 mm and 0.10 mm, respectively.

A Comprehensive Approach Limiting Extractions under General Anesthesia Could Improve Oral Health

Access to dental treatment could be difficult for some patients due to dental phobia or anxiety, cognitive or sensorial disabilities, systemic disorders, or social difficulties. General anesthesia (GA) was often indicated for dental surgery, and there is almost no available data on adapted procedures and materials that can be applied during GA for maintaining functional teeth on the arches and limiting oral dysfunctions. This study evaluates changes in oral health-related quality of life and mastication in a cohort of uncooperative patients treated under GA according to a comprehensive and conservative dental treatment approach. Dental status, oral health-related quality of life, chewed bolus granulometry, kinematic parameters of mastication, and food refusals were evaluated one month preoperatively (T0), and then one month (T1) and six months post-operatively (T2). One hundred and two adult patients (mean age ± SD: 32.2 ± 9.9 years; range: 18–57.7) participated in the preoperative evaluation, 87 were treated under GA of which 36 participated in the evaluation at T1 and 15 were evaluated at T2. Preoperative and postoperative data comparisons demonstrated that oral rehabilitation under GA helped increase chewing activity and oral health-related quality of life. The conditions for providing dental treatment under GA could be arranged to limit dental extractions in uncooperative patients.

Oral health and associated factors among preschool children with special healthcare needs

OBJECTIVE

To investigate the oral health status and associated factors among preschool children with special healthcare needs.

SUBJECTS AND METHODS

This was designed as a cross-sectional study. Dental examination was provided to 383 children at Special Child Care Centres. Covariates of interest included children's age, developmental profile, oral health-related behaviours and family social-economic status. The association between children's dental caries experiences, dental plaque deposition and gingival health status were analysed by negative binomial regression, multiple factor ANOVA and binary logistic regression when appropriate.

RESULTS

The proportion of children with caries, gingival inflammation and plaque were 30.3%, 89.6% and 95.0%, respectively. Final regression models indicated that (a) tooth decay was associated with dental visit experiences, night bottle-feeding habit, fluoridated toothpaste and monthly income; (b) plaque deposition was associated with intellectual functioning, practical skills, night bottle-feeding habit, use of toothpaste, initiation of toothbrushing habit, toothbrushing duration and additional cleaning habit; (c) gingival status was associated with children's intellectual functioning and toothbrushing frequency.

CONCLUSIONS

Poor oral hygiene status existed among preschool children with special healthcare needs. Children's oral health status was associated with their developmental profile, oral health-related behaviours and social-economic status.

Predictive data mining for diagnosing periodontal disease: the Korea National Health and Nutrition Examination Surveys (KNHANES V and VI) from 2010 to 2015

OBJECTIVES

This study aimed to identify patients with the highest risk of periodontal disease (PD), and to provide recommendations for the effective use and application of data mining (DM) techniques when establishing evidence-based dental-care policies for vulnerable groups at a high risk of PD.

METHODS

This study used the SEMMA (Sample, Explore, Modify, Model, and Assess) methodology to construct DM models based on data acquired from the fifth and sixth Korea National Health and Nutrition Examination Surveys (2000-2015). We analyzed the sociodemographic and comorbidity variables that influence PD by applying the popular DM techniques of decision-tree, neural-network, and regression models, and also attempted to improve the predictive power and reliability by comparing the results obtained by these three models.

RESULTS

Our comparisons of the three DM algorithms confirmed that the average squared error, misclassification rate, receiver operating characteristic index, Gini coefficient, and Kolmogorov-Smirnov test results were the most appropriate for the decision-tree model. The analysis of the decision-tree model revealed that age and smoking status exert major effects on the risk of PD, and that stress and education level exert effects in rural areas, whereas education level, sex, hyperlipidemia, and alcohol intake exert effects in urban areas.

CONCLUSIONS

We demonstrated that the decision-tree model is an effective DM technique for identifying the complex risk factors for PD. These results are expected to be helpful in improving the equality and efficacy of dental-care policies for vulnerable groups at a high risk of PD.
