Abstract
Introduction Malocclusion, a common oral health problem in children, is associated with several contributing factors. This study aimed to investigate the prevalence of mixed dentition stage malocclusion and its contributing factors in Chinese Zhuang children aged 7-8 years. Methods Overall, 2,281 Zhuang children, about 7-8 years old, were randomly selected using a stratified whole-cluster sampling method from schools in counties in Northwestern Guangxi, China. The children were examined on-site for malocclusion and caries by trained dentists, and basic data on the children were collected using questionnaires, including age, sex, parental education, parental accompaniment, and children's knowledge of malocclusion and treatment needs. Data were analyzed using the chi-square test and logistic regression analysis. Results The total prevalence of malocclusion in Zhuang children aged 7-8 years was 58.5%, with the highest prevalence of anterior crossbite tendency, and the prevalence of anterior crossbite and anterior edge-to-edge occlusion was 15.1% and 7.7%, respectively. This was followed by an anterior increased overjet of 13.3% and an inter-incisor spacing of 10.3%. The lowest prevalence was 2.7% for anterior open bite. Sex, parental accompaniment, parental education, and decayed, missing, and filled teeth of the first primary molar were factors that contributed to malocclusion in Zhuang children. Conclusion Malocclusion is a common oral problem among Zhuang children. Therefore, more attention must be paid to the intervention and prevention of malocclusion. The impact factors should be controlled as early as possible.

Abstract
INTRODUCTION This study aimed to investigate the esthetic impact of mandibular crowding and maxillary midline diastema in children in the mixed dentition. METHODS The sample for this cross-sectional study comprised 785 children, aged 8-10 years, in the late mixed dentition. Mandibular crowding and maxillary midline diastema were evaluated clinically with the Dental Aesthetic Index. Mandibular crowding and maxillary midline diastema were evaluated to determine tooth size-arch length discrepancies. The sample was stratified as group 1, children without maxillary midline diastema or mandibular crowding (n = 177); group 2, children with maxillary midline diastema (n = 256); group 3, children with mandibular crowding (n = 208); and group 4, children with maxillary midline diastema and mandibular crowding (n = 144). The subjective esthetic impact was evaluated using the Orthodontic Aesthetic Subjective Impact Score. Descriptive and exploratory analyses of the data were performed. A generalized linear model was applied, adjusted for the possible confounding variables (age, gender, and race) with a significance level of 5% because the Orthodontic Aesthetic Subjective Impact Score did not meet the assumptions of analysis of variance. RESULTS Children in groups 2 and 3 showed greater esthetic concern than group 1 (P <0.05). Children in groups 2 and 3 did not show a significant difference with children in group 4 (P >0.05). CONCLUSIONS Children with mixed dentition with mandibular crowding or maxillary median diastema reported significantly more esthetic concern than children without these conditions.

Abstract
Objective To determinate the association among socioeconomic status subject’s mother’s level of educational attainment, dental visits, and malocclusion in mixed dentition with on the OHRQoL of eight-to-ten-year-old children. Methods A cross-sectional study conducted, in 2019, on Mexican children from households of different socioeconomic status (SES). The prevalence of malocclusion was evaluated using the Dental Aesthetic Index (DAI), while the SES of the participants’ households was evaluated using the three categories (corresponding to a high, middle, or low-income household) stipulated by the Consejo Nacional de Población (CONAPO or National Population Council). Oral Health-related Quality of Life (OHRQoL) was evaluated using the Child Perceptions Questionnaire (CPQ8-10). Poisson regression models were performed for the analysis of the data obtained. Results A total of 79.4% of the subjects presented some type of malocclusion in mixed dentition, which was, by severity, as follows: definite (31.3%); severe (25.6%); and, very severe (22.5%). The Poisson regression model revealed a greater negative impact on the following four CPQ8-10domains for children with severe/very severe malocclusion [RR]: oral symptoms [2.78]; functional limitations [2.72]; emotional well-being [2.59]; and, social well-being [3.99]. A greater impact on the four CPQ8-10domains was found for children from a low-income household than for children from a high-income (p < 0.001) household. Furthermore, poor oral hygiene, lack of dental visits, and the mother’s level of educational attainment (<9 years) were found to have a negative impact on OHRQoL. Conclusion The findings of the present study demonstrated that the severity of malocclusion was associated with a greater negative impact on the OHRQoL of children, while those children who face greater health inequalities are likely to report a greater negative impact on their OHRQoL.

Abstract
We aimed to assess the impact of malocclusion on oral health-related quality of life (OHRQoL) in a sample composed of adolescents, younger adults and adults seeking orthodontic treatment. Participants were consecutively enrolled from January 2019 to March 2020. The oral health impact profile (OHIP-14) was used to measure the OHRQoL. The index of complexity, outcome and need (ICON) was used to assess malocclusion. Sociodemographic, medical, and clinical questionnaires were recorded. Statistical analyses were performed according as a function of sex and age range (15-30 or >30 years old). Linear and logistic regression models were applied to assess the association between OHIP-14 total score, malocclusion, and other relevant confounding variables. In a final sample of 93 participants (60 females and 33 males, aged 15 to 60 years), men reported significantly better OHRQoL (p = 0.005). Participants aged 30 years or older reported significantly worse OHRQoL (p = 0.042). OHIP-14 was significantly correlated with age (ρ = 0.259, p < 0.05) and the number of missing teeth (ρ = 0.369, p < 0.001). Multivariable regression showed OHIP-14 being associated with the number of missing teeth (B = 1.48, SE = 0.57, p < 0.05) and the presence of missing teeth (B = 1.38, SE = 0.65, p < 0.05). Malocclusion showed no association with OHRQoL. Age and the number of missing teeth may be key factors on self-perceived OHRQoL in adult patients seeking orthodontic treatment.

Abstract
INTRODUCTION Our study objectives were to evaluate the impact of malocclusion on oral health-related quality of life (OHRQOL) of adolescents aged 11-14 years in Ile-Ife, Nigeria. METHODS Two hundred adolescents completed the Child Perceptions Questionnaire: Impact Short Form (CPQ11-14-ISF:16) and the Malocclusion Impact Questionnaire (MIQ). The Aesthetic Component of the Index of Orthodontic Treatment Need scale was used to determine malocclusion severity. The effect of sex, age, and socioeconomic class on OHRQOL were determined with the Mann-Whitney U test, Kruskal-Wallis H test, correlation tests, and multiple regression analysis using SPSS (version 22.0; IBM, Armonk, NY). Statistical significance was set at P <0.05. RESULTS The CPQ11-14-ISF:16 and MIQ identified the impact of malocclusion on OHRQOL with mean (standard deviation) scores of 12.85 (10.17) and 8.33 (7.50), respectively. Sex, socioeconomic class, and malocclusion severity had no significant effect on OHRQOL (P >0.05); however, OHRQOL differed significantly between the age groups (CPQ11-14-ISF:16, P = 0.002; MIQ, P = 0.041). Multiple regression analysis showed that age was a significant predictor of OHRQOL determined with CPQ11-14-ISF:16 (standardized coefficients B score = -0.242, P = 0.001). MIQ demonstrated good criterion validity with CPQ11-14-ISF:16 (r = 0.59, P <0.001). CONCLUSIONS Both measures CPQ11-14-ISF:16 and MIQ identified the impact of malocclusion on the OHRQOL of adolescents. Sex, socioeconomic class, and malocclusion severity did not affect OHRQOL; however, age was a significant predictor of OHRQOL. Further studies among orthodontic patient populations are desirable.

Abstract
INTRODUCTION This study aimed to associate 2 indexes for evaluating malocclusion in the mixed dentition. METHODS A population-based cross-sectional study was conducted involving 743 children aged 8-10 years, divided into early and late mixed dentition. The Dental Aesthetic Index (DAI) and criteria proposed by Grabowski were used to evaluate malocclusion. Associations between the DAI (outcome variable) and the other independent variables (gender, race, and mixed dentition stage) were analyzed using logistic regression models. Simple logistic regression models were constructed, estimating the crude odds ratios with the respective 95% confidence intervals (CIs). The variables with P < 0.20 in the simple analyses were tested in multiple logistic regression models, estimating adjusted odds ratios with the respective 95% CIs. RESULTS We found that 84.01% (185/220) of the diagnoses were coincidental between the Grabowski Index and DAI in patients without malocclusion. In contrast, 59.80% (439/734) of the patients were diagnosed by both indexes (Grabowski and DAI) with malocclusion. Children with malocclusion, diagnosed by the Grabowski Index, were 5.85 (P = 0.0001 and 95% CI: 4.08-8.39) times more likely to show malocclusions when diagnosed by the DAI. CONCLUSIONS DAI and the criteria proposed by Grabowski were expressed differently in relation to malocclusion in the mixed dentition. This study suggests the importance of specific criteria for the evaluation of malocclusion at this stage of development.

Abstract
INTRODUCTION To assess the esthetic subjective effect of malocclusions in the anterior segment on children in the mixed dentition. METHODS A cross-sectional study was carried out with a population-based sample of 787 children aged 8-10 years in the late mixed dentition (n = 787). Orthodontic Aesthetic Subjective Impact Score determined the esthetic subjective effect. For assessing the malocclusions in the anterior segment (anterior crowding, anterior spacing, diastema, anterior open bite, and anterior maxillary overjet), the following Dental Aesthetic Index criteria were used. Sex, family income, and education level were used as control variables. The variables were analyzed using a simple logistic regression model, estimating crude odds ratios. The variables with P <0.20 in the simple analyses were tested in multiple regression models, estimating adjusted odds ratios with the respective 95% confidence intervals. RESULTS Increased overjet was 1.54 (95% CI: 1.08-2.17) times more likely to cause greater esthetic concern (P <0.05), especially in girls (P <0.05). CONCLUSIONS Increased overjet negatively affected children's esthetic self-perception in the mixed dentition.

Abstract
OBJECTIVES To evaluate the impact of anterior occlusal conditions in the mixed dentition on item-level analysis of oral health-related quality of life (OHRQoL). MATERIALS AND METHODS A population-based cross-sectional study of 787 children aged 8 to 10 years was conducted. The Child Perceptions Questionnaire (CPQ8-10) was used to evaluate OHRQoL, and the analysis of item levels was performed on CPQ8-10 domains. Anterior occlusal characteristics were diagnosed according to the Dental Aesthetic Index criteria. Individual analyses were performed relating the outcome as independent variables. The variables with P < .20 in the individual analyses were tested in multiple logistic regression models, and those with P < .10 remained in the model. The adjusted odds ratio (OR) was estimated with a 95% confidence interval (CI). RESULTS No associations were found with regard to anterior occlusal characteristics (P < .001) after the variables of the previous determinants were adjusted for multivariate analysis. However, the following variables were significantly associated with negative impact on OHRQoL item levels: sex, in oral symptoms (OR = 1.42; CI, 1.07-1.89) and emotional well-being (OR = 1.34; CI, 1.00-1.79); race, in oral symptoms (OR = 1.48; CI, 1.10-1.98), emotional well-being (OR = 1.54; CI, 1.14-2.06), and social well-being (OR = 1.34; CI, 1.00-1.80); and family income in functional limitation (OR = 1.46; CI, 1.06-2.02), emotional well-being (OR = 1.71; CI, 1.21-2.42), and social well-being (OR = 1.59; CI, 1.14-2.21). CONCLUSIONS Anterior occlusal conditions did not affect the levels of OHRQoL items.

Abstract
There is a lack of evidence of the moderating effects of caries lesions and malocclusions on oral health-related quality of life (OHRQoL) among older adolescents. This study aimed to evaluate the relationship of dental caries and malocclusion with OHRQoL among Lithuanian adolescents aged 15 to 18 years. A survey in a representative sample of adolescents included a clinical examination to assess dental health status using the DMFT (Decayed, Missing, and Filled Permanent Teeth) index, and malocclusion using the Index of Complexity, Outcome, and Need (ICON). The Child Perceptions Questionnaire (CPQ) was used to evaluate respondents’ OHRQoL. Negative binomial regression was fitted to associate the clinical variables with the CPQ scores. A total of 600 adolescents were examined. The overall mean DMFT score was 2.7. A need for orthodontic treatment was detected among 27.7% of adolescents. Subjects with caries lesions (DMFT > 3) had higher CPQ scores in the domains of functional limitations and social wellbeing (relative risks were 1.35 (95% confidence interval: 1.09–1.67) and 1.30 (1.03–1.64), respectively), while subjects with a need for orthodontic treatment (ICON > 43) had higher CPQ scores in the domains of emotional wellbeing and social wellbeing (relative risks were 1.81 (1.40–2.22), and 1.69 (1.34–2.14), respectively). It was concluded that both dental caries and malocclusion have negative relationships with OHRQoL in adolescents above 15 years, but their effects occur differently in each OHRQoL domain.

[PMID: 31677307 DOI: 10.1111/ipd.12591] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2019] [Revised: 09/13/2019] [Accepted: 10/27/2019] [Indexed: 01/05/2023]
Abstract
BACKGROUND Malocclusion is a common oral health problem in schoolchildren. Literature describing the prevalence of malocclusion varies substantially across China. AIM This study identified the epidemiological characteristics of malocclusion among Chinese schoolchildren from 1991 to 2018. DESIGN Six English and Chinese electronic databases were searched through November 2018. The search was supplemented by hand searching to identify relevant surveys. The overall prevalence of malocclusion was estimated by a random-effects meta-analysis model, and variations in different groups were assessed by subgroup meta-analysis. RESULTS Thirty-seven eligible articles describing 117 682 samples were investigated. The pooled national prevalence for malocclusion was 47.92% (95% CI: 58.6%-71.9%). For the Angle classification, the overall prevalence rates were 30.07% (95% CI: 25.37%-35.48%), 9.91% (95% CI: 7.41%-13.79%), and 4.76% (95% CI: 3.85%-6.54%) for Class I, Class II, and Class III malocclusion, respectively. A deep overbite (16.67%, 95% CI: 11.50%-23.08%) was shown to be the most common trait of malocclusion. When stratified by sex, males had a slightly higher prevalence than females (RR = 1.04, 95% CI: 1.01-1.06). More importantly, an ascending trend and substantial variations across the country were observed. CONCLUSIONS Our results confirmed that malocclusion has become a serious oral health problem in Chinese schoolchildren, highlighting the need for proactive interventions at an early age. Moreover, high-quality epidemiological studies on malocclusion are still required.

J Int Soc Prev Community Dent 2019; 9:72-76. [PMID: 30923697 PMCID: PMC6402251 DOI: 10.4103/jispcd.jispcd_350_18] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2018] [Accepted: 12/06/2018] [Indexed: 11/20/2022] Open
Abstract
Aims and Objectives: Discomfort associated with the use of fixed orthodontic appliances may have a negative influence on the patient's oral health-related quality of life (OHRQoL). In general, OHRQoL assessments have the potential to provide information on the need to improve the overall quality of care. This study aims to assess the impact of fixed orthodontic appliances on OHRQoL of Saudi population and to explore the impact of the patient's gender and age on perceived treatment. Subjects and Methods: This cross-sectional study used a generic measure of OHRQoL the Arabic version of the Oral Health Impact Profile (OHIP-14), which is a responsive measure to changes in oral health conditions. Data were collected using self-completed e-questionnaire which was distributed through social media and were analyzed using Statistical Package for Social Sciences (SPSS) version 21.0. Results: A total of 149 subjects, 110 (73.8%) were females and 39 (26.2%) were males. Adolescents between 13 and 20 years were 63 (42.3%) and adults between 21 and 30 years were 86 (75.7%). A response rate of 100% was obtained. The prevalence of oral health impacts according to OHP-14 was 22.5%. OHIP-14 consists of 14 items covering seven domains. A three-dimensional structure was used to test the existence of separate dimensions: functional limitation, pain discomfort, and psychosocial impact. A significant difference was found between males and females in the first dimension (P = 0.038) and the third dimension (P = 0.022). In addition, a significant difference was also found between the two age groups included in the study within the third dimension (P = 0.025). Conclusion: Fixed orthodontic appliances had an evident impact on OHRQoL. However, males had significantly altered functional limitations while females had a higher psychological impact. Furthermore, adults had a significantly higher psychological impact than adolescents.
