CHILDREN (BASEL, SWITZERLAND) 2024; 11:182. [PMID: 38397294 PMCID: PMC10887506 DOI: 10.3390/children11020182] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Revised: 01/26/2024] [Accepted: 01/27/2024] [Indexed: 02/25/2024]
Abstract
(1) Introduction. An analysis was made of posterior crossbites in deciduous dentition and their relation to the type of feeding received by the child, with the objective of determining the influence of the way in which the child is fed in the early stages of life on the development of posterior crossbites. (2) Material and methods. A total of 1401 preschool children between 3 and 6 years of age from Seville (Spain) were included in the study. An intraoral exploration was carried out to assess the presence of crossbites (uni- or bilateral, and functional or not). The study was completed with a parent or legal guardian questionnaire exploring the type of feeding received by the child in the first stages of life, as well as the presence of bad oral habits and their duration. (3) Results. A total of 276 children (19.7%) presented posterior crossbite in occlusion. Uponn centering the midlines, 197 were maintained, indicating that 79 were due to premature contacts (functional crossbites). There were no significant differences in crossbites among the children who had received breastfeeding, though bottle-feeding was seen to favor crossbite. (4) Conclusions. No statistically significant relationship was found between posterior crossbites and breastfeeding, though an association between posterior crossbites and bottle-feeding was observed, with the number of crossbites increasing with the duration of bottle-feeding.

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
Objectives To determine the prevalence of primary dentition malocclusion and its linked risk indicators among a group of Saudi preschool children. Methods A cross-sectional study was carried out on preschool children aged 3 to 5 years residing in Riyadh City, the capital of Saudi Arabia. The study sample included 709 Saudi children of both genders with complete primary dentition. Oral examination was conducted for children to assess the anteroposterior, transverse, and vertical dimensions, arch spacings, and oral habits. Results The prevalence of malocclusion was 59.1% among the study participants. A deep overbite and increased overjet were found in 26.23 % and 25.11%, respectively. Arch space problems were reported, including missing primate spaces in 24.12%, missing developmental spacing in 27.93%, and crowding in 14.1%. An association between mothers aged 25 years and younger at childbirth was linked with their child's malocclusion in the primary dentition (p-value of 0.03). Conclusion The prevalence of primary dentition malocclusion among a specific group of Saudi preschool children was significantly high. Increased overbite and overjet were the most prevalent occlusal discrepancies, followed by arch spacing problems. The younger mother's age at childbirth is significantly associated with her child's malocclusion. The study results can serve as a baseline for future investigations.

Int Orthod 2023; 21:100816. [PMID: 37832339 DOI: 10.1016/j.ortho.2023.100816] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2023] [Revised: 09/16/2023] [Accepted: 09/17/2023] [Indexed: 10/15/2023]
Abstract
OBJECTIVE This systematic review and meta-analysis aimed to assess the effect of premature loss of primary teeth in children of mixed dentition age on the prevalence of malocclusion in permanent dentition. MATERIAL AND METHODS A search was conducted in Medline through PubMed, Cochrane databases, Google Scholar, and Directory of Open Access Journals (DOAJ) through March 2023. All observational studies that evaluated the association between premature loss of primary teeth and malocclusion in permanent dentition were included for analysis. Quality of studies was evaluated using the Newcastle-Ottawa tool. Meta-analysis was conducted using Cochrane Review Manager (RevMan) Version 5.3. The association between different categories of malocclusion and premature loss of primary teeth was assessed using a random-effects model. Heterogeneity was explored through sensitivity analysis. Certainty of evidence was evaluated using GRADE analysis. RESULTS This meta-analysis showed that the premature loss of primary teeth significantly increases the prevalence of overall malocclusion in permanent dentition (OR=2.54, P=0.003; I2: 83%). Subgroup analysis showed an insignificant relationship of premature loss of primary teeth with Class I malocclusion (OR=1.14, P=0.45; I2: 63%) and Class II malocclusion (OR=1.63, P=0.18; I2: 87%) but statistically significant relationship with Class III malocclusion (OR=3.73, P=0.006; I2: 71%). Sensitivity analysis reflected a significant reduction in I2 values. CONCLUSION This meta-analysis provides substantial evidence supporting the relationship between premature loss of primary teeth and malocclusion in permanent dentition. Notably, Class III malocclusions exhibited a significant association with premature loss of primary teeth.

[PMID: 38007421 PMCID: PMC10676611 DOI: 10.1186/s12903-023-03572-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Accepted: 10/23/2023] [Indexed: 11/27/2023] Open
Abstract
BACKGROUND A study is made of posterior crossbite in deciduous dentition and its possible association to extrinsic factors (bad oral habits). METHODS A total of 1168 Spanish children between 3 and 6 years of age were included in the study. Exploration of the oral cavity was performed to assess the presence of crossbite (uni- or bilateral and/or functional), and a questionnaire was administered to the parents or caregivers to determine the presence of bad oral habits and their duration. RESULTS In occlusion, 19.7% of the cases (n = 230) presented uni- or bilateral posterior crossbite. On adopting centric relation confronting the midlines, crossbite persisted in 165 children, indicating that 65 cases were due to premature contacts (functional crossbite). The identified favoring factors were pacifier use, thumb sucking, oral breathing and tongue thrusting or immature swallowing. DISCUSSION Most studies in the literature report a relationship between posterior crossbite and bad oral habits. The proportion of posterior crossbites identified in our study (16.6%) is consistent with the data published by authors such as Kobayashi, Limeira or Paolantonio, among others, but differs from the results of Zhifei Zhou, Peres or Germa. In coincidence with most studies, we recorded a statistically significant association between posterior crossbite and bad oral habits. CONCLUSIONS Bad oral habits favor the appearance of posterior crossbite, and the duration of the habit, its intensity (in the case of thumb sucking) and type (in the case of pacifier use) act as influencing factors. Functional study characterized the types of posterior crossbites and identified those attributable to premature contacts. This aspect has not been addressed by previous studies, and we consider the findings to be very interesting for analyzing and identifying the features of true crossbites.

Abstract
BACKGROUND Malocclusion is a multifactorial condition associated with genetic and environmental factors. The purpose of this study was to investigate the prevalence of occlusal traits, oral habits, and nose and throat conditions by age and to assess the association between malocclusion and its environmental factors in Japanese preschool children. METHODS A total of 503 Japanese children (258 boys and 245 girls aged 3-6 years) were recruited. Occlusal traits were assessed visually to record sagittal, vertical, and transverse malocclusion, and space discrepancies. Lip seal was recorded by an examiner, and oral habits (finger sucking, lip sucking or lip biting, nail biting, chin resting on a hand) and nose and throat conditions (tendency for nasal obstruction, allergic rhinitis, palatine tonsil hypertrophy) were assessed by a questionnaire completed by the parents. The prevalence of each item was calculated, and binary logistic regression was used to examine the factors related to malocclusion. RESULTS 62.0% of preschool children in the present study exhibited malocclusion, and 27.8% exhibited incompetent lip seal. Nail biting was the most frequent oral habit with a prevalence of 18.9%. Nasal obstruction was recorded in 30.4% of children. The results of binary logistic regression showed that incompetent lip seal was significantly related to malocclusion, and that nail biting was significantly negatively related. CONCLUSIONS Incompetent lip seal is significantly associated with malocclusion, but nail biting may not necessarily be a deleterious habit for the occlusion in Japanese preschool children.

Abstract
This survey examined the prevalence of malocclusion and its associated factors in 3- to 5-year-old children in Huizhou, China. Children were recruited from 21 kindergartens using a multistage sampling method. Two examiners performed oral examinations on the children, assessing occlusal traits, including primary molar and canine relationship, overjet, crossbite, overbite, anterior open bite, scissor bite, midline deviation, crowding, and spacing. Caries experience was recorded. Self-administered questionnaires were distributed to collect background information and oral health-related habits. Chi-square test, Mann-Whitney U test, and binary logistic regression were conducted. The study invited 1485 children and eventually recruited 1454 (52.9% boys; response rate: 97.9%). The prevalence of malocclusion was 68.3%, and deep overbite was found in 48.6% of the children. Children who had lip-biting habits had a higher prevalence of deep overbite than those who did not (OR = 2.36, p < 0.05). Children who had digit-sucking habits and dental caries in anterior maxillary teeth had a lower prevalence of deep overbite than those who did not (OR = 0.73 and 0.70, respectively, p < 0.05). In conclusion, over half of the children in Huizhou who participated in the study had malocclusion. Dental caries in anterior maxillary teeth, digit-sucking, and lip-biting were the associated factors of deep overbite.

Abstract
Anterior open bite (AOB) is the insufficient vertical overlapping between the maxillary and mandibular anteriors when the teeth are in centric occlusion. The purpose of this study was to determine the prevalence of AOB in children and adolescents who visited a private dental hospital. In this study, subjects aged between 16 and 18 years with AOB were included. Data about orthodontic examination of patients were taken from preentered dental records of the hospital. Data of patients with AOB regarding age, gender, and intraoral and extraoral features were collected from the case records of the subjects, and statistical analysis was performed (Chi-square test and nonparametric correlations). The prevalence percentage of open bite in the anteriors was 2.7%, with more prevalence in Class 1 subjects (81.5%). Subjects with AOB had competent lips (81.8%), straight nasolabial angle (86.8%), and shallow palatal vault (49.5%). AOB had no significant relationship with the type of malocclusion, palatal vault, and lip competency, according to the Chi-square test. AOB and the nasolabial angle had a significant association. Both acute and right-angled nasolabial angles were commonly seen in adolescent patients with AOB. In children and adolescents visiting a private dental hospital in Chennai, the prevalence of AOB was found to be 2.7%. A significant association was observed between AOB and nasolabial angle.

Abstract
BACKGROUND In school dental screening, a dental health professional visually inspects children's oral cavities in a school setting and provides information for parents on their child's current oral health status and treatment needs. Screening at school aims to identify potential problems before symptomatic disease presentation, hence prompting preventive and therapeutic oral health care for the children. This review evaluates the effectiveness of school dental screening for improving oral health status. It is the second update of a review originally published in December 2017 and first updated in August 2019. OBJECTIVES To assess the effectiveness of school dental screening programmes on overall oral health status and use of dental services. SEARCH METHODS An information specialist searched four bibliographic databases up to 15 October 2021 and used additional search methods to identify published, unpublished and ongoing studies. SELECTION CRITERIA We included randomised controlled trials (RCTs; cluster- or individually randomised) that evaluated school dental screening compared with no intervention, or that compared two different types of screening. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. MAIN RESULTS The previous version of this review included seven RCTs, and our updated search identified one additional trial. Therefore, this update included eight trials (six cluster-RCTs) with 21,290 children aged 4 to 15 years. Four trials were conducted in the UK, two in India, one in the USA and one in Saudi Arabia. We rated two trials at low risk of bias, three at high risk of bias and three at unclear risk of bias. No trials had long-term follow-up to ascertain the lasting effects of school dental screening. The trials assessed outcomes at 3 to 11 months of follow-up. No trials reported the proportion of children with treated or untreated oral diseases other than caries. Neither did they report on cost-effectiveness or adverse events. Four trials evaluated traditional screening versus no screening. We performed a meta-analysis for the outcome 'dental attendance' and found an inconclusive result with high heterogeneity. The heterogeneity was partly due to study design (three cluster-RCTs and one individually randomised trial). Due to this inconsistency, and unclear risk of bias, we downgraded the evidence to very low certainty, and we are unable to draw conclusions about this comparison. Two cluster-RCTs (both four-arm trials) evaluated criteria-based screening versus no screening, suggesting a possible small benefit (pooled risk ratio (RR) 1.07, 95% confidence interval (CI) 0.99 to 1.16; low-certainty evidence). There was no evidence of a difference when comparing criteria-based screening to traditional screening (RR 1.01, 95% CI 0.94 to 1.08; very low-certainty evidence). One trial compared a specific (personalised) referral letter to a non-specific letter. Results favoured the specific referral letter for increasing attendance at general dentist services (RR 1.39, 95% CI 1.09 to 1.77; very low-certainty evidence) and attendance at specialist orthodontist services (RR 1.90, 95% CI 1.18 to 3.06; very low-certainty evidence). One trial compared screening supplemented with motivation to screening alone. Dental attendance was more likely after screening supplemented with motivation (RR 3.08, 95% CI 2.57 to 3.71; very low-certainty evidence). One trial compared referral to a specific dental treatment facility with advice to attend a dentist. There was no evidence of a difference in dental attendance between these two referrals (RR 0.91, 95% CI 0.34 to 2.47; very low-certainty evidence). Only one trial reported the proportion of children with treated dental caries. This trial evaluated a post-screening referral letter based on the common-sense model of self-regulation (a theoretical framework that explains how people understand and respond to threats to their health), with or without a dental information guide, compared to a standard referral letter. The findings were inconclusive. Due to high risk of bias, indirectness and imprecision, we assessed the evidence as very low certainty. AUTHORS' CONCLUSIONS The evidence is insufficient to draw conclusions about whether there is a role for school dental screening in improving dental attendance. We are uncertain whether traditional screening is better than no screening (very low-certainty evidence). Criteria-based screening may improve dental attendance when compared to no screening (low-certainty evidence). However, when compared to traditional screening, there is no evidence of a difference in dental attendance (very low-certainty evidence). For children requiring treatment, personalised or specific referral letters may improve dental attendance when compared to non-specific referral letters (very low-certainty evidence). Screening supplemented with motivation (oral health education and offer of free treatment) may improve dental attendance in comparison to screening alone (very low-certainty evidence). We are uncertain whether a referral letter based on the 'common-sense model of self-regulation' is better than a standard referral letter (very low-certainty evidence) or whether specific referral to a dental treatment facility is better than a generic advice letter to visit the dentist (very low-certainty evidence). The trials included in this review evaluated effects of school dental screening in the short term. None of them evaluated its effectiveness for improving oral health or addressed possible adverse effects or costs.

Sasaki Y, Otsugu M, Sasaki H, Fujikawa N, Okawa R, Kato T, Nakano K. Relationship between Dental Occlusion and Maximum Tongue Pressure in Preschool Children Aged 4-6 Years. CHILDREN (BASEL, SWITZERLAND) 2022; 9:141. [PMID: 35204862 PMCID: PMC8870039 DOI: 10.3390/children9020141] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Revised: 01/18/2022] [Accepted: 01/19/2022] [Indexed: 06/14/2023]
Abstract
Tongue function is regarded as a primary factor in the etiology of malocclusion, but details of the relationship remain unknown. The purpose of the present study was to investigate maximum tongue pressure, in preschool children to examine its relationship with dental occlusion. A total of 477 healthy children (248 boys, 229 girls, aged 4-6 years) were recruited. Dental occlusion was assessed visually to record sagittal, vertical, and transverse malocclusion, and space discrepancies. Maximum tongue pressure was measured using a balloon-based tongue pressure measurement device. Additionally, 72 children (37 boys, 35 girls, aged 4-5 years) were recruited for a 1-year follow-up study. Approximately half of the children (53.5%) showed some type of malocclusion in the present study. Maximum tongue pressure was highest in the 6-year-old children. The results of a two-way ANCOVA show that the effect of age was significant (p < 0.001); however, the effects of sex and dental occlusion, or the interactions among these variables, did not reach significance. Additionally, maximum tongue pressure increased significantly in the 1-year follow-up study (p < 0.001), especially in the normal occlusion group. Maximum tongue pressure increases markedly with growth in the preschool years and can be associated with some types of malocclusion in preschool children.

Abstract
OBJECTIVE The aim of this study was to determine the relationship of malocclusion with the presence and severity of temporomandibular disorders (TMDs) in children. MATERIALS AND METHODS A clinical examination was performed in 87 patients (from 4 to 14 years of age) who attended the dentistry clinics of Universidad del Valle. RESULTS The 77 patients studied had malocclusions; 55 patients had TMD and 67.3% were female. The most frequent symptom of TMD was articular unilateral noise with 33.8%, followed by pain in at least one masticatory muscle with 26%. TMJ pain was observed in 24.7% of the patients. There was a statistically significant relationship between the presence and severity of TMD with type of dentition and transverse malocclusion, respectively. CONCLUSION The presence of TMD in children with malocclusion presented in a high frequency. TMD depends on the type of dentition and its severity is dependent on transverse malocclusion.

Abstract
BACKGROUND Malocclusion affects the chewing, dental aesthetics, jaw development, and overall attractiveness of individuals. The negative impact of malocclusion is high, particularly in adolescents who can be the target of teasing, intimidation, and name-calling. Even if, malocclusion is a common problem in developing countries, there was a paucity of data in Ethiopia. Therefore, this study aimed to determine the prevalence and associated factors of malocclusion in northwest Ethiopia. METHODS This cross-sectional study was done at the University of Gondar comprehensive hospital from December 1, 2019, to October 30, 2020. Four hundred seventy-six study participants were selected using a systematic random sampling method. Data collection was done using a structured interviewer-administered questionnaire. Qualified dental professionals examined malocclusion traits according to the WHO oral health survey tool and evaluated for the presence of malocclusion in terms of angles classification, open bite, crossbite, spacing, and crowding. Data entry was done using Epi-Info 7, and analyzed by SPSS 26. Descriptive statistics and logistic regression was done to analyze the data. RESULTS A total of 476 subjects were included in the study with a mean age of 29.83 (SD±14.013). The prevalence of malocclusion was 55.9% (95% CI: 51.39-60.28). The common occlusal traits were class-I malocclusion with minor discrepancy (34.9%), anterior crowding (22.9%), and anterior open bite (21.6%). The prevalence of anterior crossbite, posterior crossbite, class-II, and class-III malocclusion was 5.9%, 3.8%, 10.9%, and 8.0%, respectively. Males (AOR=1.6, 95% CI: 1.11, 2.30), urban residents (AOR=1.64, 95% CI: 1.06, 2.56), monthly income of ≤2500 Ethiopian Birr (AOR=1.27, 95% CI: 1.02, 1.59) and mouth breathers (AOR=2.50, 95% CI: 1.72, 2.63) were significantly associated with malocclusion. CONCLUSION Significant amount of the study participants had malocclusion. Males, urban residents, low monthly income, and mouth breathing habits were independent factors for a malocclusion. Therefore, early attention to the development of the dentition and occlusion, and necessary functional correction during childhood are important to reduce its prevalence and lifelong adverse effect. Moreover, publicly financed orthodontic treatment should be scheduled, and supplied to individuals in desperate need of orthodontic care.

The Dental Aesthetic Index and Its Association with Dental Caries, Dental Plaque and Socio-Demographic Variables in Schoolchildren Aged 12 and 15 Years. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18189741. [PMID: 34574666 PMCID: PMC8468568 DOI: 10.3390/ijerph18189741] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 07/22/2021] [Revised: 09/01/2021] [Accepted: 09/09/2021] [Indexed: 11/17/2022]
Abstract
The Dental Aesthetic Index (DAI) was determined in 12- and 15-year-old schoolchildren to ascertain the prevalence of malocclusion and to assess its association with dental caries experience, dental plaque accumulation, and socio-demographic variables. We performed a cross-sectional study with a stratified two-stage sampling design. An oral health survey and oral examination were conducted, and socio-demographic data were recorded. The sample comprised 1453 schoolchildren aged 12 (868) and 15 (585). These two samples were analyzed separately because statistically significant differences were found: the 12-year-old age group displayed a higher frequency of schoolchildren who attended state-run public schools (p = 0.004) and belonged to a lower social class (p = 0.001); the 15-year-old age group registered higher levels of caries (p = 0.001) and lower levels of dental plaque (p < 0.001). The malocclusion was 9.5% higher (p = 0.001), and the global mean DAI score was likewise higher among the 12-year-olds (p < 0.001). The multivariate regression analysis not only showed that caries and dental plaque were the variables that were the most strongly associated with malocclusion, but that caries (OR = 1.5) and dental plaque (OR > 2) were also risk factors for malocclusion in both groups. In conclusion, this study revealed a higher prevalence of malocclusion and dental plaque at age 12. A higher risk of caries and dental plaque was found to be related to the presence of malocclusion in both age groups.

Abstract
INTRODUCTION The objectives of this study were to determine the prevalence of malocclusion among children with Zika virus-associated microcephaly (MZV) and to describe the most common malocclusion in this population. METHODS This was a cross-sectional study including patients aged between 30 and 36 months diagnosed with MZV. Healthy children were randomly selected with the same sociodemographic characteristics as the control group. Information about arch-type, primate spaces, arch form, overbite, overjet, midline deviation, anterior crossbite, anterior open bite, and the posterior crossbite was recorded. The statistical analysis used descriptive analysis, Pearson chi-square test, and multivariate logistic regression. RESULTS Forty children comprised the MZV group, and 40 comprised the control group. Our results demonstrated a significantly higher prevalence of malocclusions in children who had MZV than the control group (P <0.001). Patients with MZV were more likely to have late eruption (P <0.001), hypoplastic maxillary arch (P <0.001), hypoplastic mandibular arch (P <0.001), excessive overjet (P <0.001), and posterior crossbite (P = 0.004). CONCLUSIONS The prevalence of malocclusion was higher among children with MZV. Late eruption, hypoplastic maxillary arch, hypoplastic mandibular arch, excessive overjet, and posterior crossbite were the most common characteristics for this population.

Abstract
Background and Objective: This study analyzes the possibility that Stomatognathic and Postural systems are related by muscle chains. Malocclusion may influence the posture, contact between the foot and the ground, center of mass, footprint or vice-versa. This study aimed to verify whether there is a relationship between dental occlusion and podal system. Materials and Methods: A cross-cutting, descriptive study was carried out on 409 children (222 boys and 187 girls) between 8 and 14 years old. Dental occlusion was assessed on the sagittal plane (Angle's classification) the contact between the foot and the ground and the center of mass were evaluated using a stabilometric platform. Results: There was a statistically significant relationship between the plantigrade phase, the contact surface area and center of gravity. There was a prevalence of molar and canine Angle's class II malocclusion. In molar class II, an anterior center of gravity was predominant, in class I it was centered and in class III, it was posterior. There was significant correlation between malocclusions and the FPI (foot posture index) of the left foot and the height of the scaphoid in the right foot (P < 0.001). Conclusions: Some authors agree with our results. There is still much uncertainty in terms of showing a relationship between both systems. In addition, there is scarce scientific evidence on the topic. Some kind of relationship between the two systems has been proven. Studies that evaluate a group of subjects in a longitudinal manner are necessary to enable the changes taking place in both systems to be defined.

Abstract
PURPOSE To evaluate the correlation between spacing in the primary dentition and caries experience. METHODS One hundred seventy-four clinical records, including photographs during 2017-2019 were assessed for primate, generalised and interdental spaces. The mean of decayed, missing or filled teeth and surfaces (dmft and dmfs) were recorded to quantify the caries experience. Linear regression analyses were used to ascertain correlations between spacing and dental caries. The strength of the associations was quantified using odds ratio (OR) and 95% confidence interval (CI). RESULTS Ninety-seven boys and 77 girls were included in the final analysis. Approximately 41% of children had primate space in all four quadrants, and 15% of children had no primate spaces in all four quadrants. 50% of children did not exhibit generalised spacing, while 39% of children showed interdental spacing. Children with no primate space had approximately five surfaces higher dmfs score compared to those with primate space in all four quadrants (95% CI - 9.27 to - 1.23; p < 0.05). Similarly, children with no primate space in the mandible had 6.12 surfaces higher dmfs score compared to those with primate space in the mandibular arch (95% CI - 10.07 to - 2.17; p < 0.05). CONCLUSIONS Preschool children with no primate space exhibited a 50% increase in dmfs scores compared to children with primate space.

Abstract
Anterior open bite (AOB) is related to functional alterations of the stomatognathic system. There are no studies concerning brain activation of the cortex comparing children with and without AOB during rest and activities such as deglutition and phonation. The aim of this study was to determine the activity of the brain cortex of children with AOB at rest and during phonation and deglutition and to evaluate the association of intelligence quotient (IQ), attention (Test of Variables of Attention, known as TOVA), beats per minute (BPM), and oxygen saturation measurement (SpO2) with brain activity in subjects with AOB. Fourteen children (seven with AOB and seven without AOB) with mixed dentition, aged 10–13 years, underwent an IQ test, TOVA, SpO2, and quantitative electroencephalography (QEEG). Electrodes were set in the scalp, according to the 10–20 protocol. Data were analyzed using statistical tests to assess comparisons between children with and without AOB. The results showed that IQ, TOVA, SpO2, or BPM did not show any statistically significant differences between the groups, except for the response time (contained in TOVA) (p = 0.03). Significant differences were found for the brain activity during rest (Condition 1) of the tongue, between children with and without AOB (p < 0.05 for alpha/theta and alpha peaks), whereas there were no differences during function (Condition 2). The findings of this investigation provide insights about the cortex activity of the brain while the tongue is in the resting position in children with AOB. This may imply an altered activity of the brain cortex, which should be considered when diagnosing and treating AOB. Other diagnostic techniques derived from investigations based on neuroscience could develop new diagnostic and therapeutic techniques to give better solutions to children with malocclusions. Treatments should be focused not only on the teeth but also on the brain cortex.

Abstract
The purpose of this investigation was to show how to manage an anterior crossbite in early mixed dentition with an eruption guidance appliance (EGA). The analyzed clinical case reported an anterior crossbite, a bimaxillary retrusion tendency, and a horizontal growth pattern. The anterior crossbite was an unfavorable occlusal condition that could lead to a class III malocclusion growth pattern. An early treatment approach was suggested to reach a correct sagittal jaw relationship. Hence, the selected approach acted on the dentoalveolar sector, aiming to have effects on the posterior vertical dimension and to improve the sagittal jaw's relation. An EGA was selected to treat the patient in early mixed dentition. After 7 months of therapy with night-time use, the dental malocclusion was completely resolved. The patient continued to be treated with the same device, used as active retention. With the EGA treatment, the erupting forces, rather than the active forces, were used to resolve the dental malocclusion. This approach allowed a low compliance requirement and had a minimum psychosocial and psychological impact on the patient. The early treatment was essential to give a functional occlusion and a good balance of the soft perioral tissues and muscles.

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.

Abstract
Resumo Introdução A mordida aberta anterior é um dos tipos de má-oclusão mais frequentes em pré-escolares, sendo considerada um dos problemas oclusais mais difíceis de tratar, principalmente por sua etiologia multifatorial e sua íntima relação com hábitos bucais deletérios. Objetivo Identificar a prevalência de mordida aberta anterior nos pré-escolares de Salvador-BA, bem como fatores potencialmente associados à mesma. Material e método Trata-se de um estudo de corte transversal em 1.577 crianças em idade pré-escolar (36 a 71 meses), que frequentavam creches públicas municipais de Salvador-BA. Resultado A média de idade das crianças foi aproximadamente 54 meses. A maioria pertencia ao sexo masculino (50,29%). A população de estudo foi predominantemente composta por negros e pardos (92,02%). A prevalência de má-oclusão foi de 40,46% e, destes, 14,02% possuíam mordida aberta. Com relação à escolaridade, a maior parte das mães (55,86%) e dos pais (50,08%) foi igual ou superior ao Ensino Fundamental II Completo. A sucção digital foi comum em 6,73% das crianças e 10,39% faziam sucção de chupeta. Foram identificados, como fatores de proteção à mordida aberta, a escolaridade do pai maior ou igual ao Ensino Fundamental II completo (RP= 0,62 IC= 0,41-0,95) e a onicofagia (RP= 0,34 IC= 0,21-0,56). Como fatores de risco, identificaram-se o uso de chupeta (RP= 17,98 IC= 10,91-29,62) e a sucção digital (RP= 11,04 IC= 6,0-20,32). Conclusão Medidas educativas direcionadas aos pais e responsáveis se fazem essenciais para a prevenção do desenvolvimento de hábitos deletérios nos pré-escolares. Outros estudos são necessários a fim de aprofundar o entendimento sobre os fatores de proteção identificados neste estudo.

Abstract
Background: The parental awareness and perceptions help in early recognition of problems in deciduous dentition, which will help us plan better preventive measures. Hence, the present study was conducted to evaluate the perceptions of Saudi parents residing in Riyadh towards the problems related to primary dentition of their children. Materials and Methods: A cross-sectional study was conducted on the patients attending private dental institution in Riyadh city. Information about demographic details, questions related to maintenance of primary teeth, and future implications of poor primary dentition health were collected. Descriptive statistics and Chi-square test were used for the analysis. The level of significance was set at P < 0.05. Results: A total of 1773 male and females filled up the survey form, which comprised of 28% males and 72% females, and maximum parents (68%) were university graduates. Overall better responses were in females and parents having more children. Conclusion: Over all mothers had a higher level of knowledge and positive attitude towards their children's oral health as compared to fathers. Developing and strengthening optimistic outlook among parents towards oral health especially primary dentition is utmost important.

Abstract
OBJECTIVE We provided baseline data for oral public health through epidemiological surveys to investigate the prevalence of malocclusion and orthodontic treatment proportion in 12- to 14-year-old adolescents in Jiangxi province, China. METHODS Multi-stage random cluster sampling was used. A total of 5 387 12- to 14-year-old adolescents were examined by three professional dentists according to Angle's classification of malocclusion. The subjects were recruited from 30 secondary schools in five counties in Jiangxi Province. Results were statistically analyzed by SPSS19.0. RESULTS The prevalence of malocclusion was 79.67% among adolescents aged 12-14 years in Jiangxi province. The composition ratios of ClassⅠ, Class Ⅱ Division 1, Class Ⅱ Division 2, and Class Ⅲ malocclusion were 30.96%, 16.36%, 12.78%, and 19.13% respectively. ClassⅠmalocclusion had the highest composition ratio, and the most common clinical manifestation of malocclusion was dentition crowding with a prevalence of 91.30%. The prevalence rate of malocclusion was higher in boys than in girls at 81.16% and 78.21%, respectively (P<0.05). This condition had different prevalence rates in Nanchang, Yichun, Jiujiang, Shangrao, and Ganzhou (P<0.05) with the highest in Nanchang and lowest in Ganzhou. Malocclusion was related to caries, and its prevalence rate was higher in patients with caries than in those without caries (P<0.05). The orthodontic rate of malocclusion was 2.63%, and the value was higher for girls than that for boys (P<0.05). The rate of orthodontic in urban areas was higher than that in rural areas (P<0.05). CONCLUSIONS Compared with local and international findings on malocclusion of adolescents, high prevalence and low orthodontic rate were found in Jiangxi province. Strengthening the combination of prevention and treatment is important for the physical and mental health of adolescents. We should actively conduct oral health education, popularize the knowledge of malocclusion, and actively treat caries.

Abstract
BACKGROUND School dental screening refers to visual inspection of children's oral cavity in a school setting followed by making parents aware of their child's current oral health status and treatment needs. Screening at school intends to identify children at an earlier stage than symptomatic disease presentation, hence prompting preventive and therapeutic oral health care for the children. This review evaluates the effectiveness of school dental screening in improving oral health status. It is an update of the original review, which was first published in December 2017. OBJECTIVES To assess the effectiveness of school dental screening programmes on overall oral health status and use of dental services. SEARCH METHODS Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 4 March 2019), the Cochrane Central Register of Controlled Trials (CENTRAL, the Cochrane Register of Studies, to 4 March 2019), MEDLINE Ovid (1946 to 4 March 2019), and Embase Ovid (15 September 2016 to 4 March 2019). The US National Institutes of Health Trials Registry (ClinicalTrials.gov) and the World Health Organization International Clinical Trials Registry Platform were searched for ongoing trials. No restrictions were placed on language or publication status when searching the electronic databases; however, the search of Embase was restricted to the last six months due to the Cochrane Centralised Search Project to identify all clinical trials and add them to CENTRAL. SELECTION CRITERIA We included randomised controlled trials (RCTs) (cluster or parallel) that evaluated school dental screening compared with no intervention or with one type of screening compared with another. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. MAIN RESULTS We included seven trials (five were cluster-RCTs) with 20,192 children who were 4 to 15 years of age. Trials assessed follow-up periods of three to eight months. Four trials were conducted in the UK, two were based in India and one in the USA. We assessed two trials to be at low risk of bias, two trials to be at high risk of bias and three trials to be at unclear risk of bias.None of the trials had long-term follow-up to ascertain the lasting effects of school dental screening.None of the trials reported the proportion of children with untreated caries or other oral diseases, cost effectiveness or adverse events.Four trials evaluated traditional screening versus no screening. We performed a meta-analysis for the outcome 'dental attendance' and found an inconclusive result with high heterogeneity. The heterogeneity was found to be, in part, due to study design (three cluster-RCTs and one individual-level RCT). Due to the inconsistency, we downgraded the evidence to 'very low certainty' and are unable to draw conclusions about this comparison.Two cluster-RCTs (both four-arm trials) evaluated criteria-based screening versus no screening and showed a pooled effect estimate of RR 1.07 (95% CI 0.99 to 1.16), suggesting a possible benefit for screening (low-certainty evidence). There was no evidence of a difference when criteria-based screening was compared to traditional screening (RR 1.01, 95% CI 0.94 to 1.08) (very low-certainty evidence).In one trial, a specific (personalised) referral letter was compared to a non-specific one. Results favoured the specific referral letter with an effect estimate of RR 1.39 (95% CI 1.09 to 1.77) for attendance at general dentist services and effect estimate of RR 1.90 (95% CI 1.18 to 3.06) for attendance at specialist orthodontist services (low-certainty evidence).One trial compared screening supplemented with motivation to screening alone. Dental attendance was more likely after screening supplemented with motivation, with an effect estimate of RR 3.08 (95% CI 2.57 to 3.71) (low-certainty evidence).Only one trial reported the proportion of children with treated dental caries. This trial evaluated a post screening referral letter based on the common-sense model of self-regulation (a theoretical framework that explains how people understand and respond to threats to their health), with or without a dental information guide, compared to a standard referral letter. The findings were inconclusive. Due to high risk of bias, indirectness and imprecision, we assessed the evidence as very low certainty. AUTHORS' CONCLUSIONS The trials included in this review evaluated short-term effects of screening. We found very low-certainty evidence that is insufficient to allow us to draw conclusions about whether there is a role for traditional school dental screening in improving dental attendance. For criteria-based screening, we found low-certainty evidence that it may improve dental attendance when compared to no screening. However, when compared to traditional screening, there is no evidence of a difference in dental attendance (very low-certainty evidence).We found low-certainty evidence to conclude that personalised or specific referral letters may improve dental attendance when compared to non-specific counterparts. We also found low-certainty evidence that screening supplemented with motivation (oral health education and offer of free treatment) may improve dental attendance in comparison to screening alone. For children requiring treatment, we found very-low certainty evidence that was inconclusive regarding whether or not a referral letter based on the 'common-sense model of self-regulation' was better than a standard referral letter.We did not find any trials addressing possible adverse effects of school dental screening or evaluating its effectiveness for improving oral health.

Abstract
Background The quality of life in Class III malocclusion patients are worse than those without the disorder and previous studies have shown that surgical orthodontic treatment has a different effect on these patients compared with mild or moderate malocclusion. This study aimed to investigate the changes in quality of life in patients with Class III malocclusion during surgical orthodontic treatment in Chinese young adults. Methods The 14-item Short Form Oral Health Impact Profile (OHIP-14), and the 22-item Orthognathic Quality of Life Questionnaire (OQLQ) were used to assess the effect of surgical orthodontic treatment on the quality of life in 21 patients with Class III malocclusion at pre-treatment (T0), pre-surgical orthodontic treatment (6 to 8 months, T1) and post-surgical orthodontic treatment (6 to 8 months after surgery, T2), and 24 healthy individuals were included as controls. The comparisons in numerical variables between patients and controls were performed using Mann-Whitney U test. The scores of the two questionnaires between T0, T1, T2 and controls (Tc) were compared using generalized estimating equation. Results According to OHIP-14 questionnaire, the mean scores in T0 and T1 were higher than those in T2 and Tc (P < 0.001), and a significant decrease was observed after post-surgical orthodontic treatment (P < 0.001), which achieved a level similar to the control group (P > 0.05). As to OQLQ questionnaire, the mean scores of all domains showed a significant increase between T0 and T1 except for awareness of dentofacial aesthetics (P > 0.05) and social aspects of dentofacial deformity (P > 0.05), followed by a significant decrease between T1 and T2. Conclusion Surgical orthodontic treatment may improve quality of life in patients with Class III malocclusion, but pre-surgical orthodontic treatment may have an adverse effect on quality of life.

Abstract
Background Epidemiological data on malocclusion among Chinese children are scant. The aim of this study was to provide detailed information on the prevalence of malocclusion in early mixed dentition children in Shanghai, China. Methods A cross-sectional survey was conducted from September 2016 to April 2017, and 2,810 children aged 7- to 9- years were selected from 10 primary schools by cluster random sampling. Several occlusal parameters, including Angle molar relationship, overjet, overbite, open bite, anterior and posterior crossbite, midline displacement, scissors bite, and teeth crowding and spacing, were clinically registered by five calibrated orthodontic dentists. Results We found that 79.4% children presented one or more occlusal anomalies. Angle Class I, Class II and Class III molar relationship were recorded in 42.3%, 50.9% and 5.9% of the sample, respectively. The proportion of Class III increased from 5.0% at age 7 to 7.8% at age 9. In the sagittal plane, increased overjet >3 mm was observed in 40.8% subjects, while the prevalence of severe overjet (>8 mm), anterior edge-to-edge (zero overjet) and anterior crossbite were 5.2%, 8.1% and 10.5%, respectively. Vertically, deep overbite >2/3 overlap was found in 6.2% of the children and open bite in 4.3%. Boys exhibited a higher rate of overbite than girls. For the transversal occlusal anomalies, 36.1% of the children had a midline displacement, which was followed by posterior crossbite (2.6%) and scissors bite (1.0%). Teeth space discrepancies were also common anomalies and anterior crowding (>2 mm) affecting 28.4% of the children, while anterior spacing (>4 mm) affecting 9.5%. Girls showed a higher prevalence of anterior crowding and a lower frequency of teeth spacing than boys. Conclusions Our study demonstrated that malocclusion is prevalent among children in the early mixed dentition, and more health resources should be warranted to meet the challenge of prevention or early intervention of malocclusion.

Prevalence of malocclusion in primary dentition in mainland China, 1988-2017: a systematic review and meta-analysis. Sci Rep 2018; 8:4716. [PMID: 29549346 PMCID: PMC5856803 DOI: 10.1038/s41598-018-22900-x] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2017] [Accepted: 03/02/2018] [Indexed: 12/16/2022] Open
Abstract
Malocclusion is a common oral disease affecting children with various reported prevalence rates. This meta-analysis aimed to determine the epidemiological characteristics of malocclusion among pre-schoolers in mainland China from 1988 to 2017. A total of 31 qualified papers describing 51,100 Chinese children aged 2–7 years were selected. The pooled malocclusion prevalence was 45.50% (95% confidence interval (CI): 38.08–52.81%) with 26.50% Class I (CI: 19.96–33.12%), 7.97% Class II (CI: 6.06–9.87%) and 12.60% Class III (CI: 9.45–15.68%) cases. The most common type of malocclusion was overbite (33.66%, CI: 27.66–39.67%), and the flush terminal type (47.10%, CI: 28.76–65.44%) was the most common in the terminal plane relationship. An increasing trend and wide variations across the country were observed. Additionally, there was no significant difference in malocclusion by gender (relative risk (RR) = 1.01, [0.96–1.06]) or urban/rural area (RR = 0.99, [0.82–1.20]). Although this study represents a narrow view of deciduous-dentition malocclusion in mainland China, the results provide sample evidence that can aid clinicians and policy makers towards early prevention and timely treatment.

Dental attendance was more likely after screening supplemented with motivation, with an effect estimate of RR 3.08 (95% CI 2.57 to 3.71) (low-certainty evidence).None of the trials had long-term follow-up to ascertain the lasting effects of school dental screening.None of the trials reported cost-effectiveness and adverse events. AUTHORS' CONCLUSIONS The trials included in this review evaluated short-term effects of screening, assessing follow-up periods of three to eight months. We found very low certainty evidence that was insufficient to allow us to draw conclusions about whether there is a role for traditional school dental screening in improving dental attendance. For criteria-based screening, we found low-certainty evidence that it may improve dental attendance when compared to no screening. However, when compared to traditional screening there was no evidence of a difference in dental attendance (very low-certainty evidence).We found low-certainty evidence to conclude that personalised or specific referral letters improve dental attendance when compared to non-specific counterparts. We also found low-certainty evidence that screening supplemented with motivation (oral health education and offer of free treatment) improves dental attendance in comparison to screening alone.We did not find any trials addressing cost-effectiveness and adverse effects of school dental screening.
