The evaluation of the incidence of malocclusions is the first step to assess the demand for orthodontic treatment in a given population, to plan prophylactic activities, to set priorities for early treatment, and to determine the efficacy and effectiveness of therapeutic activities to be introduced. <b>Aim.</b> To assess malocclusions in primary school students at the age of 10–12 years in Lublin. The epidemiological study was aimed to assess the presence of dental abnormalities, but without complete specialised orthodontic diagnostics. <b>Material and methods.</b> The study group included 242 children at the age of 10–12 years, namely 118 girls and 124 boys who were students at randomly selected primary schools in Lublin. A clinical examination of the masticatory organ was conducted in school dental offices. <b>Results.</b> Normal occlusion was observed in 15.3% of children in the study group. Malocclusions ranging from mild to severe were observed in 84.7% of subjects. Class I malocclusion was diagnosed in 57% of the study group, class II – in 24.3%, and class III – in 3.3%. In a group of 10–12-year-old children the most common orthodontic abnormality included increased overbite that was observed in 52.1% of subjects, followed by crowding of lower incisors diagnosed in 45.9% of subjects. <b>Conclusions.</b> Among 10-12-year-old students of Lublin schools malocclusions were observed in the significant majority of children. Class I and class II malocclusions were predominant therapeutic needs in a group of 10-12-year-old children according to studies conducted. With regard to class I malocclusions the most frequently diagnosed abnormalities requiring orthodontic treatment included: increased overbite, crowding of lower incisors and transverse abnormalities. <b>(Świrski A, Olszewska K, Mielnik-Błaszczak M, Owczarek K. evaluation of the incidence of malocclusions among school-age children in Lublin.

Aims This study aims to find the prevalence of orthodontic treatment need and malocclusion problems in 8–9-year-old schoolchildren in the south of Thailand. Materials and Methods A number of 202 children (100 boys and 102 girls) samples were randomly selected from all schools in Hat Yai District, Songkhla Province, Thailand. A cross-sectional survey of dental health component (DHC) of the Index of Orthodontic Treatment Need (IOTN) and malocclusion problems was investigated by clinical examination and dental model. Results Levels 4 and 5 of orthodontic treatment need according to DHC of IOTN of the sample were presented in 18.8% and 1.49%, respectively. Children who need orthodontic treatment (Grade 2–4) showed more than one highest DHC problem that indicated the level of treatment need (39.68%). Normal occlusion was found at 6.43%. Malocclusions such as Class I, Class II division 1, Class II division 2, and Class III malocclusion were observed in 78.71%, 7.92%, 3.47%, and 3.47%, respectively. Reversed overjet and overjet >9 mm were detected in 5.64% and 1.58%, respectively. Approximately half of the children (46.67%) had overbite >3.5 mm. Conclusions High percentage of children in mixed dentition period who need orthodontic treatment was found in this study. Some children who presented with the orthodontic treatment need Grade 2–4 had more than one DHC problem which identified the grade of treatment need. Class I malocclusion was most frequently found in this group of children.

Abstract Background The study aimed to investigate the association between content-based problematic smartphone use and obesity in school-age children and adolescents, including variations in the association by educational stage and sex. Methods Two-stage non-probability sampling was used to recruit 8419 participants from nineteen primary schools, five middle schools, and thirteen high schools in Shanghai in December 2017. Obesity was identified by body mass index (BMI), which was obtained from the school physical examination record, while problematic smartphone use was measured by the Revised Problematic Smartphone Use Classification Scale as the independent variable. Results The rates of obesity varied with educational stages, while problematic smartphone use increased with educational stages. Male students reported higher obesity rates (37.1%vs19.4%, P < 0.001) and greater problematic smartphone use scores (25.65 ± 10.37 vs 22.88 ± 8.94, P < 0.001) than female students. Problematic smartphone use for entertainment (smartphone users addicted to entertainment games, music, videos, novels and other applications) was positively associated to obesity status for primary school [odds ratio (OR), 1.030; 95% confidence interval (95% CI), 1.005–1.057] and high school students (OR, 1.031; 95% CI, 1.004–1.059). For female students, problematic smartphone use for entertainment was positively associated with obesity status (OR, 1.046; 95% CI, 1.018–1.075). Conclusions Problematic smartphone use may be associated with obesity in children and adolescents. The association differed based on the educational stage and sex, and the difference possessed dimensional specificity.

Transient Evoked Otoacoustic Emissions

AbstractIntroduction:The characteristics of otoacoustic emissions that make them ideally suited for universal newborn hearing loss screening could potentially be useful for the screening of older children. This study was performed in order to assess the role of otoacoustic emissions in a screening programme for middle-ear disorders and hearing loss in school-age children.Methods:Cross-sectional, preliminary screening study.Setting:Primary schools of Argolida municipality, south-east Greece, between December 2004 and March 2005.Patient selection and recruitment:All the primary school students of Argolida were invited, by press releases and individually by their teachers, to attend a session of otological and audiological screening.Results:One hundred and ninety-six children were evaluated using transient evoked otoacoustic emissions. Twenty per cent failed in both ears, while in 32 per cent otoacoustic emissions could not be produced in at least one ear. Younger children had higher rates of absent transient evoked otoacoustic emissions. The absence of otoacoustic emissions was highly correlated with tympanic membrane changes seen on otoscopy and the presence of a type B tympanogram. As a single screening modality, otoacoustic emissions had a 100 per cent sensitivity in diagnosing hearing loss worse than 30 dB, and a 90 per cent sensitivity and 64 per cent specificity in diagnosing hearing loss worse than 25 dB, which did not improve by adding tympanometry to the screening protocol.Conclusion:These results strongly suggest the potential usefulness of otoacoustic emission testing in screening school-age children for hearing loss. Further studies, taking into account cost-effectiveness issues, are indicated.

ABSTRACT Background Prevalence of malocclusion varies in different parts of a diverse country like India. Aims To determine the prevalence of malocclusion in population of Jaipur city, Rajasthan, India, as well as subjects views regarding the most important factor for seeking orthodontic treatment by patients who have malocclusion. Materials and methods The sample consisted of 700 subjects (373 males and 327 females) with age group of 15 to 30 years. Subjects were randomly selected and none of them had received orthodontic treatment previously. The subjects who showed bilateral Angle's class I molar relationship with acceptable overjet, overbite and well-aligned arches or minimal crowding were considered to have normal occlusion. The subjects with malocclusion were classified into four groups according to Angle's classification, i.e. class I, class II division 1, class II division 2 and class III malocclusions. Results About 74.57% of population was found to have malocclusion. Among these subjects, 52.57% subjects were diagnosed with class I malocclusion, 12.57% with class II division 1 malocclusion, 8% with class II division 2 and remaining 1.42% had class III malocclusion. No statistically significant differences were found between male and female subjects. Conclusion Among class I malocclusion characteristics, Angle's class I type 1 malocclusion was statistically significantly found to be the most prevalent type of malocclusion. As far as the most important factor for seeking orthodontic treatment was determined, a desire of enhancing facial appearance followed by a desire of attaining straight teeth was considered to be the chief motivational factor among this population.

Abstract Objective: To evaluate the condylar and ramal mandibular asymmetry in a group of patients with Class II subdivision malocclusion to identify possible gender differences between male and female subjects. Materials and Methods: Mandibular asymmetry measurements (condylar, ramal, and condylar-plus-ramal asymmetry values) were performed on the panoramic radiographs of 80 subjects (34 male and 46 female). The study group consisted of 40 Class II subdivision patients (18 male and 22 female; mean age 14.53 ± 3.14 years). The control group consisted of 40 subjects with normal occlusion (16 male and 24 female; mean age 14.43 ± 3.05 years). The Kruskal-Wallis test was used to determine the possible statistically significant differences between the groups for condylar, ramal, and condylar-plus-ramal asymmetry index measurements. Identified differences between groups were further analyzed using the Mann-Whitney U-test at the 95% confidence interval (P &lt; .05). Results: No gender-related difference was found for any of the asymmetry indices. Comparison of condylar, ramal, and condylar-plus-ramal asymmetry index values and gonial angle measurements for Class I and Class II sides in the Class II subdivision group and for right and left sides in the Class I group showed no statistically significant differences. However, the Class II subdivision group has longer values for condylar, ramal, and condylar-plus-ramal height measurements and only these differences were statistically significant (P &lt; .001). Conclusions: Except for condylar ramal and condylar-plus-ramal height measurements, Class II subdivision patients have symmetrical condyles when compared to normal occlusion samples according to Habbet's mandibular asymmetry indices.

The article discloses the problem of dyslalia treatment in primary school-age children. It highlights the scientific views of Ukrainian and foreign scientists concerning the diagnosis of dyslalia as a speech disorder. In particular, the author investigates various approaches to the classification of dyslalia in domestic and foreign literature and reveals the methodological foundations of dyslalia correction in the context of the formation of speech competence of primary school-age children of the New Ukrainian School.The study characterizes primary forms and types of dyslalia depending on the causes of its occurrence and the number of groups of disturbing sounds. Following the stages of speech therapy, the author describes a method for correcting violations of sound pronunciation and the formation of skills for accurate reproduction of sounds within children of primary school age.Particular attention is focused on the timely detection and correction of dyslalia in elementary school students to prevent the manifestation of violation processes in reading and writing, problems with communication in society, and the formation of the personality as a whole. The need to improve the competence of teachers, including primary school teachers working with children of this category, is noted in connection with the transition of primary schools to the new State Standard and the active introduction of inclusive education.The author substantiates the expediency of close cooperation of all participants in the educational process regarding the awareness of the shared responsibility for the child’s speech development

The present study examined age differences in time-based prospective memory (TBPM) in primary school age children and tested the role of self-initiated memory retrieval and strategic time monitoring (TM) as possible developmental mechanisms. Fifty-four children were recruited from local primary schools (27 younger children, mean age = 7.2 ± 0.55 years, and 27 older children, mean age = 9.61 ± 0.71 years). The task was a driving game scenario in which children had to drive a vehicle (ongoing task) and to remember to refuel before the vehicle runs out of gas (TBPM task, i.e., the fuel gauge served as child-appropriate time equivalent). Fuel gauge was either displayed permanently (low level of self-initiation) or could only be viewed on demand by hitting a button (high level of self-initiation). The results revealed age-dependent TBPM differences with better performance in older children. In contrast, level of self-initiated memory retrieval did not affect TBPM performance. However, strategies of TM influenced TBPM, as more frequent time checking was related to better performance. Patterns of time checking frequency differed according to children’s age and course of the game, suggesting difficulties in maintaining initial strategic TM in younger children. Taken together, the study revealed ongoing development of TBPM across primary school age. Observed age differences seemed to be associated with the ability to maintain strategic monitoring.

Introduction: Autism spectrum disorder (ASD) is a group of neurodevelopmental disorders diagnosed by impairments in social interaction and communication with repetitive and restrictive stereotyped behavioral patterns. The Prevalence of autism has been reported to be increased in recent years. This study aimed to assess the prevalence of different types of malocclusion among ASD patients in Isfahan in 2018. Materials & Methods: In a descriptive and cross-sectional trial, 92 ASD patients were studied in the age range of 7-18 years at the center for autism patients in Isfahan. Clinical oral examinations of patients are taken to assess the involved malocclusions (Cl I, Cl II and Cl III malocclusions) and malocclusion traits (deep bite, open bite and cross bite) by an educated dental student under the supervision of an orthodontist under natural light. The data are reported using frequency and percentage indices. Results: Class I malocclusion had the highest prevalence 54.3% (50) among ASD patients and the prevalence of class II and class III were found to be 19.6% (18) and 7.6% (7) respectively. The frequency of malocclusions traits of deep bite, cross bite and the open bite were 27.2% (25), 18.5% (17) and 7.6% (7) respectively. Among of the total patients, 65.2% (60) showed normal bite and 18/5% (17) showed Normal occlusion. Conclusion: ASD patients showed class I, class II and class III malocclusions from the most to least frequency and the most frequent malocclusion traits were also deep bite, cross bite and open bite respectively.
