Prevalence and nature of bullying in schoolchildren aged 10-14 years and its association with malocclusion: A cross-sectional study in the South East of the UK.

OBJECTIVE: To investigate the prevalence of, and relationship between, bullying and malocclusion in schoolchildren aged 10-14 years in the South East of the UK. DESIGN: Cross-sectional cohort study. SETTING: Sixteen primary and secondary schools in South East of the UK. PARTICIPANTS: Schoolchildren aged 10-14 years who were consented to participate. METHODS: The prevalence and nature of bullying were measured using a questionnaire. Traits of malocclusion and the need for orthodontic treatment were assessed by clinical examination and determined by the Index of Orthodontic Treatment Need (IOTN) Dental Health (DHC) and Aesthetic components (AC). RESULTS: Complete data were collected for 698 participants. The number defined as being bullied was 68 (9.7%). There was no difference in the prevalence of bullying between gender, ethnicity or age. Higher rates of bullying were reported in mixed sex schools (P = 0.03). Participants with an increased overjet (P = 0.02) and/or a greater need for treatment, as measured by IOTN DHC (P = 0.01) and AC (P = 0.01), reported higher rates of bullying. While there was no difference in the overall prevalence of bullying between genders, boys were more likely than girls to experience physical bullying (P <0.001) and being called names (P = 0.03). CONCLUSION: A significant relationship was evident between being bullied and certain traits of malocclusion.

Individual and contextual determinants associated with bullying in schoolchildren eight to ten years of age.

Investigate individual and contextual determinants associated with bullying in schoolchildren eight to ten years of age. A cross-sectional study was conducted with 739 schoolchildren, who answered a question about episodes of bullying related to oral health and questionnaires addressing childhood anxiety and orofacial dysfunction. The guardians provided information on sociodemographic characteristics, sleep disorders, and oral health literacy. Trained examiners assessed the children for the diagnosis of dental caries using the International Caries Detection and Assessment System, malocclusion using the Dental Aesthetic Index, orofacial dysfunction using the Nordic Orofacial Test-Screening and traumatic dental injury (Andreasen criteria) (Kappa> 0.80). The contextual variables were the type of school and the monthly income of the school neighborhood. Descriptive statistics was performed to characterize the sample and unadjusted and adjusted (p <0.05) multilevel Poisson regression models were run. The prevalence of bullying was 13.3%. After the adjusted analysis, malocclusion (PR=1.59; 95%CI:1.03-2.44) and anxiety (PR=1.79; 95%CI:1.10-2.93) remained associated with bullying. In terms of context, the monthly income of the neighborhood of the school was associated with bullying (PR=1.75; 95%CI:1.12-2.72). Malocclusion and anxiety influenced the occurrence of bullying. A lower average income in the school neighborhood was an important contextual determinant for the increase in the prevalence of bullying.

Oral Problems in Brazilian Individuals with Rare Genetic Diseases That Affect Skeletal Development.

The present study aimed to compare the prevalence of oral problems between individuals with rare genetic diseases that affect skeletal development and individuals without rare diseases. A cross-sectional study was conducted with 210 individuals between two and fifty-four years of age: 105 with rare genetic diseases (27 with mucopolysaccharidosis [MPS] and 78 with osteogenesis imperfecta [OI]) and 105 without rare diseases. The rare genetic disease group was recruited from hospital units that provide care for patients with MPS and OI in five states of Brazil, and the other group was recruited from the same location. The participants were examined with regards to malocclusion, dental anomalies, dental caries, and gingivitis. A questionnaire was administered addressing individual, sociodemographic, and behavioral characteristics as well as dental history. A descriptive analysis was performed, followed by unadjusted and adjusted binary logistic regression analyses. The mean age was 14.1 ± 12.2 years. Individuals with a rare disease were 12.9-fold more likely to have some type of oral problem (95% CI: 3.7-44.7) compared to the group without rare diseases. The prevalence of oral problems was higher among Brazilians with MPS and OI compared to normotypical individuals.

Prevalence of Dental Abnormalities, Soft Tissue Pathologies and Occlusion Disorders in Patients with High BMI: A Cross-sectional Study.

PURPOSE: The relationship between body mass index (BMI) and oral disorders remains unclear. This study examined the prevalence and types of dental abnormalities and oral mucosal lesions among female students with obesity attending a Taif University sports centre. MATERIALS AND METHODS: This non-interventional cross-sectional study enrolled female students with high BMI from a university sports facility using a convivence sampling method. The participants were divided into three BMI groups. Data were collected using an interview and by clinical oral examination. Prevalence and oral disorder types and possible mechanisms linking BMI and dental development were evaluated. RESULTS: Ultimately, 86 female students with obesity were analysed. The mean BMI was 42.8 kg/m2, indicating high obesity levels. A weak although statistically significant correlation was observed between age and BMI (r=0.27), indicating that older students had higher BMI. A statistically significant association was observed between BMI and dental abnormalities (p0.05). The dental abnormality prevalence increased with BMI, ranging from 37.5% to 40.7% in the ≤40 and >45 kg/m2 groups, respectively. Most participants (66.3%) had oral mucosal lesions, with the highest prevalence among participants in the 40-45 kg/m2 group (71.4%). CONCLUSION: A statistically significant relationship was observed between BMI and dental abnormalities; obesity may negatively affect oral health.

Cross-bite and oral habits among Albanian autistic children according to the stages of occlusal development.

This study had two aims. First, we aimed to investigate the prevalence of ACB, PCB, and oral habits among a group of Albanian children with ASD compared with a group of children without ASD. Second, we aimed to identify the associations of ASD with ACB, PCB, and oral habits. The sample inlcuded 125 children with ASD (91 males, 34 females) from 2 special schools for children with disabilities and 2 daily residential centers in Tirana. The control group included 125 children without ASD. The relationships between categorical variables were evaluated via the chi-square test. To identify the potential risk factors for ASD, we performed binary logistic regression. No statistically significant differences were found for CB or oral habits between the primary and adolescent dentition stages. A comparison of children with ASD with CB and oral habits revealed a significant difference in the prevalence of PCB. Binary logistic regression revealed that ACB, PCB and oral habits were not associated with ASD. CB was more prevalent among children with ASD in the primary and mixed dentition stages. Oral habits were more prevalent in the mixed and adolescent dentition stages. However, ASD is not a risk factor for CB or other oral habits.

Oral issues and childhood stress in eight-to-ten-year-old schoolchildren: a case-control study.

OBJECTIVE: The aim of the present study was to investigate whether oral problems, harmful oral habits, and sociodemographic factors are associated with the occurrence of stress in schoolchildren. MATERIALS AND METHODS: A case-control study nested within a cross-sectional study was conducted with a sample of 375 schoolchildren eight to ten years of age in the city of Diamantina, Brazil. The case group (with childhood stress) and control group (without childhood stress) were matched for age and sex at a 1:4 ratio (75 cases to 300 controls). Data collection involved the self-administration of a questionnaire by parents/caregivers addressing sociodemographic characteristics and the child's history of harmful oral habits. The children answered the Child Stress Scale (CSS) and underwent a clinical oral examination to determine the presence/absence of dental caries, malocclusion, and traumatic dental injuries. Data analysis involved the calculation of frequencies, the chi-square test, and conditional logistic regression (95% CI; p ≤ 0.05). RESULTS: The final adjusted conditional logistic regression model showed that dental caries (OR = 1.78, 95% CI: 1.01 - 3.14, p = 0.044) and biting objects (OR = 1.81, 95% CI: 1.02 - 3.22, p = 0.041) remained associated with stress in the schoolchildren analysed. CONCLUSION: The present results showed that children with dental caries and the habit of biting objects were more likely to have childhood stress. CLINICAL RELEVANCE: The study allows paediatric dentists to expand their knowledge with regards to the influence of oral problems and harmful habits on the occurrence of childhood stress and serves as a guide for decision-making related to oral problems in schoolchildren.

Malocclusion in deciduous dentition: a cross-sectional study in a Portuguese preschool population.

PURPOSE: To determine the prevalence of malocclusion in Portuguese preschool children, to characterise occlusion in the deciduous dentition, and to study the relationship between malocclusion, sex, and age. METHODS: This cross-sectional study included 3-6 years old children, from 25 randomly selected kindergartens from the Lisbon district. Data were collected through an oral examination. Malocclusion was defined as the presence of any type of occlusion anomaly (anterior crossbite, edge-to-edge, increased overjet, open bite, deep overbite, posterior crossbite, scissor bite), spacing anomaly (crowding), or dentition anomaly (supernumerary teeth, agenesis, malformations). Canine class, terminal plane of the deciduous second molars and type of Baume arch were also recorded. Statistical analysis included descriptive and chi-squared test (α = 0.05). RESULTS: The sample included 426 children with a global prevalence of malocclusion of 60.6%. Occlusion anomalies were the most prevalent (59.2%), the most frequent being deep overbite (27%), increased overjet (22.1%) and posterior crossbite (14.1%). Crowding had a prevalence of 1.6% and agenesis of 1.4%. Class I canine (57.3%), straight second molar terminal plane (60.1%) and type I Baume arch (53.3%) were the most common. The mean overjet was 2.6 mm (sd = 2.1) and the mean overbite was 2.2 mm (sd = 2.1). Age was associated with the presence of occlusion anomalies (p = 0.03), and increased overjet prevalence was found to be higher in girls (p = 0.03). CONCLUSIONS: The prevalence of malocclusion was high, with occlusion anomalies being the most prevalent. It is important to identify modifiable risk factors associated with malocclusion to prevent this condition in both the deciduous and permanent dentitions.

What are the prevalence and risk factors associated with wire syndrome in dental students? A cross-sectional study.

INTRODUCTION: Wire syndrome (WS) refers to dental displacements that can be described as aberrant, inaccurate, unexplained, or excessive, on teeth still contained by an intact bonded retainer, without detachment or fracture, leading to evolving dental and periodontal, aesthetic and/or functional consequences. The objective of this study was to define the prevalence rate of mandibular WS and the associated risk factors. METHODS: Participants were dental students who had undergone orthodontic treatment and were wearing an intact fixed mandibular retainer. They completed a 20-item questionnaire, after which an extraoral and intraoral clinical examination was conducted. Participants were assigned to either the non-wire syndrome group or the wire syndrome group by two independent practitioners. Univariate and multivariate logistic regression models were used to investigate potential risk factors. RESULTS: A total of 59 students (23.4years±1.7years) were included. Among these, 9 students presented with mandibular WS, resulting in a prevalence rate of 15.25% (95% CI: 6.08%-24.43%). Univariate analysis revealed a significant association between a deep labio-mental fold, a concave profile, and a multi-strand round wire, and an excess risk of WS. The odds ratios were 16.5 (95% CI: 1.9-146.8, P=0.01), 6.4 (95% CI: 1.0-41.0, P=0.05), and 9.0 (95% CI: 1.7-48.7, P=0.01), respectively. Multivariate analysis confirmed these significant associations, except for the concave profile. CONCLUSIONS: The prevalence rate of wire syndrome was 15.25%. Two risk factors associated with WS were identified: a deep labio-mental fold and a multi-strand round wire retainer.

The relationship of anterior occlusion and skeletal variables with the frontal sinus index: An analytical cross-sectional study.

OBJECTIVE: To determine the relationship of anterior occlusion and skeletal variables with the frontal sinus index. METHODS: The retrospective, analytical, cross-sectional, study was conducted from July to November 2020 at Dr Ishratul- Ebad Khan Institute of Oral Health Sciences and Dow Dental College, Dow University of Health Sciences, Karachi, and comprised data from 2015 to 2018 related to pre-treatment lateral cephalograms for determining frontal sinus index and other cephalometric variables. The dental casts were observed for incisor classification. Patients with Class I incisors formed the comparison group, while the rest comprised 5 malocclusion groups. The frontal sinus was traced, and the sinus index was calculated. Data was analysed using STATA 15 and R 3.5.1. RESULTS: Of the 240 subjects, there were 40(16.66%) in each of the 6 groups; 155(64.6%) females and 85(35.4%) males. The mean age of the sample was 21.33±3.52 years (range: 16-29 years). The mean sinus index was higher in all malocclusion groups than the comparison group, but it was significantly higher only in Class II division 2 and anterior open bite groups (p<0.05). The only exception to the trend was Class II division 1 with and without contact in which the value was lower (p>0.05). The anterior cranial base length, sella-nasion mandibular plane angle, and upper incisor palatal plane angle significantly affected the frontal sinus index (p<0.05). CONCLUSIONS: The frontal sinus index could be considered an indicator of harmonious anterior occlusion.

Do symptoms and signs of temporomandibular disorders have an association with breathing pattern: a cross-sectional study on Turkish children and adolescents.

BACKGROUND: This paper aimed to explore the prevalence of temporomandibular disorders (TMDs) signs/symptoms, and to investigate the possible link between signs/symptoms of TMDs and mouth breathing (MB) by evaluating along with other risk factors, in a Turkish subpopulation of children and adolescence. METHODS: This study was conducted with the archival data of the patients who applied with orthodontic complaints. Data on demographic characteristics, family-related factors, systemic status, occlusion, breathing patterns, oral habits, and bruxism were retrieved from the archival records. RESULTS: Nine hundred forty-five children and adolescents with a mean age of 14.82 ± 2.06 years were included in the study. Of the participants, 66% were girls, 60.4% were delivered by C-section, 8.4% of the participants had at least one systemic disease, 9.2% of the participants had allergy, and 4.3% of the participants' parents were divorced, 18.7% have an oral habit, 6.6% have bruxism, 29.8% have malocclusion and 14.1% have MB. Eight-point-five percent of participants have signs/symptoms of TMD. Among them 2.9% have pain, 3.7% have joint sounds, 1.4% have deflection, and 3.9% have deviation. Evaluation of the risk factors revealed a significant relation between the signs/symptoms of TMD and bruxism (OR 8.07 95% CI 4.36-14.92), gender (OR 2.01 95% CI 1.13-3.59), marital status of parents (OR 2.62 95% CI 1.07-6.42), and MB (OR 3.26 95% CI 1.86-5.71). CONCLUSIONS: According to the study's findings, girls and those with bruxism, divorced parents, and MB behavior are more likely to have signs/symptoms of TMD. Age found to have significant effect on the occurrence of the signs/symptoms of TMD alone, but together with other factors the effect of the age is disappeared. Early screening and intervention of MB as well as the signs/symptoms of TMD can help to limit detrimental effects of these conditions on growth, and quality of life of children and adolescents.

Socioeconomic status in life course is associated with dental appearance dissatisfaction.

The present study aimed to investigate the prevalence of dissatisfaction with dental appearance among 24-year-old Brazilian adults and the associated factors in life course. A subsample (n = 720) of the 1982 Pelotas Birth Cohort in southern Brazil was investigated at the ages of 15 and 24 years using clinical (caries and periodontal) examinations and interviews. The outcome was dissatisfaction with dental appearance at the age of 24 years. Covariate variables included socioeconomic factors, oral health, and dissatisfaction with general appearance collected during different periods of life. Poisson regression models with robust variance were applied. The prevalence of dissatisfaction with dental appearance was 43.5% (95%CI: 39.8-47.1). Individuals with downward income mobility (PR = 1.22, 95%CI: 1.07-1.79) and those always poor (PR = 1.21, 95%CI: 1.00-1.57) presented a higher prevalence of dissatisfaction with their dental appearance even after oral health variables and dissatisfaction with general appearance were controlled for. Moderate/severe malocclusion at 15 years (PR = 1.34, 95%CI: 1.13-1.59), highest experience of untreated dental caries at 24 years (PR = 1.82, 95%CI: 1.46-2.27), and dental pain experience at 24 years (PR = 1.29, 95%CI: 1.22-1.75) were associated with the outcome. Also, the prevalence of dissatisfaction with dental appearance was 20% higher (PR = 1.20, 95%CI: 1.01-1.43) among those dissatisfied with their general appearance. Our findings demonstrated a high prevalence of dissatisfaction with dental appearance among young adults. Lifetime economic disadvantage and dental problems (malocclusion at 15 years, untreated dental caries at 24 years, and dental pain at 24 years) were associated with dissatisfaction with dental appearance among young adults.

Evaluation of social appearance concerns and satisfaction after orthognathic surgery.

The main aim of orthognathic surgery is to provide a good occlusion and masticatory function and to achieve positive changes in facial aesthetics. The aim of this study was to determine the reasons behind patients' acceptance of orthognathic surgery and their expectations from this treatment, to assess whether their expectations were met, the change in their self-confidence and their satisfaction, and finally, to use the results obtained to inform future surgical procedures to increase patient satisfaction. The study was designed as a cross-sectional observational study and included 73 people treated with orthognathic surgery (surgery group) and 42 people with minimal crowding who did not require treatment (control group). The study found that the primary reason for requesting orthognathic surgery was to improve facial appearance and that patients had high expectations in this regard. Using the Social Appearance Anxiety Questionnaire and the Expectation and Satisfaction Questionnaire, 73.97 % of patients in our study said the treatment met their expectations and 90.41 % said they were satisfied with the overall results of the surgery. The study also highlighted the importance of surgeon-patient communication and the satisfaction of the patient's environment with the final result in determining patient satisfaction. In conclusion, since patients' high expectations of orthognathic surgery influence treatment success and patient satisfaction, it is important to know and manage patients' expectations before treatment and to have good patient-surgeon communication to increase patient satisfaction after surgery.

A comprehensive national survey on malocclusion prevalence among Palestinian children.

BACKGROUND: This study aims to evaluate the prevalence of malocclusion and orthodontic features among schoolchildren in the West Bank, Palestine. METHODS: A stratified cluster sample of 1278 schoolchildren (620 males, 658 females, mean age 12 years and 5 months (± 0.5)) were examined. Candidates who had not received any previous orthodontic treatment were only included. Dental anomalies like missing and ectopic teeth were recorded. The anteroposterior occlusal relationship was assessed based on Angle classification. Overjet and overbite were measured. Crowding and spacing were recorded subjectively. In addition, crossbite, openbite, and midline displacement were recorded. The chi-square test and descriptive analysis were used statistically. RESULTS: The study found Angle Class I molar relationship in 65%, Class II div 1 in 17%, Class II div 2 in 6%, and Class III in 12% of the sample. An overjet (OJ) of more than 4 mm was present in 17%, and 4% had OJ of more than 6 mm; an OJ of at least 0 mm or less in 36%, and 6% had a reverse OJ. A normal overbite was observed in 53%, while 28% had an increase and 19% had a decreased overbite. An anterior openbite (AOB) was present in 9%, and a scissor bite or anterior crossbite in 6% and 14%, respectively. A posterior crossbite was observed in 12% (9% unilateral and 3% bilateral). Midline displacement was found in (9%). Crowding was observed in 35% and 31% and spacing in 24% and 15% of the maxillary and mandibular arches, respectively. A statistically significant relationship between gender and midline shift, a diastema, spacing in the upper arch, and most dental anomalies was found; males were more affected (p < 0.05). CONCLUSION: This study reported a high prevalence of malocclusion among schoolchildren in Palestine. A collaborative effort should be directed to obtain more monitoring and surveillance of malocclusion more frequently to prevent and control the exacerbation of the problem.

Characterizing infraocclusion in primary molars: prevalence, accompanying findings, and infraocclusion severity and treatment implications.

BACKGROUND: This manuscript investigates the prevalence, classification, accompanying findings, and treatment modalities associated with infraoccluded primary molars. The aim of this study categorizing primary molars based on the severity of infraocclusion and assessing their respective treatment interventions across different severity groups. METHODS: The classification, treatment types, accompanying findings, and the condition of succeeding premolars of infraoccluded molars were documented. Chi-square tests, including Fisher's Exact Chi-square test, Fisher Freeman Halton Exact Chi-square test, and One Sample Chi-square test, were conducted. The predetermined significance level was less than 0.05. RESULTS: The study population consisted of 3132 subjects aged 3 to 15 years, with a prevalence of 4.3% for infraocclusion. Infraocclusion typically manifests between 6 and 9 years of age and predominantly affects mandibular primary molars. Treatment interventions varied based on infraocclusion severity, with more invasive procedures required for severe cases. Accompanying findings associated with infraocclusion include adjacent teeth tipping, significant deviation in midline shifts towards the affected side and increased caries. Additionally, succeeding premolar agenesis was observed in 2% of infraoccluded molars, with extraction rates higher in cases where the successor tooth was mesially or distally located. CONCLUSIONS: The study offers novel insights to dental practitioners concerning the severity and distribution of treatment interventions for infraocclusion. It suggests that more severe cases may necessitate more invasive procedures, with the aim of enhancing patient outcomes through timely intervention and personalized therapeutic strategies.

Orthodontic Status and Association with Oral-Health-Related Quality of Life-A Study of 16-Year-Old Norwegians with a Cleft Lip and Palate.

OBJECTIVE: To assess the association between clinical orthodontic indicators and oral-health-related quality of life, adjusted for socio-demographic factors, focusing on 16-year-old patients with cleft lip and/or palate (CL/P). PARTICIPANTS: One hundred and twenty-two patients with CL/P, representing cleft-lip (CL), cleft-palate (CP), unilateral/bilateral cleft-lip-palate (UCLP/BCLP), enrolled in the national CLP-Team, Bergen, Norway. METHOD: A cross-sectional study by two orthodontists assessing the number of teeth, intermaxillary sagittal relation (ANB-angle), dental arch and occlusion of 16-year-old patients with CL/P. All completed a digital questionnaire including self-reported socio-demographic variables, OHIP-14 questionnaire and dental aesthetics. Cross-tabulations with Pearson's Chi-square test were used to identify associations between self-reported OHRQoL and socio-demographic and clinical indicators. Multiple variable analyses were conducted with binary logistic regression analysis using the odds ratio (OR) and 95% confidence interval (CI) to assess associations between OHRQoL and clinical indicators adjusted for socio-demographic variables. Ethical approval was granted by the regional ethics committee. RESULTS: Patients with UCLP and BCLP had poorer clinical indicators compared to patients with CL and CP (p < 0.05). A total of 80% of the patients had OHIP-14 > 0. The highest oral impact was reported for psychological domains and articulation and the least for functional domains. Respondents with BCLP and those with poor intermaxillary relationships (ANB < 0°) reported a high impact on OHRQoL (p < 0.05). No statistically significant associations between other clinical indicators and socio-demographic variables such as gender, educational aspiration, and place of residence were reported. CONCLUSIONS: The study revealed an association between severe cleft diagnosis, missing teeth, misaligned teeth, negative overjet, and poor OHRQoL, but a statistically significant association was found only between OHRQoL and poor intermaxillary sagittal relations (unfavorable profile). To improve OHRQoL among patients with clefts, there is a need for an individual follow-up and prioritization of oral healthcare.

Expert consensus on pediatric orthodontic therapies of malocclusions in children.

Malocclusion, identified by the World Health Organization (WHO) as one of three major oral diseases, profoundly impacts the dental-maxillofacial functions, facial esthetics, and long-term development of ~260 million children in China. Beyond its physical manifestations, malocclusion also significantly influences the psycho-social well-being of these children. Timely intervention in malocclusion can foster an environment conducive to dental-maxillofacial development and substantially decrease the incidence of malocclusion or reduce the severity and complexity of malocclusion in the permanent dentition, by mitigating the negative impact of abnormal environmental influences on the growth. Early orthodontic treatment encompasses accurate identification and treatment of dental and maxillofacial morphological and functional abnormalities during various stages of dental-maxillofacial development, ranging from fetal stages to the early permanent dentition phase. From an economic and societal standpoint, the urgency for effective early orthodontic treatments for malocclusions in childhood cannot be overstated, underlining its profound practical and social importance. This consensus paper discusses the characteristics and the detrimental effects of malocclusion in children, emphasizing critical need for early treatment. It elaborates on corresponding core principles and fundamental approaches in early orthodontics, proposing comprehensive guidance for preventive and interceptive orthodontic treatment, serving as a reference for clinicians engaged in early orthodontic treatment.

PREVALENCE OF DENTITION, DENTAL ARCHES AND DENTAL ANOMALIES.

Malocclusion can have a negative impact on children's quality of life. Patients with severe malocclusions tend to smile less and look for ways to improve their smile. The mentioned study was conducted in 400 patients aged 3 to 18 years, who applied to the dental clinic for orthodontic treatment regardless of age and gender. The aim of the study was the prevalence of occlusion, dental arches and dental anomalies, most often combined occlusion anomalies, functional disorders, carious and filled teeth and periodontal diseases in the examined patients. According to the results of the research, it was established that the majority of the examined patients were female. Among occlusion anomalies, occlusion class II subclass I was detected with the highest frequency. Almost 11% of the examined had a functional disturbances oral and maxillofacial system. 6% of the examined have an anomaly of the shape of the crown of the teeth. 6.25% of cases have microdontia and 5.5% have macrodontia. 1.17% showed pathological wear and 24.55 enamel hypoplasia. 1% supernumerary tooth, of which 0.75% supernumerary tooth between central incisors, 0.25% supernumerary tooth in other area. Persistent tooth in 3.25% of cases. 5% of retentive teeth are one or several teeth at the same time. 26.75% have one or more dystopian postures. Diastema was detected in 19.75%. Most of the examined patients were female, which is explained by the perception of patients and their parents regarding facial aesthetics in relation to gender. Most of the patients turn to orthodontics in cases of occlusal anomalies that are more aesthetically pronounced and easily perceived by others. In the studied society, oral health and oral care skills are given less importance, as evidenced by high rates of periodontal diseases, caries, and filled teeth. In the mentioned population, it is very important to raise the level of knowledge of the importance of oral health, which is possible by conducting educational events in kindergartens, schools, public gathering places, dental clinics.

Orthognathic Surgery Trending: Retrospective Ten Years Cases Analysis in Nineveh Province, Iraq.

AIMS: The study aimed at analyzing patient's case sheets in regard to the incidence of skeletal discrepancy present in cases and its relation with the demographic profile of the sample. All these are chronicled for more than 10 years periods. METHODOLOGY: This is a retrospective study analysis of the orthognathic case sheets for more than 10 years period. The total numbers of patients are 678. Patient's case sheet was already prepared by the Multi-Disciplinary Team Orthognathic Surgery Clinic in Al-Salam Teaching Hospital, which is the only authorized committee in Nineveh Health Directorate. RESULTS: The highest age percentage is between (18 and 27 y/76%). Angle class III cases are the uppermost cases (36%) from the total. A significant P value is clear at the level ≤0.05 and ≤0.01 between surgery type and discrepancy in anterior segmental osteotomies (upper and lower) which is performed in bi-maxillary protrusion cases and Angle class II cases (0.01**). Similarly, anterior segmental osteotomies (upper jaw only) which are indicated in both open bite and Angle Class II cases documented as a statistically significant P value (0.02*). The positive correlation is shown in all variables with the disharmony or facial discrepancies. Esthetic and beauty as causes for treatment recorded more than function in relation to time series. CONCLUSION: This study documents that patients with skeletal class III accounted for the largest percentage (64%) in the study group. A high increase in patients number seeking treatment for their discrepancy is obvious with time from 2009 till 2022.

Associations between nonnutritive sucking habits, developing malocclusion, and various feeding practices in 3-6-year-old Indian urban children: A case-control study.

BACKGROUND: Nutritive sucking and nonnutritive sucking (NNS) may affect the craniofacial development, differently. AIM AND OBJECTIVES: We investigated associations between NNS habits (NNSHs), developing malocclusion, and various feeding practices in 3-6-year-old children. METHODOLOGY: A sample of 350 children 3-6-year-old from various preschools were selected for this case-control study (94 with NNSH and 256 without NNSH). NNSH (outcome) and feeding practices and developing malocclusions (exposures) were assessed using a structured study tool. RESULTS: The prevalence of NNSH in 3-6-year-old children was 26.8%. The odds (95% [confidence interval (CI)]) of boys compared to girls having NNSH were 0.66 (0.4121-1.706) (P = 0.0290). The overall prevalence of developing malocclusion in 3-6-year-old children was 34.01% out of which open bite was most commonly reported with 12.57% followed by spacing 8.5%, increased overjet 6.8%, crowding 2.2%, posterior crossbite and rotation 1.4%, and overbite 1.14%. Breastfeeding was found to be the most commonly used mode of feeding reported by 53.42% of mothers. It was found that the odds (95% [CI]) of subjects having NNSH were 0.66 (0.4694-0.9460) (P < 0.0001) who were not breastfed as compared to those who were breastfed. Among developing malocclusions, increased overjet with P = 0.0019, open bite with P = 0.0416, and spacing with P = 0.0243 were found to be associated with feeding practices. CONCLUSION: The prevalence of NNSH and developing malocclusions (increased overjet, open bite, and spacing) was 26.8% and 34.01%, respectively. Breastfeeding played a protective role against developing NNSH.

Prevalence of malocclusion and oral health-related factors among pre-school children in Northern Albania.

The aim of the present study was to investigate prevalence and association between malocclusion and caries among pre-school children aged 4-6 years frequenting public kindergartens in Shkodër, the largest city in North Albania. The sample for this descriptive and cross-sectional study included 389 pre-school children aged 4-6 years frequenting 20 public kindergartens in Shkodër, the largest city in North Albania. The participants were divided into two groups according to their caries experience evaluated, as determined by decayed-missing-filled index dmf (World Health Organization criteria) score. Those with dmf score of zero were considered to be free of caries. The prevalence of children with at least one malocclusion trait was 89%. The prevalence of caries was 66% (mean dmf score: 3.63). Increased overbite (43%), followed by increased overjet, were the most prevalent malocclusion traits observed in children with a dmf of zero. Among children with caries, the most prevalent trait was increased overjet (42%) and increased overbite. Almost half of the entire study population had a straight terminal plane and class I canine relationship. There was a similar prevalence of bilateral crossbite. Significant changes (p = 0.008) were observed between the groups with regards to the absence of spacing in the maxillary anterior region. Regression analysis further revealed that children with an absence of maxillary spacing were 2.564-fold more likely to have caries; those with a deepbite were 0.814-fold more likely to have caries. More than half of the children had caries. Increased overjet, overbite, crossbite and maxillary crowding were malocclusion traits observed in the population included in this study. A positive association was identified between maxillary crowding, deepbite and caries. The association between malocclusion and caries, highlights the necessity for an increased awareness of these two conditions that are commonly found among children of pre-school age.
