Hypodontia and Skeletal Malocclusions Among Orthodontic Patients of Kathmandu, Nepal: A Radiographic Study

Objective To assess the association between hypodontia and skeletal malocclusions in orthodontic patients. Materials and Methods This cross-sectional study comprised of orthodontic records of 40 hypodontic patients (12 males and 28 females) and 120 non hypodontic patients (58 males and 62 females) as control group matched for gender and age with the study sample who came to the orthodontic department for their treatment were selected. Orthopantamograms were evaluated for hypodontia, whereas lateral cephalogram were traced to determine the cephalometric parameters. The association between different classes of skeletal malocclusion and hypodontia was determined using Pearson’s Chi-square test and the cephalometric parameters between patients with hypodontia and without hypodontia (controls) were assessed using Student’s t-test. Result In hypodontic group, 19 (47.5%) patients had skeletal class II, 18 (45%) patients had skeletal class I, and only 3 (7.5%) patients had skeletal class III malocclusions. Whereas in non-hypodontic group (control group), 86 (53.75%) patients had skeletal class II, 63 (39.38%) patients had skeletal class I, and 11 (6.87%) patients had skeletal class III malocclusions. There was no statistical difference between hypodontia and different skeletal classes of malocclusions ( p = .654). Cephalometric parameters between the control group and hypodontic group did not reveal any significant difference ( p > .05). Conclusion This study did not find any association between different classes of skeletal malocclusions and hypodontia. The cephalometric skeletal parameters were not significantly different in hypodontic and control group. It is suggested that the patients having hypodontia will be evaluated on an individual basis for their treatment.

A clinical and X-ray analysis of temporomandibular joint bone elements ratio in children and adolescents with distal position of lower jaw

Aim to conduct a clinical and radiological analysis of the temporomandibular joint (TMJ) bone elements ratio in patients of 1217 years old with a distal position of lower jaw.
 Material and methods. We examined 122 patients of two age groups: 1215 years old and 1517 years old. Patients with malocclusion class II formed the main group, the control group consisted of patients with physiological occlusion. Depending on the diagnosis, the patients of the main group were divided into subgroups in accordance with Angle's classification of malocclusion: patients with class II, subclass 1; patients with class II, subclass 2. The TMJ tomograms were analyzed according to the method of N.A. Rabukhina and the method proposed by the authors. The results were compared in patients from different groups.
 Results. The size of the TMJ space in the anterior section in patients with class II subclass 1 malocclusion increases with age from 2.440.14 mm to 2.960.17 mm, P = 0.048, P = 0.008 in comparison with patients with physiological occlusion. In patients with class II subclass 2 the TMJ space increases from 2.920.21 mm to 3.120.19 mm (P = 0.001). In patients with class II subclass 1 in the age group of 1215 years, the value of the angle in habitual occlusion is increased to 20.011.01 on the right (P = 0.035), and to 20.781.11 on the left (P = 0.044). In the group of 1517 years the value of the angle ⟨ is reduced to 16.331.15 on the right (P = 0.04) and to 16.930.93on the left (P = 0.049). In patients with class II subclass 2 malocclusion in the age group of 1517 years, the value of the angle on the right is reduced to 16.471.02 (P = 0.016), on the left to 16.030.86 (P = 0.011). The revealed differences indicate violations of ratio of the TMJ bone elements with age in patients with malocclusion class II. The asymmetry and distal position of the mandibular heads in the TMJ are most prominent in the subgroup of patients with class II subclass 2 malocclusion.
 Conclusion. The method of analyzing angular indicators on the TMJ CBCT data complements the study of the TMJ CBCT data according to the method of N.A. Rabukhina.

Orthosurgical synergism in the management of severe skeletal Class-III malocclusion- A case report

: What is now known as a Class-III malocclusion was initially recognized by Pierre Fauchard. True Class-III malocclusion is a genetically based condition that manifests in childhood. As the youngster reaches the teenage growth spurt, it becomes more obvious. Typically, we will discover a parent or grandparent who is dealing with the same issue. Class-III malocclusion, however, is not a disease. The abnormality itself is a compensatory mechanism to make up for variation that has happened at some point during the course of the individual's development.The case presented here demonstrates the importance of presurgical decompensation, surgical planning, including cephalometric predictions, and mock surgery in the management of severe skeletal Class-III malocclusion. The treatment included comprehensive orthodontic and surgical workup that included bilateral sagittal split osteotomy for mandibular setback of 3mm and LeFort-I osteotomy for maxillary advancement of 3mm. Class-I jaw relationships with a pleasing profile and correctly aligned arches were attained after 2 years of detailed treatment. This led to an aesthetic improvement and a significant increase in the patient's confidence. Class-III skeletal malocclusions can be corrected surgically or through camouflage. However, an ortho-surgical approach may be necessary if the issue cannot be resolved with orthodontics alone. When done correctly, bi-jaw surgery has repeatedly been shown to be quite successful.

Cephalometric Assessment of Condylar Position among Individuals with Different Skeletal Malocclusion Patterns

Introduction: There are variations in growth and orientation of cranial base region where the maxilla and mandible articulate. This leads to differential movement of the maxilla and mandible causing changes in glenoid fossa and condylar position. Therefore, this study was conducted to determine the condylar position in patients with different skeletal sagittal malocclusion patterns. Methods: An analytical cross-sectional study was conducted among 165 individuals, having skeletal Class I, Class II and Class III relationship (55 in each group) selected by convenience sampling method after receiving ethical approval and informed consent. Lateral cephalograms were taken and measurements for determining condylar position were done and compared among three groups. Data were analyzed in SPSS version 16. Kruskal-Wallis H test was used to determine the mean difference in between condylar positions of three skeletal malocclusion patterns and Mann-Whitney U test was done for their pairwise comparison. Results: There was no significant difference in posterior cranial base length (P=0.200) and saddle angle (P=0.517) in three skeletal malocclusion class groups. However, the three malocclusion patterns showed significant differences in gonian angle (P=0.001) and articular angle (P=0.013). Significant moderate negative correlation in saddle angle and articular angle (P<0.001) was observed. Conclusion: The findings of this study concluded that condylar position based on posterior cranial base length was not associated with different skeletal malocclusion patterns. However, articular angle was significantly lower in skeletal class III than in class II.

Pattern of malocclusion in orthodontic patients at a tertiary care centre

Introduction: Malocclusion is the most common dentofacial abnormality in human population, which can cause dental caries, periodontal disease and aesthetic problems. It is closely related to psychosocial wellbeing. The prevalence of malocclusion varies among different age and ethnic groups. The aim of this study was to assess the pattern of malocclusion occurring in orthodontic patients. Method: A 4-year data from 14 Apr 2018 to 13 Apr 2022 were collected retrospectively by the principal investigator (PI) from the pre-treatment record and an acceptable study cast from the Dental Department at Patan Hospital, Patan Academy of Health Sciences. Angle’s classification of malocclusion was used to classify malocclusion. The collected data were entered, and statistical analysis was carried out by using SPSS version 25. Chi-square test was applied to test the significant differences. The comparison was made between male and female and age group 6-12 years and 13 years and above for the Angle’s classification. Result: A total of 384 patients included in the study, female patients were 263(68.5%). Prevalence for malocclusion was 267(69.5%) of Angle’s class I, while Class II and Class III were 111(28.9%) and 6(1.6%) respectively. The study revealed not statistically significant. Majority 372(96.9%) belong to 13 y and above age group while only 12(3.1%) belong to 6-12 y age group. Conclusion: Angle’s Class I malocclusion was most prevalent with the least common being Angle’s Class III malocclusion. No statistically significant relationship was found. Almost all subjects were 13 years and above age group.

Association of Anterior and Posterior occlusal planes with skeletal class I, class II and class III malocclusion

Introduction: The occlusal plane is a very vital in stomatognathic system and the association between anterior occlusal planes and posterior occlusal plane plays an important role during orthodontic treatments. Methods: Lateral cephalometric radiographs of 270 adult patients of the different classes of malocclusion were used. Several angular measurements were measured and compared among all study groups to evaluate the existence of relationship between AOP and POP with skeletal and vertical patterns. Results: The skeletal patterns showed a significant difference in anterior occlusal plane angle relative to both SN plane and FH plane among all classes of malocclusion (p-value =0.001**) having a steeper inclined plane in Class II and flat inclined plane in Class III. POP in relation to FH plane and SN plane showed lowest angle in skeletal Class III and highest in Skeletal Class I patients. Conclusion: The occlusal planes were found to have an impact on the jaw base where the variation in its angulation of different occlusal planes had affected both sagittal and vertical facial patterns. AOP relative to SN and FH were steeper in Class II and flat in Class III, while the POP relative to FH showed the same value in Classes II and III. Keywords: Anterior occlusal plane, Posterior occlusal plane, Malocclusion, Skeletal patterns, Vertical pattern, Lateral cephalometric radiograph.

Evaluation of AI Model for Cephalometric Landmark Classification (TG Dental).

The accuracy of cephalometric landmark identification for malocclusion classification is essential for diagnosis and treatment planning. Identifying these landmarks is often complex and time-consuming for orthodontists. An AI model for classification was recently developed. This model was investigated based on current regulatory considerations as a result of the strict regulations on software systems and the lack of information on artificial intelligence (AI) requirements in this publication. The platform developed by the ITU/WHO for AI is used to assess the models of the application. The auditing procedure assessed the development process concerning medical device regulations, data protection regulations, and ethical considerations. Upon that, the major tasks during the development were evaluated, such as qualification, annotation procedure, and data set attributes. The AI models were investigated under consideration of technical, clinical, regulatory, and ethical considerations. The risk to the patient and user's health can be considered low according to the International Medical Device Regulators Forum (IMDRF) definition. This application facilitates the decision and planning of malocclusion treatment based on lateral cephalograms without cephalometric landmarks. It is comparable with common standards in orthodontic diagnosis.

Success of orthodontic treatment of linguoverted mandibular canine teeth using a direct inclined plane appliance.

This study evaluated the success rate of orthodontic treatment of linguoverted mandibular canines in dogs using a directly applied inclined plane device. Medical records were retrospectively evaluated at 11 veterinary dental specialty hospitals from 1999 to 2021. Malocclusion classes included 41.7% in class 1, 47.2% in class 2, 6.9% in class 3, and 4.2% in class 4. The severity of linguoversion was mild in 7.6% of teeth, moderate in 33.9%, and severe in 58.5%. There was complete resolution of linguoversion in 71.2% of teeth, functional resolution in 25.4%, and failure in 3.4%. The median treatment time was 42 (11-174) days. Adjuvant orthodontic treatments were performed at the same time as the inclined plane in 45.7% of teeth, including active force orthodontics, extractions of non-strategic teeth, gingivectomy, and odontoplasty. While the inclined plane was in place, 31.4% of dogs required an anesthetized appliance adjustment, and at the time of appliance removal, complications occurred in 19.4% of dogs. Of the teeth that had initial resolution, 14.4% had rebound movement that required additional treatment. This study supports the idea that an acrylic inclined plane is a good treatment option for linguoverted mandibular canines, with a 96.6% success rate within a median of 6 weeks. Yet, orthodontic retention may be necessary in these cases to avoid the need for additional therapies.

Determination of Bolton’s Ratio in Different Malocclusions of the Western Region of Saudi Arabian Population: A Retrospective Cross-Sectional Study

Background: Bolton’s ratio is a useful tool in orthodontic studies which helps determine the ratio of dental proportions. It is considered the 7th key to normal occlusion. Variations in different malocclusions can aid in diagnosis and planning the treatment. This study determines Bolton’s overall and anterior ratios for male individuals with different classes of malocclusion in the western region of Saudi Arabia. Methods: Ninety-six study model records were obtained from male patients attending the Orthodontic division of Preventive Dentistry, Faculty of Dentistry at Taif University, Saudi Arabia. The participants’ average age was 19.6 years. The study models were divided into three categories: Angle’s Class 1 (n=40), Angle’s Class 2 (n=36), and Angle’s Class 3 (n=20). To prevent bias, one of the authors measured the study casts using the ORTHOASSISTANT software program at two different time intervals. Intergroup differences were analyzed using one-way ANOVA. Results were considered statistically significant if the p-value of ≤ 0.05. Results: No statistically significant difference was observed in the overall ratio between the three types of malocclusions. However, class 2 and 3 malocclusions demonstrated significant differences in the anterior ratio. Both overall and anterior ratios in this population were higher than normal Bolton’s ratios. Conclusions: Bolton’s overall ratio did not differ significantly between various malocclusions, but Bolton’s anterior ratio did show significant differences between Class 2 and Class 3 malocclusion groups. This highlights the importance of orthodontists’ appropriate diagnosis and treatment planning in such cases.

Measuring tooth size discrepancies using Bolton analysis: a comparative cross-sectional study among major ethnicity in Malaysia

BackgroundThe Bolton analysis is one of the commonly used tooth size analysis or diagnostic tools in deriving a treatment plan for orthodontic patients. Many studies have indicated and concluded that normal measurements for one group should not be considered normal for other ethnic groups. The aims and objectives of this study were to investigate the applicability of Bolton’s ratios in the orthodontic population of Malaysian main ethnics, Malay, Chinese, and Indians. Comparisons were made in terms of size and distribution of tooth size discrepancy in the Malaysian orthodontic population and the findings were converted in terms of millimeters.MethodsHundred fifty pre-orthodontic study casts comprised of 52 Malay, 54 Chinese, and 44 Indian patients were selected. Digital calipers (Fowler Pro-Max) linked to Hamilton Tooth Arch Software were used to measure the tooth width and ratios. Statistical analysis was carried out to test for gender differences (independent t-test), to identify the effects of malocclusion and ethnic groups (Two-way ANOVA), and to compare the means of the current study with Bolton’s standards (one sample t-test).ResultsThis study showed that there was no significant difference between the genders of the sample of each ethnicity. There was no correlation found between ethnic groups and malocclusion classes. There was a significant difference when comparing Bolton values with the Malay sample for both ratios. It was found that more Malay subjects presented with maxillary excess contrary to Chinese and Indians who presented more maxillary deficiency for the anterior and overall ratio.ConclusionThere was a significant difference found between the TSD of the three major ethnicities in Malaysia. The Bolton standards can be applied to Malaysian Chinese and Indians but not to Malays orthodontic populations for both anterior and overall ratios. Subsequently, a specific standard should be used for the Malays orthodontic population. It was found that more Malay subjects presented with maxillary excess contrary to Chinese and Indians who presented more maxillary deficiency for the anterior and overall ratio.

Effect of maxillary expansion combined with orofacial myofunctional therapy on the position of the tongue of children with mouth breathing

Objective:This study aimed to investigate the change of the position of the tongue before and after combined treatment of maxillary expansion and orofacial myofunctional therapy in children with mouth-breathing and skeletal class Ⅱmalocclusion. Methods:A total of 30 children with skeletal class Ⅱ malocclusion and unobstructed upper airway were selected. The 30 children were divided into mouth-breathing group（n=15） and nasal-breathing group（n=15） and CBCT was taken. The images were measured by Invivo5 software. The measurement results of the tongue position of the two groups were analyzed by independent samples t-test. 15 mouth-breathing children with skeletal class Ⅱ malocclusion were selected for maxillary expansion and orofacial myofunctional therapy. CBCT was taken before and after treatment, the measurements were analyzed by paired sample t test with SPSS 27.0 software package. Results:The measurement of the tongue position of the mouth-breathing and nasal-breathing groups were compared, the differences were statistically significant（P<0.05）. The measurement of the tongue position showed significant difference after the combined treatment of maxillary expansion and orofacial myofunctional therapy in children with mouth-breathing and skeletal class Ⅱmalocclusion（P<0.05）. Conclusion:Skeletal class Ⅱ malocclusion children with mouth-breathing have low tongue posture. The combined treatment of maxillary expansion and orofacial myofunctional therapy can change the position of the tongue.

Comparison of self-rated pain and salivary alpha-amylase and cortisol levels during early stages of fixed orthodontic and clear aligner therapy

Objectives To compare self-rated orthodontic pain (OP) and whole salivary alpha-amylase (αA) and cortisol levels (CL) during early stages of fixed orthodontic and clear aligner therapy (CAT). Methods In groups 1 and 2, malocclusions were treated using fixed orthodontic appliances and CAT, respectively. In Group-3, individuals had normal occlusion and had never undergone orthodontic therapy. Self-rated OP was assessed using the visual-analogue-scale at baseline (T0); after 24-hours (T1) of appliance activation; and after 30 days (T2). Unstimulated whole saliva was collected and αA and CL were measured using enzyme-linked immunosorbent assay. p < .01 was considered statistically significant. Results Twenty-four (Group-1), 24(Group-2) and 25 (Group-3) patients were included. In groups 1 and 2, participants had Class-I malocclusion with anterior-crowding in both arches. At baseline (T0) none of the participants reported pain on mastication. In groups 1 (p < .01) and 2 (p < .01), OP was higher at T1 than T2. In groups 1 and 2, αA and CL were higher at T1 (p < .01) than T0 and T2. At T1 and T2, salivary αA and CL were higher in groups 1 (p < .01) and 2 (p < .01) than Group-3. In groups 1 and 2, a significant correlation was recorded between OP and αA (p < .01) and CL (p < .01) at T1 interval. Conclusion Self-rated OP and salivary αA and CL during the early stages of fixed OT and CAT are similar. Whole salivary αA and CL and OP and are high during the first 24 hours of fixed OT and CAT activation.

УСОВЕРШЕНСТВОВАНИЕ КОМПЛЕКСНОЙ ТЕРАПИИ ГИПЕРТРОФИЧЕСКОГО ГИНГИВИТА У ПАЦИЕНТОВ С ПАТОЛОГИЕЙ ПРИКУСА

The prevalence of inflammatory periodontal diseases, and in particular hypertrophic gingivitis, among adolescents ranges from 50 - 99%, which is often combined with malocclusion and this combination is about 70% of cases, which is an urgent and unresolved problem of modern periodontology and orthodontics. Therefore, the study of the issues of correlation between the severity of morphological, functional and aesthetic disorders of the masticatory-speech apparatus and the severity of the inflammatory process in the tissues of the periodontal complex is important and necessary for the development of modern complexes for the treatment of adolescents with hypertrophic gingivitis and malocclusion class 1 according to Angle during the hormonal period. perestroika. The purpose of the study: to optimize the complex treatment of malocclusion in adolescents with hypertrophic gingivitis. 32 patients aged 14 to 17 years with E.H. class I malocclusion. ANGLE and mild edematous hypertrophic gingivitis were included in this study. All patients underwent orthodontic treatment using non-removable orthodontic equipment (brackets), but for periodontal treatment, patients were divided into 2 groups of 16 people, one group underwent traditional conservative periodontal treatment, and the other group of patients underwent removal of dental biofilm using GBT therapy on apparatus "PROPHYLAXIS MASTER". Before treatment, after 6 months and after the removal of orthodontic equipment, an index assessment of the state of periodontal tissues was carried out and a comparison of the average statistical data of teleradiography to study changes in the size of the facial part of the skull before and after orthodontic treatment, as well as a study of the correlation between the studied parameters was carried out for all patients. According to the results of the study, it was found that during orthodontic treatment of adolescents with malocclusion class I according to E.H. ANGLE and GBT-periodontal therapy increases the effectiveness of complex treatment for this category of patients by 40% compared to traditional therapy for inflammatory periodontal diseases at the stages of orthodontic treatment.

Tooth size discrepancies in Kosovar adolescents with different malocclusion classes

The goal of this study was to evaluate tooth size discrepancies in Kosovar adolescents according to the Bolton’s analysis, and to determine the differences between gender and malocclusion classes. A sample of 400 Kosovar adolescents, aged 13–19 years with various malocclusion categories (class I, II, III) according to the Angle’s classification, was randomly selected. The anterior tooth size ratio, overall tooth size ratio, posterior tooth size ratio, as well as distribution of tooth size discrepancies were assessed. The normality of distribution was assessed by the Kolmogorov-Smirnov test, the differences between genders by the Independent Sample T-test, the Mann-Whitney U-test, and differences among malocclusion groups by ANOVA, the Kruskal-Wallis, and the Dunn’s post-hoc tests. The tooth size ratios of men and women did not differ significantly. The results also demonstrated significant differences among the malocclusion classes only for the anterior tooth size ratio (p&lt;0.05). The overall and posterior ratios did not differ significantly within malocclusion classes. The percentages of Kosovar subjects with a deviation of more than 2SD from the Bolton average for the anterior and overall ratios were 41.37 and 23.79, respectively. The genders did not differ significantly regarding tooth size ratios. Among the malocclusion classes, the anterior ratio differed significantly. In Kosovar subjects, tooth size discrepancies tend to be higher compared to Bolton’s averages.

CORRELATION OF MOUTH BREATHING HABITS TO DENTAL MALOCCLUSIONS

Introduction: one of the malocclusion’s etiology is bad habits such as mouth breathing habit. The purpose of this study was to determine the relationship between the mouth breathing habit through with the type of malocclusion. Materials and Method: the sampling method used was purposive sampling obtained from giving questionnaires to parents and clinical examination of the oral cavity of students at SDN 17 Dauh Puri Denpasar. The number of samples with mouth breathing habit were 50 samples. Classification of dentition malocclusion in students was assessed using a modified Dewey Angle Classification. Data analysis used the chi-square test. Results and Discussion: the results of this study were that the mouth breathing habit was more dominant in the Class I Angle type 2 Dewey malocclusion with a total of 25 students (50%) and in the Class I Angle type 4 Dewey malocclusion with a total of 14 students (28%). Conclusion: the conclusion of this study is that there is a significant relationship between the mouth breathing habit and the type of malocclusion.

Evaluation of the influence of hyoid bone position, volume, and types on pharyngeal airway volume and cephalometric measurements.

We aimed to explore the position, morphological, and morphometric properties of the hyoid bone (HB) and to investigate the effect of HB on the pharyngeal airway (PA) volume and cephalometric measurements. A total of 305 patients with CT images were included in the study. DICOM images were transferred to the InVivoDental three-dimensional imaging software. The position of the HB was determined based on the cervical vertebra level and in volume render tab, the bone was classified into six types after all structures around the HB were removed. Also, final bone volume was recorded. In the same tab, the pharyngeal airway volume was divided and measured in three groups (nasopharynx-oropharynx-hypopharynx). The linear and angular measurements were performed on the 3D cephalometric analysis tab. HB was most commonly located in C3 vertebra level (80.3%). While B-type was found to be the most frequent (34%), V-type was the least frequent (8%). The volume of the HB was found to be significantly higher in male (3205 mm3) than female (2606 mm3) patients. Also, it was significantly higher in the C4 vertebra group. The vertical height of the face was positively correlated with the HB volume, C4 level position, and increased oro-nasopharyngeal airway volume. The volume of the HB is found to differ significantly between genders and can potentially serve as a valuable diagnostic tool for understanding respiratory disorders. Its morphometric features are associated with increased face height and airway volume; however, are not related with the skeletal malocclusion classes.

An Association of Morphological Characteristics of Palatal Rugae and Dental Malocclusion in an Adult Indian Population: A Cross-Sectional Study.

Introduction The formation of palatal rugae is completed in the early intrauterine stage, and because of their unique and permanent pattern in each individual, they can be utilized in forensics to identify a person. Objective The primary objective of this study was to determine an association between the rugae pattern and the dental malocclusion system described by Angle. Materials and methods A prospective cross-sectional, observational study was conducted on pretreatment dental casts of 400 subjects in an age range of 18-40 years. The samples were divided according to Angle's system of classification of malocclusion into Class I, Class II, and Class III. The number, length, pattern, and orientation of the three anterior-most primary rugae on both sides of the palatal region were studied. Results Significant differences were noted in the mean number of palatal rugae and mean lengths of rugae 1 and 2 on the right side (p < 0.001) and rugae 3 on the left (p < 0.001) side among the different malocclusion groups. Curved and wavy patterns were predominant, and significant differences were found among the groups (p < 0.05), whereas non-significant differences were observed in the rugae orientation between the groups on the right and left sides. Conclusions The current study showed significant differences in the length, number, and pattern of the palatal rugae among Angle's classes of malocclusion. Clinical implications Palatal rugae can be effectively used to identify dental malocclusion at an early stage and can, therefore, help intercept the developing malocclusion.

Prevalence of dental malocclusion and its gender distribution among dental students at Kabul university of medical science

The current study aims to provide quantitative and qualitative information about the prevalence of dental malocclusions among dental students of Kabul University of Medical Sciences (KUMS) in the orthodontics department of Ali Abad Teaching Dental Clinic that evaluates the relationship of malocclusion between gender and the major causes of malocclusion in society among genders and the tendency of the community toward the treatment of dentoalveolar anomalies. This study was a cross-sectional survey that was done randomly among 133 students, 68 male (51.12%) and 65 female (48.87%), in an age range of 18–25 years old at Kabul University of Medical Sciences, Ali Abad teaching dental clinic faculty of dentistry. show the dental malocclusion classes due to “angle" classification in females in Class I (53.48%), Class II (21.4%), and Class III (23.07%), while in males in Class I (48.33%), Class II (6.66%), and Class III (43.33%). The prevalence rate of crowding was 33% in males and 43% in females. It has been studied and analyzed separately that the most common oral problems in females were dental caries (53.84%). According to our survey (65 female participants), no one had periodontitis, while in males, plaque was at a rate of 28.97%, and the least common was gingivitis (6%), respectively. The occurrence of dental trauma in boys and heredity in girls may be the most important factors for dental malocclusion. Girls were more interested in orthodontic treatments, which may be because they pay more attention to beauty than boys. Moreover, crowding had the highest rate among participants, followed by deep, open bites and edge-to-edge bites.
