Orthodontic Study Model Discrepancy Analysis on Mixed Dentition: A Narrative Review

Background: Attention in the form of dental treatment should be given to the phase of children’s teeth that are still in the growth and development stage. The analysis of mixed dentition phase arch is an important criterion in determining the orthodontic treatment plan. Ideally, there is sufficient space so that unerupted teeth can erupt into the oral cavity and not cause crowding of teeth. Several analyzes are needed to confirm the orthodontic diagnosis, one of which is the analysis of the study model. The most widely used alternating mixed dentition analysis is the analysis of the Moyers prediction table and the analysis of the Tanaka-Johnston equation. Both analyzes came from populations of Northern European ancestry but proved unapplicable to populations of various races. Purpose: The purpose of this study aims to determine whether the analysis of the Moyers prediction table and the analysis of the Tanaka-Johnston equation is an accurate analysis if used in several populations through narrative review. Review: Based on the results of the research that has been done, certain populations showed higher prediction results than the actual value. Conclusion: The analysis of the Moyers prediction table and the Tanaka-Johnston equation is not suitable if applied to certain populations, because the results differ from the actual value with the predicted value.

Dental Health Knowledge Improvement about Malocclusion After Oral and Dental Health Empowerment at Miftahul Ulum Melirang Islamic Junior High School, Melirang Village, Bungah District, Gresik

Background: Malocclusion is one of dental health problem that may affect the oral health in adolescences. The dental health education delivered is expected to be able to change the dental health behaviour of individuals or communities from unhealthy to healthy behaviour. Purpose: To increase knowledge of oral health, especially the level of knowledge of malocclusion by means of empowerment of dental health knowledge at Madrasah Tsanawiyah Miftahul Ulum Melirang Junior High School, Gresik. Methods: A total of 100 junior high school children from grade tenth, eleventh, twelfth were included in the study. Data was collected by instructing participants to fill out a pre-test questionnaire on Google drive, then a teledentistry was conducted and ended by filling out a post-test questionnaire to determine the increase in oral health knowledge for evaluation of dental health empowerment. Results: The main level of knowledge of dental and oral health is good (50%), moderate (40%) and low (10%). Knowledge about dental malocclusion is only 40% who have good knowledge about malocclusion, others are low enough to reach 20% knowledge and other respondents have moderate 40%. After the dental health empowerment program, the knowledge of the participant regarding the oral health was enhanced. Conclusion: the dental and oral health empowerment was performed successfully that increased the level of knowledge of children and teachers is still less than optimal about knowledge of malocclusion, so it is necessary to carry out socialization actions regarding the impact of malocclusion.

Recent Advanced Diagnostic Aids in Orthodontics.

Everyone aspires to have a youthful appearance, complete with a beaming grin. By treating skeletal and dental malocclusions that interfere with facial aesthetics, orthodontics helps patients attain a beautiful face and a smile they will be proud of. The diagnosis of the underlying illness or condition serves as the basis for all medical, dental, and surgical operations. Dental professionals all across the world have reaped the benefits of a major scientific advance in recent years. Many measurements may now be seen and quantified more easily using computer-assisted cephalometry. The accuracy and high quality of all dental materials have been enhancedthanks to computer-aided design and computer-aided manufacture. There have been several developments in the realm of orthodontics. The growing use of technology in recent years has transformed every sector, including medicine and dentistry. From Angle's time to today's nanorobotic age, orthodontic ideas, biomaterials, and technology have evolved greatly. It has been extensively utilized for diagnosis, treatment planning, three-dimensional printing, appliance systems, digital storage, integration, and data retrieval. The technology used in orthodontics is always getting better, and this article aims to give an overview of the most recent changes.

Developmental Enamel Defects in Children from the Southern Region of Ecuador.

Developmental defects of enamel (DDEs) are widely observed in children and are related to the appearance of dental caries, malocclusion, tooth sensitivity, and unfavorable esthetic conditions. The objective of this cross-sectional study was to determine the prevalence and distribution of enamel defects present in children aged 6 to 12 years in the provinces located in southern Ecuador. A total of 1606 schoolchildren were examined under the World Health Organization criteria for diagnosis of DDEs. The results are presented using percentage frequency measures and chi-square associations. Some types of DDEs were presented by 50% of the schoolchildren, mainly diffuse opacity, with no statistical differences according to place of residence and/or environment, sex, and age (p > 0.05). In Ecuador, it is necessary to carry out studies on the factors that trigger enamel defects, since they may be associated with the high prevalence of caries already reported in other studies in the country.

LBODP030 A Rare Case Of Partial Lipodystrophy From Mpdl (mandibular Hypoplasia, Deafness, Progeroid, Lipodystrophy Syndrome) Due To Pold1 Gene Mutation

Abstract MDPL (Mandibular hypoplasia, Deafness, Progeroid, Lipodystrophy syndrome) caused by a mutation in the polymerase delta 1 (POLD1) gene is an extremely rare progeroid syndrome associated with partial lipodystrophy. Currently, there are about 24 cases reported worldwide(1), mostly in people of European descent. We are reporting one such rare case in a Hispanic patient. The patient is a 37 year old male from Honduras who was referred to us by genetics for diabetes management. Family members noted extremely thin limbs and he did not walk till 2 years of age. Family history was negative with 8 full siblings, all reportedly healthy. On examination, his BMI was 15.19 kg/m2. He was noted to have birdlike facies with mid-face hypoplasia, beaked nose, retrognathia, dental malocclusion, and protruding maxillary teeth. He also had bilateral proptosis. His extremities were thin, lacking subcutaneous fat and muscle bulk with distal joint contractures in elbow, hands and feet. Genitourinary showed low testicular volumes (<3 ml). Genetic testing revealed a recurring mutation in the active site of POLD1 gene, which is diagnostic for MDPL. His clinical presentation was classic with dysmorphism, deafness, lipodystrophy and metabolic abnormalities. Due to the rarity of the disorder, there is very limited data on management of these patients. A symptom-based management was recommended. In terms of his diabetes, it was diagnosed at age 33 when his HbA1c was 11.2 and he was started on insulin. Patients with this syndrome tend to have insulin resistance. C-peptide was 2.88 ng/ml (ref. range: 0.78 - 5.19 ng/mL) with glucose 160 mg/dL indicating adequate beta-cell reserve; GAD-65 and anti-pancreatic islet cell antibodies were negative. Insulin was weaned off and currently, his diabetes is being managed with diet and lifestyle changes. He was found to have elevated total cholesterol and triglycerides. Hepatic steatosis was seen on liver ultrasonography. He was started on fenofibrate and low-fat diet; lipid panel has normalized. His echocardiogram was normal. In addition, males are known to have hypogonadotropic hypogonadism however this patient had a low testosterone and high FSH and LH, indicative of primary hypogonadism. A scrotal ultrasound was ordered. DXA scan showed low bone mineral density with the lowest Z-score of -3.6 at the lumbar spine. He was started on testosterone replacement with Vitamin D. Testosterone therapy will help replace the testosterone deficiency in addition to slowing down bone loss. MDPL syndrome is an exceedingly rare clinical entity associated with multiple endocrinopathies. We plan to periodically monitor labs and imaging to continue managing this patient with a symptom-based approach.

Tongue-and lip-tie beyond breastfeeding difficulties

The diagnosis and treatment of tethered oral tie tissues, such as ankyloglossia (tongue-tie) and lip-tie, have grown substantially. Although robust evidence indicates that these abnormal anatomic variations are associated with breastfeeding difficulties, impaired craniofacial growth, sleep, speech and posture in children, both diagnosis and treatment of oral ties remain controversial. The oral cavity displays considerable morphological variation across individuals. One of these variations includes tight, restrictive connective tissue between oral structures known as tethered oral tie tissues (TOTs). The clinical view regarding these anomalies has evolved with increasing interest not only in tongue-tie (ankyloglossia) but also in lip-tie [1-3]. Ankyloglossia has been considered a risk factor for breastfeeding difficulties [4-16]. Recent evidence indicates that TOTs can be also associated with whole-body consequences, such as reflux, dental malocclusion, and respiratory disorders, ultimately increasing the risk of sleep and speech disorders, and detrimental changes in posture and eating patterns [13, 17-25]. The prevalence of TOTs is highly variable across populations and is still a matter of ample debate. Currently, there is a lack of consensus on diagnosis criteria, best surgical treatment techniques, and pre- and post-surgery care [19, 26, 27]. Yet, the diagnosis and surgical treatment of TOTs have substantially increased in recent years [28-31]. This mini-review will summarize evidence-based data regarding the cascade of consequences of tongue-tie and lip-tie in children and the main signs and symptoms of these anomalies in newborns. It will also discuss the available evidence on treatment options for TOTs, including pre- and post-surgical care that may enable better outcomes and prevention of possible complications. For a better understanding, tongue-tie and lip-tie will be addressed separately.

Association of malocclusion and trauma in children: A retrospective study.

Malocclusion is considered one of the most prevalent oral issues and it is considered one of the major risk factors for dental trauma. Dental trauma is a distressing experience for children, and they can have long-term physical, esthetic, and psychological effects. Hence, the main aim of this retrospective study is to evaluate the association between dental trauma and malocclusion in children. Four hundred and fifty patients between the age of 8 and 17 years during March 1, 2020-February 31, 2021, with Ellis classes 1, 2, and 3 were included in the study. Association of type of fracture with gender and malocclusion was calculated using Chi-square test. In case of Ellis class 1 fracture, 9.1% of the patients had no malocclusion, 21.8% of them had crowding, 11% of them had spacing, and 21.8% of them had anterior protrusion. In case of Ellis class 2 fracture, 4.3% of them had no malocclusion, 6.4% of them had crowding, 2.8% of them had spacing, and 3.6% of them had anterior protrusion. In case of Ellis class 3 fracture, 2.7% of them had no malocclusion, 6.4% of them had crowding, 4.6% of them had spacing, and 4.6% had anterior protrusion. The results were not statistically significant. Children with anterior protrusion and anterior crowding are more prone to severe damage during traumatic dental injuries.

Clinical Characteristics of Patients with Dental Malocclusion: An Otolaryngologic Perspective.

Purpose: Allergic rhinitis (AR), which is a major cause of upper airway obstruction, may affect the development of the dental malocclusion. This retrospective study was aimed to investigate association between AR and dental malocclusion in otolaryngologic perspectives. Methods: Patients (n = 217) referred to the otolaryngology department before initiating orthodontic treatment were recruited. The frequency and severity of AR symptoms, sinonasal outcome test (SNOT-22) scores, physical examination findings, acoustic rhinometry results, and treatment modalities were retrospectively assessed. Patients with positive skin prick test findings (SPT) (n = 173; orthodontic group) were compared with age- and sex-matched patients being treated for AR (AR group). Results: We found that 76.5% of the enrolled patients had subjective nasal symptoms, and 93.1% patients showed abnormal physical examination findings such as inferior turbinate hypertrophy (82.0%), adenotonsillar hypertrophy (31.8%), or deviated nasal septum (7.4%). The 173 (79.7%) patients with positive SPT results exhibited a significantly higher incidence of rhinorrhoea, sneezing, and inferior turbinate hypertrophy compared to those with negative SPT results. The proportion of patients who underwent pharmacological or surgical treatments was significantly higher among patients with nasal obstruction (92.0%) than among patients without nasal obstruction (36.9%). The frequency and mean visual analogue symptom scores for nasal obstruction, rhinorrhoea, and sneezing, as well as all SNOT-22 domain scores, were significantly higher in the AR group than in the orthodontic group. The minimal cross-sectional area measured with acoustic rhinometry showed no significant difference between groups. Conclusion: Patients with dental malocclusion had a high SPT (+) rate and a high prevalence of structural abnormalities of the upper airway. The early detection and treatment of subclinical AR, other rhinological problems, and structural abnormalities of the upper airway in patients with malocclusion may help us manage malocclusion from an otolaryngologic perspective.

Clinical status and assessment of caries on first permanent molars in a group of 6- to 13-year-old Tunisian school children.

The present survey aimed to highlight the clinical status of first permanent molars (FPMs) among a group of children aged between 6 and 13 years in public primary schools in Tunisia and to determine the association between FPMs' dental caries, gingival bleeding, malocclusion, dental fluorosis, and enamel defects. The survey involved a cross-sectional study based on a dental examination conducted in public primary schools in Monastir Tunisia. A dental caries assessment was performed on FPMs using the International Caries Detection and Assessment Systemclassification; the number of carious lesions in permanent and temporary dentition was established using the decayed/missing/filled teeth (DMFT)index. The Gingival Index and the Dental Aesthetic Index were used to determine the occurrence of gingival bleeding and malocclusions. Dean's index and the modified Development Defects of Enamel index were used to define the enamel defects. The χ2 test was used to assess the difference between more than two groups, and the level of statistical significance was set at .05%. A total of 545 children and 2080 FPMs were examined. The prevalence of dental caries in FPMs was recorded to be 35.8%. The overall mean DMFTindex of the study population was 1.62 and the mean DMFT index was 1.41. The proportion of carious FPMs increased significantly with the age of the children (p < .05). The mandibular first permanent molar presented higher caries prevalence than its maxillary counterpart (p < .05). The presence of surfaces affected by molar incisor hypomineralization was recorded in 4.3% and the presence of surfaces affected by fluorosis was recorded in 4.6% of FPMs. No association was reported between FPMs' dental caries, gingival bleeding, malocclusion, and enamel defects (p > .05). Although the prevalence of caries in FPMs was considered moderate, health promotion programs should be implemented on a large scale to decrease the prevalence of dental caries among school children.

Skeletal discrepancies in patients with skeletal class 2 malocclusion treated at a private dental hospital - an OP report

Aim: The purpose of this study was to determine whether patients with class 2 skeletal malocclusion in a private dental hospital had skeletal discrepancies.Materials and methods: This was a descriptive, retrospective study, and the dental information archiving software was used to collect all the data from the patients who attended the dental clinics at Saveetha Dental College, SIMATS, Chennai, India (DIAS). March 2020 through March 2021 saw the collection of patient records. We gathered and tabulated the data. The gathered data underwent additional processing, was entered into Microsoft Excel, and then went through statistical analysis using IBM SPSS statistics analyzer v.23.0.Results: The current study used a total sample size of 88950 patients. Skeletal class 2 malocclusion was seen in 0.01 percent of cases overall. The data in this study was examined for the occurrence of different skeletal inconsistencies. Results were satisfactory and showed that there were skeletal differences. A gender bias was evident, with 50.4 percent of the sample population being female. Mandibular deficit was the most frequent skeletal discrepancy, and class 2 div 1 dental malocclusion was most frequently detected.Conclusion: Mandibular deficit was shown to be the most common skeletal discrepancy within the constraints of the current investigation, and a substantial correlation between the skeletal discrepancies and the gender of the study group was found.

Analysis of overcorrection to be included for planning clear aligner therapy: a retrospective study.

To provide clinical information on overcorrection to be included in the initial digital setup to make clear aligner therapy (CAT) more efficient. Prescription data for 150 patients (80 women and 70 men; mean age 33.7 ± 12.7 years) treated successfully with CAT (F22 Aligners, Sweden & Martina, Due Carrare, Italy) and requiring only a single, minimal finishing phase were acquired retrospectively. The inclusion criteria were Class I dental malocclusion with only minimal crowding (≤3 mm), 12-20 aligner steps per arch, no use of auxiliaries or interarch elastics, and rotations ≤25° for round-shaped teeth. The prescribed and corrective movements to be achieved in the main and finishing treatment phases, respectively, were quantified by the dedicated clear aligner setup software. The magnitudes of inclination (buccal-lingual crown tipping), angulation (mesial-distal crown tipping), rotation, intrusion, and extrusion were extracted and analyzed by tooth type, maxilla and mandible, and both arches. Descriptive statistics, that is, mean, standard deviation, and percentage, were calculated for each movement investigated. Classification and regression trees (CART) were generated using the model-based recursive partitioning approach, and the corrective movements were correlated with respect to both the amount of the movements prescribed and the tooth type. Statistical significance was set at 5%. Inclination and rotation required the greatest correction, whereas angulation, intrusion, and extrusion required only minimal correction. Expressed as a percentage of prescribed movement, mean corrective movements were 20.5% for inclination, 14.5% angulation, 28.4% rotation, 11.7% extrusion, and 22% intrusion. According to CART, all corrective movements except extrusion depended on both tooth type and the magnitude of prescribed movement. To achieve more efficient CAT, approximately 20% overcorrection should be added to the initial planning phase when planning challenging movements such as inclination and rotation.

Advantages of Interceptive Orthodontic Treatment; Rapid Maxillary Expansion in Children with Malocclusion Resulting from Mouth Breathing Habits

Background: One of the causes of malocclusion in developing children is the practice of mouth breathing. Morphological disturbances may occur during the growth phase in children with chronic mouth breathing. This resulting in the unfavorable development of dentofacial and craniofacial complexes. Mouth breathing in children as a condition has come to the attention of health care professionals. Malocclusion incidence will be decreased and eventually eliminated with the early identification and treatment of these poor oral habits. Purpose: The study determines the benefits of interceptive orthodontics Rapid Maxillary Expansion treatment in children with malocclusion caused by the habit of mouth breathing. Methods: Data were gathered by searching and analyzing literature from electronic databases PubMed, Wiley, and Science Direct in the 2012 and 2022 publication period. Interceptive orthodontics; rapid maxillary expansion; mouth breathing; malocclusion and children keywords were used to conduct the systematic search of the data. Results: One of the most frequent malocclusions is caused by the practice of mouth breathing which narrows the maxillary arch. Some of the characteristic features are decreased distance between nasal cavity’s lateral walls, bilateral or unilateral posterior crossbite, crowding of the anterior teeth, and deep palate.

Crowded Teeth Elimination: Proportional and Controlled Narrowing of Upper Incisors

Anterior teeth crowding when the total width of the teeth is greater than the length of the anterior sextant of the dentition, is the most common dentomaxillary anomaly. In order to eliminate crowding of the anterior teeth the reduction of the proximal enamel is widely used to reduce the width of the teeth and improve conditions for subsequent orthodontic treatment [1-6]. Based on the calculation of the anterior sextant of the dentition using the «golden coefficient», it is possible to determine the optimal width of the central and lateral incisors for the anterior sextants of a given length, when all the anterior teeth will be symmetrical and proportional when they are in the correct position [7-10]. For the proportional lack of place distribution for all frontal teeth, it has been proposed to make the enamel reduction of every tooth from both proximal surfaces according to the calculation, with maintaining of contact surfaces and contact point position. Then orthodontic treatment will not require an expansion of the dental arch

Analysis of Maxillary First Molar Derotation with Invisalign Clear Aligners in Permanent Dentition.

The objective of this study was to examine the distal rotation of mesial rotated maxillary first permanent molars in a sample of Class II dental malocclusion adult patients treated with Invisalign Clear Aligners (CA). Forty patients (20 males, 20 females, 22.4 ± 3.9 years) were included in the study sample (Department of Orthodontics of University of Rome “Tor Vergata”). Inclusion criteria were: Caucasian ancestry, complete permanent dentition with fully erupted upper second molars, Class II molar relationship, absence of tooth or craniofacial anomalies or caries and periodontal diseases. Pre-treatment (T1), post-treatment (T2) digital casts, and final ClinCheck simulation models (T2CC) were analysed. To measure the rotation of maxillary first molars, Henry’s angle (H°) was evaluated. Maxillary first molars with an H° > 11° were considered mesio-rotated (in total 59 teeth). The treatment CA protocol included disto-rotation without distalization movements. At T1, T2 and T2CC five measurements on the collected dental casts were analysed: Henry’s angle (H°); mesial buccal expansion (ME); distal buccal expansion (DE); mesial buccal sagittal (MS); and distal buccal sagittal (DS). A comparison between the results of T2-T1 and T2CC-T2 was performed using a paired t-test. The differences between T2-T1 highlighted a significant distal rotation of the maxillary first molars (−7.4°) and an expansion movement of 2.20 mm for ME and 1.50 mm for DE. In the post-treatment, the mesial buccal cusps shifted of 1.0 mm, while the distal buccal cusps showed a distal movement of 0.9 mm. Analysing the H° comparison between T2CC-T2, the difference was −1.1°. The T2CC-T2 comparison in the sagittal plane showed a difference of 0.9 mm for the MS and 0.7 mm for the DS. The accuracy was 82% for molar derotation movement. In conclusion, CA provides the upper arch expansion associated with the upper first molars’ distal rotation. These movements provide 2 mm of improvement in arch perimeter and molar intercuspation.

Choice of treatment options for Class II Div II cases in young adults by orthodontists

Aim: The purpose of the present research was to assess the choice of treatment utilized by orthodontists in class II div.II malocclusion in case of young adults. Methodology: 8 questions were asked to 50 orthodontists during a survey regarding the treatment options in cases of class II div. II. They were asked about various appliances used as well as relapses in relation to these cases. Descriptive statistical analysis was carried out using standard deviation, mean etc. The result was considered statistically significant when p value was &lt;0.05. Results: Around 64.5% of participants faced problems like crowding of the anterior teeth as the major challenge followed by aberrant molar relationships, overbite depth, retroclination of maxillary incisors, and hypodivergent facial pattern of patients. 22 months is the average time the orthodontists (58%) remove the fixed appliances and follow them with retainers. 71% of participants feel that class II div. II relapse much more often as compared to class II div. I cases. 13.6% of orthodontists relied majorly preferred interdental stripping and tooth contouring. Conclusion: Surgical orthodontics is not preferred by the orthodontists in our study and class II div. II cases shows more relapses.

Retrospective analysis of the treatment of internal disorders of the temporomandibular joint and myofascial pain disorders in the conditions of adult orthodontic reception

BACKGROUND: Internal disorders of the temporomandibular joint (VN TMJ) occur at orthodontic reception no less often than with other types of dental treatment. The main clinical manifestations of VN TMJ are caused by variants of anterior displacement of the articular disc, pathology of the capsular ligamentous apparatus, hypermobility of the mandibular head, and dysfunction of the masticatory muscles. The main symptom of VN TMJ is joint pain (arthralgia) and muscle pain (myalgia). VN TMJ occupies a special place in orthodontic treatment. They can be detected at the initial treatment, and their symptoms can appear at any stage of orthodontic treatment and be a complete surprise for the doctor and the patient, arise after orthodontics, and be associated with it. Since VN TMJ significantly affects the therapeutic process, its outcomes, prognoses, and treatment problems are under the close influence of orthodontists.&#x0D; AIM: To examine the effectiveness of the treatment of VN TMJ and myofascial pain disorders in patients with dental anomalies.&#x0D; MATERIAL AND METHODS: The study retrospectively analyzed case histories of 300 adult patients with dental anomalies in need of orthodontics who underwent examination and treatment in a multidisciplinary dental clinic between 2014 and 2016. The prevalence and structure of VN TMJ were assessed, and myofascial pain disorders (MFDB) and results of their correction were analyzed.&#x0D; RESULTS: A total of 146 (71.5%) patients with myofascial pain and 58 (28.3%) with myofascial facial pain syndrome needed orthodontic treatment more often. In these patients, VN TMJ and maxillary anomalies belonging to class II according to Engle of unilateral distal occlusion, deep bite, and class I with crowding of teeth are more often detected. Internal TMJ disorders with concomitant MFDB in the form of myofascial pain were observed in 168 (82.4%) patients. Myofascial pain disorders without VN TMJ were registered in 36 (17.4%) patients. The overall effectiveness of the treatment of VN TMJ and MFBSD was 46.4% (n=78 patients). No lasting improvement was observed in 35.7% (n=60). Deterioration was registered in 17.8% (n=30). Relapses were noted in 60.7% (n=124). In the treatment of MFDB without VN TMJ, the overall effectiveness of treatment was 5.5% (n=2), stabilization in 50.0% (n=18), and deterioration in 44.4% (n=16).&#x0D; CONCLUSION: Myofascial facial pain is very difficult to treat. In combination with VN, TMJ creates significant and sometimes insurmountable difficulties in adult orthodontics. All this forces specialists to look for new approaches and develop effective ways to optimize orthodontic treatment in the case of TMJ pathology and myofascial pain disorders.

Quality of Orthodontic Records Keeping: A clinical audit

&#x0D; Objectives: To assess the quality of keeping orthodontic records. A further aim was to raise awareness of undertaking clinical audits to improve the quality of patient care.&#x0D; Methods: Retrospective records of 50 patients undergoing orthodontic treatment at the Faculty of Dentistry, University of Benghazi, were collected to assess the quality of clinical record keeping in practice. The assessment was done by one orthodontist, by measuring 11 different criteria. Furthermore, to decide on any future changes to be done. Statistical analysis was done by descriptive analysis.&#x0D; Results: The personal information were taken by 100%. Medical history was consistently checked but not updated or signed. 64% of cases came to the clinic with referral letters. The oral examination showed that 42% of patients had good oral hygiene, with 50% had fair oral hygiene, while, 8% with poor oral hygiene. 38% of patients had carious lesions. A form for treatment plan consent was not used, it had been taking verbally by 98%. The skeletal pattern showed, class I by 42%, class II was 52%, while class III accounted for 6%. On the other hand, dental malocclusion showed the following: 30% of class I, 56% class II division 1, 6% class II division 2 and class III 8%.&#x0D; Conclusion: This self-audit highlights the shortcomings in the collected records. Furthermore, this procedure shows how an audit can be performed in any area of orthodontics to improve the quality of patient care.&#x0D;

Effect of various malocclusion on maximal bite force- a systematic review.

This systematic review evaluates the variation in molar bite force (MBF) with the type and severity of dental malocclusion in young adults with permanent dentition. We searched seven electronic databases until December 31, 2021, and identified 1898 articles, of which 22 full-texts were reviewed. Eight clinical studies with subjects having permanent dentition with various dental malocclusions and quantifying maximal bite force were included for the review. Newcastle Ottawa scale was used to assess the risk of bias and GRADE to study the certainty of evidence. Articles were evaluated for the primary outcome (variation of MBF in different malocclusion groups) and confounding factors affecting MBF. All studies measured MBF in individuals with normal and malocclusion, with 2329 subjects having permanent dentition. A positive correlation of Class I normal occlusion with the bite force was seen compared to Class II and III malocclusion. Unilateral crossbite patients had lesser bite force. Six studies with 1023 males and 1175 females showed MBF more in males than females. In 3 studies (332 subjects), no significant difference for MBF between the right and left sides of the jaws was measured. MBF decreases significantly with vertical and transverse craniofacial and dental discrepancy. Normal sagittal occlusion has more molar bite force than patients with different malocclusions. Also, MBF is more in males than females, and it increases with age. PROSPERO CRD42021249328.
