Abstract:
Artificial intelligence (AI) and machine learning (ML) are powerful tools that can be utilized to overcome some of the clinical problems that orthodontists face daily. With the availability of more data, better AI and ML systems should be expected to be developed that will help orthodontists to practise more efficiently and improve the quality of care. AI is a subfield of computer science concerned with developing computers and programs that have the ability to perceive information and reason, and ultimately, convert that information into intelligent actions. The future may be purely digitized, at the comforts of our home, with orthodontists developing neural programs with orthodontic decision markers to aid in developing AI for patients to take less visits, make more use of their time using orthodontic appliances, and enhance the quality of work. This article will briefly discuss the contributions AI and ML in orthodontics, its history and various uses in orthodontics in specific, and the possibility of development.

Introduction:
The smile is one of the most effective means by which people convey their emotions and from a social standpoint, it is viewed frontally more often than in profile. Smiles can be either posed or spontaneous. Peck and Peck classified smiles as Stages I and II, and Ackerman et al. classified smiles into two basic types: the social smile and the enjoyment smile. Each type involves a different anatomic presentation of the elements of the display zone. Smile characteristics are determined by the interplay of static and dynamic relationships between the dentoskeletal and soft-tissue components of the face. Hence, a study was planned to understand the influence of various skeletal and dentoalveolar parameters on smile esthetics in different malocclusion groups.
Materials and Methods:
Sixty subjects in the age range of 17–25 years were selected and skeletally divided into Groups I and II on the basis of beta angle, ANB angle, and Wits appraisal. Group II was further subdivided into two groups on the basis of Angle's classification of the malocclusion. Various skeletal and dental parameters were measured on cephalogram and smile measurements were made on facial photographs in Adobe Photoshop. Various statistical tests were applied for assessment and comparison of various skeletal and dentoalveolar parameters and their correlation with smile esthetics were in different malocclusion groups.
Results:
Upper lip length was maximum in Class II div 2 malocclusion patients and least in Class I malocclusion patients. It was maximum in horizontal growth pattern patients. It decreased with the increase in proclination of upper incisors. Maxillary incisal display at rest and smile was maximum in Class II div 1 malocclusion patients and least in Class II div 2 malocclusion patients. It was maximum in vertical growth pattern individuals. It increased with the increase in proclination of upper incisors. A similar tendency was shown by the Morley ratio and modified smile. Lip competency was maximum in Class II div 2 patients and minimum in Class II div 1 patients. It was maximum in horizontal growth pattern patients. Proclination of the incisors decreased the lip competency.
Conclusions:
Different skeletal patterns exhibit their characteristic smile features. Orthodontic treatment should be planned considering the correlation of skeletal and dental effects on smile esthetics.

Objective:
There are very limited studies which have investigated the relationship between maxillary sinus findings and skeletal malocclusion based on cone-beam computed tomography (CBCT). The objectives of this study were to determine the relationship between the patients' skeletal malocclusion and the maxillary sinus findings in ethnic Kashmiri population.
Materials and Methods:
A total of 45 CBCT scans were examined and divided into three groups according to skeletal classification. Two experienced observers reviewed the CBCT images and recorded all maxillary sinus findings. The patients' skeletal malocclusion, the thickness of the Schneiderian membrane, and the pathologic maxillary sinus findings were evaluated.
Results:
The maxillary sinus findings were classified into five groups: 0 = no finding, 1 = mucosal thickening, 2 = polypoidal thickening, 3 = partial opacification, and 4 = total opacification. The statistical analysis showed that there was no correlation between the skeletal malocclusion and pathological maxillary sinus findings. However, there were significant differences in the Schneiderian membrane thicknesses between the groups.
Conclusion:
The Schneiderian membrane thickness was significantly different for Class II and Class III patients (P = 0.002). It was lowest for Class II and highest for Class III group. The relationship between pathological maxillary sinus findings and skeletal malocclusions was statistically insignificant (P > 0.05).

Abstract
Traditional methods of distalization in maxillary arch require patient cooperation with headgear or elastics, which are awkward for the patient. Hence, numerous intraoral procedures have been offered to reduce patient discomfort. In continuance with such efforts, our aim is to present a successful method of unilateral en-masse distalization using miniplate. Treatment results were evaluated using lateral cephalogram and dental models. Findings suggested that miniplate is effective method of correcting unilateral Class II relationship.

Abstract:
This article compares the treatment outcome between two patients when en-masse intrusion and retraction of the maxillary anterior teeth were performed with mini-implants placed at different sites. Both the patients had a skeletal Class II malocclusion with Angle's Class I molar relation, Class I canine relation, proclination of upper and lower anterior teeth. In the first case, intrusion and retraction was done with conventional friction mechanics for space closure and an intrusive force from a mini-implant placed in the midline. In the second case, intrusion and retraction were done with the application of force from the anterior attachments to mini-implants placed between the second premolars and first permanent molar bilaterally. There was intrusion of the maxillary anterior teeth with both mechanics. However, the evaluation of treatment outcome at the end of space closure showed mesial movement of the maxillary first permanent molar in the first case. In the second case, distal movement and intrusion of the maxillary first permanent molar and decrease in the lower anterior facial height was noted. The mechanics in the first case can be applied for intrusion and retraction of maxillary anterior teeth when anchorage requirement is not critical. The mechanics described in the second case can be used for intrusion and retraction of maxillary anterior teeth in cases with a very high anchorage need and will be beneficial in patients with vertical growth pattern.

Abstract:
This review article presents various fixed functional appliances that have been developed all these years with the aim of correcting Class II malocclusion. Class II malocclusion though multifactorial in etiology, but the main cause is mandibular retrognathia. The treatment aims to modify the direction and amount of mandibular growth rather than restricting the development of the maxilla. Hence, the various appliances were developed removable and fixed with the aim to correct Class II malocclusion. Fixed functional appliances were developed with the aim to correct Class II malocclusion without the need of patient compliance, which was a major concern toward removable functional appliances.

Abstract:
Objective:
To evaluate the facial profile view perceived as most attractive and whether this attractiveness was influenced in a neutral and smiling face.
Methodology:
Sixty participants (20 each of laypersons, dentists, and orthodontists) were chosen for the study. Their facial photos were taken along with professional models' with normal occlusion. Participants were asked to rate self and model photos using the Visual Analog Scale (VAS) based on attractiveness; select most attractive face by looking at panels with 0°, 30°, 45°, 60°, and 90° rotated facial photos of neutral and smiling for models and self; select most attractive photo from the combination panels of neutral and smiling photos of self and model.
Results:
VAS scores by orthodontists for both neutral and smiling faces for both self and model were more or less similar. Dentists and laypersons found smiling photographs more attractive. The 45 angle was perceived most attractive in self and model for both the neutral and smiling categories separately by all three groups. In the combination category, orthodontist perceived the 0° smiling (model) as the most attractive followed by 45° smiling, whereas dentists and laypersons found 45° smiling photographs most attractive.
Conclusion:
The 45° profile view was most preferred by all three groups when assessing self as well as models. Smiling photographs of both self and model are considered more attractive than neutral photographs.

Introduction:
As we witness the soft-tissue paradigm, treating the face becomes more important than just treating the hard tissue variables. Therefore, it becomes crucial to quantify the soft-tissue response to changes in the hard tissue following orthodontic treatment.
Purpose of the Study:
To determine lip morphology changes after first premolar extractions in patients with bimaxillary protrusion as ratios of hard and soft-tissue changes.
Materials and Methods:
The sample consisted of pretreatment and posttreatment lateral cephalograms of 15 subjects with Class I bimaxillary protrusion who had undergone orthodontic treatment with four first premolars extraction and retraction of upper and lower incisors. Pre- and post-treatment lateral cephalograms were traced and superimposed by using SN-7˚ plane. Sixteen linear measurements were made. Statistical analysis was performed to analyze the co-relation between the hard and soft tissue change by Pearson's correlation. Stepwise multiple regression were made to determine factors that related with lip changes.
Results:
Significant changes after treatment were found both in dental and lip analysis. The equations of upper and lower lip changes in sagittal and vertical dimensions were derived.
Conclusion:
Stepwise multiple regression analysis revealed that a 1 mm retraction of the maxillary incisor cervical point would produce a 0.59 mm retraction of upper lip and 1 mm retraction of the mandibular incisor cervical point would produce 0.89 mm retraction of the lower lip. The predictability of this study may be helpful for the clinician in predicting the amount of change in profile of the patient post treatment, thus aiding in planning the treatment

Introduction:
Symmetry and balance in the facial morphology is an important factor determining facial attractiveness. Unilateral posterior crossbite is a common form of posterior crossbite that is usually associated with a functional mandibular shift which might, in the long run, lead to mandibular asymmetry. Thus, there was a need to study this malocclusion and its influence on the facial symmetry in young adults as any factor contributing to alteration in facial symmetry requires evaluation. The purpose of the study was to assess the condylar symmetry in patients with unilateral posterior crossbite.
Materials and Methodology:
The study was conducted on the pretreatment orthopantomograms (OPGs) of sixty cases, out of which thirty had unilateral posterior crossbite (crossbite group) and thirty had normal occlusion in the transverse plane (control group). The Condylar height(CH), Ramal height(RH), and Condylar + Ramal height(CH+RH) were compared within the groups, and their asymmetry indices were compared between the groups using ANOVA test.
Results:
The CH and CH + RH were significantly reduced on the crossbite side as compared to the normal side in the unilateral posterior crossbite group. The asymmetry indices were increased in the unilateral posterior crossbite group as compared to the control group.
Discussion:
OPGs can be used to evaluate vertical mandibular asymmetry. The condylar asymmetry index was increased in the group with unilateral posterior crossbite indicating a greater asymmetry between the two condyles in that group as compared to the control group. The finding was in concordance with a study done in the past.
Conclusion:
The unilateral posterior crossbite group showed reduced CH and CH + RH values on the crossbite side in comparison to the noncrossbite side. The same group showed a greater CH index (more than 3%) as compared to the control group, indicating that the patients with unilateral crossbite develop asymmetry in the mandibular condyle region.

Abstract:
Background:
The aim of the study was to compare and evaluate the frictional resistance of clarity advanced ceramic brackets, metal insert ceramic bracket, and conventional metal brackets with Nickel–titanium wire and stainless-steel archwire of varying dimensions.
Materials and Methods:
The sample size with 80% power was 45. The samples were divided into three groups each group consisting of 15, Group 1 – Clarity Advanced Ceramic Brackets (3M Unitek). Group 2 – Metal insert Ceramic Brackets (3M Unitek). Group 3 – Conventional Metal Brackets, the control group (3M Unitek). The wires used for testing were 0.016” Niti, 0.017 ×× 0.025” Niti and 0.019 ×× 0.025” SS.
Results:
In the present study, it was found that wire material (nickel titanium) had an effect on friction. It was found that metal insert ceramic bracket exhibited similar frictional resistance when compared to metal brackets for 0.017 × ×0.025” Niti and 0.019 × 0.025” SS wires. The Clarity Advanced bracket had the highest frictional resistance followed by metal insert ceramic and least with the conventional metal.
Conclusion:
Clarity advanced can be the bracket of choice for the esthetically discerning patients who do not require extraction for orthodontic reasons, but the high frictional resistance in relation to larger rectangular Niti archwires should be considered. In adult patients who require extraction in the treatment plan, metal insert ceramic brackets are definitely a pleasing alternative when compared to metal brackets.

ABSTRACT
An 11-year-old female patient presented with a chief complaint of labially blocked out maxillary canines and irregular teeth in the upper arch. Clinical examination and evaluation revealed an Angle's Class II malocclusion on an underlying Class II skeletal base with a crowded maxillary arch, blocked out maxillary canines, mild crowding in the mandibular arch, convex profile, and obtuse nasolabial angle. Her skeletal maturity status was Stage III of the cervical vertebrae maturity index (CVMI). A nonextraction treatment plan was considered for this case, which involves bilateral permanent first molar distalization of the maxillary arch using Jones jig distalizer followed by fixed orthodontic mechanotherapy using 022 MBT prescription. The posttreatment outcome shows an appreciable improvement in facial esthetics and occlusion. Further postorthodontic phase has retained a stable occlusion and pleasing facial profile.

Abstract:
The use of miniscrews (MSs) as temporary anchorage devices in orthodontics has gained increased attention among researchers in recent years. However, these screws are usually used in permanent dentition. This case report discusses a patient for which an MS was used. An 11-year-old male with mixed dentition presented an ectopic eruption in his mandibular right canine had ectopic eruption. This altered pattern of eruption was corrected using surgical exposure and orthodontic traction with an elastic chain, assisted by a 2 mm × 10 mm interradicular MS placed between the patient's first and second lower deciduous molars. After 5 months with this traction, the patient's right lower cuspid ectopic guide was corrected. This use of an interradicular MS in mixed dentition was found to be both useful and safe.

Abstract:
Orthodontic treatment is, possibly, in terms of duration extent, the lengthiest dental procedure performed. There will be an increased favorable attitude for orthodontic treatment if the duration of the orthodontic treatment is reduced. Unfortunately, long-term orthodontic treatment also poses several disadvantages like a higher predisposition to dental caries, gingival recession, and root resorption. Quickening orthodontic tooth movement (OTM), i.e., accelerating, can remarkably decrease treatment time and side effects. Orthodontic treatment comprises the response of the tissues surrounding the tooth on which the force is being applied that happens on a cellular, mechanical level, and chemical. So, to improve the body's response to these orthodontic forces, various ways were found to accelerate the treatment, such as surgical methods (corticotomy, piezosurgery, etc.), mechanical/physical stimulation methods (vibration, lasers), drugs, etc., Hence, this review captures the current knowledge on accelerated OTM.

Abstract:
To summarize the details on severe acute respiratory syndrome-coronavirus-2 (SARS-Cov-2) viral infection and the effects of this infection on care of patients with orofacial clefts and provision of guidelines for orofacial cleft surgeries during Corona virus disease 2019 (COVID-19) by using recent available literature. PubMed and Google Scholar and current reports from major health bodies such as the Centers of Disease Control and Prevention, World Health Organization, National Institutes of Health, and major national associations of cleft lip and palate were searched for information which is relevant from orthodontic care for orofacial cleft point of view. Major priority is given to recent articles and peer-reviewed articles. Narration is done due to limitations in the quality of evidence and rapidly evolving information on the nature of COVID-19. Major relevance to the dental field is human-to human transmission of SARS-CoV-2. People who are infected mostly show mild symptoms, but patients with advanced age or any underlying disease or comorbidity may show severe multiorgan complications. During the COVID-19 pandemic, it is important to maintain social distancing and minimize direct contact. Most clinics and hospitals have determined that multidisciplinary visits, feeding, and speech-language evaluations are largely nonessential and can tolerate a delay. A specific plan with good foundation should be followed for emergency orthodontic care with effective communication and triage.

Abstract:
Background:
The purpose of the study is to qualitatively evaluate the ultramorphology, surface roughness, and clinical manifestations on dental health after various stripping, polishing, and postpolishing enamel protection methods which were followed by various researchers to sum up the more pragmatic and less pragmatic results through the research methodology of content analysis.
Objectives:
To qualitatively and inductively evaluate various stripping, polishing, and postpolishing enamel protection methods on ultramorphology and enamel surface roughness along with its clinical effects on dental health after thorough content analysis to provide a sound knowledge to the clinician to justify their decisions related to interproximal reduction (IPR), to make it an extremely useful space gaining tool if used with due caution.
Materials and Methods:
A comprehensive search of articles related to this study was collected from the past 25 years and a conceptual type of content analysis of all the selected articles was done. Inferences obtained through the analysis of the documented research data were then summed up in tabular form.
Results:
The results summated to the very important fact that all stripping methods microscopically leave a roughened enamel surface but clinically have no deleterious effects on dental health if performed judiciously followed by appropriate polishing and postpolishing protection methods.
Conclusion:
It can be determined that IPR should be carried out with greatest caution when using coarser stripping devices followed by prolonged polishing, but cautious use of finer stripping devices could be a better choice along with suitable polishing and protection methods.

Abstract:
Aim:
To introduce a new cephalometric measurement called P-angle using three skeletal landmarks&#s8212;point S, point Gn, and point A, to evaluate the sagittal relationship between the maxilla and mandible.
Materials and Methods:
A total of 130 pretreatment lateral cephalograms were selected and segregated into skeletal Class I, II, and III groups based on W-angle and ANB angle. It included 50 Class I (25 males and 25 females), 50 Class II (25 males and 25 females), and 30 Class III (13 males and 17 females) skeletal pattern patients. The P angle was formed between the line from point A perpendicular to the S-Gn line and line A-Gn. The P-angle and W-angle were measured in each patient. Data was entered in MS Excel sheet and analyzed by using SPSS software 24.0 version IBM USA. The mean and standard deviation of P-angle and W-angle was calculated and were compared using an unpaired t-test.
Results:
The unpaired t-test results showed that there is no significant difference between P-angle and W-angle in Class I, Class II, and Class III skeletal pattern.
Conclusion:
P-angle can be used as an adjunct for W-angle during pretreatment cephalometric tracing.
