Abstract:
Aim:
The aim of this study was to assess the association between lip print pattern and different types of skeletal malocclusion.
Materials and Methods:
A sample of 60 individuals (18–30 years old) with skeletal Class I, Class II Division 1, Class II Division 2, and Class III malocclusion as confirmed by Angle between point A and point B. angle were taken for the study and were named as Groups I, II, III, and IV, respectively. Lip print was recorded by lipstick-paper method and was classified according to Tsuchihashi classification as Type I, Type I', Type II, Type III, Type IV, Type V.
Results:
It was seen that partial vertical groove (PVG) lip pattern was most prevalent for all the groups. In skeletal Class I, PVG lip pattern was most prevalent, whereas in skeletal Class II Division 1, intersecting groove, in skeletal Class II Division 2, PVG, and in skeletal Class III, complete vertical groove were prevalent. The difference between the four malocclusion groups of each type of lip print was significant except for Type II.
Conclusion:
Lip print will help in sorting out participants in more reliable manner in cases of mass disaster or criminal investigations. Furthermore, they help in predicting type of malocclusion beforehand for the successful execution of preventive and interceptive orthodontic procedures.

Abstract:
Background:
Open bite (OB) is a vertical malocclusion and is considered the most challenging malocclusion to manage. The aim of this study was to find out the prevalence and describe the pattern of OB among patients presenting for orthodontic treatment.
Materials and Methods:
Three hundred and twenty-six male and female patients who were presenting for orthodontic treatment of dental malocclusion were retrospectively reviewed. They were screened with cephalometric X-rays. Demographics and type of OBs were retrieved. Data were stored and analyzed using IBM SPSS Statistics for IOS Version 25 (Armonk, NY, USA: IBM Corp).
Results:
Of the 326 cases who presented for the management of different types of malocclusion, 78 (23.9%) had OB. There were 23 (29.5%) males and 55 (70.5%) females with an M: F ratio of 1:2.4. Age ranged from 9 to 40 years with mean ± standard deviation (19.5 ± 6.9). Most of the patients (33, 42.4%) were cases of anterior OB (AOB), 20 (25.6%) were cases of posterior OB (POB), while 25 (32.0%) cases were combined OB (COB). Bulk of the patients had Class I molar relationship (42, 53.8%). Six (7.7%) patients reported being involved in oral habits.
Conclusion:
A high prevalence of 42.4% of AOB, 25.6% of POB, and 32.0% for COB was reported. A population-based study is required in Najran province among preschool and early school children.

Abstract:
Impaction of maxillary central incisors is not a common scenario seen in dental practice, and its treatment is often found to be challenging for a clinician as they are esthetically important. Parents are mostly apprehensive when the front teeth of their kids are missing. The causes for the impaction of maxillary central incisors are many, and one of the reasons is supernumerary teeth. A mesiodens is one common type which is a malformed, peg-like tooth that occurs between the maxillary central incisors. A bilateral tuberculate supernumerary tooth is a rare occurrence in the anterior premaxillary region, and if they occur, they fail to erupt into the oral cavity. They often cause impaction of the maxillary central incisors. This unique case report throws light on a rare case of palatally placed; tuberculate bilaterally impacted mesiodens along with impacted maxillary central incisors and its treatment procedures.

Abstract:
Class III malocclusion is exhibited either due to excessive mandibular growth, deficient maxillary growth, or both. Neither growth modification nor camouflage offers a solution for patients with severe Class III malocclusion. Surgery to realign the jaws or reposition dentoalveolar segments is the possible and stable treatment option. A combination of orthodontic and orthognathic phases offers remarkable results along with enhanced psychosocial acceptance. In this case report, Lefort I osteotomy was performed with maxillary inferior repositioning and advancement in a 25-year-old patient with skeletal Class III.

Abstract:
Alignment of malposed teeth is generally treated using coaxial wires, NiTi wires, or HANT wires. However, when canines which are ectopically erupted are tried to be aligned with NiTi wires, due to their bulky root structure, there is a risk of round tripping of adjacent teeth. This unnecessary round tipping creates load on the anchorage (leading to anchor loss) and prolongs the treatment duration. In this case, a unique approach to align buccally placed canine using a modified transpalatal arch (TPA) has been discussed. This case report describes a 20-year-old female, with a buccally placed left maxillary canine, being placed totally out of the arch. The first premolar was extracted to make space for the canine in the arch. The canine was brought into alignment using a palatal traction with the help of a modified TPA and an E-chain initially and later a closed coil spring attached to a palatal button on the canine.

Abstract:
A simple overview of daily orthodontic practice involves use of brackets, wires and elastomeric modules. However, investigating the underlying effect of orthodontic forces shows various molecular and cellular changes. Also, orthodontics is in close relation with dentofacial orthopedics which involves bone regeneration. In this review, current and future applications of stem cells (SCs) in orthodontics and dentofacial orthopedics have been discussed. For craniofacial anomalies, SCs have been applied to regenerate hard tissue (such as treatment of alveolar cleft) and soft tissue (such as treatment of hemifacial macrosomia). Several attempts have been done to reconstruct impaired temporomandibular joint. Also, SCs with or without bone scaffolds and growth factors have been used to regenerate bone following distraction osteogenesis of mandibular bone or maxillary expansion. Current evidence shows that SCs also have potential to be used to regenerate infrabony alveolar defects and move the teeth into regenerated areas. Future application of SCs in orthodontics could involve accelerating tooth movement, regenerating resorbed roots and expanding tooth movement limitations. However, evidence supporting these roles is weak and further studies are required to evaluate the possibility of these ideas.

Abstract:
Over many decades, medical representatives, researchers, etc., are making an attempt to quantify the force/pressure put by the tongue within the oral cavity. Evaluation of the abovementioned may be done by qualitative or quantitative methods. The aim of this study was to assemble a review of literature regarding the devices to measure tongue strength used by different researchers over a period of time from everywhere the globe. A critical analysis regarding the devices custom-made or used to quantify tongue force was meted out in different words such as “tongue pressure,” “role of tongue,” and “malocclusion” in varied search engines using the Internet. The articles considered were over a period of 60 years approximately, i.e., 1956 dated up to March 2018. In addition, searches were also made within the references of the chosen articles. Every custom-made device has drawbacks in its own. In an overall view, most of the devices measure pressure in just one direction. However, tongue activity throughout the features entails a combination of dynamic and static forces because the tongue is oriented in a diffusion of various positions. The employment of quantitative ways to measure tongue force helps the skilled in the evaluation of orofacial physiology, making the diagnosis of tongue force more reliable, particularly in those subjects with a small strength deficit which are difficult to be noted by clinical evaluation.

Abstract:
Introduction:
To evaluate and compare the tongue pressure exerted on the acrylic button of variable size (10 mm and 14 mm) attached to the loop of trans palatal arch (TPA), placed at two different vertical heights (4 mm and 6 mm) from palatal mucosa during deglutition in hyperdivergent patients.
Materials and Methods:
Tongue pressure was measured in 20 hyperdivergent patients (9 males and 11 females; age range 16–19 years with mean age 18.2 years) using FSR (Force sensing resistor) pressure sensors attached to acrylic button of TPA. Readings were obtained on amplifier attached to another end of sensor. In each patient, the tongue pressure was measured at two different vertical heights of TPA (4 mm and 6 mm) from palatal mucosa. At each vertical height diameter of acrylic button was also varied (10 mm and 14 mm). Hence, a total of 4 variables for each patient were evaluated. Measurements were divided into two groups – Group I (acrylic button of 10 mm size) and Group II (acrylic button of 14 mm size). Groups were further divided into subgroups (A and B) – Group IA (acrylic button of 10 mm size at 4 mm height), Group IB (acrylic button of 10 mm size at 6 mm height), Group IIA (acrylic button of 14 mm size at 4 mm height), and Group IIB (acrylic button of 14 mm size at 6 mm height). Unpaired Student's t-test was used for adequate intra- and inter-group comparisons.
Results:
The mean tongue pressures for Group IIB was maximum (2.11 ± 0.228 N/cm2) > Group IB (1.81 ± 0.169 N/cm2) > Group IIA (1.57 ± 0.167 N/cm2) > Group IA (1.30 ± 0.109 N/cm2) and the difference was statistically significant (P < 0.001) for all the intergroup comparisions.
Conclusion:
The tongue pressure measured on acrylic button of TPA in our study was in the range of 247–400 g (1.30–2.11 N/cm2), which can be used to intrude molars in hyperdivergent individuals, thereby achieving counter-clockwise rotation of mandible.

Abstract:
Objective:
This study aimed to evaluate and compare shape variability of soft-tissue outline of skeletal Class II Division 1 patients with various vertical patterns (low, moderate, and high SN-MP angles) and skeletal normal Class I occlusion patients and to evaluate correlative skeletal and dental variables affecting soft-tissue thickness using cephalometric analysis.
Materials and Methods:
Sixty patients were selected with Class I normal occlusion and Class II Division 1 and divided into four groups based on horizontal and vertical skeletal pattern (SN-MP angles) on lateral cephalograms as Group I (normal occlusion), Group II-L (low angle <27°), Group II-N (normal angle 27°–36°), and Group II-H (high angle ≥ 37°). The correlation and multiple linear regression analysis were used to determine skeletal and dental variables influencing soft tissue characteristics.
Results:
The skeletal Class II patients with a high mandibular plane angle had significantly greater values than the skeletal Class II patients with a low mandibular plane angle for basic lower lip thickness and lower lip length. The measurements in perioral soft-tissue thickness were correlated with an inclination of the upper and lower incisors along with facial depth and facial length in skeletal Class II Division 1 patients.
Conclusion:
Lip strain, lip thickness, and dental inclination must be evaluated based on various skeletal patterns for balanced perioral muscle activity.

Abstract:
Unilateral posterior crossbite with functional mandibular shift occurs as a sequelae of constricted maxillary arch, which is usually seen in children between 3 and 12 years of age. Early treatment of this condition helps prevent facial asymmetry, proper functioning of temporomandibular joint, masticatory muscle, and proper development of dentition. Functional unilateral posterior crossbite correction using fan-shaped expander can provide differential expansion. Fan-shaped expander was used in a patient with constricted maxilla having functional unilateral posterior crossbite with asymmetric condylar position and led to the development of favorable differential expansion and correction of asymmetry.

Abstract:
Objective:
The objective was to assess facial asymmetry in individuals having skeletal Class II malocclusion in Uttar Pradesh population.
Materials and Methods:
A total of sixty individuals (thirty males and thirty females) between 18 and 27 years of age were selected. The pretreatment lateral cephalograms of the samples selected (n = 60) for the study were divided into two groups, Group I and Group II, after which posteroanterior cephalograms were taken for the measurement of asymmetry. All the cephalometric parameters were defined as quantitative variables. The mean and standard deviation (SD) for each measurement was calculated. The results were presented in frequencies, percentages for qualitative data, and mean ± SD for quantitative data. Paired t-test was used to test the significance (P = 0.05 or less) in the difference between the right and left sides of the face. Chi-squared test was used to check the significance of difference in proportions. All the analyses were carried out on MS-Excel and SPSS 16.0 version (Chicago, Inc., Illinois, USA).
Results:
In Group II, the parameters for mandibular morphology and volumetric comparison and the mean of all parameters taken were statistically insignificant, but the mean for condylion-antegonial notch was greater for the right side, and the difference between the left and right sides was statistically significant (P = 0.019). When comparing the cephalometric parameters between the left and right sides in Group I and Group II, none of the mean values were proved to be statistically significant, but the right side parameters revealed to be greater than the left side of the measured parameters.
Conclusion:
All participants showed mild skeletal asymmetry on posteroanterior cephalograms, which was not statistically significant. In Group II, the relative mean of condylar asymmetry was statistically significant, which proves the presence of some amount of condylar asymmetry in this group. The other cephalometric parameters measured in our study showed that the value of the same was greater for the right side than the left side.

Abstract
Introduction:
Dermatoglyphics refers to the study of the intricate dermal ridge configuration on the skin covering the palmar and planter surfaces of the hands and feet. Dermal ridges are usually established by the 24th week of intrauterine life, which remains constant throughout the life. The development of dentition and palate occurs during the same period and also genetically determined as dermatoglyphics. Hence, it can be assumed that hereditary and environmental factors leading to malocclusion may also influence normal fingerprint pattern. Thus, it was decided to assess the correlation between dermatoglyphics patterns and growth patterns in individuals with Skeletal Class I and Skeletal Class II malocclusion.
Materials and Methods:
Ninety individuals aged between 18 and 28 years were divided into Skeletal Class I (Group I n = 45) and Skeletal Class II (Group II n = 45) based on Tweed's and Steiner's analysis. Both the groups were further subdivided according to their growth pattern and named as A, B, and C, respectively, for horizontal, average, and vertical. Fingerprints of both hands were taken by the ink and stamp method. The patterns of Arches, Loops, and Whorls in fingerprints were assessed. The data collected were then statistically evaluated using the Chi-square test.
Observations:
In Skeletal Class I subjects, there was increased frequency of occurrence of whorl-pattern in thumb, plain-arches in little, index, and ring finger, and ulnar-loops in middle finger, whereas in Skeletal Class II subjects, radial-loops were more in number in ring and index finger, plain-arches in little finger, ulnar-loops in the middle finger, and whorl-pattern in the thumb same as Skeletal Class I.
Conclusion:
No significant correlation was observed between dermatoglyphics and various growth patterns. However, further studies must be conducted on large sample size to validate the findings

Abstract:
Objective:
The objective of this study is to assess the reproducibility of cephalometric measurements derived from an application designed for handheld (smartphone) devices and manual cephalometry.
Materials and Methods:
Thirty pretreatment lateral cephalograms obtained from the same digital cephalostat were analyzed. Tracings were done using CephNinja for iPhone (Cyncronus) and manually by the hand on acetate sheets. Cephalometric landmarks and angular and linear measurements were recorded. All tracings were performed by the same investigator.
Statistical Analysis:
To evaluate reproducibility, for each cephalometric measurement, the agreement between the value derived from CephNinja, and that measured manually was assessed with the intraclass correlation coefficient (ICC). Agreement was rated as low for an ICC <0.75 and an ICC >0.75 was considered indicative of good agreement. Furthermore, differences in measurements between those derived from CephNinja application and manual tracing were statistically evaluated (P < 0.05).
Results:
All the measurements had ICC >0.75, indicating high agreement among both the tracing methods. Differences in measurements between CephNinja and hand tracing were not statistically significant for any of the cephalometric parameters.
Conclusion(s):
Handheld (smartphone)-assisted cephalometric analysis shows good agreement with manual tracing and can be employed for clinical decision-making.

Abstract:
Objective:
The purpose of this study was to establish lateral cephalometric soft-tissue norms for the adolescent North Indian population.
Materials and Methods:
Three hundred and thirty-three Indian adults of age group 18–30 years were selected. The standardized lateral cephalometric radiograph was taken for each subject. Fourteen linear measurements were recorded on each lateral cephalometric radiograph. Statistical analysis was done using the Statistical Package for the Social Sciences (SPSS 26). Group differences were analyzed with independent t-test.
Results:
The results of the study showed significant gender dimorphism, with men having thicker soft tissue structures, larger vertical dimensions, than women.
Conclusion:
Significant gender dimorphism was evident within the local population suggesting the necessity for a separate set of norms for males and females. Distinct ethnic differences were found between Caucasians and the North Indian population that were statistically significant, highlighting the importance of defining separate set of norms for ethnic groups.

Aim:
The purpose of this study was to investigate the length of the styloid process (SP) in different skeletal patterns and stages of skeletal maturation.
Materials and Methods:
Radiographs involving SP (n = 158; 77 female and 81 male, age with a mean value of 12.84 ± 1.94 years) were evaluated retrospectively. Class I group included 52 subjects (0 ≤ ANB ≤4), Class II group included 57 subjects (ANB>4), and Class III group included 49 subjects (ANB <0). The length of the SP was measured in Photoshop CS5 software (Adobe Systems Inc., San Jose, CA, USA). Skeletal maturation stages were determined by the evaluation of hand-wrist radiographs and lateral cephalometric radiographs. The data were analyzed using Student's t-test and one-way ANOVA.
Results:
Statistically significant difference in the length of the SP was found between Class I and Class II group (P ≤≤≤05). The mean length of the SP was 30.68 ± 9.69 mm in Class I group and 34.63 ± 5.87 mm in Class II group. No statistically significant difference was found in between skeletal maturation stages of the groups neither in the bilateral length of the SP between genders.
Conclusion:
The risk of Eagle syndrome in skeletal Class II malocclusion might be higher. In addition, when a patient is referred with pain in the temporomandibular area with skeletal Class II anomaly, SP elongation should be considered besides the joint problems.

Abstract:
Introduction:
Canines are perceived as cornerstones of the dental arch and plays an essential role in maintaining the facial coordination. When impacted, these functions are lost. We present the prevalence and radiographic presentation of distinctive bilateral maxillary canine.
Materials and Methods:
This was a retrospective study of patients presenting for routine dental treatment between 2018 and 2020 at a dental center, Najran. A total of 2016 panoramic radiographs were screened and all patients with bilateral impacted canines were further screened radiologically using cone beam computed tomography. Data such demographics and presence of bilateral maxillary impacted canines were identified. Data analyzed using IBM SPSS Statistics for IOS Version 25 (Armonk, NY, USA: IBM Corp).
Results:
A total of 2016 panoramic radiographs were examined out of which 149 cases were the total impacted canines. Of these, 42 cases were bilateral impacted maxillary canines in comparable migration tract with a prevalence rate of 28.2%. There were 18 males and 24 females with an M: F of 1:1.3. Age ranged from 15 to 75 years with mean age ± standard deviation (27.9 ± 10.6) years. We observed the bilateral impacted canine positions were in relation to the central and lateral incisors in the anterio-posterior plane and the cervical and root portions of the roots of the central and lateral incisors in the inferior-superior plane. We attempted to group them into 3 main types (Types 1-3) with 3 subtypes (Subtypes a-c) each.
Limitations:
This a hospital based study and findings may not be generalized. Population based study is which is required to find out the prevalent rate in the community.
Conclusion:
These observed positions can be used to predict the favorability or otherwise of orthodontic traction of the impacted bilateral canines.

Abstract:
A 13-year-old patient presented with Angle's Class II subdivision right malocclusion with anterior crowding, protruded lower incisors, and a lower arch that was skewed to the left. A morphological lower midline shift of 3 mm to the left was detected. Following extraction of the upper and lower first premolars, full-arch 0.022” MBT™ appliances were placed in both arches. A 0.018” × 0.025” stainless steel archwire was split into two posterior segments and an anterior segment from the right lateral incisor to the left canine including an open vertical helical loop extending apically toward the center of resistance of the consolidated anterior segment. Subsequently, a 0.017” × 0.025” titanium–molybdenum alloy cantilever spring from the right first molar auxiliary tube was bent buccally and connected to the loop with an elastomeric chain to achieve lower midline correction by translation. Midline correction with the use of segmented-wire technique and cantilever spring provides an effective method of incisor movement by translation with minimal side effects.
