Abstract:
Background:
In the field of orthodontics and dentofacial orthopedics, for treatment of malocclusion, diagnosis of facial skeletal type is one of the important aspects. Sometimes, cephalograms are not enough to determine the facial skeletal pattern. Hence, the relationship between sella turcica and other facial skeletal patterns can guide us to determine the proper facial skeletal type and can also help in treatment planning.
Aims:
The aim of the study was to investigate the normalcy of the dimensions of sella turcica and comparison of the relationship of sella turcica with different skeletal malocclusions.
Materials and Methods:
A total of 90 pretreatment digital lateral cephalograms were selected according to the criteria and grouped into 3 groups: Group 1: Class I (n = 30), Group 2: Class II (n = 30), and Group 3: Class III (n = 30). Lateral cephalograms were traced and studied on the basis of sella turcica. The following linear measurements were recorded: length, depth, and diameter of the sella.
Statistical Analysis Used:
Data were subjected to descriptive analysis for mean and standard deviation of all variables and ranges. ANOVA and a post hoc test (Bonferroni and Sidak) were used for multiple comparisons. P <0.05 was considered as the level for statistically significant data.
Results:
The linear measurements of length and diameter showed statistically significant differences in Class I, Class II, and Class III (P = 0.005). However, depth showed no statistically significant difference in the groups.
Conclusions:
The importance of sella turcica is established and normalcy is set by statistical analysis, and the standard values are given for the dimensions of the sella turcica. This can be used for further analysis and reference standards for the Indian population. The length and diameter were statistically significant with different groups. The largest value was given in Class III.

Abstract:
Objective of the Study:
This study aimed to study the cephalometric features of Jordanian patients diagnosed with ß-thalassemia major and compare their dental development with their chronological age.
Subjects and Methods:
This was a case–control study. Lateral cephalometric radiographs of 27 thalassemia patients and controls (matched for age and ethnic origin) were analyzed and compared. Panoramic radiographs of 18 thalassemia patients were analyzed by the Demirjian system to assess their dental development and compare with their chronological age using t-test, with P < 0.05 set as the level of statistical significance.
Results:
Thalassemia patients exhibited a highly significant difference, compared to the controls, in sagittal relationship (ANB), mandibular plane inclination (MxP/MnP), anterior rotation of the maxilla (SN/Mxp), the ratio of posterior to anterior face height, and the upper incisors' distance to the maxillary base (P < 0.005). Prominent upper and lower lips (P < 0.001) and an acute nasolabial angle (P < 0.05) were evident in thalassemia patients compared to controls. Thalassemia patients had a delay in dental development with advancing age. Furthermore, there was a statistically significant correlation (P < 0.001) between the extent of this delay and chronological age, which indicates that the delay increases, as the patient gets older.
Conclusions:
Jordanian ß-thalassemia major patients have a Class II skeletal pattern, a prominent vertical growth direction of the mandible, protruded upper and lower lips, and proclined upper incisors. Furthermore, they have a delay in dental development with advancing age.

Abstract:
Objectives:
This study aimed to determine the position of the incisors and its effects on the profile, identify any possible gender differences, and compare the maxillary and mandibular anterior teeth positions between participants of short, average, and long faces.
Materials and Methods:
This study comprised cephalometric radiographs of 82 participants (male: 42, female: 40) with a mean age of 21.9 ± 2.8 years. The participants were divided into three groups: short face group: Frankfort mandibular plane angle (FMA) <25°, average face group: FMA ≥25°–<30°, and long face group: FMA ≥30°. Seven linear and eight angular measurements were measured and compared between the three groups.
Results:
No gender differences were found. The short face participants tend to have more proclined lower incisors, more protruded chin, more mandibular incisor display, and more retrusive upper lip position than the average and long face groups.
Conclusions:
The short face participants tend to have more proclined lower incisor, more protruded chin, a more mandibular incisor display, and more retrusive upper lip position than the average face and long face groups.

Abstract:
Maxillary hypoplasia is a constant feature among patients with cleft lip and palate (CLP), more pronounced in sagittal and transverse dimensions. Transverse maxillary deficiency is first addressed using various expansion appliances. Due to the excessive scarring on the palatal tissue, there is a high chance of relapse of the expansion achieved, and the challenge is to hold the results achieved. Palatal arch holding appliance is commonly used to prevent relapse and to maintain the achieved expansion. Management of difficult cases like bilateral CLP (BCLP) demands speeding up the pace of treatment by innovations in the appliance structures or treatment procedures to shorten the treatment period. This article attempts to address the reduction in the total treatment time in BCLP patients with a clinical modification of conventional treatment modality.

Abstract:
A major factor determining if early correction of an anterior crossbite will be stable is the achievement of a positive overbite. A clinician should avoid extracting maxillary teeth in Class III cases to contain the forward growth of the mandible. This article presents a case report of a pseudo Class III patient with anterior crossbite and maxillary blocked out canines, based on the best available evidence. We hereby propose a combination of rapid maxillary expansion with 2 × 4 appliance to provide a predictable and effective approach to managing pseudo Class III treatment with blocked out canines (moderate crowding) that were once considered implausible. A clinician should avoid extracting maxillary teeth in Class III cases to contain the forward growth of the mandible.

Abstract:
Objective:
This study aims to examine and correlate the position and orientation of the hyoid bone in Class I, Class II and Class III malocclusions.
Materials and Methods:
A total of 90 pretreatment digital lateral cephalograms were chosen in accordance with the established criteria and categorized into three groups, namely: Class I (n = 30), Class II (n = 37), and Class III (n = 23) malocclusions. The lateral cephalograms were traced and various linear and angular parameters such as MPH, H-NL, H-Go, H-Me, H-FH, H-C3, NSH, and H-NL were measured. The standard deviation and arithmetic mean values were computed for every measurement, after which independent t-test was conducted to study the variations between the skeletal classes of malocclusions.
Results:
The linear measurements of H-Me and H-C3 were found to be statistically significant. The angular measurements of SNA and ANB were also statistically significant and indicated the dissimilarities in the different classes of malocclusions. The anteroposterior position of hyoid bone was established, but the superoinferior positioning was found to be statistically insignificant.
Conclusion:
A significant difference occurs in the position and orientation of Hyoid Bone in relation to its surrounding structures in Class I, II, and III malocclusions. The hyoid bone is more anteriorly placed in Class III malocclusions than Class II which is more posteriorly placed. The superoinferior positioning of hyoid bone was found to be statistically insignificant in this study.

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
This case report shows the management of Angle's Class II division 1 Malocclusion with tooth size-arch length discrepancy of − 10 mm in maxillary arch and mandibular arches, proclined upper and lower anteriors, and crowding in relation to lower anteriors. Clinical evaluation revealed Class II dental and skeletal pattern, low mandibular plane angle, incompetent lips, increased overjet and overbite. Simultaneous intrusion and retraction of upper anterior teeth using Kalra Simultaneous Intrusion and Retraction arch was decided due unaesthetic excessive maxillary incisor showing at rest and to provide maximum space for the retraction of anterior teeth. Posttreatment changes were good and stable.

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.
