Abstract:
The success of repair in cleft lip and palate depends on the extent of disfigurement and the size of disfigurement which guides the surgical repair. With the popularization of nasoalveolar molding (NAM), the results of primary surgery in such patients have greatly improved due to the presurgical correction of the deformities leading to a better approximation of the tissues and hence reduced scarring. Thus, today, the knowledge of pre-surgical nasoalveolar molding should be a part of any orthodontist's armamentarium to enhance the results of surgical lip repair and reduce the extent of nasal deformity minimizing the need for revision surgeries. The current report describes the use of NAM in a newborn with unilateral cleft lip and palate and demonstrates the excellent results thus achieved after surgical repair.

Abstract:
For patients whose orthodontic problems are so severe that neither growth modification nor camouflage offers a solution, surgery to realign the jaws or reposition dentoalveolar segments is the only possible treatment option left. One indication for surgery is a malocclusion too severe for orthodontics alone. It is possible now to be at least semiquantitative about the limits of orthodontic treatment in the context of producing normal occlusion as the diagrams of the “envelope of discrepancy” indicate. In this case report, we have presented orthognathic treatment plan of an adult male patient with skeletal Class III malocclusion and anterior crossbite. Patient's malocclusion was decompensated by orthodontic treatment just before the surgery and then normal jaw relationship achieved by bilateral sagittal split ramus osteotomy. Patient's dental and facial profile was improved in a total of 18 months treatment duration. One-year follow-up showed stable results.

Abstract:
Objective:
The purpose of the present study was carried out to establish whether the vertical and horizontal growth patterns influence the rate of dental and skeletal maturation as compared to normal growth patterns.
Materials and Methods:
This study comprised sixty samples divided into three groups. Group I normal grower (control), Group II-vertical growers, and Group III-horizontal growers. Each sample was assessed for skeletal and dental age using cervical vertebrae maturation index (CVMI), skeletal maturity indicator stages and canine calcification stages, respectively. All data in the groups were analyzed by analysis of variance test. Subgroup data and comparisons were analyzed by Dunnett D-test and -test.
Results:
Results showed that dental maturation was delayed in horizontal growers as compared to vertical growers with = 0.00 and 0.044. There was nonsignificant difference in dental maturation of male and females with >0.05. The comparison of skeletal maturation by hand-wrist radiograph showed significant variation in Group III with delayed skeletal maturation of horizontal growers than control group with P < 0.05. Dunnett D-test showed main skeletal age by CVMI was significant with = 0.00 which indicates that skeletal age of Group III to be lower in all groups. Rest was nonsignificant.
Conclusion:
Individuals with horizontal growth pattern showed delayed dental maturation when compared to vertical growers.

Abstract:
Background:
Smiling is the evident component of facial attractiveness. Midline diastema is considered in some cultures as unattractive and as a malocclusion, especially in Western countries while it is considered as a sign of beauty in Africa and Middle-East.
Aim:
The aim of this study is to compare the smile attractiveness perception of dental and nondental students toward anterior diastemas and to determine whether all spaces in the esthetic zone are considered unattractive as midline diastema.
Materials and Methods:
This is a descriptive cross-sectional study conducted among 156 dental and pharmacy students from the University of Medical Sciences and Technology, Sudan, from December 2015 to January 2016. A self-administered questionnaire was distributed to the participants and it consisted of two parts: part one – related to gender, faculty, educational level, and questions about dental diastema, and part two – containing four modified pictures of a young female's smile modified by photoediting software to create different spaces between anterior teeth (midline, Simian, Frush and Fisher, and Lombardi diastema). Participants were asked to rank the pictures according to attractiveness from the most to the least attractive using visual analog scale. Comparison between variables was made by Chi-square test with P < 0.05.
Results:
Smile attractiveness from the most to the least attractive was Simian > Frush and Fisher > midline > Lombardi among both dental and pharmacy students. Gender and presence of diastema had no relation with the student's perception (P > 0.05). There was a significant statistical difference between dental and pharmacy students regarding Frush and Fisher diastema (P = 0.034). Most of the students with diastema felt shy when smiling.
Conclusions:
The location and width of diastema had an important role on the attractiveness perception of dental diastemas. Midline diastema was not a gap with the most negative perception

Abstract:
Ni-Ti open coil springs are often used to create space for alignment of malposed teeth. Predetermining the length of open coil spring required to open up the exact amount of space is rather difficult, and occasionally, the length of the open coil spring falls short to open up the entire space required. This article highlights the chairside intraoral method of reactivation of NiTi open coil spring with the use of crimpable hook without removing the base archwire.

Abstract:
Sterilization is a process by which an article, surface or medium is freed of all microorganisms either in vegetative or spore state. On a daily basis, the practicing dentist and his personal are at risk of being exposed to wide patients with blood borne diseases such as HIV/AIDS, hepatitis B, C, and airborne diseases such as tuberculosis. Infection can be directly transmitted by oral fluids, blood, contaminated instruments and surfaces, or through the respiratory system. Control of infection that spreads through various instruments and armamentarium used in the field of orthodontics and dentistry in general is of utmost importance as a preventive measure for cross infection. Considering the fact that the rate at which newer strains evolve with time and older strains develop resistance, it has become a constant challenge through time and in the years to come. This article tells about various methods of sterilization by focusing on the guidelines for an effective and efficient orthodontic practice.

Abstract:
Introduction:
Deep bite correction in patients with convex profile and increased maxillary incisor visibility, and normal or increased vertical dimension necessitates the intrusion of maxillary incisors. Intrusion arches or miniscrews are commonly used for this purpose. The current study compares one of the prefabricated intrusion arches, the Connecticut intrusion arch (CIA), and the temporary anchorage devices (TADs) in their effectiveness for orthodontic intrusion.
Materials and Methods:
The present prospective study was done on 24 patients in the age group of 15–25 years undergoing fixed orthodontic treatment. In Group I, TADs were placed for intrusion while, in Group II, CIA was placed. Anchorage was reinforced in Group II using transpalatal arch. A paired t-test or a Wilcoxon signed-rank test was performed for the assessment of treatment changes within the groups, and an independent t-test or a Mann–Whitney U-test evaluated change between the groups.
Results:
Both TADs and CIA can bring about significant amount of true incisor intrusion with resultant decrease in incisor visibility. However, in the TAD group, in addition to intrusion, the incisors also proclined by 0.67 mm, but in CIA group, incisors retracted by 0.33 mm. There were nonsignificant mesial drift and significant extrusive movement of the maxillary first molars in the CIA group. The rate and amount of intrusion was greater in the TAD group.
Conclusions:
Both TADs and CIA can be effectively used for incisor intrusion which was, however, faster and greater in TAD group. Both the methods bring about associated unwanted tooth movements as well.

Abstract:
Impacted canine teeth are problems frequently encountered in dental practice. Maxillary canine teeth are the most commonly impacted teeth next to third molars. Incidence of palatal impaction is greater than labial impaction. Many etiological factors attributed for canine impaction. Timely diagnosis and interception provide a better management of impacted canine. There are various orthodontic auxiliaries used for disimpaction of canine. Ballista spring is one of the simplified orthodontic auxiliary spring developed by Harry Jacoby used for repositioning impacted teeth. It delivers light force, excellent biomechanics, simplicity of the design, patient comfort, and esthetics. This case report presents a case of orthodontic repositioning of palatally impacted canine in a 15-year-old using ballista's spring.

Abstract:
Cleft lip and palate (CLP) is the most commonly occurring congenital facial anomaly, in which Bilateral CLP is the least common among the different types of CLP. CLP correction requires a proper diagnosis and stage-wise treatment planning with a multidisciplinary approach which involves orthodontic and surgical correction of dental malocclusion and skeletal discrepancies, respectively. This case report emphasizes the need for multidisciplinary treatment which includes orthodontic treatment, orthognathic surgery, secondary lip revision and rhinoplasty performed in an 8-year-old patient with bilateral CLP to achieve a balanced and pleasing profile with good functional occlusion. The multidisciplinary approach performed by the orthodontists and oral surgeons brought stupendous results and showed good retention at 2-year posttreatment.

Abstract:
Introduction and Objectives:
The extraction versus nonextraction controversy is the oldest as well as the most enduring controversy and still remains a topic of debate in the field of orthodontics. The “American Board of Orthodontics” (ABO-1998) introduced an index called the objective grading system (OGS) which evaluates posttreatment dental casts and panoramic radiographs. It assesses the final occlusion in first, second, and third orders according to eight different occlusal components. The aim of the present study was to evaluate the treatment outcome of extraction and nonextraction cases in borderline cases by ABO-OGS system.
Materials and Methods: .
Forty borderline orthodontic patients with Angle's Class I malocclusion with an age group of 13–20 years were selected and equally divided into two groups: twenty patients were treated by extraction of all first premolars and twenty patients with a nonextraction treatment protocol. MBT 0.022” slot prescription was used for all forty patients. With the aid of an ABO measuring gauge and panoramic radiographs, the total OGS scores between the two groups were calculated and compared using Student's t-test.
Results:
The mean OGS scores were significantly less negative in the extraction group (−22.0 ± 2.29) as compared to the nonextraction group (−26.80 ± 5.18, P < 0.005).
Conclusion:
According to this study, in the borderline cases, the final occlusion and radiographical characteristics were more acceptable in the patients treated with extraction than the nonextraction patients.

Abstract:
Introduction:
To analyze the skeletal features of patients with maxillary canine impaction.
Materials and Methods:
Pretreatment lateral cephalograms of 30 patients in buccally displaced canine group (BDCG), 15 in palatally displaced canine group (PDCG), 30 in impacted canine group (ICG), and 50 in control reference sample (control group [CG]) were used to analyze the selected dentoskeletal characteristics. One-way analysis of variance was used to identify the differences in angles among the four groups (BDCG, PDCG, ICG, and CG). The differences in the relative distribution among the groups were tested by Pearson's Chi-square test. Independent samples t-test was used to test the significance of differences between the two groups.
Results:
In BDCG, retrognathic maxilla, tip up maxilla, retrognathic mandible, skeletal Class II, and horizontal growth pattern were the significant factors. In PDCG, skeletal Class II and hypodivergent were significant factors. In ICG, retrognathic maxilla, retrognathic mandible, hypodivergent relationships are poorly significant factors. The nasolabial angle and Steiner's S line were insignificant in all groups except the ICG where acute nasolabial angle is poorly significant.
Conclusion:
When compared to controls, canine impaction(s) revealed a trend toward retrognathic maxilla, retrognathic mandible, skeletal Class II, and hypodivergent skeletal relationship.

Abstract:
Aim:
The present study was aimed to investigate the variation of soft palate morphology and Need's ratio in various sagittal skeletal malocclusions.
Materials and Methods:
The study was conducted on 300 individuals (aged 15–25 years) who presented to the department of orthodontics for orthodontic treatment. The participants were divided into skeletal Class I, II, and III based on ANB angle on the lateral cephalogram. The soft palate morphology was examined and individuals were grouped into six types. The Need's ratio was calculated for all the participants by division of pharyngeal depth by soft palate length. The results were then subjected to statistical analysis to find the association between morphological variants of soft palate and skeletal malocclusions.
Results:
The most common type of soft palate was leaf shaped and the least common was S shaped. Leaf-shaped soft palate was the most common in males and rat tail-shaped soft palate was common in females. Individuals with skeletal Class I malocclusion were most frequently found to have leaf-shaped soft palate, skeletal Class II malocclusion had rat tail type, and skeletal Class III had leaf shape and crooked shape in equal proportions. Need's ratio was maximum in skeletal Class III and minimum in Class II malocclusions.
Conclusions:
There was a significant correlation between the variants of soft palate and the types of skeletal malocclusion in North Indian individuals. The knowledge of morphological variants of soft palate helps the clinician in etiological study of obstructive sleep apnea syndrome, snoring, and other conditions.

Abstract:
Objective:
The objective of this study is to evaluate and compare the level of receptor activator of nuclear kappa B ligand (RANKL) and osteoprotegerin (OPG) in gingival crevicular fluid (GCF) during canine retraction with nickel-titanium (NiTi) coil spring and elastomeric chain.
Materials and Methods:
Ten patients between the ages of 13–17 years requiring canine distalization after first premolar extraction were selected. NiTi coil spring was placed on one side and elastomeric chain on the contralateral side. GCF sampling was done at baseline, 1 h, 24 h, 168 h, 1 month from the distal site of the test teeth after the application of compressive force. RANKL and OPG concentration were detected by enzyme-linked immunosorbent assay.
Results:
In the NiTi coil spring side, the RANKL levels in GCF increased and OPG levels decreased in a time-dependent manner. Increase in RANKL and decrease in OPG were significant when compared with the baseline. In the elastomeric chain side, the RANKL levels were significantly higher and the OPG levels significantly lower at 24 h, the RANKL levels showed a significant decrease and OPG levels showed a significant increase from 24 h to 1 month time intervals. The RANKL and OPG levels in GCF when compared individually to the NiTi coil spring and elastomeric chain showed a significant difference at 24 h, 168 h, and 1 month after initiation of compressive force.
Conclusion:
The result suggests that RANKL and OPG expression during orthodontic tooth movement varies at different time intervals and according to the type of force delivery system.

Abstract:
In orthodontic treatment, there is difficulty in finishing stage in teeth that need uprighting to obtain root parallelism. Horizontal uprighting spring is used to upright teeth (clockwise or counterclockwise) to avoid uptighting problems in the late finishing stage such as rebonding brackets and to overcome the lack of vertical slot in the bracket. Horizontal uprighting spring is fabricated in the 0.012-inch stainless steel wire. Moreover, the type of tooth movement and the moment/force ratio can be determined by the spring length and hooking point.
