Abstract:
Transverse maxillomandibular discrepancies are a major component of several malocclusions. Transverse maxillary discrepancies are routinely corrected in growing patients with appliances that separate the median palatal and associated maxillary sutures. This type of rapid palatal expansion (RPE) is not feasible in adults, however, because of the increasing resistance of the sutures. Surgically assisted RPE is an alternative method that reduces the resistance of the closed midpalatal suture to correct maxillary constriction in an adult. It allows clinicians to achieve effective maxillary expansion in a skeletally mature patient.

Abstract:
Background:
The function of many orthodontic indices is to assess occlusion in patients born with a cleft. The aim of this study was to assess the intra- and interexaminer reliability for the 5-year-olds' (5YO) index, the GOSLON Yardstick index, and the modified Huddart/Bodenham (MHB) index in dental casts of children with complete unilateral cleft lip and palate (UCLP); a further aim is to compare the indices to each other.
Methods:
Forty dental casts from 5-year-old nonsyndromic patients with complete UCLP who had undergone primary surgery at Skåne University Hospital in Malmö, Sweden, were examined by two examiners: one orthodontic specialist and one general dentist.
Results:
Intraexaminer reliability for 5YO and MHB had a substantial (κ: 0.61–0.80) to almost perfect agreement ( κ: 0.81–1.00) and GOSLON Yardstick moderate (κ: 0.41–0.60) to almost perfect agreement. Grouped teeth or single-tooth MHB had an almost perfect agreement for both examiners. Interexaminer reliability for 5YO had a moderate agreement, whereas GOSLON Yardstick and MHB had a fair agreement (κ: 0.21–0.40). Grouped teeth or single-tooth MHB had an almost perfect agreement.
Conclusions:
The 5YO index illustrates the occlusion and has a high degree of reliability for an experienced orthodontist. The GOSLON Yardstick also illustrates the occlusion, but reliability between assessments is lower. MHB index can be used with a high degree of reliability when categorized as grouped or single tooth, but the judgment of total occlusion is more uncertain.

Abstract:
Background:
Arch dimensions are very important to clinicians in orthodontics, pedodontics, prosthodontics, as well as to anthropologist. The dimensions include arch widths, arch length, and intra-alveolar width which assist in establishing proper diagnosis and treatment planning.
Aims:
This study aims to determine the arch dimensions in Qatari sample with different malocclusions, compare the results obtained with other previous studies and also compare the result between the different Angle's malocclusions classes.
Materials and Methods:
The sample consisted of 90 pairs of pretreatment orthodontic study casts selected from patients attending the orthodontic clinic. The sample was classified into three groups according to Angle's Classification as follows: Class I, Class, II, and Class III malocclusion and each group consisted of 30 pairs. The age range was between 13 and 20 years old. The intercanine width, inter-premolar width, intermolar width, and intra-alveolar width measurements were made in each dental cast using an electronic digital caliper. Independent t-test was performed for comparative analysis.
Results:
Descriptive statistics were presented for the three Angle's classifications. No significant difference was noted between the maxillary variables in Class I and Class III. Statistically significant difference was noticed in maxillary variables in Class II (intermolar II and inter-premolar I and II). Furthermore, significant differences were revealed in mandibular intermolar I and II, inter-premolar II, and inter-alveolar between Class III and Class I and also between Class III and Class II malocclusions. Class III malocclusion showed wider arch dimensions than that in Class I and Class II.
Conclusions:
The result of the present study is important to the orthodontist, pedodontist, and also to the prosthodontist and anthropologist.

Abstract:
Functional orthopedic appliances are mostly used to treat Class II malocclusion originated from mandibular retrusion. Removable or fixed functional appliances are available to advance the mandible. Fixed appliances can be treated in tandem with multibarcket therapy, thus making it a single-phase treatment. The major disadvantage of fixed functional appliances is proclination of lower anterior teeth. To reduce this proclination, miniplates or miniimplants are being used; negative torque is added to the lower incisors. Despite these additions, the proclination could not be eliminated but minimized. This case report documents the successful treatment of skeletal Class II in late stages of puberty using forsus fatigue resistance appliance with soldered hooks placed distal to the lower canines.

Abstract:
Orthodontic patients avoid many types of food, particularly fruits, raw vegetables, and other hard and tough foods, as they cannot chew these properly because of pressure sensitivity of the teeth in the initial 3–5 days period after routine. As a result, such individuals consume significantly less proteins and other key nutrients, fiber, calcium, nonhem iron, and some vitamins. This article presents an overview of the relationship between diet and orthodontic treatment. The nutritional guidelines to obtain good oral and general health in orthodontic patients are discussed.

Abstract:
Orthodontist must be aware of the impact of bleeding disorders on the management of orthodontic treatment. Initial recognition of a bleeding disorder, which may indicate the presence of a systemic pathologic process, may occur in dental practice. Patients should be queried about any previous unusual bleeding episode after surgery or injury, spontaneous bleeding, and easy or frequent bruising. The purpose of this paper is to review bleeding disorders and their effects on the delivery of orthodontic treatment.

Abstract:
Evidence-based dentistry (EBD) was developed to help dental care professionals in incorporating the current, valid, and bias-free research into their clinical practice. It is equally important to review and critically appraise the evidence before its adoption into clinical decision-making. In orthodontics, as there are emerging innumerable appliances, materials, and treatment approaches, there is an urgent need to conduct new trials to determine their effectiveness. Recently, randomized controlled trials (RCTs) are considered as the most powerful and strongest research design for the comparison of various treatment interventions. This article gives a brief overview about EBD and RCTs and their importance in the field of orthodontics.

Introduction:
Bonding of orthodontic attachments with acid etching is the most commonly used orthodontic procedure. However, there are certain limitations with acid etching procedure like/moisture contamination, etching time, the concentration of adhesive, etc., Moisture insensitive primers (MIPs) were introduced to overcome these limitations.
Objectives:
The aim of this study is to compare the shear bond strength of orthodontic brackets bonded with a MIP (Transbond MIP, 3M Unitek) against a conventional primer (Transbond XT, 3M Unitek) when contaminated with saliva – in vitro study.
Methodology:
Sixty maxillary premolars extracted for orthodontic purpose or due to periodontal involvement with sound buccal surfaces were collected, cleaned thoroughly, and stored in 0.1% (wt/vol) thymol at room temperature for 2 weeks. Following materials were used: Transbond XT Light cure adhesive (3M unitek), Transbond XT primer (3m unitek), Transbond MIP primer (3M unitek), and Metal brackets (3M unitek). A commercially available artificial saliva (AQWET, CIPLA) was used for contamination purpose. Ivoclarbluephase N LED light curing unit were used for curing purpose.
Results:
Mean bond strength was well above the clinically acceptable bond strength values indicating the use of these hydrophilic bonding materials in contaminated environments (8.5 Mpa for Transbond XT and 9.25 Mpa for Transbond MIP). On comparison of bond strengths of MIP and XT when contaminated with saliva, statistically significant values were obtained with contamination with saliva after primer application. There was a statistically significant increase in the bond strength after primer application (P = 0.233) and before and after primer application (P = 0.027*). Transbond MIP can be used to achieve adequate bond strength in saliva contaminated condition.
Conclusion:
Under dry condition, the shear bond strength of conventional primer (TRANSBOND XT) was significantly increased when compared to MIP. Under wet conditions MIP (TRANSBOND MIP) showed the highest shear bond strength and hence can be considered as a material of choice in wet conditions.

Abstract:
Background:
Regularly used parameters for anteroposterior assessment of jaw relationships are ANB angle and Wits appraisal, and recently, beta angle, Yen angle, and W angle are introduced. ANB angle depends on the cranial landmarks and is affected by various factors and often can be misleading. The Wits appraisal does not depend on cranial landmarks, but still has the problem of correctly identifying the functional occlusal plane, which can sometimes be impossible. To overcome these problems, a new measurement, beta angle, was developed at Tufts University. The present study was carried out on Maharashtra population to derive norms of beta angle.
Materials and Methods:
For selection of sample, the lateral cephalograms were selected from the available patient's records, and the sample was divided into three groups based on the ANB angle, Wits appraisal, and profile.
Conclusion:
The norms of beta angle are between 28.5° and 36.5° in skeletal Class I pattern, <28.5° in skeletal Class II pattern, and >36.5° in skeletal Class III pattern.

Background:
Facial patterns or biotypes have been known to influence the treatment plan of orthodontic patients and analyze the facial patterns described by Ricketts. Determining the facial type is extremely important for orthodontic diagnosis and planning since the muscular and skeletal configuration of each facial type responds differently to the orthodontic treatment.
Materials and Methods:
A sample of 100 individuals was recruited by multistage sampling from three schools in Ikeja local government, Lagos State. Those aged between 12 and 16 years who met the inclusion criteria were enrolled in the study after obtaining informed consent and assent from the parents and participants. Lateral cephalometric radiographs were taken for all participants, and the final sample after analysis of the radiographs was 84. The error of the cephalometric method was assessed using the intraclass correlation coefficient. Facial axis angle (Ptm-Gn/Ba-N) was used to classify the facial pattern into brachyfacial (<87°), mesofacial (87°–93°), and dolichofacial (>93°)
Results:
Out of the 84 participants, 60 (71.4%) had mesofacial facial pattern which consisted of 27 (32.1%) males and 33 (39.3%) females. 10 (11.9%) had brachyfacial pattern out of which 9 (10.7%) were male and 1 (1.2%) was a female. This difference between the males and females in the brachyfacial pattern was statistically significant with a P value of 0.014 (P ≤ 0.05). 14 (16.67%) participants had dolichofacial pattern with 5 (6.0%) males and 9 (10.7%) females.
Conclusion:
The mesofacial pattern had the highest frequency among the facial pattern types studied in this Nigerian population and was found to be more predominant among females. The brachyfacial pattern was seen more frequently in males while the dolichofacial pattern was more prevalent among females. The facial pattern assessment should guide the orthodontist in the use of appropriate mechanics to achieve an overall balanced occlusion and facial profile following orthodontic treatment.

Abstract:
Periodontally accelerated osteogenic orthodontics (PAOO) is a combination of a selective decortication facilitated orthodontic technique and alveolar augmentation. With this technique, one is no longer at the mercy of the preexisting alveolar volume, and teeth can be moved two to three times further than required for traditional orthodontic therapy. It is used to treat moderate-to-severe malocclusions in both adolescents and adults. PAOO technique increases alveolar volume which can provide a more intact periodontium, inturn decreases need for extractions, increases a degree of facial reshaping. This technique also increases the bony support for both the teeth and the overlying soft tissues. Here is a case report which highlights the above-mentioned uses with PAOO technique in a severe periodontally compromised Class II division1 malocclusion patient treated with nonextraction line of orthodontic treatment.

Abstract:
Maintaining the achieved occlusion following the orthodontic treatment is the most difficult task of the entire treatment process. Relapses are common in noncompliant patients and in some cases despite the patient following the protocol. There are various factors for the relapse after the orthodontic treatment. The relapsed malocclusions can be corrected by simple procedures such as composite buttons. They are economical and esthetic considering the relapsed space. A 27-year-old female patient presented to our orthodontic department with the chief complaint of mild anterior spacing with midline diastema and anterior crossbite in relation to 21, after treatment with fixed appliance therapy. The patient was treated with composite buttons, and satisfactory results were obtained. Composite buttons are an alternate treatment line for mild relapsed cases in patients who are not willing to undergo the fixed appliance therapy again.

Abstract:
The prediction of orthognathic treatment is an important part of treatment planning. The manual method of prediction tracing by Epker and Fish had been the gold standard in planning for orthognathic cases. Because it was time-consuming, hence computerized methods gained the popularity. A 19-year-old boy reported with a chief complaint of forwardly placed lower jaw and poor smile for the past 2 years. Examination revealed the mandibular prognathism, obtuse nasolabial angle, posterior cross bite with reverse overjet of 1 mm–0.5 mm of overbite, and bilateral Class III molar and canine relation. There was also the deviation of 1.5 mm midline to left present. On the basis of findings, a diagnosis of mandibular prognathism was made. Treatment planning included an orthognathic surgery (Bilateral sagittal split osteotomy) for the mandibular setback. For the surgical procedure, both manual and computerized methods of prediction were done. Both tracing methods result was same and recommended the mandibular setback of 5 mm.

Abstract:
This case report describes the orthodontic treatment of an 18-year-old male patient who presented with straight profile, tongue thrust habit, proclined upper incisors, generalized spacing in the upper and lower arches, Katz Class II premolar relation unilaterally, and Class II canine relation unilaterally with increased overjet and overbite. A butterfly system was used for the treatment combined with frictionless biomechanics in the initial stage of the treatment followed by continuous arch mechanics in the later part of the treatment. A tongued crib was used to stop the tongue thrust habit along with one elastic swallow exercise. Micro-implant anchorage was used unilaterally in the upper arch for retraction of the entire segment and correction of the unilateral Class II canine and premolar relationship. To avoid a dished-in profile, a nonextraction treatment was executed. Final correction of distally tipped canines was achieved using conventional Begg's uprighting auxiliaries in the vertical slots of the butterfly system in the finishing stage. The case was finished using bite-settling elastics. The total treatment time was 1 year and 2 months. Esthetic and functional goals were achieved satisfactorily with proper selection of biomechanics.

Abstract:
Since 1930s Class II malocclusion benefits from functional appliances. These appliances alter the arrangement of various muscle groups to correct the position of mandible to grow out of the skeletal disharmony. These appliances have been broadly divided into removable and fixed functional appliances. Fixed functional appliances also known as “noncompliant Class II correctors” have gained significant ground in the last few years. With them in use, the treatment duration is reduced by 6 months. They are divided into rigid, flexible, and hybrid appliances. Rigid fixed functional appliances restrict the mandibular movements and flexible fixed functional appliances have frequency of breakage to a greater extent. To overcome these drawbacks, hybrid fixed functional (HFF) appliances have come into play. HFF appliances offer the advantages of previous ones, thus eliminating their pitfall. Recent advances have also lead to the improvisation with the use of HFF appliances. This review article provides the gist of different HFF appliances till date with their considerations in use, mode of action, biomechanical effects, and advances in this field.

Abstract:
Background:
Retention is considered as an important phase at the end of any active orthodontic tooth movement.
Aims:
The purposes of this study were to compare compliance between Hawley retainer (HR) and vacuum formed retainers (VFRs) and to detect the reasons for noncompliance.
Materials and Methods:
Questionnaires were distributed to those who had an orthodontic treatment and currently have experience with the orthodontic retainer. Items included demographic information and questions pertaining to treatment satisfaction, perceived responsibility for retention, type of retainer prescribed, Likert scale to detect the reasons for discontinuing use of retainers, and relapse. Chi-square and t-test were used to compare the data.
Results:
Out of the 150 questionnaires distributed, 98 returned and seven were excluded from the study. The compliant groups were 40, whereas the noncompliant group were 51. Sixty-four (70.3%) of the participants were using HR, whereas 27 (29.7%) were using VFRs retainer. Seventeen percent (Hawley) and 15% (VFRs) of the participants who did not comply reported that they had lost their retainer. For both retainers, those participants who did not comply, the majority agreed that they do not wear their retainer because it affects their eating (84.3%), speech (56.9%), comfort (47.1%), and breath odour (43.1%). A statistically significant difference in compliance levels in relation to the length of time since debond was also found (P < 001).
Conclusions:
The participants were more compliant with Hawley's than VFRs retainers and a significant difference in compliance levels in relation to the length of time since debond was found.

Abstract:
Aim:
The purpose of this investigation was to establish an equation for the prediction of the size of unerupted canines and first and second premolars in a Qatari population.
Materials and Methods:
In this study, dental casts of 100 Qataris (50 males and 50 females) were selected. The participants' age ranged from 15 to 20 years. The width of all permanent teeth with the exception of second and third molars was measured. The data were subjected to Student's t-test and regression analysis.
Results:
The results indicated that 15%, 25%, and 35% confidence levels were more accurate determinants of the unerupted canines and premolars than the commonly used 75% level of Moyers when both sexes were combined. The multiple regression equations revealed different confidence levels for males and females. Tanaka and Johnston's equations overestimate the predicted tooth width of the unerupted canine and first and second premolars.
Conclusions:
Three levels of confidence were found to be more accurate in the maxillary arch and two in the mandibular arch when compared to the commonly used 75% in Moyers' table when both sexes were combined. Therefore, three new equations for maxillary and mandibular arches are proposed to predict the size of unerupted canine and first and second premolar teeth for Qatari males and females and for both sexes combined.

Abstract:
Background:
Impacted upper central incisors substantially affect esthetics, function, and the self-esteem of patients. This retrospective multicenter study was designed to assess and compare the demographic and radiographic features and treatment findings for patients with impacted upper central incisors in three different countries.
Materials and Methods:
Diagnostic and treatment records, panoramic radiographs, and lateral cephalograms were retrieved for 74 (32 female) patients (11.24 ± 2.9 years old), with impacted upper central incisors from the USA, Germany, and Colombia, according to the preset eligibility criteria. Sagittal and vertical angulation and location of the upper impacted central incisors, type of radiographic skeletal malocclusion, surgical procedures, and duration of treatment were investigated.
Results:
Statistically significant differences between the three groups were found for age (P = 0.003), duration of treatment (P = 0.001), and location of the impacted upper central incisors (P = 0.015). The angulation was significantly bigger for the impacted central incisors compared to the respective normal incisors (P < 0.0001). The age of the patients did not influence the treatment time. The regression model showed that higher height of impaction was associated with a closed surgical procedure (P = 0.046).
Conclusions:
Patients with impacted incisor treated in three different centers showed differences in terms of age, gender, treatment time, and type of surgical treatment. The surgical access with closed surgery has a direct relationship with a more apical location of the impacted incisor.

Abstract:
Replacement of missing teeth in growing children is one of the challenges an orthodontist encounters. Removable partial denture or resin-bonded fixed denture can be considered as replacement options, but they promote alveolar bone loss due to lack of alveolar loading. Removable denture is undesirable as adolescents are self-conscious in revealing the edentulous space while eating. Resin-bonded fixed denture compromise alveolar and gingival contours. Dental implants are not placed in growing children due to remaining growth. Orthodontic miniscrews can be efficiently used for interim restoration before skeletal growth. The current article presents a case report of miniscrew-assisted interim tooth pontic.
