Between different arch dimension maxillary arch widths were found to have significantly smaller in Class I crowded malocclusion compared with Normal Class I occlusion.</p> <p><strong>Conclusion</strong>: In conclusion, the hypothesis was partially rejected by the finding of the study.</p> <p>Ban J Orthod &amp; Dentofac Orthop, April 2017; Vol-7 (1-2), P.1-5</p> Rashed Md Golam Rabbani, Md Abdul Muttalib Malik, Md Zakir Hossain ##submission.copyrightStatement## Wed, 23 Oct 2019 07:26:02 +0000 Dental Arch Width in Children and Relationship to their Oral Habits <p><strong>Aim</strong>: Objectives: To analyze variations in dental arch width in relation to oral habits. &nbsp;</p> <p><strong>Materials and</strong> <strong>Methods</strong> : Cross sectional&nbsp; study was carried out Department of Orthodontics &amp; Dentofacial Orthopedics of Dhaka Dental College &amp; Hospital, Dhaka with a total number of 600 primary school children of 3-6 years ages of Bangladeshi population.</p> <p><strong>Results</strong>: This study was a cross sectional study conducted among the 600 children with 3-6 years old prima- ry school children of Bangladeshi population. According to present study, bottle feeding causes significant reduction in maxillary intercanine width and mouth breathers show significant reduction of both arches.</p> <p><strong>Conclusion</strong>: It was observed that the children who had used a bottle had a significant reduction in maxillary intercanine width. Breathing through mouth appeared to be associated with a reduction in the size of both arches. This was more significant in the maxillary intercanine , mandibular&nbsp; intercanine and mandibular molar widths. Therefore to prevent malocclusions, the public should be informed of the harm caused by certain oral habits, the benefits of breast-feeding, and the need to correct bad habits at early life.</p> <p>Ban J Orthod &amp; Dentofac Orthop, April 2016; Vol-7 (1-2), P.6-11</p> Kohinur Akther, Md Zakir Hossain ##submission.copyrightStatement## Wed, 23 Oct 2019 00:00:00 +0000 The effects of orthodontic tooth movement in endodontically treated teeth <p>There are no relevant contraindications to orthodontic treatment of previously endodontically treated teeth, considering the quality of the obturated teeth, the health of the periodontal membrane, along with careful application of orthodontic force. Although, there is usually some degree of reversible or transient pulpal inflammation&nbsp; even&nbsp; in&nbsp; healthy&nbsp; teeth&nbsp; during&nbsp; orthodontic&nbsp; treatment,&nbsp; application&nbsp; of&nbsp; light&nbsp; and&nbsp; intermittent orthodontic force will reduce the risks provided sufficient time is given to allow proper repair of the dental tissue.&nbsp; However,&nbsp; there&nbsp; may&nbsp; be&nbsp; a&nbsp; few&nbsp; hazards&nbsp; associated&nbsp; with&nbsp; the&nbsp; treatment&nbsp; of&nbsp; endodontically&nbsp; involved teeth, some of which mainly include root resorption and ankylosis. This article will show some cases of teeth which had undergone&nbsp; root canal treatment prior to orthodontic management and further observed whether orthodontic tooth movement had caused any resorption in the root filled teeth.&nbsp; Root canal treated teeth can be moved orthodontically to the same extent as vital teeth, providing, a controlled force applica- tion to avoid risk of inflammatory root resorption.</p> <p>Ban J Orthod &amp; Dentofac Orthop, April 2017; Vol-7 (1-2), P.12-15</p> Sabrina Haque, Mehreen Zakir ##submission.copyrightStatement## Wed, 23 Oct 2019 07:26:54 +0000 Oral Hygiene status among patients treated with fixed orthodontic appliance in the Department of Orthodontics in BSMMU <p><strong>Background</strong>: Oral hygiene maintenance is difficult for patients who are receiving fixed orthodontic treatment.</p> <p><strong>Objective</strong>: The aim of the study was to find out deterioration of oral hygiene status during treatment of fixed orthodontic appliances in the Department of Orthodontics in BSMMU.</p> <p><strong>Methodology</strong>: This cross sectional study was carried out in the Department of Orthodontics at Bang- &nbsp;abandhu Sheikh Mujib Medical University, Dhaka from July 2013 to July 2014. All the patients taking treatment with fixed orthodontic appliances for more than 6 months were included as study population. During treatment in the OPD all the information of the patients’ oral hygiene maintenance like brush- &nbsp;ing, dental floss use, use of mouthwash, and history of sugar consumption, taking sticky food were recorded.&nbsp; The&nbsp; Orthodontic&nbsp; Plaque&nbsp; Index&nbsp; (OPI)&nbsp; was&nbsp; calculated&nbsp; and&nbsp; recorded.&nbsp; In&nbsp; addition&nbsp; to&nbsp; that frequency of brushing, type of tooth brush, technique of brushing and inter dental brush were also considered.</p> <p><strong>Result</strong>: A total number of 100 patients were studied. Mean OPI was 81.78 (22.97). Mean value of OPI was 86.35 (13.27) among patients who brushed their teeth once a day but it was decreased gradually as the&nbsp; patients&nbsp; increased&nbsp; frequency&nbsp; of&nbsp; toothbrush&nbsp; use&nbsp; per&nbsp; day&nbsp; and &nbsp;became&nbsp; 85.74&nbsp; (±26.12)&nbsp; among&nbsp; the patients who brushed their teeth thrice a day. Mean value of OPI was 81.98 (±23.27) who did not use dental floss and 75.00 (±7.00) who used dental floss once a day. Mean value of OPI was 84.65 (±23.10) who used inter dental brush irregularly but 35.00 (±0.00) who used it thrice a day. Mean value of OPI was 85.70 (±22.43) who did not use mouth wash whereas it reduced to 46.00 (±0.00) among them who used mouth wash thrice a day. &nbsp;Conclusion: All the indexes of oral hygiene are increased in patients treated with fixed orthodontic appliances in the Department of Orthodontics in BSMMU.</p> <p>Ban J Orthod &amp; Dentofac Orthop, April 2017; Vol-7 (1-2), P.16-19</p> Md Ali Kawsar, Marina Akhtar, Md Ahsan Habib, Zafrina Islam, Md Nurul Islam ##submission.copyrightStatement## Wed, 23 Oct 2019 07:27:32 +0000 Bond Strength Comparison of Orthodontic Bonding Systems: A Systematic Review <p>As a means of regular practice in orthodontics and aesthetic dentistry, resin based adhesive systems are being used exclusively. Keeping up with the ever-increasing demand for aesthetic dental treatment all over the world, newer and more improved adhesive systems have been developed. However, regarding the comparison as to which bonding system performs better in clinical perspective, there is lack of existing scientific review articles. In this review, we tend to explore the conventional etch and rinse bonding system and the self-etch primer bonding system. The different tests to assess and compare bond strength between these two types of adhesives from various bibliography are discussed. The results of shear bond strength test, adhesive remnant index (ARI), enamel-adhesive interface using scanning electron microscope (SEM) and the effect of saliva contamination and time are discussed. Interestingly, each system has its strengths and weaknesses. In shear bond strength, self-etch bonding systems clearly exhibits less strength than conventional bonding systems. Resin tags into enamel surface are shorter in self-etch primer adhesives which results from milder etching to enamel compared to the conventional aid-etch and rinse adhesives. Contrarily, the irreversible changes to enamel surface is more aggressive in conventional acid-etching which states that self-etching systems are better according to the principles of minimal intervention dentistry.</p> <p>Ban J Orthod &amp; Dentofac Orthop, April 2017; Vol-7 (1-2), P.20-26</p> Tubayesha Hassan, MH Sattar ##submission.copyrightStatement## Wed, 23 Oct 2019 07:27:45 +0000 A study on Arch Widths of Bangladeshi Adult Subjects with Class II -2 malocclusion compared to Normal Occlusion <p><strong>Aim</strong>: To evaluate the transverse discrepancy in Class II div 2 malocclusion and normal occlusion. Also to test the hypothesis that models with class II div 2 malocclusions may have mean maxillary arch widths significantly smaller than those with normal occlusion. Thus the proposed study will generate interest among the orthodontists for further study over the transverse discrepancy of our patients and guide them to establish effective treatment strategy and their management.</p> <p><strong>Materials and Methods</strong> : Cross sectional comparative study was carried out Department of Orthodontics &amp; Dentofacial Orthopedics of Dhaka Dental College &amp; Hospital, Dhaka with 100 sample was included in this study.</p> <p><strong>Results</strong>: Maxillary intercanine, interfirst premolar and interfirst molar widths between normal occlusions and class II div 2 malocclusions were statistically significant.Maxillary measurements of class II div 2 malocclusion were smaller than normal occlusion. Mandibular intercanine, interfirst premolar and interfirst molar widths between Class II div 2 malocclusion and normal occlusions were statistically significant.</p> <p><strong>Conclusion</strong>: This study helps in determining possible differences in the dental arch widths of Bangladeshi people in Class II-2 adults compared to adults with normal occlusion may be an important aid in further understanding of dentoalveolar characteristics of these conditions, as well as improving their management.</p> <p>Ban J Orthod &amp; Dentofac Orthop, April 2017; Vol-7 (1-2), P.27-30</p> Md Masud Rana, Fazlay Rabbani, Deloar Hosen ##submission.copyrightStatement## Wed, 23 Oct 2019 07:27:56 +0000 Impacted Maxillary Central Incisors: Surgical Exposure and Orthodontic Treatment: A Case Report <p>Maxillary central incisor impactions occur infrequently.Their origins include various local causes, such as odontoma, supernumerary teeth, and space loss.
