It is generally divided into cleft lip (CL), cleft palate (CP) and cleft lip with cleft palate (CLP). The objective of the study was to evaluate distribution of patterns of orofacial clefts according to sex and laterality; predisposing factors and other congenital anomalies associated with cleft lip and/or palate.</p> <p><strong>Materials &amp; Method: </strong>A cross-sectional descriptive type of study was carried out using in 268 patients having cleft lip and/or palate. Types of clefts, predominance of sex and laterality, familial history, associated anomalies and drug and disease history of mother were recorded.</p> <p><strong>Result: </strong>The results revealed 23.51% CL, 54.85% CLP and 21.64% CP. There were 58.21% males and 41.79% females. Positive family history of cleft was present in 28.0% and associated anomalies were observed in 3.7% of the cleft subjects. Mothers of 6.0% of the total patients were exposed to teratogenic agents during first trimester of pregnancy.</p> <p><strong>Conclusion: </strong>It was concluded that among the three types of cleft (CL, CP and CLP), CLP is the most common type. The males are affected more with cleft lip and/or palate than the females. Clefts also have risks of associated congenital anomalies. Exposure to teratogenic agents in first trimester of pregnancy is also associated with orofacial cleft.</p> Sanzida Khatun, Dr ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 https://www.nepjol.info/index.php/OJN/article/view/25682 Fri, 20 Sep 2019 00:00:00 +0000 Comparison of Shear Bond Strength of Two Commercially Available Bondable Molar Tubes https://www.nepjol.info/index.php/OJN/article/view/25683 <p>&nbsp;<strong>Introduction: </strong>Direct and indirect bonding has revolutionized clinical orthodontics by reducing chair-side time and enhancing patient comfort. Clinicians often hesitate to bond molars due to ambiguity on shear bond strength. This study was conducted to compare shear bond strengths of two commercially available bondable molar tubes. And asses mesh if the mesh design had a role to play in differences in shear bond strength.</p> <p><strong>Materials &amp; Method: </strong>30 extracted maxillary molars were divided into Group I and II (n=15).Group I bonded with Victory series MBT (3M Unitek). And Group II bonded with Ortho classic proprietary Pad- Lok (Navy orthodontics). Teeth were mounted on a jig and Shear Bond Strength was evaluated on an Instron universal testing machine at a cross head speed of 1mm/minute. They were also subjected to scanning microscopic examination to check the base pattern.</p> <p><strong>Result: </strong>Shear bond strength of navy orthodontic tubes were (18.0675+/- 4.0187 MPa) was significantly higher than 3M victory series (8.93 +/2.493MPa). Unpaired T-test shows a higher significant difference in SBS between two groups at 1% of significance. SME showed that navy orthodontic tube base was pad-lock mesh design, while 3M was a single mesh base design.</p> <p><strong>Conclusion: </strong>3M victory series molar tube exhibited a near ideal while other sample showed far higher shear bond strength than recommended. Higher values may result in enamel fracture.</p> Vivek Bikram Thapa, Dr, Amrita Shrestha, Dr, Prabesh Sherchan, Dr, Prakash Poudel, Dr, Luna Joshi, Dr ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 https://www.nepjol.info/index.php/OJN/article/view/25683 Fri, 20 Sep 2019 00:00:00 +0000 Relationship between skeletal malocclusion and dental anomalies in Nepalese population https://www.nepjol.info/index.php/OJN/article/view/25684 <p><strong>Introduction: </strong>Teeth eruption is important for the development of alveolar process which increases vertical height of the face and third molar is the last tooth to erupt in the oral cavity after birth. The aim of this study was to determine relationship between skeletal malocclusion and dental anomalies in Nepalese population.</p> <p><strong>Materials &amp; Method: </strong>A sample of 170 patients with agenesis of at least one third molar was divided into four groups according to the third-molar agenesis pattern. Panoramic radiographs, lateral cephalograph and cast models were used to determine the skeletal malocclusion and associated dental anomalies. The Pearson chi-square test was used for stastical analysis.</p> <p><strong>Result: </strong>Among 170 patients more than half of the patients were female with the average age being 18.15 ± 3.64 years. Majority of the patients had Class I skeletal malocclusion followed by Class II and III but on group wise comparison of patients with different skeletal patterns Class I skeletal malocclusion had highest prevalence of dental anomalies followed by Class III and Class II malocclusion.</p> <p><strong>Conclusion: </strong>Prevalence of third-molar agenesis was more in skeletal class I malocclusion followed by class II and III but skeletal Class I malocclusions had more dental anomalies followed by class III and class II malocclusion.</p> Bashu Dev Pant, Dr, Anjana Rajbhandari, Dr, Resina Pradhan, Dr, Manju Bajracharya, Dr ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 https://www.nepjol.info/index.php/OJN/article/view/25684 Fri, 20 Sep 2019 00:00:00 +0000 Changes in vertical dimension: Extraction versus non-extraction https://www.nepjol.info/index.php/OJN/article/view/25685 <p><strong>Introduction: </strong>To evaluate and compare the vertical changes in patients treated orthodontically with or without different patterns of premolars extraction.</p> <p><strong>Materials &amp; Method: </strong>The lateral cephalograms of 112 orthodontically treated patients were categorized into four groups of 28 each based upon extraction strategy.

The virtual model of the predicted tooth position was superimposed on the virtual model of the achieved tooth position at various stages over their stationary posterior teeth by using MeshLab software. The amount of tooth movement predicted was compared with the amount of tooth movement achieved.</p> <p><strong>Result: </strong>The results of this study have shown that when a comparison was made on the basis of irregularity scores in both the groups, it was seen that the irregularity score was more in Clinical STL group at each stage such as 2.55 at T4, 1.65 at T6 and 1.0 at T8 whereas 2.0 at T4. 0.90 at T6 and 0.25 at T8 in the Software model group. Also, On comparing mean accuracy these three stages, the analysis of data showed the mean accuracy at T4 is 62.5%, mean accuracy at T6 is 68.8% and the mean accuracy at T8 is 78.1%.</p> <p><strong>Conclusion: </strong>The predicted software models do not accurately reflect the patient’s tooth position .There is an overestimation by predicted software as compared to actual clinically achieved tooth position. There is a need of overcorrection to be built in the treatment planning stage itself and execution of the anticipated end result.</p> Arisha Izhar, Dr, Gurkeerat Singh, Dr, Varun Goyal, Dr, Rajkumar Singh, Dr, Nishant Gupta, Dr, Prerna Pahuja, Dr ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 https://www.nepjol.info/index.php/OJN/article/view/25686 Fri, 20 Sep 2019 00:00:00 +0000 Comparison of ANB Angle, Yen Angle and W Angle in Chinese Population https://www.nepjol.info/index.php/OJN/article/view/25688 <p><strong>Introduction: </strong>An accurate, reliable and stable method of accessing sagittal jaw relationship with cephalometric analysis is essential in orthodontic diagnosis and treatment planning. Many methods have been developed to assess antero-posterior jaw discrepancy but they all have some shortcomings including ANB angle. Thus the purpose of this study is 1) To provide mean values and standard deviations for ANB angle, Yen angle and W angle for a sample of skeletal Class I, II and III Chinese males and females malocclusion patients; 2) To verify the existence of sexual dimorphism; 3) To compare these three methods for assessing sagittal jaw relationship 4) To assess the correlation between these and 5) To find out which is the most reliable amongst them.</p> <p><strong>Materials &amp; Method: </strong>120 pretreatment lateral cephalograms of Chinese patients, including both males and females between 18 to 25years old, were collected from the Department of Orthodontics; Wuhan Union Hospital which were divided into 3 groups as Class I, II and III skeletal pattern. Each pattern consists of 40 samples. The values of the males and females were compared with independent t-test while the inter-group comparisons were conducted with ANOVA and Tukey’s test. Pearson correlation test was performed to correlate between these angles.</p> <p><strong>Result: </strong>There were no statistically significant differences between the mean values of these angles in male and female within the groups in all three classes. ANOVA analysis showed significant differences were found in ANB angle, Yen angle and W-angle in all the three Groups. Strong correlation existed between Yen angle and W angle.</p> <p><strong>Conclusion: </strong>There is no existence of sexual dimorphism in our study. ANB angle is affected by growth of Nasion while Yen angle is affected by rotation of jaws. ANB angle is easy to assess while W angle is most stable and reliable.</p> Surendra Maharjan, Dr, Chen Lili, Dr ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 https://www.nepjol.info/index.php/OJN/article/view/25688 Fri, 20 Sep 2019 00:00:00 +0000 Orthodontic Treatment Knowledge among General Dentists and Non-orthodontic Specialists https://www.nepjol.info/index.php/OJN/article/view/25689 <p><strong>Introduction: </strong>General dentists and specialists other than orthodontist may encounter patient requiring orthodontic treatment. For proper counseling and referral, it is important that general dentists and non-orthodontic specialists have adequate level of orthodontic knowledge.</p> <p><strong>Objective: </strong>To assess the knowledge of orthodontic treatment among general dentists and non-orthodontic specialists and to compare the knowledge between the two groups.</p> <p><strong>Materials &amp; Method: </strong>A descriptive cross sectional study using questionnaire was performed among 185 actively practicing general dentists and non-orthodontic specialists of Nepal. The questionnaire comprised of three parts. The first part included demographic details, second part contained 5 multiple choice questions regarding orthodontic counseling and third part integrated 18 questions for evaluating knowledge of orthodontic treatment. Each correct answer was given score 1 and every incorrect answer was scored zero in the third part of the questionnaire.</p> <p><strong>Result: </strong>Among total participants, 60.5% think first orthodontic evaluation of a child should be carried out within 7 to 8 years of age and 44.3% think orthodontic treatment can even be started after 40 years of age. Around 66% of the participants think that orthodontic treatment cannot be performed in periodontally compromised cases. No significant difference was found between the mean scores of knowledge among general dentists and non-orthodontic specialists (<em>p</em>=0.891), or among dentists with different years of experience (<em>p</em>=0.644).</p> <p><strong>Conclusion: </strong>There is a need for more education of orthodontic treatment concepts to the dentists who do not belong to orthodontic field for proper counseling and referral.</p> Asal Acharya, Dr, Praveen Mishra, Dr, Rabindra Man Shrestha, Dr, Pooja Shah, Dr ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 https://www.nepjol.info/index.php/OJN/article/view/25689 Fri, 20 Sep 2019 00:00:00 +0000 Prevalence of Lip Competency among Nepalese Adolescents with different Ethnic group of Kathmandu Valley https://www.nepjol.info/index.php/OJN/article/view/25690 <p><strong>Introduction: </strong>Esthetic is one of the outcome that is expected from orthodontic treatment. In orthodontic practice, lip protrusion has been observed with proclined upper and lower incisors in bimaxillary protrusion. Such lip protrusion has been shown to be reduced with backward movement of the anterior teeth, which often accompanies premolar extraction. Hence the aim of our study is to find out prevalence of lip competency among Nepalese Adolescents with different ethnic group of Kathmandu valley.</p> <p><strong>Materials &amp; Method: </strong>lt is a cross-sectional descriptive study. The study population included 14-18 year-old adolescents studying in high school of all three districts of Kathmandu Valley. An evaluation form was developed categorizing different levels of deep bite following WHO guidelines 1985 and accordingly data were recorded on it.</p> <p><strong>Statistical Analysis: </strong>Data were analyzed with descriptive statistics using the Statistical Package for the Social Sciences (SPSS for Windows, Version 23) in which p-values were calculated by Pearson Chi-Square Tests.</p> <p><strong>Result: </strong>Out of 935 screened students, 89.6% had competent lips and 10.4% had Incompetent lips. Female showed 91.9% of competent lips and 8.1% of incompetent lips. Male showed 87.8% of competent lips and 12.2% of incompetent lips. Among different ethnic group for lip competency, Advasi/Tharu showed 0.2%, Brahmin/chettri showed 61.6%, Dalit showed 0.6, janajati- Hi showed 35.8%, Madhesi showed 0.7%,Muslim showed 0.6% and others showed 0.3%. Among Brahmin/chettri 56.4% showed competent lips, 5.22% showed incompetent lips.

Thus, orthodontist has control over lip prominence to enhance beauty by altering skeletal and dental relation. Hence analyzing lip prominence is essential for the success of orthodontic treatment. The aim of the present study is to determine lip prominence using different reference planes and secondly to assess sexual differences in lip prominence.</p> <p><strong>Materials &amp; Method: </strong>lateral cephalograms of 43 (23 males and 20 females) Brahmins aged 18 - 27 years were collected. They were having dentally: Angle’s Class I molar and canine relation with normal overjet and overbite and skeletally: normal jaw relationship, symmetric face with acceptable facial profile, without craniofacial abnormalities. Linear distance was measured in lateral cephalograms from most prominent point of the lip to reference planes of different analysis system. Comparative test was conducted within Brahmins to check gender diversity at significance level p ≤ 0.05.</p> <p><strong>Result: </strong>Comparison of lip prominence of male and female Brahmins were found to have no statistically significant differences except for the upper lip to Burstone B line (p ≤ 0.05) and lower lip to Holdaway H line (p ≤ 0.05). When means of males and females were compared males were found to have more protrusive lips.</p> <p>The Result of this study indicates protrusive lips of Brahmins compared to the established norms of Caucasians as analyzed with reference plane of different analysis system namely Ricketts, Steiners and Burstones. Sushners analysis showed retrusive lips indicating retrusive lips of Brahmins as compared with Black population.</p> <p><strong>Conclusion: </strong>During orthodontic treatment planning lip prominence should be emphasized based on gender and ethnicity.</p> Resina Pradhan, Dr, Anjana Rajbhandari, Dr, Manju Bajracharya, Dr, Pushkar Manandhar, Dr, Surendra Maharjan, Dr ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 https://www.nepjol.info/index.php/OJN/article/view/25691 Fri, 20 Sep 2019 00:00:00 +0000 Cephalometric Approach to Vertical Facial Height https://www.nepjol.info/index.php/OJN/article/view/25692 <p><strong>Introduction: </strong>The vertical heights and the proportions are very important for balance of the face and attractiveness along with the good smile. Harmonious vertical proportions and the Antero-posterior relations contribute to aesthetics.

The most common etiology include tooth size and arch length discrepancy. Maxillary lateral incisors vary in form more than any other tooth in the mouth except the third molars. Microdontia is a condition where the teeth are smaller than the normal size. Microdontia of maxillary lateral incisor is called as “peg lateral”, that exhibit converging mesial and distal surfaces of crown forming a cone like shape. A carefully documented diagnosis and treatment plan are essential if the clinician is to apply the most effective approach to address the patient’s needs. A patient sometimes requires a multidisciplinary approach to correct the esthetics and to improve the occlusion. This case report describes the management of an adult female patient with a proclined upper anterior teeth, upper anterior spacing, deep bite and peg shaped upper right lateral incisor tooth through orthodontic and restorative treatment approach.</p> Sanjay Prasad Gupta, Dr ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 https://www.nepjol.info/index.php/OJN/article/view/25695 Fri, 20 Sep 2019 00:00:00 +0000 Dentoalveolar Distalisation in Class III Skeletal Base Using Buccal Shelf Mini-implants - A Case Report https://www.nepjol.info/index.php/OJN/article/view/25696 <p>Before the advent of skeletal anchorage distalisation of the lower arch was considered cumbersome. Individual lower molar distalisation followed by retraction into the distalised space created is very time-consuming. Therefore, to reduce the treatment duration lower arch distalisation can be attempted by using buccal shelf screws. Here we present a case of Angle’s Class III malocclusion which has been treated effectively with distalisation of lower arch using 2 buccal shelf screws (2x12mm) with elastic chains following lower third molars extraction. We achieved full arch distalisation of 3.5mm bilaterally in a span of 1.5 months into a class I molar and canine relationship with normal overjet and overbite. Total treatment duration was of 17 months. These results were stable. There were no changes in vertical facial dimensions.</p> Narula Khyati, Dr, Shetty Siddarth, Dr ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 https://www.nepjol.info/index.php/OJN/article/view/25696 Fri, 20 Sep 2019 00:00:00 +0000
