Abstract: Patients undergoing fixed orthodontic treatment are usually recalled electively for the adjustments of the appliances, but sometimes they appear suddenly for emergency visit which must be addressed immediately. The primary objective of this study was to assess the nature and frequency of emergency visits made by patients under labial fixed orthodontic therapy. The secondary objective was to compare these visits between genders and age groups. The study was conducted at orthodontic clinic, B. P. Koirala Institute of Health Sciences, Dharan, Nepal. All the patients undergoing fixed labial orthodontic treatment were included and followed up for a period of 6 months. The reason for emergency appointment was recorded along with the demographic and clinical details. Chi-square test was used to find out the possible association between gender and age group with emergency appointment. Of 327 patients undergoing active fixed orthodontic therapy, 199 were female and 128 were male. A total of 176 emergency appointments were encountered during the study period of 6 months. The most common reason was the loosening of brackets or bondable buccal tubes (118) followed by loosening of bands (45). Other reasons were trauma to the buccal mucosa by the overextended wire (5), detachment of buccal tubes from the band (5), tearing of bands (3), breakage of acrylic plate (2), loosening of ligature tie (1), and dislodgement of elastomeric chain (1). Emergency appointments were not found to have statistically significant association with age group (χ 2 = 0.073, P = 0.787) or the gender (χ 2 = 3.196, P = 0.074). Loosening of the brackets or bondable buccal tubes was the most common cause for emergency visit. No significant association was found between the gender and age group with such visits.

Abstract: Introduction. For proper management of anxious dental patients it is imperative to assess their levels of dental anxiety before treatment. Modified Dental Anxiety Scale (MDAS) is the most commonly used questionnaire to assess dental anxiety. But a Nepali version of MDAS is still lacking. Hence, the objective of this study was to develop a reliable and valid Nepali version of MDAS. Materials and Methods. The English version of the MDAS was translated into Nepali following a forward and backward translation process. Following pretesting and cognitive interviewing a final version of Nepali questionnaire was obtained. One hundred and fifty patients attending Department of Orthodontics completed the Nepali version of MDAS questionnaire at their convenience. Also, patients were asked to rate their overall anxiety on a 100 mm visual analog scale (VAS). A test-retest of the questionnaire was performed with 30 patients after 2 weeks. Results. Cronbach’s alpha value of the Nepali version of MDAS was 0.775. The Intraclass Correlation Coefficient between test and retest was 0.872. Spearman’s correlation coefficient between the total MDAS score and VAS score was 0.838. Conclusion. The translated Nepali version of MDAS is a reliable and valid instrument to measure the dental anxiety of Nepali patients.

Abstract: Impaction of teeth affects patients’ esthetics, speech, and masticatory efficiency. In addition, the transposition of teeth makes a case difficult to manage. This case report describes a case of a 14-year-old boy with the impaction of the maxillary right central incisor and canine along with the transposition of the right canine and lateral incisor. The impacted teeth were surgically exposed and guided into the arch using orthodontic traction. Likewise, the transposition was corrected orthodontically by moving the teeth to their desired position without any detrimental effect on the adjacent teeth. The patient’s esthetics and occlusion improved substantially after the orthodontic intervention.

Abstract: Objective . This study aimed to find out the change in esthetic ratios during rotation of patient’s head using a simulation. Materials and Methods. A plaster study model was photographed placing its midline along the long axis of the camera. Then a series of photographs were taken by rotating the model each degree till 10° on both right and left sides. These photographs were digitally measured and the ratio of the maxillary anterior teeth at zero-degree rotation was compared with that at various degrees of rotation. Results . As the model was rotated to the right side till 10°, the ratio of the right lateral to central incisor gradually decreased while the ratio of the left lateral to central incisor gradually increased. However, the ratio of the canine to lateral incisor on both sides gradually increased. Similar results were obtained when the model was rotated to the left side. The ratio of the lateral to central incisor deviated from the acceptable range (±10%) when there was rotation of more than 7°, whereas the ratio of the canine to lateral incisor was within the acceptable range till 10° rotation on either side. Conclusions . Rotation of the model by more than 7° leads to a substantial change in the esthetic ratio.

Abstract: Background. With the changing paradigm from primarily hard tissue to soft tissue evaluation for orthodontic diagnosis and treatment planning, the priority has shifted to bring about improvement in the profile and smile characteristics of patients. Since not only the esthetics but also the stability of orthodontic treatment is largely determined by the soft tissue envelope, proper positioning of the soft tissue drape becomes paramount. Soft tissues of face, namely, nose, lips, and chin, are of paramount importance not only from an esthetic but also from functional and treatment stability points. Objective. To determine the morphological variation of lips, nose, and chin in different skeletal malocclusions. Materials and Methods. Lateral cephalograms of 237 patients visiting the department of orthodontics, BPKIHS, were taken, hand traced on matt acetate tracing paper of 0.002″ thickness with 0.3-mm 2B pencil. S les were ided into 3 skeletal classes based on ANB angle. Measurements were made in relation to the nose, lips, and chin. Data were inserted in to SPSS and analyzed statistically using descriptive statistics, and mean and standard deviation was calculated for each variable. Multiple comparison between groups was done with post hoc Bonferroni test with mean difference significant at p 0.05 . Result. On intergroup comparison, a significant difference was found for upper lip thickness (ULT) between Class II and Class III, and lower lip length (LLL) between Class I and Class III, and between Class II and Class III. Significant difference for nasolabial angle (NLA) was found between Class II and Class III. Similarly, a significant difference for the vertical chin parameter (CTV) was found between Class I and Class III, and between Class II and Class III. Conclusion. Both upper and lower lip thicknesses were highest for Class III followed by Class I and Class II, respectively. Lip lengths too were found to be highest for Class III skeletal relation. Nasolabial angle was larger in Class II malocclusion when compared to Class I and Class III. Similarly, both nasal length and nasal height measurements were in the order of Class III Class II Class I. Both horizontal and vertical chin parameters were larger for Class III sagittal relation.

Abstract: Background: Orthodontics has recently seen an increase in the number of adult population seeking treatment. Financial dependency, increasing awareness and availability of service can be the reasons behind this rise. Though, clinical myths regarding duration, effectiveness of treatment, associated systemic conditions still exist, these should be of no concern and with adequate monitoring and procedural modifications, conventional orthodontic treatment is possible.Case description: A 58 year old Type II diabetic male presented to orthodontic clinic with unesthetic gap between upper front teeth. The history revealed extraction of painful mesiodens. On examination, the patient had Class I molar, canine and incisor relationship. 21 was rotated with 5mm of space between central incisors. Fixed orthodontic treatment was planned after physician consultation regarding his diabetic condition. Bondable buccal tubes instead of bands were used in first molars, 0.022” Roth brackets were bonded on other maxillary teeth. The wire gradually progressed from 0.014”NiTi, 0.016”NiTi to 0.018”SS. Lingual button was attached on the labial and lingual surface of 21 to apply couple. After the correction of rotation of 21, remaining space closure with esthetic contouring of 21 was done. Maintenance of adequate oral hygiene was reinforced throughout the treatment period. Fixed lingual retainer was bonded and pericision performed to retain the achieved result.Conclusion: Orthodontic treatment can be carried out in diabetic adults with good glycemic control to achieve esthetic results however, measures for maintenance of adequate oral hygiene should be undertaken. Interdisciplinary approach involving restorative procedures can enhance the esthetics achieved.JCMS Nepal. 2015 (3):30-34

Abstract: Introduction: The angle between Frankfort horizontal (FH) plane and Sella-Nasion (SN) plane is considered to be 7°. Various studies have shown that the FH-SN angulations could vary which can affect cephalometric diagnosis.Objective: To determine average FH-SN angle for a group of Nepalese orthodontic patients. The secondary objectives were to assess whether the FH-SN angle exhibits sexual dimorphism and to evaluate the FH-SN angle in different skeletal relationships.Materials & Method: Lateral cephalograms of 238 orthodontic patients were hand traced and the angle between the FH and SN plane was measured and recorded. The cephalograms were also classified as skeletal Class I, II or III cases using Wits appraisal.Result: The average FH-SN angle was 6.71° ± 3.13°. FH-SN angle was greater in female s les compared to males. However, the difference was not statistically significant. Similarly, the ANOVA analysis revealed no significant difference between FH-SN angles in different skeletal relationships.Conclusion: The average FH-SN angle for a group of Nepalese orthodontic patients was 6.71° ± 3.13°. There was no statistically significant difference in FH-SN angle between skeletal Class I, II and III relationships

Abstract: Introduction: Investigators have drawn nasolabial angle using different soft tissue landmarks. This has created confusion among the orthodontic students and clinicians regarding its construction.Objective: To evaluate two commonly used methods of constructing the nasolabial angle in order to establish a single reproducible method. Materials & Method: Lateral cephalograms of 120 patients undergoing orthodontic treatment were obtained from the records of the patients. Soft tissue profile on the lateral cephalograms were traced manually by the principal investigator. All the tracings were photocopied and 6 copies of each tracing were made. Nasolabial angles were constructed and measured on photocopied copies of the tracings first using the anatomic point method and then using the tangent line method by the principal investigator and another investigator independently. Result: The average nasolabial angle values for anatomic point method and tangent line method were found to be 94.32° ± 14.05° and 92.4° ± 14.59° respectively. The intra-class correlation coefficient demonstrated excellent intra-observer and interobserver agreement among the two methods of nasolabial angle construction.Conclusion: Both anatomic point method and tangent line method of nasolabial angle construction have excellent reproducibility in terms of intra-observer and inter-observer agreement.
