SUMMARY A 12-year-old boy with extrusion of the maxillary right central incisor, uncomplicated fracture of the left central incisor, avulsion of the mandibular right and left central incisors, and crown fracture of the mandibular right lateral incisor presented to the Kocaeli University Department of Pediatric Dentistry 20 days after sustaining the traumatic injuries. Orthodontic repositioning of the extrusive maxillary right central incisor was planned. Additionally, this tooth was necrotic and needed root canal treatment. The maxillary left central incisor and right mandibular lateral incisor were necrotic and needed root canal treatment. The orthodontic and endodontic treatments were successfully performed simultaneously. Restoration of the fractured mandibular right lateral incisor and maxillary left central incisor was completed with resin composite. Subsequent to orthodontic and endodontic treatment, prosthodontic rehabilitation was performed. At the two-year followup, the teeth appeared normal and the patient had no complaints.

Abstract Objective: To compare the forces resulting from four types of bracket/ligature combinations: ceramic brackets and stainless steel brackets combined with unconventional elastomeric ligatures (UEL) and conventional elastomeric ligatures (CEL) during the leveling and aligning phases of orthodontic therapy. Materials and Methods: The testing model consisted of five 0.022-inch preadjusted brackets (second premolar, first premolar, canine, lateral incisor, and central incisor) for each of the two bracket types. The canine bracket was welded to a sliding bar that allowed for different amounts of offset in the gingival direction. The forces generated by a 0.014-inch superelastic nickel titanium wire in the presence of either the UEL or CEL bracket/ligature systems at different amounts of upward canine misalignment (1.5 mm, 3 mm, 4.5 mm, and 6 mm) were recorded. Results: Significant differences were found between UEL and CEL systems for all tested variables (P &lt; .01) with the exception of the canine misalignment of 1.5 mm. The average amount of recorded force in the presence of CEL was negligible with 3.0 mm or greater of canine misalignment. On the contrary, during alignment, a force available for tooth movement was recorded in the presence of both ceramic and stainless steel brackets when associated with UEL. Conclusions: The type of ligature used influenced the actual amount of force released by the orthodontic system significantly more than the type of bracket used (stainless steel vs ceramic).

Objective To investigate the existence and suitability of mathematical proportions between the widths of maxillary anterior teeth in Bangladeshi population having an esthetic smile, with the aid of digital photographs and computer analysis. Place of Study The study was conducted at the Department of Orthodontics and Dentofacial Orthopedics of Dhaka Dental College and Hospital, Dhaka. Period of Study The study was conducted from April 2016 to September 2016. Sample Selection The study samples collected from Students of Dhaka Dental College, Mirpur-14, Dhaka, Bangladesh, with age limit 18–35 years. Materials and Methods Standardized frontal images of 100 dental students of Dhaka Dental College were captured. All the images were downloaded to a personal computer, and width of each tooth was measured by the scale tool of Photoshop CS version 8.0. All the data were analyzed (through standard statistical method) using Statistical Package for Social Science Software version 20 (IBM Corp., USA). Results The golden proportion existed in 17% of the perceived width ratios of lateral incisor to central incisor and 4% of the width ratios of canine to lateral incisor in natural dentition. Sixty-six percent lateral incisors are following the golden percentage, but only 7% central incisors and 21% canines are following the golden percentage. The recurring esthetic dental (RED) proportion existed in only 4% of participants. Conclusions The golden proportion, golden percentage, and the RED proportion cannot be used as constant proportions to create a harmonious proportion throughout the width of maxillary anterior teeth. The adjusted golden percentage might serve as a guideline to create harmonious proportions in maxillary anterior teeth for Bangladeshi population.

Tooth transposition is a rare developmental disorder in which a normal tooth erupts in an inappropriate position. The change in position occurs between two adjacent teeth within the same quadrant. In this article, two cases of tooth transposition involving mandibular molars are described. Patient 1 presented with bilateral transposition between first and second mandibular molars. In addition, giroversion of the first molars was observed. Patient 2 presented with unilateral transposition between the mandibular left molars. Because this tooth disorder does not affect quality of life, both patients declined to seek dental treatment. Out of the 120 cases of tooth transposition found in the literature, 92,5% occurred in the maxilla and 15% were bilateral, 65,8% percent of these cases involved the canine and first premolar; 26.6% involved the canine and lateral incisor; 2,5% involved the canine and central incisor; and only 0.85% involved the first and second molar. The majority of tooth transposition cases occurred in women (66,6%). In literature, tooth transposition is a poorly-documented condition. Consequently, this report seeks to contribute to the existing information in the literature on this disorder.

ABSTRACT Concurrent impaction and transposition of maxillary anterior teeth is uncommon and poses a challenge for dentists. Early diagnosis and management of eruption disturbances benefits esthetic and functional outcomes. This article describes the treatment of a teenager who had impactions of the left maxillary central incisor and canine as well as ipsilateral canine-lateral incisor transposition. Treatment alternatives and effective orthodontic techniques are delineated. To optimize the treatment results, the impacted maxillary canine was surgically exposed and orthodontically distalized with an innovative cantilever. Subsequently, the deeply impacted maxillary central incisor was uncovered and orthodontically mesialized into the arch. Finally, the displaced maxillary lateral incisor was brought into its normal position. The combined surgical-orthodontic approach resolved a difficult clinical issue and avoided additional restorations. An esthetic, functional outcome was achieved and satisfied the patient.

Abstract Objective: The objective of our work is to examine the presence of the much-discussed golden proportion provided by Levin, and of the golden percentage (Snow), on the widths of maxillary anterior teeth, by measurements made on digital images. Material and method: The material of this study consists of digital photographs taken of subjects with natural and esthetic teeth. We took photos of 68 subjects (35 women and 33 men), between 19 and 26 years. Using a computer program, we made the necesarry measurements, then we made the appropriate calculations of the above theories. Results: The golden proportion between the lateral and central incisor occurs in a higher proportion than between the canine and the lateral incisor. The values obtained by analyzing the golden proportion differ slightly from those proposed by Snow. Conclusions: The frequency of the golden proportion is not significant for the groups of teeth mentioned. With small modifications and taking into consideration ethnic differences, Snow's golden percentage is more valid and applicable than Levin's golden proportion is.

ABSTRACT Objective: The aim of the study was to analyze the distribution of color parameters, lightness (L*), chroma (C), hue (H), a* and b*, in the intercanine sector in maxilla. Material and Methods: Patients' tooth color measurements were performed using an intraoral spectrophotometer VITA Easyshade® (VITA Zahnfabrik H. Rauter GmbH and Co. KG, Bad Sackingen, Germany). The measurements were made in 255 subjects in the intercanine sector in maxilla. Results: The mean values for the group of 255 subjects were as follows: L*, a*, b*, C, and H as 81.6, 0.67, 21.6, 21.7, and 92.7, respectively. For F=206.27 and P < 0.001 between L*, a*, b*, C, H, and central incisor/lateral incisor/canines, there were statistically significant differences. Conclusion: With the statistical analysis, it was determined that there are significant color differences between the teeth of the intercanine sector, which differences are clinically significant also.

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.
