ABSTRACT Objectives To examine the effect of micro-osteoperforation (MOP) on the space closure rate using passive self-ligating or conventional brackets. Materials and Methods This was a two-arm parallel randomized controlled trial undertaken at the outpatient department of a dental college. There were 60 participants (30 women and 30 men) who fulfilled the inclusion criteria. Both the study and control groups were subjected to MOPs throughout the period of space closure. MOPs were repeated every 28 days. The experimental group (mean age 19.5 ± 1.66 years) was bonded with passive self-ligating brackets while the control group (mean age 19.9 ± 1.13 years) was bonded with conventional brackets. Both groups were examined and compared for rate of space closure. An evaluation was conducted for both groups until the entire extraction space was closed and confirmed by evaluation of a tight contact between the canine and the second premolar using a piece of dental floss. Results Before the initiation of retraction, all initial criteria were similar between the two groups (P > .05). No difference was observed between the two groups in the rate of space closure (P > .05). Conclusions MOP in conjunction with passive self-ligation does not increase the rate of orthodontic space closure when compared with MOP used with conventional brackets.

Introduction: Due to the fundamental role of esthetics in the outcomes of dental treatments, especially in the anterior region (esthetic zone), the necessity of considering the matter of esthetics in clinical studies has become into focus in the current era. The aim of this study was the evaluation of esthetic outcomes of two treatment protocols in the treatment of congenital uni-lateral missing of maxillary lateral incisors as well as patient satisfaction from the treatment outcomes. Methods: in this study the sample size was 24 people (16 women and 8 men), These individuals sought dental treatment for replacement of the congenitally missing maxillary lateral incisor. Convenience sampling method was used and patients were divided into two groups regarding the kind of treatment they received. The two treatment protocols included: 1. Space closure by means of orthodontic treatment and then reshaping the canines; and 2. Space regaining by means of orthodontic treatment and replacing the lateral incisor with dental implants. Photographs of patients were acquired from the frontal view with retraction of the lips using digital cameras. Photographs were evaluated for Pink esthetic score. Results: No significant difference was detected between the two study groups in the evaluated factors in this study. Conclusion: The results of this study indicated that there is no significant difference in esthetic results in the two groups. Furthermore, both groups lead to similar results in patient satisfaction from treatment outcomes.

Objective: To evaluate and compare the leptin levels in gingival crevicular fluid (GCF) and rate of canine retraction using an elastomeric chain and nickel–titanium (NiTi) closed coil spring. Design: In vivo, clinical study. Setting: Orthodontic department at ITS Centre for Dental Studies and Research, Ghaziabad, India. Participants: Twenty-seven patients reported to the Department of Orthodontics at ITS Centre for Dental Studies and Research. Methods: Twenty-seven patients were included in the study in which canine retraction was carried out with an elastomeric chain and NiTi closed coil spring on either side of the arch applying 150 g of force on both sides. GCF samples were collected before the commencement of canine retraction, on the first, seventh and 21st day after application of force and were analysed for leptin levels by the ELISA technique. Impressions for the study model were taken at baseline and after 21 days to measure the rate of tooth movement bilaterally with an electronic digital calliper. Results: The results obtained within both groups showed a significant decrease in leptin levels from baseline to 21 days ( P = 0.0001). There was no significant difference in leptin levels between both groups, but leptin levels decreased more in the NiTi closed coil spring group. The rate of tooth movement is not significantly different between both groups, but space closure is faster in the NiTi closed coil spring group. Conclusions: Leptin levels in GCF showed a significant decrease during canine retraction using an elastomeric chain and NiTi coil spring; there was no significant difference in the rate of tooth movement between both the groups.

Lateral Incisor Agenesis

Maxillary lateral incisor agenesis is the most prevalent developmental dental anomaly. The management of missing lateral incisor was either closure using canine as substitution or creation of space orthodontically for prosthetic replacement. A careful diagnosis and treatment plan are deemed essential to address the patient’s needs as the spacing is present in the esthetic region. Such problem is very challenging for orthodontists, prosthodontists, and general practitioners. This case report describes the orthodontic management of a 22-year-old adult female patient with missing upper left lateral incisor tooth and upper anterior spacing by closing the space with canine lateralization and reshaping to simulate it with the lateral incisor. However, some modifications in the treatment mechanics are crucial to achieve the optimal esthetic and to improve the occlusion. Space closure with canine lateralization option seems less invasive, treatment can be completed relatively in a short period of time, and its adaptation with the facial changes throughout life without having artificial prosthesis provided other factors favoring for this option.
