Aesthetics is an integral part of orthodontics, and color is an important aspect of aesthetics. Hue, value, and chroma are the three objective variables used to describe color. The tooth color exhibits a large variation influenced by the structure of enamel and dentin. Enamel colour alterations may derive from the irreversible penetration of resin tags into the enamel structure at depths reaching 50 µm. Natural Teeth: A total of 80 extracted premolar teeth were collected and then washed thoroughly with plain water and stored in normal saline to prevent them from drying up.Eighty human premolar teeth that had been previously extracted from orthodontic patients.All the teeth selected were cleansed by using a rubber cup and pumice slurry for 20 seconds on a slow speed contra angle hand piece (10,000 rpm), rinsed thoroughly with saline for 10 seconds and air-dried with gentle jets of oil-free compressed air.In this study shows the frequency distributions of color difference ΔE at various time points in Transbond XT group. The mean difference before treatment and debonding and finishing (ΔE1) was 0.91± 0.43, mean difference before treatment and photogeing (ΔE2) was 1.49±0.85 and mean difference after debonding and finishing and photoageing (ΔE3) was 0.81±0.51. The frequency distributions of ΔE at various time points in Ormco group. The mean difference before treatment and debonding and finishing (ΔE1) was 0.72±0.24, mean difference before treatment and photogeing (ΔE2) was 1.88±0.83 and mean difference after debonding and finishing and photoageing (ΔE3) was 0.97±0.55. Ormco Enlight showed highest enamel color change of ΔE2 value 2.92 after debonding & finishing. Rely A bond showed least enamel color change of ΔE2 value 2.80. Of all the groups studied there is a significant color change in the enamel but less than the minimum threshold value of ΔE 3.7 units.

A lingual jig is a simple and accurate lingual bracket-positioning device, which transfers labial bracket prescriptions to the lingual brackets. Most commercially available lingual bracket bonding jigs either require multiple wires bending customized for each tooth in each patient or require multiple jigs for individual anterior teeth. This short communication describes ASP lingual jig that can be easily and accurately used for lingual bracket placement in every patient without any design modifications.

Treatment of a malocclusion characterized by open bite can be a difficult task for the orthodontist because such a malocclusion develops as a result of the interplay of many different etiologic factors. This article presents a case series of patients showing varying degrees of anterior open bite having a tongue thrusting habit. All patients were given a tongue crib appliance along with 0.022MBT preadjusted edgewise brackets treated with different modalities. Extraction of all 1st premolars was initiated in one case and retraction of anterior teeth was done using skeletal anchorage to improve the overjet and overbite. In other cases, non-extraction therapy was advocated with a modification of MEAW technique by incorporating reverse arch wire mechanics and correcting the anterior open bite.

Superimposition is a method where serial cephalometric radiographs or tracings are taken for the same patient at different time intervals that is before, during and after treatment and superimposed on the biologically defined plane or surface to study changes in jaw and tooth positions respectively as a result from growth, treatment or a combination of two. With the progress of the orthodontic treatment as well as growth, detailed follow-up is important to monitor the changes from the treatment mechanics applied in order to enhance the dental and jaw function and dentofacial esthetics of an individual. The article aims at presenting a comprehensive review on the various methods of superimposition for proper evaluation of changes occurring in an individual following growth and treatment.

Class II malocclusion cases are of interest to orthodontist since they constitute a significant percentage of cases they treat. However, they are one of the most challenging malocclusions to diagnose and treat.There lies a significant difference in prevalence of Class II malocclusion among various populations. Prevalence of Class II malocclusion in India varies from 1.9% in Rajasthan to 8.37% in South India.Class II malocclusions have dental or skeletal or combination entities. Success in the management of skeletal Class II cases especially in the adult cases relies on proper diagnosis and treatment planning. The treatment of severe dentofacial deformities in adult patients is a challenging task for both the orthodontist and the maxillofacial surgeon. In adults with severe discrepancy, combined orthosurgical approach is the ideal way to achieve acceptable results. This case report presents an adult male patient with severe Class II malocclusion in which mandibular advancement was carried out with BSSO. Post-treatment results showed improved facial esthetics and Class- I relationship of the skeletal jaw bases with optimal dental occlusion.

Malocclusions need to intercepted at an early developing stage to prevent severe disturbing outcomes. In all reported cases, Class II is one of the most common malocclusions that is seen which requires treatment using functional appliances as it presents with considerable difficulty in later stages. Twin block has the advantage of versatility of appliance designs and they meet a wide range of requirements for correction of various types of malocclusions for patients. The aim of this study is to include all modifications that could be incorporated in the appliance design to be customized to individual patients according to their need.

The effect of racial and ethnic variations of dental morphological traits on torque expression of preadjusted edgewise appliances has rarely been documented. This in vitro experiment was carried out with the aim to study the extent to which the anterior tooth morphology of a mixed Indian population affects torque expression of a preadjusted edgewise appliance. This study was conducted on extracted maxillary and mandibular anterior teeth of a mixed Indian population. These teeth were divided into two similar groups and were bonded with 0.018” Roth and MBT prescriptions. Full slot engagement was obtained using a 0.018” x 0.025” stainless steel wire to study how the variation in the tooth morphology affects the torque expression. Each tooth with the test wire engaged in the slot was radiographed using standardised procedures. The radiographs were photographed; images were transferred to a computer and enlarged 6 times. Printouts of the images were taken and the torque expression angle for each tooth of the two groups was measured. A wide range of torque expression was obtained reflecting the influence of tooth morphology on the expression of torque, suggestive of significant variations in the tooth morphology of the same tooth type. However, the mean torque expressions obtained in this study were comparable to the average values of torque prescribed for the two prescriptions.
