Traditional bonding materials are incapable of bonding in presence of moisture, are challenged by "Moist-field" bonding materials. Claims and counter claims are made regarding their, efficacy to use as ideal orthodontic bonding adhesives. Present study done to compare Shearbondstrength of Ethyl cyanoacrylate(Smart Bond) and self cure acrylic(Rely-a-Bond) under different conditions. Rely-a-Bond and Smart Bond, are acceptable bonding materials in dry and wet conditions respectively with regards to Shear bond strength values per se. Rely-a-Bond showed significant increase in Shear bond strength...

Teeth when subjected to bleaching bring about the desiccation of the enamel, making it to reduce in its microhardness. While subjecting the freshly bleached enamel surface to various surface treatments of Casein Phosphopeptide - Amorphous Calcium phosphate (CPP-ACP) and Casein Phosphopeptide - Amorphous Calcium phosphate fluoride (CPP-ACPF) brought about the increase in its microhardness, which is assessed in this study. The bleached samples showed reduction in microhardness of enamel and also differences was found between post bleaching and samples subjected to remineralizing agents CPP-ACP...

The permanent canines are the foundation of an esthetic smile and functional occlusion. Factors that interfere with its development and eruption had serious consequences on esthetics, function and stability of stomatognathic system. The orthodontic treatment of impacted maxillary canine remains a challenge to today's clinicians. The treatment of this clinical entity usually involves surgical exposure of the impacted tooth, followed by orthodontic traction to guide and align it into the dental arch. Bone loss, root resorption, and gingival recession around the treated teeth are some of the...

FEM is a powerful contemporary research tool that has been used to study the stress distribution of non living as well as natural and restored craniofacial structures affected by three dimensional stress fields, which are difficult to assess otherwise. The three dimensional FEM used in the present study provides the freedom to simulate orthodontic force systems applied clinically and allows analysis of the response of the craniofacial skeleton to the orthodontic loads in three dimensional space. The FE analysis has the following advantages: it is a non invasive technique; the actual amount of...

Pentraxin-3 is Tumor necrotic factor (TNF)-stimulated gene 14 (TSG-14), elevated level of PTX-3 in plasma is seen in severe infections and some diseases. PTX-3 is considered as a marker of inflammation. Active tieback and NiTi coil spring are used for space closure after extraction of premolars. Active tieback is simple, economical and reliable. Nickel titanium coil springs have been shown to produce a constant force over varying lengths and duration, with no force decay. This book compares the levels of Pentraxin 3 (PTX-3) in gingival crevicular fluid (GCF) in orthodontic patients undergoing...

Cephalometric standards of one ethnic group need not apply to other ethnic groups. This study evaluated lateral cephalometric craniofacial changes between 7-10 years & differences between genders for children of Suttur. The linear increase in SNA & SNB from 7-10 years was significant. ANB, A-NPog, A: ss-n-pg there was linear decrease from 7-10 years. Mean basal vertical measurements of PFH, PFH/AFH, Jaw relation & N: Ans there was linear increase in measurement from 7-10 years. Mean values of Jaw relation, Maxillary Inclination & Mandibular Inclination decreased from 7-10 years. Jaw angle was...

Most of the craniofacial growth studies are cross-sectional in nature and provided a large number of cephalometric standards for males and females at different ages and for various ethnic groups. Variations in craniofacial Morphology exist between different ethnic and racial groups. The cephalometric standards developed for one ethnic group need not apply to other ethnic groups - the racial groups must be dealt according to their own characteristics. Limited number of longitudinal or semi-longitudinal studies has been reported for Indian population. A Rural residential Free school at Suttur,...
