OBJECTIVES:To evaluate and compare the effect of different enamel deproteinizing agents on topographic features of enamel and shear bond strength before acid etching.MATERIALS AND METHOD:In total, 120 sound human maxillary premolars were taken and divided into three groups: Group 1 control (37% phosphoric acid (H3PO4), Group 2, (5.25% Sodium Hypochlorite (NaOCl)+ 37% H3PO4, and Group 3, (10% Papain gel + 37% H3PO4). These groups were further divided into A and B subgroups. In subgroups 1A, 2A, and 3A (n30) topographic features were evaluated using Scanning electron microscope (SEM) at different magnifications. Insub-groups 1B, 2B, and 3B (n90) metal brackets were bonded with Transbond™ XT, and all the samples were subjected for Shear Bond Strength (SBS) evaluation using universal testing machineat a cross speed of 0.5 mm2/min. The failure mode was analyzed using adhesive remnant index (ARI). Statistical analysis was done using one-way ANOVA for the shear bond strength, and Kruskal-Wallis test followed by Mann-Whitneywas performed for ARI scores.RESULTS:SEM showed predominance of type 3 etching pattern in control Group (1A) and type 1 and type 2 in deproteinizedGroups (2A and 3A). Mean values of shear bond strength showed statistically significant differences between evaluated groups (P < 0.005). The lowest and highest shear bond strength was attributed to Group 1B (Control) and 3B (10% papain gel), respectively. Statisticallysignificant differences were noted for the mean ARI scores between control and deproteinized group (P < 0.05).CONCLUSION:10% papain geland 5.25% NaOCl can be used as deproteinizing agents on enamel surface before acid etchingto enhance the shear bond strength of orthodontic brackets.

Anterior dental crossbite is a common problem in which maxillary anterior teeth are locked behind the mandibular anteriors. Orthodontic treatment of anterior teeth crossbite need unlocking of upper anterior teeth. Several methods are used to raise the bite for anterior teeth crossbite correction. Posterior acrylic bite blocks are commonly used to raise the bite. Here, in this article, a new method is described to retain the posterior bite block for anterior crossbite correction.

Aims and objectives:The study was undertaken to estimate the availability of literature on PubMed-Medline by Indian orthodontists from 1990 to 2011 by using bibliometric analysis. Materials and methods:Articles available on PubMed-Medline database in time span of 1st January 1990 to 31st December 2011, where authors' affiliation had the words 'Dental' and 'India' were selected. The information collected were: Name of the journal, year of publication, specialty of first author, number of authors, reach of the journal, status of the journal, , state of origin, and type of article. From this data, the performance of specialty of orthodontic was analyzed.Results: Out of total of 242 articles, 189 got published in international journals and 53 in Indian journals. 50 (20.6%) were published in Journal of Clinical Orthodontics followed by 37(15.2%) in American Journal of Orthodontics and Dentofacial Orthopedics. 102 (42.1%) were original research done by authors. 91(37.6%) articles were from institutes in Karnataka, followed by Tamil Nadu (12.8%), Delhi (11.1%) and Maharashtra(9.5%). There seems to be boom in the publication trend since 2006. Conclusion:The results of this study could be used by various professional societies, individual scientists, scholarly institutions and funding organizations to frame essential policies regarding the improvement of the science of orthodontists and to the benefit of common Indians.
