Background and Objective: The objectives of this in vitro study, is to evaluate the influence of various dentin treatment procedures prior to bleaching namely, demineralization and demineralization in conjunction with deproteinization on the dentin permeability and bleaching efficacy. Method: The study used a total of 40 sound premolars, which were sectioned longitudinally, and their color coefficients and absorption spectrum was recorded and used as control values for the later study. These dentin samples were then discolored by blood and their color coefficients and absorption spectrum were calibrated. They were then divided into two Groups with 20 samples each per group. Group A - dentin samples were demineralized prior to bleaching. Group B - dentin samples were deproteinized also in conjunction to demineralization prior to bleaching. The values of color coefficient and absorption spectrum were determined using Spectrophotometer for samples of each group respectively. Results: There were significantly higher color coefficient and absorption spectrum values in the group where dentin was treated with demineralization in conjunction with deproteinization prior to bleaching when compared to the group where dentin was treated by demineralization alone prior to bleaching. Conclusion: Demineralization in conjunction with deproteinization has proven to be a good method of increasing dentin permeability for achieving a higher bleaching efficacy.
Breastfeeding is a natural safety-net for the first few months in order to give the child a fairer start to life. The American Academy of Pediatric Dentistry recognizes the distinct nutritional advantages of human milk for infants and endorsed the position of the American Academy of Pediatrics on the promotion of breastfeeding. It therefore calls for increase in need to negotiate the roles and responsibilities of pediatric dentists to eliminate the existing gaps in preventive care and anticipatory guidance. The objective of this evidence-based review is to explore the beneficial roles of breastfeeding in orofacial growth and development and endorse the same through anticipatory guidance.How to cite this article: Agarwal M, Ghousia S, Konde S, Raj S.

A primary teeth and its permanent tooth germ are most of the time seen as an inter-dependent units, where each one of them interacts with and depends on each other. Intrusive injury is a most common type of an injury to primary dentition and requires a pediatric dentist to carefully examine not only the damaged tooth, but possible sequelae to the permanent tooth germ. Alteration in eruption and / or in development, as a consequence of inflammation / infection of the preceding primary teeth, such as: hypoplasia, morphological alteration on the dental crown or total arrest of radicular formation. The response of the dento-alveolar apparatus to infection is characterized by inflammation which may result in tooth resorption. This may be a consequence of infective endodontic pathosis alone or superimposed on trauma induced resorption. These infection induced resoprtions, which are generally termed inflammatory root resorptions, may occur as internal resorptions, external resorptions or combined internal -external lesions. This manuscript will present a rare case of a primary tooth onto its permanent tooth bud that showed one such case scenario of a pathological root resorption of primary teeth following a posssible intrusive injury. The condition analysed in this study belong to a patient who visited our Children's Dentistry Clinic. These conditions are often overlooked by parents mainly because less attention is given to the primary dentition and to the child's inability to cope with the situation. The earlier this kind of condition is diagnosed, the less would be the destructive effects and the consequences on the permanent germ unit.
