Assistant Professor of Chemistry, Medical College, Calcutta, The dried pulp of the mango (Mangifera Indica) contains such a large amount of Citric Acid as to make this common fruit not at all an inefficient substitute for lime-juice when the latter cannot readily be obtained as an antiscorbutic. A quantitative analysis of three different samples of mango-pulp, which had been dried by exposure t...

The dental pulp is characterized as a connective tissue and as such it is not considered an external tissue, yet its exposure to external stimuli is constant. This is due to a number of factors including the permeability of attrited or disrupted enamel as well as that of physiologic dentin and cementum. The pulp is extraordinarily sensitive to its external environment. Once thought to be a vest...

INTRODUCTION Differentiation between reversible pulpitis (savable pulp) and irreversible inflammation of the pulp tissue (nonsavable pulp) based only on clinical and radiographic diagnoses has proven to be difficult. Pulp exposure allows for the collection of pulpal blood to quantitatively determine the level of inflammation markers or proteolytic enzymes, even with small samples. Pulpitis is a...

OBJECTIVE To develop an aerosol exposure method for induction of brucellosis in rhesus macaques (Macaca mulatta). ANIMALS 10 adult rhesus macaques. PROCEDURE 8 rhesus macaques were challenge exposed with 10(2) to 10(5) colony-forming units of Brucella melitensis 16M by use of an aerosol-exposure technique, and 2 served as control animals. All macaques were euthanatized 63 days after challen...

Purpose: To evaluate the available evidence on pulp capping procedures and root canal treatment in young permanent teeth with vital pulps exposed by caries. Methods: The study was conducted as a systematic review of the literature. Three databases, PubMed, Web of Knowledge, and The Cochrane Library were searched. Reference lists of relevant articles were hand searched. The quality of all releva...

Our objective in this study was to evaluate the mortality of workers exposed to sulfur dioxide in the pulp and paper industry. The cohort included 57,613 workers employed for at least 1 year in the pulp and paper industry in 12 countries. We assessed exposure to SO(2) at the level of mill and department, using industrial hygiene measurement data and information from company questionnaires; 40,7...

introduction: the aim of this randomized clinical trial was to compare the histologic pulp tissue response to one-step direct pulp capping (dpc) and miniature pulpotomy (mp) with mineral trioxide aggregate (mta) after application of dexamethasone in healthy human premolars. methods and materials: forty intact premolars from 10 orthodontic patients, were randomly chosen for dpc ( n =20) or mp ( ...

Biocompatibility of dentin bonding agents (DBA) and composite resin may affect the treatment outcome (e.g., healthy pulp, pulpal inflammation, pulp necrosis) after operative restoration. Bisphenol-glycidyl methacrylate (BisGMA) is one of the major monomers present in DBA and resin. Prior studies focused on salivary esterase for metabolism and degradation of resin monomers clinically. This study...

Studies on dental regeneration involving interventions for pulp therapy such as regeneration and revascularization procedures are promising for the injured tooth; however, a complete replication of the original pulp tissue does not seem to take place. In cases in which we wish to preserve or maintain parts of the pulp during treatment, it is apparent that the effectiveness of healing or biologi...

Deep dentinal lesion progress is often presented as the point of no return for the specific pulp involved. In these lesions, however large variations and changes within the lesion environment may be detected. As the disease process is better studied and understood, more conservative treatments have come 5 up in the treatment of deep carious lesions. One such is a step-wise excavation procedure,...
