Chitosan, a versatile hydrophilic polysaccharide derived from chitin, has a broad antimicrobial spectrum to which gram-negative, gram-positive bacteria and fungi are highly susceptible.The chitosan minimum inhibitory concentrations (MIC) are summarized according to recent data found in the literature. In the current review the possible applications ofchitosan in dentistry are briefly discussed

The main objective of non-surgical root canal treatment is the thorough chemomechanical debridement of the entire pulp space cavity and its complete obturation with an inert filling material [1]. Since the work of Hess and Zurcher[2], it has become apparent that the pulp cavity comprises a complex network of anatomical structures and knowledge of this complex internal dental morphology is an extremely important step in planning and administering endodontic therapy because nontreatment of even one canal can lead to endodontic treatment failure.[3]

Chronic renal disease is defined as a progressive and reversible decline in the renal function associated with a reduced glomerular filtration rate (GFR).In addition to their associated morbidity, such disorders are important due to the number of affected individuals and the many patients subjected to treatment because of them. An inadequately controlled CRD patient constitutes a risk case in Orthodontic practice due to greater bleeding tendency, hypertension, anaemia, drug intolerance, increased susceptibility to infections. Orthodontic practitioners therefore must take a series of aspects into account before treating such patients, in order to avoid complications. This paper is a review of the general aspects of renal diseases, oral manifestations,dose adjustments of drugs,orthodontic considerations and their management.

Bisphosphonate has been the drug of choice for the patients who have bone related pathologies like osteoporosis, Paget's disease, metastasis of bone cancers etc. Though these classes of drugs have been successful in treating and curing such pathologies but still it has got its side effects. Studies have shown that patients taking bisphosphonates are prone to develop osteonecrosis of jaws. This side effect of bisphosphonate make it must for a prosthodontist to take a different protocol for treating a patient receiving bisphosphonate drugs. This article aims at reviewing the literature on how to manage patients taking bisphosphonates for both removable and fixed prosthesis.

Introduction – LED lights have been successfully used to enhance the polymerization of photosensitive restorative materials and to shorten the curing time without compromising bond strength. Bond strength should be sufficient to withstand the masticatory forces and be low enough to allow for bracket debonding without causing damage to the enamel surface. Aim and objectives – To compare the effect of different light cure systems on shear bond strength (SBS) of bonded orthodontic brackets at different exposure times. Materials and method – 100 extracted human premolar teeth were randomly divided into 2 groups according to 2 different light sources, i.e. Group I (Halogen), Group II (Coltolux LED) which were further subdivided into two subgroups on the basis of various exposure times (10sec, 15sec). After bonding procedure, the teeth were subjected to SBS testing by Instron machine. ANOVA and Tukey analysis done for adequate comparisons between different groups and subgroups. . Results – The mean SBS obtained for Group II > Group I for the 2 exposure times. Maximum SBS was noted for both the groups at 15sec. Mean SBS obtained with Coltolux and Halogen at 15sec was found to be within the clinically acceptable range. Statistically significant difference (p<0.001) was obtained at 15sec only. Conclusions – Though bond strength increases with the increase in curing time but clinically acceptable SBS can be obtained at 15 sec with Coltolux which confers worthwhile time savings with lower risk of contamination. Hence, using higher light intensity of acceptable wavelength for curing produces same SBS with much shorter exposure time.
