Commonly used irrigants do not always eradicate the entire microbial flora in infected root canals. Therefore, several other strategies, such as photodynamic therapy (PDT) have been developed. Photoactivated disinfection is based on the interaction of a photosensitive antibacterial agent and a light source. It uses a nontoxic dye named photosensitizer (PS) and low-intensity visible light. In oxygen presentation, these combine to produce some cytotoxic species. The PS molecules attach to bacteria membrane. Irradiation with a specific wavelength of the light may lead to the production of singlet oxygen, resulting in rupture of the microbial cell wall...

INTRODUCTION: Chronic apical periodontitis (CAP) manifests mostly as periapical radiolucency. Various inflammatory mediators play a significant role in the pathogenesis of apical periodontitis. In acute inflammatory conditions, C-reactive proteins (CRP) and fibrinogen show a rise in their concentrations. In chronic diseases with high inflammatory components, an increased prevalence of hypertension has been observed. Hence, we assessed the association of CAP and plasma levels of various inflammatory markers (CRP, interleukin 6 [IL-6], and fibrinogen) in severely hypertensive patients...

INTRODUCTION: One of the common findings encountered by the clinician at the end of orthodontic treatment is the apical root resorption. Root resorption occurs to various degrees. A severe form of root resorption is characterized by shortening of root for more than 4 mm or more than one-third of the total tooth length. A low incidence rate of resorption is observed based on radiographic findings for the diagnosis of root resorption, panoramic radiography, and periapical radiography. Hence, we evaluated the accuracy of panoramic radiographic films for assessing the root resorption in comparison with the periapical films...
