ABSTRACT
AIM: Aim of the study was to correlate CD4 counts with oral and systemic manifestations in HIV patients. MATERIALS AND METHODS: Study population comprised of newly diagnosed 100 confirmed seropositive patients, before starting any antiretroviral therapy, were included. The oral lesions were diagnosed based on clinical manifestation using international criteria and CD4 count was determined within maximum 1 week of oral examination. Oral and systemic manifestations of HIV-positive patients were recorded and correlated with CD4 counts. RESULTS: It was found that decrease in CD4 count is associated with a wide range of oral and systemic manifestations which can be used as prognostic marker for immune suppression in AIDS patient. CONCLUSION: Correlation of CD4 count with oral and systemic manifestation in HIV patient demonstrate the role of oral physician in identification, diagnosis, and treatment of HIV-associated lesions, providing proper guidance to the patient and allowing for an early diagnosis and treatment of the disease, which is fundamental for a successful management of the life conditions of HIV infected patients.
ABSTRACT
OBJECTIVES: The aim of this study was to compare the shaping ability of three file systems - 2Shape (2S), WaveOne Gold (WOG), and ProTaper Gold - using cone-beam computed tomography (CBCT). MATERIALS AND METHODS: Forty-five freshly extracted mandibular teeth were chosen and instrumented using the following brands of NiTi files: 2S, WOG, and ProTaper Gold. Pre- and post-instrumentation CBCT imaging was performed to measure mesial and distal distance of the dentin walls and calculate the volume of removed dentin, apical transportation, and centering ratio. A statistical analysis of the data was performed using independent t-test. Statistical significance was set at 5%. RESULTS: There were no significant differences between the 2S and WOG in terms of the total volume of removed dentin, apical transportation, and centering ratio, whereas ProTaper showed a greater significant difference when compared to 2S and WOG. CONCLUSION: Both 2S and WOG maintained the original canal anatomy better and did not remove excess dentin while chemomechanical preparation as compared to ProTaper Gold. Instruments that use rotary movement achieved an effect similar to that of the reciprocating instruments in relation to change in angle. 2S which is a two-file system and WOG which is a single-file system might perform better clinically and might show enhanced shaping ability with less canal transportation and more centered preparation when compared to ProTaper Gold that is a multiple file-system.
