Aim: The present study is conducted to explore knowledge and attitude regarding periodontal diseases among dental undergraduate students.Material and Methods: This is a descriptive cross-sectional questionnaire study. Samples are undergraduate students of third year, fourth year and internship students. Students who are present on the day of study was included in the study and given there informed consent.Results: Majority of study subjects among all study participants knows the meaning of periodontal diseases {207(72%)}. Most of the study participants {158(55%)} told that the vitamin C deficiency, poor oral hygiene and injury to gums all are main cause of periodontal diseases. Most of the study participants {192(66%)} were agrees with the fact that periodontal diseases are very hazardous for teeth. Most of the undergraduate students {189(65%)} were agree with the fact that periodontal diseases in its early cannot be ignored. Periodontal diseases can affect general health was agreed by most of study participants {151 (52%)}.Conclusions: Based on above results it was revealed that the well-educated dental professionals who are going to become the foundation of future dentistry had a fair knowledge and positive attitude regarding the periodontal diseases.

Internal root resorption has been described as a resorptive defect of the internal aspect of the root following necrosis of odontoblasts as a result of chronic inflammation and bacterial invasion of the pulp tissue. Successful treatment outcome depends on early diagnosis, removal of the cause, proper treatment of the resorbed root. The present case report demonstrates the use of biodentine for the management of internal resorption.he aim of this study was to evaluate the efficacy of different lengths of time of passive ultrasonic irrigation (PUI) in removing calcium hydroxide (CH) paste from root canal, using scanning electron microscopy and energy dispersive spectrometry (SEM/EDS).

Background: Internal anatomy of maxillary first premolars is particularly multifaceted on account of the variation in number of roots and canal configuration. Maxillary first premolars with 3 roots are called as small molar or “radiculous” because of their similar anatomy to the maxillary first molars. The most demanding step in endodontic treatment is identification and proper access to pulp canals of certain teeth with atypical canal configurations. Methods of identification of such premolars can be by various aides.Case Presentation: The present case describes the application of Cone Beam-Computed Tomography in the diagnosis of extra root with extra canal in a three rooted maxillary right first premolar.Conclusions: Proper knowledge of the anatomical variations is a must for an endodontist to make a treatment successful. Utilizing the latest technology along with the traditional concepts can surely rule out the inaccuracy in the treatment involved in such cases.
