ABSTRACT
Background Smoking is one factor which can alter the folic acid, vitamin B12 and blood cell parameters. The aim of this study was to compare the levels of folic acid, vitamin B12 parameters in smokers as compared with healthy controls. Materials and Methods Totally, 50 patients between the age group 25 and 65 years were recruited for the present study. They were grouped as group I-healthy subjects-and group II-subjects who smoke. Five millilitres of venous blood were collected from all the subjects and submitted for haematological analysis. Results Significant lower levels of folic acid and vitamin B12 levels were noticed in smokers’ subjects. Conclusion The result of the present study signifies that folic acid and vitamin B12 levels are significantly lower in smokers. Smoking has an impact on the folic acid and vitamin B12 levels.
ABSTRACT
Background Root conditioning agents reveal the orifices of dentinal tubules and the dentin collagen matrix and provide a substrate which plays a role chemotaxis migration and proliferation of cells involved in periodontal healing and formation of new connective tissue attachment. Materials and methods A total of 15 extracted teeth which were periodontally involved were utilised for the study. All the teeth received 25% citric acid application. The samples were subjected to scanning electron microscope evaluation. The photomicrographs were analysed by image software analyser to assess its surface area. Results Group II showed better results for mean surface area. Conclusion: These results show that citric acid could be a better healing biomaterial in periodontal regeneration by increasing surface area.
ABSTRACT
Gross tissue evaluation of a pathology specimen forms an indispensable but often neglected component for complete pathologic evaluation along with microscopic examination. Macroscopic features are helpful in the differential diagnosis of various cases, which are of challenge. The gross features of the surgical specimen have to be properly examined and documented at the initial setup because once the specimen is dissected and taken for processing it is unsuitable for gross examination. Therefore, the gross or the macroscopic description remains the only document later which can provide an important clue for diagnosis. The purpose of this present article is to provide adequate insight into the gross examination and description of the surgical specimen and to review the macroscopic features of various pathologies.
ABSTRACT
As with all emerging technologies, a successful future for nanotechnology will only be achieved through open sharing of ideas and research findings, through testing and frank discussion. Time, advances, resources, and needs will determine which prospects becomes reality. Application of nanotechnology to all branches of dentistry will soon be a reality. So get ready for smart nanotech dentistry.
