Abstract

The changes in the pattern of bacteria in root canal after repeated washing with NaOCl and endodontic instrumentation were evaluated. Samples were obtained from the root canals of patients before and after endodontic instrumentation, and analyzed according to the usual microbiological techniques. Washing with NaOCl and endodontic instrumentation act against bacteria such as Peptostreptococci, Streptococcus sanguis, Actinomyces israelii, Proteus mirabilis, Bacteroides, whereas Streptococcus lactis and Aerococcus were present before and after endodontic instrumentation. Environmental conditions such as low pH could be responsible for the persistence of gram-positive bacteria. The use of topical treatment and the associated endodontic instrumentation seem useful in the eradication of some bacteria in the root canal.

A comparative evaluation of self-reported oral hygiene practices among medical and engineering university students with access to health-promotive dental care.

AIM: This study was conducted to test the null hypothesis that no difference exists in the oral hygiene knowledge and practices of university students in different courses when they have equal opportunity to access health-promotive dental care. METHODS AND MATERIALS: The study was conducted using 120 students each from the medical and engineering colleges at the University of Manipal Academy of Higher Education who had easy access to the dental college within the campus which provides health-promotive dental care to all its patients. A self-administered structured questionnaire consisting of questions on demographic data, oral hygiene knowledge and practices, and dental service utilization patterns was distributed among the students. The data collected was analyzed using SPSS 10 version. RESULTS: Statistically significant differences were found between the two groups with respect to the knowledge of fluoridated toothpastes, frequency of toothbrush renewal, use of dental floss, and a tongue cleaner (p < 0.001). The groups were similar in all other practices including the utilization of dental services. There were no significant differences between the self-reported oral hygiene knowledge and practices among medical and engineering university students, but the knowledge levels of the students were considerably lower than expected.

Pierre Fauchard: the 'father of modern dentistry'.

The development of the modern practice of dentistry can be traced to the work and life of Pierre Fauchard, a French dentist who worked in the first half of the eighteenth century. Fauchard was an exceptionally gifted and talented practitioner, who introduced many innovations to dentistry. In a significant break with the tradition of the time, he shared his knowledge and techniques with colleagues, and published these in the first comprehensive dental textbook. This paper reviews his life and contribution to modern dentistry.
