The samples of dental deposit plaque collected from 30 people in the faculty of Natural Science were stained by Gram technique. A bacterial prosperious component was detected including Gram (+) cocci, Gram (-) cocci, red and thin cell, red and long cell, straight and curved Gram (-) cells, thin spinal cells … Microorganism population on the deposit plaque under the gun includes bacteria, cocci, and spirochaetes. 3 genera were determined including Streptococcus, Lactobacillus and Actinomyces, with a highest incidence of Streptococcus. The representative genus has the characteristic similar to Streptococcus mutans and it seems that it plays an important role leading to caries

The finding revealed that the majority of the mothers had a high and moderate level of knowledge and attitude towards dental health. Around two-thirds of the mothers had good dental health preventive behavior (62.7%). Among them 71.3% of the mothers brushed their children's teeth two to three times a day, and 76.0% cleaned their children's teeth after meals. Most of the mothers used fluoride toothpaste to brush their children's teeth (86.0%). However, misconceptions still existed. More than two-thirds of the mothers didn't know the advantage of pit and fissure sealant; the appropriate time to brush their children's teeth, and the effect of Tetracycline on their child's teeth. Only 32.7% of the mothers brought their child to see the dentist for check-up and 15.3% did so at an appropriate time which was every six months. Television was the most frequent source of information about dental health that the respondents were exposed to (89.3%). The result of the study showed a significant association between knowledge of dental health and dental health preventive behavior (P = 0.031) and the level of mother's education and dental health preventative behavior (P = 0.033).

The program of school-based oral care has been organised at all 25 primary and secondary schools of Gia Loc district since 1989/1990 to prevent oral diseases that include gingivitis. After 8 years, the ratio of children who affected by gingivitis reduced clearly. The rate of school pupils who have acceptable gingival health increased from 8.42% to 94.21%. This result confirms that school-based oral preventive activities are neccesary and suitable. Particularly, in 1997/1998 we reaches WHO and EEC countries’s goal as well as Vietnam’s goal for the year of 2010

Clinical evaluation for a successful root canal treatment is assessed by various criteria, which are clinical, histopathological, and radiographical criteria. Therefore, failure of endodontic treatment can be described as a recurrence of clinical symptoms, with the presence of a periapical radiolucency or both. Failure factors in the treatment are frequently related to persistent infection. Conventional endodontic retreatment is indicated for symptomatic previously treated teeth or asymptomatic teeth with inadequately done initial endodontic treatment to avoid potential recurrence. Endodontic retreatment in elderly patients is a great challenge because the clinician has to reassure both the physical and psychological factors of the patient to determine whether to save a tooth or perform an extraction. Some difficulties may also be found in root canal retreatment, including finding the root canal hole or root canal blockage found in parts of the root canal that have not been repaired in the previous treatment. A 60-year-old female patient came with the chief complaint of recurrent pain, and subjective discomfort in the maxillary left central incisor. The patient had anxiety about the dental treatment. The tooth had a history of root canal treatment four months ago. The clinical examination showed a positive response to the percussion test. The radiographical analysis showed a root canal underfilling, 2-3 mm short of length from the apex. The tooth was diagnosed as a previously treated tooth with symptomatic apical periodontitis. Endodontic retreatment was performed based on the patient’s clinical condition and consent, followed by composite restoration. The clinical and radiographic re-evaluation after four weeks of follow-up revealed an excellent condition. This favorable result showed that a conventional retreatment plan of persistent pain on the previously treated tooth in an elderly patient led to progressive healing, and a longer follow-up was advised.
