Hepatitis B virus infection in dentists and dental students in Greece.

The prevalence of hepatitis B virus (HBV) markers in 416 dental students, 115 dentists, and 329 members of the general population was studied in Athens. Markers were present in 36 students (8.7%), 34 dentists (29.6%), and 74 controls (22.5%). Four students (1.0%), 3 dentists (2.6%), and 6 controls (1.8%) were carriers of hepatitis B surface antigen (HBsAg). The prevalence of HBV infections increased with age significantly faster in the dental profession than in the general population, showing an increased risk. Of 22 dentists in practice for more than 20 years, 12 (54.5%) had HBV markers and 4 (18.2%) reported a clinical hepatitis infection. These data show that members of the dental profession should also be included in the national hepatitis B vaccination program.

Pattern of tooth loss in a selected population in Greece.

The pattern of tooth loss with age for individual teeth was examined in a selected population. The survey covered patients attending the Dental School of Athens University. Tooth loss increased steadily with age and was higher for the periodontitis than the gingivitis group. Mortality of individual teeth was analyzed for each type of tooth within the maxillary pair and within the mandibular pair and no statistical significance was found. The statistically highly significant differences in loss rates within most groups of four teeth were clearly attributable to differences between the maxilla and mandible. For the permanent second molars differences in loss were close to the significance level while for the first molars the difference was statistically highly significant. A statistically significant difference was found between losses of the four second premolars while highly significantly differences were noticed between first premolars. Mortality for canines was low, but differences in losses were highly statistically significant. The two mandibular incisors had the lowest rates of loss in our sample, difference in loss between maxillary and mandibular incisors was statistically highly significant. Central incisors had a similar pattern of loss to that of lateral incisors but differences in loss rates were not statistically significant.

Microbiological findings of infected root canals and adjacent periodontal pockets in teeth with advanced periodontitis.

The purpose of the present study was to examine the flora from the root canals and periodontal pockets of teeth with advanced periodontal disease in order to compare the predominant cultivable microflora from the canals with those found in the adjacent periodontal pockets. Three samples were collected from each of sixteen patients, one from the root canal and two from the adjacent periodontal pocket in two different sites. Criteria for inclusion in the survey were pocket depth of greater than or equal to 7 mm, intact clinical crowns, and lack of periapical lesions. The study has demonstrated that the microorganisms present in the root canals of caries-free teeth with advanced periodontitis generally resembled those found in the adjacent periodontal pockets. The similarity in the recovery of organisms in the current study suggests that the pocket could be the source of the root canal infections. Further investigation is needed to clarify whether such factors as duration of periodontitis and age of the patient play a role in pulpal pathosis and whether the presence of specific bacterial species is also a factor in the etiology and pathogenesis of pulp disease.
