Root caries patterns and risk factors of middle-aged and elderly people in China

Abstract –  The objectives of this study were to describe root caries patterns of Chinese adults and to analyze the effect of selected demographic and socioeconomic factors on these patterns. A total sample of 1080 residents aged 35–44-years-old and 1080 residents aged 65–74-years-old from three urban and three rural survey sites in Hubei Province participated in both an oral health interview and a clinical oral health examination. Root surface caries prevalence rates were 13.1% in the middle-aged group and 43.9% in the elderly group. The mean number of teeth affected by caries in the middle-aged group was reported at 0.21 and 1.0 in the elderly group. Mean Root Caries Index (RCI) scores of the middle-aged were reported at 6.29 and elderly subjects were reported at 11.95. Elderly people living in rural areas reported a higher RCI score (13.24) than those living in urban areas (10.70). A significantly higher frequency of root surface caries was observed in elderly participants ( P  < 0.001, OR = 3.80) and ethnic minorities ( P  < 0.001, OR = 1.93). In addition, smokers, nontea drinkers, and those with an annual household income of 10 000 yuan or less tended to have higher caries prevalence. RCI figures for the different tooth types ranged from 1% to 16%, indicating a wide variation in attack rates. In conclusion, our study suggests that root surface caries occurrence is high among the Chinese adult population, especially older adults. With an increasing number of retained teeth in both middle-aged and elderly people, root caries is a growing disease in the People's Republic of China which deserves more attention in future research.

Real-time polymerase chain reaction quantification of human cytomegalovirus and Epstein-Barr virus in periodontal pockets and the adjacent gingiva of periodontitis lesions

BACKGROUND: Genomic sequences of human cytomegalovirus (HCMV) and Epstein-Barr virus (EBV), two herpesviruses, can frequently be detected in periodontal pockets of progressive periodontitis lesions, but the prevalence and load of the two viruses in gingival tissue are unknown. This study determined levels of HCMV and EBV DNA in the periodontal pocket and in the adjacent gingiva of periodontitis lesions using a real-time polymerase chain reaction (PCR) assay. MATERIAL AND METHODS: A total of 20 systemically healthy periodontitis patients participated in the study. Nine patients below 35 years of age were tentatively diagnosed as having aggressive (early onset) periodontitis, and 11 patients 36-56 years of age as having chronic (adult) periodontitis. Clinical parameters were evaluated using established methods. Using periodontal curettes, specimens were harvested from 6-10 mm periodontal pockets and from the adjacent inflamed periodontal pocket wall. A 5'-nuclease (TaqMan) real-time PCR assay was used to identify and quantify genomic copies of periodontal HCMV and EBV. RESULTS: HCMV DNA was detected in 78% of subgingival and 33% of gingival tissue samples from aggressive periodontitis lesions, but only in 46% of subgingival and 9% of gingival tissue samples from chronic periodontitis lesions. In aggressive periodontitis, HCMV subgingival and gingival tissue counts were positively correlated with periodontal pocket depth and probing attachment loss at sample sites (p6 mm, but none of 14 patients having mean pocket depth at sample teeth相似文献   

The effect of periodontal disease on medical and dental costs in a middle-aged Japanese population: a longitudinal worksite study

BACKGROUND: Although periodontal disease is one of the most common chronic diseases, it is not clear whether periodontal disease is associated with increased health care costs. The authors examined the effect of periodontal disease on medical and dental costs and use for 3.5 years prospectively. METHODS: The data were derived from health and dental examinations and health insurance claims of 4,285 Japanese civil officers aged 40 to 59 years. The subjects were divided into three categories: no pathological pocket, moderate periodontitis, and severe periodontitis. Age, gender, smoking, body mass index, and hypertension were adjusted in a multivariate analysis after excluding subjects with any history of liver disease, heart disease, or diabetes mellitus. RESULTS: The cumulative cost for subjects with severe periodontitis was approximately 21% higher than for subjects with no pathological pocket, and the hospital admission rates of subjects with severe periodontitis were highest (male: odds ratio [OR]=.34; 95% confidence interval [CI]: 1.00 to 1.80; female: OR=1.29; 95% CI: 0.75 to 2.20). In males, the annual hospital costs of subjects with severe periodontitis were 75% higher than for subjects with no pathological pocket. There was no clear trend identified for outpatient care. The annual dental visit rates and costs for subjects with severe periodontitis were highest in both genders. Periodontal disease might increase the medical care costs for diabetes mellitus, digestive disease, and liver disease. CONCLUSION: Periodontal disease may have played an important role in the cumulative health care cost increases in middle-aged adults over a period of only a few years.

Oral health conditions and denture treatment needs in institutionalized elderly people in Japan

Oral health conditions, including dental conditions, temporomandibular joint (TMJ) conditions, denture status, and oral hygiene status, were assessed on 1908 institutionalized elderly people 65 yr of age and older at 29 of the 30 existing institutions in the city of Kitakyushu, Japan. The percentage of edentulous people was 27% in the 65-74-yr-old group, and increased with age to 56% in the 85 yr and older group. In dentate persons, the mean number of remaining teeth and DF teeth were 13.4 and 8.6, 9.5 and 6.8, and 8.4 and 6.5 in the groups aged 65-74 yr old, 75-84 yr old, and 85 yr and older, respectively. 81% of all the persons examined had no unusual symptoms in their TMJ. A clicking sound was the most frequent symptom (17%). Hygiene of both their teeth and dentures was very poor. Of all the subjects, 36% needed new full and/or partial denture(s), and 41% needed only repair. When the institutionalized elderly people were compared according to their general health condition, no clear differences were observed in percentage of edentulousness, mean number of remaining teeth and DF teeth, and TMJ conditions. However, a higher level of both untreated teeth and denture treatment needs, and poorer oral hygiene, was found in elderly people having poor general health than was observed in those with better health.(ABSTRACT TRUNCATED AT 250 WORDS)     

Association of T CD4 lymphocyte levels and subgingival microbiota of chronic periodontitis in HIV-infected Brazilians under HAART

OBJECTIVE: The aim of this study was to determine the subgingival microbiota of HIV-infected patients with chronic periodontitis and different T CD4 lymphocyte levels under HAART. STUDY DESIGN: 64 HIV+ patients (mean age 34.5 +/- 7.3; 75% males) were distributed into Group I: chronic periodontitis (> or = 3 sites with probing pocket depth (PPD) and/or clinical attachment level (CAL) > or = 5 mm); and Group II: periodontal health (no sites with PPD > 3 mm and/or CAL > 4 mm). All subjects received conventional periodontal therapy. Periodontal clinical parameters were evaluated at 6 sites/tooth in all teeth at baseline and 4 months after therapy. The levels of T CD4 were obtained from the patient's medical record. Subgingival plaque samples were taken from the 6 sites with the largest pocket depth in each subject of Group I, and 6 randomly selected sites in subjects of Group II. The presence of 22 subgingival species was determined using the checkerboard DNA-DNA hybridization method. Significant microbiological differences within and among groups were sought using Wilcoxon signed-rank and Mann-Whitney tests, respectively. Relationships between T CD4 levels and microbiological parameters were determined using Kruskal-Wallis test. RESULTS: Sixty-one percent of the HIV-infected patients represented AIDS cases, although 69% of them were periodontally healthy. The T CD4 lymphocyte mean level was 333 cells/mm3 and viral load was 12,815 +/- 24,607 copies/mm3. Yet, the prevalence of chronic periodontitis was relatively low (36%). Several periodontal pathogens, in particular T. forsythensis (P < .05), were more prevalent in HIV-positive patients with periodontitis than in HIV-positive subjects with periodontal health. Most of the species decreased in frequency after therapy, particularly P. gingivalis (P < .05). E. faecalis and F. nucleatum were significantly more prevalent in the subgingival microbiota of patients with chronic periodontitis and lower levels of T CD4 (P < .05), while beneficial species tended to be more frequently detected in individuals with T CD4 counts over 500 cells/mm3. CONCLUSION: The subgingival microbiota of HIV-infected patients with chronic periodontitis include a high prevalence of classical periodontal pathogens observed in non-infected individuals. Furthermore, the severe immunosuppression seems to favor the colonization by these species, as well as by species not commonly found in the subgingival microbiota.
