Root surface caries among older Australians

Changes in Gloss Alteration, Surface Roughness, and Color of Direct Dental Restorative Materials after Professional Dental Prophylaxis

In the context of optimizing dental care for patients who are elderly, the purpose of this in vitro study was to evaluate the surface gloss (with a micro-area gloss meter) of, surface roughness (with a compact surface roughness measuring instrument) of, and color change (with a dental colorimeter) in two commercially available injectable resin-based composites (Estelite Universal Flow (EUF) and Beautifil Flow Plus F00 (BFP)) as well as two glass-ionomer cements (GC Fuji II LC CAPSULE (FLC) and GC Fuji IX GP EXTRA CAPSULE (FGP)), before and after dental prophylaxis. After 24 h, the surfaces of each specimen were polished at 2500 rpm with a prophy brush (Mersage Brush, Shofu) and one-step prophylaxis paste (Prophy Paste Pro, Directa): under 100 or 300 gf load, and for 10 or 30 s, 4× cycles of cleaning. After mechanical cleaning, conditions were found for a significant reduction in the gloss level (EUF, BFP, or FLC; p < 0.05) and a significant increase in surface roughness (BFP; 300 gf load, 10 s × four cycles of cleaning). Overall, the longer time or higher prophylaxis load tended to decrease the surface gloss. However, the observed change in surface roughness varied between the restorative materials. There was no color change post-prophylaxis.

Contextual and local determinants associated with the achievement of goals in the endodontics specialty in Brazilian dental speciality centres: A multilevel analysis

OBJECTIVES

To assess which factors were associated with the achievement of endodontic goals.

METHODS

Cross-sectional study using secondary data from the second cycle of the Program for the Improvement of Access and Quality in the dental speciality centres-in Portuguese PMAQ-CEO. The independent variables extracted from this database were related to dental speciality centres (CEO in Portuguese). In addition, variables referring to the CEO host city were incorporated into the model. The outcome variable was the number of endodontic goals achieved calculated from the production of the CEO available in the Ambulatory Health Information System in 2018. Descriptive analyses and multilevel Poisson regression were performed with the software SPSS 23.0 and STATA 14.0.

RESULTS

CEOs with more than 20% of patients' absenteeism were 26% less likely to reach the goals of the endodontics specialty; CEOs with availability of endodontists for more than 40 hours a week were two times more likely to reach the goals than those with less than 40 hours in endodontics specialty. CEOs with a waiting time for endodontic procedures greater than 45 days achieved a number of goals 31% lower than those with a waiting time up to 45 days. CEO type I and CEO type II showed 2.10 and 1.20 higher likelihood to reach the number of goals of the endodontics specialty than CEO type III. The number of endodontic instruments in sufficient number was positively associated with the achievement of goals. CEOs located in municipalities that reached more than 5% in the supervised brushing indicator had 2.26 greater likelihood to achieve the goals than those that did not reach this percentage.

CONCLUSION

Contextual and local determinants are associated with the achievement of goals in the endodontic specialty in the dental speciality centres in Brazil.

Factors associated with development of root caries in dentition without root caries experience in a 2-year cohort study in Japan

OBJECTIVES

To investigate factors associated with the development of root caries in dentition without root caries experience and interactive relationships between risk factors.

METHODS

We conducted surveys, consisting of an oral examination (oral hygiene, assessment of the number of teeth, coronal and root caries) and a self-reported questionnaire, among employees of a company in Tokyo, Japan in 2016 and 2018. Questionnaires collected data on smoking status, oral hygiene habits, sugar intake, and frequency of dental visits. Multiple logistic regression and decision tree analyses were used to determine factors associated with the development of root caries.

RESULTS

A total of 299 participants aged 25-63 years were included in the analysis. Males, older adults, smokers/past smokers had a significantly greater risk of developing root caries. The risk of developing root caries was significantly associated with the number of teeth with gingival recession at baseline (6-9 teeth, odds ratio [OR]: 7.69, 95 % confidence interval [CI]: 2.31-25.56; 10+ teeth, OR: 9.19, 95 % CI: 2.73-30.95, relative to ≤5 teeth); and with the number of coronal decayed and filled (DF) teeth (11-13 teeth, OR: 3.21, 95 % CI: 1.12-9.24; and ≥14 teeth, OR: 3.60, 95 % CI: 1.27-10.20, relative to ≤10 teeth). Other factors associated with root caries development differed according to the number of teeth with gingival recession and included drinking sugar-sweetened beverages, and the amount of toothpaste used.

CONCLUSIONS

Gingival recession and number of coronal DF teeth were associated with the development of root caries.

CLINICAL SIGNIFICANCE

Multiple factors are associated with root caries development. The effect of risk factors such as drinking sweetened beverages and less toothpaste use is greater in individuals with greater gingival recession and more coronal decayed and filled teeth. Dental practitioners should focus on modifiable risk factors to prevent root caries.
