The authors conducted a systematic review of randomized controlled trials comparing the risk of experiencing restoration failure in primary teeth after complete and selective carious tissue removal of soft dentin.
The authors searched electronic databases (PubMed [MEDLINE], Scopus, Cochrane Central Register of Controlled Trials) and the ClinicalTrials.gov Web site with manual searching and cross-referencing for trials reporting restoration failure after follow-up of 6 months or longer. Two reviewers independently selected studies, extracted data, and assessed the risk of bias and quality of evidence using the Grading of Recommendations Assessment, Development, and Evaluation approach. The authors performed intention-to-treat and per-protocol meta-analyses and calculated odds ratios (OR) as effect estimates in the random-effects model.
From 327 potentially eligible studies, the authors selected 23 for full-text screening and included 4. Results showed increased risk of experiencing restoration failure (intention-to-treat analysis, OR [95% confidence interval] 1.74 [1.01 to 3.00], and per-protocol analysis, OR [95% confidence interval] 1.79 [1.04 to 3.09]) after selective carious tissue removal of soft dentin. The risk of bias was high, and the quality of evidence was low.
Selective carious tissue removal of soft dentin may increase the risk of experiencing restoration failure in primary teeth. However, the evidence level is insufficient for definitive conclusions.
Patients with restorations performed after selective carious tissue removal of soft dentin should have shorter recall visit intervals to evaluate the restorations’ quality and control caries disease, allowing for more conservative approaches, such as repair, in cases of defective restorations.
Periodontitis has been hypothesized as being one of the most common potential risk factors for the development of dementia and cognitive impairment. In order to investigate the relationship between periodontitis and cognition impairment, the National Health and Nutrition Examination Survey (NHANES) database was analyzed after adjusting for potential confounding factors, including age and other systemic co-morbidities.
MATERIALS AND METHODS:
In total, 4663 participants aged 20 to 59 years who had received full mouth periodontal examination and undergone the cognitive functional test were enrolled. The grade of periodontal disease was categorized into severe, moderate, and mild. Cognitive function examinations, including the Simple Reaction Time test (SRTT), Symbol Digit Substitution Test (SDST), and Serial Digit Learning Test (SDLT), were adopted for the evaluation of cognitive impairment.
The subjects with mild and moderate to severe periodontitis had higher SDLT and SDST scores, which indicated decreased cognitive function, compared to the healthy group. After adjusting for demographic factors, education, smoking, cardiovascular diseases, and laboratory data, periodontitis was significantly correlated with elevated SDST and SDLT scores (P values for trend = 0.014 and 0.038, respectively) by generalized linear regression models.
Our study highlighted that periodontal status was associated with cognitive impairment in a nationally representative sample of US adults.
Materials and methods
Our objectives were to describe the approach used in the National Dental Practice‐Based Research Network to capture patient‐reported outcomes and to compare electronic and paper modes of data capture in a specific network study.
This was a prospective, multicenter cohort study of 1862 patients with dentin hypersensitivity. Patient‐reported outcomes were assessed based on patients’ perception of pain using Visual Analog Scales and Labeled Magnitude scales at baseline and at 1, 4 and 8 weeks post‐baseline.
Eighty‐five percent of study patients chose to complete follow‐up assessments via an electronic mode; 15% completed them via a paper mode. There was not a significant difference in the proportions of patients who completed the 8‐week assessment when comparing the electronic mode to the paper mode (92% vs. 90.8%, P = 0.31, Rao‐Scott clustered χ2‐test).
The electronic mode of data capture was as operational as the traditional paper mode, while also providing the advantage of eliminating data entry errors, not involving site research coordinators in measuring the patient‐reported outcomes, and not incurring cost and potential delays due to mailing study forms. Electronic data capture of patient reported outcomes could be successfully implemented in the community dental practice setting.
