Background
Silver diamine fluoride (SDF) is used topically to prevent or arrest caries. The authors' aim was to characterize the kinetics of silver and fluoride after topical application of SDF.Methods
Sixteen adults participated in a pharmacokinetics study after the application of 38% SDF to 5 teeth (approximately 50 microliters, estimated 4-11 milligrams per participant). Serum and urine samples were collected over 24 hours after application and were analyzed for silver and fluoride.Results
Silver serum peak was 0.67 (standard deviation [SD], 0.49) nanograms per milliliter; median time to peak was 3 hours. The estimated elimination half-life of silver was 46 (SD, 26) hours. No silver was recovered in urine. Baseline fluoride serum levels ranged from less than 10 through 50 ng/mL (< 0.01-0.05 parts per million) and fluctuated around baseline after SDF. The 24-hour urinary fluoride was 1.29 (SD, 0.81) mg.Conclusions
SDF was well tolerated in this study, and no adverse events related to SDF were reported.Practical Implications
This clinical study confirmed that topical application of 38% SDF, in growing use in the United States, is safe and well tolerated in healthy adults. 相似文献2.

Background
There is a large variation among clinicians when managing deep carious lesions (DCLs). The purpose of this study was to assess general dentists’ (GDs), pediatric dentists’ (PDs), and endodontists’ (EDs) diagnostic methods, clinical decision-making considerations, treatment strategies, and knowledge, behavior, and attitudes related to the diagnosis and treatment of DCLs.Methods
A total of 175 GDs, 511 PDs, and 377 EDs responded to a nationwide Web-based survey.Results
Most EDs (68%) and GDs (47%) practiced complete caries removal. PDs (31%) were more likely than GDs (12%) and EDs (4%) to remove carious tissues partially. Dentin hardness was the most important diagnostic criterion used during caries excavation (GDs, 90%; PDs, 72%; EDs, 88%). Only 30% of GDs, 17% of PDs, and 90% of EDs used diagnostic tests (for example, a cold test) when assessing pupal health. A substantial percentage of respondents considered endodontic treatment as a choice for treating DCLs in asymptomatic teeth in young patients (GDs, 40%; PDs, 30%; EDs, 40%). GDs rarely used a rubber dam when treating these lesions.Conclusions
Most respondents practiced complete caries removal until hard dentin was felt, using hardness as the primary excavation criterion, and did not use pulp diagnostic tests routinely before making decisions about treatment of teeth with DCLs.Practical Implications
Efforts should be made to translate the growing body of evidence supporting the use of conservative caries removal criteria to preserve pulpal health and tooth structure integrity when managing DCLs. 相似文献3.

Background
Except for a small increase in caries prevalence in young children from 1999 through 2004, the prevalence of pediatric caries in the United States has remained consistent for the past 3 decades.Methods
The authors used data from the National Health and Nutrition Examination Survey (NHANES) (from 1999 through 2004 and from 2011 through 2014) to ascertain changes in caries prevalence in youth aged 2 to 19 years. The authors evaluated changes in the prevalence of caries experience, untreated caries, and severe caries (3 or more teeth with untreated caries) in the primary, mixed, and permanent dentition according to poverty status.Results
Untreated dental caries in the primary dentition decreased (24% versus 14%) for children aged 2 to 8 years regardless of poverty status from the period from 1999 through 2004 to the period from 2011 through 2014. Severe caries in primary teeth decreased between the period from 1999 through 2004 and the period from 2011 through 2014 for 2- to 8-year-olds (10% versus 6%). Among preschool-aged children in families with low incomes, caries experience decreased from nearly 42% to 35%, and untreated caries decreased from 31% to 18%. Furthermore, there were significant reductions in the number of carious dental surfaces and significant increases in the number of restored dental surfaces. Overall, there was little change in the prevalence of caries in older children and adolescents.Conclusions
The prevalence of caries in primary teeth in preschool-aged children has improved in the previous decade in the United States; however, the prevalence of having no caries experience in permanent teeth in children and adolescents remains unchanged.Practical Implications
Although the oral health status of young children has improved in the previous decade, few changes have occurred for many older children and adolescents. 相似文献4.

Background
The authors clarified the causal mechanisms underlying the high prevalence of dental disease encountered in people who habitually use methamphetamine (meth).Methods
Using a stratified sampling approach, the authors conducted comprehensive oral examinations and psychosocial assessments for 571 study participants who used meth. Three calibrated dentists, who used National Health and Nutrition Examination Survey (NHANES) protocols, characterized the study participants’ dental disease. The authors also collected data related to study participants’ history of meth use and other attributes linked to dental disease.Results
Study participants who used meth manifested higher rates of xerostomia and caries experience compared with NHANES control participants. Participants who used meth had a higher level of daily consumption of sugary beverages compared with NHANES control participants. Smoking meth did not increase caries experience over other modes of intake. Dental hygiene was a significant determinant of dental health outcomes.Conclusions
Mode of intake and frequency of meth use have a minimal impact on dental health outcomes. Behaviors, such as sugary beverage consumption and poor oral hygiene, better explain dental health outcomes.Practical Implications
Having a better understanding of the causal mechanisms of “meth mouth” sets the stage for clinicians to provide more personalized interventions and management of dental disease in people who use meth. 相似文献5.

Background
Clinicians often use calcium hydroxide liners during stepwise treatment of advanced caries. In this randomized clinical trial, the authors compared the short-term outcome of stepwise caries removal with and without use of a calcium hydroxide liner in conjunction with provisional resin-modified glass ionomer (RMGI) restorations.Methods
The authors included in the trial 98 patients aged 15 to 30 years who had a deep carious lesion in a posterior tooth. The authors measured the dentin thickness radiographically and recorded its color, consistency, and moisture, as well as the bacterial count of the lesions. After partial caries removal, the authors assigned patients randomly to have their caries provisionally restored using RMGI with (control group) or without (test group) a calcium hydroxide liner. The primary outcome measure was tooth vitality after 90 days. Secondary outcomes included changes in dentinal, radiographic, and microbiological characteristics of the lesions.Results
The authors found no statistically significant difference between the test and control groups in tooth vitality after 90 days. Irrespective of calcium hydroxide liner use, the authors observed darker, harder, drier, and less contaminated dentin after the provisional restorations, but dentin thickness remained unchanged.Conclusions
On the basis of this 3-month clinical trial’s results, the use of a calcium hydroxide liner during stepwise caries excavation and provisional restoration did not provide any additional benefit.Practical Implications
After 3 months, using a calcium hydroxide liner does not appear to offer any additional benefit when clinicians use RMGI provisional restorations during stepwise caries removal. Longer studies are needed to confirm these results. 相似文献6.

Background
Sugar-sweetened beverages (SSBs) are dietary sources of sugar that are factors in caries development and tooth loss. Dietary sugar also is linked to diabetes mellitus (DM). There is limited research related to SSBs and tooth loss in people with DM. The authors investigated the association between SSBs and tooth loss as it related to the presence or absence of DM.Methods
The authors used a cross-sectional design with data reported by adults (18 years and older) who responded to the 2012 Behavior Risk Factor Surveillance System questionnaire, which was used in 18 states (N = 95,897; 14,043 who had DM and 81,854 who did not have DM). The authors conducted χ2 and logistic regression analyses to determine associations related to DM status.Results
Overall, 12.3% of the survey respondents had DM, 15.5% had 6 or more teeth extracted, and 22.6% reported that they consumed 1 or more SSB daily. In the adjusted analyses, among adults who had DM, those who consumed at least 2 SSBs daily were more likely to have had 6 or more teeth extracted than those who reported that they did not consume SSBs (adjusted odds ratio, 2.35; 95% confidence interval, 1.37 to 4.01; P = .0018). Among adults who did not have DM, those who consumed more than 1 but fewer than 2 SSBs per day were more likely to have had at least 6 teeth extracted (adjusted odds ratio, 1.46; 95% confidence interval, 1.21 to 1.77; P < .0001).Conclusions
The authors found that, among adults with DM, consuming 2 or more SSBs per day was associated with having had 6 or more teeth extracted.Practical Implications
Dietary sugar is a concern for oral and systemic health; however, a strong, independent relationship between the number of teeth extracted and a single source of dietary sugar is not adequate to explain the complexity of tooth loss. Clinicians should use broadly worded dietary messages when discussing caries assessment with patients. 相似文献9.

Background
The authors conducted a retrospective study to evaluate the long-term (18-22 years) clinic results of titanium post and bonded amalgam core restorations with metal-ceramic crowns placed in patients.Methods
From 1992 through 1996, the authors placed 88 restorations in 66 patients. They measured the ferrule effect in the minor dentin collar area. In 2014, the authors analyzed the following variables: ferrule length, length and thickness of the post, and tooth position.Results
The overall survival of the restorations decreased over time with survival rates of 89.6% after 5 years of follow-up appointments and 64.2% after 18 years of follow-up appointments. There were 42 failures, and the maxillary premolars had the most failures. The teeth with 2 or more millimeters ferrule length had a higher survival rate than those with a 0 to less than 2 mm ferrule length; these results were not statistically significant.Conclusions
Statistically significant differences were detected according to the location of the tooth. The cores in the anterior teeth were 3.26 times more likely to fail than those in the molars, which presented higher survival rates; maxillary premolars had the most failures (28.5%). Both the metallic post length and its diameter did not influence restoration survival. The ferrule length was not statistically significant.Practical Implications
The clinical technique to restore endodontically treated teeth that includes a titanium post and bonded amalgam restorations results in greater coronal destruction but shows good long-term results, ease of fabrication, and modest cost in comparison with other techniques. 相似文献10.

Background
No evidence-based guidelines exist for preventive dental care before radiation therapy (RT) in patients with head and neck cancer (HNC). An ongoing multicenter, prospective cohort study, Clinical Registry of Dental Outcomes in Head and Neck Cancer Patients (OraRad), is addressing this knowledge gap. The authors evaluated the level of dental disease before RT in the OraRad cohort, factors associated with dental disease, and dental treatment recommendations made before RT.Methods
As part of OraRad, the authors assessed caries, periodontal disease, dental recommendations, and dental interventions performed before RT.Results
Baseline measures were reported for 356 participants (77% men) with mean (standard deviation) age of 59.9 (11.0) years. Measures included mean number of teeth (22.9), participants with at least 1 tooth with caries (37.2%), and participants with at least 1 tooth with probing depth 5 millimeters or greater (47.4%). Factors associated with less extensive dental disease before RT included having at least a high school diploma, having dental insurance, history of routine dental care, and a smaller tumor size (T1 or T2). Based on the dental examination before RT, 163 (49.5%) participants had dental treatment recommended before RT, with extractions recommended most frequently.Conclusion
Many patients with HNC require dental treatment before RT; more than one-third require extractions.Practical Implications
Most patients have some level of dental disease at the start of RT, indicating the importance of dental evaluation before RT. By observing dental outcomes after RT, OraRad has the potential to determine the best dental treatment recommendations for patients with HNC. 相似文献11.

Background
The effectiveness of stainless steel crowns (SSCs) versus direct restorations when placed in primary mandibular molars (teeth nos. L and S) is uncertain. The authors evaluated effectiveness by gauging longevity of treatment.Methods
The authors obtained private dental insurance claims (2004-2016) from a national dental data warehouse. Paid insurance claims records (n = 1,323,489) included type of treating dentist, treatment placed, and patient age.Results
Dentist specialty, type of treatment, and patient age were significant in predicting failure after the first restoration. The authors found high survival rates for all treatments (> 90%) after 5 years; however, as soon as within 3 years after treatment, SCCs had approximately 6% better survival.Conclusions
Teeth nos. L and S first treated with SSCs lasted longer without new treatment compared with teeth first treated with direct restorations; the difference was small. Teeth treated by pediatric dentists had better survival rates.Practical Implications
Primary mandibular first molars initially treated with SSCs lasted longer without new treatment compared with direct restorations. Overall dental care costs of the former were considerably higher. 相似文献12.

Background
Awake bruxism is a common clinical condition that often goes undetected, often leading to pain or damaged teeth and restorations.Methods
The authors searched electronic databases regarding the treatment and effects of awake bruxism compared with those of sleep bruxism. The authors used the search terms diurnal bruxism and oral parafunction. The authors combined information from relevant literature with clinical experience to establish a recommended protocol for diagnosis and treatment.Results
The authors found articles regarding the diagnosis and treatment of bruxism. The authors combined information from the articles with a review of clinical cases to establish a treatment protocol for awake bruxism.Conclusions
Literature and clinical experience indicate a lack of patient awareness and, thus, underreporting of awake bruxism. As a result, myriad dental consequences can occur from bruxism. The authors propose a need for increased awareness, for both patients and professionals, particularly of the number of conditions related to awake bruxism.Practical Implications
Clinicians should look for clinical signs and symptoms of awake bruxism and use minimally invasive treatment modalities. 相似文献13.

Background
The authors explored the relationship between income inequality and self-reported oral health and oral health–related quality of life.Methods
The authors used an online survey to gather data about US adults’ perceptions of their overall oral health and how oral health affected their quality of life. The authors categorized respondents as coming from areas of low, medium, or high income inequality on the basis of a county-level Gini coefficient.Results
Results of χ2 tests and an analysis of variance indicated that there was a significant association between income inequality and oral health as measured by using the overall condition of the mouth and teeth, life satisfaction, and frequency of experiencing functional and social problems related to oral health. Generally, adults from areas of lower income inequality reported better oral health and oral health–related quality of life.Conclusions
Income inequality has the potential to affect both functional and social dimensions of oral health, possibly through a psychosocial pathway. Future research is necessary to determine whether any causal link exists.Practical Implications
Our findings may inform oral health policy. Long-term policies designed to improve the oral health of Americans could work best when supported by policies designed to reduce levels of income inequality, and thereby, may reduce oral health inequalities. Further research is needed to examine the effectiveness of such policies. 相似文献14.

Background
The authors systematically reviewed the scientific evidence regarding an association between oral health literacy (OHL) and oral conditions.Types of Studies Reviewed
The authors performed an electronic search of 8 databases up through October 2016, as well as a manual search. The authors included studies in which the investigators evaluated oral conditions and measured OHL through a validated tool and studies in which OHL was an explanatory variable. The authors assessed risk of bias by using the Newcastle-Ottawa Scale.Results
The authors included 10 cross-sectional studies. Risk of bias was high in most studies (n = 6). Dental caries and periodontal status were the most common oral conditions reported (each outcome was reported in 5 studies). Investigators in 4 studies found a statistically significant association between dental caries and lower levels of OHL (P < .05), with investigators in 3 of the studies finding this in primary teeth. A reduced number of teeth and loss of attachment were associated with lower levels of OHL (P < .05). Findings for deep periodontal pockets, bleeding on probing, severity of periodontal disease, history of extractions, dental treatment need, and dental plaque were inconclusive. Investigators barely reported other clinical conditions such as temporomandibular joint problems, oral mucosal lesions, enamel opacities, dental fluorosis, and use of and need for dental prostheses.Conclusions and Practical Implications
There seems to be a weak association between lower levels of OHL and dental caries in primary teeth. Similar findings for adults and between OHL and other oral conditions remain unsubstantiated because the results are controversial, with considerable clinical and statistical heterogeneity between studies. 相似文献15.

Background
Few researchers have investigated the relationship between supernumerary teeth (ST) and impacted incisors. The authors investigated the relationship between ST and impacted incisors in the maxillary anterior area in the mixed dentition.Methods
Using cone-beam computed tomography, the authors diagnosed 417 ST among 294 patients (age range, 6-12 years; 220 boys and 74 girls). The number, morphology, growth orientation, and position of ST were recorded along with the presence of impacted incisors.Results
The authors reported that 23.1% of patients having ST (n = 68; mean [standard deviation] age 8.5 [1.6] years) also had impacted incisors. Morphology (molariform and odontomelike), growth orientation (normal and no orientation), and position (coronal) of the ST were significantly associated with impacted incisors (P < .05 for all). An increase of 1 year in age was associated with a decreased risk of having ST accompanied by impacted incisors (odds ratio, 0.76; 95% confidence interval, 0.63 to 0.92). An increase of 1 ST more than doubled the risk of having an impacted incisor (odds ratio, 2.39; 95% confidence interval, 1.44 to 3.96).Conclusions
In this population, the number, morphology, growth orientation, and position of ST as well as the patient’s age were associated with impacted incisors in the maxillary anterior area during the mixed dentition.Practical Implications
The presence and morphology of ST should alert the clinician to the increased likelihood of having impacted incisors and the need for early diagnosis and appropriate treatment. 相似文献16.

Introduction
The purpose of this study was to compare different high-resolution cone-beam computed tomographic (CBCT) imaging protocols in the diagnosis of incomplete root fractures of endodontically treated teeth.Methods
Twenty single-rooted human teeth were endodontically treated, and an incomplete root fracture was induced. The teeth were scanned with the CBCT unit PreXion 3D (Teracom, San Mateo, CA) operating at 2 different protocols: high resolution/standard (HI-STD) (19 seconds and 512 basis images) and high resolution/high density (HI-HI) (37 seconds and 1024 basis images). Three oral radiologists evaluated all images using multiplanar reconstructions. The diagnostic tests and the receiver operating characteristic (ROC) curve were calculated.Results
The HI-STD and HI-HI protocols presented an accuracy of 0.90 and 0.93, respectively, and both protocols had a sensitivity of 0.97. The HI-HI protocol showed a higher positive predictive value and slightly higher areas under the ROC curve.Conclusions
Both high-resolution imaging protocols presented high accuracy in the detection of incomplete root fracture of endodontically teeth. Thus, the HI-STD protocol should be indicated this reduces the radiation dose. 相似文献18.

Statement of problem
Conventional diagnostic aids based upon imagery and patient symptoms do not indicate whether restorative treatments have eliminated structural pathology.Purpose
The purpose of this clinical study was to evaluate quantitative percussion diagnostics (QPD), a mechanics-based methodology that tests the structural integrity of teeth noninvasively. The study hypothesis was that QPD would provide knowledge of the structural instability of teeth after restorative work.Material and methods
Eight participants with 60 sites needing restoration were enrolled in an IRB-approved clinical study. Each participant was examined comprehensively, including QPD testing. Each site was disassembled and microscopically video documented, and the results were recorded on a defect assessment sheet. A predictive model was developed for the pathology rating based on normalized fit error (NFE) values using data from the before treatment phase of the study published previously. Each restored site was then tested using QPD. The mean change in NFE values after restoration was evaluated by the pathology rating before treatment. The model was then used to predictively classify the rating after restoration based on the NFE values after treatment. The diagnostic potential of the rating was explored as a marker for risk of pathology after restoration.Results
After restoration, 51 of the 60 sites fell below an NFE of 0.04, representing a greatly stabilized tooth site sample group. Several sites remained in the high-risk category and some increased in pathologic micromovement. Two models were used to determine severity with indicative cutoff points to group sites with similar values.Conclusions
The data support the hypothesis that QPD can indicate a revised level of structural instability of teeth after restoration. 相似文献19.

Background
Sales of charcoal dentifrices and powders have rapidly emerged into the Internet marketplace. The authors conducted a literature review to examine the efficacy and safety of charcoal and charcoal-based dentifrices.Methods
The authors searched the MEDLINE and Scopus databases for clinical studies on the use of charcoal and charcoal-based dentifrices and laboratory investigations on the bioactivity or toxicity of charcoal and charcoal-based dentifrices, published through February 2017. The authors used a defined search strategy to identify randomized, controlled clinical trials with a follow-up duration of 3 months or longer. In addition, the authors selected the first 50 consecutive charcoal dentifrices from Google.com and Amazon.com for ascertainment of product assortment and advertising promotions.Results
The authors’ literature search identified 118 potentially eligible articles. Thirteen studies reported brushing the teeth with raw charcoal or soot; however, none of these studies met the inclusion criteria. Two studies offered nonspecific caries reductions, 3 studies reported deleterious outcomes (increased caries, enamel abrasion, nonquantified negative impact), and 1 study indicated only that brushing with raw charcoal had no adverse effects on oral hygiene. Seven other studies reported only on the use of charcoal for oral hygiene. Internet advertisements included unsubstantiated therapeutic claims—such as antibacterial, antifungal, antiviral, and oral detoxification, as well as potentially misleading product assertions. One-third of the charcoal dentifrices contained bentonite clay, and 1 contained betel leaves.Conclusions
The results of this literature review showed insufficient clinical and laboratory data to substantiate the safety and efficacy claims of charcoal and charcoal-based dentifrices. Larger-scale and well-designed studies are needed to establish conclusive evidence.Practical Implications
Dental clinicians should advise their patients to be cautious when using charcoal and charcoal-based dentifrices with unproven claims of efficacy and safety. 相似文献20.
