Abstract
PURPOSE Case-based simulations are powerful training tools that can enhance learning and drive behavior change. This is an overview of the design/development of Dental Decision Simulation (DDSim), a web-based simulation of an electronic dental record (EDR). The purpose was to use DDSim to train dentists to make evidence-based treatment planning decisions consistent with current evidence. This simulated EDR provides case-based information in support of a set of defined evidence-based learning objectives. METHODS The development of this complex simulation model required coordinated efforts to create several components: identify behavior changes, case authoring mechanism, create virtual patient visits, require users to make treatment plan decisions related to learning objectives, and a feedback mechanism to help users recognize departures from those learning objectives. This simulation was evaluated in a 2-arm, clinic-randomized, controlled pilot study examining the extent to which DDSim changed dentists' planned treatment to conform to evidence-based treatment guidelines relative to change in dentists not exposed to DDSim. Outcomes were measured by comparing preintervention and postintervention patient EDR treatment data. RESULTS Changes in behavior over time did not favor intervention or control clinics. CONCLUSION DDSim provides a standardized learning platform that cannot be achieved through the use of live patients. Both live patients and case-based simulations can be used to transfer knowledge and skill development. DDSim offers the advantage of providing a platform for developing treatment planning skills in a low-risk environment. However, further research examining behavior change is needed.

Abstract
BACKGROUND A suspicious occlusal carious lesion (SOCL) can be defined as a lesion with no cavitation and no radiographic radiolucency but for which caries is suspected. The authors evaluated whether using a device changed the percentage of SOCLs that were opened surgically and, among those SOCLs that were opened, the proportion that had penetrated into dentin. METHODS Eighty-two dentists participated. In phase 1 of the study, dentists identified approximately 20 SOCLs, obtained patient consent, and recorded information about the lesion, treatment or treatments, and depth, if opened. Dentists were then randomly assigned into 1 of 3 groups: no device, DIAGNOdent (KaVo), and Spectra (Air Techniques). In phase 2, dentists enrolled approximately 20 additional patients and recorded the same phase 1 information while using the assigned device to help make their treatment decisions. A mixed-model logistic regression was used to determine any differences after randomization in the proportion of lesions opened and, if opened, the proportion of lesions that penetrated into dentin. RESULTS A total of 1,500 SOCLs were enrolled in each phase. No statistically significant difference was found in the change in proportion of lesions receiving invasive treatment from phase 1 to phase 2 across the 3 groups (P = .33) or in the change in proportion of percentage of opened lesions that extended into dentin (P = .31). CONCLUSION Caries-detecting devices in the study did not change substantially dentists' decisions to intervene or the accuracy of the intervention decision in predicting lesion penetration into dentin. PRACTICAL IMPLICATIONS The caries-detecting devices tested may not improve dentists' clinical decision making for SOCLs.

Abstract
OBJECTIVE Case presentations (vignettes) were completed by dentists in the National Dental Practice-Based Research Network study "Decision Aids for the Management of Suspicious Occlusal Caries Lesions (SOCLs)". The objective was to determine dentists' decision strategies for SOCLs. METHODS 107 dentists viewed a series of 16 vignettes that represented all combinations of 4 clinical cues: color, luster, lesion roughness, and patient-level caries risk. Each vignette included a patient description and a photograph of a tooth presenting the 4 cues. Dentists were asked to decide the likelihood that a suspected lesion extended into dentin. A lens model analysis was used to examine how dentists use these cues in making their decisions. RESULTS 86% of dentists had a consistent pattern of cue use that defined their decision strategy. On average, 70% of the variance in their decisions was accounted for by their use of the 4 cues. However, there was considerable variability in the individual cues used by each dentist. The percentages of dentists who used the different cues consistently were: luster (58%), color (48%), roughness (36%), and risk (35%). 14% of dentists reliably used only color, 7% used only luster, 4% used only roughness, and 1% used only risk when making SOCL decisions. CONCLUSIONS The online vignette system suggests that clinical SOCL decision strategies are highly individualized and dentists do not use all cues available to them to make these decisions. CLINICAL SIGNIFICANCE Prior to this study, there has been little evidence about how dentists use these cues (either individually or in combination) when judging the extent of caries progression. Such knowledge would be valuable when designing interventions to help dentists maximize the likelihood of appropriate treatment decisions.

Abstract
OBJECTIVE A systematic review was conducted to address this clinical question: Does consumption of (non-dairy) sugar-containing beverages (SCBs) among children under age 12 result in excess weight gain? METHODS The authors searched four databases for controlled trials (randomized and non-randomized) and cohort studies published in English through March 29, 2016: PubMed, EMBASE, Cochrane Database of Systematic Reviews, CINAHL. Initial and full-text screening, data abstraction, and risk of bias assessment were performed independently and in duplicate. RESULTS Thirty-eight studies met inclusion criteria for this systematic review. One was a randomized controlled trial, and 37 were cohort studies. Though the results of these studies were mixed, the majority demonstrated a statistically significant positive association between SCB consumption in children under age 12 and total adiposity and central adiposity. In contrast, most studies that assessed 100 percent fruit juice consumption only with either total adiposity or central adiposity did not support an association. Among only children under age 5 at baseline, no studies examined central adiposity, but nearly all studies examining SCBs and total adiposity, and a majority examining only fruit juice consumption, demonstrated a statistically significant positive association. CONCLUSION Our results support a statistically significant positive association between SCBs and total and central adiposity among children under age 12. This association is most consistent for total adiposity among children <5. Our results for 100 percent fruit juice only suggest differences by age, as most studies among those < 12 were negative but most among those <5 were positive.

Abstract
This study aimed to find the set of risk indicators best able to predict root caries (RC) incidence in caries-active adults utilizing data from the Xylitol for Adult Caries Trial (X-ACT). Five logistic regression models were compared with respect to their predictive performance for incident RC using data from placebo-control participants with exposed root surfaces at baseline and from two study centers with ancillary data collection (n = 155). Prediction performance was assessed from baseline variables and after including ancillary variables [smoking, diet, use of removable partial dentures (RPD), toothbrush use, income, education, and dental insurance]. A sensitivity analysis added treatment to the models for both the control and treatment participants (n = 301) to predict RC for the control participants. Forty-nine percent of the control participants had incident RC. The model including the number of follow-up years at risk, the number of root surfaces at risk, RC index, gender, race, age, and smoking resulted in the best prediction performance, having the highest AUC and lowest Brier score. The sensitivity analysis supported the primary analysis and gave slightly better performance summary measures. The set of risk indicators best able to predict RC incidence included an increased number of root surfaces at risk and increased RC index at baseline, followed by white race and nonsmoking, which were strong nonsignificant predictors. Gender, age, and increased number of follow-up years at risk, while included in the model, were also not statistically significant. The inclusion of health, diet, RPD use, toothbrush use, income, education, and dental insurance variables did not improve the prediction performance.

Abstract
OBJECTIVE To describe the full range of behavior of the visible, noncavitated, early caries lesion in caries-active adults with substantial fluoride exposure, and to consider implications. METHODS The data were from the Xylitol for Adult Caries Trial (X-ACT) collected annually for 33 months using condensed ICDAS caries threshold criteria. Individual tooth surfaces having a noncavitated caries lesion were included, and the patterns of transition to each subsequent annual clinical examination to sound, noncavitated or cavitated, filled or crowned were determined. The resulting sets of patterns for an individual tooth surface, looking forward from its first appearance as a noncavitated lesion, were combined into one of four behavior profiles classified as reversing, stable, oscillating, or continuously progressing, or were excluded if not part of the caries continuum. The distributions of profile types were assessed using the Rao-Scott chi-square test, which adjusts for clustering of tooth surfaces within teeth. RESULTS Inter- and intra-examiner kappa scores demonstrated acceptable calibration at baseline and annually. 8084 tooth surfaces from 543 subjects were included. The distribution of profile types differed significantly between coronal and root surfaces. Overall, two-thirds of all coronal noncavitated lesions were first seen at baseline, half reversed, over a fifth were stable, 15% oscillated, and only 8.3% progressed to cavitation, filled, or crowned in 33 months or less (6.3% consistently Progressed plus 2.0% inconsistently, a subset of oscillating, which oscillated before progressing to cavitation). Approximal, smooth, and occlusal coronal surfaces each were significantly different in their individual distributions of profile types. Xylitol showed no significant and consistent effect on this distribution by tooth surface type. This was in keeping with the X-ACT's lack of effect of xylitol at the noncavitated plus cavitated lesion thresholds combined. CONCLUSIONS This study demonstrated the full dynamic range of early caries lesion behavior. The great majority were not progressive, and few (8.3%) became cavitated over 33 months in caries-active adults using fluorides. Important caries management implications favoring recorded longitudinal monitoring, prevention of active risks, and minimal restoration only after direct visual determination of cavitation are discussed.

Abstract
OBJECTIVE To (1) quantify the diagnostic techniques used by Dental Practice-Based Research Network (DPBRN) dentists before they decide to treat primary caries lesions surgically and (2) examine whether certain dentist, practice, and patient characteristics are associated with their use. METHODS A total of 228 DPBRN dentists recorded information on 5,676 consecutive restorations inserted due to primary caries lesions on 3,751 patients. Practitioner-investigators placed a mean of 24.9 (SD = 12.4) restorations. Lesions were categorized as posterior proximal, anterior proximal, posterior occiusal, posterior smooth, or anterior smooth. Techniques used to diagnose the lesion were categorized as clinical assessment, radiographs, and/or optical. Statistical analysis utilized generalized mixed-model ANOVA to account for the hierarchical structure of the data. RESULTS By lesion category, the diagnostic technique combinations used most frequently were clinical assessment plus radiographs for posterior proximal (47%), clinical assessment for anterior proximal (51%), clinical assessment for posterior occlusal (46%), clinical assessment for posterior smooth (77%), and clinical assessment for anterior smooth (80%). Diagnostic technique was significantly associated with lesion category after adjusting for clustering in dentists (p < 0.0001). CONCLUSION These results--obtained during actual clinical procedures rather than from questionnaire-based hypothetical scenarios--quantified the diagnostic techniques most commonly used during the actual delivery of routine restorative care. Diagnostic technique varied by lesion category and with certain practice and patient characteristics.

Abstract
Questionable occlusal carious lesions (QOC) can be defined as an occlusal tooth surface with no cavitation and no radiographic radiolucencies, but caries is suspected due to roughness, surface opacities or staining. An earlier analysis of data from this study indicates 1/3 of patients have a QOC. The objective of this report has been to quantify the characteristics of these common lesions, the diagnostic aids used and the treatment of QOC. A total of 82 dentist and hygienist practitioner-investigators from the USA and Denmark in the National Dental Practice-Based Research Network participated. When consenting patients presented with a QOC, information was recorded about the patient, tooth, lesion and treatments. A total of 2,603 QOC from 1,732 patients were analyzed. The lesions were usually associated with a fissure, on molars, and varied from yellow to black in color. Half presented with a chalky luster and had a rough surface when examined with an explorer. There was an association between color and luster: 10% were chalky-light, 47% were shiny-dark and 42% were mixtures. A higher proportion of chalky than of shiny lesions were light (22 vs. 9%; p < 0.001). Lesions light in color were less common in adults than in pediatric patients (9 vs. 32%; p < 0.001). Lesions that were chalky and light were more common among pediatric than among adult patients (22 vs. 6%; p < 0.001). This is the first study to investigate characteristics of QOC in routine clinical practice. Clinicians commonly face this diagnostic uncertainty. Determining the characteristics of these lesions is relevant when making diagnostic and treatment decisions.

Abstract
BACKGROUND Documenting the gap between what is occurring in clinical practice and what published research findings suggest should be happening is an important step toward improving care. The authors conducted a study to quantify the concordance between clinical practice and published evidence across preventive, diagnostic and treatment procedures among a sample of dentists in The National Dental Practice-Based Research Network ("the network"). METHODS Network dentists completed one questionnaire about their demographic characteristics and another about how they treat patients across 12 scenarios/clinical practice behaviors. The authors coded responses to each scenario/clinical practice behavior as consistent ("1") or inconsistent ("0") with published evidence, summed the coded responses and divided the sum by the number of total responses to create an overall concordance score. The overall concordance score was calculated as the mean percentage of responses that were consistent with published evidence. RESULTS The authors limited analyses to participants in the United States (N = 591). The study results show a mean concordance at the practitioner level of 62 percent (SD = 18 percent); procedure-specific concordance ranged from 8 to 100 percent. Affiliation with a large group practice, being a female practitioner and having received a dental degree before 1990 were independently associated with high concordance (≥ 75 percent). CONCLUSION Dentists reported a medium-range concordance between practice and published evidence. PRACTICAL IMPLICATIONS Efforts to bring research findings into routine practice are needed.

Abstract
OBJECTIVES To better understand the effectiveness of xylitol in caries prevention in adults and to attempt improved clinical trial efficiency. METHODS As part of the Xylitol for Adult Caries Trial (X-ACT), non cavitated and cavitated caries lesions were assessed in subjects who were experiencing the disease. The trial was a test of the effectiveness of 5 g/day of xylitol, consumed by dissolving in the mouth five 1 g lozenges spaced across each day, compared with a sucralose placebo. For this analysis, seeking trial efficiency, 538 subjects aged 21-80, with complete data for four dental examinations, were selected from the 691 randomized into the 3-year trial, conducted at three sites. Acceptable inter- and intra-examiner reliability before and during the trial was quantified using the kappa statistic. RESULTS The mean annualized noncavitated plus cavitated lesion transition scores in coronal and root surfaces, from sound to carious favoured xylitol over placebo, during the three cumulative periods of 12, 24, and 33 months, but these clinically and statistically nonsignificant differences declined in magnitude over time. Restricting the present assessment to those subjects with a higher baseline lifetime caries experience showed possible but inconsistent benefit. CONCLUSIONS There was no clear and clinically relevant preventive effect of xylitol on caries in adults with adequate fluoride exposure when non cavitated plus cavitated lesions were assessed. This conformed to the X-ACT trial result assessing cavitated lesions. Including non cavitated lesion assessment in this full-scale, placebo-controlled, multisite, randomized, double-blinded clinical trial in adults experiencing dental caries did not achieve added trial efficiency or demonstrate practical benefit of xylitol.

Abstract
OBJECTIVES The study aims to determine a) the extent of agreement between visual-tactile caries examination (VTE) and radiographic examination (RE) in detecting presumptive caries lesions on occlusal and proximal surfaces of posterior teeth of UNC Xylitol for Adult Caries Trial participants; and b) the additional caries diagnostic yield obtained by adding RE to VTE. METHODS Data consisted of surface-level visual-tactile and radiographic classification of disease (cavitated and noncavitated caries lesions) or nondisease (sound surfaces). Participants (n = 114, adults with ≥12 erupted teeth and 1-10 caries lesions) received baseline VTE by a trained and calibrated examiner, and had interproximal radiographs obtained within 7 months before or after the VTE. Radiographs were assessed independently by two trained and calibrated examiners masked with respect to VTE results. The diagnostic threshold was surface-level disease/nondisease status. Kappa statistics provided an estimate of VTE-RE agreement on diseased surfaces. The additional diagnostic yield of the RE over VTE was calculated as the additional lesions detected radiographically as a percentage of the total number of lesions detected by VTE. RESULTS Four-hundred ninety-four (51 occlusal, 433 proximal) lesions were detected; of these, 81 (2 occlusal, 79 proximal) lesions were detected by both VTE and RE. Kappa statistics were 0.18 (all surfaces), 0.04 (occlusal), and 0.18 (proximal). The additional diagnostic yield was 69 percent (all surfaces), 55 percent (occlusal), and 71 percent (proximal). CONCLUSIONS There is poor agreement between VTE and RE to detect caries in posterior teeth of caries-active adults. However, an RE performed within 7 months of a VTE adds caries diagnostic yield in a clinical trial, especially on proximal surfaces.

Abstract
The Xylitol for Adult Caries Trial was a three-year, double-blind, multi-center, randomized clinical trial that evaluated the effectiveness of xylitol vs. placebo lozenges in the prevention of dental caries in caries-active adults. The purpose of this secondary analysis was to investigate whether xylitol lozenges had a differential effect on cumulative caries increments on different tooth surfaces. Participants (ages 21-80 yrs) with at least one follow-up visit (n = 620) were examined at baseline, 12, 24, and 33 months. Negative binomial and zero-inflated negative binomial regression models were used to estimate incidence rate ratios (IRR) for xylitol's differential effect on cumulative caries increments on root and coronal surfaces and, among coronal surfaces, on smooth (buccal and lingual), occlusal, and proximal surfaces. Participants in the xylitol arm developed 40% fewer root caries lesions (0.23 D2FS/year) than those in the placebo arm (0.38 D2FS/year; IRR = 0.60; 95% CI [0.44, 0.81]; p < .001). There was no statistically significant difference between xylitol and control participants in the incidence of smooth-surface caries (p = .100), occlusal-surface caries (p = .408), or proximal-surface caries (p = .159). Among these caries-active adults, xylitol appears to have a caries-preventive effect on root surfaces (ClinicalTrials.gov NCT00393055).

Abstract
OBJECTIVE This paper uses baseline data from a randomized clinical trial to evaluate cross-sectional indicators of root caries in caries-active adults. MATERIALS AND METHODS Adults (21-80 years) having at least 12 erupted teeth and between one and ten caries lesions were enrolled. Participants (n = 437) received caries exams by trained, calibrated examiners and responded to baseline demographic and medical-dental questionnaires. We examined associations between baseline characteristics and (1) the presence of any root caries using Mantel-Haenszel hypothesis tests and odds ratio (OR) estimators and (2) the number of root surfaces with caries among study participants with exposed root surfaces (n = 349) using Mantel-Haenszel mean score tests and Mann-Whitney estimators. RESULTS/CONCLUSIONS Adjusting for study site and age, male gender [OR, 1.72; 95% confidence interval (CI), 1.08, 2.78], white race (OR, 2.39; 95% CI, 1.43, 3.98), recent dental visit (OR, 1.98; 95% CI, 1.07, 3.66), poor self-described oral health (OR, 2.65; 95% CI, 1.10, 6.39), and recent professional fluoride treatment (OR, 1.85; 95% CI, 1.06, 3.25) were significantly associated with increased odds to have any root caries, and study participants with exposed root surfaces characterized by male gender [Mann-Whitney probability estimate (MW) = 0.57; 95% CI, 0.51, 0.63), white race (MW, 0.61; 0.55, 0.68), recent dental visit (MW, 0.58; 0.50, 0.67), poor self-described oral health (MW, 0.61; 0.53, 0.69), and flossing at least once per day (MW, 0.57; 95% CI, 0.51, 0.62) were significantly more likely to have a greater number of root surfaces with caries than a randomly selected study participant from their respective complementary subgroups (female gender, non-white, etc.). CLINICAL RELEVANCE Our findings may help identify individuals at higher root caries risk.

Abstract
OBJECTIVES The performance of a recently developed survey instrument that inquires about patients' experiences with the receipt of dental care was examined to evaluate its potential utility as a patient-reported outcome measure for dental care plans. METHODS Individuals with dental insurance (n = 1,216) were surveyed using the Consumer Assessment of Health Care Providers and Systems (CAHPS) Dental Plan Survey. The instrument's pre-established composite and rating scores were compared across dental insurance carriers (6 most common and all others combined) using ANOVA. In addition, each score was analyzed separately using multivariate regression with respondent and plan characteristics as independent variables. RESULTS There was significant differentiation among dental insurance carriers for three of the six scores (dental care composite, access to care composite, and dentist rating). Several respondent characteristics were associated with higher scores, including age, race, income level, and oral health self-rating. Having a choice of dental plans, and years with one's dental plan were associated with higher dental plan ratings, while having to find a new dentist to use the plan tended to lower all scores except the cost and services composite. CONCLUSIONS The results reported here reflect differences among dental insurance carriers, rather than among the many different dental plans offered by those carriers. Nevertheless, the CAHPS instrument scores reflected differences among patients' experiences (composite scores) and ratings (rating scores) across carriers, suggesting both that the instrument should be a useful tool for assessing patient-reported outcomes, and that comparisons of these outcomes should control for respondent characteristics as well as specific plan characteristics.

Abstract
OBJECTIVES This report describes the training of dental examiners participating in two dental caries clinical trials and reports the inter- and intra-examiner reliability scores from the initial standardization sessions. METHODS Study examiners were trained to use a modified International Caries Detection and Assessment System II system to detect the visual signs of non-cavitated and cavitated dental caries in adult subjects. Dental caries was classified as no caries (S), non-cavitated caries (D1), enamel caries (D2), and dentine caries (D3). Three standardization sessions involving 60 subjects and 3,604 tooth surface calls were used to calculate several measures of examiner reliability. RESULTS The prevalence of dental caries observed in the standardization sessions ranged from 1.4 percent to 13.5 percent of the coronal tooth surfaces examined. Overall agreement between pairs of examiners ranged from 0.88 to 0.99. An intra-class coefficient threshold of 0.60 was surpassed for all but one examiner. Inter-examiner unweighted kappa values were low (0.23-0.35), but weighted kappas and the ratio of observed to maximum kappas were more encouraging (0.42-0.83). The highest kappa values occurred for the S/D1 versus D2/D3 two-level classification of dental caries, for which seven of the eight examiners achieved observed to maximum kappa values over 0.90. Intra-examiner reliability was notably higher than inter-examiner reliability for all measures and dental caries classifications employed. CONCLUSION The methods and results for the initial examiner training and standardization sessions for two large clinical trials are reported. Recommendations for others planning examiner training and standardization sessions are offered.

Abstract
OBJECTIVE To identify risk indicators that are associated with root caries incidence in published predictive risk models. METHODS Abstracts (n = 472) identified from a MEDLINE, EMBASE, and Cochrane registry search were screened independently by two investigators to exclude articles not in English (n = 39), published prior to 1970 (none), or containing no information on either root caries incidence, risk indicators, or risk models (n = 209). A full-article duplicate review of the remaining articles (n = 224) selected those reporting predictive risk models based on original/primary longitudinal root caries incidence studies. The quality of the included articles was assessed based both on selected criteria of methodological standards for observational studies and on the statistical quality of the modeling strategy. Data from these included studies were extracted and compiled into evidence tables, with information about the cohort location, incidence period, sample size, age of the study participants, risk indicators included in the model, root caries incidence, modeling strategy, significant risk indicators/predictors, and parameter estimates and statistical findings. RESULTS Thirteen articles were selected for data extraction. The overall quality of the included articles was poor to moderate. Root caries incidence ranged from 12% to 77% (mean ± SD = 45 ± 17%); follow-up time of the published studies was ≤ 10 years (range = 9; median = 3); sample size ranged from 23-723 (mean ± SD = 264 ± 203; median = 261); person-years ranged from 23 to 1540 (mean ± SD = 760 ± 556; median = 746). Variables most frequently tested and significantly associated with root caries incidence were (times tested; % significant; directionality): baseline root caries (12; 58%; positive); number of teeth (7; 71%; three times positive, twice negative), and plaque index (4; 100%; positive). Ninety-two other clinical and nonclinical variables were tested: 27 were tested three times or more and were significant between 9% and 100% of the times tested; and 65 were tested but never significant. CONCLUSIONS The root caries incidence indicators/predictors most frequently reported were root caries prevalence at baseline, number of teeth, and plaque index. This finding can guide targeted root caries prevention. There was substantial variation among published models of root caries risk in terms of variable selection, sample size, cohort location, assessment methods, incidence periods, association directionality, and analytical techniques. Future studies should emphasize variables frequently tested and often significant, and validate existing models in independent databases.

Abstract
As the number of dental-related randomized clinical trials (RCTs) increases, there is a need for literature to help investigators inexperienced in conducting RCTs design and implement studies. This commentary describes four "lessons learned" or considerations important in the planning and initial implementation of RCTs in dentistry that, to our knowledge, have not been discussed in the general dental literature describing trial techniques. These considerations are a) preparing or securing a thorough systematic review; b) developing a comprehensive set of study documents; c) designing and testing multiple recruitment strategies; and d) employing a run-in period prior to enrollment. Attention to these considerations in the planning phases of a dental RCT can help ensure that the trial is clinically relevant while also maximizing the likelihood that its implementation will be successful.

Abstract
BACKGROUND Dental caries is one of the primary causes of tooth loss among adults. It is estimated to affect a majority of Americans aged 55 and older, with a disproportionately higher burden in disadvantaged populations. Although a number of treatments are currently in use for caries prevention in adults, evidence for their efficacy and effectiveness is limited. METHODS/DESIGN The Prevention of Adult Caries Study (PACS) is a multicenter, placebo-controlled, double-blind, randomized clinical trial of the efficacy of a chlorhexidine (10% w/v) dental coating in preventing adult caries. Participants (n = 983) were recruited from four different dental delivery systems serving four diverse communities, including one American Indian population, and were randomized to receive either chlorhexidine or a placebo treatment. The primary outcome is the net caries increment (including non-cavitated lesions) from baseline to 13 months of follow-up. A cost-effectiveness analysis also will be considered. DISCUSSION This new dental treatment, if efficacious and approved for use by the Food and Drug Administration (FDA), would become a new in-office, anti-microbial agent for the prevention of adult caries in the United States. TRIAL REGISTRATION NUMBER NCT00357877.

Abstract
Background Dental caries incidence in adults is similar to that in children and adolescents, but few caries preventive agents have been evaluated for effectiveness in adults populations. In addition, dentists direct fewer preventive services to their adult patients. Xylitol, an over-the-counter sweetener, has shown some potential as a caries preventive agent, but the evidence for its effectiveness is not yet conclusive and is based largely on studies in child populations. Methods/Design X-ACT is a three-year, multi-center, placebo controlled, double-blind, randomized clinical trial that tests the effects of daily use of xylitol lozenges versus placebo lozenges on the prevention of adult caries. The trial has randomized 691 participants (ages 21-80) to the two arms. The primary outcome is the increment of cavitated lesions. Discussion This trial should help resolve the overall issue of the effectiveness of xylitol in preventing caries by contributing evidence with a low risk of bias. Just as importantly, the trial will provide much-needed information about the effectiveness of a promising caries prevention agent in adults. An effective xylitol-based caries prevention intervention would represent an easily disseminated method to extend caries prevention to individuals not receiving caries preventive treatment in the dental office.

Abstract
OBJECTIVE To (1) quantify the diagnostic techniques used by Dental Practice-Based Research Network (DPBRN) dentists before they decide to treat primary caries lesions surgically and (2) examine whether certain dentist, practice, and patient characteristics are associated with their use. METHODS A total of 228 DPBRN dentists recorded information on 5676 consecutive restorations inserted due to primary caries lesions on 3751 patients. Practitioner-investigators placed a mean of 24.9 (SD=12.4) restorations. Lesions were categorised as posterior proximal, anterior proximal, posterior occlusal, posterior smooth, or anterior smooth. Techniques used to diagnose the lesion were categorised as clinical assessment, radiographs, and/or optical. Statistical analysis utilised generalised mixed-model ANOVA to account for the hierarchical structure of the data. RESULTS By lesion category, the diagnostic technique combinations used most frequently were clinical assessment plus radiographs for posterior proximal (47%), clinical assessment for anterior proximal (51%), clinical assessment for posterior occlusal (46%), clinical assessment for posterior smooth (77%), and clinical assessment for anterior smooth (80%). Diagnostic technique was significantly associated with lesion category after adjusting for clustering in dentists (p<0.0001). CONCLUSION These results - obtained during actual clinical procedures rather than from questionnaire-based hypothetical scenarios - quantified the diagnostic techniques most commonly used during the actual delivery of routine restorative care. Diagnostic technique varied by lesion category and with certain practice and patient characteristics.

Abstract
This study investigated the concordance between pre- and postoperative assessments of primary caries lesion depths by dentists from The Dental Practice-Based Research Network (DPBRN; www.DentalPBRN.org). A total of 229 DPBRN dentists collected data on 8,351 consecutive restorations inserted due to primary caries in 5,810 patients. Dentists estimated the preoperative depth of caries lesions based on the diagnostic methods they typically used. The preoperative depth was then compared to the postoperative depth, which dentists determined using actual clinical observation. Both estimated and observed depths were recorded as being in the outer half (E1) or inner half (E2) of enamel, or in the outer third (D1), middle third (D2) or inner third (D3) of dentin. Most restorations were placed to treat lesions that were preoperatively assessed as extending to the D1 (53%) and D2 (25%) depths. Of the restored caries lesions, 10% were preoperatively assessed as being limited to E2 depth and 3% to E1 depth. The majority of the restored enamel lesions were located on occlusal surfaces. Preoperative estimates of caries lesion depth were more concordant with postoperative depths when the lesion was at an advanced stage: 88% concordance at the D3 depth, compared to 54% concordance at the E1 depth. DPBRN dentists can discriminate caries lesions at different depths, but the accuracy of their depth assessments was higher for dentin than for enamel lesions. In general, DPBRN dentists were more likely to underestimate than overestimate the depth of caries lesions, and the extent of underestimation was greater for enamel than for dentin lesions.

Abstract
OBJECTIVE This study evaluated the correlation between laser fluorescence readings and the extent of incipient occlusal caries as measured by the volume of tooth preparation in vitro. MATERIALS AND METHODS One hundred and three permanent molars and premolars containing incipient occlusal pit-and-fissure caries and sound occlusal surfaces (1/4 of the sample, control) were selected. DIAGNOdent (KaVo Dental Corporation, Lake Zurich, IL, USA) readings were obtained according to manufacturer instructions. Caries was removed with 1/4 round burs in high speed. The volume of tooth preparation was measured using a surrogate measure based on the amount of composite needed to fill the preparations. Sensitivity and specificity using different cutoff values were calculated for lesions/preparations extending into dentin. The results were analyzed statistically. RESULTS The Pearson correlation for preparation volume and DIAGNOdent reading measurements was low (r = 0.285). Sensitivity and specificity of DIAGNOdent for detection of dentinal lesions were 0.83 and 0.60, and 0.66 and 0.73 for the cutoff values of 20 and 30, respectively. CONCLUSIONS Within the limitations of this study, laser fluorescence measured with DIAGNOdent does not correlate well with extent of carious tooth structure in incipient occlusal caries. CLINICAL SIGNIFICANCE Clinicians should not rely only on DIAGNOdent readings to determine the extension of incipient occlusal caries.

Abstract
DATA SOURCES To find studies to include in the review, searches were made using Biomed Central, Cochrane Oral Health Reviews, Cochrane Library, the Directory of Open Access Journals, PubMed, Science Direct and the Research Findings Electronic Register. STUDY SELECTION English language clinical trials [randomised clinical trials (RCT) or quasi-RCT; in situ or in vivo] or systematic reviews (with or without meta-analysis) of published trials were selected that reported on the efficacy of phosphopeptide-amorphous calcium phosphate (CPP-ACP) using any mode of delivery. Studies were reviewed and their quality assessed independently. DATA EXTRACTION AND SYNTHESIS Data was extracted by two reviewers independently. Trials that were considered clinically and methodologically homogenous and that reported on similar outcomes were pooled for meta-analyses. RESULTS Twelve articles were included of which five in-situ RCT could be pooled for meta-analyses. The pooled in-situ results showed a weighted mean difference (WMD) of the percentage remineralisation scores in favour of chewing gum with 18.8 mg CPP-ACP, compared with chewing gum without CPP-ACP of -8.01 [95% confidence interval (CI), -10.54- -5.48; P 0.00001], and compared with no intervention of -13.56 (95% CI, -16.49- -10.62; P 0.00001). A significantly higher remineralisation effect was also observed after exposure to 10.0 mg CPP-ACP (WMD, -7.75; 95% CI, -9.84- -5.66; P 0.00001). One long-term in vivo RCT (24 months) with a large sample size (N = 2720) found that the odds of a tooth surface's progressing to caries was 18% less in subjects who chewed sugar-free gum containing 54 mg CPP-ACP than in control subjects who chewed gum without CPP-ACP (P 0.03). CONCLUSIONS Within the limitations of this systematic review with meta-analysis, the results of the clinical in-situ trials indicate a short-term remineralisation effect of CPP-ACP. Additionally, the promising in-vivo RCT results suggest a caries-preventing effect for long-term clinical CPP-ACP use. Further RCT are needed in order to confirm these initial results in vivo.

Abstract
OBJECTIVES This study aims to: (a) quantify the incidence of preventive dental services [in-office fluoride application and dental cleaning (prophylaxis)]; (b) determine if these services are effectively targeted to patients with the highest need; and (c) quantify the role of practice characteristics and patient-level factors in service receipt. METHODS A population-based prospective cohort study was conducted with 873 adults who had at least one tooth at baseline, 743 of whom provided 48-month data. In-person interviews and clinical examinations were conducted biennially for 48 months, with 6-monthly telephone interviews in between. Dental records were abstracted afterward, and practices that served participants completed questionnaires. Analysis was limited to persons with at least one dental visit of any type during follow-up (87 percent of the sample). RESULTS Only 9 percent of the persons received at least one fluoride application; 75 percent received a dental cleaning. Persons with high need were actually less likely to have received preventive services. In multivariable regression analyses, characteristics of the practice in which the subject received care were very strongly related to fluoride receipt, independent of patient-specific characteristics. CONCLUSIONS One preventive procedure was common; the other was uncommon. However, practices did not effectively target high-risk patients for either procedure. Instead, both services were typically received by persons with the least need for them. These findings are consistent with the conclusion that practitioners greatly influenced the delivery of fluoride services, with substantial contributions also made by patient-level predisposing and enabling factors for both preventive services.

Abstract
It generally is assumed by both dentists and patients that single crowns last a long time; however, the actual survival experience for crowns is not well-described and few comparisons have been reported in terms of survival for different types of crowns. A review of the literature reveals that while definitions of survival differ, the differences among crown types are relatively small, with all-ceramic posterior crowns demonstrating the poorest survival experience. Generally, 95% of crowns will remain in the mouth for at least five years--or, to use another definition of survival, more than 90% of crowns will not require catastrophic treatment within five years. Longer-term survival is less well-described; according to the literature, survival at 15-20 years ranges from 50-80%. These findings should help dentists and their patients to make informed treatment decisions regarding crowns.

Abstract
This article presents personal observations on how the concept of evidence-based dentistry is faring in the profession. It considers how the dental profession's concept of evidence has matured, how evidence-based dentistry was originally envisioned, how it is currently embodied, and what its prospects might be for the immediate future. Evidence-based dentistry began in the profession approximately 2 decades ago, initiated by the appearance of the first systematic reviews on dental topics in the late 1980s. The emergence of the concept of evidence-based dentistry--and its fundamental construct, the systematic review--marks what can be considered a fundamental shift in how the dental knowledge base has grown and developed over time.

Abstract
OBJECTIVE To assess the strength of the evidence describing the effectiveness of alternative strategies to the detection and management of early occlusal caries and suspected occlusal dentinal caries. METHODS Nine detection and intervention decision points were identified as being central to the management of early occlusal caries and suspected occlusal dentinal caries, or suspicious areas. For each decision point, the evidence for effectiveness was assessed, using existing systematic reviews when available, and nonsystematic review methods when necessary. RESULTS For the 2 detection decisions (early occlusal caries and suspicious areas) the strength of the evidence was weak. Accuracy in detecting early occlusal caries was extremely variable within and across detection methods. Approximately 50% of suspicious areas identified had dentinal caries. The strength of the evidence for effectiveness of nonsurgical approaches for the management of early occlusal caries was weak for all 3 management strategies examined (doing nothing, sealants, remineralization). This evidence suggested that sealants were highly effective, with remineralization reflecting moderate effectiveness. For the management of suspicious areas, the strength of the evidence was still weaker and reflected the same relative effectiveness. For the surgical management strategy for suspicious areas, operative treatment, the evidence was strong and reflected high effectiveness for preventive resin restorations, but no evidence was available for minimally invasive techniques. CONCLUSION Identification methods for early occlusal caries are not accurate. The strength of the evidence for effectiveness of nonsurgical management strategies for early occlusal caries is at best, weak. The available evidence suggests that sealing both enamel caries and suspected occlusal dentinal caries is the most effective management approach if subsequent maintenance of the sealed surfaces can be assured.

Abstract
OBJECTIVE To examine retrospectively the caries-related restorative experience of at-risk individuals who received fluoride-based preventive interventions to determine if the intervention resulted in fewer caries-related procedures. METHODS Administrative data from two dental health plans were used to determine the relationship between caries risk assessment (CRA) scores, preventive treatment and caries-related treatment procedures. We identified 45 693 adults who were consecutively enrolled for at least 1 year before and 2.5 years after the CRA. Variables representing the number of teeth with any caries-related treatment procedure and receipt of preventive treatment were created. RESULTS The outcome variable of interest was having at least one tooth with a caries-related procedure in the 2-year follow-up period. In plan A, the recommendation for home-use fluoride was not significantly related to caries-related treatment procedures in the follow-up period for individuals at low, moderate or high risk (P > 0.300). In plan B, application of in-office fluoride was associated with having at least one tooth with a caries-related treatment procedure in the follow-up period (P < 0.001). CONCLUSIONS We found incomplete compliance with guidelines for recommendation or administration of preventive treatment for patients at elevated risk for caries. We were also unable to identify any significant reductions in caries-related procedures for individuals receiving a fluoride intervention, compared with those who did not, when stratified by risk level.

Abstract
OBJECTIVE This study examined the predictive validity of a simple subjective method promoted to dentists for assessing their patients' caries risk. METHODS Data from two large group practices that have used guideline-assisted caries risk assessment (CRA) for several years were analyzed retrospectively to determine the receipt of caries-related treatment following a CRA. Patient age and receipt of caries preventive treatment subsequent to the CRA were control variables in logistic regressions to determine the likelihood of caries-related treatment for low, moderate, and high risk groups. RESULTS Among 45,693 individuals in the two plans, those categorized as being at high caries risk were approximately four times as likely to receive any caries-related treatment as those categorized as being at low caries risk. Those categorized as at moderate risk were approximately twice as likely to receive any treatment. In addition, for those at elevated risk who required any treatment, the number of teeth requiring treatment was larger. CONCLUSION The results of this study provide the first large-scale, generalizable evidence for the validity of dentists' subjective assessment of caries risk.

Abstract
BACKGROUND The DIAGNOdent, or DD (KaVo America, Lake Zurich, Ill.), a device for detecting caries using laser fluorescence, has been growing in popularity during the past three years. Although several evaluations of its diagnostic performance have appeared in the literature, the range of reported performances is extensive. TYPES OF STUDIES REVIEWED The authors conducted a systematic review of the literature to assess the diagnostic performance of the DD. Of 115 articles identified in the search, 25 studies were included in the review according to criteria requiring histologic validation and outcomes expressed as sensitivity and specificity values. RESULTS For detection of dentinal caries, sensitivity values ranged widely (0.19 to 1.0), although most tended to be high. Specificity values exhibited a similar pattern, ranging from 0.52 to 1.0. In comparison with visual assessment methods, the DD exhibited a sensitivity value that was almost always higher and a specificity value that was almost always lower. The body of evidence is characterized largely by in vitro studies, so that generalization to the clinical setting is uncertain. Because caries thresholds varied substantially across the studies, synthesized estimates of performance were not possible. CONCLUSIONS AND CLINICAL IMPLICATIONS The DD clearly is more sensitive than traditional diagnostic methods; however, the increased likelihood of false-positive diagnoses compared with that with visual methods limits its usefulness as a principal diagnostic tool.

Abstract
BACKGROUND Identifying posterior teeth that are at heightened risk of developing cusp fracture is an inexact science. Risk indicators based on controlled observations are not available, and dentists' assessments vary. METHODS The authors conducted a case-control study of cusp fracture in restored posterior teeth. They evaluated 39 potential risk indicators identified in previous uncontrolled studies for an association with fracture in 200 patients with fractures and 252 patients without fractures. These risk indicators delineated patients' clinical characteristics and behaviors, as well as clinical characteristics of individual teeth. The authors used logistic regression to develop models identifying risk indicators associated with fracture, both between case and control subjects and between case and comparison teeth in case subjects. RESULTS Two risk indicators appeared in both models. The presence of a fracture line and an increase in the proportion of the volume of the natural tooth crown occupied by the restoration substantially increased the odds of fracture (P < .001). Additional risk indicators were unique to the case subject-control subject model, including subject age and other measures related to the relative size of the restoration or to loss of dentinal support. Neither patient behaviors such as clenching, grinding and biting hard objects nor occlusal characteristics such as guidance, cusp anatomy and general wear patterns were strong predictors of fracture risk. CONCLUSIONS Among posterior teeth with restorations, two clinical features were strongly associated with the risk of cusp fracture: presence of a fracture line in the enamel and proportional volume of the restoration. CLINICAL IMPLICATIONS Dentists assessing the risk of fracture should consider a detectable fracture line or a high ratio of restoration-to-total-crown volume as important indicators of elevated risk.

Abstract
CONTEXT Almost 20% of children aged 2 to 5 years have untreated dental caries. Physician interventions to prevent and manage dental caries in preschool children could help address this common problem. OBJECTIVE To review the evidence for effectiveness of five possible physician interventions- (1) screening and risk assessment, (2) referral, (3) provision of dietary supplemental fluoride, (4) application of fluoride varnish, and (5) counseling-for the prevention of dental caries for the U.S. Preventive Services Task Force. DATA SOURCES Articles from 1966 to 2001 addressing the effectiveness of primary care clinicians' interventions to prevent or manage dental caries were identified in MEDLINE. The evidence for effectiveness of supplemental fluorides, fluoride varnish, and counseling for caries prevention performed by dental personnel was also examined through existing and new systematic reviews. DATA SYNTHESIS For most key questions related to the five interventions, the evidence for primary care clinician effectiveness was rated as poor owing to the scarcity of studies. Ten surveys of physicians' knowledge and behavior about fluoride supplementation provided fair evidence, suggesting that supplementation decisions were often made without consideration of other fluoride exposures. Reviews of the dental literature identified fair evidence supporting the effectiveness of both fluoride supplements and varnish, although information describing effectiveness and adverse outcomes of supplementation with the most recent dosage schedule is not available. CONCLUSIONS Evidence for the effectiveness of traditionally recommended primary care clinician interventions (screening, referral, counseling) to prevent dental caries in preschool children is lacking. There is fair evidence for the effectiveness of two fluoride-based interventions (fluoride supplementation and varnish) applicable in primary care practice. However, there is also fair evidence indicating that physicians' consideration of fluoride exposure is incomplete, thus increasing the risk for fluorosis among those prescribed supplements.

Abstract
Although posterior cusp fracture occurs frequently, its consequences are not well-delineated. This study recorded short-term outcomes (distribution of fractured teeth and cusps, fracture severity, and treatment received up to two years postfracture) for 517 fractured teeth from 498 subjects at a large group practice. Maxillary and mandibular tooth fractures occurred with similar frequency. In the maxillary arch, first and second molars and premolars fractured with roughly the same frequency; premolar fractures were more severe. In the mandible, first molars accounted for approximately 50% of all fractures and were most likely to be severe fractures. Nonholding cusps were more likely to fracture in both arches. Proportions of fractured teeth receiving "catastrophic" treatment were low (3% extraction; 4% endodontic treatment) and the large majority of fractured teeth were treated in a single visit using direct restorative materials. A knowledge of the relatively small proportions of fractured teeth that suffer serious consequences and the tooth-specific distributions of cusp fracture should help dentists and patients to make informed decisions regarding preventive restorative intervention prior to fracture.

Abstract
BACKGROUND Evidence-based dentistry, or EBD, is not a new concept for the dental profession in the United States. The American Dental Association has long relied on credible scientific evidence in setting policy and communicating with dentists and the general public. EBD provides an approach to oral health care that follows a process of systematically collecting and analyzing scientific evidence to answer a specific clinical question. OVERVIEW The authors discuss applications of systematic review findings to everyday clinical practice and explore the implications of EBD for dental education, clinical research and the provision of care to patients. CONCLUSIONS AND PRACTICE IMPLICATIONS In developing appropriate treatment plans, dentists should combine the patient's treatment needs and preferences with the best available scientific evidence, in conjunction with the dentist's clinical expertise. To keep pace with other health professions in building a strong evidence-based foundation, dentistry will require significant investments in clinical research and education to evaluate the best currently available evidence in dentistry and to identify new information needed to help dentists provide optimal care to patients.

Abstract
BACKGROUND Risk-based prevention is a means of ensuring that patients receive preventive treatment appropriate for their risk of disease. While straightforward, its application in private practice has not been examined. METHODS Volunteer clinicians in 15 offices participated in a six-month pilot study to test methods for a larger, risk-based prevention demonstration study operated by a dental insurer. Concomitant with oral examinations for patients of this insurer, clinicians identified patients at elevated risk of developing dental caries and periodontitis. For these patients, the reasons for elevated risk (risk indicators), as well as planned preventive treatment in response to that risk, were recorded and transmitted to the insurer via the claim form. RESULTS The clinicians identified relatively small percentages of patients as being at high risk of developing caries (4 percent) and periodontitis (7 percent), with little variation across the 15 offices. Larger proportions of patients were identified as being at moderate risk of developing caries (29 percent) and periodontitis (30 percent), with more extensive variation across offices. In general, patients classified as being at elevated risk had received more disease-related treatment than patients at low risk before the classification, which provided some validation for the accuracy of risk assessment. CONCLUSIONS The results of this pilot study suggest that formal, risk-based prevention can be accomplished in dental offices. Clinicians' reported risk assignments and indicators, together with their planned preventive treatments, demonstrate a good understanding of risk-based prevention. CLINICAL IMPLICATIONS Researchers may need to clarify the criteria used to assess moderate risk of developing dental caries, and clinicians may need to emphasize greater use of fluorides and more frequent recall visits for adults at elevated risk of developing dental caries.

Abstract
STATEMENT OF PROBLEM Many dentists cite the fracture risk posed by a large existing restoration as a primary reason for their decision to place a full-coverage restoration. However, there is poor agreement among dentists as to when restoration placement is necessary because of the inability to make objective measurements of restoration size. PURPOSE The purpose of this study was to compare a new method to estimate restoration volumes in posterior teeth with analytically determined volumes. MATERIAL AND METHODS True restoration volume proportion (RVP) was determined for 96 melamine typodont teeth: 24 each of maxillary second premolar, mandibular second premolar, maxillary first molar, and mandibular first molar. Each group of 24 was subdivided into 3 groups to receive an O, MO, or MOD amalgam preparation design. Each preparation design was further subdivided into 4 groups of increasingly larger size. The density of amalgam used was calculated according to ANSI/ADA Specification 1. The teeth were weighed before and after restoration with amalgam. Restoration weight was calculated, and the density of amalgam was used to calculate restoration volume. A liquid pycnometer was used to calculate coronal volume after sectioning the anatomic crown from the root horizontally at the cementoenamel junction. True RVP was calculated by dividing restoration volume by coronal volume. An occlusal photograph and a bitewing radiograph were made of each restored tooth to provide 2 perpendicular views. Each image was digitized, and software was used to measure the percentage of the anatomic crown restored with amalgam. Estimated RVP was calculated by multiplying the percentage of the anatomic crown restored from the 2 views together. Pearson correlation coefficients were used to compare estimated RVP with true RVP. RESULTS The Pearson correlation coefficient of true RVP with estimated RVP was 0.97 overall (P</=.0001). Coefficients for comparisons stratified by tooth type, restoration type, and restoration size groups were all greater than 0.90 (P</=.0001). CONCLUSION Within the limitations of this study, the high correlation between estimated RVP and true RVP indicated that estimated RVP was an accurate method to quantify the relative volume of restorative material in coronal tooth structure. The fact that it can be done in a nondestructive manner makes it attractive for clinical situations.

Abstract
This systematic review evaluates evidence describing histologically validated performance of methods for identifying carious lesions. A search identified 1,407 articles, of which 39 were included that described 126 assessment of visual, visual/tactile, radiographic (film and digital), fiber optic transillumination, electrical conductance, and laser fluorescence methods. A subsequent update added four studies contributing 10 assessments. The strength of the evidence was judged to be poor for all applications, signifying that the available information is insufficient to support generalizable estimates of the sensitivity and specificity of any given application of a diagnostic method. The literature is problematic with respect to complete reporting of methods, variations in histological validation methods, the small number of in vivo studies, selection of teeth, small numbers of examiners, and other factors threatening both internal and external validity. Future research must address these problems as well as expand the range of assessments to include primary teeth and root surfaces.

Abstract
OBJECTIVE A systematic review was conducted to identify any additional risks of adverse cardiovascular outcomes to hypertensive individuals represented by use of epinephrine-containing anesthetic solutions and epinephrine-impregnated retraction cords. STUDY DESIGN Two searches identified 373 local anesthetic and 33 retraction cord reports; 6 local anesthetic reports met inclusion criteria. RESULTS Use of epinephrine in uncontrolled hypertensive patients was associated with small, nonsignificant increases in systolic and diastolic blood pressure. No adverse outcomes were reported. Only one study examined effects of epinephrine on controlled hypertensive patients, in whom additional risks due to interactions with antihypertensive medication are possible. Available studies did not address effects of gingival retraction cord on hypertensive patients. CONCLUSIONS Although the increased risk for adverse events among uncontrolled hypertensive patients was found to be low and the reported occurrence of adverse events in hypertensive patients associated with the use of epinephrine in local anesthetics was minimal, the quantity and quality of the pertinent literature is problematic.

Abstract
BACKGROUND Depression has been associated with periodontal disease; however, its relationship to periodontal treatment outcome (PTO) has not been investigated. METHODS Data were obtained by chart abstraction and computer databases on 1,299 health maintenance organization (HMO) patients aged 30 to 64 who had concurrent medical, dental, and pharmacy benefits, and who had an initial periodontal examination during 1996, 1997, or 1998. Depression (yes/no) was the main independent variable and was determined by presence of any diagnosis code for depression on the patient record. PTO was determined by the difference in percent of sites with probing depth (PD) > or = 5 mm between the initial and 1-year post-treatment periodontal exams. Sub-median periodontal treatment outcome (SMPTO) was defined as a reduction in fewer than the median percent of sites (7.33%) with PD > or = 5 mm. Information on sociodemographics, periodontal therapy, calculus and plaque, number of remaining teeth, smoking, antidepressant medications, and diabetes were collected. RESULTS A total of 697 patients had a periodontal exam at both baseline and follow-up. Of these, 12.2% had depression. In a multivariable logistic model, depression (odds ratio [OR] 2.16, 95% confidence interval [Cl] 1.12 to 4.16) and 4-month recall treatment (OR 2.34, Cl 1.46 to 3.75) were associated with SMPTO, while percent of sites at baseline with PD > or = 5 mm (OR 0.93, Cl 0.91 to 0.94), number of remaining teeth at baseline (OR 0.94, Cl 0.89 to 0.99), and number of teeth lost during the study period (OR 0.75, Cl 0.58 to 0.96) were negatively associated. Periodontal surgery, age, gender, smoking, plaque, calculus, diabetes, and antidepressant medication were not significant in the model. CONCLUSION Clinical depression may have a negative effect on periodontal treatment outcome in this group model HMO population.

Abstract
A systematic review of the periodic scientific literature was undertaken to determine the strength of the evidence for the efficacy of professional caries preventive methods applied to high risk individuals, and the efficacy of professionally applied methods to arrest or reverse non-cavitated carious lesions. An initial search identified 1435 articles, of which 27 were eventually included in the review. Among the 22 studies addressing the prevention of carious lesions in caries-active or high risk individuals, the strength of the evidence was judged to be fair for fluoride varnishes and insufficient for all other methods. Among the seven studies addressing the management of non-cavitated carious lesions, the strength of the evidence for efficacy was judged to be insufficient for all methods. The results do not indicate that the preventive and management methods reviewed are not efficacious; rather, they demonstrate that not enough is known to determine the efficacy of the methods. Suggestions for strengthening the limited evidence base involve the following: i) increasing the number of studies that examine prevention among high risk individuals and non-surgical management of non-cavitated lesions, ii) including a wider variety of subject ages, iii) targeting aspects of the efficacy questions not yet addressed, iv) strengthening research methods employed in the studies, and v) reporting methods and outcomes more completely.

Abstract
Bounded edentulous spaces (BES)-a missing posterior tooth with intact adjacent teeth-are thought to lead to arch collapse resulting from the movement of adjacent teeth. To determine the rate of change in distance between teeth adjacent to a BES, we examined three successive measurable radiographs of 116 untreated posterior BES cases. The distance between the teeth (DBT) adjacent to the space was measured, and change in DBT (delta DBT) between pre-extraction and follow-up radiographs was calculated. We used linear spline regression to construct models for tooth movement and to identify factors associated with delta DBT. The mean delta DBT was < 1 mm during the first year post-extraction, and the DBT continued to decrease at a successively slower rate each following year. Overall and for each tooth type, the greatest rates of decrease in DBT were seen in the zero to two-year period. In a multivariable model, time since extraction and tooth type were significantly associated with delta DBT. These findings suggest that movement of teeth adjacent to a posterior BES after the first two years is usually gradual and minor within the time frame of this study.

Abstract
OBJECTIVES Although complete cusp fracture is acknowledged to occur frequently, incidence rates have been reported rarely. This study determined incidence rates for complete coronal cusp fracture per person and per tooth type. METHODS All fractures presenting among enrollees in a dental health maintenance organization using two geographically isolated clinics were noted for 105 days. For a sample of these enrollees, likelihood of attending the clinic in the event of a fracture was assessed through a telephone survey, and the at-risk status of all teeth was determined through a record survey. Incidence rates were calculated for persons, and for individual tooth types for all complete fractures and for non-carious complete fractures. In addition, for posterior teeth the distribution of fractured cusps, and the severity of fractures were examined. RESULTS Per-person incidence rates for complete coronal fractures for all teeth were 89.0 and 72.7 per 1000 person years, respectively, for all fractures and for non-carious fractures. The rates for all anterior and all posterior teeth were 10.2 and 69.9, respectively, for all non-carious fractures. In mandibular posterior teeth, lingual cusps fractured twice as frequently as facial cusps, while the opposite was true for maxillary premolars. Among maxillary molars, the mesiofacial and distolingual cusps fractured most frequently. The large majority of fractures exposed dentin (95%), while pulpal exposure occurred infrequently (3%). A minority of fractures extended below the gingival crest (24%) or the DEJ (25%). CONCLUSIONS This is the first report of fracture incidence rates for enumerated persons and teeth at risk and as such helps define the magnitude of the problem for dentists and their patients.
