Correlates of root caries experience in middle-aged and older adults in the Northwest Practice-based REsearch Collaborative in Evidence-based DENTistry research network

BackgroundThe authors examined the correlates of root caries experience for middle-aged adults (aged 45–64 years) and older adults (65 years and older) to test the hypothesis that the factors related to root caries are different for middle-aged adults than they are for older adults.MethodsThe authors conducted an observational cross-sectional study that focused on adult patients aged 45 to 97 years recruited from the Northwest Practice-based REsearch Collaborative in Evidence-based DENTistry research network (N = 775). The outcome variable was any root caries experience (no/yes). The authors hypothesized that sociodemographic, intra- oral and behavioral factors were root caries correlates. The authors used Poisson regression models to generate overall and age-stratified prevalence ratios (PRs) of root caries, and they used generalized estimating equations to account for practice-level clustering of participants.ResultsA total of 19.6 percent of adults had any root caries. A dentist’s assessment that the patient was at high risk of developing any caries was associated with greater prevalence of root caries experience in both middle-aged adults (PR, 2.70; 95 percent confidence interval [CI], 1.63–4.46) and older adults (PR, 1.87; 95 percent CI, 1.19–2.95). The following factors were associated significantly with increased root caries prevalence but only for middle-aged adults: male sex (P = .02), self-reported dry mouth (P < .001), exposed roots (P = .03) and increased frequency of eating or drinking between meals (P = .03). No other covariates were related to root caries experience for older adults.ConclusionsWithin a practice-based research network, the factors associated with root caries experience were different for middle-aged adults than they were for older adults. Research is needed to identify relevant root caries correlates for adults 65 years and older.Practical ImplicationsInterventions aimed at preventing root caries are likely to be different for middle-aged adults than for older adults. Dentists should use root caries prevention programs that address appropriate aged-based risk factors.     

Comparison of the intakes of sugars by young children with and without dental caries experience

BACKGROUND: Relationships among sugars and dental caries in contemporary societies are unclear. The authors describe young children's intakes of nonmilk extrinsic (NME) and intrinsic/milk sugars and relate those intakes to dental caries. METHODS: The authors conducted cross-sectional analyses of dietary data collected from the Iowa Fluoride Study using three-day diaries for subjects at ages 1, 2, 3, 4 and 5 years and for subjects aged 1 through 5 years according to dental caries experience at 4.5 to 6.9 years of age. They categorized foods and beverages as containing NME or intrinsic/milk sugars. RESULTS: Subjects' total, NME, food NME and intrinsic/milk sugars intakes at ages studied did not differ between subjects with and without caries experience. Beverage NME sugars intakes at age 3 years predicted caries (P < .05) in logistic regression models adjusted for age at dental examination and for fluoride intake. CONCLUSIONS: Dental caries is a complex, multifactorial disease process dependent on the presence of oral bacteria, a fermentable carbohydrate substrate and host enamel. A simple NME-intrinsic/milk sugars categorization appears insufficient to capture the complex dietary component of the caries process. CLINICAL IMPLICATIONS: Cariogenicity is more likely a function of the food and/or beverage vehicle delivering the sugar and the nature of exposure-that is, frequency and length of eating events-than of the sugar's categorization.     

Preventing dental caries associated with sugar-sweetened beverages

BackgroundDietary intake of sugar-sweetened beverages (SSBs) has increased during the past 30 years, and SSB intake is associated with caries.

ConclusionsSSBs vary in the quantity and nature of sugars they contain; however, all of the sugars are fermentable by oral bacteria and potentially cariogenic.Practical ImplicationsOral health care practitioners should assess patients’ SSB intakes by asking questions regarding the quantity, frequency and duration of SSB intake. In response to individual behaviors, practitioners should tailor recommendations when providing anticipatory guidance to help patients decrease their exposure to SSBs for caries prevention. In light of the association between SSB intake and caries risk, as well as the increased consumption of SSBs, all dental practices should assess patients’ SSBs intake.     

Screening for diabetes mellitus in dental practices: A field trial

BackgroundIn this field trial, the authors assess the feasibility of screening for diabetes and prediabetes in dental practices and in a community health center.MethodsDental patients 45 years and older who were not aware of their diabetic status underwent evaluation for diabetes risk with an American Diabetes Association Diabetes Risk Test and with hemoglobin (Hb) A_1c measurement. Participants with an HbA_1c level of 5.7 percent or greater were referred to their physicians for diagnosis.ResultsOf the 1,022 patients screened, 416 (40.7 percent) had an HbA_1c blood level of 5.7 percent or greater and were referred for diagnosis. The HbA_1c and the American Diabetes Association Diabetes Risk Test were correlated (P < .001). Of the 416 participants who were referred, 35.1 percent received a diagnosis from their physicians within one year; 78.8 percent of these patients were seen in the community health center and 21.4 percent were seen in private dental offices. The diagnoses were diabetes (12.3 percent of patients), high risk of developing diabetes (that is, prediabetes) (23.3 percent) and no diabetes (64.4 percent).ConclusionsThe study results show that screening for prediabetes and diabetes is feasible in a dental office, with acceptance by the dentist and dental office staff members, patients&apos; physicians and patients. Patients from the community health center demonstrated good compliance with referrals to physicians; however, compliance was poor among those in the private dental offices.Practical ImplicationsScreening for diabetes and prediabetes in the dental office may provide an important benefit to patients and encourage interprofessional collaboration to achieve a chronic care model in which health care professionals work together to care for a panel of patients.     

Chemomechanical caries removal in children: an operator's and pediatric patients' responses

BACKGROUND: This study investigated an operator's and pediatric patients' responses to chemo-mechanical caries removal (CMCR) versus the traditional method (TM) of caries removal using a handpiece and a round bur when treating dentinal-depth occlusal lesions with minimal enamel access in primary molars. METHODS: Data were collected from 50 children at baseline and before, during and after caries removal using CMCR or TM. The subjects in the CMCR group were on average younger than the subjects in the TM group and had more deep lesions. RESULTS: The operator rated CMCR as needing more clinical and technical effort and more total effort than TM. He was less satisfied with CMCR than with TM. Subjects in the CMCR group perceived the time needed for treatment as significantly longer than did the subjects in the TM group. Fear of the dentist decreased in subjects in the TM group from before to after the operative appointment, while it increased in subjects in the CMCR group. CONCLUSIONS: The authors found no direct advantage in using CMCR over using TM. CLINICAL IMPLICATIONS: CMCR cannot be recommended as an alternative to TM when treating dentinal depth occlusal lesions with minimal access in primary molars.     

Early childhood caries screening tools: a comparison of four approaches

BackgroundEarly childhood caries (ECC) is prevalent and consequential. Risk assessment tools have been proposed that can be used to identify children who require intensive interventions. In this study, the authors compare four approaches for identifying children needing early and intensive intervention to prevent or minimize caries experience for their accuracy and clinical usefulness.MethodsThe authors screened 229 predominantly low-income Hispanic children younger than 3 years with ECC and 242 without ECC by using the American Academy of Pediatric Dentistry's Caries-risk Assessment Tool (CAT) and the optional screening measure of culturing Streptococcus mutans. The authors compared four approaches (CAT, CAT minus socioeconomic status, CAT minus socioeconomic status plus mutans streptococci [MS] and MS alone) for accuracy and clinical usefulness.ResultsThe results of the CAT demonstrated high sensitivity (100.0 percent) and negative predictive value (NPV) (100.0 percent) but low specificity (2.9 percent) and positive predictive value (PPV) (49.4 percent). The MS culture alone had the highest combination of accuracy and clinical usefulness (sensitivity, 86.5 percent; specificity, 93.4 percent; PPV, 92.5 percent; NPV, 87.9 percent). When we removed the socioeconomic status element, the CAT's performance improved.ConclusionsSalivary culture of MS alone in a population of young, low-income Hispanic childrenoutperformed the CAT and variations on the CAT for test accuracy (sensitivity and specificity) and clinical usefulness (predictive values).Clinical ImplicationsScreening for ECC by using salivary MS cultures and variations on the CAT are promising approaches for identifying children who need early and intensive intervention to prevent or minimize caries experience.     

The effect of dental sealants on bacteria levels in caries lesions: a review of the evidence

BACKGROUND: Concern about inadvertently sealing over caries often prevents dentists from providing dental sealants. The objective of the authors' review was to examine the effects of sealants on bacteria levels within caries lesions under dental sealants. METHODS: The authors searched electronic databases for comparative studies examining bacteria levels in sealed permanent teeth. To measure the effect of sealants on bacteria levels, they used the log(10) reduction in mean total viable bacteria counts (VBC) between sealed and not-sealed caries and the percentage reduction in the proportion of samples with viable bacteria. RESULTS: Six studies--three randomized controlled trials, two controlled trials and one before-and-after study-were included in the analysis. Although studies varied considerably, there were no findings of significant increases in bacteria under sealants. Sealing caries was associated with a 100-fold reduction in mean total VBC (four studies, 138 samples). Sealants reduced the probability of viable bacteria by about 50.0 percent (four studies, 117 samples). CONCLUSIONS: The authors found that sealants reduced bacteria in carious lesions, but that in some studies, low levels of bacteria persisted. These findings do not support reported concerns about poorer outcomes associated with inadvertently sealing caries. CLINICAL IMPLICATIONS: Practitioners should not be reluctant to provide sealants-an intervention proven to be highly effective in preventing caries-because of concerns about inadvertently sealing over caries.     

Metabolic syndrome: pathogenesis, medical care and dental implications

BACKGROUND: The dental literature contains little information about metabolic syndrome (MetS) and its dental implications. TYPES OF STUDIES REVIEWED: The authors conducted a MEDLINE search for the period 2000 through 2005, using the term "metabolic syndrome" to define its pathophysiology, medical treatment and dental implications. RESULTS: MetS is the co-occurrence of abdominal obesity, hyper-triglyceridemia, reduced high-density lipoprotein cholesterol levels, hypertension and impaired fasting glucose, which results from consumption of a high-calorie diet and decreased levels of physical activity superimposed on the appropriate genetic setting. Components of MetS synergistically promote the development of atherosclerosis, resulting in myocardial infarction and stroke. CLINICAL IMPLICATIONS: Deteriorating oral health status is associated with worsening of the atherogenic profile. Tooth loss often results in chewing difficulties because of inadequate occlusive surfaces and may lead to alterations in food selection and dietary quality. This, in turn, adversely affects body composition and nutritional status, both of which are related to vascular health. Dentists should develop treatment plans that preserve and restore the dentition, thus ensuring maximum masticatory efficiency and affording patients the optimum opportunity to consume food that will not foster atherogenesis.     

The impact of the Great Recession on untreated dental caries among kindergarten students in North Carolina

BackgroundThe authors conducted a study to determine the impact of the Great Recession on untreated dental caries in kindergarten-aged children in North Carolina (NC).MethodsDuring the seven school years from 2003–2004 through 2009–2010, the state dental public health program assessed 608,339 kindergarten students for untreated decayed primary teeth (dt) as part of the statewide public health surveillance system. The authors aggregated observations to the school level and matched 7,660 school-year observations for 1,215 schools to National School Lunch Program (NSLP) participation rates, their primary economic indicator of the Great Recession. The authors included additional county-level economic indicators and measures of dentist supply and Medicaid enrollment. They used ordinary least squares regression with school-and year-fixed effects to examine the association of variables with the proportion of children with more than one dt for all schools and for schools with a greater than 10 percent increase in NSLP participation after 2006.ResultsThe authors found a small but statistically significant association between the proportion of children in the schools participating in the NSLP and the proportion of kindergarten students who had more than one dt (β, 0.031; 95 percent confidence interval [CI], 0.001 to 0.0604). This association was greater in schools that had a greater than 10 percent increase in NSLP participation (β, 0.068; 95 percent CI, ?0.007 to 0.143). Regression estimates indicate a 1.3– and 3.1–percentage point cumulative increase in the proportion of children with more than one dt during the period from 2008 through 2009 for all schools and high-risk schools, respectively.ConclusionIncreased NSLP enrollment was associated with less treatment for dental caries in 5-year-old children.Practical ImplicationsFewer children are receiving needed dental treatment because of the Great Recession. Recent gains made in the treatment of dental caries in children in NC have slowed as a result.     

Breastfeeding: An overview of oral and general health benefits

Background

Breastfeeding is the reference against which alternative infant feeding models must be measured with regard to growth, development and other health outcomes. Although not a systematic review, this report provides an update for dental professionals, including an overview of general and oral health–related benefits associated with breastfeeding.Types of Studies ReviewedThe authors examined the literature regarding general health protections that breastfeeding confers to infants and mothers and explored associations between breastfeeding, occlusion in the primary dentition and early childhood caries. To accomplish these goals, they reviewed systematic reviews when available and supplemented them with comparative studies and with statements and reports from major nongovernmental and governmental organizations.ResultsWhen compared with health outcomes among formula-fed children, the health advantages associated with breastfeeding include a lower risk of acute otitis media, gastroenteritis and diarrhea, severe lower respiratory infections, asthma, sudden infant death syndrome, obesity and other childhood diseases and conditions. Evidence also suggests that breastfed children may develop a more favorable occlusion in the primary dentition. The results of a systematic review in which researchers examined the relationship between breastfeeding and early childhood caries were inconclusive.Conclusions and Clinical ImplicationsThe American Academy of Pediatric Dentistry, Chicago, suggests that parents gently clean infants' gums and teeth after breastfeeding. The American Academy of Pediatrics, Elk Grove Village, Ill., recommends that breastfeeding should be exclusive for about the first six months of life and should continue, with the introduction of appropriate complementary foods, to at least age 12 months or beyond, as desired by mother and child. Dentists and staff members can take steps to ensure they are familiar with the evidence and guidelines pertaining to breastfeeding and to oral health. They are encouraged to follow the surgeon general's recommendations to promote and support optimal breastfeeding and oral health practices among their patients.     

Risk of adrenal crisis in dental patients: Results of a systematic search of the literature

BackgroundThe authors performed a systematic search of the literature to identify the frequency of, risk of experiencing and factors associated with adrenal crises in dental patients.MethodsThe authors searched PubMed and Ovid MEDLINE (1947-June 20, 2012) and Embase (1974-2012) for English-language articles related to cases of adrenal crisis in dentistry and extracted and analyzed data from the articles. The six authors determined whether the cases identified met a consensus definition of adrenal crisis.ResultsOf 148 articles identified in the initial screening, 34 articles were included in the final review, from which six cases met the criteria of adrenal crisis. The authors categorized four cases as “suggestive of adrenal crisis” and two cases as “consistent with adrenal crisis.” Risk factors were significant adrenal insufficiency, pain, infection, having undergone an invasive procedure, having received a barbiturate general anesthetic, and poor health status and stability at the time of presentation. The authors estimated risk to be less than one in 650,000 in patients with adrenal insufficiency.ConclusionsAdrenal crisis is rare in dental patients, with only six reports of it having been published in the past 66 years. Risk is associated with unrecognized adrenal insufficiency, poor health status and stability at the time of treatment, pain, infection, having undergone an invasive procedure and having received a barbiturate general anesthetic.Clinical ImplicationsRisk of adrenal crisis is reduced through proper evaluation of the patient, identification of risk factors and following appropriate preventive measures.     

A usability evaluation of four commercial dental computer-based patient record systems

BackgroundThe usability of dental computer-based patient record (CPR) systems has not been studied, despite early evidence that poor usability is a problem for dental CPR system users at multiple levels.MethodsThe authors conducted formal usability tests of four dental CPR systems by using a purposive sample of four groups of five novice users. The authors measured task outcomes (correctly completed, incorrectly completed and incomplete) in each CPR system while the participants performed nine clinical documentation tasks, as well as the number of usability problems identified in each CPR system and their potential relationship to task outcomes. The authors reviewed the software application design aspects responsible for these usability problems.ResultsThe range for correctly completed tasks was 16 to 64 percent, for incorrectly completed tasks 18 to 38 percent and for incomplete tasks 9 to 47 percent. The authors identified 286 usability problems. The main types were three unsuccessful attempts, negative affect and task incorrectly completed. They also identified six problematic interface and interaction designs that led to usability problems.ConclusionThe four dental CPR systems studied have significant usability problems for novice users, resulting in a steep learning curve and potentially reduced system adoption.Clinical ImplicationsThe significant number of data entry errors raises concerns about the quality of documentation in clinical practice.     

Twenty-month follow-up of occlusal caries lesions deemed questionable at baseline: Findings from The National Dental Practice-Based Research Network

Background.A questionable occlusal caries (QOC) lesion can be defined as an occlusal surface with no radiographic evidence of caries, but caries is suspected because of clinical appearance. In this study, the authors report the results of a 20-month follow-up of these lesions.Methods.Fifty-three clinicians from The National Dental Practice-Based Research Network participated in this study, recording lesion characteristics at baseline and lesion status at 20 months.Results.At baseline, 1,341 QOC lesions were examined; the treatment that was planned for 1,033 of those at baseline was monitoring (oral hygiene instruction, applying or prescribing fluoride or varnish, or both), and the remaining 308 received a sealant (n = 192) or invasive therapy (n = 116). At the 20-month visit, clinicians continued to monitor 927 (90 percent) of the 1,033 monitored lesions. Clinicians decided to seal 61 (6 percent) of the 1,033 lesions (mean follow-up, 19 months) and invasively treat 45 (4 percent) of them (mean follow-up, 15 months). Young patient age (< 18 years) (odds ratio = 3.4; 95 percent confidence interval, 1.7-6.8) and the lesion&apos;s being on a molar (odds ratio = 1.8; 95 percent confidence interval, 1.3-2.6) were associated with the clinician&apos;s deciding at some point after follow-up to seal the lesion or treat it invasively.Conclusions.Almost all (90 percent) QOC lesions for which the treatment planned at baseline was monitoring still were planned to undergo monitoring after 20 months. This finding suggests that noninvasive management is appropriate for these lesions.Practical Implications.Previous study results from baseline indicated a high prevalence of QOC lesions (34 percent). Clinicians should consider long-term monitoring when making treatment decisions about these lesions.     

Concordance between clinical practice and published evidence: Findings from The National Dental Practice-Based Research Network

BackgroundDocumenting 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”).MethodsNetwork 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.ResultsThe 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).ConclusionDentists reported a medium-range concordance between practice and published evidence.Practical ImplicationsEfforts to bring research findings into routine practice are needed.     

Assessment of treatment provided by dental health aide therapists in Alaska: a pilot study

BackgroundDental health aide therapists (DHATs) in Alaska are authorized under federal law to provide certain dental services, including irreversible dental procedures. The author conducted this pilot study to determine if treatments provided by DHATs differ significantly from those provided by dentists, to determine if DHATs in Alaska are delivering dental care within their scope of training in an acceptable manner and to assess the quality of care and incidence of reportable events during or after dental treatment.MethodsThe author audited the dental records of patients treated by dentists and DHATs who perform similar procedures for selected variables. He reviewed the records of 640 dental procedures performed in 406 patients in three health corporations.ResultsThe author found no significant differences among the provider groups in the consistency of diagnosis and treatment or postoperative complications as a result of primary treatment. The patients treated by DHATs had a mean age 7.1 years younger than that of patients treated by dentists, and the presence or adequacy of radiographs was higher among patients treated by dentists than among those treated by DHATs, with the difference being concentrated in the zero- to 6-year age group.ConclusionsNo significant evidence was found to indicate that irreversible dental treatment provided by DHATs differs from similar treatment provided by dentists. Further studies need to be conducted to determine possible long-term effects of irreversible procedures performed by nondentists.Clinical ImplicationsA need to improve oral health care for American Indian/Alaska Native populations has led to an approach for providing care to these groups in Alaska. The use of adequately trained DHATs as part of the dental team could be a viable long-term solution.
