Evidence-Based Dentistry Caries Risk Assessment and Disease Management

Caries Experience before and after COVID-19 Restrictions: An Observational Study

Background: The declaration of COVID-19 as a pandemic by the World Health Organization in 2020 led to the suspension of several clinical practices globally, including dentistry. This study investigates the impact of these restrictions on dental caries experience. Methods: A retrospective cross-sectional study was conducted at Egas Moniz University's dental hospital in the Lisbon Metropolitan Area from June 2019 to June 2021. The study involved 3380 participants who were divided into two cohorts: after and before COVID-19 restrictions. Data collection included a questionnaire, full-mouth clinical examinations, and radiographs (panoramic X-rays, bitewings). Results: Before the COVID-19 restrictions, the prevalence of dental caries was 91.8%, with an average DMFT (decayed, missing, and filled teeth) index of 12.13. Post-restrictions, the prevalence decreased to 84.5%, with a DMFT index of 10.99. There was an increase in missing teeth and a decrease in decayed and filled teeth. Additionally, the frequency of toothbrushing declined among participants. Conclusions: The COVID-19 pandemic restrictions have significantly impacted dental caries experiences and oral health, highlighting a decrease in dental caries, but also a concerning reduction in oral hygiene practices. These results emphasize the importance of customized dental healthcare during public health emergencies to reduce impacts and maintain oral health.

Association of Papacarie Duo® and low-level laser in antimicrobial photodynamic therapy (aPDT)

Dental caries is a multifactorial, non-communicable disease. Effective treatment options for minimally invasive removal of carious tissue include Papacarie Duo® gel and antimicrobial photodynamic therapy (aPDT). aPDT involves a combination of a light source and photosensitizer. Given that Papacarie Duo® contains a percentage of blue dye, this study aims to explore the antimicrobial potential of Papacarie Duo® when associated with a light source against Streptococcus mutans strains. The chosen light source was a low-power diode laser (λ = 660 nm, E = 3 J, P = 100 mW, t = 30 s). To assess antimicrobial capacity, planktonic suspensions of Streptococcus mutans were plated on Brain Heart Infusion Agar (BHI) to observe the formation of inhibition halos. The studied groups included methylene blue (0.005%), Papacarie Duo®, distilled water (negative control), 2% chlorhexidine (positive control), Papacarie Duo® + laser, and methylene blue (0.005%) + laser. Following distribution onto plates, each group was incubated at 37 °C for 48 h under microaerophilic conditions. Inhibition halos were subsequently measured using a digital caliper. The results showed that chlorhexidine had the greatest antimicrobial effect followed by the group of irradiated methylene blue and irradiated Papacarie Duo®. All experimental groups demonstrated antimicrobial potential, excluding the negative control group. The study concludes that Papacarie Duo® exhibits antimicrobial properties when associated with a low-power diode laser.

Integration of an evidence-based caries management approach in dental education: The perspectives of dental instructors

PURPOSE/OBJECTIVES

Evidence-based caries management (EBCM) has developed into an internationally recognized tool for integration of comprehensive non-surgical caries treatment in dental education. However, uptake of the EBCM approach remains uneven across Canadian dental schools. Our project sought to understand how dental instructors perceive the challenges and solutions to the integration of the EBCM approach in undergraduate clinical education.

METHODS

Using a qualitative descriptive design, we recruited a purposeful sample of clinical instructors supervising undergraduate dental students in caries-related dental care. Semi-structured, online interviews focused on the main characteristics of EBCM. Interviews were analyzed using the awareness, desire, knowledge, ability, and reinforcement (ADKAR) change management model to understand challenges with EBCM implementation in undergraduate education. The analysis process started with verbatim transcription; then, transcripts were coded deductively based on the interview guide and the ADKAR model domains, and inductively to generate emergent codes. Finally, thematic analysis was used to develop themes and subthemes.

RESULTS

We interviewed 11 dental instructors with a wide range of clinical experience. Our results show that participants had sufficient awareness regarding the need for the EBCM approach and portrayed a strong desire to participate in bringing curricular changes. Knowledge and ability of participants depended on their training, experience, and involvement in continuing education courses. A lack of standardized caries management practices, less chairside time, and poor remuneration for instructors were major barriers in EBCM clinical implementation. Potential solutions suggested included providing continuing education courses, credits for students for non-surgical caries management, and remunerating instructors for implementation.

CONCLUSIONS

In conclusion, most participants were aware of the need for a substantive change toward EBCM and demonstrated the desire to participate and improve its implementation. Our analysis showed that to facilitate full integration of the EBCM approach into the undergraduate dental clinics, organizational focus needs to be placed on the individual's knowledge and ability, with tailored efforts toward reinforcement.

An interdisciplinary intervention program to prevent early childhood caries in the Dominican Republic

Objective

The principal aim of this randomized clinical trial (RCT) was to test the effectiveness in the prevention of Early Childhood Caries (ECC) through an educational intervention program with the use of a printed guide for pediatricians and parents both designed by pediatric dentists.

Materials and methods

After ethical approval, the first step was to design the educational guides, which were based on the information obtained from a focus group with pediatricians (n = 3), phone interviews with mothers to toddlers' (n = 7), and the best evidence available about children's oral health. For the RCT, 309 parents with their 10-12 months old children were randomly allocated to either the intervention or the control group. Parents in the intervention group received oral health education from the pediatricians supported by the printed guides. Parents in both groups received an oral health kit with a toothbrush and toothpaste at the first visit as well as at each 6-month follow-up visit. After 18 months the children were evaluated using ICDAS criteria.

Results

At baseline, data were available from 309 children (49.8% girls). The mean age of the children was of 10.8 months (SD = 0.8) and 69.3% had not had their teeth brushed with toothpaste. After 18 months, a total of 28 (22%) children in the intervention group and 44 (24%) in the control group were clinically examined. Regarding the number of tooth surfaces with caries lesions, the children in the intervention group had a mean of 6.50 (SD = 6.58) surfaces, while the children in the control group had a mean of 5.43 (SD = 4.74) surfaces with caries lesions. This difference was not significant (p = 0.460).

Conclusion

The RCT showed no effectiveness in caries-progression control. Despite this result, this study managed to identify barriers that do not allow pediatricians from offering parents adequate oral health recommendations. With this learning, it is possible to work on collaborative programs with pediatricians that over time likely will increase dental health by controlling for ECC.

Methods of Primary Clinical Prevention of Dental Caries in the Adult Patient: An Integrative Review

AIM

Preventive approaches to oral health diseases, mainly dental caries, require individual and collective policies. Thus, this review was conducted to identify the primary prevention methods of dental caries in adults to improve oral health at the clinical and community levels.

METHODS

This review followed the PICO strategy with the research question: "What are the methods of primary prevention of dental caries, in adults, for improving and maintaining oral health integrating clinical and community-based strategies?" Electronic screening was carried out by two independent reviewers in five databases (MedLine/PubMed, SciELO, Web of Science, Cochrane Library, and LILACS) to find relevant publications between 2015-2022. We applied eligibility criteria for selection of the articles. The following MeSH terms were used: "Primary Prevention"; "Adult"; "Oral Health"; "Dental Caries"; "Fluorides, Topical"; "Fluoride Varnishes"; "Pit and Fissure Sealants"; "Preventive Dentistry". Although the term "Prevention strategy" is not a MeSH descriptor, several correlated terms appeared and were used in the search engines: "Preventative Care", "Disease Prevention, Primary", and "Prevention, Primary". The tool provided by the JBI organization (Joanna Briggs Institute) was used to assess the quality of the included studies.

RESULTS

Nine studies were included. Overall, it was found that the main primary prevention methods applied in dentistry in adults are the application of pit and fissure sealants, topical application of fluoride performed in the dental clinic, use of fluoridated toothpaste, mouthwash with chlorhexidine at home, use of xylitol, the recommendation for regular appointments with the dentist, and the need to inform patients about the saliva buffer capacity and adoption of a non-cariogenic diet. For that purpose, preventive policies should be taken to prevent dental caries. These include three major challenges: providing the adult population with more knowledge regarding their oral health, empowering patients through adopting healthy lifestyles, and developing new preventive strategies and awareness campaigns aimed at the adult population to promote proper oral health habits.

CONCLUSIONS

A small number of studies were found whose participants were adult patients. There was some consistency regarding primary prevention methods in our studies. However, good quality randomized control studies are still required to define the best intervention strategies for adult caries prevention.

A mixed methods approach to obtaining health care provider feedback for the development of a Canadian pediatric dental caries risk assessment tool for children <6 years

Introduction

Early childhood caries (ECC) is a chronic but preventable disease affecting young children worldwide. Many young children face access to care barriers to early preventive dental visits for a variety of reasons, which can increase their risk for ECC. Non-dental primary health care providers are well positioned to assist in assessing a child's risk for ECC by performing caries risk assessment (CRA). The purpose of this project was to report on primary health care provider and stakeholder feedback in order to refine a drafted CRA tool for Canadian children &lt;6 years of age intended for use by non-dental primary health care providers.

Methods

In this mixed methods project, we conducted six focus groups with primarily non-dental primary health care providers followed by a short paper-based survey to quantify preferences and feedback. Data were thematically and descriptively analyzed.

Results

Participants’ feedback on the drafted CRA tool included the need for it to be relatively quick to complete, easy and practical to score, easy to implement into practitioners’ clinic schedules, and to include anticipatory guidance information to share with parents and caregivers. All participants (100%) welcomed a CRA tool. Many (85.4%) liked a layout that could be added to tools they already utilize. Most (73.2%) wanted the tool to be in colour, and many (90.2%) wanted the tool to include pictures.

Conclusion

Non-dental primary health care providers informed the final development and layout of the newly released Canadian CRA tool. Their feedback resulted in a user-friendly CRA tool with provider-patient dynamics and preferences.

Caries Experience and Risk Indicators in a Portuguese Population: A Cross-Sectional Study

Oral health surveys are essential for assessing the dental caries experience and to influence national policies. This retrospective cross-sectional study aims to analyze dental caries experience for which dental treatment was sought in a reference university dental hospital at the Lisbon Metropolitan Area between January 2016 and March 2020. Full-mouth examination, and sociodemographic, behavior, and medical information were included. Descriptive analyses and logistic regression analysis were applied to ascertain risk indicators associated with dental caries experience. A final sample of 9349 participants (5592 females/3757 males) were included, aged 18 to 99 years old. In this population, caries experience was 91.1%, higher in female participants. Age (OR = 1.01, 95% CI [1.00-1.02], occupation (OR = 2.94, 95% CI [2.37-3.65], OR = 3.35, 95% CI [2.40-4.67], OR = 2.55, 95% CI [1.66-3.91], for employed, unemployed, and retired, respectively), overweight (OR = 1.52, 95% CI [1.18-1.96]), reporting to have never visited a dentist (OR = 0.38, 95% CI [0.23-0.64], and self-reported week teeth status (OR = 2.14, 95% CI [1.40-3.28]) were identified as risk indicators for the presence of dental caries, according to adjusted multivariable logistic analyses. These results highlight a substantial rate of dental experience in a Portuguese cohort and will pave the way for future tailored oral public health programs in Portugal.

Direct restorations and enhanced caries prevention among 20- to 60-year-olds attending Helsinki City Public Dental Service - a register-based observation

OBJECTIVE

Our retrospective register-based observational study evaluated age-specific aspects and changes in volume and content of direct restorative procedures, pulp cappings and enhanced caries prevention measures given to adults.

METHODS

Data included all treatments provided for 20- to 60-year-olds visiting the Helsinki City Public Dental Service (PDS) in 2012 and 2017. For both years, the data were aggregated into 5-year age groups. Data included means of DMFT indices, number and size of direct restorations, number of specific codes for pulp cappings and enhanced prevention.

RESULTS

Around half of all patients received restorations, 39,820 (50.9%) in 2012 and 43,392 (45.9%) in 2017. The greatest increase in DMFT means by age cohort was found for the 2012 age cohort of 25- to 29-year-olds and the smallest for the 2012 age cohort of 45- to 49-year-olds. In each same-age group and each age cohort, the enhanced prevention in 2017 was less frequent than in 2012. The proportion of two-surface restorations accounted for 44.7% of procedures in 2012 and 45.9% in 2017, followed by an increasing proportion of one-surface restorations, from 28.3% in 2012 to 32.9% in 2017. Associations between restoration size and age group were highly significant (p < .001).

CONCLUSIONS

The volume of direct restorative procedures and enhanced prevention measures were strongly age-dependent. Restorative treatment procedures were more frequent in older age groups than in younger age groups, and vice versa for enhanced prevention and pulp cappings. The magnitude of restorative treatment decreased slowly from 2012 to 2017, and overall enhanced preventive treatment was limited.

Caries Management in Special Care Dentistry

The objective of this article is to provide a summary of the current evidence-based recommendations for caries management in patients with special health care needs (SHCNs). Considerations regarding caries risk assessment and preventive measures are also discussed with the goal of helping clinicians to manage the caries disease process using a person-centered approach and risk-based interventions. Importantly, most of the evidence is still based on the general population, because the evidence for those with SHCNs is still limited.

Expert consensus on dental caries management

Dental Caries is a kind of chronic oral disease that greatly threaten human being's health. Though dentists and researchers struggled for decades to combat this oral disease, the incidence and prevalence of dental caries remain quite high. Therefore, improving the disease management is a key issue for the whole population and life cycle management of dental caries. So clinical difficulty assessment system of caries prevention and management is established based on dental caries diagnosis and classification. Dentists should perform oral examination and establish dental records at each visit. When treatment plan is made on the base of caries risk assessment and carious lesion activity, we need to work out patient‑centered and personalized treatment planning to regain oral microecological balance, to control caries progression and to restore the structure and function of the carious teeth. And the follow-up visits are made based on personalized caries management. This expert consensus mainly discusses caries risk assessment, caries treatment difficulty assessment and dental caries treatment plan, which are the most important parts of caries management in the whole life cycle.

Analysis of quality, usefulness, reliability, visibility, and popularity of videos about dental caries on YouTube: A cross-sectional analysis

Objectives:

YouTube is the most popular social media and is widely used to access dental and oral diseases information. Nonetheless, the quality of online health information remains a problem. This study aimed to analyze the quality, usefulness, reliability, visibility, and popularity of YouTube videos about dental caries as a source of information.

Materials and Methods:

The study design was a cross-sectional analytical study. Here, 300 videos that were uploaded in September 2019–2020 were screened, and total duration, number of views, number of likes, number dislikes, uploader category (individual users or health professionals), and upload date of the videos were recorded. One hundred videos were analyzed in terms of their quality, usefulness, reliability, visibility, and popularity using the Global Quality Scale, usefulness score, DISCERN, viewing rate, and interaction index, respectively.

Results:

Videos were 78% uploaded by individual users. Videos uploaded by health professionals showed high scores in quality, usefulness, and reliability. Videos that were greater than 6 min long exhibited both better quality and higher popularity. Video with good-quality showed high visibility and popularity. In addition, videos with better usefulness and reliability showed high visibility; however, their popularity was low.

Conclusions:

Information about dental caries on YouTube is limited in quality. YouTube videos have a potentially important role in oral health education.

How can biophotonics help dentistry to avoid or minimize cross infection by SARS-CoV-2?

Biophotonics is defined as the combination of biology and photonics (the physical science of the light). It is a general term for all techniques that deal with the interaction between biological tissues/cells and photons (light). Biophotonics offers a great variety of techniques that can facilitate the early detection of diseases and promote innovative theragnostic approaches. As the COVID-19 infection can be transmitted due to the face-to-face communication, droplets and aerosol inhalation and the exposure to saliva, blood, and other body fluids, as well as the handling of sharp instruments, dental practices are at increased risk of infection. In this paper, a literature review was performed to explore the application of Biophotonics approaches in Dentistry focusing on the COVID-19 pandemic and how they can contribute to avoid or minimize the risks of infection in a dental setting. For this, search-related papers were retrieved from PubMED, Scielo, Google Schoolar, and American Dental Association and Centers for Disease Control and Prevention databases. The body of evidence currently available showed that Biophotonics approaches can reduce microorganism load, decontaminate surfaces, air, tissues, and minimize the generation of aerosol and virus spreading by minimally invasive, time-saving, and alternative techniques in general. However, each clinical situation must be individually evaluated regarding the benefits and drawbacks of these approaches, but always pursuing less-invasive and less aerosol-generating procedures, especially during the COVID-19 pandemic.

Current Novel Caries Diagnostic Technologies: Restorative Dentists' Attitude and Use Preferences

Early detection of caries lesions is key to a successful restorative dental treatment plan. The aim of this study was to investigate the preferences and attitude of graduate restorative dentistry residents (RDRs) regarding novel caries diagnostic technologies (NCDT) and to provide a brief overview of available technologies for both specialized and general dental practice. This cross-sectional study used an online questionnaire (17 questions) concerning RDRs’ attitude, preferences, and insights regarding five available NCDTs. It was distributed among twenty RDRs at a local government dental school following a review session about NCDTs. Collected responses were analyzed statistically using one-way analysis of variance (ANOVA), chi-squared with Bonferroni correction, and Kruskal-Wallis tests at a 0.05 significance level. Sixty-five percent of RDRs reported an interest in NCDTs as a discussion topic and almost half of them were positive towards their use, however, sixty percent of respondents were hesitant to diagnose caries solely using NCDTs. Fiber-optic-transillumination (FOTI) systems were ranked the best overall and with regard to all the investigated criteria (p < 0.05). Chosen reasons for FOTI included price followed by ease of use. In general, high price rated as the most perceived reason for not choosing a given NCDT followed by low practical applicability. Meanwhile, ease of use followed by relevant application ranked as the main reported reasons to choose an NCDTs.

Global caries experience in children and its relationship with government expenditures on education and health, sugar consumption, and years of schooling: An ecological study

OBJECTIVE

To evaluate the influence of gross domestic product (GDP), government expenditures on education and health (% of GDP), per capita sugar consumption, and years of schooling on caries experience (DMFT) in 12-year-old children globally.

METHODS

The study analyzed global data of GDP, sugar consumption, years of schooling, expenditure on education and health, and DMFT from 69 countries. Information about DMFT and sugar consumption was retrieved from the World Health Organization while data of other study variables were available from the United Nations Development Program. Data were compared among low, middle, and high-income countries.

RESULTS

Sugar consumption (p = 0.005) and years of schooling increased progressively from low-income to high-income countries (p < 0.001). The greater percentage of GDP was spent on health (6.55 ± 2.94) than on education (3.48 ± 2.60). Upper-middle-income countries had the highest mean DMFT score (2.23 ± 1.23) and per capita sugar consumption (33.28 ± 14.06). High-income countries spent 4.33% of their GDP on education followed by low-income countries (3.92%) (p = 0.037). Similar trends were observed with regards to the percentage of GDP spent on health (p = 0.003). Univariate analysis showed a significant negative correlation between the percentage of GDP spent on education (r = -0.252, p = 0.037) and DMFT. Significant correlation remained in multivariate analysis; the percentage of GDP spent on education and DMFT in children (B = -0.128, p = 0.028).

CONCLUSION

Low, middle, and high-income countries demonstrated significant inequalities regarding caries experience, sugar consumption, and share of GDP spent on health and education. Increasing the share of GDP on education may reduce caries burden in children globally.

Dental Sealant Composition-Retention Assessment in Young Permanent Molars

Tooth decay in children and adolescents remains a public health problem, despite prophylaxis and preventive measures being largely available. The aim of our study was to evaluate the clinical behavior of four dental sealants, related to first permanent molar topography and patient age (when sealant was applied for the first time). We assessed, by means of visual inspection and palpation with a dental probe, a group of 200 children, enrolled corresponding to school age-grade (mean age of 7 years at baseline) and randomly divided according to the material used as dental sealant (Admira seal©, Embrace Wet Bond©, Fotoseal©, GC Fuji Triaje©) in 4 groups (n = 50). Sealant clinical evaluation was made at 6-, 12-, 18-month intervals for dental material retention assessment. At 6 months, the sealant detached the most from 3.6 molars, and the material used was Fotoseal© (27.6%). At 12 months, Fotoseal© (48.3%) and GC Fuji Triaje© (41.4%) from 3.6 molars express detachment. At 18 months, 4.6. molars sealed with Admira Seal© (25.7%) and Embrace Wet Bond© (28.6%) lost the sealant. We noticed less detachment in maxillary molars and if sealant was applied around 7 years of age. In conclusion, sealant application on first permanent molars must be encouraged and practitioners can choose between various materials available.

The Antibacterial Effects of Resin-Based Dental Sealants: A Systematic Review of In Vitro Studies

This review aimed to assess the antimicrobial effects of different antibacterial agents/compounds incorporated in resin-based dental sealants. Four databases (PubMed, MEDLINE, Web of Science and Scopus) were searched. From the 8052 records retrieved, 275 records were considered eligible for full-text screening. Nineteen studies met the inclusion criteria. Data extraction and quality assessment was performed by two independent reviewers. Six of the nineteen included studies were judged to have low risk of bias, and the rest had medium risk of bias. Compounds and particles such as zinc, tin, Selenium, chitosan, chlorhexidine, fluoride and methyl methacrylate were found to be effective in reducing the colony-forming unit counts, producing inhibition zones, reducing the optical density, reducing the metabolic activities, reducing the lactic acid and polysaccharide production and neutralizing the pH when they are added to the resin-based dental sealants. In addition, some studies showed that the antibacterial effect was not significantly different after 2 weeks, 2 months and 6 months aging in distilled water or phosphate-buffered saline. In conclusion, studies have confirmed the effectiveness of adding antibacterial agents/compounds to dental sealants. However, we should consider that these results are based on laboratory studies with a high degree of heterogeneity.

Caries risk assessment in dental practices by dentists from a Brazilian community

Data on dental practices related to caries risk assessment (CRA) are scarce among Brazilian dentists. This study aimed to determine the prevalence of CRA use by dentists and factors associated with its use, as well as to quantify dentists' ratings of the importance of specific factors when treatment planning. Dentists registered at the Regional Council of Dentistry of São Paulo State - Araraquara region were sent two paper questionnaires that comprised: a) characteristics of dentists themselves, their practices, and their patients; and b) the translated version of the "Assessment of Caries Diagnosis and Caries Treatment" Questionnaire from the U.S. National Dental Practice-Based Research Network. Participants were 206 dentists who currently practiced in Araraquara and treated dental caries. Descriptive statistics and multiple logistic regression analyses were used for data analysis. Thirty-six percent of the dentists reported they perform CRA and, among them, 36% indicated they record the assessment on a special form that is kept in the patient chart. More years since dental school graduation (OR = 1.1, p = 0.002) and holding an advanced academic degree (OR=2.6, p=0.005) were associated with a higher likelihood of performing CRA, whereas exclusively using a private practice model (OR = 0.5, p = 0.016) was associated with a lower likelihood of performing CRA. The current oral hygiene and commitment to return for follow-up were the most important risk factors for treatment planning. In conclusion, CRA was not a routine procedure in daily practice among the majority of participating dentists. Specific demographic, practice and academic education characteristics were associated with performing CRA.

Knowledge and opinions of French dental students related to caries risk assessment and dental sealants (preventive and therapeutic)

OBJECTIVES

A national questionnaire study was performed to document knowledge and opinions of French dental students (FDSs) about minimal intervention (MI) in dentistry especially caries risk assessment (CRA) and dental sealants (DSs).

MATERIALS AND METHODS

A questionnaire was administered to the fifth-year dental FDSs (n = 1370) from the 16 French dental schools. Descriptive and statistical analyses were performed.

RESULTS

The response rate was 84.5%. A large majority of respondents (87.8%) linked MI with minimally invasive dentistry and 77.4% considered MI as a concept based on prevention. About 80% stated they use CRA in clinical practice, mostly without any specific form. If 80.4% of the respondents would base their treatment plans on CRA, only 55.1% would regularly plan preventive regimens according to individual risk level. However, while 96.6% declared they perform preventive DSs, only 44.3% considered therapeutic sealants as a routine treatment. Although 75.1% of FDSs stated that they had sufficient learning and training related to CRA, 55.9% thought that they need further education about preventive and therapeutic DSs.

CONCLUSION

Although FDSs seem to be aware of the importance of CRA and preventive strategies, this study shows the need to harmonize the teaching in cariology according to the latest European recommendations.

CLINICAL RELEVANCE

A national questionnaire study showed variability towards knowledge and opinions of FDSs related to MI in cariology. This may impact care provisions in their future professional life showing the urgent need to harmonize the teaching of MI in cariology in France.

METHODS FOR CARIES PREVENTION IN ADULTS AMONG DENTISTS FROM A BRAZILIAN COMMUNITY: Adult' caries prevention among Brazilian dentists

Little is known about dental practice patterns of caries prevention in adults among Brazilian dentists.

OBJECTIVE

To quantify procedures used for caries prevention for adult patients among dentists from a Brazilian community.

METHODS

Dentists (n=197) who reported that at least 10% of their patients are more than 18 years old participated in the first Brazilian study that used a translated version of the "Assessment of Caries Diagnosis and Caries Treatment" from the U.S. National Dental Practice-Based Research Network. A questionnaire about characteristics of their practice and patient population were also completed by the dentists. Generalized linear regression models and a hierarchal clustering procedure were used (p<0.05).

RESULTS

In-office fluoride application was the preventive method most often reported. The main predictors for recommending some preventive agent were: female dentist (dental sealant; in-office fluoride; non-prescription fluoride) and percentage of patients interested in caries prevention (dental sealant; in-office fluoride; non-prescription fluoride). Other predictors included private practice (dental sealant), percentage of patients 65 years or older (in-office fluoride), graduation from a private dental school (non-prescription fluoride), years since dental school graduation (chlorhexidine rinse) and using a preventive method (recommending sealant/fluoride/chlorhexidine rinse/sugarless, xylitol gum). Cluster analysis showed that dentists in the largest subgroup seldom used any of the preventive agents.

CONCLUSION

Dentists most often reported in-office fluoride as a method for caries prevention in adults. Some practitioner, practice and patients' characteristics were positively associated with more-frequent use of a preventive agent.

Nonrestorative Management of Cavitated and Noncavitated Caries Lesions

The objective of this article is to review evidence-based strategies available for the nonrestorative management of caries lesions, both cavitated and noncavitated. The goal is to help clinicians make appropriate decisions regarding nonrestorative management of caries lesions. In addition, in the decision-making process, clinicians must consider thresholds for restorative and nonrestorative care and strategies for nonrestorative management that are supported by best available evidence. It is important that this information be considered taking into account a provider's clinical expertise and a patient's treatment needs and preferences, in order to maintain health and preserve tooth structure.
