RESUMO

Adequate and transparent reporting is necessary for critically appraising research. Yet, evidence suggests that the design, conduct, analysis, interpretation, and reporting of oral health research could be greatly improved. Accordingly, the Task Force on Design and Analysis in Oral Health Research-statisticians and trialists from academia and industry-empaneled a group of authors to develop methodological and statistical reporting guidelines identifying the minimum information needed to document and evaluate observational studies and clinical trials in oral health: the Oral Health Statistics Guidelines. Drafts were circulated to the editors of 85 oral health journals and to task force members and sponsors and discussed at a December 2020 workshop attended by 49 researchers. The final version was subsequently approved by the task force in September 2021, submitted for journal review in 2022, and revised in 2023. The checklist consists of 48 guidelines: 5 for introductory information, 17 for methods, 13 for statistical analysis, 6 for results, and 7 for interpretation; 7 are specific to clinical trials. Each of these guidelines identifies relevant information, explains its importance, and often describes best practices. The checklist was published in multiple journals. The article was published simultaneously in JDR Clinical and Translational Research, the Journal of the American Dental Association, and the Journal of Oral and Maxillofacial Surgery. Completed checklists should accompany manuscripts submitted for publication to these and other oral health journals to help authors, journal editors, and reviewers verify that the manuscript provides the information necessary to adequately document and evaluate the research.

RESUMO

Adequate and transparent reporting is necessary for critically appraising published research. Yet, ample evidence suggests that the design, conduct, analysis, interpretation, and reporting of oral health research could be greatly improved. Accordingly, the Task Force on Design and Analysis in Oral Health Research-statisticians and trialists from academia and industry-identified the minimum information needed to report and evaluate observational studies and clinical trials in oral health: the Oral Health Statistical (OHStat) Guidelines. Drafts were circulated to the editors of 85 oral health journals and to Task Force members and sponsors and discussed at a December 2020 workshop attended by 49 researchers. The guidelines were subsequently revised by the Task Force's writing group. The guidelines draw heavily from the Consolidated Standards for Reporting Trials, Strengthening the Reporting of Observational Studies in Epidemiology (STROBE), and Consolidated Standards for Reporting Trials harms guidelines and incorporate the SAMPL guidelines for reporting statistics, the CLIP principles for documenting images, and the GRADE indicating the quality of evidence. The guidelines also recommend reporting estimates in clinically meaningful units using confidence intervals, rather than relying on P values. In addition, OHStat introduces 7 new guidelines that concern the text itself, such as checking the congruence between abstract and text, structuring the discussion, and listing conclusions to make them more specific. OHStat does not replace other reporting guidelines; it incorporates those most relevant to dental researches into a single document. Manuscripts using the OHStat guidelines will provide more information specific to oral health research.

RESUMO

STATEMENT OF PROBLEM: The design of porous tantalum trabecular metal-enhanced titanium (TM) dental implants promises improved osseointegration, especially when grafting materials such as demineralized bone matrix are used; however, studies are lacking. PURPOSE: The purpose of this retrospective study was to compare TM implants with conventional titanium alloy (Ti) implants with and without demineralized bone matrix in terms of peri-implant bone remodeling in the first year after implant loading. MATERIAL AND METHODS: A chart review was used for all patients receiving Tapered Screw-Vent Ti and TM implants. Implants were placed and restored by a single provider between 2011 and 2015. Peri-implant bone remodeling was compared by using a paired t test (α=.05). RESULTS: A total of 82 patients received 205 implants, 44 TM and 161 Ti implants (control). No implants failed in the TM group (survival rate of 100%), and 3 implants in total, 1 immediate, failed in the Ti groups (survival rate of 98.1%). TM implants exhibited a 0.28-mm bone gain on average, whereas the control group demonstrated 0.20 mm of marginal bone loss after the first year of implant loading. Multivariate logistic regression analysis demonstrated that the odds of having bone loss was 64% less (odds ratio: 0.36; 95% confidence interval: 0.14-0.94) in the TM group than in the Ti group after controlling for bone grafting, implant location, immediate placement, bone type, and pretreatment bone level. CONCLUSIONS: TM implants exhibited less peri-implant bone loss than the control Ti implants.

RESUMO

This study examined pediatric dentists' perspectives on the types of dental services general dentists provide to children who are 0-3 years old. A web-based survey was sent to 5185 pediatric dentists and 769 (14.8%) responded. Among the respondents, 58% agreed with general dentists' providing an age 1 dental visit. Only 24% agreed with general dentists' performing complex behavior management techniques, such as sedation, to patients aged 0-3 years. Those respondents who taught pediatric dentistry full time were more likely to agree with general dentists' providing an age 1 dental visit (P = 0.0088). Those who reported that their own dental school had adequately prepared them for this type of age 1 visit were also more in agreement (P < 0.0001). The results of this study promote better understanding of pediatric dentists' perceptions of the level of collaboration between general dentists and pediatric dentists; the types of oral health services general dentists can provide for children aged 0-3 years; and the anticipated level of competency of entry-level general dentists.

RESUMO

OBJECTIVES: To evaluate the concordance between clinical practice and published evidence by dental faculty and graduating students of the Virginia Commonwealth University School of Dentistry. METHODS: A questionnaire previously developed by the National Dental Practice-Based Research Network with 12 clinical scenarios was administered to VCU faculty and graduating students. Responses were scored as either consistent or inconsistent with published evidence and then analyzed for differences between dental faculty, graduating students, and the national results. RESULTS: There were 43 dental faculty members with at least half-time student contact who responded to the survey. Faculty concordance ranged from 33% to 100%, and general practice faculty had the highest concordance (82%). Eighty-five of the graduating class of 98 responded to the survey, and student concordance ranged from 18% to 92% and averaged 67%. General practice faculty had higher concordance with published evidence than recently graduated dental students. CONCLUSIONS: Graduating students and dental faculty demonstrated higher concordance with evidence-based practice than practitioners in the National Dental Practice-Based Research Network. General practice dental faculty demonstrated adequate concordance, but students demonstrated only a medium-level concordance. Practitioners involved in teaching dental students are better able to keep up with evolving evidence and are better able to demonstrate evidence-based practice.

RESUMO

Dietary supplement effects and drug interactions can lead to significant adverse health events, thus potentially impacting the safe delivery of oral healthcare. This study sought to determine the frequency of, and factors impacting, dietary supplement use among 209 dental patients and whether the design of a medical history questionnaire influences reporting of supplement use. Patients were randomly allocated to 1 of 2 groups in which they completed either a standard medical history questionnaire (n = 107) or the same questionnaire with an additional item about dietary supplement use (n = 102). All patients were then administered a survey with questions about their demographics, their use and knowledge of dietary supplements, and the person or persons who recommended dietary supplement use to the patient. While 62% of the total population (130/209) reported supplement use, specific prompting nearly doubled the number of supplements reported (mean with prompting: 1.53; mean without prompting: 0.76; P < 0.0001). Patients younger than 30 years of age reported significantly less dietary supplement use than all other age groups except the 30-40 age group (P = 0.0003). An estimated 70% of all respondents were not aware of potentially detrimental side effects of dietary supplement use or possible interactions with conventional drug therapies. Since patients tended to report a greater use of dietary supplements when specifically asked about their use on a medical history questionnaire, a checklist or set of designated questions may be a suitable first step toward gathering this essential information.

RESUMO

PURPOSE: Although various prophylactic systemic antibiotic regimens have been suggested to minimize failure after dental implant placement, the role of antibiotics in implant dentistry is still controversial. The purpose of the present survey was to determine the current antibiotic prescribing habits of oral and maxillofacial surgeons in conjunction with routine dental implant placement to determine whether any consensus has been reached among such practitioners. MATERIALS AND METHODS: An electronic survey was sent by electronic mail to all members of the American College of Oral and Maxillofacial Surgeons. The questions asked were related to whether antibiotics were routinely prescribed either pre- or postoperatively during routine dental implant placement, and, if so, what antibiotics, dosage, frequency, and duration were used. The survey participants were also asked to specify whether they were in solo private practice, group private practice, academia, military, or "other." The results were tabulated and analyzed using SAS software. Descriptive statistics and χ(2) analyses were used. RESULTS: A total of 217 members responded to the survey. Overall, 112 of 217 (51.6%) prescribed antibiotics preoperatively (95% confidence interval [CI] 50.0 to 58.2%) and 152 of 213 (71.4%) prescribed antibiotics postoperatively (95% CI 65.0 to 77.0%) during routine dental implant placement. Also, 72 (34%) indicated that they prescribed antibiotics both pre- and postoperatively. The most common preoperative regimen used was amoxicillin 2 g given 1 hour before the procedure (32%, n = 36). The most common postoperative regimen used was amoxicillin 500 mg 3 times daily for 5 days (53%, n = 81). CONCLUSIONS: We found no consensus among oral and maxillofacial surgeons regarding the use of antibiotics in association with routine dental implant placement, the type of regimen to use, or whether such use is even effective in preventing early implant loss. Furthermore, most of the antibiotic regimens being used are not in accordance with the recommendations current in the published data.

RESUMO

INTRODUCTION: A new, highly filled primer is currently marketed as a fluoride delivery system effective in reducing white spot lesions in orthodontic patients. However, no studies in the literature support this claim. The purpose of this in-vivo study was to investigate the retention and the efficacy of this primer in reducing the formation of white spot lesions. METHODS: In each patient for whom premolar extractions were planned (n = 22), 1 premolar was randomly chosen as the experimental tooth for the application of the fluoride delivery system (Opal Seal; Ultradent Products, South Jordan, Utah), and the contralateral tooth was assigned as the control to receive the standard treatment (Transbond XT; 3M Unitek, Monrovia, Calif). After the bonding procedures, separators were placed around the premolar brackets to encourage plaque retention over 8 weeks. After the extractions, the tooth surfaces were evaluated visually and with microhardness techniques for demineralization. Primer retention was also investigated. RESULTS: There were no statistically significant differences in the numbers of white spot lesions between the 2 groups. The primer retention was calculated as 50%. CONCLUSIONS: The results indicated no significant difference between the efficacies of the fluoride-releasing primer and the control primer in reducing demineralization over the duration of the study.

RESUMO

An interprofessional educational approach was used to provide five in-service training sessions for all direct health care providers in a long-term care facility, and one half-day seminar/live webinar for community-licensed health care professionals. Content included presentations by five disciplines: (a) periodontist: oral-systemic relationship, (b) oral pathologist: oral pathology, (c) pharmacist: oral health-pharmacological link, (d) dietitian: oral health-dietary link, and (e) occupational therapist: providing and practicing proper oral hygiene. Significant improvement in posttest scores for the five in-service training sessions and the half-day seminar/live webinar was revealed in t-test results, representing an increase in knowledge gained. Approximately 80% of the 145 participants indicated that they would make a change in patient care. Findings indicate that the in-service training sessions and half-day seminar/live webinar supported development of the geriatric work force by utilizing an interprofessional educational approach which will assist in meeting the oral health care needs of the geriatric population.

RESUMO

BACKGROUND: Considering evidence of closing the gender gap in dental scholarship, this study assessed women's participation as authors, reviewers, and members of the editorial board for The Journal of the American Dental Association (JADA) from 2000 through 2022. METHODS: The study authors downloaded author names from PubMed and retrieved names of reviewers and editorial board members from JADA's pages. The authors used Gender-API software to determine gender on the basis of first names. They used logistic regression to test for trends. RESULTS: From January 2000 through December 2022, there were 2,935 full-length articles, 2,775 reviewers, 4 editors in chief, and 85 editorial board members. The percentage of women authors increased by 1.2% annually (95% CI, 1.03% to 1.33%), reaching 47% in 2022. First authorship increased by 2.1% annually (95% CI, 1.84% to 2.39%) and has been at more than 50% since 2016. In articles with multiple authors, there was a modest increase; second authorship increased 0.7% annually (95% CI, 0.36% to 1.09%) and last authorship by 0.7% (95% CI, 0.03% to 1.00%). Women reviewers increased 0.8% annually (95% CI, 0.68% to 0.97%), but the percentage of women on the editorial board did not increase significantly and was 41% in 2022. CONCLUSIONS: It was anticipated that 50% of JADA authors would be women by 2024. However, women are still underrepresented on the editorial board. A comprehensive effort is needed to foster role models, provide mentorship opportunities for women, and support women's professional advancement in dental research and publications. PRACTICAL IMPLICATIONS: Gender-based disparities affect women in dental education and clinical practice. Serving as an editorial board member, reviewer, or author can affect academic promotion and the type of scientific investigation being conducted and indirectly affects women's health outcomes.

RESUMO

OBJECTIVES: In systemic lupus erythematosus (SLE) patients, glomerular filtration rate (GFR) is usually estimated using the modified Cockcroft-Gault (mCG) and Modification of Diet in Renal Disease (MDRD) equations. We aimed to study cystatin C (sCysC) in SLE to assess its agreement with standard renal indices and investigate factors affecting sCysC in SLE. METHODS: SLE patients (≥4 ACR criteria) and healthy women from Greater Manchester were recruited and clinical assessments were undertaken. SCysC was measured using R & D Systems' ELISA. Agreement between renal measures was assessed using Deming plots and factors associated with sCysC in SLE were examined by multiple linear regression analyses. RESULTS: 178 patients and 68 controls had median (IQR) ages of 53 (46-61) and 50 (39-60) years, respectively. In an age-adjusted analysis, SLE patients had higher sCysC (1.16 [0.98-1.36] vs. 0.950 [0.73-1.13] mg/l; p<0.0001) and within SLE those with a history of lupus nephritis had higher sCysC (1.31 [1.10-1.66] vs. 1.11 [0.95-1.29] mg/l; p<0.005). SCysC correlated positively with serum creatinine, and inversely to renal measures (r=-0.530; p<0.0001 [mCG], and r=-0.620; p<0.0001 [MDRD]). There was closer agreement between the two eGFR measures than between either eGFR measures and sCysC. In addition to age and serum creatinine, a multivariate analysis (ß, p) found that high-sensitivity C-reactive protein (hs-CRP) (0.03, 0.026) was also independently associated with sCysC in SLE. CONCLUSIONS: In SLE, sCysC may be influenced by low grade inflammation as well as by renal dysfunction. Therefore, SCysC should not supplant current assessment of renal dysfunction in SLE.

RESUMO

Children with incarcerated parents are at risk for a variety of problematic outcomes, yet research has rarely examined protective factors or resilience processes that might mitigate such risk in this population. In this volume, we present findings from five new studies that focus on child- or family-level resilience processes in children with parents currently or recently incarcerated in jail or prison. In the first study, empathic responding is examined as a protective factor against aggressive peer relations for 210 elementary school age children of incarcerated parents. The second study further examines socially aggressive behaviors with peers, with a focus on teasing and bullying, in a sample of 61 children of incarcerated mothers. Emotion regulation is examined as a possible protective factor. The third study contrasts children's placement with maternal grandmothers versus other caregivers in a sample of 138 mothers incarcerated in a medium security state prison. The relation between a history of positive attachments between mothers and grandmothers and the current cocaregiving alliance are of particular interest. The fourth study examines coparenting communication in depth on the basis of observations of 13 families with young children whose mothers were recently released from jail. Finally, in the fifth study, the proximal impacts of a parent management training intervention on individual functioning and family relationships are investigated in a diverse sample of 359 imprisoned mothers and fathers. Taken together, these studies further our understanding of resilience processes in children of incarcerated parents and their families and set the groundwork for further research on child development and family resilience within the context of parental involvement in the criminal justice system.

RESUMO

PURPOSE: The purpose of this study was to evaluate residents' understanding of biostatistics and interpretation of research results. MATERIALS AND METHODS: A questionnaire previously used in internal medicine residents was modified to include oral and maxillofacial surgery (OMS) examples. The survey included sections to identify demographic and educational characteristics of residents, attitudes and confidence, and the primary outcome-knowledge of biostatistics. In 2009 an invitation to the Internet survey was sent to all 106 program directors in the United States, who were requested to forward it to their residents. RESULTS: One hundred twelve residents responded. The percentage of residents who had taken a course in epidemiology was 53%; biostatistics, 49%; and evidence-based dentistry, 65%. Conversely, 10% of OMS residents had taken none of these classes. Across the 6-item test of knowledge of statistical methods, the mean percentage of correct answers was 38% (SD, 22%). Nearly half of the residents (42%) could not correctly identify continuous, ordinal, or nominal variables. Only 21% correctly identified a case-control study, but 79% correctly identified that the purpose of blinding was to reduce bias. Only 46% correctly interpreted a clinically unimportant and statistically nonsignificant result. None of the demographic or experience factors of OMS residents were related to statistical knowledge. Overall, OMS resident knowledge was below that of internal medicine residents (P<.0001). However, OMS residents were overconfident in their claim to understand most statistical terms. CONCLUSIONS: OMS residents lack knowledge in biostatistics and the interpretation of research and are thus unprepared to interpret the results of published clinical research. Residency programs should include effective biostatistical training in their curricula to prepare residents in evidence-based dentistry.

RESUMO

The intrinsic acidity of chalcocyclopentadienes (CpXH; X=O, S, Se, Te) is investigated by high-level G3B3 and G2 ab initio as well as B3LYP DFT calculations, which show that, independent of the nature of the heteroatom, all chalcocyclopentadienes are stronger acids in the gas phase than cyclopentadiene. However the acidity does not increase regularly down the group, and the acidity enhancement for Te derivatives is five times larger than for O derivatives, but only twice that of S-containing compounds. The most favorable deprotonation process corresponds to loss of the proton attached to the heteroatom, with the sole exception of the 5-substituted 1,3-cyclopentadienes, for which the O and S derivatives are predicted to behave as carbon acids. No matter the nature of the heteroatom, the 1-substituted 1,3-cyclopentadienes are the strongest acids. The intrinsic acidity of all isomers, namely, 1-substituted, 2-substituted, and 5-substituted 1,3-cyclopentadienes, increases with increasing aromaticity of the anion formed on deprotonation, and therefore the Te compound is the strongest acid for the three series. However, the intrinsic acidity of chalcocyclopentadienes is not dictated by aromaticity, so that, in general, the most stable deprotonated species do not coincide with the most aromatic ones.

RESUMO

INTRODUCTION: Despite the many advances to improve the practice of orthodontics, white spot lesions, or decalcifications, remain a common complication in patients with poor oral hygiene. The purpose of this study was to assess the perceptions and level of awareness of patients, parents, orthodontists, and general dentists toward the development of white spot lesions during orthodontic treatment. METHODS: This was a prospective epidemiologic survey of the perceptions of orthodontic patients (n = 315), parents (n = 279), orthodontists (n = 305), and general dentists (n = 191) regarding the significance, prevention, and treatment of white spot lesions. RESULTS: All surveyed groups indicated that white spot lesions detracted from the overall appearance of straight teeth, attributed primary responsibility for the prevention of white spot lesions to the patients themselves, and thought that the general dentist should be responsible for treating white spot lesions. Patients regarded themselves as ultimately responsible for the prevention of white spot lesions (P <0.05). CONCLUSIONS: The patients, parents, orthodontists, and general dentists had similar perceptions regarding the significance, prevention, and treatment of white spot lesions. All groups indicated that patients were the most responsible for the prevention of white spot lesions. Communication among patients, parents, orthodontists, and general dentists needs to improve to decrease the incidence of white spot lesions in the orthodontic population.

RESUMO

Background: Armenia has trained physicians to practice family medicine (FM) for over 20 years. The pediatric population comprises a significant proportion of patients seen by FM practices, yet to date, there have been no studies assessing the knowledge and self-efficacy of FM physicians regarding pediatric care. As the first step is needs assessment to improve the quality of care, this study aims to assess the self-efficacy and knowledge of FM physicians regarding the care of pediatric patients. Materials and Methods: We distributed a survey to attendees at an FM conference in Lori Province, Armenia. The survey instrument assessed demographics and experience, self-efficacy in providing pediatric care, and pediatric knowledge via questions adapted from the American Board of Family Medicine (ABFM). Results: Eighty-seven percent of participants were female. Roughly half (45%) had trained through an FM residency program, while the remainder had retrained to become FM physicians following a residency in another field. Almost all (97%) practiced outside of the capital city, Yerevan. About half believed that their didactic (51%) and clinical education (48%) prepared them either "extremely" or "very" well. Overall, there was no clear relationship between participants' reported self-efficacy in a given area of pediatrics and their score in that area on the knowledge portion of the survey. Conclusions: Our findings reveal opportunities for improvement in knowledge related to pediatric care in FM physicians in Armenia, as well as a lack of relationship between reported self-efficacy and knowledge. Thus, future programs should not rely solely on self-reported gaps to identify or prioritize areas of focus. Further study is recommended in other specialties in Armenia and internationally to improve future programs.

RESUMO

To navigate towards a food source, animals frequently combine odor cues about source identity with wind direction cues about source location. Where and how these two cues are integrated to support navigation is unclear. Here we describe a pathway to the Drosophila fan-shaped body that encodes attractive odor and promotes upwind navigation. We show that neurons throughout this pathway encode odor, but not wind direction. Using connectomics, we identify fan-shaped body local neurons called h∆C that receive input from this odor pathway and a previously described wind pathway. We show that h∆C neurons exhibit odor-gated, wind direction-tuned activity, that sparse activation of h∆C neurons promotes navigation in a reproducible direction, and that h∆C activity is required for persistent upwind orientation during odor. Based on connectome data, we develop a computational model showing how h∆C activity can promote navigation towards a goal such as an upwind odor source. Our results suggest that odor and wind cues are processed by separate pathways and integrated within the fan-shaped body to support goal-directed navigation.
