Partial-mouth periodontal examination protocol for estimating periodontitis extent and severity in a US population.

We have previously demonstrated that half-mouth four-site periodontal examination protocol performed well in estimating periodontitis prevalence. This study aimed to assess biases associated with this same protocol in estimating periodontitis extent and severity in a United States population. Periodontitis extent as determined by percentage of sites with clinical attachment loss (CAL) ≥3, and ≥5 mm and severity as determined by mean CAL were calculated for full-mouth examination and half-mouth four-site protocol based on 3734 adults sampled from the National Health and Nutrition Examination Survey 2009-2010. Probing depth was excluded because of low data reliability. The comparison between full-mouth and half-mouth assessments was based on bias, relative bias, Wilcoxon signed-rank test, and intra-class correlation coefficient (ICC). For full-mouth examination, periodontitis extent was 21.2% for CAL ≥3 mm and 6.9% for CAL ≥5 mm; periodontitis severity (mean CAL) was 1.73 mm. Half-mouth four-site protocol provided bias -1.2% and relative bias -5.7% for extent (CAL ≥3 mm). Corresponding numbers were -0.3% and 4.3% for extent (CAL ≥5 mm), -0.05 mm and -2.9% for severity. Although the difference between full-mouth and half-mouth assessments was statistically significant, ICCs between them were ≥0.96 for extent (CAL ≥3, 5 mm), and severity (mean CAL). Half-mouth four-site protocol performed well in estimating periodontitis extent and severity based on CAL. Therefore, this protocol should be considered for periodontitis surveillance.

Assessment of partial-mouth periodontal examination protocols for periodontitis surveillance.

OBJECTIVE: To evaluate bias associated with nine identified partial-mouth periodontal examination (PMPE) protocols in estimating periodontitis prevalence using the periodontitis case definition given by the Centers of Disease Control and Prevention and American Academy of Periodontology (CDC/AAP). MATERIAL AND METHODS: Prevalence from full-mouth examination was determined in a sample of 3667 adults ≥30 years old from the National Health and Nutrition Examination Survey (NHANES) 2009-2010. Prevalence, absolute bias, relative bias, sensitivity and inflation factor were derived for these protocols according to the CDC/AAP definition and half-reduced CDC/AAP definition as ≤50% of sites were measured. RESULTS: Bias in moderate and severe periodontitis prevalence ranged between 11.1-52.5% and 27.1-76.3% for full-mouth mesiobuccal-distolingual protocol and half-mouth mesiobuccal protocol respectively; according to the CDC/AAP definition. With half-reduced CDC/AAP definition, half-mouth four sites protocol provided small absolute bias (3.2%) and relative bias (9.3%) for the estimates of moderate periodontitis prevalence; corresponding biases for severe periodontitis were -1.2% and -10.2%. CONCLUSION: Periodontitis prevalence can be estimated with limited bias when a half-mouth four sites protocol and a half-reduced CDC/AAP case definition are used in combination.

Assessing periodontitis in populations: a systematic review of the validity of partial-mouth examination protocols.

OBJECTIVE: To estimate bias associated with partial-mouth periodontal examination (PMPE) protocols regarding estimates of prevalence, severity and extent of clinical attachment loss (CAL), pocket depth (PD) and gingival recession (REC). MATERIAL AND METHODS: A search was made for articles published in English, from 1946 to 2012, which compared PMPE versus full-mouth periodontal examination protocols for CAL or PD ≥ 4 mm or REC ≥3 mm thresholds. PMPE protocols were evaluated for sensitivity of estimates of periodontitis prevalence, relative biases for severity and extent estimates. RESULTS: A review of the literature identified 12 studies which reported 32 PMPE protocols. Three PMPE protocols which had sensitivities ≥85% and relative biases ≤0.05 in absolute values for severity and extent estimates were as follows: (1) half-mouth six-sites, (2) diagonal quadrants six-sites and (3) full-mouth mesiobuccal-midbuccal-distobuccal (MB-B-DB). Two other PMPE protocols (full-mouth and half-mouth mesiobuccal-midbuccal-distolingual) performed well for prevalence and severity of periodontitis; however, their performance in estimates of extent was unknown. CONCLUSIONS: Among the 32 PMPE protocols listed, the half-mouth six-sites and full-mouth MB-B-DB protocols had the highest sensitivities for prevalence estimates and lowest relative biases for severity and extent estimates.

The journey beyond silos. Teaching and learning interprofessional ethics at UTHealth.

Interprofessional education and ethics education are two educational programs that blend together well, and, moreover, they are a natural fit for teaching in an academic health science center. The purpose of this paper is to describe our recent journey of developing and implementing an interprofessional ethics curriculum across the six schools of UTHealth. We provide an overview of the goals of the Campus-wide Ethics Program, which is housed in the McGovern Center for Humanities and Ethics, and we highlight certain innovative developments that are the result of the collaborative work of faculty and administrators from all six schools of UTHealth. In addition, a brief synopsis of the specific didactic and clinical courses in which ethics is a significant component is outlined for both the dental and the dental hygiene curricula. Lastly, we describe some of the recent scholarly activities that are a product of this new program. We are excited about our evolving efforts and the potential benefits of weaving interprofessional ethics within our school and across our campus. This article tells the story of our journey beyond "the silos" that are common among academic health science centers.

Teaching evidence-based practice at the University of Texas Dental Branch at Houston.

This brief report outlines the current curriculum for evidence-based practice at The University of Texas Dental Branch at Houston (UTDB). This curriculum is now based on the American Dental Association's Commission on Dental Accreditation 2010 Accreditation Standards for Dental Education Programs. Evidence-based practice is introduced to students in the first-year curriculum. Students learn to be clinically effective through use of the components of evidence-based practice, information search and retrieval, critical thinking (appraisal), and through information resource evaluation and then application to the patient or population. Planned innovations in curriculum include further implementation of evidence-based decision-making in clinical courses, including development of the clinical prescription as a means of demonstrating competence in asking and answering clinical questions, and of the portfolio as a means of demonstrating overall competence.

Conflicts of interest in research: is clinical decision-making compromised? An opinion paper.

Lack of transparency in funded research can compromise clinical decision-making in an evidence-based practice. Transparency can be defined as full disclosure of all financial assistance and support to authors and investigators. There is a perception that ethical principles are eroding and that research data can be biased due to conflicts of interest. These research outcomes biased or not, are used for clinical decision-making in the evidence-based practice. One suggested solution to this common ethical dilemma is to continue the dialogue on transparency in research and to create oversight bodies which include representatives from business and industry, private practice, academia, and research. There is increasing evidence of the need for more ethics education at all levels.

Development of an interdisciplinary course in information resources and evidence-based dentistry.

The capacity to locate, access, and appraise information is an important skill required for success in dental school and beyond. An interdisciplinary course was implemented to teach first-year dental students at the University of Texas Health Science Center at Houston Dental Branch about evidence-based dentistry, search strategies, critical appraisal of the literature, and dental informatics. Students learned to develop a clinical question, conduct a search to find answers to that question, and critically appraise one of the retrieved resources. Over a period of four years, a total of 259 dental students completed a questionnaire that requested their assessment of this course. Seventy-five percent of the respondents agreed or strongly agreed that they learned to effectively search databases such as the Cochrane Collaboration and PubMed and to critically appraise websites and journal articles and that the information on evidence-based dentistry and critical thinking skills was valuable. In response to open-ended questions, approximately 35 percent of the respondents mentioned the importance of learning to search PubMed and Cochrane databases. Approximately 20 percent of the respondents felt the course did not contain new information. These results indicated the effectiveness of the course in familiarizing the students with the capacity of online resources to help them locate, access, and appraise information pertinent to oral health issues and the practice of dentistry. A future goal is to integrate information and skills associated with evidence-based practice into other courses in the dental curriculum.

Stainless steel crowns versus amalgams in the primary dentition and decision-making in clinical practice.

This article reviews scientific dental literature related to amalgam restorations versus stainless steel crowns (SSCs) in the primary dentition. An extensive literature search of clinical studies was conducted to address the use of amalgams and SSCs in the primary dentition. The scientific literature provides evidence that SSCs demonstrate greater longevity and reduced need for retreatment, compared to multi-surface amalgam restorations. There is high-level evidence for the use of SSCs because of their cost-effectiveness, ease of placement, and longevity.

Methods of dental instrument processing, sterilization, and storage--a review.

A comprehensive instrument processing and sterilization program in the dental office is essential to ensure that the DHCP and the public are protected from disease transmission due to contaminated instruments/ devices. The Centers for Disease Control and Prevention and other organizations have made recommendations to help dental personnel with this aspect of patient care. By following the CDC's latest guidelines, the DHCP can develop an optimal program of dental instrument processing, sterilization and storage.

Dental practice implications of prion diseases.

This review article discusses dental practice implications of prion diseases, including Creutzfeldt-Jakob disease. The current universal precautions used for infection control in dentistry do not inactivate infectious prions. There is a theoretical, yet real risk of prion disease transmission through dental treatment, although the magnitude of that risk has not yet been determined. Medical, family, and travel histories can demonstrate the need for implementing improved levels of infection control. Best practices include the following: For certain cases, single-use disposable dental instruments should be used. Those instruments that are not disposable, should have a thorough physical cleaning, be soaked in hot 1N sodium hydroxide solution for 1 hour, and then autoclaved in a vacuum or porous-load autoclave at 134 degrees C to 138 degrees C for 18 to 20 minutes. Dental and other health care professionals need to understand prion diseases, and for best practice, consider implementing recommended changes to infection-control measures, since current practices do not destroy infectious prions.
