Periodontal regeneration risk assessment in the treatment of intrabony defects.

BACKGROUND: Regenerative approaches performed in periodontics seems to be efficient in treating intrabony defects. There are, however, many factors that may affect the predictability of the regenerative procedures. The present article aimed to propose a new risk assessment tool for treating periodontal intrabony defects by regenerative therapy. METHODS: Different variables that could affect the success of a regenerative procedure were considered based on their impact on (i) the wound healing potential, promoting wound stability, cells, and angiogenesis, or (ii) the ability to clean the root surface and maintain an optimal plaque control or (iii) aesthetics (risk for gingival recession). RESULTS: The risk assessment variables were divided into a patient, tooth, defect, and operator level. Patient-related factors included medical conditions such as diabetes, smoking habit, plaque control, compliance with supportive care, and expectations. Tooth-related factors included prognosis, traumatic occlusal forces or mobility, endodontic status, root surface topography, soft tissue anatomy, and gingival phenotype. Defect-associated factors included local anatomy (number of residual bone walls, width, and depth), furcation involvement, cleansability, and number of sides of the root involved. Operator-related factors should not be neglected and included the clinician's level of experience, the presence of environmental stress factors, and the use of checklists in the daily routine. CONCLUSIONS: Using a risk assessment comprised of patient-, tooth-, defect- and operator-level factors can aid the clinician in identifying challenging characteristics and in the treatment decision process.

Increasing the margin of patient safety for periodontal and implant treatments: The role of human factors.

Early complications following periodontal and dental implant surgeries are typically attributed to technique or poor biological response, ignoring the possibility of the human element. Interestingly, significant experience is not correlated with increased success, whereas evidence supports the impact of clinical behavior on patient outcome. This is the result of errors, much like those scrutinized in other high-risk technical fields, such as aviation. What can be surprising is that those who make these errors are very well acquainted with best practices. Given this, how is it possible for the conscientious practitioner to fail to apply protocols that are nonetheless very well known? Recently, the concepts of human and organizational factors have been translated to medicine, though dentistry has been slow to recognize their potential benefit. This review lists specific human factor behaviors, such as use of checklists and crew resource management, which might improve postsurgical outcome.

Data Collection for Adverse Events Reporting by US Dental Schools.

OBJECTIVES: Accreditation of US dental schools requires a formal system of quality assessment of clinical adverse events (AE). There is no universal system to collect, record, interpret, or release findings or trends pertaining to AEs. The objective of this study was to compare similarities and differences among the AE reporting forms used at US dental schools. METHODS: Sixteen (24%) dental schools responded to a query to provide copies of their AE forms. The forms were analyzed to identify unique AE items. A total of 69 unique AE items were identified, grouped, and ranked according to frequency. Methods of AE data collection were also noted. RESULTS: The forms were different in organization, form, and content. The 69 AE items represented a wide variety of information, with no standardization of the type of information, how it was collected, or by whom. We identified 9 most requested AE items and 4 least requested AE items. The schools differed in how the information was obtained: 2 schools used a menu, 8 schools used free response, and 6 schools used a hybrid of both methods. CONCLUSIONS: We found that dental school clinic AE reporting forms are not standardized in structure, organization, or content. We conclude that a hybrid form containing both guided responses and free responses would ensure that proper information is being reported to fully understand why/how an AE occurred. In addition, dental schools need to develop a standardized method of collecting and assessing AE data which will allow for quality improvement and increased patient safety.

Psychiatry and Fitness to Fly After Germanwings.

In March 2015, a co-pilot flying Germanwings Flight 9525 deliberately pointed his airplane into a descent, killing himself, five other crew members, and 144 passengers. Subsequent investigation and review teams examined the incident and considered potential lessons to maximize air safety. In this article, aviation industry clinical leaders, including the U.S. Federal Air Surgeon and Chief Psychiatrist from the Federal Aviation Administration (FAA), along with a professional pilot and collaborating forensic psychiatrists, discuss suicide-by-plane, evolving themes related to public safety responsibilities for psychiatrists treating pilots, and forensic trends in pilot evaluation for medical certification from an aerospace psychiatric perspective. We explore how psychiatric aspects of pilot fitness and aviation safety are examined across perspectives, including unsafe acts, preconditions, organizational factors, and unsafe supervision. We explore practices for civilian pilots and offer information related to military pilot fitness. Lessons from Germanwings are presented, as is the need for increased support for pilots who might be concerned about revealing mental health challenges for fear of loss of medical certification and pilot employment. The Air Line Pilots Association Pilot Assistance Network is highlighted as one example of pilots supporting pilots to increase airway safety.

Simulation-Based Medical Emergencies Education for Dental Students: A Three-Year Evaluation.

This aim of this study was to develop and evaluate a simulation program for dental students to supplement a lecture-based medical emergencies course. Students' self-reported knowledge, experience, confidence, and ability regarding medical emergencies were assessed as program outcomes. For three years (in 2014, 2015, and 2016), all second-year students (N=333) at one U.S. dental school were randomly assigned to groups of 15 and participated in 15 simulated clinical scenarios. All students completed a 21-item pre-post survey and rated their knowledge, experience, and confidence using simulated emergencies. Following the intervention, students' ability to complete critical actions was also peer-assessed using a ten-item checklist. Four open-ended questions were included on the post-intervention survey for acquisition of additional data. For all years, students' self-reported measurements significantly improved with high practical impact (p≤0.001, g=|0.62, 3.93|), with the exception of calling 911 (knowledge). Peer-rated performance indicated the students were deficient (<75% success) in the following: inhaler use, dose of local anesthetic, dose of epinephrine, and EpiPen use. Content analysis of students' comments pointed to areas that need improvement but found high satisfaction with the program. These findings indicate that this program improved students' knowledge, experience, and confidence using simulated medical emergencies.

An approach to value-based simulator selection: The creation and evaluation of the simulator value index tool.

BACKGROUND: Currently there is no reliable, standardized mechanism to support health care professionals during the evaluation of and procurement processes for simulators. A tool founded on best practices could facilitate simulator purchase processes. METHODS: In a 3-phase process, we identified top factors considered during the simulator purchase process through expert consensus (n = 127), created the Simulator Value Index (SVI) tool, evaluated targeted validity evidence, and evaluated the practical value of this SVI. A web-based survey was sent to simulation professionals. Participants (n = 79) used the SVI and provided feedback. We evaluated the practical value of 4 tool variations by calculating their sensitivity to predict a preferred simulator. RESULTS: Seventeen top factors were identified and ranked. The top 2 were technical stability/reliability of the simulator and customer service, with no practical differences in rank across institution or stakeholder role. Full SVI variations predicted successfully the preferred simulator with good (87%) sensitivity, whereas the sensitivity of variations in cost and customer service and cost and technical stability decreased (≤54%). The majority (73%) of participants agreed that the SVI was helpful at guiding simulator purchase decisions, and 88% agreed the SVI tool would help facilitate discussion with peers and leadership. CONCLUSION: Our findings indicate the SVI supports the process of simulator purchase using a standardized framework. Sensitivity of the tool improved when factors extend beyond traditionally targeted factors. We propose the tool will facilitate discussion amongst simulation professionals dealing with simulation, provide essential information for finance and procurement professionals, and improve the long-term value of simulation solutions. Limitations and application of the tool are discussed.

Adaptation of airline crew resource management principles to dentistry.

BACKGROUND: The aviation industry uses crew resource management (CRM) to address the human aspect of error. Dentistry can incorporate these concepts to reduce dental error. The authors provide a checklist to help clinicians mitigate error. METHODS: Health care systems have begun to focus on medical error. During the past 30 years, the airline industry has developed mitigation strategies that are being adapted for medicine. CRM involves the use of information, equipment and people to increase safety by targeting early identification of errors. RESULTS: To enhance safety, practitioners must implement forward-thinking strategies. Because human error is inevitable, threat and error management (TEM) techniques are needed to help identify and trap error before it develops into unexpected outcomes. Risk analysis increases situational awareness (SA) of potential dental error. Efficiency increases with early error detection. CONCLUSIONS: The authors provide a dental checklist that is divided into "appointment review," "before procedure," "procedure," "before dismissal" and "after dismissal" to organize dental activities in a manner that enhances error detection. PRACTICE IMPLICATIONS: The dental checklist is a tool to incorporate CRM and TEM techniques into the dental care environment to increase SA, safety and efficiency.

Ability of dental students to deliver oxygen in a medical emergency.

This study was conducted to evaluate the ability of dental students to administer emergency oxygen to a patient during a simulated emergency. Forty third-year (D3) and fourth-year (D4) dental students were recruited and asked to demonstrate their ability in managing a simulated angina attack. Students were tested on their knowledge related to emergency medical protocols, the time taken to obtain oxygen, and operation of the oxygen equipment. Of the subjects tested, 68 percent independently identified the need for oxygen and the correct location of the equipment in the dental school. Only 15 percent of the students completed the experiment within a predetermined optimal time frame, and 50 percent of all students did not successfully operate the tank regulator to administer oxygen correctly. Although most participants in the study were able to verbalize the proper protocol for managing medical emergencies, the chairside execution in this situation demonstrates room for improvement. Incorporation of periodic simulation exercises, in addition to classroom education, is likely to improve the ability of dental students to manage medical emergencies.

Periapical surgery using CAD/CAM guidance: preclinical results.

Apicoectomy is a surgical procedure requiring precise planning and access to locate apices and avoid vital anatomic structures. Traditional methods limit treatment because they rely on two-dimensional radiography and corrective actions during surgery. Surgical guidance, which uses computed tomography and computer-aided design and computer-aided manufacturing processing, has been utilized in dentistry, but not in endodontics. Therefore, the aim of this study was to introduce periapical surgical guidance using computed tomography and computer-aided design and computer-aided manufacturing surgical guides and to compare apical access accuracy using guidance versus a conventional method. Results showed that distance from the apex was 0.79 mm (+/-0.33 SD) using guidance and 2.27 mm (+/-1.46 SD) using freehand drilling. An error greater than 3 mm occurred over 22% of the time freehand, yet never occurred with guidance. This in vitro study suggests that greater accuracy and consistency can be achieved during endodontic surgery with surgical guidance. Advantages also include presurgical visualization in three dimensions.
