    Assessing Effectiveness of an Audiovisual Educational Tool for Improving Dental Students' Probing Depth Consistency
    (Wiley, 2019-04) Prabhu, Srividya; John, Vanchit; Blanchard, Steven; Eckert, George J.; Hamada, Yusuke; Periodontology, School of Dentistry
    Dental students often underestimate their probing depth (PD) measurements, which emphasizes the need for effective and novel methods for teaching proper probing technique. The aim of this study was to evaluate the efficacy of audiovisual learning aids, recorded from the point of view of examiners, for improvement in PD agreement in dental students. In 2017‐18, 22 third‐year dental students were randomized into test and control groups. Each student and a single blinded faculty examiner performed PD measurements on a minimum of three patients. The test group viewed a video demonstrating proper probing technique, while the control group received only probing technique instruction from prior lectures. All measurements, the periodontal diagnoses, and the total time taken to complete PD measurements were recorded. A survey of student attitudes about the audiovisual tool was conducted after the intervention; all 22 students completed the survey. A total of 11,426 PD sites were measured. The test group had 10% greater accuracy in PD sites=4 mm. The control group had a minor but statistically significant increase in accuracy for 2 mm PD sites. For all incorrect measurements at sites PD≥4, the students tended to underestimate the PD. Tooth type, site location around tooth, and diagnosis had no significant effect on PD measurement agreement. No significant difference between groups was found for the proportions of gingivitis and periodontitis patients or for examination time. This study found that use of the audiovisual learning aid “Calibrated Periodontal Training Video” improved the students' probing depth accuracy for sites with PD of 4 mm.

    Treatment of an Erratic Extraction Socket for Implant Therapy in a Patient with Chronic Periodontitis
    (Hindawi Publishing Corporation, 2016) Hamada, Yusuke; Prabhu, Srividya; John, Vanchit; Department of Periodontics & Allied Dental Programs
    As implant therapy becomes more commonplace in daily practice, preservation and preparation of edentulous sites are key. Many times, however, implant therapy may not be considered at the time of tooth extraction and additional measures are not taken to conserve the edentulous site. While the healing process in extraction sockets has been well investigated and bone fill can be expected, there are cases where even when clinicians perform thorough debridement of the sockets, connective tissue infiltration into the socket can occur. This phenomenon, known as "erratic healing," may be associated with factors that lead to peri-implant disease and should be appropriately managed and treated prior to surgical implant placement. This case report describes the successful management of an erratic healing extraction socket in a 62-year-old Caucasian male patient with chronic periodontitis and the outcomes of an evidence-based treatment protocol performed prior to implant therapy. Careful preoperative analysis and cone beam computed tomography imaging can help detect signs of impaired healing in future implant sites and prevent surgical complications.
