ABSTRACT
Objective: Resident autonomy in an operation theatre has been directly linked with patient safety in healthcare. The objective of this study was to identify the factors necessary for making resident-entrustment decisions from the perspective of a supervisor/consultant viewpoint. The second objective was to develop a checklist for assessing resident readiness for independent work. Materials and methods: This study employed a mixed-method Delphi approach. In the first stage, a comprehensive literature review and a qualitative exploratory study produced a list of factors related to residents. The second phase involved content validation by a panel of experts, followed by a two-round Delphi study with 20 expert panelists. Results: A total of 49 resident-related factors for entrustment were identified, which were reduced to 46 after content validation. During Delphi Round I, 17 factors were fully accepted, 7 were rejected and 22 items were partially accepted. Out of the 39 items sent to Delphi Round II, 23 items were accepted and 16 were rejected. A final 23-item checklist was formed based on the following factors; 6 Cognitive (knowledgeable, risk manager, safe doctor, general manager, field of interest, communicator), 5 Psychomotor (past performer, competent, ability to pick critical findings, ability to act situationally, decision maker) and 12 affective (responsible, leader, honest, empathetic, ethical, receptive, humble, emotionally intelligent, motivated, accountable, team player, disciplined) factors. Conclusion: The study resulted in the formation of a checklist based on the factors necessary for entrustment decision-making in surgical operating rooms. Some of the novel contextual factors were 'general manager', 'field of interest', 'ability to pick critical findings', 'accountable', 'risk manager', and 'past performer'. This framework offers a guideline for supervisors and residents to evaluate progress throughout the residency program. The developed tool demonstrates good content validity and is suitable for entrustment assessment following construct validation.
ABSTRACT
Aim: This study aimed to know the potential of diode light amplification by stimulated emission of radiation (LASER) and desensitizing agents on blocking the dentinal tubules, which may further help in reducing the most common dental problem named dentinal hypersensitivity (DH). Materials and Methods: Sixty human permanent bicuspids were selected, and preparation was performed in the cervical region measuring 2.5 mm × 2.5 mm × 2.5 mm, followed by acid etching for 15 seconds. These are then divided according to the groups mentioned: group 1-nano-hydroxyapatite (HA) was applied for 15 minutes; group 2-biosilicate was applied for 15 minutes; group 3-diode LASER application was performed twice for 60 seconds in noncontact mode; group 4-nano-HA plus diode LASER application; and group 5-biosilicate plus diode LASER application. The same procedure was followed on the 1st, 7th, and 14th days and then rinsed and stored in artificial saliva, and the saliva was changed every 24 hours. The dentinal tubular occlusion was observed under a scanning electron microscope (SEM) after the 14th day. Result: The maximum dentinal tubular occlusion was observed in group 4, where nano-HA and diode LASER application was performed. Conclusion: All the investigated treatment groups have promising occluding potential, but the maximum was found in group 4 >group 5 >group 3 >group 1 >group 2. LASER plus desensitizing together prove to be potent and effective in reducing dentinal tubular diameter.
