Impact of dental school critical thinking demonstrations carryover to practice: Survey of 5-year graduates.

Introduction: Little literature exists on graduates' application to practice for explicit critical thinking skills learned in dental school.

Purposes: Discern the (1) degree to which graduates apply explicit critical thinking skillsets in practice; (2) degree of adaptation of critical thinking skillsets to practice; (3) frequency of use for critical thinking skillsets in practice; and (4) perceptions to improve critical thinking learning guidance in dental school.

Methods: Five critical thinking exercises/skillsets were selected that had been in place over 5 years with at least one paper: geriatrics, treatment planning, technology decision making, ethics, evidence-based dentistry; each followed concepts from an emulation model in critical thinking.

Dental students' perceptions of standardized patient experiences using Zoom: Dyadic factors.

Purpose: The COVID-19 pandemic required a rapid transition to online education, including simulations. The current study identified students' perceptions of communicating with standardized patients in a virtual setting.

Methods: This qualitative study thematically analyzed 485 reflections submitted by 248 students between Spring 2020 and Spring 2022.

Differential Effect of Fixed Ratio Magnitude on the Rate of Lever-Pressing and Interinjection Intervals of Cocaine Self-Administration in Rats.

Background: Many features of self-administration behavior may be explained by reference to the properties of schedules of reinforcement. Schedules alter the probability of a behavior being reinforced and thereby increase, or decrease, the frequency of the behavior and fixed ratio (FR) magnitude reportedly alters the rate of responding to cocaine. A pharmacokinetic/pharmacodynamic interaction theory states that lever-pressing behavior is induced only when cocaine levels in the body are above the priming/remission threshold and below the satiety threshold-a range termed the compulsion zone.

The ascending limb of the cocaine unit dose-response function in rats as an experimental artifact.

The cocaine unit dose-response function is an inverted U with the ascending and descending limbs representing the positive and rate limiting cocaine effects, respectively. Higher fixed ratio (FR) schedules and/or time-out periods make the ascending limb more prominent. Alternatively, a pharmacokinetic/pharmacodynamic interaction theory demonstrates that cocaine-induced lever pressing occurs only when cocaine levels are within a range termed the compulsion zone.

SCH23390 and a humanized anti-cocaine mAb decrease the latency to cocaine-induced reinstatement of lever pressing behavior in rats that self-administer cocaine.

In rats that self-administer cocaine, the latency to the reinstatement of lever pressing behavior induced by a single dose of cocaine is due to the time taken for cocaine levels to fall to the satiety threshold. The D1 dopamine receptor antagonist SCH23390, and the recombinant humanized anti-cocaine mAb h2E2 increase the cocaine satiety threshold and would be expected to alter the latency to reinstatement. Male rats acquired cocaine self-administration behavior on an FR1 schedule.

Outcomes of minimal oral sedation in patients treated in a dental school setting: A retrospective study.

Introduction: Minimal sedation (Anxiolysis) is used in dentistry to reduce stress, manage anxiety, and improve patient comfort during treatment. The oral route of minimal sedation is safe and convenient, but there is limited literature assessing the efficacy of this mode of patient care. This paper aims to evaluate the outcomes of oral sedation use for patients treated in a dental school setting using a retrospective cohort analysis of electronic health record data.

The cocaine compulsion zone theory explains the reinstatement of lever pressing behavior in rats in response to a single cocaine dose.

A single non-contingent dose of cocaine reinstates extinguished lever pressing behavior in rats trained to self-administer cocaine. This represents a model of relapse in cocaine use disorder and the number of lever presses has been the standard measure. Lever pressing behavior during self-administration occurs only when cocaine levels are below the satiety threshold and above the remission/priming threshold, a range termed the compulsion zone.

Oral Health Factors Related to Rapid Oral Health Deterioration among Older Adults: A Narrative Review.

Older adults who face systemic health issues and lack adequate social support are at risk for oral health deterioration. How rapidly such changes take place depends on the severity of their medical condition and their ability to access oral health services in a timely manner. The management of dental caries and periodontal disease in this cohort is made complex by the interaction of local and host factors such as the presence of dry mouth, involvement of root surfaces, and altered wound healing.

Rehabilitation of orbital defect with silicone orbital prosthesis retained by dental implants.

Orbital defects can result from cancer, birth anomalies, or trauma leading to an onslaught of problems in the function and psyche of the patient. These defects are restored by surgical reconstruction and followed by placement of orbital prosthesis for cosmetic makeup. The use of dental implants in retaining orbital prosthesis improves patient acceptance of the prosthesis owing to better retention and stability than conventional adhesive retained prosthesis.
