AI Article Synopsis

  • The study aimed to assess how different prophylaxis methods and etching times affect the retention of a light-cured sealant on extracted third molars.
  • Eighty third molars were divided into eight groups based on two prophylaxis types (pumice powder, fluoridated paste, sodium bicarbonate spray, and control) and varying etching times (30 seconds and 15 seconds).
  • Results showed no significant difference in retention between the two etching times, but sodium bicarbonate and fluoridated paste demonstrated significantly better sealant retention compared to other prophylaxis methods.

Article Abstract

The objective of this study was to evaluate the retention of a light-cured sealant using previously different prophylaxis methods and two different etching times, thirty and fifteen seconds. Eighty, third molars surgically extracted were sectioned into two halves (buccal and lingual). The teeth were divided into 8 groups of 20 samples each, according to prophylaxis type: pumice powder, fluoridated paste, sodium bicarbonate spray, and control (no prophylaxis); and etching time: 30 and 15 seconds. Tensile bond strengths were studied using a universal Instron testing machine. A statistical test ANOVA was used. No statistical differences were found when comparing both etching times, but when prophylaxis methods were compared a statistically significant higher retention was found in the sodium bicarbonate and fluoridated paste groups.

This review documents the importance of postoperative interventions that accelerate the functional recovery of the thoracic surgical patient. Enhanced recovery after surgery (ERAS) pathways aim to mitigate the harmful surgical stress response. Improvements to the entire patient pathway, by removing unnecessary care elements while introducing evidence-based interventions, have synergistic effects.

The objectives of this minireview are two-fold. The first is to discuss the evolution of opioid analgesia in perioperative medicine in the context of thoracic non-cardiac surgery. Current standard-of-care, aiming to optimize analgesia and limit undesirable side effects, is discussed in the context of multimodal analgesia, specifically enhanced recovery after thoracic surgery pathways.

Effective pain control is crucial in the management of thoracic surgical patients since it reduces postoperative morbidity and promotes recovery. These patients have co-existing respiratory diseases and impaired pulmonary function, which may be further impaired by surgery. With the adoption of minimally invasive surgical techniques and an emphasis on enhancing recovery after surgery, multimodal analgesia has gained popularity as a way to reduce perioperative opioid use and its associated adverse events such as respiratory depression.

Health care workers are at risk of infection from aerosolization of respiratory secretions, droplet and contact spread. This has gained great importance after the COVID19 pandemic. Intra-operative aerosol-generating procedures are arguably unavoidable in the routine provision of thoracic anesthesia.
