Parental Acceptance of Moderate Sedation and Associated Techniques for Behavior Management in Saudi Arabia: A Cross-Sectional Study.
Patient Prefer Adherence
January 2025
Department of Pediatric Dentistry and Orthodontics, College of Dentistry, King Saud University, Riyadh, Saudi Arabia.
Purpose: This study aimed to evaluate the acceptance of moderate sedation (MS) as a behavior guidance technique (BGT) method among Saudi parents, and also assess their acceptance of other BGTs, including parental separation, papoose board (PB), and nitrous oxide (NO), used in conjunction with MS.
Patients And Methods: This cross-sectional study was conducted at the Dental University Hospital, King Saud University, Riyadh, Saudi Arabia. It involved Saudi parents of children aged 3-5 years undergoing dental treatment with MS, alongside additional BGTs such as parental separation, PB, and NO.
We demonstrate a broadband photothermal spectroscopy in the mid-infrared region using a quantum cascade laser frequency comb operating between ∼7.7 and ∼8.2 µm covering a frequency range of ∼70 cm.

Recreational use of nitrous oxide (NO) has risen dramatically over the past decades. This study aimed to examine its rewarding effect and the underlying mechanisms. The exposure of mice to a subanesthetic concentration (20%) of NO for 30 min for 4 consecutive days paired with NO in the morning and paired with the air in the afternoon produced apparent rewarding behavior in the conditioned place preference (CPP) paradigm.

Nitrous oxide (NO) abuse is becoming increasingly popular worldwide. Moreover, the use of NO combined with other substances, such as alcohol, is also common. Accidental deaths associated with NO abuse are rare in forensic practice, with most fatal cases involving continuous inhalation equipment or exposure in a confined space.

The photochemistry of nitrous acid (HONO) plays a crucial role in atmospheric chemistry as it serves as a key source of hydroxyl radicals (OH) in the atmosphere; however, our comprehension of the underlying mechanism for the photochemistry of HONO especially in the presence of water is far from being complete as the transient intermediates in the photoreactions have not been observed. Herein, we report the photochemistry of microsolvated HONO by water in a cryogenic N matrix. Specifically, the 1:1 hydrogen-bonded water complex of HONO was facially prepared in the matrix through stepwise photolytic O oxidation of the water complex of imidogen (NH-HO) via the intermediacy of the elusive water complex of peroxyl isomer HNOO.
