Substance Use Disorders Affecting Sleep

Substance Use Disorders Affecting Sleep

Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

Drug Toxicity: Dose-Dependent Reactions

Drug Toxicity: Dose-Dependent Reactions

Drug toxicities can be stratified into pharmacological, pathological, or genotoxic based on their mechanisms. The incidence and severity of these toxicities generally increase with the drug's concentration in the body and exposure time.Pharmacological toxicity is evident when the therapeutic effects of drugs overshoot into adverse reactions in a predictable, dose-dependent manner. Central nervous system (CNS) depression from barbiturates is a classic example, with effects escalating from...

Tooth Anatomy

Tooth Anatomy

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

Drug Toxicity: Overview

Drug Toxicity: Overview

Drug toxicity quantifies the harm a compound causes to an organism, varying by dose and potentially impacting whole systems or specific organs like the liver. Toxic reactions may arise from venomous insect or spider bites, with effects ranging from mild symptoms to severe outcomes such as brain damage or death. Common forms of acute poisoning include ethanol intoxication and overdose of pain or fever medications, with substances like GHB and heroin being particularly lethal at doses close to...

Local Anesthetics: Adverse Effects

Local Anesthetics: Adverse Effects

While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

Local Anesthetics: Chemistry and Structure-Activity Relationship

Local Anesthetics: Chemistry and Structure-Activity Relationship

Local anesthetics (LAs) are drugs that induce a temporary loss of sensation in a limited body area, preventing pain. Cocaine was the first local anesthetic discovered in the late 19th century. Cocaine is a benzoic acid ester obtained from the leaves of coca shrubs and was often used for its psychotropic effects. Cocaine was first isolated in 1860 by Albert Niemann. Sigmund Freud studied the physiological actions of cocaine. Carl Koller later introduced it into clinical practice in 1884 as a...

Area of Science:

Forensic Science
Dental Forensics
Toxicology

Background:

Dental hard tissues offer durable traces for forensic investigation due to resistance to degradation.
Analyzing dental tissues for substances and trace elements is a developing area in forensic science.

Purpose of the Study:

To explore the potential of dental tissue analysis for detecting substances and trace elements.
To assess professional knowledge and training regarding substance-related dental alterations.
To develop educational resources, specifically 3D models, to aid in identifying these changes.

Main Methods:

A scoping review of scientific literature on PubMed, Scopus, and Web of Science.
A global e-survey distributed to forensic and dental professionals.
Development of 3D digital models of substance-induced dental changes using specialized software.

Main Results:

Scientific literature predominantly features experimental studies on drug detection in molars and premolars using chromatography and mass spectrometry.
Survey results indicate limited formal education (35.6%) and confidence (14.4%) among professionals in identifying substance-related dental changes, with low accuracy (8.1%) in image-based assessments.
3D models of licit drugs, illicit drugs, and chemicals/elements were created and made accessible online.

Conclusions:

There is a significant gap in professional training and awareness regarding the recognition of substance-induced dental alterations, particularly for illicit drugs.
Existing educational and visual resources are insufficient for forensic practitioners.
The developed 3D digital models serve as a crucial educational tool to enhance awareness and support casework involving dental evidence of substance use.
