Summary
External cervical resorption (ECR) is often linked to orthodontic treatment, dental trauma, and cat ownership. Identifying these factors aids in the early diagnosis of ECR.
Area of Science:
- Endodontics
- Dental Traumatology
- Periodontology
Background:
- External cervical resorption (ECR) is a complex pathological process affecting the external root surface of teeth.
- Understanding predisposing factors is crucial for early detection and management of ECR.
Purpose of the Study:
- To investigate the prevalence of ECR in relation to patient demographics and potential contributing factors.
- To identify associations between ECR and variables such as sex, age, tooth type, and lifestyle.
Main Methods:
- A retrospective analysis of 215 ECR lesions from 194 patients treated between 2017 and 2022.
- Patient interviews using a checklist of potential predisposing factors, including orthodontic history, dental trauma, cat ownership, and parafunctional habits.
- Statistical analysis to determine significant associations between ECR and patient/factor variables.
Main Results:
- A sole predisposing factor was identified in 57.7% of cases, with combined factors in 20%.
- The most frequent factors were orthodontic treatment (25.6%), dental trauma (20.9%), cat ownership (15.8%), and parafunctional habits (10.2%).
- Significant associations were found between ECR and tooth type, jaw location, trauma history, cat ownership, and parafunctional habits, with differences noted between sexes.
Conclusions:
- Orthodontic treatment, dental trauma, and cat ownership are significant identified predisposing factors for ECR.
- These findings can assist clinicians in the early diagnosis and risk assessment of external cervical resorption.

01:31Internal Receptors
57.5K
Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.

02:30Naturalistic Observations

If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

01:20Receptor-mediated Endocytosis
10.3K
Receptor-mediated endocytosis is when bulk amounts of specific molecules are imported into a cell after binding to cell surface receptors. The molecules bound to these receptors are taken into the cell through inward folding of the cell surface membrane, which is eventually pinched off into a vesicle within the cell. Structural proteins, such as clathrin, coat the budding vesicle.

01:16Methods for Studying Drug Absorption: In vitro
847
In vitro experiments are crucial for understanding the transport and absorption of drugs through biological materials. These studies employ varied methods such as the diffusion cell method, the everted sac technique, and the everted ring technique.
The diffusion cell method uses a two-compartment cell, including a donor compartment with the drug solution, which simulates the environment where the drug is applied, and a receptor compartment with a buffer solution, which simulates the environment...

889
In situ experiments, such as the Doluisio method and Single-Pass Perfusion technique, provide critical insights into drug uptake by simulating in vivo conditions for drug absorption.
The Doluisio method involves perfusing a prepared segment of a rat's small intestine with a solution of radiolabeled drug and a non-absorbable marker. This helps to differentiate between absorbed and non-absorbed drug concentrations. The intestinal segment is connected at both ends using tubing and syringes,...
