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...

Anatomical Movements

Anatomical Movements

Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...

The Movement of Organelles and Vesicles

The Movement of Organelles and Vesicles

In eukaryotic cells, cytoskeletal filaments such as actin, microtubules, and intermediate filaments form a mesh-like cytoskeletal network. These filaments serve as tracks for transporting cellular cargo. Specialized motor proteins use the chemical energy stored in adenosine triphosphate (ATP) for this transport. During interphase, microtubules are polarized, with the plus-end towards the cell periphery and the minus-end towards the cell center. Two microtubule-associated motor proteins,...

Gene Therapy

Gene Therapy

Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

Fluid Movement Between Compartments

Fluid Movement Between Compartments

The force applied by fluids against a surface, known as hydrostatic pressure, initiates the transfer of fluid among different compartments. Within our blood vessels, the blood's hydrostatic pressure is a result of the heart's pumping action. At the arteriolar end of capillaries, hydrostatic pressure (capillary blood pressure) exceeds the opposing colloid osmotic pressure created primarily by plasma proteins like albumin. This discrepancy in pressure propels plasma and nutrients from the...

Movement Joints in Buildings

Movement Joints in Buildings

Movement joints in buildings are essential design elements that accommodate inevitable motions caused by various factors such as temperature changes, moisture content variations, and structural deflections. These motions, if not considered in design and construction, can lead to unsightly or dangerous damage. Movement joints are incorporated in different forms to manage these stresses and allow materials to move without causing distress.
The simplest type of movement joints, working joints, are...

Summary

Continuous positive airway pressure (CPAP) therapy can cause unexplained tooth movement due to tongue thrusting. This side effect is reversible with orthodontic treatment, improving patient quality of life and CPAP adherence.

Background:

Positive airway pressure (PAP) therapy is a common treatment for obstructive sleep apnea (OSA).
Nasal pillows interfaces are frequently used for PAP delivery.
Uncommon side effects of medical treatments require thorough documentation.

Observation:

A patient using continuous positive airway pressure (CPAP) for mild OSA experienced unexplained anterior tooth movement and spacing.
The tooth movement began months after initiating CPAP therapy.
The patient reported forward tongue thrusting during CPAP use.

Findings:

The observed tooth movement was directly linked to the use of CPAP therapy and associated tongue thrusting.
Orthodontic treatment successfully corrected the malocclusion caused by the CPAP-induced tooth movement.
Teeth returned to their original positions after 12 months of orthodontic intervention.

Implications:

Tooth movement is a rare but impactful side effect of PAP therapy.
Increased awareness among clinicians can improve patient management and diagnosis.
Addressing this side effect may enhance patient experience and adherence to CPAP treatment for sleep apnea.
