Tooth Anatomy01:21

Tooth Anatomy

2.8K
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...

Teeth

2.2K
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

The Oral Microbiota01:27

The Oral Microbiota

35
The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...

Anatomy of Respiratory System I: Upper Respiratory Tract01:29

Anatomy of Respiratory System I: Upper Respiratory Tract

6.4K
The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract....

Oral Cavity01:11

Oral Cavity

3.9K
The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

Physical Assessment of the Respiratory Tract I: Health History01:28

Physical Assessment of the Respiratory Tract I: Health History

1.2K
Physical assessment of the respiratory tract is critical to patient care. It allows healthcare professionals to identify and manage various respiratory conditions. The process involves a combination of subjective and objective data collection.
Subjective Data
Subjective data provides vital information about the patient's health history and symptoms. This data is typically collected through interviews in which patients describe their experiences, symptoms, and concerns.
Health history and...

Summary

Dental roots near the maxillary sinus are linked to sinus pathologies. Teeth with roots in the maxillary sinus are 1.82 times more associated with diseased sinuses, potentially causing inflammation.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Radiology
  • Otolaryngology

Background:

  • Proximity of dental roots to the maxillary sinus poses risks.
  • Understanding this relationship is crucial for preventing complications.

Purpose of the Study:

  • To evaluate the spatial relationship between healthy tooth roots and the maxillary sinus.
  • To determine the association between root proximity and the incidence of sinus pathologies.

Main Methods:

  • Analysis of 109 cone beam computed tomography (CBCT) scans by three radiologists.
  • Assessment of intra- and inter-rater agreement using the Kappa test.
  • Statistical analysis (chi-squared test, prevalence ratio) to test the hypothesis.

Main Results:

  • High intra- and inter-rater reliability.
  • A statistically significant difference in root presence between diseased (6.09%) and normal (3.43%) maxillary sinuses (p=0.006).
  • Roots in the maxillary sinus were 1.82 times more associated with diseased sinuses (p<0.0001).

Conclusions:

  • Dental roots within the maxillary sinus are significantly associated with sinus pathologies.
  • The presence of roots in the sinus may trigger inflammatory responses in the sinus membrane.
  • Dental procedures could potentially worsen these sinus conditions.
