Teeth

2.0K
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...

Tooth Anatomy

2.5K
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...

Olfactory Receptors: Location and Structure01:03

Olfactory Receptors: Location and Structure

13.6K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

Bone Disorders01:29

Bone Disorders

5.8K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

7.7K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

4.0K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Summary

Maxillary sinus volume and dimensions decrease with age and tooth loss. Older patients and those who are completely or partially edentulous have smaller maxillary sinuses, impacting anatomical measurements.

Area of Science:

  • Anatomy
  • Radiology
  • Gerodontology

Background:

  • The maxillary sinus is a crucial anatomical structure in the craniofacial complex.
  • Understanding its dimensional variations is vital for dental and surgical procedures.

Purpose of the Study:

  • To investigate the correlation between patient-dependent variables (age, gender, edentulism) and maxillary sinus dimensions.
  • To analyze variations in maxillary sinus volume, wall distances, septa height, and cavity height.

Main Methods:

  • Cross-sectional study involving 394 cone-beam computed tomography (CBCT) scans.
  • Standardized measurements of maxillary sinus volume, mediolateral dimensions, and height.
  • Evaluation of patient age, gender, and edentulism status.

Main Results:

  • Significantly smaller maxillary sinus volume in edentulous patients compared to dentate subjects.
  • Age demonstrated an inverse correlation with sinus volume, mediolateral dimensions, and distance to the meatus.
  • Prevalence of accessory meatus was 29.19%.

Conclusions:

  • Maxillary sinus dimensions are significantly influenced by aging and tooth loss.
  • Aging and edentulism lead to reduced maxillary sinus volume and altered dimensions.
