Oral Cavity01:11

Oral Cavity

3.6K
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...

Tooth Anatomy

2.6K
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...

Suctioning the Oropharyngeal Airway

1.3K
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

Assessment of the Mouth01:26

Assessment of the Mouth

1.4K
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

Teeth01:15

Teeth

2.1K
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...

Epistaxis01:30

Epistaxis

699
Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

Area of Science:

  • Psychiatry
  • Dentistry
  • Neurology

Background:

  • Cenesthopathy presents as abnormal bodily sensations, classified under delusional or somatoform disorders.
  • Oral cenesthopathy, a frequent manifestation, involves unusual oral sensations like excessive mucus or a feeling of foreign bodies.
  • Patients often seek dental treatment due to the oral focus, complicating diagnosis and management.

Purpose of the Study:

  • To review the various aspects of oral cenesthopathy.
  • To highlight the diagnostic and therapeutic challenges posed by this condition.
  • To underscore the need for further research into its epidemiology, pathophysiology, and treatment.

Main Methods:

  • Literature review focusing on case reports and existing studies on oral cenesthopathy.
  • Analysis of prevalence data from psychiatric and psychosomatic dentistry clinics.
  • Examination of suggested pathophysiological mechanisms, including cerebral blood flow asymmetry.

Main Results:

  • Prevalence estimates vary significantly, with higher rates in psychosomatic dentistry settings.
  • Elderly women appear to be a commonly affected demographic, though disposition is unclear.
  • Potential therapeutic approaches include antidepressants, antipsychotics, ECT, and psychotherapy, but the condition is often intractable.

Conclusions:

  • Oral cenesthopathy is frequently overlooked in mainstream medicine, presenting a diagnostic dilemma for dentists.
  • The pathophysiology remains largely unknown, with preliminary evidence suggesting cerebral blood flow asymmetry.
  • Large-scale, rigorous clinico-statistical and case-control studies are essential to advance understanding and treatment of oral cenesthopathy.
