Assessment of the Mouth01:26

Assessment of the Mouth

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.
Psychosexual Stages of Personality: Oral01:16

Psychosexual Stages of Personality: Oral

The oral stage is the initial phase of Sigmund Freud's theory of psychosexual development, occurring from birth to approximately 12 to 18 months. During this period, the infant's mouth serves as the primary source of pleasure, with actions such as sucking, chewing, biting, and drinking playing a crucial role in reducing tension. These activities are essential not only for nourishment but also for the infant's psychological and emotional satisfaction.

The Oral Microbiota01:27

The Oral Microbiota

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...
Olfactory Receptors: Location and Structure01:03

Olfactory Receptors: Location and Structure

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...
Self-Discrepancy Theory02:45

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.
Assessment of the Gastrointestinal System I: Subjective Data01:17

Assessment of the Gastrointestinal System I: Subjective Data

Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health History
The initial step in assessing the GI system is obtaining a comprehensive health history. This includes inquiring about the patient's history or presence of problems related to...

Summary

Self-perceived bad breath is unreliable for assessing oral malodor. Clinical assessment revealed different risk factors than self-assessment, highlighting the need for professional diagnosis of halitosis.

Area of Science:

  • Dentistry
  • Oral Health
  • Halitosis Research

Background:

  • Oral malodor (halitosis) significantly impacts social interactions and quality of life.
  • Accurate self-assessment of oral malodor is challenging, necessitating objective clinical evaluation.

Purpose of the Study:

  • To compare subjective self-perceived oral malodor with objective clinical measurements.
  • To identify and analyze risk factors associated with both self-perceived and clinical oral malodor.

Main Methods:

  • A cross-sectional study involving 565 dental patients.
  • Data collection included sociodemographics, dental hygiene behaviors, and self-reported halitosis.
  • Clinical oral malodor assessment, oral health status evaluation, and N-benzoyl-DL-arginine-2-napthilamide (BANA) test for tongue coating proteolytic activity were performed.

Main Results:

  • Self-perceived oral malodor demonstrated low sensitivity (47.2%) and specificity (59.2%).
  • Risk factors for self-perceived malodor included smoking and alcohol consumption.
  • Clinical oral malodor was associated with lower education, infrequent dental visits, poor tongue cleaning, mouthwash use, periodontal pockets, gingivitis, tongue coating, and high BANA scores.

Conclusions:

  • Self-perception is an unreliable indicator for judging personal oral malodor.
  • The determinants of self-perceived oral malodor differ significantly from those identified through clinical assessment, underscoring the importance of professional halitosis evaluation.
