Assessment of the Mouth01:26

Assessment of the Mouth

846
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.

Ethnic Identity within a Larger Culture01:27

Ethnic Identity within a Larger Culture

179
Adolescents from ethnic minority backgrounds face a multifaceted journey in forming their identities, shaped by the intersections of cultural expectations and personal exploration. For these adolescents, identity formation involves not only typical developmental challenges but also navigating the perceptions and attitudes of the majority culture. As they grow, adolescents in ethnic minority groups often become increasingly aware of stereotypes, social biases, and discrimination, all of which...

Oral Cavity01:11

Oral Cavity

2.6K
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...

Surveys

16.5K
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Enteral Nutrition I: Orogastric and Nasogastric Feeding

910
Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...

Pharynx01:20

Pharynx

5.1K
The pharynx, a tubular structure framed by skeletal muscle and lined with mucous membrane, extends continuously from the nasal cavities. It is segmented into three major areas: the nasopharynx, oropharynx, and laryngopharynx.
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...

Area of Science:

  • Anthropology
  • Oral health
  • Biometrics

Background:

  • Maximum mouth opening (MMO) is a critical clinical parameter.
  • MMO exhibits variations based on race, gender, age, and anthropometry.

Purpose of the Study:

  • To ascertain maximal mouth opening (MMO) across Nigeria's major ethnic groups.
  • To identify predictors of MMO within these diverse populations.

Main Methods:

  • A study involving 449 adults (18-74 years) from three major Nigerian ethnic groups.
  • MMO and anthropometric measurements were collected and analyzed using univariate and multivariate linear regression.

Main Results:

  • The overall mean MMO was 49.33 ± 7.91mm.
  • Yoruba individuals exhibited significantly higher MMO (53.06 ± 6.27mm) compared to Hausa (52.77 ± 8.06mm) and Igbo (47.59 ± 8.61mm) groups.
  • Age and height were identified as independent predictors of MMO.

Conclusions:

  • Significant ethnic variations in MMO exist among Yoruba, Hausa, and Igbo populations in Nigeria.
  • Age and height are crucial independent predictors for maximum mouth opening.
