Assessment of the Mouth

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.

Herpes

Herpes

Herpes simplex type 1 (HSV‑1) is a widespread pathogen responsible for orolabial lesions. It is an enveloped, double-stranded DNA (dsDNA) virus belonging to the family Herpesviridae. Once the virus infects a host cell, its double‑stranded DNA genome is delivered into the nucleus, where a coordinated cascade of immediate‑early, early, and late gene expression directs viral DNA replication, structural protein synthesis, and virion assembly. After primary infection of epithelial cells, HSV-1...

Oral Cavity

Oral Cavity

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...

Skin Diseases and Disorders

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Skin Cancer

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Peptic Ulcer Disease III: Clinical Manifestations and Complications

Peptic Ulcer Disease III: Clinical Manifestations and Complications

Duodenal UlcersDuodenal ulcers are the most common form of peptic ulcer disease, presenting with chronic, intermittent epigastric pain. Pain typically appears 2–3 hours after meals, especially when the stomach is empty, often waking patients at night. It is characteristically relieved by food or antacids (“pain–food–relief”). Some patients remain asymptomatic until complications like bleeding or perforation emerge, particularly with NSAID or anticoagulant use.Gastric UlcersGastric ulcers share...

Summary

This summary is machine-generated.

Psoriasis patients show a higher prevalence of fissured and geographic tongue compared to the general population. These oral signs, particularly fissured tongue, are strongly linked to pustular psoriasis.

Area of Science:

Dermatology
Oral Medicine
Clinical Research

Context:

Limited literature exists on oral manifestations in psoriasis.
Pustular psoriasis forms are often associated with oral signs, notably geographic tongue.
The prevalence of fissured tongue in psoriasis patients requires further investigation.

Purpose:

To determine the types and prevalence of oral signs in a large cohort of psoriasis patients.
To compare the incidence of oral signs in psoriasis patients versus a control group.
To investigate the correlation between specific oral signs and different forms of psoriasis.

Summary:

A study of 400 psoriasis patients and 1000 controls revealed significantly higher rates of fissured tongue (33.2% vs 9.9%) and geographic tongue (7.7% vs 1%) in psoriasis patients.
Fissured tongue showed a strong correlation with pustular psoriasis (83.3% of pustular psoriasis patients).
Geographic tongue prevalence in psoriasis patients aligns with existing literature, while fissured tongue prevalence was notably higher than previously reported.

Impact:

Establishes a strong correlation between psoriasis and fissured/geographic tongue, though not pathognomonic.
Highlights the increased prevalence of fissured tongue in psoriasis patients.
Suggests that fissured and geographic tongue are particularly associated with pustular psoriasis, even if patients are often unaware of these signs.
