Oral and dental affections in mercury-exposed workers
Community Dentistry and Oral Epidemiology
|July 1, 1978
Summary
This study investigated oral health in 222 mercury-exposed workers. High mercury vapor levels and exposure duration were key factors, but oral hygiene and sensitivity also played roles, not allergy.
Area of Science:
- Occupational Health
- Toxicology
- Dental Medicine
Background:
- Workers in Chlor-Alkali plants face potential exposure to mercury vapor.
- Occupational mercury exposure is linked to various health concerns, including oral manifestations.
Purpose of the Study:
- To investigate the prevalence and nature of oral and dental affections in mercury-exposed workers.
- To identify factors contributing to oral health issues in this occupational group.
Main Methods:
- A cohort of 222 workers from a Kuwaiti Chlor-Alkali plant with varying mercury exposure levels (0.3–566.6 µg/m³) and durations (1–11 years) were examined.
- Oral examinations were conducted to assess signs and symptoms of dental and oral affections.
- Factors including mercury exposure levels, exposure duration, oral hygiene, and individual sensitivity were considered.
Main Results:
- Oral affections were observed in mercury-exposed workers.
- Higher mercury vapor levels and longer exposure periods correlated with increased oral signs and symptoms.
- Oral hygiene status and individual sensitivity were significant contributing factors to oral affections.
- The study found no evidence of oral affections being caused by an allergic reaction to mercury.
Conclusions:
- Occupational mercury exposure in Chlor-Alkali plants can lead to oral health problems.
- Both environmental factors (mercury levels, exposure duration) and individual factors (oral hygiene, sensitivity) influence the development of oral affections.
- Allergy to mercury is not a likely cause of the observed oral affections in this worker population.

01:14Assessing Body Temperature - Oral
Here are the steps to accurately measure oral temperature using an electronic thermometer:
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...

01:15Teeth
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 and...

01:21Tooth Anatomy
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 grinding food.

01:26Assessment 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.

01:27The 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...
01:28Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
