Summary
Odontogenic sinus tracts, often misdiagnosed, can present as facial skin lesions. Prompt dental evaluation is crucial for accurate diagnosis and effective treatment of these conditions.
Area of Science:
- Oral and Maxillofacial Surgery
- Dermatology
- Infectious Diseases
Background:
- Cutaneous sinus tracts of odontogenic origin are documented but frequently misdiagnosed.
- Chronic periapical periodontitis, a common dental issue, can manifest as asymptomatic skin lesions.
Observation:
- A 75-year-old woman presented with a painful left cheek skin lesion.
- Examination revealed a subcutaneous nodule with erythematous skin.
- Pus cultures identified Bacteroides and Peptostreptococcus species.
Findings:
- Histopathology confirmed a focal abscess in the dermis and subcutaneous tissue.
- Dental imaging revealed a periapical abscess at the left lower first molar.
- Combined antibiotic and root canal therapy resolved the lesion.
Implications:
- A high index of suspicion is necessary for diagnosing facial lesions of odontogenic origin.
- Early dental assessment is vital for correct diagnosis and management.
- This case highlights the importance of interdisciplinary collaboration in managing complex infections.

01:23Skin 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...

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.

01:15Teeth
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...
