Area of Science:

Dentistry

Periodontics

Background:

Hemisection is a conservative surgical procedure for multi-rooted teeth.
It involves removing a diseased root and its associated crown portion while retaining the healthy root and crown.
Indications include localized periodontal disease, resorption, perforation, or caries affecting only one root.

Observation:

This case report focuses on a mandibular molar requiring hemisection.
The primary indication for treatment was extensive root caries affecting one root.
The contralateral root was deemed largely healthy and suitable for preservation.

Findings:

The hemisection procedure was successfully performed, excising the carious root.
The remaining healthy root and crown portion were preserved.
Appropriate restoration of the treated tooth was completed post-surgery.

Implications:

Hemisection offers a viable alternative to extraction for salvageable multi-rooted teeth.
Careful case selection and execution are paramount for predictable long-term outcomes.
This approach can help maintain the dental arch form and function.
