What are the two main types of sutures used in dental procedures?

The correct choice identifies the two main types of sutures used in dental procedures as absorbable and nonabsorbable.

Absorbable sutures are designed to dissolve in the body over time and are typically used for internal suturing where it's unnecessary for the patient to return for suture removal. They are often made from materials that promote healing and reduce the need for follow-up visits. Examples include sutures made from polyglycolic acid or chromic gut.

Nonabsorbable sutures, on the other hand, are meant to remain in the body until they are manually removed, usually during a follow-up appointment. These sutures are often used on the skin's surface or in areas where prolonged support is necessary. Common materials for nonabsorbable sutures include nylon and polyester.

Understanding the differences between these suture types is crucial for dental professionals, as it impacts the management of surgical sites, including infection control and healing processes.
