Polybutester (Novafil) sutures offer advantages over traditional materials in wound closure. This study found Novafil easy to handle and potentially better tolerated in oral tissues than nylon.

Area of Science:

  • Surgical Materials Science
  • Dental Sutures
  • Biomaterials

Background:

  • Monofilament nonabsorbable sutures are underutilized in dentistry despite multifilament materials eliciting greater cellular reactions.
  • Commonly used sutures like cotton and silk present disadvantages, including rigidity and package memory.
  • Polybutester (Novafil), a monofilament nonabsorbable material, shows promise but is not widely adopted in dental practice.

Purpose of the Study:

  • To evaluate the clinical response of skin and abdominal wall muscle to Polybutester (Novafil) and nylon sutures in a preclinical model.
  • To compare the handling characteristics and tissue integration of Novafil versus nylon sutures.

Main Methods:

  • Seventy Wistar rats underwent standardized skin and abdominal wall incisions under general anesthesia.

  • Wounds were closed using either Novafil or nylon sutures.
  • Clinical assessment of wound healing was performed at multiple time points up to seven days post-surgery.

    • Main Results:

    • Polybutester (Novafil) demonstrated superior handling properties, including strength, elasticity, and flexibility, facilitating quicker suturing.
    • Some instances of abdominal wound edema were observed.
    • Six animals developed abdominal wound infections within the seven-day observation period.

    Conclusions:

    • Novafil exhibits favorable characteristics for wound closure, potentially offering better patient comfort and tolerability in oral mucosal applications compared to nylon.
    • The material appears suitable for safe use on skin and mucosal surfaces and may be advantageous for internal sutures due to reduced tissue irritation.
