"Evaluating the Impact of Diverse Antimicrobial Agents on Clinical Outcomes of Various Frenectomy Techniques: A Retrospective Study"

The frenulum is a mucosal fold, usually containing closed muscle fibers, that connects the lips and cheeks to the alveolar mucosa and/or gingiva and underlying periosteum. The frenulum problem is most common on the labial surface between the maxillary and mandibular central incisors and in the canine and premolar areas. 1 The labial frenulum restricts and stabilizes lip movement and can also cause gingival recession. 1 Depending on the attachment extension of the fibers, the frenulum is classified as follows: Mucosal; when the frenal fibers are attached up to the mucogingival junction, Gingiva; when fibers are placed inside the attached gingiva, Papillary; when fibers extend towards the interdental papilla, Penetrating the papilla; when the frenal fibers cross the alveolar process and extend to the palatine papilla. 2 Clinically, papillary and papillary-penetrating frenulum are considered pathologic and have been associated with papilla loss, recession, diastema, difficulty in brushing, tooth alignment and psychological disturbances of the individual. 3,4 Frenectomy is the complete removal of the frenulum, including its attachment to the underlying bone. There are two techniques for frenectomy. One is the traditional technique using scalpels and periodontal blades, and the other is the technique using soft tissue lasers. 5,6 Er:YAG is highly effective in cutting soft tissues. Its wavelength is 2940 nm, allowing for shallow penetration and a high water absorption rate. This type of laser can be strongly absorbed by water molecules in the irradiated area, producing a photoelectric effect that causes the water temperature to rise sharply.

Both techniques have some disadvantages; the traditional scalpel technique results in a large rhomboidal wound area at the bottom where primary closure is not possible, and healing occurs with secondary intention. It also causes more pain and discomfort to the patient compared to the laser technique. 7 On the other hand, the laser is an expensive device, and its use requires more precision and control, causing bone necrosis if the beam contacts the bone surface.

Chlorhexidine (CHX) is a cationic bisbiguanide compound with broad-spectrum antimicrobial properties. Although the mouthwash form is most used in dentistry after surgical procedures, gel, spray and dental varnish forms are also preferred for their antiplaque and healing acceleration properties. 8 Klorhex Plus mouthwash, containing 0.5 g flurbiprofen and 0.24 g chlorhexidine digluconate has also been shown to have significant contributions in reducing edema and accelerating wound healing in oral wounds.9
