ABSTRACT
A variety of periodontal plastic surgery techniques have been proposed to correct aesthetic and functional problems of periodontal tissues. The most common procedure uses the connective tissue graft from the palate. However, patient discomfort and the limited quantity of palatal tissue results in many cases where the surgeon uses connective tissue substitutes. In this case report, we describe the use of a human dermal matrix for gingival volume augmentation in the lower incisors with a novel modified VISTA technique stabilizing the flap with sutures and cyanoacrylates, avoiding comorbidity of a second surgical site. The follow_up at 6 months showed an increase in gingival thickness and a reduction in recessions length.

Surgeons are always looking for ways to predictably maintain primary closure, to reduce suture migration during cutaneous wound closure, and to keep membranes and graft material intact during clot formation and epithelialization. PeriAcryl® by GluStitch Inc is a product that compliments these surgical scenarios. PeriAcryl® is a cyanoacrylate that is available in two viscosities – high and regular. It can be flash-set by applying saline to its surface. It is biologically compatible and has been tinted violet so that it is easy to visualize at the surgical sites. I have seen the best results by routinely using PeriAcryl® for socket grafting, with or without immediate implant placement, and as protection over sutures after tension-free primary closure.

]]>This clinical study was conducted to evaluate the impact of different hemostatic treatments following palatal gingival harvesting on patient discomfort. Fifty patients who needed a mucogingival surgery requiring gingival graft harvesting were enrolled and randomly assigned to one of five groups: (1) a control group in which only sutures were applied; (2) a cyanoacrylate group; (3) a periodontal dressing material group; (4) a hemostatic gelatin sponge group; and (5) a group in which the gelatin sponge and cyanoacrylate were combined. In the 2 weeks following the procedures, the perception of pain, healing, consumption of drugs, and willingness to repeat the procedure were recorded through a visual analog scale (VAS) by patients.

This clinical investigation was performed to determine the efficacy of cyanoacrylate tissue adhesive to enhance soft and hard tissue healing of extraction wounds requiring a regenerative effort. Fourteen patients requiring a total of 25 tooth extractions were selected. Twenty sockets were treated with cyanoacrylate tissue adhesive over an exposed collagen barrier membrane without altering the mucogingival junction, while live extraction sockets were allowed to heal by the secondary healing intention as well but without tissue adhesive application.

Methods: Forty-five patients were included in three study groups: where stabilization was achieved with conventional techniques, cyanoacrylate or microsurgery. In the conventional group, standardized 5-0 sutures were used. In the micro-surgery group, grafts were stabilized with 7-0 sutures and loupe. In the third group, the graft was stabilized with cyanoacrylate. Keratinized tissue width, graft area, gingival recession were calculated by a specific software on standard photographs at baseline, 1-, 3-, 6-month follow-ups. Duration of surgery was also recorded. Pain in recipient and donor sites was assessed using visual analog scale within the first postoperative week.
Results: Change in keratinized tissue width was similar in the study groups at all times. Graft shrinkage was significantly less (p<0.05) in the cyanoacrylate group than the other groups, whereas those in the conventional and microsurgery group were similar. Significantly less pain in the recipient site was reported by the patients in the cyanoacrylate group(p<0.05). Duration of surgery was significantly less in the cyanoacrylate group than the other groups (p<0.05).
Conclusions: Less graft shrinkage in the free gingival graft, together with shorter surgery time and less pain in the recipient site obtained in the cyanoacrylate group, suggest that cyanoacrylate may be considered as an alternative for stabilization of free gingival grafts.

Abstract
Objectives: The aim of this study was to compare the effects of a hemostatic collagen sponge and a collagen sponge sealed with a bio-adhesive material on the palatal donor sites with the purpose of minimizing postoperative pain after epithelialized gingival graft (EGG) harvesting. Material and methods The present study consisted of 44 EGGs harvested in 44 patients. In the control group, a hemostatic collagen sponge was applied over the palatal wound, while the test group was treated with additional cyanoacrylate. Patients were observed for 14 days, evaluating the pain level by using the visual analogic scale. The consumption of analgesic during the postoperative period, the willingness for retreatment and the characteristic of the graft were also analyzed.
Results: Statistically significant differences in pain perception were found between test and control groups in each of the studied days (p < 0.01). Analgesic consumption was lower in the test group (p < 0.01). Graft width < 14 mm was found to be associated with lower discomfort (p < 0.01).
Conclusions: Adding an additional layer of cyanoacrylate over a hemostatic collagen sponge on the palatal wound following EGG harvesting was found to be successful in minimizing the postoperative discomfort and the need for analgesics. Clinical relevance Postoperative pain after palatal tissue harvesting can be successfully minimized if the donor site open wound is protected with an external layer of cyanoacrylate over a collagen sponge.

The application of cyanoacrylate after NSPT in this pilot study resulted in a clinically significant reduction of BOP (p=0.017*). Sixteen patients (69.5%) found the application of the adhesive highly acceptable. The changes in CAL and PD as well as the decrease in teeth sensitivity at 6-8 weeks following NSPT, was not found to be statistically significant.

]]>For many years researchers have been investigating the uses of cyanoacrylates in dentistry. In the 1960s, Dr. S.N. Bhaskar had several articles published discussing cyanoacrylates as effective periodontal dressings, and in April 1973, an article was published in the Journal of American Medical Association (Dermatology) discussing cyanoacrylates as superior extra-oral wound dressings.
