Throughout the history the most diverse suture material have been used for closing and suturing surgical wounds. The four basic features of suture material are described: knot safety, stretch capacity, tissue reactivity and wound safety. Tissue reaction, even the minimum one, which develops during the first to seven days after applying the suture in the tissue. The aim of this study was to investigate influence of a monofilament suture material (nylon) on the intensity of local tissue reaction in experimental conditions, and to compare it with the multifilament suture used in the routine practice of oral surgery (silk). This investigation is a prospective experimental study carried out on Wistar rats. The experiment included 30 animals, in which Black Silk (thickness 4-1) and Nylon (thickness 4-0) were applied in the upper and lower jaw, respectively. To monitor tissue reaction on different suture materials the following parameters were used: coagulum formation, presence of polymorp...

Sutures are medical devices used in surgery. They serve as tissues stabilizers in contact with or near to the surgical site without compromising the healing process. They must keep their physical properties for the necessary time, in particular tensile strength. In view of the wide variety of references offered by all specialtys combined, which supply sutures with all materials described, whose use is indicated for all surgical procedures. The objective of this work is to evaluate the tensile strength of absorbable and non-absorbable sutures for a period of 10 to 28 days under conditions simulated by the oral route. 5 sutures materials were tested with a metric diameter of 1.5 and 4.The tensile strength test was used according to the protocol of the European Pharmacopoeia (Eur.Ph.9.5). 5 fragments of each material were measured before and after their immersion in Artificial Saliva (AS). In AS, the Polypropylene suture significantly maintained (p = 5%) its tensile strength compared t...

The success of surgical procedures is strictly related to the biomechanical properties of the suture. Mechanical comparisons are scarcely reported in the literature, so the purpose of the present study was to evaluate and compare the mechanical behavior of different sutures commonly used in oral surgery in terms of traction resistance. Sutures made of eight different materials were analyzed: silk (S), polyglycolide-co-caprolactone (PGCL), polypropylene (PP), rapid polyglycolide (rPGA), standard polyglycolide (PGA), polyamide (PA), polyester (PE), and polyvinylidene fluoride (PVDF). For each material, three different sizes were tested: 3-0, 4-0, and 5-0. The breaking force of each suture was assessed with a uniaxial testing machine after being immersed in artificial saliva at 37 °C. The outcomes analyzed were the breaking force, the needle–thread detachment breaking-point and the node response after forward–reverse–forward (FRF) tying when subjected to a tensile force. The 3-0 rPGA p...

Background/Aim. Appropriate selection of suture materials is a crucial step in oral, maxillofacial and periodontal surgery for uneventful healing. We have scarcity of comprehensive studies comparing mechanical properties of commonly used suture material in oral surgery. The present in vitro study sought to evaluate the effect of saliva on the strength, elongation and stiffness of the commonly used suture material over a period of two weeks. Methods. Three suture materials, silk (SL), polyglactin 910 (PG) and polypropylene (PP), were used in 4?0 gauge. A total of 120 suture samples (40 from each material) were used for the investigation. Artificial saliva was mixed with human serum in 1:1 ratio and maintained at pH of 7.4 to 8.1 to simulate oral environment. All samples were tested at pre-immersion (baseline), as well as on the 3rd, 7th and 14th day in the post-immersion period. A universal testing machine was used to test the selected mechanical properties. The collected data were s...

Objectives: The present in vitro study sought to evaluate the effect of saliva on the tensile strength of the commonly used suture material over a period of two weeks. Three suture materials Silk (SL), polyglactin 910 (PG) and polypropylene (PP) were used in 4-0 gauge. Methods: A total of 120 suture samples (40 from each material) were used for the experiment. Artificial saliva was mixed with human serum in 1:1 to simulate oral environment. All samples were tested at preimmersion (baseline), 3rd, 7th and 14th day post-immersion period. Universal testing machine was used to test the selected mechanical properties. Results: The distribution of mean baseline tensile strength was significantly higher in PP group (P-value<0.001). Inter-group comparison revealed that PP group has maximum tensile strength when compared with PG and SL groups at all point of time. Intra-group comparison showed that all the three suture materials had significant difference in mechanical properties when pre...
Comparing Suture Strengths for Clinical Applications: A Novel In Vitro Study
Journal of …, 2009
Background: The purpose of this study was to compare the tensile strengths of commonly used sutures over a 2-week period under simulated oral conditions. Methods: Three suture materials (chromic gut [CG], polyglactin [PG], and polyglactin-fast absorbing [PG-FA]) were used in 4-0 and 5-0 gauges. After pretensioning, 252 suture samples (42 of each material and gauge) were used. A biologic simulation was created in vitro by mixing 9 ml sterile human saliva and human serum in a 1:1 ratio in a petri dish maintained at a pH of 7.4 to 8.1 at 37°C. All samples were tested preimmersion and 1 hour and 1, 3, 7, 10, and 14 days postimmersion. The tensile strength was assessed using a microtensile tester, and the maximum load required to cause suture breakage was determined. The point of breakage in the samples and the samples themselves were also assessed. Results: During the first 24 hours of immersion, all 4-0 and 5-0 samples of CG and PG maintained their initial level of tensile strength; PG-FA 5-0 decreased in strength, which was statistically significant (P = 0.001). Between days 1 and 3, the tensile strength of PG and PG-FA decreased significantly, with PG-FA 5-0 showing a greater and more precipitous decrease than PG-FA 4-0; the tensile strength of CG changed little during this time. After 7 days of immersion, PG 4-0 had significantly greater tensile strength than CG, and both were significantly greater than that of PG-FA. By day 10, CG and PG had statistically greater strength (P = 0.01) than PG-FA, and values were similar for the 4-0 and 5-0 gauge materials. All samples of PG-FA 5-0 and most samples of the PG-FA 4-0 exhibited 0.00 N strength (i.e., they had disintegrated) at the 10-and 14-day periods of evaluation. Conclusions: 4-0 sutures are stronger and have greater tensile strength than 5-0 sutures. CG seems to sustain its strength better than PG and PG-FA after 2 weeks. PG-FA may not be a desirable suture if tensile strength is required after 10 days. Appropriately designed clinical studies are necessary to confirm this finding in an in vivo environment.
Evaluation of the tissue reaction of five different suture materials in rabbit palatal mucosa
Journal of Ege University School of Dentistry, 2010
The objective of this study was to evaluate local tissue reactions at silk, chromic gut, polypropylene, polyester, and polyglactin 910 suture materials for intraoral applications. One hundred eighteen sutures were placed into the palatal mucosa of 26 male New Zealand rabbits so that each animal included all five biomaterials. The animals were fed a soft diet and decapitated 2, 4, or 8 days after suture placement. Soft tissue specimens including suture materials were prepared for light microscopy to determine the inflammatory zones including eosinophil infiltration on the suture tract. No significant differences were observed in the sutural zone diameter (Z1) between the suture materials at the 2nd day. At the 4th day, polypropylene and catgut had a lesser Z1 diameter compared to polyglactin 910. Dacron presented the widest mean Z1 diameter compared to polyglactin 910 (p<0.01), catgut (p<0.01), polypropylene (p<0.05) and silk (p<0.05) at the 8th day. On the day 8, the largest mean Z2 diameter was observed in dacron group compared to the mean Z2 values of catgut (p<0.05) and polyglactin 910 (p<0.01). Also the mean Z2 values of silk were significantly wider compared to polyglactin 910 (p<0.05). There was no difference between the eosinophil scores of the suture materials (p>0.05). Within the limitations of the present study, it may be said that silk and dakron sutures apparently induced more severe inflammatory reactions. When selecting a suture material for intraoral use the surgeons should take into consideration the tissue reaction caused by materials.
Tissue Reactions to Various Suture Materials Used in Oral Surgical Interventions
ISRN Dentistry, 2012
A variety of suture materials are available for primary wound closure following oral surgical procedures. The aim was to review the tissue reactions to the various suture materials used in oral surgical interventions. Databases were searched using the following keywords: cotton, nylon, polyglecaprone 25, polytetrafluoroethylene (ePTFE), Polyglactin 910, polyglycolic acid (PGA), polylactic acid, silk, surgery, suture, and tissue reaction. Articles published only in English language were included. Seventeen studies were included. Two studies reported that polyglecaprone 25 had positive effects on wound-healing as compared to silk. Six studies reported that silk elicits more intense tissue inflammatory response and delayed wound healing as compared to other suture materials (including ePTFE, polyglecaprone-25, PGA, and nylon). Polyglactin 910 sutures were associated with the development of stitch abscess in one clinical study. Eight studies reported that tissue reactions are minimal with nylon sutures. Tissue reactions to suture materials used for oral surgical interventions may vary depending on the surface properties and bacterial adherence properties of the material.
