Background:
When it comes to surgical site infection (SSI), it has been shown that two-thirds of wound infections starts around the incision line and the number is even greater in the presence of sutures. Therefore, a number of compounds have been used to coat the suture materials which tend to decrease the SSI some of which include ciprofloxacin,
Objective:
The objective of this study was to assess the antibacterial properties of neem oil-coated sutures in anaerobic culture media when compared to triclosan-coated sutures and uncoated sutures.
Materials and Methods:
The phosphate-buffered saline solution containing the plaque samples of the patients was transferred evenly onto the sterile agar media. Equal segments of 100% neem oil coated (Group 1), 50% neem oil coated (Group 2), triclosan-coated (Group 3), and uncoated (Group 4) sutures were placed on the agar plate. These were then incubated at 37°C for 24 h. The inhibition zone was calculated in mm by measuring of the zone of inhibition (ZOI) in terms of length, breadth, and area.
Results:
The results were calculated following the incubation. The mean length for 100% neem oil-coated suture was 2.61 mm ± 0.2 and for 50% neem oil-coated suture was 2.49 mm ± 0.24. The mean breadth for 100% neem oil-coated suture was 1.5 mm ± 0.41 and for 50% neem oil-coated suture the mean was 0.95 mm ± 0.58. The mean area for 100% neem oil-coated suture was 77 mm ± 32.9 and for 50% neem oil-coated suture was 16.8 mm ± 11.14. Triclosan and uncoated sutures did not show any ZOI.
Conclusion:
The 100% neem oil-coated sutures had the largest length, breadth, and area of ZOI in the anaerobic culture media, followed by 50% neem oil-coated sutures. Triclosan-coated and uncoated sutures did not show any ZOI. Therefore, neem oil-coated suture can be used in the overall healing and prevention of postoperative discomfort after oral surgical procedures.
