[Comparative assessment of the absorbency of wound dressings used in the removal of third molars of the lower jaw].

OBJECTIVE

The aim of the study was to evaluate the absorption capacity of various wound dressings used in the management of the recess of the removed third molar of the mandible.

MATERIALS AND

METHODS

A comparative assessment of the absorption capacity of YT, KG and AK was carried out. 10 samples of each wound dressing were immersed in four solutions (distilled water, saline, oral fluid, simulated exudate) for 72 hours; then the absorption capacity was calculated, statistical processing was performed using the Mann-Whitney U-test.Materials and methods: A comparative assessment of the absorption capacity of iodoform turunda, collagen-based and calcium alginate-based dressings was carried out. 10 samples of each wound dressing were immersed in four solutions (distilled water, saline, oral fluid, simulated exudate) for 72 hours; then the absorption capacity was calculated, statistical processing was performed using the Mann-Whitney U-test.

RESULTS

In saline solution, the absorption capacity was: YT 6.43 ml/g, KG 11 ml/g (p≤0.05), AK 17.06 ml/g (p≤0.05); in distilled water, YT corresponded to 7.2 ml/g, KG 8.13 ml/g (p>0.05), in AK 15.8 ml/g (p≤0.05). In the oral fluid, the absorption capacity of wound dressings corresponded to 9.0 ml/g in YT, 15, 3 ml/g in KG (p >0.05), and 16.8 ml/g in AK (p≤0.05). In the exudate model, the absorption capacity of YT is 13.5 ml/g, KG is 8.3 ml/g (p >0.05), AK is 18.0 ml/g (p≤0.05). The intragroup values of YT and KG differed depending on the type of liquid. When assessing the absorption capacity of AK in different media, there were no statistically significant differences between the indicators (p>0.05 in all intragroup comparisons).

CONCLUSION

The alginate dressing has significantly relatively high absorption properties, demonstrating functional stability in various environments, which makes it possible to recommend it as a reliable alternative to other wound dressings after complex removal of the third molar of the mandible and opens up prospects for evaluating its clinical effectiveness.
