Özet

Objective: The aim of this study was to compare the inflammatory effects of conventional and laser soldering methods on

periodontal tissues in orthodontics.

Materials and Method: Forty specimens were acquired from 10 patients whose treatment plan consisted of extraction of 4 first

premolars. Before performing the extractions, a transpalatal arch (TPA) for the upper first molars and a lingual arch for the lower

first molars were placed for anchorage purposes. Upper left and lower right first molar bands were soldered using the laser

welding (LW) technique, and upper right and lower left first molar bands were soldered using the conventional silver soldering

technique (CSS). Gingival crevicular fluid (GCF) analysis was used for determining the effects of welding procedures on

periodontal tissues. All variables were analyzed by nonparametric tests.

Results: Myeloperoxidase levels ranged between 2.46 and 3.56 for the CSS group and between 2.20 and 3.39 for the LW group;

nitric oxide levels ranged between 4.92 and 7.13 for the CSS group and between 4.39 and 6.78 for the LW group. Both levels

showed the highest level on the seventh day. Plaque index and gingival index scores ranged between 0 and 1 for all specimens.

Bleeding on probing levels ranged between 45% and 75% and between 60% and 75% for the CSS group and LW group,

respectively.

Conclusion: There was no significant difference between laser welding and conventional soldering methods in terms of

periodontal tissue response.
