Abstract:
Objective To study the clinical efficacy of Nd∶YAP laser in the treatment of acute localized pericardial periodontitis. Methods A total of 120 patients with acute localized pericardial periodontitis were randomly divided into 3 groups, including Nd∶YAP laser group, minocycline group and control group (iodine glycerol group). All patients were underwent pretreatment of intracrevicular washing with 3.0％hydrogen peroxide and normal saline alternately. After the pretreatment, the patients in the Nd∶YAP laser group were given 3 min local Nb:YAP laser irradiation (1 time/d for 3 times), in the minocycline group were injected with minocycline hydrochloride ointment (1 time), and in the control group were treated with 2％iodine glycerol (1 time/d for 4 times) in gingival sulcus. One day after the treatment, the gingival index (GI), pain visual score (VAS), and opening degree of all patients were recorded, and the therapeutic effect was observed 5 days after the treatment. Results Compared with the minocycline group and the control group (iodine glycerol group), the GI value and VAS value of the Nd∶YAP laser group decreased and the openmouthed size increased (all P<0.05). At 5 days after the treatment, the patients in the Nd∶YAP laser group and the minocycline group had significant improvement in local gingival sulcusinflammation, and the total effective rate was 90％and 85％, which was significantly better than the control group (all P<0.05) and no significant difference in efficacy between the two groups (P>0.05). Conclusions The Nd∶YAP laser treatment inacute wisdom tooth pericoronitis can significantly reduce pain and improve openmouthed size, and has a good clinical efficacy.
