ABSTRACT
Objective To explore the effect of minimally invasive techniques for removing impacted wisdom teeth on local inflammation and pain. Methods A total of 110 patients with impacted wisdom teeth removed in our department from June 2016 to February 2018 were divided into observation group(55 cases,minimally invasive removal) and control group (55 cases, traditional chisel) according to the surgical method. The operative status, the inflammatory mediators and pain mediators in the gingival sulcus before and after the treatment, and the therapeutic effects of the two groups were compared. Results The operative time of the observation group was shorter than that of the control group,the intraoperative blood loss was less than that in the control group, the differences were significant(P ＜ 0. 05). The levels of PTX3, cells in the gingival sulcus adhesion of cytokine 1 (ICAM1),peroxidase (MPO),prostaglandin E2 (PGE2) levels,pain mediator 5-hydroxytryptamine(5-HT), calcitonin gene-related peptide(CGRP), substance P(SP), galanin(Gla) and adenosine triphosphate(ATP) in the observation group after treatment was lower than those in the control group, the differences were significant(P ＜ 0. 05); The degree of mouth opening restriction, facial swelling and visual analog scale score(VAS) in the observation group were lower than those in the control group, the differences were significant(P ＜ 0. 05). Conclusion Compared with traditional chisel in extraction of impacted wisdom teeth, the minimally invasive wisdom tooth extraction can relieve the inflammatory response and pain sensation of patients,and the clinical treatment effect is significant.
ABSTRACT
Objective To examine the effects of two different cold compress modes (continuous cold compress and intermittent cold compress) on the pain and swelling among patients receiving extraction of impacted tooth of mandibular. Methods From January 2016 to August 2016, 64 cases of adult patients with impacted mandibular impacted wisdom teeth and 24 h in the outpatient department of Oral and Maxillofacial Surgery of Affiliated Stomatological Hospital of Fujian Medical University were selected. They were randomly assigned to the control group and the experimental group (32 cases in each group) by random digital table. The participants in the control group received the usual care plus intermittent cold compress. The participants in the experimental group received the usual care plus continuous cold compress. And the treatment was continued for 24 hours. Outcomes including pain and skin temperature were measured in the intervention cycle, and the swelling was measured at baseline, 6 hour, 12 hours,18 hours, and 24 hours after the intervention. All the participants were asked to have further consultation at 7th days after the operation. Results At 6 hour, 12 hours,18 hours, and 24 hours, the pain of the experimental group was lower than the control group ,and there was significant difference (F=63.665-290.872, P<0.05 ). At 12 hours,18 hours, and 24 hours after the intervention ,number of the swelling grades (0-I-Ⅱ-III) in the control group was 16, 14, 2, 0 cases, 11, 13, 8, 0 cases, 11, 12, 8, 1 cases,number of the swelling grades (0-I-Ⅱ-III) in the experimental group was 27, 5, 0, 0 cases, 26, 6, 0, 0 cases, 26, 6, 0, 0 cases, and there was significant difference (Z=-2.968,-4.017,-4.052, P<0.05). A positive correlation between swelling grade and time (M2=45.22, P<0.05). At 6 hour, 12 hours,18 hours, and 24 hours , the skin temperature of the experimental group was lower than the control group, and there was significant difference (F=1 735.106-23 993.33, P<0.05). Conclusions This study showed that the continuous cold compress was more effective in reducing the pain and swelling among the patients receiving extraction of impacted tooth of mandibular. Compared with the intermittent cold compress, it suggested that continuous cold compress can be integrated into usual care to reduce the pain and swelling among the patients receiving extraction of impacted tooth of mandibular.
