Effect of Pharyngeal Pack on Postoperative Nausea and Throat Pain in Patients Undergoing Rhinoplasty

Objective: To evaluate the effect of pharyngeal pack on postoperative throat pain and nausea in rhinoplasty patients. Material and Methods: Twenty-eight patients were randomly selected and divided into two groups (n=14). The participants were randomly divided into two groups: G1 - the pharyngeal pack was used (Intervention group) and G2: not used (Control group). Both groups were anesthetized by the same protocol. Throat pain was measured by visual analog scale and nausea by presence / absence. Fischer's exact test, ANOVA, Friedman and Wilcoxon test were used. Results: There was no significant difference in mean pain and presence or absence of nausea between the two groups (p>0.05). But there was a significant difference in mean pain and the presence or absence of postoperative nausea with the intervals (p<0.05). Mean pain had a significant difference 2 hours postoperatively with other times, 6 hours postoperatively with 24 and 72 hours postoperatively, and 24 hours postoperatively with 72 hours (p<0.05). There was no significant difference in the presence or absence of postoperative nausea, between 2 hours and 6 hours postoperatively (p>0.05). The presence or absence of postoperative nausea had a significant difference between 2 hours postoperatively with 24 and 72 hours postoperatively and 6 hours postoperatively with 24 and 72 hours postoperatively (p<0.05). There was no significant difference in nausea between 24 hours and 72 hours postoperatively (p>0.05). Conclusion: None of the two groups were significantly superior in terms of reduction of pain and nausea, but because of the possible effectiveness of the pharyngeal pack in preventing aspiration of objects and tissues during the operation, the use of pharyngeal pack is recommended in patients.

Efect of Anaheal (Bromelain) Drug on the Periodontal Clinical Indices in Nonsurgical Periodontal Treatment of Patients with Chronic Periodontitis

Objective: To evaluate the effect of Anaheal (Bromelain) drug on the periodontal clinical indices in nonsurgical periodontal treatment of patients with chronic periodontitis. Material and Methods: In this double blind clinical trial, 80 patients with chronic moderate periodontitis and a healthy systemic status were chosen, and divided into two 40-subject groups. Thereafter, the standard treatment of periodontitis including scaling and root planning in one session by the unit operator was performed for all patients. Eventually, one group of the patients was administered Bromelain medication (500-mg capsule twice a day) one hour before food, while the other group was given placebo. Four and eight weeks after the treatment, the clinical periodontal indicators were measured and recorded in both groups. The data were assessed using descriptive statistics and analytical test methods (Mann-U-Whitney and Chi-square). P value less than 0.05 was considered statistically significant. Results: Gingival index, probing depth and plaque index before the treatment were similar in both groups (Anaheal and placebo). However, four and eight weeks after the treatment, the three studied indices were significantly lower in the Anaheal group as compared to the placebo (p<0.05). The index of bleeding on probing was also similar before the treatment and four weeks after the treatment in both groups. However, eight weeks after the treatment, this index was significantly lower in the Anaheal group as compared to the placebo group (p<0.05). Conclusion: Administration of oral Anaheal medication after nonsurgical periodontal treatments reduced all the clinical periodontal indices among patients with chronic periodontitis as compared to the control group. Therefore, it can be a suitable substitute for the common oral industrial antibiotics.

Effect of Sequential Use of 0. 2% Chlorhexidine Mouthwash and Listerine on Microbial Plaque Control

Objective: To evaluate the effects of combined and sequential consumption of chlorhexidine and listerine mouthwashes on plaque indices. Material and Methods: Sixteen dental students, both genders, were selected. After prophylaxis, four mouthwash regimens were used, such that in each period, mouthwash was used for 5 days and after each period there was 4 days of washing out. During the mouthwash period, the participants did not use any mechanical plaque control tool. The four regimens included: first regimen, first chlorhexidine then listerine; second regimen, listerine then chlorhexidine; third regimen, only listerine; fourth regimen, chlorhexidine alone. At the end of the period, individuals were evaluated for plaque indices and investigated for bleeding during probing using ANOVA variance analysis and post-hoc Tukey test. The level of significance was set at 5%. Results: Regimen 1 with a plaque mean of 0.55 ± 0.25 had significantly lower plaque than other regimens. The maximum rate of plaque was observed in regimen 3. Probing did not cause bleeding in any of the individuals who used the four mouthwash regimens. Conclusion: The use of 0.2% chlorhexidine and listerine has the highest effect on plaque reduction.
