SUMMARY This prospective randomized clinical trial evaluated tooth sensitivity and patient satisfaction after the provision of partial ceramic restorations bonded using immediate (IDS) or delayed dentin sealing (DDS) on vital molar teeth through a within-subject comparison study. Between December 2013 and May 2016, a total of 30 patients (13 women, 17 men; mean age, 54 years old) received two lithium disilicate ceramic (IPS-e.max press, Ivoclar Vivadent) partial restorations on vital first or second molar teeth (N=60). The two teeth randomly received either IDS (test group, n=30) or DDS (control group, n=30). Partial preparations were performed on all teeth and directly after tooth preparation. IDS was achieved using self-etch adhesive (Clearfil SE Primer and Adhesive, Kuraray) followed by the application of flowable resin (Clearfil Majesty Flow, Kuraray). Partial ceramic restorations were bonded (Variolink Ultra, Ivoclar Vivadent) two weeks after preparation. The teeth were evaluated preoperatively and at one week, three months, and 12 months postoperatively using a cold test and a questionnaire for perceived tooth sensitivity. Patient satisfaction was evaluated using a visual analog scale (VAS). Data were analyzed using McNemar, chi-squared, and Wilcoxon signed rank tests (α=0.01). There was no significant difference in patient-reported tooth sensitivity between the preoperative phase and all other time points (p>0.01). There was also no significant difference between IDS and DDS (p>0.01) for all items on the questionnaire. VAS scores did not differ significantly between the IDS and DDS groups for all items in the questionnaire at all time points (p>0.01). No tooth sensitivity change was noticed with the application of partial ceramic indirect restorations. This clinical study could not confirm that IDS is more advantageous than DDS in terms of tooth sensitivity and patient satisfaction at 1 year of clinical service of partial ceramic restorations.

SUMMARY Objectives: It has been reported that bleaching generates an increase in the activity of osteoclasts in vitro. We quantified the RANK-L and IL-1β biomarkers in a double-blind, randomized clinical trial evaluating the in vivo effect of hydrogen peroxide (35%) and peroxide carbamide (37%) six months after whitening. Methods and Materials: Fifty volunteers participated, each with color change in a nonvital tooth. Fifty teeth were randomly divided into two groups (n=25), and the teeth were bleached using either 35% hydrogen peroxide (G1) or 37% carbamide peroxide (G2). Intracoronal bleaching was carried out by a technical “walking bleach” over four sessions. Gingival crevicular fluid samples were collected and used to quantify the IL-1β and RANK-L secreted levels. Samples of six periodontal sites (three vestibular and three palatal) were collected for up to six months (at the beginning of the study [baseline] and at one week, one month, and six months posttreatment). The color change was visually monitored using the Vita Bleached Guide (ΔSGU). Results: Comparing each time to baseline assessment, a significant increase in the levels of IL-1β and RANK-L across time points was detected (p<0.05). The color change was 4 in G1 and G2, and a statistically significant difference (p<0.05) was found at the month time point between the groups. Using the Spearman test, a strong correlation (>0.8) between the IL-1β and RANK-L levels in both groups at all time points was detected. Conclusions: Nonvital bleaching using a technical walking bleach induces an increase in the IL-1β and RANKL production in periodontal tissues, which persists for six months after treatment. Both biomarkers were highly correlated in both groups and at all time points.

Abstract This clinical trial evaluated the effect of the coadministration of ibuprofen/caffeine on bleaching-induced tooth sensitivity (TS). A triple-blind, parallel-design, randomized clinical trial was conducted on 84 patients who received ibuprofen/caffeine or placebo capsules. The drugs were administered for 48 hours, starting 1 hour before the in-office bleaching. Two bleaching sessions were performed with 35% hydrogen peroxide gel with 1-week interval. TS was recorded up to 48 hours after dental bleaching with a 0-10 visual analogic scale (VAS) and a 5-point numeric rating scale (NRS). The color was evaluated with VITA Classical and VITA Bleachedguide scales (ΔSGU) and VITA Easyshade spectrophotometer (ΔE*ab and ΔE00). The absolute risk of TS in both groups was evaluated using Fischer's exact test. Comparisons of the TS intensity (NRS and VAS data) were performed by using the Mann-Whitney test and a two-way repeated measures ANOVA, respectively. The color alteration between the groups was compared with the Student's t test. The significance level was 5%. There was no statistically significant difference between the groups for the absolute risk of TS (p = 1.00) or for the intensity of TS (p > 0.05). A bleaching of approximately 7 shade guide units was observed on the Vita Classical and Vita Bleachedguide scales, with no statistical difference between the groups. It was concluded that coadministration of ibuprofen and caffeine did not reduce the absolute risk or intensity of TS and did not interfere with the efficacy of dental bleaching.

Twenty-four patients with displaced ankle fractures awaiting surgery were randomized to a study (n = 11) or a control group (n = 13). In the study group, patients had a pulsatile cold compression (PCC) device applied to their ankle, and remained at bed rest with the extremity elevated while awaiting surgery. In the control group patients remained in a posterior molded splint instead of the PCC device. Baseline circumferential measurements of the ankle were obtained, followed by measurements at 24-hour increments to evaluate edema resolution. In addition, patient satisfaction with use of the PCC device was evaluated with a scale ranging from 1 to 4. The median decrease of circumference in the study group compared to the control group was 0.5 cm vs. 0.1 cm at 24 hours (p=0.005), 0.9 cm vs. 0.4 cm at 48 hours (p<0.001), and 1.2 cm vs. 0.5 cm at 72 hours (p=0.009). The ratio of the decrease in circumference relative to the circumference of the normal ankle was significantly higher in the PCC group compared to the control group at all time points. All patients in the PCC group were satisfied with the device (median satisfaction score = 4). The PCC device was well tolerated and resulted in a significantly greater reduction of ankle circumference at 24, 48, and 72 hours after its application, compared to splinting and elevation alone. The PCC device facilitates edema resolution following ankle fractures.

Background: The purposes of this randomized clinical trial study was to compare the immediate loading of dental implants while employing digital workflow and conventional implants in terms of the success rate, marginal bone level, and patient satisfaction. Methods: Fifty patients who had edentulous area on the mandibular premolar or molar area were included in the study. Twenty-five patients were assigned to immediate loading implant treatment using the digital technique and 25 patients were assigned to conventional loading implant treatment. In the first group, the patients were received digital impression (Cerec Omnicam, Dentsply Sirona®, York, PA, USA), designed, producing zirconia crown, and inserted on the same surgery day. The second group, after a healing period of three months, was received analog impression following conventional impression for the zirconia crown. Clinical outcome and radiographic bone level were evaluated after three, six, and 12 months. Patient satisfaction was measured at 12 months after inserting the implant. Results: There was no implants and protheses failure in both groups. The mean resonance frequency analysis values at the day of surgery were 78.26 ± 4.09 in immediate loading using the digital group (ILD) and 73.74 ± 5.14 in the conventional loading group (CL), respectively. Insertion torque values at the day of surgery were 36.60 ± 12.64 in ILD and 38.8 ± 12.19 CL, respectively. The marginal bone level in CL at three, six, and 12 months were 0.14 ± 0.28 mm, 0.18 ± 0.30 mm, and 0.17 ± 0.29 mm, respectively, while in ILD at three, six, and 12 months were 0.18 ± 0.33 mm and 0.16 ± 0.27 mm and 0.15 ± 0.31, respectively. There was no statistically significant difference between the two groups. Only one question in patient satisfaction’s questionnaire was “Now, can your dental implant and crown be used well?” had been significantly different in favor to the conventional group. Conclusion: Within the limitation of this study, it may be concluded that, after one-year follow up, there were no statistically significant differences between the immediate loading of dental implants employed from the digital workflow and conventional implant treatment technique in the success rate and marginal bone level. In patient satisfaction, there was only statistic significant difference in question related to implant prosthetic function in favor of the CL group, whereas the question concerning speaking, cleansing, price, and expectation displayed no difference.

BACKGROUND & OBJECTIVES: Esophagogastroduodenoscopy is a valuable diagnostic method for the treatment of various diseases that has found a wonderful application in recent years. Yet, controlling patients’ pain and nausea is a fundamental factor to increase patient satisfaction, reduce patients’ discomfort, and increase the patient’s cooperation. Therefore, this study aimed to assess the efficacy of Eutectic Mixture of Local Anesthesia (EMLA) cream and gel, as a topical pharyngeal anesthetic on patients’ pharyngeal pain, nausea/vomiting, and satisfaction, in comparison with lidocaine gel and spray and placebo.METHODS: This double-blind randomized clinical trial was conducted to assess patient satisfaction, nausea/vomiting, throat and pharyngeal pain during and after endoscopy by different methods of local anesthesia. Thus, 150 patients were randomly divided into 5 groups of 30 receiving placebo, lidocaine gel, lidocaine spray, EMLA gel and cream 5 to 10 minutes before endoscopy. Then patient satisfaction (measured by GHAA-9 questionnaire), pain or discomfort in the throat, and nausea/vomiting were evaluated half an hour after endoscopy.RESULTS: Patient satisfaction score was not statistically different between the test groups (P>0.05), but the throat pain and discomfort and nausea/vomiting during and after endoscopy was statistically different between groups (P<0.05) and the lowest nausea/vomiting was in the group using EMLA cream.CONCLUSION: Different methods of throat anesthesia had no significant difference on patient satisfaction but EMLA cream and gel caused less nausea/vomiting than lidocaine gel or spray during and after endoscopy.

AIM: The aim of the study was to assess the difference between patient satisfaction and bone height changes of mini-implant supported overdentures in comparison with conventional implant after bone expansion technique. METHODS: This randomized clinical trial contains 36 edentulous participants with thin mandibular ridges randomly divided to receive 2 mini-implants, or 2 conventional implants after ridge splitting, both treatments were done in the inter-forminal area of the anterior mandible. Then, the patients received mandibular overdentures with ball and socket attachments. At base line, after 6 and 12 months of loading the implants, patients’ satisfaction was evaluated using visual analog scale, in addition to bone height changes using Soredex DIGORA Optime Classic software. RESULTS: There was statistically significant difference in the overall satisfaction between the mini-implants and the conventional implants group; the amount of bone height changes in the mini-implant group was statistically significant less than the conventional implant group at base line, 6 and 12 months. CONCLUSION: Treatment with two mini-implants provides high level of satisfaction and less bone height changes in a follow-up period of 12 months in comparison to conventional implants after ridge expansion.

Clinical Relevance Although color change was slightly lower in a 3-week 30-minutes/day protocol, than in the 120-minute protocol, this could be compensated by an extra week of bleaching. The advantage of the shorter protocol is the reduced daily application, making the procedure more comfortable for the patients. SUMMARY Objective: Compare the risk/intensity of tooth sensitivity (TS) and color change of a 30-minute vs. the recommended 120-minute application time of 4% hydrogen peroxide (HP) for at-home bleaching. Methods: A single-blind, parallel, randomized clinical trial was conducted with 92 adult patients with caries and restoration-free anterior teeth A2 or darker, randomly allocated to two groups. Bleaching trays containing 4% HP were used for three-weeks. A four-week regimen was also offered to the patients for the 30-min group after the end of the 3-week protocol. The color change was assessed with the Vita Classical (VITA Zahnfabrik, Bad Säckingen, Germany) and Vita Bleachedguide shade guides (VITA Zahnfabrik) and the Vita Easyshade spectrophotometer (VITA Zahnfabrik) at baseline, weekly, and 30 days after the bleaching. The absolute risk and the intensity of TS were assessed daily using the 0-10 visual analogue scale (VAS) and 5-point Numerical Rating Scale (NRS) scale, and patient satisfaction was recorded with a Likert 0-7 scale. Risk of TS (Fisher’s test), intensity of TS in NRS scale (Mann-Whitney test), VAS scale (t-test), and a color change (t-test) were compared. Results: The 30-minute group saw color change of around 1 SGU inferior to the 120-minute group in all-time assessments (p&lt;0.05). After an extra week of bleaching, mean color change was similar (p&gt;0.05). Patient satisfaction was high for both groups (p&gt;0.05). Conclusions: A four-week protocol of at-home dental bleaching with 4% HP for 30 minutes/day whitened teeth similarly to the 120 minutes/day protocol, with low intensity of dental sensitivity and high patient satisfaction.

Abstract Objectives Injection of a topical anaesthetic has been proved to be helpful with reducing pain after laparoscopic herniorrhaphy. We aimed to assess the effect of bupivacaine lavage on postoperative pain and compare it with diclofenac suppository. In this randomized clinical trial, 60 patients—scheduled for laparoscopic herniorrhaphy—were enrolled and randomized into three groups of 20 each, including diclofenac suppository, bupivacaine lavage, and normal saline as a placebo.The patients were investigated for postoperative pain scores, vomiting, nausea, morphine request, and duration of hospitalization. Results In the bupivacaine group, pain levels in recovery room, 4, 8 and 12 h after surgery, were significantly lower than diclofenac group; at time points of 16, 20 and 24 h after surgery, difference between two groups was not significant. Regarding vomiting and nausea, at time points of 1 and 3 h after surgery, results show no significant difference between the groups. Incident of infection, 1 h and 1 week after the surgery, was not significantly different among the groups. Duration of hospitalization in the bupivacaine group was much lower than the diclofenac group. Based on our results, use of the bupivacaine lavage can reduce postoperative pain in patients undergoing laparoscopic herniorrhaphy.

Background: The effectiveness of different acellular dermal matrices (ADM) used for implant-based reconstruction immediately following mastectomy is an important clinical question. A prospective randomized clinical trial was performed to evaluate the superiority of DermACELL over Alloderm-RTU in reducing drain duration. Methods: Patients undergoing mastectomy with subpectoral immediate and permanent implant-based breast reconstruction were randomized to Alloderm-RTU or DermACELL. The primary outcome was seroma formation, measured by the duration of postoperative drain placement. Secondary outcomes included: post drain removal seroma aspiration, infection, redbreast syndrome, wound dehiscence, loss of the implant, and unplanned return to the operating room. Results: 62 patients were randomized for 81 mastectomies (41 Alloderm-RTU, 40 DermACELL). Baseline characteristics were similar. There was no statistically significant difference in mean drain duration (p = 0.16), with a trend towards longer duration in the Alloderm-RTU group (1.6 days; 95%CI, 0.7 to 3.9). The overall rate of minor and major complications were statistically similar between the two groups; although patients with Alloderm-RTU had 3 times as many infections requiring antibiotics (7.9% vs. 2.5%) with a risk difference of 5.4 (95%CI −4.5 to 15.2), and twice as many unplanned returns to the operating room (15.8% vs. 7.5%) with a risk difference of 8.3 (95% CI −5.9 to 22.5) as DermACELL. Conclusion: This is the first prospective randomized clinical trial comparing the two most commonly used human-derived ADMs. There was no statistically significant difference in drain duration, minor, or major complications between DermACELL over Alloderm-RTU in immediate subpectoral permanent implant-based breast reconstruction post-mastectomy.
