Objective. The aim of this clinical study was to evaluate the effectiveness of a whitening toothpaste containing 3% carbamide peroxide and lactoperoxidase. Materials and methods. Participants were instructed to brush their teeth using an enzymatic-activated dentifrice following a particular procedure for three weeks. Color was recorded before and after treatment using a VITA Easyshade spectrophotometer. Differences in L ∗ (tooth color lightness), a ∗ (displacement along the red-green axis), and b ∗ (displacement along the yellow-blue axis) were measured before and after treatment using the paired t and the Wilcoxon signed-rank tests. Color changes (ΔE) were calculated using the obtained measurements. Results. Thirty-four volunteers were included. ΔE was 4.03. For the set of 348 teeth, a greater tendency towards green (lower a ∗ ) and blue (lower b ∗ ) was observed ( p  < 0.05). There were no significant differences in lightness after treatment. Mandibular central incisors showed a greater tendency towards green (lower a ∗ ) and blue (lower b ∗ ). Bleaching effectiveness was observed in both the upper and lower central incisors and in the lateral mandibular incisors. Conclusion. Based on these results, it may be concluded that brushing with an enzymatic-activated dentifrice is effective for whitening teeth.

OBJECTIVEIn Gamma Knife radiosurgery (GKS) for arteriovenous malformations (AVMs), CT angiography (CTA), MRI, and digital subtraction angiography (DSA) are generally used to define the nidus. Although the AVM angioarchitecture can be visualized with superior resolution using rotational angiography (RA), the efficacy of integrating RA into the GKS treatment planning process has not been elucidated.METHODSUsing data collected from 25 consecutive patients with AVMs who were treated with GKS at the authors’ institution, two neurosurgeons independently created treatment plans for each patient before and after RA integration. For all patients, MR angiography, contrasted T1 imaging, CTA, DSA, and RA were performed before treatment. The prescription isodose volume before (PIVB) and after (PIVA) RA integration was measured. For reference purposes, a reference target volume (RTV) for each nidus was determined by two other physicians independent of the planning surgeons, and the RTV covered by the PIV (RTVPIV) was established. The undertreated volume ratio (UVR), overtreated volume ratio (OVR), and Paddick’s conformal index (CI), which were calculated as RTVPIV/RTV, RTVPIV/PIV, and (RTVPIV)2/(RTV × PIV), respectively, were measured by each neurosurgeon before and after RA integration, and the surgeons’ values at each point were averaged. Wilcoxon signed-rank tests were used to compare the values obtained before and after RA integration. The percentage change from before to after RA integration was calculated for the average UVR (%ΔUVRave), OVR (%ΔOVRave), and CI (%ΔCIave) in each patient, as ([value after RA integration]/[value before RA integration] − 1) × 100. The relationships between prior histories and these percentage change values were examined using Wilcoxon signed-rank tests.RESULTSThe average values obtained by the two surgeons for the median UVR, OVR, and CI were 0.854, 0.445, and 0.367 before RA integration and 0.882, 0.478, and 0.463 after RA integration, respectively. All variables significantly improved after compared with before RA integration (UVR, p = 0.009; OVR, p < 0.001; CI, p < 0.001). Prior hemorrhage was significantly associated with larger %ΔOVRave (median 20.8% vs 7.2%; p = 0.023) and %ΔCIave (median 33.9% vs 13.8%; p = 0.014), but not %ΔUVRave (median 4.7% vs 4.0%; p = 0.449).CONCLUSIONSIntegrating RA into GKS treatment planning may permit better dose planning owing to clearer visualization of the nidus and, as such, may reduce undertreatment and waste irradiation. Further studies examining whether the observed RA-related improvement in dose planning also improves the radiosurgical outcome are needed.

Background: Comprehensive medication reviews (CMRs) provide opportunities for pharmacists to perform clinical services to their patients. However, pharmacists are often not able to perform CMRs due to time constraints. Studies have shown that incorporating support staff into the CMR workflow may lead to increases in the completion of CMRs. Objective: The primary objective was to examine the change in the number of CMRs completed at the pharmacy after a new strategy was implemented to perform and prepare for CMRs. The secondary objective was to examine the changes in the revenue generated from CMRs. Methods: This study was a pre-post retrospective, observational study performed at an independent pharmacy. Data were collected and analyzed 10 months before and after implementation of a new strategy. The new strategy called for pharmacy interns to use a template for working up patients prior to CMRs. Wilcoxon signed-rank tests were run on IBM SPSS, Version 24.0, to determine the significance of the changes. Results that generated P values <.05 were considered statistically significant. Results: The total number of CMRs completed increased from 29 before the intervention to 158 after the intervention ( P = .009). The revenue generated from CMRs improved statistically ( P = .007). Conclusions: Implementing a strategic workflow that uses pharmacy interns and a patient workup template can significantly increase the number of CMRs completed in a community pharmacy. Appropriate delegation of such tasks may allow more time for pharmacists to deliver more CMRs. Additional benefits include increased compensation from delivering more CMRs.

Abstract There is a growing need for novel intervention for caregivers of family members with dementia. Improv for Care is a six-week program designed to teach improvisation (“improv”) skills to caregivers to practice flexible communication, build social support, and process the demands of caregiving through humor and play. This study aimed to examine changes in caregiver depression (Beck Depression Inventory-II), perception of burden (Zarit Burden Interview), qualitative experiences related to caregiving, and their cared-for person’s neuropsychiatric symptoms (Neuropsychiatric Inventory Questionnaire). Fifteen caregivers completed questionnaires before and after the Improv for Care program. Wilcoxon signed rank tests for related samples revealed significant declines in both caregivers’ depressive symptoms, Z = -2.64, p = .008, and sense of burden, Z = -2.16, p = .031, after completing the program. Caregivers reported that their loved ones’ neuropsychiatric symptoms increased during the course of the intervention, Z = -2.10, p = .036, though associated distress did not also increase, Z = -1.12, p = .265. Of the 15 caregivers, 12 completed follow up questionnaires three months after course completion, which showed that their post-intervention reduction in depressive symptoms remained stable, Z = -1.02, p = .306. The Improv for Care program shows promise as an intervention for caregivers to improve stress, mood, and coping skills.

Objective. The purpose of this study was to compare the color changes and microhardness of a nanocomposite after four bleaching regimens.Materials. Twenty-five specimens(n=25)were made with a nanocomposite resin (Filtek Supreme XT). The specimens were divided into five groups equally(n=5): bleaching groups and control group, as follows: G1: artificial saliva at37∘C; (control) G2: hydrogen peroxide (HP) at 7%; G3: hydrogen peroxide (HP) at 35%; G4: carbamide peroxide (CP) at 10%; G5: carbamide peroxide (CP) 35%. Color measurements were made with spectrophotometer using CIELAB color scale. The Vickers hardness (VHN) measurements were performed at the top surface. The data were analyzed with two-way Analysis of Variance.Results.ΔE and VHN mean values into the groups were not statistically different, however, the VHN mean values before and after storage and bleaching showed statistically significant differences.Conclusion. Nanocomposite samples showed no significant alteration (color and microhardness) after bleaching. Thus, no replacement of restorations is required after bleaching.

The aim of this study was to evaluate the effects of bleaching on color change of stained resin composites. Ninety disk-shaped specimens were prepared with 3 different composite materials (Estelite ∑ Quick, Premise, and Filtek Z350 XT). After stored in artificial saliva at 37°C for 24 hours in an incubator, the 30 specimens of each material were divided into 3 subgroups and immersed in either coffee, red wine, or artificial saliva (control) at 37°C. After 24 days, spectrophotometric measurement was performed. After the staining process, the bleaching agent (Opalescence, 10% carbamide peroxide) was applied to the surface of the specimens, 8 hours per day for 14 days. After the bleaching process, spectrophotometric measurement was performed. The color differences between specimens before and after bleaching were statistically significant (ΔE*ab>3.3) for all composites in the red wine staining. The highest-level color change after bleaching was observed for Filtek Z350 XT in red wine staining, while the least value was found in Estelite ∑ Quick in coffee staining. In summary, color changes of all red wine-stained composites after bleaching were noticeable and have higher level of color change than coffee-stained composites.

ABSTRACT Dentistry treatment is not only focused on restoring the function of mastication but also onthe aesthetic problem. Fluorosis is one of the aesthetic problems caused by excessive fluoride intakeduring email formation and produced color changes on the surface of the email. Fluorosis was notaffected by the aesthetics but also influenced the confidence of the patient. The Microabrasion techniqueis an option for fluorosis because it is conservative treatment with good results. A 20-year-old womanwho came to the Dental Conservation clinic complained that she wants to remove the brown color andwhite spots seen on the front teeth, which significantly interfere with her appearance. Based on clinicalexamination, many cavities were found in the back teeth of the upper and lower jaw. The results of thehistory and clinical study revealed that the patient had fluorosis in her teeth. Microabrasion was carriedout using Opalustre (ultradent). This material was applied to the tooth surface and rubbed using anapplicator (opal bristle) for 60 seconds. Then applied fluoride gel paste with finishing cup opal.Treatment results showed changes in tooth color, brown and white patches disappeared. Microabrasionis the first choice for aesthetic treatment in fluorosis and has shown satisfying results to restore thepatient's aesthetics problem. KEYWORDS: Fluorosis, microabrasion technique
