Objectives
To compare 3 mouthwashes: 0.20% chlorhexidine (CHX) with Anti‐Discoloration System (ADS), 0.20% CHX and 0.12% CHX with 0.05% cetylpyridinium chloride (CPC), in terms of reduction of plaque and gingival bleeding and side effects.
Methods
Mild gingivitis patients were randomly divided into three Groups: they underwent professional oral hygiene and received instructions: oral rinse with 10 mL for 1', twice a day, 30' after tooth brushing, for 14 days. Primary outcomes were plaque and gingival bleeding, assessed with Plaque Control Record and Gingival Bleeding Index. Feedback questionnaire and spectrophotometer evaluated secondary outcomes: adverse events. Timing of the study was T0 (baseline), T1 (professional oral hygiene) and T2 (14th day after mouthwash use).
Results
Sixty‐six patients were recruited, two patients dropped out, and 64 patients completed the study. PCR T1‐T2 mean variation was 30.67 (SD = 15.22; 95% CI 23.55 to 37.80; P = 0.000), 19.93 (SD = 11.03; 95% CI 14.90 to 24.95; P = 0.000) and 16.24 (SD = 15.35; 95% CI 9.60 to 22.88; P = 0.000) respectively in Groups 0.2% CHX + ADS, 0.2% CHX and 0.12% CHX + CPC. GBI mean variation (T0‐T2) was −9.82 (SD = 9.27; 95% CI −5.48 to 14.16; P = 0.000), −19.31 (SD = 11.33; 95% CI −14.15 to −24.47; P = 0.000) and −21.13 (SD = 12.56; 95% CI −15.70 to −26.56; P = 0.000) respectively in Groups 0.2% CHX + ADS, 0.2% CHX and 0.12% CHX + CPC. Statistical significance was found in lower efficacy of 0.2% CHX + ADS Group. Patients tolerated 0.12% CHX + CPC mouthwash better in bleeding perception (95.5%; P = 0.046), burning sensation (13.6%; P = 0.006), and mouthwash taste (100%; P = 0.000). Results on staining were no statistically significant (P = 0.106).
Conclusions
Addition of CPC allows reduction of CHX percentage in mouthwash formulation while keeping equal efficacy and less side effects. ADS addition decreases CHX efficacy in reducing plaque and bleeding, while resulting more tolerated than CHX.
(1) Background: Severe acute respiratory syndrome Coronavirus-2 (SARS-CoV-2) emerged in Wuhan, China, in late 2019. The development of effective and safe vaccines against SARS-CoV-2 has been extremely fast. The list of orofacial adverse effects of BNT162b2 and mRNA-1273 vaccines based on the clinical trials are reported to be rare. The aim of this study was to investigate the facial and oral manifestations of COVID-19 vaccination using a survey-based study. (2) Methods: The questionnaire was developed using Google Forms and sent anonymously to a total of 700 subjects (medical personnel) in Poland, Italy, and other EU countries. (3) Results: 223 people answered the questionnaire, mainly vaccinated with BNT162b2. Only 3.1% and 5.4% experienced oral and facial symptoms, respectively. General diseases presence and age have significant influence on the probability of oral symptoms occurrence after the second dose. Facial symptoms are correlated with general disease; autoimmune pathologies and age, at first and second dose, respectively. Gender, smoking and regular medication intake have significant influence on the probability of taking an absence day. Gender, age, and smoking have a significant influence on the duration of symptoms after second dose. (4) Conclusions: Based on the results of this preliminary survey, there is no observed significant correlation between vaccine administration for COVID-19 and facial and oral manifestations.
Background
Orthodontic retention aims to maintain optimal teeth positions after active treatment. The stability is affected by numerous factors, including patients’ individual features, thus retention should be adjusted in the most optimal way. Bonding a retainer makes retention less dependent on patient’s compliance.
Questions arise
What wire or fiber splint type provides the best treatment stability? What materials should be used to bond the wire or fiber splint? Should be the bonding procedure be direct or indirect? The aim of the study is to assess and synthesize available controlled trials investigating failures of fixed retainers.
Methods
Literature searches of free text and MeSH terms were performed in Scopus, Web of Science, Embase and PubMed Central in order to find studies, referring to failures of fixed retention (12th February 2021). The keywords were: (“orthodontic retainers AND failure AND wire”). The framework of this systematic review according to PICO was: Population: orthodontic patients; Intervention: fixed orthodontic retainer bonding; Comparison: Different protocols of fixed orthodontic retention applied; Outcomes: failure rate, survival rate. Three different specific scales from the Cochrane Collaboration Handbook were used, according to each study type. Additionally, a meta-analysis was conducted to compare the effectiveness of retention using fiber reinforced composite and multistranded steel wire.
Results
The search identified 177 potential articles: 114 from PubMed, 41 from Scopus, 20 from Web of Science and 2 from Embase. After excluding studies inconsistent with selection criteria, 21 studies were included and subjected to qualitative analysis. The main outcome investigated was failure rate. This systematic review has some potential limitations due to the heterogeneity of design between included studies.
Conclusions
No retainer is proved to guarantee a perfect stability of dental alignment. The retainer should be bonded to all adherent teeth, preferably with additional use of bonding resin. No wire or fiber splint present superior characteristics concerning failure rate. Fiber reinforced composite retention is more sensitive to operator skills, and with imperfect bonding technique, failure rate is much higher. During the first 6 months after bonding retainer the patient should be under frequent control. The study protocol was registered in PROSPERO database with the number CRD42021233406.
Background: Extracellular matrix metalloproteinases (MMPs) play a pivotal role in the damage to the periodontal tissue in patients with periodontitis. Scaling and root planning (SRP) attempt to control the plaque amount and consequentially reduce the bacterial load. Non-surgical periodontal treatment could be integrated with drug therapy and physiotherapy procedures such as ozone therapy. The aim of this study was to evaluate in a cohort of patients with a diagnosis of periodontitis: (1) the efficacy of non-surgical periodontal therapy assisted by the use of ozonated olive oil-based mouthwash on salivary metalloproteinase (MMP-8) and (2) the reduction of periodontal indices. Methods: Ninety-six subjects with a diagnosis of periodontitis were enrolled in this study and randomly assigned to the study group (SRP + mouthwash) or control group (SRP). The study duration was 3 months. Data on MMP-8, plaque index (PI), bleeding on probing (BoP) and probing pocket depth (PPD) were recorded at T0, T1 (14 days), T2 (1 month) and T3 (6 months). Group differences were assessed using Student’s t-test for independent samples. Results: A significant improvement in PI, BoP, PPD and salivary MMP-8 levels was observed in both groups. An analysis of differences in relative changes of indices revealed the efficacy of ozonated olive oil in decreasing MMP-8 level. Simultaneously, it slowed the decrease of BoP index. Conclusions: Scaling and root plaining with the aid of ozonated olive oil mouthwash were found to be more effective on salivary MMP-8 reduction than scaling and root plaining alone.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
