ABSTRACT Objectives To evaluate tooth movements during maxillary arch expansion with clear aligner treatment. Materials and Methods The study group included 28 subjects (16 females, 12 males, mean age 31.9 ± 5.4 years) collected prospectively from January 2018 to May 2019. Inclusion criteria were European ancestry, posterior transverse discrepancy of 3–6 mm, permanent dentition stage, presence of second permanent molars, mild or moderate crowding, and good compliance with aligners. Treatment protocol included nonextraction strategies, application of Invisalign clear aligner system, and no auxiliaries other than Invisalign attachments. Linear and angular measurements were performed before treatment (T1), at the end of treatment (T2), and on final virtual models (T2 ClinCheck). A paired t-test was used to compare T2-T1 and T2-T2 ClinCheck changes. The level of significance was set at 5%. Results Statistically significant differences were found for all measurements, except for ones at the upper second molars. The greatest increase in maxillary width was detected at the upper first and second premolars: +3.5 mm for the first premolar and +3.8 mm for the second premolar at T2. Comparison of T2-T1 angular outcomes showed statistically significant changes in the inclinations of all teeth except for the second permanent molars. T2-T2 ClinCheck showed significant differences for both linear and angular measurements for maxillary canines, resulting in poor predictability. Conclusions Maxillary arch development revealed a progressive reduction of the expansion rate and buccal tipping in the anterior, lateral, and posterior regions, with the greatest net increase at the first and second premolars. Clinical attention should be paid to maxillary canine movements, and overcorrection should be planned for them during dentoalveolar expansion.

Abstract Introduction The rapid maxillary expansion (RME) reduces the risk of developing structural and functional disorders in the stomatognathic system. Objective To examine the effects of the RME as a treatment for the posterior crossbite, related with the electromyographic activity of the masticatory muscles and the TMJ noises in a population of children. Material and method 13 girls and 7 boys, regardless of the type of malocclusion, with a mean age of 9 years old (± 3), were treated with RME. The electrovibratography analyzed the TMJ noise, and the electromyography analyzed the masticatory muscles before treatment (T0) and after three months of a short-term follow-up (T1). The comparisons of the affected and unaffected sides by the crossbite were performed using Mann-Whitney’s test, and to compare data before and after treatment the Wilcoxon’s test was used (level of significance: 5%). Result No significant differences were found in the parameters of joint noise in comparison to the sides affected and unaffected by the crossbite, in both T0 and T1 (p>0.05); only the side without the crossbite observed decrease in the peak amplitude of the joint noises after treatment. In the static electromyographic analysis, inter-side differences were observed before and after treatment, since the deliberate unilateral chewing showed greater asymmetry activity in T0 for both sides, which has been corrected after treatment, improving the functional chewing. Conclusion The proposed treatment did not lead to the occurrence of joint noises and improved the functional pattern of electromyographic activity during chewing at the end of treatment.

Evidence regarding the caries-inhibiting effect of chlorhexidine varnish is inconclusive. This study investigated the caries-inhibiting effect of the varnish EC40 on pits and fissures of first permanent molars. A two-year randomized controlled trial was carried out among 461 six- to seven-year-old children. In a split-mouth design, one group of molars received EC40 at baseline, 6, 12, and 18 months, and another group at baseline, 3, 12, and 15 months. Control molars did not receive EC40. Adherence to the treatment protocol was good. The dropout rate was 17%. Blinded examiners performed dental examinations.The caries-inhibiting effects of the two EC40 application schemes were comparable. The prevented fraction of caries was 25% (95%CI, 1%, 49%, p = 0.04) after 2 years and 9% (95%CI, −11%, 29%, p = 0.20) one year after termination of the trial, suggesting a short-term benefit from the use of EC40. The efficiency of EC40 is questionable in low-caries-incidence child populations.

103 Background: To date, large populations of men from European ancestry have been prospectively evaluated on Active Surveillance (AS), a strategy reserved for low risk prostate cancer (PCa). African Americans (AA) deemed to be candidates for AS have yet to be fully characterized. We sought to determine the similarities and differences of our AS cohort stratified by race. Methods: We identified 308 men from our multi-institutional, prospective AS database were analyzed. Inclusion criteria was PSA < 20ng/mL, Gleason score ≤ 7, and clinical stage ≤ T2a. Men who sought treatment for their PCa or refused subsequent imaging and biopsy were excluded. Univariate analysis was done to analyze racial differences in demographic, clinical and pathologic variables. Results: We identified 308 men, 131 (43%) AA and 177 nonAA (57%). The groups were not significantly different with respect to age; 65 years, BMI 28.4, family history of PCa (22%), prior negative biopsy (21%) and clinical staging (87% T1c). Median follow-up is 25 months (IQR 12-44). Significant differences between the AA and nonAA cohorts did exist at baseline with respect to overall health, suggesting AA having worse overall health. More AA had diabetes (29 vs 14%; p = .03), were smokers (55 vs 29%; p < .01), cardiovascular disease (21 vs 9%) and erectile dysfunction (43 vs 18%; p < .01). Social characteristics also differed within the groups, with AA less likely to be married (47 vs 51%; p = .01). Despite a lack of difference with respect to biopsy Gleason score, AA had higher PSA (5.7 vs 5.0 ng/mL; p = 0.02), lower testosterone levels (250 vs 334 ng/dL; p = 0.05), greater PSA density (0.15 vs 0.12; p < 0.01), and greater linear length of cancer per biopsy core (16 vs 13mm; p < 0.01) at time of diagnosis and initiation of AS. Conclusions: Within our AS cohort, AA have worse overall health and more aggressive PCa features despite meeting inclusion criteria and selecting AS. Further prospective study is needed to determine how these competing factors may impact long term outcomes.

The Relationship

Background: Paired-box gene 9 (PAX9) mutation is potentially associated with impaction in some patient populations. Here, we analyzed the relationship between PAX9 polymorphism and the occurrence of maxillary canine impaction. Methods: Patients with and without maxillary canine impaction were selected based on specific inclusion criteria, and samples of genomic DNA were obtained from a buccal mucosa swab. DNA was amplified by polymerase chain reaction and sequenced for further bioinformatics analysis to identify single nucleotide polymorphism (SNP) genotypes. Genotype and allele counting was performed in both case and control groups prior to conducting statistical analysis. Results: Four SNPs were identified in patients with maxillary canine impaction, with relative confidence determined based on chromatogram-peak assessment. All SNPs were located in exon 3 of PAX9 and in the region sequenced by the primer pair −197Fex3 and +28Rex3. Three of the SNPs (rs375436662, rs12881240, and rs4904210) were reported previously and are annotated in NCBI (dbSNP version 150), whereas another SNP mapped to chromosome 14 has not been reported. Patients with a CC genotype at SNP 3 [odds ratio (OR): 2.61 vs. TT; 1.28 vs. CT] and a CC genotype at SNP 4 [OR: 0.71 vs. GG; 0.79 vs. CG] were more likely to have maxillary canine impaction. Conclusions: These results demonstrated that the presence of SNPs 3 and 4 is associated with increased likelihood of suffering from maxillary canine impaction.

<p><strong>Background: </strong>Acute puerperal metritis (APM) is a potentially life threatening, painful disease and is often treated with third-generation cephalosporins (Machado et al., 2014; Stojkov et al., 2015). An increasing antibiotic resistance is well documented and associated with decreasing clinical efficacy, animal welfare and economic consequences (Thomson et al., 2004). Hence, there is the need to evaluate alternative therapies to antibiotics.</p><p><strong>Objective:</strong> The objective of this study was to assess the efficacy of ketoprofen for the treatment of APM compared with ceftiofur hydrochloride.</p><p><strong>Materials and Methods:</strong> A total of 610 dairy cows from 6 farms in Germany were enrolled. Inclusion criteria was a rectal temperature (RT) ≥ 39.5 °C and a reddish-brown fetid vaginal discharge within the first 10 DIM. Cows meeting the inclusion criteria were randomly allocated to treatment with ketoprofen (3 mg/kg of body weight, n = 300) or treatment with ceftiofur (1 mg/kg of body weight, n = 310), both administered on 3 consecutive days. Rectal temperature was recorded daily for a period of 7 days after enrollment. Cows that showed RT ≥ 39.5 °C on day 4 to 7 after inclusion received an extended treatment (extT) with ceftiofur for 3 (ketoprofen group) or 2 (ceftiofur group) more days. Between 21 and 40 DIM cows were examined with the metricheck device and vaginal discharge was categorized on a 5-point scale according to the presence of pus.</p><p><strong>Results:</strong> A total of 52 cows (35 from ketoprofen group, 17 from ceftiofur group) were excluded from analysis due to missing protocol compliance (n = 37) or concurrent disease (n = 15). Cows initially treated with ketoprofen had higher odds of extT than cows treated with ceftiofur (61% vs 31%, OR 3.47, P &lt; 0.01, n = 558). Occurrence of purulent vaginal discharge (PVD) was similar for both treatment groups. However, cows with extT had 2.12 (P &lt; 0.01, n = 438) times the odds of PVD than cows without extended treatment. Treatment group did not affect milk yield, first artificial insemination pregnancy risk, time to first AI and time to pregnancy.</p><p><strong>Conclusions:</strong> The results indicate that although cows initially treated with ketoprofen were more likely to receive extT, fewer doses of ceftiofur (1.83) were required compared with cows initially treated with ceftiofur (3.63). Consequently, there is considerable potential of reducing antimicrobial treatment by implementing a treatment protocol starting with ketoprofen.</p><br /> <img src="https://www.veterinaryevidence.org/rcvskmod/icons/oa-icon.jpg" alt="Open Access" />

Understanding the problem of upper arches rehabilitation with implants in relation to the complain of lack of lip support, this study was designed to assess the potential of hyaluronic acid (HA) to increase lips volume and to fill the nasogenian groove in this group of patients. One hundred patients with rehabilitated maxilla with implant-supported hybrid fixed total prosthesis were selected. Of these, 86 attended the initial consultation and eight individuals were included in the study. The sample inclusion criteria were use of implant-supported fixed prosthesis in the maxilla with complaint of thin lips and deepening of the nasogenian groove and patients who agreed to participate of the study. Linear and angular measurements were drawn on initial an after procedure teleradiographies in order to assess lip protrusion before and after hyaluronic acid filling. Also standardized photographs were taken before and after the procedures, which were assessed by dentists and lay people. The participants of the study answered a questionnaire in order to assess the degree of satisfaction with the procedure. Hyaluronic acid filling presented significant differences (t1-t2) for upper and lower lip protrusion p= 0.001 and p=0.02, respectively. For the upper lip, the mean protrusion was 0.76mm + 1.88 (t1) before the filling with hyaluronic acid procedure and after filling the mean protrusion was 3.45mm + 1.58 (t2). Independent evaluators and practitioners assessed the facial profiles after the filling with HA, mostly as medium and significant better alterations. It can be concluded that lip and nasogenian sulcus filling in individuals rehabilitated with implant-supported total fixed implants increased self-esteem and provided close to normal lip protrusion.
