ABSTRACT Objective:  To assess camouflage effects by concealment of postorthodontic white-spot lesions (WSLs) to sound adjacent enamel (SAE) achieved over 12 months with resin infiltration (Icon, DMG, Hamburg, Germany). Methods:   Twenty subjects (trial teeth nteeth = 111) who had received resin infiltration treatment of noncavitated postorthodontic WSLs were contacted for a 1-year follow-up assessment of CIE-L*a*b* colors (T12). Color and lightness (CIE-L*a*b*) data for WSLs and SAE were compared to baseline data assessed before infiltration (T0) and those assessed after 6 months (T6), using a spectrophotometer. The target parameter was the difference between the summarized color and lightness values (ΔEWSL/SAE). Intergroup (WSL, SAE) and intertime comparisons (T0 vs T6, T12) were performed using paired t-tests at a significance level of α = 5%. Results:  Nine subjects (trial teeth nteeth = 49; male/female ratio 5/4; age range 13–19 years) were available at T12. After the highly significant reduction of ΔEWSL/SAE discrepancies between T0 and T6, analysis of 12-month records revealed color and lightness discrepancy of WSL vs SAE that was significantly decreased compared with baseline, indicating an assimilation of WSL color to SAE appearance after infiltration, while an additional reduction of discrepancies between T6 and T12 was not significant. Conclusion:  As color and lightness characteristics of the Icon infiltrant as well as the esthetic camouflage effects achieved by WSL infiltration were not altered significantly or clinically relevant after 12 months, the method of resin infiltration can be recommended for an enduring esthetic improvement of postorthodontic WSL.

ABSTRACT Objectives: To reassess the long-term camouflage effects of resin infiltration (Icon, DMG, Hamburg, Germany) of white spot lesions (WSL) and sound adjacent enamel (SAE) achieved in a previous trial. The null hypothesis was tested that there were no significantly different CIE-L*a*b*-ΔE-values between WSL and SAE areas of assessment after at least 24 months (T24) compared to those at baseline (T0). Materials and Methods: Of twenty subjects who received previous resin infiltration treatment of nteeth = 111 nonrestored, noncavitated postorthodontic WSL after multibracket treatment during a randomized controlled trial and were contacted 20 months after baseline, eight subjects (trial teeth nteeth = 40; m/f ratio 1/7; age range (mean; SD) 12–17 [15.25; 2.12] years); response rate: 40%) were available for follow-up after at least 24 months (T24). CIE-L*a*b* differences between summarized color and lightness values (ΔEWSL/SAE) of WSL and SAE were assessed using a spectrophotometer and compared to baseline data assessed prior to infiltration (T0), and those after 6 (T6), and 12 (T12) months using paired t tests at a significance level of α = 5%. Results: T24 assessments were performed after a mean 33.86 (SD: 8.64; Min: 24; Max: 45) months following T0. Mean (SD) ΔEWSL/SAE units of available teeth were 8.76 (5.33) at baseline; 5.5 (2.75) at T6; 5.2 (2.41) at T12; and 5.57 (2.6) at T24. Comparisons of T6, T12, and T24 with T0 yielded highly significant differences, whereas T6–T24 and T12–T24 differences were found to be not significant. Conclusions: Assimilation of infiltrated WSL to the color of adjacent enamel by resin infiltration is considered to be suitable for the long-term improvement in the esthetic appearance of postorthodontic WSL.

The Stability

The aim of this study is to evaluate the color changes and the stability at a 1-year follow-up of white spot lesions (WSLs) treated with an infiltrating technique by using etching and TEGDMA resin. The color of 22 white spot lesions and the sound adjacent enamel (SAE) were assessed with a spectrophotometer at T0 (baseline), T1 (after treatment), and T2 (1 year after). The color change ΔE (WSLs-SAE) at T0 vs. T1 were compared to evaluate the camouflage effect efficiency, and at T1 vs. T2 to assess the stability of outcomes. To evaluate the effect on the treatment outcome of gender, the presence or not of previous orthodontic treatment, WSLs onset more/less than 10 years, the age of the patient, and the ΔE WSL (T0 vs. T1) was analyzed. The difference between ΔE (WSLs-SAE) at T0 and T1 resulted in statistical significance (p < 0.01). No statistical difference was found between ΔE (WSLs-SAE) at T1 vs. T2. The variables considered showed no statistical differences in treatment outcomes. The results of our investigation show that the technique used is immediately effective and the camouflage effect keeps up and steady one year after treatment. Such results do not appear to be influenced by analyzed clinical variables.

Objective: to compare the clinical performance of newly introduced resin modified glass ionomer varnish (Clinpro™ XT) versus resin infiltration in treatment of post-orthodontic white spot lesions. Material and Methods: Six participants (70 teeth) were enrolled with post-orthodontic white spot lesions. Randomization was performed according to patient selection for the sealed envelope containing which half will receive the control (resin infiltration (ICON, DMG) and the other will receive the intervention (resin modified glass-ionomer cement varnish (Clinpro™ XT, 3M)). Follow up was done after 1 day, 1 week, 1 month, and 3 months, 6 months and 12 months. The color was assessed by spectrophotometer while the degree of demineralization was measured by Diagnodent pen 2910. Patient satisfaction was assessed using (VAS) Visual analogue scale. Results: Regarding color change, significant improvement in lightness for ICON group, while Clinpro™ XT group, the change was insignificant. The demineralization data revealed significant decrease in demineralization with resin infiltration after immediate application. Clinpro™ XT showed also significant decrease after immediate assessment and significant increase in demineralization in 6 and 12 months. Conclusion: Resin infiltration can be considered more as an alternative treatment rather than fluoride varnish. Clinpro™ XTis considered as a preventive protocol, provided that renewal application is needed after 3 months.

AbstractThe difference in refractive index between the healthy enamel and the demineralized area generates a lesion with a milky white opaque appearance, clearly distinguishable from the surrounding healthy enamel. The aim of this systematic review is to evaluate if the infiltration technique is the most efficient treatment to resolve a white spot lesion when compared with remineralization and microabrasion techniques. The Population/Intervention/Comparison/Outcome question investigated: “in enamel WS lesion, the infiltration treatment compared to remineralization or microabrasion treatments is more or less effective in the camouflage effect?” The research was performed on electronic databases, including Ovid MEDLINE, PubMed, and web of science. The search was conducted up to April 1, 2020. The scientific search engines produced 324 results. Only 14 were screened after screening. Based on the articles analyzed in this systematic review, the resin infiltration technique seems to be the most effective and predictable treatment for the aesthetic resolution of WSLs.

Background: Spondyloarthropathies include a wide spectrum of disease. The study was conducted with the aim of observing the efficacy of SSZ and MTX in different subclasses of spondyloarthropathies and to compare the treatment response of the two drugs. Methods: This study was conducted in the Department of Medicine and Rheurnatology clinic of Bangabandhu Sheikh Mujib Medical University (BSMMU) between January 1999 and July 2001.A total number of one hundred twenty five patients was included in the study. Patients with active disease more than three months, regularly taking NSAIDs and not on DMARD in the last three months were included in the study. Monthly follow up of the patients was done for 6 months. Result: One hundred twenty five patients were included in this study. Male female ratio was 11.5:1. Mean age of patients was 24.17±7.15 years. The mean disease duration was 47.8±32.8 months. The present study categorized the patients into responder and non responder. Among the 78 patients in AS subclass, after completion of 6 month trial 55.6% patients in SSZ group and 39.4% patients in MTX group were categorized responder. The difference of response between drug groups was not significant (p=0.158). In the JCA subclass 81.82% in SSZ and 50% in MTX group were responder. The numbers of patient in Reiter's/Reactive Arthritis in our study were too small to make a definite comment. Conclusion: It can be concluded from this study that both the SSZ and MTX are effective DMARDs for spondyloarthropathies. Statistical analysis did not prove superiority of one drug over another, though the response rates were numerically higher in SSZ group. TAJ 2011; 24(1): 43-47

Objectives: The objectives of the study were to assess the white spot lesions around orthodontic bracket macroscopically using two different bonding agents – one with amorphous calcium phosphate (ACP) (Aegis Ortho) and one without ACP (Transbond XT). Materials and Methods: The study comprises 10 patients from 14 to 23 years of age. Patients were divided into control and study groups. Forty premolar teeth were then observed (20 teeth in each group). Bonding procedure was done and brackets were positioned on all four 1st pre-molars teeth and pre-treatment photographs were taken. The experimental material used was Aegis Ortho composite (study group) and Transbond XT (control group). Debonding procedure (by Wing deformation technique) was performed after 16 weeks which led to adhesive fracture at composite resin adhesive bracket interface leaving essentially all adhesive on the enamel. Then, follow-up photographs were taken to evaluate each. Results: Aegis Ortho containing ACP used for bonding purpose, provided lesser enamel demineralization than Transbond XT. Conclusion: Aegis Ortho for orthodontic bonding is significantly more beneficial and reliable, however, further investigations are also required to understand its clinical performance better.

Purpose. To retrospectively evaluate the effectiveness of intra-articular application of Sluijter-Teixera Poisson pulsed radiofrequency (STP PRF) in knee osteoarthritis symptomatic patients with chronic pain refractory to conservative therapies. Materials and Methods. Institutional database research of two centers identified 39 cases of knee osteoarthritis patients treated with intra-articular STP PRF. Pain prior and one-week and one-, three-, six-, and twelve-month post-STP PRF was compared by means of a numeric visual scale (NVS) questionnaire. Cardiovascular and Interventional Radiological Society of Europe (CIRSE) classification system was used for complications reporting. Mean patient age was 71.59 ± 11.99 years, mean body mass index was 30.23 ± 4.69, and male/female ratio was 9/30. Results. Mean baseline pain score was 8.31 ± 1.70 NVS units. This was reduced to a mean value of 0.90 ± 1.50 NVS units one-week post-RF, 1.08 ± 1.53 at one month, 1.54 ± 1.88 at three months, 2.33 ± 2.17 at six months, and 3.23 ± 2.23 at 12 months of follow-up p < 0.01 . Pain decrease of more than 4 NVS units was noticed in 35/39 knees (89.7%) at first week, 36/39 knees (92.3%) at first month, 35/39 knees (89.7%) at three months, 32/39 knees (82.1%) at six months, and 25/39 knees (64.1%) at one year. There was no recurrence during the follow-up. No complication was observed. Conclusions. Percutaneous, intra-articular application of STP PRF is an effective and safe technique for chronic pain reduction in patients with knee osteoarthritis. Results seem to be reproducible and long lasting with significant patient satisfaction at 12-month follow-up.
