ABSTRACT Introduction: Debris buildup on the bracket-wire interface can influence friction. Cleansing brackets with air-powder polishing can affect this process. Objective: The aim of this study was to evaluate the frictional force and amount of debris remaining on orthodontic brackets subjected to prophylaxis with air-powder polishing. Methods: Frictional force and debris buildup on the surface of 28 premolar brackets were evaluated after orthodontic treatment. In one hemiarch, each bracket was subjected to air-powder polishing (n = 14) for five seconds, while the contralateral hemiarch (n = 14) served as control. Mechanical friction tests were performed and images of the polished bracket surfaces and control surfaces were examined. Wilcoxon test was applied for comparative analysis between hemiarches at p < 0.05. Results: Brackets that had been cleaned with air-powder polishing showed lower friction (median = 1.27 N) when compared to the control surfaces (median = 4.52 N) (p < 0.01). Image analysis showed that the control group exhibited greater debris buildup (median = 2.0) compared with the group that received prophylaxis with air-powder polishing (median = 0.5) (p < 0.05). Conclusion: Cleansing orthodontic brackets with air-powder polishing significantly reduces debris buildup on the bracket surface while decreasing friction levels observed during sliding mechanics.

Despite the continuous development of materials and techniques of adhesive bonding, the basic procedure remains relatively constant. The technique is based on three components: etching substance, adhesive system, and composite material. The use of etchants during bonding orthodontic brackets carries the risk of damage to the enamel. Therefore, the article examines the effect of the manner of enamel etching on its thickness before and after orthodontic treatment. The study was carried out in vitro on a group of 80 teeth. It was divided into two subgroups of 40 teeth each. The procedure of enamel etching was performed under laboratory conditions. In the first subgroup, the classic method of enamel etching and the fifth-generation bonding system were used. In the second subgroup, the seventh-generation (self-etching) bonding system was used. In both groups, metal orthodontic brackets were fixed and the enamel was cleaned with a cutter fixed on the micromotor after their removal. Before and after the treatment, two-dimensional optical coherence tomography scans were performed. The enamel thickness was assessed on the two-dimensional scans. The average enamel thickness in both subgroups was not statistically significant.

Surface Changes

Despite careful patient selection, decalcification still remains a problem during fixed orthodontic treatment. The advantages of a method of delivering fluoride to the area of the tooth most at risk, which does not rely on patient compliance, makes a fluoride releasing bonding adhesive desirable. The aims of this study were to investigate the potential of a fluoride releasing bonding material for preventing decalcification and to monitor its efficacy at retaining orthodontic brackets. In order to carry out the first part of the study it was necessary to devise a reproducible and sensitive method of recording the extent and severity of any decalcification. A photographic technique which fulfils these criteria is described.

Keberadaan kista dapat menghambat perawatan ortodontik konvensional yang diberikan pada pasien. Tujuan artikel ini adalah menyajikan laporan kasus perawatan ortodontik alternatif seorang pasien perempuan berusia 17 tahun dengan kondisi gigi atas berjejal berat dan kista jinak di antara gigi insisivus lateral dan kaninus kiri atas. Setelah menetapkan diagnosis ortodontik, perawatan pertama yang dilakukan adalah pengangkatan kista. Kista dikirim untuk biopsi dan didiagnosis sebagai kista jinak. Orang tua dan pasien memutuskan untuk mencabut gigi insisivus lateral atas setelah mengetahui bahwa gigi insisivus lateral kiri atas nekrosis. Setelah gigi dicabut, bracket ortodontik dipasang di gigi bawah pasien. Tiga bulan kemudian, bracket ortodontik dipasang di gigi atas pasien. Kondisi gigi atas yang berjejal terkoreksi dan kaninus atas menggantikan posisi insisivus lateral. Saat ini, perawatan aktif masih dilanjutkan dan terpasang bracket ortodontik dengan elastik kelas III pada pasien. Kesimpulan artikel ini adalah pendekatan perawatan ortodontik inkonvensional dapat menjadi pertimbangan ketika ditemukan hambatan seperti adanya kista. Pasien dan orang tua harus diberi informasi mengenai konsekuensi perawatan sebelum perawatan dimulai.Unconventional Orthodontic Treatment for Upper Teeth Crowding with Benign Cyst. The presence of a cyst can provide an obstacle to the conventional orthodontic treatment given to the patients. The purpose of this article is to describe a case report of a seventeen year-old girl with a severe crowding of maxilla and presence of benign cyst between lateral incisor teeth and upper left canine treated with an alternative orthodontic treatment plan. After orthodontic diagnosis, the first treatment to be conducted was the removal of the cyst. The cyst was sent for biopsy and diagnosed as non-malignant cyst. The patient and her parents decided to extract upper laterals incisor tooth after knowing that the upper left lateral incisor tooth was necrotic. After the extractions, orthodontic brackets were bonded on the mandible. Then three months later the maxilla was bonded. The upper crowding of teeth condition was resolved very promptly and the upper canines were used to replace the laterals incisor position. Currently, active treatment is still in progress, and the patient has full upper and lower orthodontic brackets with class III elastics. After the treatment so far, it can be concluded that unconventional orthodontic treatment is worth considering when an obstacle such as a cyst is present. Patients and parents must be informed about the consequences of the treatment before active treatment is started.

The objective of this study is to assess,in vitro, the shear bond strength of orthodontic brackets fixed with remineralizing adhesive systems submitted to thermomechanical cycling, simulating one year of orthodontic treatment. Sixty-four bovine incisor teeth were randomly divided into 4 experimental groups (n=16):XT: Transbond XT,QC: Quick Cure,OL: Ortholite Color, andSEP: Transbond Plus Self-Etching Primer. The samples were submitted to thermomechanical cycling simulating one year of orthodontic treatment. Shear bond strength tests were carried out using a universal testing machine with a load cell of 50 KgF at 0.5 mm/minute. The samples were examined with a stereomicroscope and a scanning electron microscope (SEM) in order to analyze enamel surface and Adhesive Remnant Index (ARI). Kruskal-Wallis and Mann-Whitney (with Bonferroni correction) tests showed a significant difference between the studied groups (p<0.05). Groups XT, QC, and SEP presented the highest values of adhesive resistance and no statistical differences were found between them. The highest frequency of failures between enamel and adhesive was observed in groups XT, QC, and OL. Quick Cure (QC) remineralizing adhesive system presented average adhesive resistance values similar to conventional (XT) and self-etching (SEP) adhesives, while remineralizing system (OL) provided the lowest values of adhesive resistance.

The purpose of this study was to investigate the combined effect of mechanical and chemical treatments on the shear bond strength (SBS) of metal orthodontic brackets on zirconia restoration. The zirconia specimens were randomly divided into 12 groups (n=10) according to three factors: AL (Al2O3) and CO (CoJet™) by sandblasting material; SIL (silane), ZPP (Zirconia Prime Plus), and SBU (Single Bond Universal) by primer; and N (not thermocycled) and T (thermocycled). The specimens were evaluated for shear bond strength, and the fractured surfaces were observed using a stereomicroscope. Scanning electron microscopy images were also obtained. CO-SBU combination had the highest bond strength after thermocycling (26.2 MPa). CO-SIL showed significantly higher SBS than AL-SIL (p<0.05). CO-ZPP resulted in lower bond strength than AL-ZPP before thermocycling, but the SBS increased after thermocycling (p>0.05). Modified Adhesive Remnant Index (ARI) scoring and SEM figures were consistent with the results of the surface treatments. In conclusion, CO-SBU, which combines the effect of increased surface area and chemical bonding with both 10-MDP and silane, showed the highest SBS. Sandblasting with either material improved the mechanical bonding by increasing the surface area, and all primers showed clinically acceptable increase of shear bond strength for orthodontic treatment.

ABSTRACT Introduction Esthetics is one of the common issues because of which patients consult dental orthodontic treatment. Two ways of tooth bleaching are available these days, which includes in-office bleach and home bleach. Various bleaching protocols are available these days for treating the tooth surfaces. Hence, we planned the present study for investigating the impact of various intracoronal bleaching protocols on shear bond strength of ceramic brackets bonded to tooth surface after bleaching. Materials and methods The present study included assessment of 100 extracted maxillary central incisors with the integrated buccal surface. A resin block was made and individual teeth were embedded in each block. Root canal therapy procedure was performed in all the teeth, after which 2 mm short of tooth apex up to the level of cementoenamel junction, removal of the root canal filling was done. All the samples were broadly divided into four study groups with 25 samples in each group. Bleaching procedure was carried in all the samples intracoronally followed by testing of shear bond strength using universal force testing machine. Following the modified adhesive remnant index (AI), assessment of remaining adhesive on the brackets was done. All the results were compiled and analyzed by Statistical Package for the Social Sciences (SPSS) software version 17.0. Results In the control group, mean shear bond strength was found to be 17.9 MPa. While comparing the carbamide peroxide (CP) group with sodium perborate study group, we observed a statistically significant difference. Nonsignificant results were obtained while comparing the shear bond strength in between sodium perborate group and hydrogen peroxide (HP) group. Conclusion Intracoronal bleaching does affect the shear bond strength of ceramic brackets. Sodium perborate bleaching influences shear bond strength more strongly than other bleaching agents such as CP and HP. Clinical significance In patients undergoing orthodontic treatment, HP is a preferred agent where bleaching has to be followed by orthodontic bonding to the tooth surface.

ABSTRACT Introduction: Debris buildup on brackets and arch surfaces is one of the main factors that can influence the intensity of friction between bracket and orthodontic wire. Objective: This study sought to evaluate the effect of air-powder polishing cleaning on debris levels of self-ligating ceramic brackets at the end of orthodontic treatment, compared to the behavior of conventional brackets. Methods: Debris levels were evaluated in metal conventional orthodontic brackets (n = 42) and ceramic self-ligating brackets (n = 42) on canines and premolars, arranged in pairs. There were brackets with and without air-powder polishing. At the end of orthodontic treatment, a hemiarch served as control and the contralateral hemiarch underwent prophylaxis with air-powder polishing. Debris buildup in bracket slots was assessed through images, and Wilcoxon test was used to analyze the results. Results: The median debris levels were statistically lower in the conventional metal brackets compared to self-ligating ones (p = 0.02), regarding brackets not submitted to air-powder polishing. Polishing significantly reduced debris buildup to zero in both systems, without differences between groups. Conclusions: Ceramic self-ligating brackets have a higher debris buildup in comparison to conventional metal brackets in vivo, but prophylaxis with sodium bicarbonate jet was effective in reducing debris levels in self-ligating and also in conventional brackets.

ABSTRACT Objectives To evaluate and compare the biofilm formation between labial and lingual orthodontic brackets. Materials and Methods Twenty patients with a mean age of 24 ± 8.8 who had received labial or lingual orthodontic treatment were enrolled in the study. Biofilm formation on 80 brackets was analyzed quantitatively with the Rutherford backscattering detection method. Five micrographs were obtained per bracket with views from the vestibule/lingual, mesial, distal, gingival, and occlusal aspects. Quantitative analysis was carried out with surface analysis software (ImageJ 1.48). Data were analyzed by Mann-Whitney U and Kruskal-Wallis tests (α = 0.05). Results Total biofilm formation was 41.56% (min 29.43% to max 48.76%) on lingual brackets and 26.52% (min 21.61% to max 32.71%) on labial brackets. Differences between the two groups were found to be significant. No difference was observed in intraoral location. The biofilm accumulation was mostly located on gingival, mesial, and distal surfaces for both groups. Conclusions The biofilm accumulation on lingual orthodontic therapy was found to be more than labial orthodontic therapy.
