“…Undoubtedly, the orthodontic appliances increase the caries risk ( 28 ). Therefore, it is important to emphasize that of all tested adhesives, only in Fuji Ortho LC, the elemental composition obtained by surface SEM/EDX analyses, as well as the semiquantitative SEM/EDX line-scan analysis of randomly selected points in the surface of the enamel, showed the presence of fluorides, which is known to have anticariogenic properties ( 29 ).…”

Objectives To compare three different orthodontic adhesives (Transbond XT Light Cure Adhesive, Heliosit Orthodontic, Fuji Ortho LC) bonded to two types of orthodontic brackets: ceramic brackets (Fascination Roth 0.22) and metallic brackets (Topic Roth 0.22, Dentaurum). Materials and methods The study was performed on 18 human teeth (6 for each adhesive). The prepared teeth were divided into three groups according to the examination time. Subsequently, they were observed after 1, 2 and 3 weeks following bonding. After the experimental procedure, the teeth samples were cut in half along the longitudinal axis in the vestibulo-oral direction, fixed with conductive carbon cement, placed in a high-vacuum evaporator and then coated with carbon. One half of each sample was observed under a Field-emission gun scanning electron microscope (FEG-SEM Hitachi SU 8030, Japan), while on the second half of the samples qualitative (X-ray line-scans) and semi-quantitative point X-ray energy dispersive analyses (EDX) were performed with Thermo Noran (USA) NSS System 7, equipped with Ultra Dry detector (30 mm 2 window). Results Transbond XT had an ideal bond with the enamel and the bracket base, with rare presence of microgaps and cracks in the enamel. Heliosit Orthodontic demonstrated a better bond relationship with the bracket base than the enamel, whereas in the latter the presence of microgaps in the bond was observed. The microphotographs of Fuji Ortho LC demonstrated many cracks inside the adhesive, and some of them continued to move forward into the enamel surface. Therefore, an impression of a very solid bond relationship with the enamel exists, with cracks being present in the enamel surface and never at the enamel-adhesive interface. Microgaps also appeared at the bracket-adhesive interface. Conclusion Transbond XT is a highly filled composite resin and is an ideal orthodontic adhesive in each aspect examined, with an ideal enamel-adhesive and bracket-adhesive interface. Heliosit Orthodontic provides better bracket-adhesive interface compared to the enamel. Fuji Ortho LC as a solid resin-modified GIC provides a better enamel-adhesive interface, compared to the bracket base.

“…In a clinical study published in 2019 by Jurela et al, 83 patients with a medium age of 15.14 ± 1.66 (52 men and 31 women) receiving FOT were examined [ 22 ]. The study’s goal was to estimate the patients’ clinical and salivary changes and see whether there were statistically meaningful variations concerning the type of braces they wore (conventional vs. self-ligating brackets) [ 21 , 38 ].…”

Early-stage dental demineralization, called white spots (WS), get their name from the characteristic colour that enamel takes on due to the acid attack of salivary cariogenic bacteria. They are often associated with fixed orthodontic therapy (FOT) and, if left untreated, evolve into caries with repercussions on oral health and dental aesthetics. This review aims to identify the most effective prophylaxis strategies to prevent WS during FOT. The search for the reviewed studies was conducted on the Pubmed, Scopus, and Web of Science databases, selecting English-only articles published in the 5 years from January 2018 to January 2023. The keywords used were “WS” and “fixed orthodontic*”, using “AND” as the Boolean operator. A total of 16 studies were included for qualitative analysis. Prevention begins with maintaining proper oral hygiene; fluoride in toothpaste, mouthwashes, gels, varnishes, and sealants can be added to prophylaxis and used regularly. Using a laser in combination with fluoride helps prevent the occurrence of WS and assists in the repair processes of initial lesions. Further studies are needed to establish international guidelines for preventing WS in orthodontically treated patients.

“…2,3 Plaque accumulation was found to be greater in patients with ceramic brackets followed by metal and self-ligating brackets. [4][5][6] Increased plaque accumulation necessitates oral prophylaxis at regular intervals to maintain proper oral hygiene. But ultrasonic instrumentation has also been found to diminish the bonding strength of orthodontic brackets.…”

Aim: Accumulation of plaque during orthodontic treatment makes oral prophylaxis a regular necessity. The use of esthetic brackets has gained popularity, it becomes necessary to assess the consequences of ultrasonic instrumentation during oral prophylaxis on ceramic bracket’s shear bond strength (SBS). Materials and Methods: Fifty-four premolar teeth which were extracted due to therapeutic reasons were divided into six groups with each group containing nine teeth each. Ceramic brackets were bonded onto the labial surfaces using two different adhesive systems (Ormco Enlight and Transbond) and were subjected to ultrasonic scaling at different scaler tip angulations. The samples were then rendered a debonding force in a Universal testing machine and the bond strengths were assessed. Results: In terms of angulation of ultrasonic instrumentation, among the groups bonded with the Ormco Enlight, the 45° angulation group had statistically significant higher bond strength values compared to the 0° angulation group. Among the transbond groups, there was no statistically significant difference in the bond strengths even though the 45° angulation group had slightly higher bond strength value than the 0° angulation group. Conclusion: Supragingival scaling around the bracket base at 0° around the ceramic brackets for 1 min resulted in the reduction of SBS. Therefore, the clinicians should be cautious during plaque removal, avoid performing extended ultrasonic instrumentation at the bracket base, especially at 0° angulation.
