Background: Interproximal enamel reduction is a valuable procedure in orthodontics used in several conditions, however, not knowing the average value of proximal enamel thickness might lead to excess enamel removal and consequently to adverse effects. Objective: The objective of this systematic review is to expose the average proximal enamel thicknesses found in the literature, and the differences that might be found between different ethnicities and age groups. Search Methods: 5 electronic databases were used to perform the search. Representative keywords comprised of “enamel”, “thickness”, “orthodontics” “proximal thickness” and “quantification”; different combination of these keywords with truncation, and medical subject headings (MESH) were used. Selection Criteria: In vitro and in vivo studies, where the quantification of the proximal enamel thickness of the mesial and distal sides were evaluated independently. Data Collection and Analysis: The PICO model was used to evaluate a...

The aim of this in vitro study was to evaluate the stripping achieved on different teeth (incisors, canines, and premolars) by two grades of abrasive strips used for the first and tenth time. Our second aim was to test the efficacy of these strips by calculating the time necessary to perform interproximal reductions of 0.10, 0.20, and 0.30 mm. Four models were constructed using extracted teeth affixed in wax. The upper and lower arches were set on plaster bases and fixed in wax, carefully creating contact points. All model mouths were treated with artificial saliva (Oral Balance®) in order to simulate the biological conditions in the oral cavity. We then tested specific air-rotor strips of different grades and degrees of wear (15-µm-grain and 25-µm-grain Orthofile® strips). Afterwards the teeth from all samples were cut lengthwise in half, and each mesial and distal portion was gold-plated and observed under SEM at incremental magnification (30, 60, and 100 µm). The 25-µm-grain stri...
Interproximal reduction of teeth: Differences in perspective between orthodontists and dentists
The Angle Orthodontist, 2014
Objective: To determine if interproximal reduction of teeth (IPR) is perceived differently by orthodontists and general dentists. Materials and Methods: A Web-based survey containing statements about IPR was developed and randomly distributed to orthodontists and general dentists. Results: The majority of orthodontists and general dentists strongly agreed that IPR is a minimally invasive procedure that poses little risk for the development of interproximal decay. However, general dentists were more likely to perform post-IPR polishing and to apply topical fluoride than are orthodontists (P < .0001). A greater percentage of orthodontists strongly believed that the esthetic and occlusal benefits of IPR outweigh the potential risk of tooth decay when IPR was performed (P < .0001). A greater percentage of general dentists were hesitant to perform IPR, despite research supporting that IPR has little negative effect on the health of teeth. Conclusions: The results of this study ...
Qualitative Evaluation of Changes In Vivo After Interproximal Enamel Reduction
oral health and dental management, 2011
To use a laser fluorescence device to assess the qualitative changes in interproximal enamel after enamel reduction (interproximal stripping). Methods: Fifty-three patients (32 females and 21 males) with an average age of 15.6 years took part in the investigation. Five hundred and thirty-five tooth surfaces of upper and lower anterior teeth were reassessed at three days, ten days, and one month after enamel reduction using a laser fluorescence method (DIAGNOdent pen). Remineralisation was promoted by the application of fluoride gel and control of oral hygiene. Results: The results showed that there is no risk for developing caries after stripping in cases where intact enamel surfaces registered values of between 0 and 3 when measured with the laser fluorescence method used in this study. Enamel reduction appeared to be appropriate even for surfaces with initial demineralisation of the outer enamel, with values between 4 and 6, because after fluoride application the enamel status ret...
Interproximal Reduction Facilitating Orthodontic Teeth Extraction
Cureus Part of Springer Nature Group, 2023
Extractions are routinely performed in orthodontics to gain space for teeth alignment. Crowded, malaligned, and overlapped teeth make it difficult for the dental surgeon to engage the beaks of the extraction forceps on the concerned tooth for extraction. An improper grip often leads to complications of instrument slippage, crown fracture, and more commonly, luxation of adjacent teeth. This article aims to help with atraumatic orthodontic extractions and reduce such complications. This case report examines an interproximal reduction technique using standard grit, taper, flat-end diamond bur (Mani TF-20, ISO 171/014, Mani, Inc., Tochigi, Japan) for the tooth to be extracted to create enough space for proper placement of the forceps and to prevent injury to adjacent structures. It can be useful for orthodontic extractions or other cases of tooth extractions with inadequate access.

Background The aim of the present investigation was to evaluate enamel reduction efficiency, abrasive property decay, and enamel effects between oscillating mechanical and manual systems for interproximal enamel reduction (IPR). Methods Three oscillating strips and three manual strips were tested on twelve freshly extracted premolars blocked in an acrylic cylinder pot by means of a material testing machine. Each strip underwent one test of 8 cycles (30 s each). Both abrasive tracks and teeth surfaces were qualitative evaluated before and after IPR by means of SEM analysis. Efficiency and abrasive property decay of both IPR systems were investigated by the amount of enamel reduction within the eight-cycle testing. Independent t-test was used to evaluate differences in variables between the two systems. Results Mechanical IPR system showed higher efficiency in terms of enamel reduction (p < 0.005) when compared with manual IPR system (0.16 mm and 0.09 mm, respectively). Quantity of...
Interproximal reduction in orthodontics: why, where, how much to remove?
Australasian Orthodontic Journal, 2021
Interproximal reduction (IPR) is the deliberate removal of part of the dental enamel from the interproximal contact areas, which decreases the mesiodistal width of a tooth. This enamel may be removed for various reasons, but most commonly to create space during orthodontic treatment or to correct tooth-size discrepancies. Several authors have also encouraged its use as a method by which post-orthodontic stability might be enhanced, particularly in the lower anterior region. With the increased use of removable aligners for orthodontic treatment in which non-extraction therapy is often advocated, the use of IPR becomes a valuable tool to relieve crowding without over-expanding the dental arches. It is possible that inaccurate IPR could result in the over-reduction of enamel, the creation of ledges and notches in the proximal surfaces, increased tooth sensitivity or damage to the surrounding soft tissues. However, carefully conducted IPR performed within the recommended guidelines may ...
Veneer or Interproximal Enamel Reduction?
The Journal of Contemporary Dental Practice
Background: Clinicians often ask, "Veneer or no to veneer?" Clinicians usually think of porcelain veneers for cases in which patients are dissatisfied with their teeth shape. Interproximal reduction can change teeth's shape and appearance within the enamel to improve gingival contour, eliminate black gingival triangles, and correct the Curve of Spee. Aim: Our aim is to present to clinicians the option of reshaping and interproximal reduction (IPR) as a valid alternative to porcelain veneers. Case report: A male patient with round bulbous-shaped anterior maxillary teeth sought a better masculine smile. Interproximal reduction with thin bur size was performed to reshape the anterior teeth in order to achieve a proportional teeth width to height and give a more rectangular rather than square shape. Finally, the orthodontist closed the multiple diastemas using round wires in order to reduce anterior teeth proclination. The patient received bleaching treatment and minor composite fillings. Conclusion: Not every cosmetic case should be treated with veneers and crowns. Conservative minimal intervention, such as IPR was more than sufficient in treating such cases. It is the right of the patients to be informed and educated about all possible treatment options. Clinical significance: Minor reshaping and IPR preserving teeth structures can be helpful in achieving esthetic results and patients' confidence.

Background The aim of the study was to compare the amount of interproximal enamel reduction (IPR) provided on ClinCheck software with the amount of IPR carried out by the orthodontist during treatment with clear aligners. Methods 30 subjects (14 males, 16 females; mean age of 24.53 ± 13.41 years) randomly recruited from the Invisalign account of the Department of Orthodontics at the University of Rome “Tor Vergata” from November 2018 to October 2019, were collected according to the following inclusion criteria: mild to moderate dento-alveolar discrepancy (1.5–6.5 mm); Class I canine and molar relationship; full permanent dentition (excluding third molars); both arches treated only using Comprehensive Package by Invisalign system; treatment plan including IPR. Pre- (T0) and post-treatment (T1) digital models (.stl files), created from an iTero scan, were collected from all selected patients. The OrthoCAD digital software was used to measure tooth mesiodistal width in upper and lower ...

After orthodontic treatment, brackets are debonded and residual adhesive is removed, causing iatrogenic enamel damage. The aim of this study was to review the methods of orthodontic adhesive removal, find clear evidence, and provide a rationale for this procedure. A literature search was performed in PubMed, Dentistry and Oral Sciences, Scopus, Cochrane, Google, and Google Scholar using keywords: orthodontic adhesive removal, orthodontic debonding, orthodontic clean-up. Studies concerning human enamel roughness or loss from debonding and adhesive removal were considered. Forty-four full-text articles were analyzed and 3 were rejected after detailed reading; finally 41 papers were included. Fifteen qualitative studies, 13 studies based on indices of enamel surface, and 13 quantitative studies were found. No meta-analysis could be performed due to a lack of homogenous quantitative evidence. The most popular tools were tungsten carbide burs, which were faster and more effective than So...
