RESUMEN
Interproximal reduction, referring to the reduction of tooth structure in the proximal surfaces of anteriors or posteriors as required by the clinical scenario, has most often intrigued the orthodontist and the general dentist in particular in implementing it in contemporary orthodontics on a regular basis. The reduction of tooth structure as likelihood for the development of dental caries proximally, when the patient is undergoing orthodontic therapy, can in itself be a subject of debate between the conservative general dentists and the orthodontist. With recent treatment options for minimal space requirements in aligning teeth and others such as clear aligner therapy which involve the use of proximal stripping, this review aims to present the current concepts in interproximal reduction and its questionable role as an etiological factor in the development of caries.
