Effectiveness of the Touch-to-Teach Method for Interdental Brushing in Patients With Stage II Grade B Periodontitis.

Overview

In 2018, a collaboration between American Academy of Periodontology (AAP) and European Federation of Periodontology (EFP) yielded a new classification system for periodontal diseases and conditions. The new classification categorized periodontitis into stages from I to IV based on the severity of the disease. Besides the stages, cases were also categorized into A, B and C grades based on the probable progression of the disease. Likewise, cases with interproximal clinical attachment loss of 3-4 mm in the worst affected teeth are considered to be stage II periodontitis.\[3\] These patients usually do not have tooth loss, can be suffering from localized or generalized type and mostly show horizontal bone loss. There are three types of gingival embrasures. In type I embrasure, the gingival embrasure is filled by the interproximal papilla; whereas in type II and III embrasures interdental papilla loss is seen. Interdental brushing has a vital role in maintaining good oral hygiene and previously published reports have evidenced that successful interdental brushing eliminated interdental plaque below the gingival margin up to 2-2.5 mm. According to the old school of thought, dental floss was advised for type I embrasures, interdental brushes for type II embrasures and unitufted brushes for type III embrasures. Usage of dental floss has been identified to be cumbersome and especially challenging in posterior regions of the oral cavity. Additionally, a recent systematic review in the Cochrane database highlighted the effectiveness of interproximal brushes over dental floss.\[9\] Recently, the implementation of calibrated interdental brushes use with the availability of interdental brushes with varying sizes, added effectively in creating a healthy interdental papilla in a safe manner. Essentially, a patient-centered and personalized approach named "individually trained oral prophylaxis (iTOP)" has recently been suggested as a solution to remove dental plaque effectively.\[10\] This concept known as the "Touch-to-Teach" concept provides the patients with an effective method to educate the patients an effective and non-traumatic way of removing interdental plaque.\[10\] Although, the effectiveness of calibrated interdental brushes showed high efficacy in cases of gingivitis, currently, the effectiveness of these brushes in stage II periodontitis has not been comprehensively studied yet in literature.
