Our previous report comparing the efficacy of various interdental cleaning means revealed the use of dental floss or Interdental-Brush (Denticator Co.) was more preferable than others such as rubber tip and wooden stimulator.
However, the limitation of the use of Interdental-Brush was noticed in cases where the narrow interdental space were present.
The present work was perfomed to investigate the inter-cervical distance of approximating tooth. Thirty-five human dry skulls with normal dentition and twenty periodontal patients comprised the material.
The mean interdental distance (measured from 666 inter-dental spaces) was found as 1.4mm for human dry skulls and the same value was obtained for the periodontal patients (measured from 243 interdental spaces).
The mean intercervical distance which allowed the passage of Interdental-Brush was found as 1.6mm, while the mean intercervical distance which did not allow the passage was found as 1.0mm.
