- Interdental space is one of the most common site for the dental pathology may it be caries or any periodontal lesions.
- Any imperfections in the interdental area (tooth or periodontium related) may lead to the accumulation and retention of biofilm causing dental lesions.
- Hence it is necessary to have the basic understanding of anatomy and histopathologic make-up of this area labio-lingually, mesio-distally and occluso-cervically for periodontal & restorative considerations.
Interdental area is composed of
1. Proximal contact area
2. Interproximal spaces (formed by proximal surface in contact)
3. Embrasures (spillways)
4. Interdental gingiva (Buccal and lingual interproximal papilla plus Interpapillary Saddle or COL)
