ANATOMY

Detailed explanation-1: -Bone between the teeth is called interdental septum and is composed entirely of cribriform plate. interdental and interradicular septa contain the perforating canals of Zuckerkandl and Hirschfeld (nutrient canals) which house the interdental and interradicular arteries, veins, lymph vessels and nerves.

Detailed explanation-2: -Furcation is defined by the glossary of periodontal terms as “the anatomic area of the multirooted tooth where the roots diverge” and “furcation invasion refers to the pathologic resorption of bone within a furcation” [1, 2].

Detailed explanation-3: -The alveolar septum is also called the interalveolar septum or the interradicular septum, and is one of the very thin plates of bone that separates the alveoli or tooth sockets in the teeth from one another in both the maxillary alveolar ridge and the lower alveolar ridge.

Detailed explanation-4: -The alveolar bone located between the two neighboring teeth is the interdental septum or the interdental bone.
