Updates to Article Attributes

Title was changed:
Odontogenic tumours (classification) -2005 WHO 1992histological classification of odontogenic tumours
Body was changed:

The 2005 WHO histological classification scheme forof odontogenic tumours (1992) lays lays out a classification system for neoplasms and other tumours related to the odontogenic apparatus. At the time of writing (2016) it is still the most widely used classification system.
