Palatal rugae patterns situated in the anterior third of palate have been studied for various purposes and reports have been published mainly in the fields of anthropology, comparative anatomy, genetics, forensic odontology, and dental specialties (specially prosthodontics and orthodontics).,,,, Study of rugae is called as rugoscopy and rugae have been classified by various scientists according to the position, length, shape, direction, and unification.,,
This letter calls for attention to propose a simple working Integrated Rugoscopy Chart (IRC) for analysis and recording rugae pattern, based on various earlier classifications of rugae [Figure 1]. IRC will be a useful resource as it has several advantages, among which are its ability to carry enormous volume of information and reproduce position, length, shape, direction and unification of rugae on dental casts unmistakably, and in detail on a cost-effective basis.
Explanation of IRC (following sections describes how to go about filling each section of IRC):
- Position: This tells the address/location of the rugae. The rugae are designated as left/right and to which quadrant they belong. Palatal rugae area is divided into quadrants, with the goal of attaining the coordinates/position of palatal rugae. For this, six horizontal lines [Figure 2] divide the cast into five zones [Figure 3]
- Length: Rugae are measured in a straight line between the origin and termination and are grouped into three categories: primary (5 mm or more), secondary (3–5 mm), and fragmentary (2–3 mm). Rugae < 2 mm are disregarded
- Shape: Based on appearance rugae can be curved/wavy/straight/circular [Figure 4]
- Direction: Determined by measuring the angle formed by the line joining its origin and termination and the line perpendicular to the median raphe. On the basis of direction rugae can be: forward directed/backward directed/perpendicular [Figure 5]
- Unification: is said to have occurred when two rugae joined at their origin or termination [Figure 6].
