BACKGROUND Palatal rugae (PR) are asymmetrical irregular elevations, recorded during maxillary cast fabrication, that can be used for identification purpose if previous comparative sources are available. AIM This study investigated uniqueness of PR patterns in relation to gender, palatal vault forms, and ABO blood groups in three (North-East [N-E], Northern and Western) populations of India. ...

OBJECTIVE To (1) evaluate the stability of palatal rugae as landmarks for superimposition of dental casts and (2) establish a three-dimensional superimposition method of maxillary dental casts for analyzing orthodontic tooth movement. MATERIALS AND METHODS The sample consisted of dental casts obtained from 10 patients treated with extraction of bilateral maxillary first premolars and placemen...

Aim: To determine the most common rugae pattern and to find if it has any association with dental arch form or malocclusion. Study Design setting: It was a retrospective cross-sectional study conducted using records of 200 patients visiting Orthodontic Outpatient department Bahria University Medical Dental College. Methodology: Number, size, orientation palatal were assessed on plaster models. ...

=Abstract=Sprague-Dawley rat fetuses ranging from 15to 19-day of gestational age, were studied with their rugae morphogenesis a t the light microscopic level. The distribution of collagen fibers in the palatal mesenchyme was analyzed. In addition, an attempt to evaluate the role of collagen fibers in rugae development was made. The specimens were H-E stained and collagen fiber stained according...

Palatine rugae are the characteristic soft tissue folds on the anterior third of the palate. These are highly individual and consistent in shape throughout life. Palatine rugae are important as it can be useful in many ways. When identification of an individual by other methods as finger print ,lip print etc is inconclusive, palatal rugae may be considered as an alternative source of informatio...

Aim: To assess the reliability and validity of morphometric features on 3D digital models produced by scanning maxillary dental casts Malaysian Malay subjects. Methods: Dental 20 subjects were scanned using a laser scanner (Next Engine Inc., Santa Monica, California, USA). The palatal rugae assessed resulting 3-Matic Research 9.0 software (Materialise NV, Heverlee, Belgium). assessments repeate...

Background:Rugae are the anatomical folds that are located on the anterior third of palate behind the incisive papillae. They are also known as "Plica palatine," and the study of these patterns is called palatoscopy. It can be used in various fields such as sex determination, orthodontics and forensic odontology Aim And Objective:The objective of this article is to analyse different palatal rug...

Metazoans are largely made of repeated parts, and metazoan evolution is marked by changes in the number of these parts, called meristic evolution. Understanding the mechanisms associated with meristic changes is thus a critical issue to evolutionary developmental biology. Palatal rugae are sensory ridges regularly arranged on the hard palate of mammals. They develop sequentially following mesio...

BACKGROUND Human identification is one of the most challenging subjects that man has been confronted with. The fingerprints and DNA comparison are the most commonly used techniques in human identification. Palatoscopy is one of the recently developing methods to identify a victim-based on the palatal rugae pattern. AIMS AND OBJECTIVES The aim of the study was to analyze the different rugae pa...

Transverse palatine folds or palatal rugae (PR), are asymmetrical and irregular elevations of the mucosa in the anterior third of the palate arranged in a transverse direction on each side of the medial palatal raphae and behind the incisive papilla (IP), located in the mid-sagittal plane [1,2]. Developmentally, palatal rugae are formed in the third month in utero from the hard connective tissu...
