Palatal rugae patterns have unique characteristics and have been proposed as an alternative method to establish identity when other means, such as fingerprints and dental records, are not attainable. This study was conducted to determine the morphological characteristics of palatine rugae and to assess the existence of side asymmetry in them in Sudanese Arabs. It also assesses the possibility o...

BACKGROUND The associations between the length and morphological shape-related characteristics of palatal rugae have not been fully explored. OBJECTIVE We aimed to assess the possible association among various geometric configurations of the palatal rugae in an adult population. MATERIALS AND METHODS The maxillary dental casts of 217 non-growing subjects (95 males, 122 females, mean age 25....

INTRODUCTION This study was conducted to compare the rugae patterns between two major ethnic groups in Nigeria to establish any peculiarities. This will serve as basis for population identification especially in mass disasters involving individuals of different races or ethnicities. METHODS One hundred consenting participants, 50 of south-western Yoruba ethnicity and 50 of south-eastern Igbo ...

The palatine rugae have interested orthodontists not only because of their typical pattern of orientation but also because of their usefulness as a reference landmark in various dental treatment modalities. The pattern of orientation is formed by the 12th to 14th weeks of prenatal life and remains stable until the oral mucosa degenerates after death. The palatine rugae possess unique characteri...

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...

The study of identical twins can point out potential limitations in biometrics and forensic odontology. This case report presents three-dimensional (3D) palatal rugae analysis in monozygotic twins utilizing digital models obtained directly by scanning the maxillary dental arch with the iTero® intraoral digital scanner. The results show that the rugae patterns contain related but not identical f...

Human identification is a major task undertaken in forensic sciences. Palato-rugoscopy is based on the principle that no two palates are the same. The study of palatine rugae and the study of fingerprints are sometimes complementary as they operate in similar methods based on same scientific basis. The study intends to describe the shape and gender distribution of the palatine rugae and their p...

This study was designed to investigate the prenatal development of the palatal rugae in the White Rat and to discuss the possible role played by the developing rugae in palatal shelf elevation. Extraction of embryos from twenty pregnant female rats was carried out in the 12th, 13th, 14th, 15th and 16th day of pregnancy. Four embryos from each age were decapitated and their heads were fixed and ...

Objective: The role of forensic science in establishing the personal identity is based on DNA analysis, finger print and dental analysis. When the forensic remains are decomposed making all these sources, unavailable palatal rugae served as an important aid as it is resistant to heat and placed deep inside the oral cavity in a secure environment. Thus, palatal rugae can be used as an adjunct in...

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...
