BACKGROUND Forensic odontology plays important role in identification of human remains in mass disasters such as air crash, tsunami, and accidents. Palatal rugae act as an ideal requisite for human identification as they are present in all victims and are resistant to changes such as aging and trauma. The study aimed to analyze differences in shape and number of palatal rugae in population from...

several appliances have been used for palatal expansion for treatment of posterior cross bite. the purpose of this study was to evaluate the stress induced in the apical and crestal alveolar bone and the pattern of tooth displacement following expansion via removable expansion plates or fixed-banded palatal expander using the finite element method (fem) analysis.two 3d fem models were designed ...

AIM To evaluate retention of complete denture base with different types of posterior palatal seals. MATERIAL AND METHODS Ten male patients between the age group of 50 years to 60 years were selected for the study. After the primary and secondary impressions were taken, five casts were made including a cast without posterior palatal seal, a cast with single bead posterior palatal seal, a cast ...

The purpose of this study was to determine whether symphysis morphology could be used as a predictor of the direction of mandibular growth and to assess growth changes of the symphysis. Cross-sectional data included lateral cephalometric radiographs of 115 adults (58 women, 57 men) with the longitudinal sample a subset of 62 subjects (30 females, 32 males) at four age groups. The direction of m...

This study used Functional Data Analysis (FDA) to analyse tongue articulation dynamics, more specifically the height and frontness of the tongue body and tip in the palatal vowels /i:, y:, 0ff:/ of two varieties of Swedish. Articulatory data were collected from nine speakers each of Gothenburg and Malmöhus Swedish. Standard z-score transformations were used for speaker normalisation. Results sh...

Introdouction: Variations in root canal morphology pose a challenge for successful endodontic treatment. The root canal anatomy of the maxillary first molar has been often described as three roots with four canals (two mesiobuccal, one distobuccal, and one palatal). The occurrence of two palatal canals in one palatal root is quite rare. This report represents the case of a maxillary first molar...
