This study investigated the morphometric changes that occur in palatal rugae during orthodontic treatment. The potential impact of these changes on the individuality of the palatal rugae patterns and on the use of palatal rugae patterns in human identification was also explored. Fifty pairs of pre- and post-orthodontic treatment dental casts were used. The palatal rugae patterns were compared b...

A prospective longitudinal study in 75 growing cats was conducted to evaluate palatal soft-tissue expansion in cleft lip and palate surgery. In 31 cats, palatal scars were induced by simulated Langenbeck surgery at the age of 8 weeks. At the age of 14 weeks, custom-made tissue expanders were inserted in 61 animals. Tissue expansion was performed by weekly inflation in 33 cats (16 without and 17...

Background and purpose: Transverse problems in the maxilla (high arched- narrow hard plates) can cause respiratory disorders. Palatal expansion can be helpful in this way. The present study aimed at evaluating the effect of bone borne expansion and tooth borne palatal expansion on airway volume. Materials and methods: A review study was performed by search in Google Scholar, Scopus, PubMed, Em...

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...

objective: To determine the number and pattern of palatal rugae in Nepalese subjects and to find the association of gender with the number and pattern of palatal rugae. Materials & Method: 200 Nepalese subjects comprising of 100 male and 100 female were randomly selected and their maxillary casts were examined for the palatal rugae length applying the classification proposed by Thomas and Kotze...

We studied the prevalence and clonality of high-level gentamicin-resistant enterococci (HLGRE) in a Dutch university hospital. Of 238 enterococcal strains isolated from blood cultures between 1991 and 1997, 57 were HLGRE. Genomic analysis of these strains revealed 19 different genotypes, two of which were encountered more frequently [type A (12/57), type B (23/57)]. The spread of these types la...

Atypical P. vivax cases reported in Manaus municipality led us to detect a genetic isolate of P. vivax. Variable regions of SSUrRNA were examined from the initial time of infection and in the two recrudescences/relapses from a patient exhibiting chloroquine and primaquine resistance. A unique isolate, found at all stages of infection, suggests the presence of a clonal expansion.

OBJECTIVE This study was conducted to assess the accuracy of palatal rugae as a tool for human identification and to determine factors that may limit accuracy. This will serve as a potential basis for advising national health policy formulation on human identification as forensic rugoscopy is unexplored in sub-Saharan Africa. MATERIALS AND METHODS One hundred consenting participants were recr...
