They improve contact between food and taste receptors located on the dorsal surface of the tongue, resulting in better sensibility of taste.4,5 In recent years, several studies have been conducted related to the molecular basis of the formation of palatal rugae
.6,7,8 The pattern may vary from simple to complex and is largely governed by the genetic factors.
This was done primarily to find out whether the shape and number of rugae
have an association with PA and other palatal dimensions.
31.3% knew about the characteristic Rugae
pattern specific for individuals.
are the asymmetrical and irregular elevations of the mucosa.
The SEM of the embryonic whorls of Helminthoglypta greggi shows ornamentation with rounded elongated papillae arranged in apically ascending, well-spaced, rather ill-defined, spiral rows separated by cross-rows of numerous short rugae
Studying additional biometric traits such as the palatal rugae
pattern to differentiate between identical twins is an important focus in biometrics and forensic odontology .
Head: supraclypeal area smooth, frons to vertex with fine, irregular but continuous carinae, in frontal view those in median third parallel, those in lateral areas diverging posteriorly; in lateral view eye about half the length of the distance between the eye and mandibular insertion, eye with 12 facets, area between eye and mandibular insertion without distinct carinae or rugae
. Mesosoma: pro- and mesonotum with 13 fine, parallel, continuous carinae, only slightly irregular, interspaces smooth, at least twice as wide as carinae; sides of pronotum with 6 irregular fine carinae, interspaces smooth; posterior area of mesopleuron and anterior area of metapleuron with 5 carinae, slightly rugose between carinae; propodeal spines triangular, shorter than anterior dorsal face of petiole.
Head and pronotum with deep pits and rugae
; wings without dark bands, rosy red at base, apically smoky.....
1C, D): With hypandrium narrow, straight; gonostyle 1.5 x length of gonocoxite; gonostyle basally with a cluster of lateral setae, with scattered spiniform sensilla along length; gonocoxal condyles triangular in dorsal and ventral views; aedeagus asymmetrical; basiphallus broad in dorsal view, connected laterally to parameres by parameral-aedeagal membrane, medially to distiphallus, morphodorsally with pointed connection to ventral epandrial plate; distiphallus comprised of two lateral phallomeres and morphodorsal phallic membrane forming duct; distiphallus twisted 90[degrees] to the left; parameres triangular with a morphoventral projection carrying small, verruca-like rugae
; epandrium (Fig.
Although DNA comparisons and finger print analyses are common techniques which are employed to ensure fast and secure identifications, there are certain crime scenarios where other supplemental aids like lip prints, palatal rugae
pattern, bite marks etc.
Swelling was noted extending anteriorly from palatal rugae
and posteriorly upto the maxillary tuberosity of size 5x6 cm (figure 2) and laterally obliterating the buccal vestibule in relation to 25,26,27 region.
They were divided into two distinct population groups: Group A (edentulous patients with full upper removable dentures), Group B (dentulous without upper removable partial dentures), which underwent examination of the forms of the palatal rugae
using the method described by Martins-dos-Santos (1946), in order to verify the applicability and possibilities of success in examining the edentulous and dentulous arches.
