talon cusp is a rare developmental anomaly that occurs most commonly on the lingual side of the incisors. occurrence of the labial talon cusp is rare in the dental literature. till date only seven cases of isolated nonsyndromic labial talon cusps have been reported in the maxillary permanent dentition. however, a few cases of syndromic labial talon cusps and faciolingual talon cusps have been r...

Because of their impact on human and veterinary health, there is considerable interest in understanding how Culicoides use olfactory cues in host location. The adequate chemical stimulus for sensilla located on the maxillary palps was determined for several species of female Culicoides. Electrophysiological studies identified and characterized the sensory neurons on Culicoides maxillary palps t...

in this investigation the thickness of enamel in the gingival, middle, and incisal thirds of the labial surface of the anterior teeth were measured regarding preparation of the teeth for porcelain laminate veneers.part one, 20 extracted intact human maxillary central and lateral incisors ten of each were selected. the teeth were imbedded in autopolimerize acrylic resin. cross section was prefor...

Discrepancy in the labial gingival margin of the maxillary incisors poses a major aesthetic problem. Orthodontic extrusion can improve the aesthetic problem caused by gingival margin levels before restoration. In these case reports, orthodontic extrusion was performed with palatal circumferential supracrestal fiberotomy for improving the discrepancy of the labial gingival margin. Two years post...

Many treatment plans require a dental practitioner to maintain the entire labial cortical plate of bone when removing an anterior maxillary tooth. A tooth with an undermined root secondary to an endodontic perforation or internal (Idiopathic) resorption can present a surgical challenge to the general practitioner. This article describes a new technique for extracting a severely undermined anter...

The effect of diet on the number of gustatory and olfactory sensilla was investigated in locusts. Insects fed for the final two stadia on nutritionally adequate synthetic foods have fewer sensilla on the maxillary palps and antennae than insects fed on the usual rearing diet of seedling wheat. This effect was seen irrespective of the nutritional balance of the foods and was independent of the c...
