Tooth intrusion is the most common trauma during early infancy. Primary maxillary central incisors are the most affected teeth. There are a few treatment approaches which depend upon the severity of the trauma, and the treatment must be managed professionally. In this case report, a 3-year-old girl with a history of trauma 40 days before referring to our pediatric clinic is presented. Deciduous...

decapentaplegic (dpp), the Drosophila ortholog of BMP 2/4, directs ventral adult head morphogenesis through expression in the peripodial epithelium of the eye-antennal disc. This dpp expressing domain exerts effects both on the peripodial epithelium, and the underlying disc proper epithelium. We have uncovered a role for the Jun N-terminal kinase (JNK) pathway in dpp-mediated ventral head devel...

Non-Hodgkin's lymphoma (NHL) belongs to a group of lymphoid neoplasms that is diverse in manner of presentation, response to therapy and prognosis. Usually the oral manifestations of NHL are secondary to a more widespread involvement throughout the body. Though primary intraoral lesions in NHL are uncommon, it is important to be aware of them, since intraoral manifestations are the presenting s...

In the present study, some morphological structures of antennae, maxillary palps and caudal setae of fourth instar larvae of laboratory-reared phlebotomine sand flies (Lutzomyia longipalpis, L. migonei, L. evandroi, L. lenti, L. sericea, L. whitmani and L. intermedia) of the State of Ceará, Brazil, were examined under scanning electron microscopy. The antennal structures exhibited considerable ...

Carbon dioxide (CO2) elicits different olfactory behaviors across species. In Drosophila, neurons that detect CO2 are located in the antenna, form connections in a ventral glomerulus in the antennal lobe, and mediate avoidance. By contrast, in the mosquito these neurons are in the maxillary palps (MPs), connect to medial sites, and promote attraction. We found in Drosophila that loss of a micro...

The primary defence against mosquitoes and other disease vectors is often the application of a repellent. Despite their common use, the mechanism(s) underlying the activity of repellents is not fully understood, with even the mode of action of DEET having been reported to be via different mechanisms; e.g. interference with olfactory receptor neurones or actively detected by olfactory receptor n...

The Drosophila homeotic gene proboscipedia (pb: HoxA2/B2 homolog) is required for adult mouthparts development. Ectopic PB protein expression from a transgenic Hsp70-pb minigene (HSPB) results in transformation of adult antennae to maxillary palps. In contrast, most tissues appear refractory to PB-induced effects. To study the basis of homeotic tissue specificity we are isolating and studying m...

STATEMENT OF THE PROBLEM The use of miniscrews has expedited the true maxillary incisor intrusion and has minimized untoward side effects such as labial tipping. PURPOSE The aim of this study was to assess the stress distribution in the periodontal ligament of maxillary incisors when addressed to different models of intrusion mechanics using miniscrews by employing finite element methods. The...

This case report presents the non-surgical orthodontic camouflage treatment of an 18-year-old male patient with skeletal Class III asymmetry and severe anterior open bite. The bite was corrected by extrusion maxillary mandibular teeth clockwise counterclockwise rotation occlusal plane, respectively, using intermaxillary elastics between posterior buccal miniscrews canines vertical canines. dent...
