| The aim of this study was to examine the morphometric characteristics of the infraorbital foramen of skulls of people living in modern society and in the late Byzantine period, to ascertain the symmetry or asymmetry of the two halves of the skulls by measuring the linear distance between various landmarks, to evaluate at the conformity between the infraorbital foramen and the golden ratio by calculating the ratios between these linear distances, and to set out the differences or similarities between the skulls of these different periods. It was found in the study that the morphometric characteristics of the infraorbital foramen in skulls of the modern period were 47.05 % circular, 41.17 % oval and 11.76 % atypical (semilunar and triangular) on the right,... |

| This study proposes to measure and compare anthropometric measurements between toothed and toothless maxillas. 26 human skulls were used with: 13 toothed and 13 toothless maxillas. The measurements were made between the distances of the alveolar ridge (AR): the anterior nasal spine (ANS), to the incisive foramen (FI) and the palatine foramen, greater (FPMA) and lower (FPME) on both sides by two evaluators. The data obtained showed that the average of the measurements were correspondingly higher in toothed maxillas than in toothless, for all measurements in any one of the evaluators. The AR-ANS (p = 0.001), IF-AR (p = 0.006), AR-FPMA right (p = 0.001) and AR-FPMA left (p <0.001) and AR-FPME on both sides (p = 0.001) demonstrating significant differences... |

| The centripetal resorption of maxilla is a continuous process after tooth loss. For treatment of deficient bone sites, autologous bone grafts may be used, as an alternative, biomaterials can be applied which do not require intra or extraoral donor sites. The present report describes the use of occlusive barriers and cortical particulate allograft in transverse maxillary defects. This surgical approach was performed in five patients (4 females and 1 male, aged 20 to 37 years). Clinical results show that sufficient hard tissue was formed to allow implant born rehabilitation in the former insufficient bone sites. Histological evaluation revealed small amounts of newly formed bone with a predominance of collagen fibrous tissue and mature bone with very little... |

| The centripetal resorption of maxilla is a continuous process after tooth loss. For treatment of deficient bone sites, autologous bone grafts may be used, as an alternative, biomaterials can be applied which do not require intra- or extraoral donor sites. The present report we describe the use of anorganic bovine bone (ABB) based on three case reports under different modes: Membrane, rigid barrier and connective tissue graft. Clinical results show that under all conditions, sufficient hard tissue was formed to allow implant born rehabilitation in the former insufficient bone sites. Histologic evaluation revealed trabecular bone in an almost mature matrix with resting particles of ABB. Depending on the original site situation, two step rigid occlusive... |

| Calcium along with phosphorus and carbonate imparts hardness and strength to skeletal system. Most of the human studies in this context are based on informations in postnatal life. There are different theories to explain the manner in which the matrix of bone becomes impregnated with the two inorganic salts, calcium phosphate and calcium carbonate. In our study, 29 human foetuses were obtained from the museum section of Department of Anatomy, J .N. Medical College, Aligarh, and divided into five groups. Maxillae were cleaned by separating the soft tissue and dissolved in concentrated nitric acid to determine calcium. Results were analysed by using Student's 't' test. The most striking feature of our findings was a reduction in aforementioned relative... |

| BACKGROUND: Acetylcholine (ACh) is known to be a key neurotransmitter in the central and peripheral nervous systems, which is also produced in a variety of non-neuronal tissues and cell. The existence of ACh in maxilla in vivo and potential regulation role for osteogenesis need further study. RESULTS: Components of the cholinergic system (ACh, esterase, choline acetyltransferase, high-affinity choline uptake, n- and mAChRs) were determined in maxilla of rat in vivo, by means of Real-Time PCR and immunohistochemistry. Results showed RNA for CarAT, carnitine/acylcarnitine translocase member 20 (Slc25a20), VAChT, OCTN2, OCT1, OCT3, organic cation transporter member 4 (Slc22a4), AChE, BChE, nAChR subunits α1, α2, α3, α5,... |

| Chronic osteomyelitis of maxilla and mandible is rare in industrialized countries and its occurrence in developing countries is associated with trauma and surgery, and its microbial etiology has not been studied thoroughly. The aim of this investigation was to evaluate the microbiota associated with osteomyelitis of mandible or maxilla from some Brazilian patients. After clinical and radiographic evaluation, samples of bone sequestra, purulent secretion, and biopsies of granulomatous tissues from twenty-two patients with chronic osteomyelitis of mandible and maxilla were cultivated and submitted for pathogen detection by using a PCR method. Each patient harbored a single lesion. Bacterial isolation was performed on fastidious anaerobe agar supplemented... |

| Literature regarding analysis of infraorbital foramen and canal exists in adult but it is scanty in foetuses.Morphometric measurements were performed in sixty maxillae dissected out from thirty human foetuses.The latter were divided into five groups on the basis of age i.e. groups I(<17 weeks IUL),II (17-20 weeks IUL), III (21-25 weeks IUL),IV (26-30 weeks IUL) and V (>30 weeks IUL).Four parameters considered were length of infraorbital foramen and canal and width of anterior and posterior ends of infraorbital foramen. Range of measurements between the smallest foetal group to largest foetal group for length of infraorbital foramen and canal and width at the anterior and posterior ends of infraorbital foramen were 4.01mm to 6.00 mm,0.67 mm to... |

| A detailed knowledge of the anatomic morphometry of infraorbital groove, canal and foramen was necessary for a surgeon while performing maxillofacial surgery and regional block anaesthesia. Modern surgical procedures as well as anaesthesia require more precise understanding of the surrounding anatomy. The aim of the study was to establish morphometrically the infraorbital foramen size and location in human foetuses, the area where this information was scanty. Sixty maxillae were dissected out from thirty human foetuses. The latter were divided into five groups on the basis of age i.e. groups I(<17 weeks IUL),II (17-20 weeks IUL), III (21-25 weeks IUL),IV (26-30 weeks IUL) and V (>30 weeks IUL). Four parameters including transverse diameter and... |
