Abstract
ABSTRACTWhile impaction of tooth is widespread, multiple impacted teeth by itself is a rare condition and often found in association with syndromes such as cleidocranial dysplasia or Gardner’s syndrome. A light of radiographic examination, we describe three Turkish young males with multiple impacted teeth who didn’t possess any systemic conditions or syndromes involving both jaws. The first patient, a 21-year-old young male, had 16 unerupted teeth and 5 unerupted supernumerary teeth. The second patient with totally edentulous mandible, a 20-year-old young male, had 31 unerupted teeth. The third patient, a 21-year-old young male, had 22 unerupted teeth and 4 unerupted supernumerary teeth. Based on the clinical presentation, radiographic examination and histopathological studies, this paper discusses the differential diagnosis and management of such cases. (Eur J Dent 2008;2:73-78)

Abstract
Real-time (RT) determination of the health of in vitro tissue-engineered constructs prior to grafting is essential for prediction of success of the implanted tissue-engineered graft. In addition, the US Food and Drug Administration requires specific release criteria in RT prior to the release of tissue-engineered devices for human use. In principle, assessing the viability and functionality of the cellular component can be achieved by quantifying the secretion of growth factors and chemokines of tissue-engineered constructs. Ex vivo-produced oral mucosa equivalents (EVPOMEs) were fabricated under thermally stressed conditions at 43 °C for 24 h to create a functionally compromised EVPOME. We used microchannel enzyme-linked immunosorbent assay to evaluate the functionality of the cellular component, oral keratinocytes, of stressed and unstressed EVPOMEs by measuring the release of vascular endothelial growth factor (VEGF), interleukin-8 (IL-8), human β-defensin 1 (hBD-1), and tissue inhibitor of metalloproteinase 1 and 2 (TIMP-1 and -2) into the spent medium, which was collected on the same day prior to graft implantation into severe combined immunodeficiency mice. Implanted EVPOMEs' histology on the seventh postimplantation day was used to correlate outcomes of grafting to secreted amounts of IL-8, hBD-1, VEGF, TIMP-1, and TIMP-2 from corresponding EVPOMEs. Our findings showed that significantly higher levels of IL-8, hBD-1, and TIMP-2 were secreted from controls than from thermally stressed EVPOMEs. We also found a direct correlation between secreted VEGF and IL-8 and blood vessel counts of implanted EVPOMEs. We concluded that measuring the constitutive release of these factors can be used as noninvasive predictors of healthy tissue-engineered EVPOMEs in RT, prior to their implantation.

Abstract
OBJECTIVE When a mandibular third molar is partially impacted in the soft tissue, it must be determined whether the extraction wound should be left partially open or completely closed. We hypothesize that a blood clot preserving a surgical wound with easily cleanable surfaces by primary closure and drain application would postoperatively minimize dry socket and/or alveolitis development. METHOD AND MATERIALS Twenty patients requiring bilateral extraction of partially soft tissue-impacted mandibular third molars in a vertical position were included in the study. The existence of dry sockets, alveolitis, pain, facial swelling, and trismus were evaluated on the second, fifth, and seventh days of the postoperative period. RESULTS On the second day, pain, trismus, and swelling were higher in the drained group; however, pain reduced progressively in the drained group over time. There were no cases of dry sockets or alveolitis except for a single patient on the seventh day in the drained group over the 7-day study period. On the other hand, in the secondary closure group, the number of dry sockets was 8 (40%) on the second day. The number of alveolitis was 10 (50%) on the fifth day and 4 (20%) on the seventh day. CONCLUSION Closed healing by drain insertion after removal of partially soft tissue-impacted third molars produces less frequent postoperative dry sockets and/or alveolitis development than occurs with open healing of the surgical wound. In cases with a risk of alveolitis development (lack of oral hygiene, immunocompromised patients, etc), it can be avoided with the "kiddle effect" and related undesired complications by implementing closed healing with drain insertion.

Abstract
OBJECTIVE The aim of this study is the histological and immunohistochemical evaluation of ex vivo produced oral mucosal equivalents using keratinocytes cultured by direct explant technique. MATERIAL AND METHODS Oral mucosa tissue samples were obtained from the keratinized gingival tissues of 14 healthy human subjects. Human oral mucosa keratinocytes from an oral mucosa biopsy specimen were dissociated by the explant technique. Once a sufficient population of keratinocytes was reached, they were seeded onto the type IV collagen coated "AlloDerm" and taken for histological and immunohistochemical examinations at 11 days postseeding of the keratinocytes on the cadaveric human dermal matrix. RESULTS Histopathologically and immunohistochemically, 12 out of 14 successful ex vivo produced oral mucosa equivalents (EVPOME) that consisted of a stratified epidermis on a dermal matrix have been developed with keratinocytes cultured by the explant technique. CONCLUSION The technical handling involved in the direct explant method at the beginning of the process has fewer steps than the enzymatic method and use of the direct explant technique protocol for culturing of human oral mucosa keratinocyte may be more adequate for EVPOME production.

Abstract
Neurosensory deficits are the most common complication following orthognathic surgery. Le Fort I and sagittal split ramus osteotomies have been widely studied but there is a lack of data about the neurosensory alterations resulting from anterior maxillary osteotomy (AMO). This paper evaluates the neurosensory alterations in cutaneous regions including lower eyelid, cheek, nose, upper lip and vestibular and palatal mucosal areas using simple clinical tests following AMO performed with Bell's incision so patients can be properly informed about the extent of sensory loss and its rate of recovery following AMO. Twenty-four sides of 12 patients (eight females; four males) with a mean age of 14.20 ± 1.86 years (range 12-17 years) were examined. Pin prick sensation, light touch sensation, static and dynamic two-point discrimination tests were used. Following AMO, vestibular mucosa, upper lip, nose and cheek were the most commonly affected sites. No alterations were detected in lower eyelid and palatal mucosa. The neurosensory deficits in cheek, nose and upper lip resolved 10 days after surgery. The vestibular mucosa showed normal sensation on day 30. In conclusion, following AMO, neurosensory alterations can occur, but it will resolve spontaneously in 30 days.
