Ameloblastic fibroodontoma (AFO) is a rare entity of mixed odontogenic tumors and frequently arises from posterior portion of the maxilla or mandible in first two decades of life. Herein, a 35-year-old woman with a noncontributory medical history who presented with a progressive left maxillary toothache, left maxillary first molar tooth mobility, and swelling in the left maxillary molar area for the last 2 months was reported. Radiologically, a tumor that originated from periapical area of the second mature molar teeth of maxilla was seen and additively unerupted tooth was not detected. The histopathologic examination revealed AFO. The patient is disease-free for five years after treated with limited segmental alveolectomy combining with Caldwell-Luc procedure.

Maxillary sinus floor augmentation (also termed sinus lift, sinus graft, sinus augmentation or sinus procedure) is a surgical procedure which aims to increase the amount of bone in the posterior maxilla (upper jaw bone), in the area of the premolar and molar teeth, by lifting the lower Schneiderian membrane (sinus membrane) and placing a bone graft [2]. When a tooth is lost the alveolar process begins to remodel. The vacant tooth socket collapses as it heals leaving an edentulous (toothless) area, termed a ridge [3]. This collapse causes a loss in both height and width of the surrounding bone. In addition, when a maxillary molar or premolar is lost, the floor of the maxillary sinus expands, which further diminishes the thickness of the underlying bone. Overall, this leads to a loss in volume of bone that is available for implantation of dental implants, which rely on osseointegration (bone integration), to replace missing teeth [1]. The goal of the sinus lift is to graft extra bone into the maxillary sinus, so more bone is available to support a dental implant. A Special form of Reconstruction of bone, especially changing the vertical structure of the maxillary Sinus floor in the upper jaw and the establishment of the mucous membranes of Sinusitis purpose of dental implant called Sinuslift [4, 5, 6 & 8]. Distance-maxillary sinus is often so low that an implant can not be included in stable long enough. With the incorporation of bone material or bone grafting, maxillary sinus floor, ‘grow’ and that this level can be implanted implants safe. Sinuslift distinguish Extern and Intern [9,10].

Abstract Background The proximity of the maxillary sinus floor to the maxillary molar roots increases the probability of oroantral communication on conducting any surgical or endodontic procedure in the involved area. The aim of this study is to evaluate the relationship between each maxillary molar root and maxillary sinus floor using cone beam computed tomography. Predicting the probability of protrusion of each root into the sinus will consequently predict the probability of occurrence of the oroantral fistula in a sample of the Egyptian population. Results The total number of roots located outside the sinus was 121 (35.3%), while those contacting the sinus floor were 80 (23.3%) and those intruded the sinus were 141 (41.2%). The percentage of root intrusion into the sinus in males (56.9%) was significantly (p = 0.01) higher than females (42.9%). The probability of root intrusion in the left molars (54.2%) was non-significantly (p = 0.067) higher than that of the right side (44.3%). As for the type of tooth, the second molar showed the highest probability of root intrusion into the sinus (55.3%) followed by the third molars (52.6%) then the first molars (40.9). According to the type of root, the mesiobuccal root showed the highest probability of intrusion into the sinus (50.9%) followed by the palatal root (49.1%) then the distobuccal root (47.4%). However, the difference in both type of tooth and type of root was statistically non-significant (p = 0.051 and 0.869 respectively). As for the individual root with the highest probability of intrusion, the mesio-buccal root of the right third molar is the most frequent root to intrude the sinus (71.4%) and the mesio-buccal root of the right first molar is the least frequent (22.7%). Conclusions In a sample of the Egyptian population, males exhibit higher probability of root protrusion into the sinus than females. The side and type of tooth are of higher impact on the probability of its intrusion into the sinus compared to the type of root. Left second molars are at a higher risk of oroantral communications on surgical or endodontic procedures compared to other molars due to its highest probability of intrusion into the sinus.

Cutaneous Myiasis

Infestation of any dead or necrotic tissues by the larvae of flies (maggots) is myiasis. This form of habitation is not restricted to any particular tissues in the body and can occur anywhere. However, myiasis at the surgical stoma site is very rare. We present a 55-year-old woman diagnosed with metastatic carcinoma of the oesophagus who underwent feeding gastrostomy (FG). The patient later presented with worms at the FG site. We removed the FG tube, cleared all the maggots, thoroughly cleaned the wound and placed a new FG tube. Although its occurrences have been reported enough in medical history, there are only two documented cases of percutaneous endoscopic gastrostomy stoma site myiasis. Hence, we present the first case in the literature of cutaneous myiasis around an FG stoma site.

Background The phenomenon of recirculation involves the circulation of mucous secretion between the natural ostium and other openings and is observed mainly after surgery when the surgical opening is not connected. Methods Seven patients with a mucous stream transporting into an accessory ostium, as found during endoscopic examination, were entered into study. The coronal computed tomogram findings of the mucous recirculation were analyzed at three levels: anterior, middle, and posterior portion of it. Results The anterior portion was visualized at the level of the natural ostium in five patients. The middle portion inside the maxillary sinus was visible in six cases. The posterior portion was visualized at the level of the accessory ostium in five patients. Among the axial scans, mucous rings were visible in two patients. Conclusions The primary mucous recirculation between the natural and accessory openings is shown as a ring structure in coronal computed tomogram scans.

The molecular events of odontogenic induction are beginning to be elucidated, but until now nothing was known about the molecular basis of the patterning of the dentition. A role for Dlx-1 and Dlx-2 genes in patterning of the dentition has been proposed with the genes envisaged as participating in an ‘odontogenic homeobox gene code’ by specifying molar development. This proposal was based on the restricted expression of the genes in molar ectomesenchyme derived from cranial neural crest cells prior to tooth initiation. Mice with targeted null mutations of both Dlx-1 and Dlx-2 homeobox genes do not develop maxillary molar teeth but incisors and mandibular molars are normal. We have carried out heterologous recombinations between mutant and wild-type maxillary epithelium and mesenchyme and show that the ectomesenchyme underlying the maxillary molar epithelium has lost its odontogenic potential. Using molecular markers of branchial arch neural crest (Barx1) and commitment to chondrogenic differentiation (Sox9), we show that this population alters its fate from odontogenic to become chondrogenic. These results provide evidence that a subpopulation of cranial neural crest is specified as odontogenic by Dlx-1 and Dlx-2 genes. Loss of function of these genes results in reprogramming of this population of ectomesenchyme cells into chondrocytes. This is the first indication that the development of different shaped teeth at different positions in the jaws is determined by independent genetic pathways.

ABSTRACTAmeloblastic fibroma (AF) is a rare odontogenic tumour of the jaw which usually occurs in the first 2 decades of life. The common clinical manifestation is a slow-growing swelling. We report a case of a 16-year-old male patient presenting with extensive AF of the mandible. He underwent a conservative enucleation. The tumour recurred 2 years after the initial surgery, requiring the second enucleation.The patient has continued to be followed closely and has been disease-free for 4 years. Recent evidence suggests that the recurrent rate of AF is relatively high, and malignant transformation of AF may occur after recurrences or multiple surgeries. A conservative treatment approach with close surveillance is recommended. Anatomical limitations should be taken into account, especially when enucleation of AF in the posterior portion of the jaw is performed. Current surgical pathologic issues of the tumour are also discussed. (Eur J Dent 2009;3:224-228)
