1/7. Spontaneous uprighting of permanent tooth germs after elimination of local eruption obstacles.Four clinical cases are presented to demonstrate the self-correcting potential of aberrant tooth germs after the elimination of eruption obstacles (in 2 cases cysts, in 2 other cases severely infraoccluded primary teeth). In the case of the submerging deciduous teeth, the tilted adjacent teeth were orthodontically uprighted after the surgical procedure. Possible causative mechanisms are discussed.- - - - - - - - - - ranking = 1keywords = tooth (Clic here for more details about this article) |
2/7. The lateral periodontal cyst: aetiology, clinical significance and diagnosis.The lateral periodontal cyst (LPC) is a relatively uncommon but widely recognized odontogenic cyst of developmental origin. It is found mostly in adults and has no sex predilection. LPC is usually discovered during routine radiographic examination, is located mainly between the roots of vital mandibular canines and premolars, and seldom causes pain or other clinical symptoms. The defect appears on radiographs as a round or teardrop-shaped, well circumscribed radiolucency. Due to its location it can easily be misdiagnosed as a lesion of endodontic origin. In this paper, two cases of lateral periodontal cysts are presented. In the first case, the patient (woman, 62 years old) complained of an asymptomatic gingival swelling in the region between the right maxillary canine and premolar. The radiographic examination revealed a well circumscribed radiolucency with a radiopaque margin between the roots of the canine and premolar. The adjacent teeth had vital pulp. Surgical enucleation of the lesion was performed and the histological examination revealed that the lesion was a "lateral periodontal cyst of developmental origin". In the second case, the patient (women, 44 years old) complained of a swelling in the area of tooth 32. During radiographic examination a well circumscribed radiolucency between the roots of the lateral incisor and the canine was discovered. Surgical enucleation of the lesion was performed and the histological examination revealed that the lesion was a "lateral periodontal cyst of developmental origin".- - - - - - - - - - ranking = 0.2keywords = tooth (Clic here for more details about this article) |
3/7. Mandibular buccal bifurcation cyst: enucleation without extraction.The mandibular buccal bifurcation cyst (MBBC) is a cystic lesion, which occurs on the buccal surface of the permanent mandibular first molar in children around 6-8 years old. Treatment of the cyst has been controversial: extraction of the involved tooth and enucleation of the cyst, or only enucleation, without extraction. The aim of this article is to familiarize oral and maxillofacial surgeons with this entity and the appropriate treatment approach. The diagnostic features of MBBC are described and the treatment approach in five patients with a total of seven cysts is presented. Two cases were identified in identical twins. Enucleation of the cyst without extraction of the involved tooth is the treatment of choice when the available data and experience in treating MBBC are considered.- - - - - - - - - - ranking = 0.4keywords = tooth (Clic here for more details about this article) |
4/7. Orofacial features of Scheie (Hurler-Scheie) syndrome (alpha-L-iduronidase deficiency).Scheie syndrome is a rare inborn error of metabolism, a mucopolysaccharidosis in which deficiency of the lysosomal enzyme alpha-L-iduronidase leads to tissue accumulation of mucopolysaccharides. Scheie syndrome is a forme fruste of Hurler syndrome (gargoylism), and some patients have the phenotype of Hurler-Scheie compound syndrome. The craniofacial abnormalities include coarse facies, mandibular condylar hypoplasia, retarded tooth eruption, and cystic jaw radiolucencies--particularly about the molars. Corneal clouding may lead to blindness but, in contrast to some other mucopolysaccharidoses, mental handicap is rare in Scheie syndrome. Cardiac valve incompetence is common, as are recurrent respiratory infections. Two brothers with Hurler-Scheie syndrome are presented and the oral and systemic complications each patient had described. The syndrome is discussed with particular reference to the orofacial features.- - - - - - - - - - ranking = 0.2keywords = tooth (Clic here for more details about this article) |
5/7. Computed tomography in the evaluation of postoperative maxillary cysts.Twenty-two cases (34 sides) of postoperative maxillary cysts evaluated with axial and coronal computed tomograms were reviewed. Precise characteristics pertaining to the extent of maxillary sinus involvement, loculation, presence of septae, bony perforation, and associated cystic projection or extension into adjacent structures were determined. Of the 34 sides, 13 cysts involved the sinus completely. Twelve were multilocular. Thirteen exhibited incomplete septae. Perforations were most frequent in the anterolateral and medial bony walls (28 and 27, respectively); however, the 14 posterolateral wall perforations showed a higher percentage of cystic projection into adjacent structures. Ethmoid extension was seen on two sides, orbital extension on one. Nine sides showed tooth roots communicating with the cyst. The routine use of computed tomography in the evaluation of this type of cyst is proposed.- - - - - - - - - - ranking = 0.2keywords = tooth (Clic here for more details about this article) |
6/7. Importance of clinical examination and diagnosis. A case of dens invaginatus.A case report is presented that shows a radiolucent lesion between the maxillary left lateral incisor and canine tooth, both of which were vital. The cause of the lesion was initially unclear. The patient was to be treated surgically, however, precise examination made it clear that the cause of the radiolucent lesion was due to the exposure of a second canal because of attrition of the lateral incisor crown. The final diagnosis of the tooth was dens invaginatus. This case highlights the importance of careful examination and correct diagnosis.- - - - - - - - - - ranking = 0.4keywords = tooth (Clic here for more details about this article) |
7/7. An ossifying fibroma presenting as Stafne's idiopathic bone cavity.The purpose of this paper is to present a case of a fibro-osseous lesion which was diagnosed as an ossifying fibroma rather than a cemento-ossifying fibroma because of its location away from the tooth bearing parts of the jaw and the absence of cemental tissue in the excised specimen. Its location and features on a panoramic radiographic made Stafne's idiopathic bone cavity a possible diagnosis.- - - - - - - - - - ranking = 0.2keywords = tooth (Clic here for more details about this article) |
