1/10. Recurrent buccal space abscesses: a complication of Crohn's disease.Oral features of Crohn's disease include ulcerations, lip fissuring, cobblestone plaques, and mucosal tags. We report the case of a 16-year old male patient with a 3-month history of abdominal pain, diarrhea, and oral ulceration. Clinical examinations revealed established intestinal lesions, a marked cobblestone appearance in the oral cavity, and an unusual pattern of presentation not previously reported in the literature: persistent, recurrent buccal space abscesses.- - - - - - - - - - ranking = 1keywords = abscess (Clic here for more details about this article) |
2/10. A conservative biopsy technique for periapical lesions.This paper presented a conservative technique for biopsy of periapical lesions. The case report demonstrated the insertion of a flexible microsurgical biopsy forceps through a labial sinus tract into a lesion for removal of specimens for histopathological evaluation. This limited tissue removal seemed to induce a change from a cyst to a granuloma, as well as stimulate a degree of repair.- - - - - - - - - - ranking = 643.66439719039keywords = periapical (Clic here for more details about this article) |
3/10. Simultaneous cortex bone plate graft with particulate marrow and cancellous bone for reliable closure of palatal fistulae associated with cleft deformities.OBJECTIVE: The purpose of this study was to evaluate the effectiveness of simultaneous cortex bone plate (CBP) graft with particulate marrow and cancellous bone (PMCB) graft for reliable closure of palatal fistulae associated with alveolar clefts. DESIGN: Following standard secondary bone graft preparation of the cleft site, CBP harvested from the medial iliac crest was inserted into the palatal deficiency. This was followed by suturing the palatal mucosa. PMCB was then packed between the cortical bone and the reconstructed nasal floor. SETTING: Ten consecutive patients with palatal fistula were operated on at tokyo Medical and Dental University Hospital from 1998 to 2000. Primary palatal repair was performed in 7 out of 10 patients at our center and in 3 out of 10 patients at other hospitals. patients: Ten patients (6 boys and men, 4 girls and women) with a palatal fistula associated with an alveolar cleft were studied. Ages ranged from 12 to 26 years. INTERVENTIONS: All patients underwent simultaneous CBP graft with PMCB graft for closure of palatal fistula under general anesthesia. RESULTS: Complete closure of palatal fistulae were obtained in 8 out of 10 cases. A very small asymptomatic fistula remained in one patient. Total necrosis of the labial flap with a residual palatal fistula occurred in one patient. CONCLUSIONS: Simultaneous CBP graft with PMCB graft could be more reliable than PMCB alone for closure of a cleft associated palatal fistula.- - - - - - - - - - ranking = 0.14861631384162keywords = alveolar (Clic here for more details about this article) |
4/10. Clinical significance of the structural integrity of the superior aspect of the mandibular canal.BACKGROUND: Sparse data can be found regarding the structural integrity of the superior aspect of the mandibular canal. In many cases, the mandibular canal must be carefully evaluated prior to defining patient treatment. methods: In this case report, a 54-year-old patient presented with a periapical infection involving the mesial root of the mandibular right second molar (#31). Radiographic evaluation revealed that the periapical lesion extended from the apex of the tooth to the superior aspect of the mandibular canal. Upon surgical removal of the tooth, an apical communication between the extraction socket and mandibular nerve was located. A guided bone regeneration procedure was performed to protect the nerve from subsequent damage and to prepare the site for future implant placement. Implants were placed in the area approximately 5 months following the regenerative procedure. RESULTS: After implant placement, the patient experienced normal function and no mandibular symptomatology. Implants have been in function for the past 4 years. CONCLUSIONS: Many factors, both pathologic and developmental, can lead to a discontinuity of the superior aspect of the mandibular canal. Normally, a thin cortical plate of bone protects the nerve. When a lack of structural integrity of the canal roof is discovered, enucleation of a periapical infection or subsequent implant placement can lead to potential disruption of the nerve. Limited information is available regarding the integrity of this protective cover. This case report underscores the importance of proper clinical diagnosis before implant placement in the posterior mandible.- - - - - - - - - - ranking = 386.19863831423keywords = periapical (Clic here for more details about this article) |
5/10. Orthodontic treatment in a patient with Van der Woude's syndrome.Van der Woude's syndrome (VDW; #OMIM 119300) is an autosomal dominant disease characterized by cleft lip and/or palate and lower lip pit (fistula). The precise skeletal characteristics are unclear, and there have been no case reports of orthodontic treatment of patients with VDW. The Japanese girl whose treatment is reported here had VDW, including bilateral cleft lip and palate and bilateral symmetric lower lip pits. Orthodontic treatment started when she was just 3 years old, with a removable maxillary expansion appliance, followed by an edgewise multibracket appliance in both arches. Retention began at 11 years of age, and a secondary bone graft was performed for the alveolar cleft. She received prosthetic treatment and achieved a desirable occlusion at 18 years of age. Early intervention helped achieve a satisfactory treatment result for our patient. In contrast, her mother also had VDW, with a severe Class III skeletal pattern, but she had not been treated orthodontically; she had an anterior and lateral crossbite even after prosthetic treatment. The pretreatment characteristics of 4 other subjects with VDW are discussed; they show wide variations in the sizes of the maxilla and the mandible, suggesting that a common skeletal pattern is not generally seen in VDW.- - - - - - - - - - ranking = 0.074308156920812keywords = alveolar (Clic here for more details about this article) |
6/10. Periodontal lesions associated with deep traumatic overbite.Certain aspects of malocclusion, particularly deep overbite, can be related to periodontal pathology, especially in the presence of poor oral hygiene. The authors have noted an association between deep overbite and unusual periodontal lesions. These lesions often appear on radiographs as circumscribed radiolucencies, remote from the alveolar crest and sometimes close to the apex. Gingival surface injury and food impaction may be important aetiological factors. This is illustrated in this article by a number of case studies.- - - - - - - - - - ranking = 0.074308156920812keywords = alveolar (Clic here for more details about this article) |
7/10. The use of decellularized dermal grafting (AlloDerm) in persistent oro-nasal fistulas after tertiary cleft palate repair.To assess the efficacy of decellularized dermal grafting as an adjunct to the closure of recurrent oro-nasal fistulas. Five consecutive patients with recurrent oro-nasal fistulas were repaired with decellularized dermal grafting sandwiched between oral and nasal flaps of a von Langenbeck palatal repair. All patients had previously undergone a minimum of three prior palatal repairs with the recurrence of their oro-nasal fistula in the post-alveolar area. Decellularized dermal graft was placed between the nasal mucosa and the levator veli palatine muscle. patients were followed postoperatively and assessed for infection, dehiscence, signs of rejection, and fistula recurrence. All patients were followed for an average of three months. Clinical examination revealed no recurrence of their oro-nasal fistula nor associated symptoms of nasal reflux. Decellularized dermal grafts were not rejected nor extruded from the site of surgical repair. Decellularized dermal graft should be considered for use in the treatment of recurrent oro-nasal fistula after cleft palate repair. We would also like to encourage further clinical study.- - - - - - - - - - ranking = 0.074308156920812keywords = alveolar (Clic here for more details about this article) |
8/10. Two unusual cases of dental (periapical) infection.Cutaneous sinus tracts of dental origin are often a diagnostic challenge. A delay in correct diagnosis can result in inappropriate treatments. We describe two unusual cases of periapical infection. The first patient presented with a fistulized tumoral mass under the chin present for 1 year. The patient had only one tooth, and that was anatomically unrelated to the tumor. Radiological examination showed a dormant tooth that was infected periapically. The second case was a man who complained of asymmetry and change in his left nasolabial fold of 4-5 week's duration. On examination, the nasolabial folds were asymmetric without any sign of facial palsy. On intraoral examination, there was a severely decayed tooth on the same side. Radiological survey confirmed periapical infection. A few weeks after proper treatment, the nasolabial folds became symmetric.- - - - - - - - - - ranking = 901.13015606654keywords = periapical (Clic here for more details about this article) |
9/10. Clinical and histologic evaluation of an active "implant periapical lesion": a case report.A new entity called "implant periapical lesion" has recently been described. This lesion could be the result of, for example, bone overheating, implant overloading, presence of a preexisting infection or residual root fragments and foreign bodies in the bone, contamination of the implant, or implant placement in an infected maxillary sinus. This case report describes a titanium implant that was placed in the maxillary premolar region. A fenestration involving the middle portion of the implant was present. After 7 months, the apical portion of the implant showed radiolucency. This lesion rapidly increased in size and a vestibular fistula appeared. A systemic course of antibiotics was not successful, and the implant was then removed. The histologic examination showed the presence of necrotic bone inside the antirotational hole of the implant. The etiology of the implant failure in this instance could possibly be related to bone overheating associated with an excessive tightening of the implant and compression of the bone chips inside the apical hole, producing subsequent necrosis.- - - - - - - - - - ranking = 643.66439719039keywords = periapical (Clic here for more details about this article) |
10/10. An unusual presentation of a nasal septal abscess.Nasal septal abscess is a rare complication of septal haematoma. nasal obstruction and, less frequently, pain are the usual presenting features. We report a case of a nasal septal abscess in a 21-year-old female patient who developed a naso-oral fistula. To our knowledge this is the first report of such an unusual presentation of a septal abscess. The aetiology, pathogenesis and management of septal abscesses are discussed.- - - - - - - - - - ranking = 1.6keywords = abscess (Clic here for more details about this article) |
