Accidental aspiration of foreign bodies in dental practice: clinical management and prevention
No full textObjectiveForeign body aspiration is a possible complication of dental treatment that may result in a life-threatening situation. The foreign body is often spontaneously ejected from the airway, but in other cases, surgical intervention is needed. Prevention, diagnostic procedures, treatment and complications are discussed.
Materials and methodsThree cases of aspiration of dental instruments are described: the piece was localised in the right main bronchus in two cases and in the left main bronchus in one case.
ResultsAll three cases underwent surgery (resection and bronchoscopy); in one case, the surgical attempt failed, and the foreign body was not located by radiography; it was assumed to have been expelled spontaneously.
ConclusionThe management of dental materials and instruments requires particular care, especially if the patient is supine or semi-recumbent. The dentist must be able to manage emergency situations in which patients accidentally inspire or swallow dental instruments or materials during treatment. Preventive techniques must be put in place because these incidents are preventable if the correct precautions are taken
Space-maintaining management in maxillary sinus lifting: a novel technique using a resorbable polymeric thermo-reversible gel
No full textSeveral techniques have been proposed to achieve sinus floor elevation and the formation of new bone through the grafting of autologous, heterologous, or alloplastic materials. The grafted materials act as a scaffold for bone formation inside the maxillary sinus. This study investigated a non-graft sinus lifting procedure using a resorbable polymeric thermo-reversible gel. A space-maintaining approach to sinus lifting, using a resorbable polymeric thermo-reversible gel, was applied in 11 patients undergoing implant treatment in the atrophic posterior maxilla. After a healing period of 6 months, a total of 14 implants were placed; biopsies were taken and evaluated histologically and histomorphometrically. The parameters evaluated included the percentages of new bone formation, residual gel, and fibrous tissue. Histological examination showed the formation of new bone with no fibrous tissue or severe inflammatory cellular infiltration. The percentage of newly formed bone was in the range of 54–60%; this consisted of both lamellar and woven bone. No foreign-body reaction was observed. The mean quantities of both residual gel and connective tissue were small. This non-graft sinus lifting procedure using a space-maintaining gel appears to stimulate predictable bone formation; it is thus a useful technique for promoting bone formation in the sinus
Osteoblastoma of the jaw: Report of two cases and review of the literature
No full textOsteoblastoma is a benign bone tumor of osteoblastic origin. Two cases, an 8-year-old boy and a 24-year-old man, are presented. Both tumors were resected with wide surgical margins and neither patient had adjuvant radiation or chemotherapy. The patients showed no evidence of local recurrence after six to seven years. The clinical, radiological, histological and immunohistochemical features are described. Differential diagnosis and immunohistochemical features potentially useful for refining diagnosis of osteoblastoma are also discussed

No full textOBJECTIVE:
This study aimed to evaluate the efficacy of diode laser for the surgical treatment of neurofibromas (NF), in terms of clinical outcome and therapeutic success.
BACKGROUND DATA:
The NF is a benign tumor of the peripheral nerve sheath, characterized by the proliferation of Schwann cells, perineural cells, and endoneural fibroblasts. NF may occur as a solitary lesion, or as part of a generalized neurofibromatosis syndrome; much more rarely it occurs in the form of multiple neurofibromas with no associated syndrome. Two distinct variants of neurofibromatosis have been described: types I and II.
METHODS:
Ten cases are reported (6 women and 4 men, age range 43-70 years) with smooth, painful, or painless lesions of the oral mucosa. Lesions were completely excised using a diode laser at 980 nm wavelength, average power 2.0 W, in continuous wave mode, with 320 μm optical fibers, for 45 sec average time.
RESULTS:
Complete healing occurred within 20 days. There were no adverse effects; patients were carefully followed up and there have been no recurrences after an interval of 3 months to 3 years.
CONCLUSIONS:
The results of this diode laser treatment of NF demonstrate good effectiveness of this novel therapy, which may replace conventional surgical procedures
