Calcitonin: A non-invasive giant cells therapy

This paper reports four cases of central giant cell granuloma (CGCG) treated with calcitonin, attesting the efficacy and safety of its use as the chosen therapy for large CGCG. Four patients presenting CGCG treated with calcitonin were included in this study. Salmon calcitonin was administered for 6-28 months. It was observed determination of clear lesion limits for surgery, reduction and limitation of lesions. In aggressive cases, the calcitonin therapy was an excellent option, since it does not harm the patient, and a far less aggressive, complementary surgery may be performed in certain cases, avoiding life-long sequelae.

Self-drilling and Self-tapping Screws: An Ultrastructural Study

Objective:The aim of the current study was to compare self-drilling and self-tapping screws with regard to bone contact and the production of bone debris using scanning electron microscopy. Materials and Methods:Three New Zealand rabbit calvariae were used. Self-tapping and self-drilling screws were inserted into the outer surface of the skull with and without saline solution irrigation. All screws were 5 mm in length and were inserted until their tips projected through the endosteal side. Sixteen screws were used-8 with a head diameter of 1.5 mm and 8 with 2.0 mm. All self-tapping screws were inserted through a drill bit hole (1.6 mm for 2.0-mm screws and 1.3 mm for 1.5-mm screws). Results:There was no damage to the screws after insertion. Bone damage occurred when irrigation was not used during the installment of the self-tapping screws. Bone debris formed during the installment of the self-drilling screws, which is considered beneficial. Conclusions:Because the insertion of self-drilling screws is performed with manual pressure, irrigation is not essential. Unlike the drilling that occurs with self-tapping screw, the bone debris formed with self-drilling screws is not the result of the heat generated, but rather the result of biologically active bone tissue capable of reacting with the screw and improving its performance. The animal model used proved highly appropriate for comparisons with human beings because the bone structures of the head have the same density and thickness.

Mucosite e tratamento com laser - relato de dois casos

The following article aims to show the effects of low-level laser therapy in prophylaxis and treat- ment of patients with mucositis who are being treated with head and neck radiotherapy, through the report of two clinical cases. Key words: low-level laser thera- py, radiotherapy, mucositis.

Osteoma Dérmico – Relato de Caso

O osteoma e uma lesao osteogenica benigna que pode ser contituida por osso compacto ou esponjoso. A etiologia parece ser desconhecida, muito embora diversos autores tenham sugerido determinadas origens para justificar sua elucidacao, entre as quais: congenita, infecciosa e traumatica. Esta lesao apresenta crescimento lento, podendo ser encontrada, normalmente, na regiao crâniofacial, podendo ocorrer, raramente, em outros ossos. O diagnostico e feito acidentalmente, uma vez que esta lesao nao e acompanhada de alguma queixa de dor. O presente estudo se refere a ocorrencia desta patologia em regiao dermica, achado que nao foi relatado ate entao na literatura cientifica. Um homem com 31 anos de idade, procurou o Servico Bucomaxilofacial queixando-se de edema indolor na face. A combinacao entre os achados clinicos e radiograficos fundamentou o diagnostico de osteoma em regiao zigomatica.
