Apresenta, após o tumor misto, a maior ocorrência entre todos os tumores de glândula salivar. O CM é composto por uma variedade de tipos celulares. A aparência inócua do neoplasma dificulta o diagnóstico diferencial com outras lesões benignas, como o cisto de retenção salivar, hemangioma, nevos ou processos císticos. Este artigo relata um caso de CM em paciente jovem, masculino, com 20 anos, submetido a tratamento cirúrgico, seguido de braquiterapia.

Afeta fundamentalmente os sistemas esquelético, cardiovascular e ocular. Sua etiologia está relacionada a mutações no gene da fibrilina-1 (FBN1),* localizado no cromossomo 15 (15q21.1). As alterações dento-faciais presentes na síndrome, além de outras características relacionadas ao sistema estomatognático, tornam importantes o reconhecimento desta condição e o adequado manejo do paciente pelo profissional da Odontologia. O objetivo deste artigo é revisar a literatura que relaciona a SM à Odontologia.

Nasal characteristics of these patients, as well as the effects of these procedures upon nasal patency, have not been well described yet. In the present study, measurements performed by acoustic rhinometry and frontal cephalometry in 13 patients presenting maxillary deficiencies, before and after surgically assisted maxillary expansion (SARME), were compared with those of 10 individuals with normal dentofacial characteristics and without nasal symptoms. The variables analysed were minor cross-sectional area (MCA) and nasal volume, maxillomandibular transverse index and nasal and maxillary width. The results showed a smaller transverse width and MCA in the patients as compared with normal controls. All measurements showed a tendency to increase after SARME. The nasal volumes did not differ. The nasal width showed wide variation. There was no correlation among the variables. Patients presenting maxillary transverse deficiency seem to have lower values for nasal MCA, with a tendency to increase after SARME.

This study evaluated the effects of LLLT on peri-implant healing in vivo. Thirty-two rabbits had their mandibular left incisors removed, followed by immediate insertion of a dental implant into the fresh socket. Animals were assigned randomly to four groups: control (non-irradiated) or LLLT at three different doses per session: 5J/cm(2), 10J/cm(2), and 20J/cm(2). A GaAlAs laser (830nm, 50mW) was applied every 48h for 13 days, starting immediately after surgery. The implant stability quotient (ISQ) was measured using resonance frequency analysis upon implant insertion and immediately after death, 30 days after the last application. Tissues were prepared for scanning electron microscopy (SEM) and stereology. Variables measured were bone-implant contact (BIC) and bone neoformation within implant threads at three different sites. The results showed better ISQ for the 20J/cm(2) group (P=0.0...

LLLT has been shown to accelerate tissue repair and osseointegration of implants placed into the rabbit tibia. However, the beneficial effects of LLLT have never been tested in the rabbit mandible, which would more closely mimic the human situation. Twenty-four male New Zealand rabbits were randomly divided into four groups of six animals each. All animals had their left mandibular incisors extracted, followed by immediate insertion of a titanium dental implant in the fresh socket. Three groups received LLLT [aluminum-gallium-arsenide (AlGaAs), λ=830nm, 50 mW, continuous wave (CW)] at three different energy densities per treatment session (E-5, 5 J/cm(2); E-10, 10 J/cm(2); and E-20, 20 J/cm(2)). Irradiation was performed every 48 h for 13 days, totaling seven sessions. One group received sham treatment (controls). Histological sec...
