Impaction of permanent upper canine causedby supernumerary tooth with talon cusp type III

Introduction: The talon cusp is defined as a developmental anomaly in which an accessory cusp-like structure projects in the area of the cingulum or cementoenamel junction in the anterior teeth attached to the lingual surface of the crown, ranging in size, shape, length and degree of union with the surface. Case report: This study aimed to report a case of a patient who came to Clinic for Preventive Dentistry of Federal University of Pernambuco, Recife-PE, Brazil, complaining of pain in the upper left region. The clinical exam observed the presence of a supernumerary tooth with talon cusp type III in the canine region which had a carious lesion in the developmental groove at the mesial surface and caused a prolonged retention of permanent tooth. Conclusion: With this we want to emphasize that the Dental Surgeon be aware of the changes caused by dental morphological variations, seeking to conduct a proper treatment plan, meeting the functional and aesthetic needs of the patient.

Dexmedetomidine for awake craniotomy without laryngeal mask

OBJECTIVE: This paper reports the use of dexmedetomidine in three epileptic patients with cavernous angiomas that underwent awake surgery in order to map their speech areas. METHOD: Loading dose of dexmedetomidine varied from 1 microg/Kg/h to 3 microg/Kg/h over 20 minutes and maintenance dose from 0.4 microg/Kg/h to 0.8 microg/Kg/h. RESULTS: There was no occurrence of hemodynamic instability, convulsions or respiratory depression. Patients tolerated well the procedure. CONCLUSION: Dexmedetomidine was useful for awake craniotomy as it decreased patients level of consciousness but did not produce agitation. Laryngeal mask was not necessary to keep air ventilation.

OBJETIVO: Este trabalho relata o uso de desmedetomidina em três pacientes com angiomas cavernosos próximos a área de linguagem e epilepsia que foram operados acordados para mapeamento cortical. MÉTODO: A dose de ataque de dexmedetomidina variou de 1 mg/Kg/h a 3 mg/Kg/h durante 20 minutos e dose de manutenção de 0,4 mg/Kg/h a 0,8 mg/Kg/h. RESULTADOS: Os pacientes toleraram bem o procedimento e não houve instabilidade hemodinâmica, convulsões ou depressão respiratória. CONCLUSÃO: Dexmedetomidina foi útil nas craniotomias com o paciente acordado para mapeamento cortical pois gerou sedação sem agitação. A máscara laríngea não foi necessária para manter a ventilação nesses pacientes.
