Central and peripheral nervous complications of dental treatment

Abstract

SUUMARY -This review outlines the complications involving the central or peripheral nervous system arising from dental procedures reported in the last decade. By far the commonest complications were related to intraoperative mechanical peripheral nerve injury. Trauma to branches of the mandibular nerve occuring during oral operations may potentially result in varying degrees of hypoesthesia, paresthesia, dysesthesia or in chronic pain syndromes. An increase in malpractice suits related to such a complication has been recognized in the late years. A warning of the possibility of occurrence of this complication should to be given to all patients undergoing sinus thrombophlebitis) and anesthesiological complications (occular and facial palsies, optic nerve injury and complications related to general anesthesia) were also reported in this period.KEY WORDS: anesthesia, dental, adverse effects; dental, complications; dentistry, operative; inferior alveolar nerve, injury; lingual nerve, injury; nerve block, adverse effects; sensation disorders, etiology; third molar; tooth extraction, adverse effects. Complicações de tratamento dentário afetando o sistema nervosoRESUMO -Complicações, ou eventos inesperados e indesejáveis associados a terapia de uma dada condição, podem ser particularmente incapacitantes quando afetam o sistema nervoso. A proximidade de cavidade craniana e a rica inervação dos tecidos orais representam risco potencialmente alto de disseminação de infecções para o sistema nervoso central e de lesões de troncos nervosos em procedimentos dentários. Em vista do aumento da ocorrência de processos para compensação financeira após tais complicações, é provável que parcela considerável

Bacterial meningitis after tooth extraction

“…Descriptions of systemic infections include endocarditis, mediastinitis, orbital abscess, abscess of the brain, or septic venous sinus thrombosis. [5][6][7][8] The most frequent agents are Streptococcus viridans (55%), Staphylococcus aureus (30%), Enterococcus (6%). 9 Meningitides after tooth extraction or oral surgery have also been described.…”

“…9 Meningitides after tooth extraction or oral surgery have also been described. 5,10,11 Since, depending on the agent, bacterial meningitides are still associated with a mortality rate of 10 to 15 % (WHO 2000), they remain a seriously threatening disease. Hence, it is important for general dentists to recognise this clinical picture in order to be able to initiate the necessary treatment.…”

Eficácia da articaína, da bupivacaína e da lidocaína associadas à epinefrina em pacientes com pulpite irreversível em molares mandibulares

“…Estas incluem: injeção de ligamento periodontal (PDL), injeção intrapulpar, injeção intra-óssea (IO) e injeção intrasseptal (Parente et al, 1998). Injeções complementares são essenciais em pacientes com pulpite irreversível, uma vez que possuem uma taxa de falha oito vezes maior quando comparadas com pacientes normais (Verma et al, 2013) e injeções intrapulpares podem ser eficientes por meio da anestesia por pressão (Bhuyan et al, 2014 (Rossitti, 1995;Vongsavan;Matthews, 2007).…”
