Aim: To compare 24-month pulp health outcomes of partial caries removal (PCR) and total caries removal (TCR) with composite restoration in primary molars. Methods: 48 children aged 3-8 years with at least one molar with a deep carious lesion were included. 120 teeth were randomized to control (TCR; n = 54; 69% class II) and test (PCR; n = 66; 63% class II) groups. Total absence of carious tissue was confirmed using a blunt-tipped probe in the TCR group. For PCR, excavation was stopped when hardened, dried dentin with a leathery consistency was achieved. Pulpotomy was performed in cases of pulp exposure. Results: Pulp exposure occurred in 2 and 27.5% of teeth treated with PCR and TCR, respectively (p < 0.01). The operative time was significantly higher for TCR than PCR. Success rates were 92 and 96% in the PCR and TCR groups, respectively (p = 0.34). The success rate tended to be lower in occlusoproximal (92%) than in occlusal (100%) lesions (p = 0.08). Conclusion: The clinical and radiographic success rates of PCR and TCR in primary teeth with deep carious lesions were high and did not differ significantly, indicating that PCR is a reliable minimally invasive approach in primary teeth and that the retention of carious dentin does not interfere with pulp vitality. Moreover, PCR provided other clinically relevant advantages over TCR, especially lower incidence of pulp exposure and lower operative time.
-Recurrent episodes of abdominal pain are common in childhood. Among the diagnostic possibilities are migraine and abdominal epilepsy (AE). AE is an infrequent syndrome with paroxystic episodes of abdominal pain, awareness disturbance, EEG abnormalities and positive results with the introduction of antiepileptic drugs. We present one 6 year-old girl who had short episodes of abdominal pain since the age of 4. The pain was followed by cry, fear and occasionally secondary generalization. MRI showed tumor in the left temporal region. As a differential diagnosis, we report a 10 year-old boy who had long episodes of abdominal pain accompanied by blurring of vision, vertigo, gait ataxia, dysarthria, acroparesthesias and vomiting. He received the diagnosis of basilar migraine. In our opinion, AE is part of a large group (partial epilepsies) and does not require a special classification. Pediatric neurologists must be aware of these two entities that may cause abdominal pain. RESUMO -Episódios recorrentes de dor abdominal são freqüentes na infância e entre as causas neurológicas há migrânea e epilepsia abdominal (EA). EA é uma síndrome que consiste de episódios paroxísticos de dor abdominal associada à alteração de consciência, anormalidades eletrencefalográficas e boa resposta à terapia anticonvulsivante. Apresentamos uma menina de 6 anos que tinha desde os 4 anos episódios de curta duração de dor abdominal, seguidos por choro, medo e ocasional generalização secundária. A RM mostrou a presença de um tumor em região temporal esquerda. Como diagnóstico diferencial, apresentamos um menino de 10 anos que há 12 meses referia episódios de dor abdominal de longa duração acompanhados por turvação visual, vertigem, marcha atáxica, disartria, acroparestesia e vômito, recebendo posteriormente o diagnóstico de migrânia basilar. Em nossa opinião, EA faz parte de um grande grupo (epilepsias parciais) e não requer uma classificação especial. O neuropediatra deve estar alerta para essas duas entidades que podem cursar com dor abdominal. PALAVRAS-CHAVE: crises parciais, tumor do lobo temporal, migrânea basilar, dor abdominal e epilepsia sintomática.
