RESUMO
This study investigated the extent of complete anaesthesia from buccal nerve block. 40 healthy Thai patients (20 males; 20 females) requiring buccal nerve block for surgery were studied. After the buccal nerve was blocked, the buccal mucosa was explored using a sharp probe to map out the extent of anaesthesia. The operation was carried out after inferior alveolar and lingual nerve block. The extent of the anaesthesia was mainly from the retromolar area to the second molar, followed by the first molar to the second premolar, whilst the first premolar to the central incisor was the area least affected. An important finding of this study was that the anaesthetized extent of some patients extended to the anterior region on the same quadrant. This study showed the affected areas of buccal nerve anaesthesia extended through the buccal mucosa from the first premolar to the central incisor in some patients. It can serve as another informative indication for lower anterior surgery.

Dentinal dysplasia is one of the rarest hereditary disturbances of dentin formation characterized by the teeth present with short blunt roots, considerably reduced or obliterated pulp spaces, periapical abscess or cysts without an obvious causative factor, and spontaneous exfoliated. These features were observed on a patient referred for prosthodontic assessment, and an investigation of other members of the family revealed that the father and two siblings were also affected. The report described the clinical, radiographic, histologic and scanning electron microscopic features and discussed the features which separated from dentinogenesis imperfecta.
