Introduction: The study aimed to discuss the diagnosis and treatment of a six years old boy with severe pre-eruptive caries with preservation of pulp vitality after surgical exposure in the permanent mandibular molar. Pre-eruptive intra coronal caries are often an accidental lesion as a radiolucent finding in the coronal dentin of a tooth which did not erupted into the oral space (1). However, treatment modality is still not reported systematically (2). Case Presentation: The preventive approach effectively preserved the tooth vitality with no symptoms, while normal root development is processing during follow-up sessions. Conclusions: Accurate radiographic examination in visit and follow up sessions is fundamental for proper detection and intervention in pre-eruptive caries lesions.
Background: This study aimed to evaluate the cone-beam computed tomography (CBCT) technique considering its reliability to diagnose resorption due to maxillary impacted canine. Methods: In this cross-sectional study, 68 CBCT images were observed by two oral and maxillofacial radiologists. The position of the impacted maxillary canine was assessed, and the severity of root resorption in adjacent teeth was determined in two rounds by viewing. Finally, statistical analyses were performed according to the percentage of agreement, intra-class correlation coefficient, and kappa. The data sheets were filled out by two radiologists who observed the CBCT images in two separate weeks and recorded their opinions about the position of the crown and root of the impacted maxillary canine. Further, four adjacent teeth were examined for root resorption. Results: In most cases, no root resorption was observed in the lateral, central, and first premolars; however, the reported percentage of root resorption in the lateral premolar was higher than that of the others, and no root resorption was reported in the second premolars. Agreement on crown and root position was reported to be above 90% in all observations. In addition, the percentage of agreement was 98.5%, 95.6%, 98.5%, and 100% for root resorption, central incisor, lateral incisor, the first premolar, and the second premolar, respectively. Maxillary impacted canines were examined considering root resorption in adjacent teeth using CBCT, and its interpretation was reliable. Conclusions: Utilization of CBCT provides a worthy data about the impacted maxillary canine localization and effects on adjacent teeth, for more explanation and treatment of these cases.
: Intrusion is the most severe luxation injury, resulting in soft and hard tissue damage. Treatment depends on the root development stage and tooth intrusion degree. Lateral luxation describes tooth displacement in any direction other than axial. The prognosis of luxated teeth depends on the emergency treatment and elapsed time. This paper reports an 11-year-old boy who sustained displacement of central and lateral incisors into the nasal cavity, and his left canine had lateral luxation. Surgical repositioning was undertaken for intruded teeth, and a splint was placed. The canine could not be repositioned due to the delay, but its position improved toward the force of the cheek after several sessions. This study contains the data obtained from a one-year follow-up.
: This case report described a 10-year-old girl injured during a sports accident. Clinical examinations disclosed the extrusion, crown fracture, and subluxation of the anterior teeth of each jaw. At the same time, dental fragments were embedded within the lower lip soft tissue - the projected procedures concerned maintaining pulp vitality and periodontal stability of the fractured teeth with an 18-month follow-up.
A non-common case of unilateral fusion between the left upper central tooth and the supernumerary deciduous tooth, which also has an extra maxillary impacted tooth, was reported in the present study. The patient was a 9-year-old Iranian boy. The left lateral maxillary tooth was found during the oral examination. In the radiographic presentations, the fused teeth showed separate roots, pulpal chambers, and separate root canals. Delayed eruption of the first and second maxillary permanent incisors was experienced due to the presence of an extra impacted tooth. In the management of this condition, both the deciduous fused teeth and extra impacted teeth were removed, and an appointment was scheduled for three months to check for spontaneous tooth eruption.
