Angina bullosa hemorrhagica is characterized by blood blisters in the oral or oropharyngeal mucosa. This case series reports 7 cases of angina bullosa hemorrhagica, reviews 199 cases reported in the English literature, and discusses possible etiologic factors, predisposing factors, and differential diagnoses.

Evaluation of permanent maxillary canines through visual examination, periapical radiography, and cone beam computed tomography (CBCT) revealed that, generally, only 1 root canal was present, the root showed apical curvature to the distal side, and the foramen was located in the center of the radicular apex. Both CBCT and periapical radiography allowed reliable measurement of the canine length and root width.

A diminutive fibrotic overgrowth was located on the labial interproximal gingiva between the canine and first premolar in a 68-year-old woman. Surgical excision and histologic examination led to a diagnosis of gingival cyst of the adult, which is a relatively rare, benign odontogenic cyst.

This study compared the repair bond strengths of a methacrylate composite (MC) and a silorane composite (SC) for repairs made at 5 different times after the original polymerization. The repair bond strength of the SC was significantly less than its original cohesive strength at every repair time, but the repair bond strength of the MC was only reduced when the repair was made at 1 week.

This article presents a customized protocol for timing of soft tissue management around dental implants. The width and thickness of keratinized tissue, the need for bone management, and local risk factors influencing esthetics determine the appropriate time for soft tissue augmentation procedures.

When a 26-year-old man presented with an asymptomatic submucosal fibroelastic nodule covered by normal-appearing mucosa in the hard palate, the working diagnosis was minor salivary gland tumor, but histologic analysis of the biopsy specimen revealed the characteristic cellular patterns of a schwannoma. Clinicians should consider schwannoma in the differential diagnosis for palatal nodules and manage them with incisional biopsy and prompt treatment.

A 9-year-old boy with an unerupted permanent maxillary right central incisor had suffered trauma to the primary predecessor at the age of 2 years. When radiographs revealed impaction and root dilaceration, the permanent tooth was extracted and found to present several abnormalities: enamel hypoplasia, enamel discoloration, root dilaceration, and root duplication.

An in vitro study evaluated enamel microhardness following bleaching with either high- or low-concentration hydrogen peroxide agents containing calcium and/or fluoride. Microhardness values were significantly influenced by the bleaching agent and application time. Enamel microhardness values decreased over time, regardless of the agent used or the addition of calcium and/or fluoride.

Significant craniofacial changes may occur in adults as a result of continuous dental eruption, vertical soft tissue augmentation, or facial bone growth. Twelve-year follow-up of a dental implant, placed in a maxillary central incisor site when the patient was 20 years old, revealed a relative positional change that negatively impacted esthetics.

This clinical case report describes the successful use of a reciprocating single-file system for the endodontic treatment of a mandibular molar with internal root resorption. No painful symptoms or periapical lesions were observed at a 12-month follow-up.

A periapical lesion associated with bone rarefaction at a maxillary canine was
not identified on the periapical radiograph but was evident on a cone beam
computed tomogram (CBCT), confirming the usefulness of this tool for diagnosis
of periapical lesions.

Intrusive luxation, characterized by axial displacement of the tooth into the alveolar bone, is rare in the permanent dentition. This case report describes the long-term follow-up of an immature permanent maxillary central incisor that was allowed to reerupt after intrusive luxation.
