Occurrences of rare oral complications following herpes zoster (HZ) infection have been reported. In the present case, a 57-year-old man was referred for periodontal evaluation due to gingival bleeding. His medical history included diagnoses of chronic lymphocytic leukemia and HZ infection. Intraoral examination revealed necrosis and alveolar bone exposure around the mandibular left lateral incisor, and the patient reported spontaneous exfoliation of the maxillary and mandibular left central incisors. Conservative surgical and antibiotic therapies were provided to the patient, and a diagnosis of osteonecrosis of the jaw following HZ infection was established. There were no signs of recurrence in 17 months of follow-up. Clinicians should be aware of unusual complications related to a previous HZ infection.The aim of this study was to evaluate the influence of surface sealant and erosive challenge on the color change of composite resin after artificial staining with coffee. Forty-eight composite specimens (8 × 1 mm) were prepared and divided into 4 groups (n = 12) based on the timing of sealant application (immediate vs delayed) and exposure to acid (erosive challenge vs no challenge). The groups were subjected to the procedures in the following order 1, sealant application, erosive challenge, color measurement, coffee immersion, and color measurement; 2, sealant application, color measurement, coffee immersion, and color measurement; 3, erosive challenge, color measurement, sealant application, coffee immersion, and color measurement; and 4, color measurement, sealant application, coffee immersion, and color measurement. In groups 1 and 2, surface sealant was applied immediately after preparation of the specimens. In groups 3 and 4, sealant was applied after the first color measurement. Color was measured with a spectrophotometer using the CIE L*a*b* system. The erosive challenge (groups 1 and 3) was carried out in 0.01M hydrochloric acid, 150 mL/cycle, at room temperature (2-minute immersions 4 times a day for 5 days). After all specimens were immersed in coffee for 14 days, new color measurements were performed. For total color change (∆E*), groups 1 (21.01) and 2 (23.10) presented lower values than groups 3 (27.76) and 4 (26.57). For luminosity (∆L*), the opposite occurred (groups 1, -16.84; 2, -17.72; 3, -22.62; and 4, -21.22). For ∆a* and ∆b*, the only statistically significant difference was the group 1 ∆b* value, which was the lowest among all groups. The opacity remained stable in all groups. The results suggest that resin luminosity decreases and color variation increases when surface sealant is applied after erosive cycling and storage.The oral mucosa has superior wound healing potential compared to other mucosal tissues. The objective of this article is to review the current state of evidence on the mechanisms that govern accelerated oral mucosal wound healing and explore clinical approaches that facilitate the natural course of these processes.Panoramic radiography is a useful screening tool for an array of dental and nonodontogenic disorders related to calcification as well as assessment of trauma and development of the oral and maxillofacial complex. Rotational movements of the radiographic source and detector plate may promote ghost image formation, particularly with larger radiopaque objects, and complicate the radiographic interpretation. Cp2-SO4 cost This article describes cases of a giant submandibular gland sialolith and a giant tonsillolith, each of which appeared as a bilateral presentation due to contralateral ghost images, and discusses their clinical, demographic, and radiographic characteristics. Computed tomographic examinations were used to confirm the unilateral presentation of these objects and for determination of the extent of adjacent soft tissue impingement. Distinguishing an actual panoramic image from a ghost artifact may avoid unnecessary surgical intervention and improve clinical outcomes.Implant-supported overdentures are becoming a common treatment modality, providing functional and esthetic results for patients in need of full-mouth rehabilitation. Because anatomical variations in the residual ridge affect treatment planning, the aim of this retrospective study was to present quantitative descriptions of the interforaminal region by evaluating a large series of cone beam computed tomographic (CBCT) images of the mandibles of edentulous patients in need of anterior dental implants. The sample included a total of 180 CBCT scans (360 sites) of patients requiring endosseous implant placement in the anterior region of the mandible for implant-assisted overdentures. The CBCT images were evaluated for parameters such as ridge height, width, angulation, and undercuts; crestal height; and corticocancellous bone ratios. The statistical analyses included the independent-samples t test and chi-square analysis. The mean (SD) ridge height was 18.16 (0.36) mm on the right side and 17.79 (0.38) mm on the lvely, but the differentiation between the right and left sides was clinically insignificant. Knowledge of the patient's anatomical variations will allow the clinician to formulate an individualized treatment plan.Hyperpneumatization of the temporal bone (HPTB) is a rare finding, and its clinical impact is poorly described in literature. We report the case of a 34-year-old woman with no previous otologic condition, complaining of paroxysmal vertigo and right pulsatile tinnitus shortly after a first scuba diving session. Clinical neurotologic assessment found a right vestibular impairment. Cranial tomodensitometry showed a bilateral hyperpneumatization of the petrosal air cell system. Brain magnetic resonance imaging to rule out any retrocochlear pathology was normal, although the cochleo-vestibular nerve (CVN) appeared to be over lengthened in a narrowed internal auditory canal (IAC), especially on the right-hand side. Pain was alleviated by administration of a low-dose anti-epileptic drug. The clinical, neurological, and radiological findings evoked a right vestibulopathy generated by a limited compression of the CVN; HPTB appeared to contribute to the narrowing of the IAC, especially on the right-hand side.
