    In a cross-sectional study, 150 parents or guardians of children and adolescents provided sociodemographic data and answered questions about their interest in receiving oral health education through digital technologies. Most participants expressed interest in receiving information and thought that messages about oral health could improve their daily care at home.

    Tooth fragment reattachment was performed for a total of 5 fractured teeth in 4 children aged 8 to 11 years. After a follow-up of 9 months to 4 years, the perceived clinical changes were minor. Four teeth were vital, and 1 tooth had a periapical lesion requiring endodontic treatment. Results of the Oral Health Impact Profile-Aesthetic questionnaire revealed an improvement in the oral health–related quality of life.

    This case report describes the treatment of a 75-year-old woman who presented with severe oral lichenoid hypersensitivity reactions secondary to an undiagnosed underlying thymoma. No substantial improvement of the oral conditions was achieved with conventional therapies; however, almost complete resolution of the lesions was achieved following completion of radiation therapy for the thymic mass.

  • Oral Medicine, Oral Diagnosis, Oral Pathology Giant sialolith associated with Actinomyces infection, suggesting a new etiopathogenic correlation: a case report

    This article reexamines the etiopathogenesis of sialolithiasis based on the interpretation of data reported in the literature and the interpretation of scanning electron microscopic, histopathologic, fluorescence, and energy-dispersive X-ray spectroscopic studies of a giant sialolith from a single patient. The authors propose that the triple synergism of microbiota, biofilm, and salivary dynamics plays a fundamental role in the development and intrinsic architecture of sialoliths.

    Peter C. Moon

    The objective of this study was to evaluate the effects of different surface treatments on the microshear bond strength of resin cements to zirconia. Three different resin luting agents were bonded to zirconia blocks pretreated with alumina abrasion (control), tribochemical silicoating, or 1 of 2 adhesive primers. The results suggest that the effects of different surface treatments may be specific for each cement.

  • Oral Medicine, Oral Diagnosis, Oral Pathology Frequency and types of incidental findings on limited field of view CBCT scans

    A retrospective study identified and categorized incidental findings on 474 limited field of view (LFOV) cone beam computed tomographic (CBCT) scans. At least 1 incidental finding was detected on 51.5% of scans, and 70.5% of the findings were recommended for referral or additional treatment, indicating that the use of a CBCT system with an LFOV does not diminish the need to conduct a thorough evaluation of the images.

    This case report describes the use of an erbium, chromium-doped: yttrium-scandium-gallium-garnet (Er,Cr:YSGG) laser to remove a 3-unit fixed partial denture that required pontic repair. The successful procedure shows that atraumatic debonding of a high-strength ceramic can be predictably performed with the Er,Cr:YSGG laser when appropriate settings are used.

    This case report describes the use of a laser to treat hypersensitive teeth affected by molar-incisor hypomineralization. After photobiomodulation therapy, fluoride applications, and placement of restorations, the 11-year-old patient reported a reduction in hypersensitivity and an improved quality of life.

    The objective of this article is to report a case of congenital epulis in a newborn. During an intraoral examination of a 10-day old neonate, an exophytic lesion was found in the maxillary left alveolar ridge. The patient underwent an excisional biopsy with a 2% lidocaine local anesthetic, and histopathologic examination of the biopsy specimen confirmed the diagnosis.

    An in vitro study assessed the thermal effect of irradiation on the setting time of mineral trioxide aggregate (MTA) and calcium-enriched mixture (CEM) cements. The MTA specimens were light cured for 20, 40, or 60 seconds, while the CEM specimens were cured for 60, 90, or 120 seconds. Control specimens of each material underwent no irradiation, but all experimental and control groups had 60 seconds of rest time. The findings showed that light curing can significantly decrease the setting time for MTA and CEM cements.

    Guilherme de Siqueira Ferreira Anzaloni Saavedra

    This article describes a procedure for restoring teeth with a custom 1-piece glass fiber–reinforced post and core fabricated using computer-aided design/computer-aided manufacturing. Because of better adaptation, this endodontic post enables use of a thinner and homogenous cement layer; in addition, it eliminates the need to construct a composite resin core build-up.

    Paracoccidioidomycosis is an infectious disease caused by the fungus Paracoccidioides brasiliensis and is endemic in South America. Oral manifestations are often the first clinical sign of infection, but their appearance can vary. This article reports 2 cases of paracoccidioidomycosis and emphasizes the importance of performing detailed clinical examinations to ensure accurate diagnoses.
