Hairy Tongue: Differential Diagnosis by Use of Widefield Optical Fluorescence.

Braz Dent J 2019 Mar-Apr;30(2):191-196. Epub 2019 Apr 4.

Núcleo de Pesquisa em Química Biológica (NQBio), UFSJ - Universidade Federal de São João Del Rei, Divinópolis, MG, Brasil.

Hairy tongue is a benign pathology, characterized clinically by hyperkeratinized plaques on the dorsal surface of the tongue, hairlike, whose coloration ranges from unpigment, whitish, yellowish, green, brown to black. Diagnosis is clinical, and, in cases of whitish plaques, it may be difficult to differentiate between oral hairy leukoplakia, potentially malignant leukoplakia or squamous cell carcinoma. Thus, widefield optical fluorescence complementary examination may allow a better visualization of the local hairlike pattern of hyperkeratinization, typical of the hairy tongue, facilitating the diagnosis.

In Vivo Study of the Action of a Topical Anti-Inflammatory Drug In Rat Teeth Submitted To Dental Bleaching.

Braz Dent J 2018 Nov-Dec;29(6):555-561

Endodontics, Araçatuba Dental School, UNESP - Universidade Estadual Paulista, Araçatuba, SP, Brazil.

Bleaching gel containing hydrogen peroxide (H2O2) cause damages in pulp tissue. This study investigated the action of a topical anti-inflammatory, the Otosporin®, in rats' bleached teeth with the null hypothesis of which the Otosporin® is no able to minimize the pulp inflammation that bleaching gel generates. The rat's molars were divided into groups: BLE: bleached (35% H2O2 concentration /single application of 30 min); BLE-O: bleached followed by Otosporin® (10 min); and control: placebo gel. Read More

Effect of Aging on Dentinal Crack Formation after Treatment and Retreatment Procedures: a Micro-CT Study.

Braz Dent J 2018 Nov-Dec;29(6):530-535

Department of Endodontics and Geriatric Dentistry, UFF - Universidade Federal Fluminsense Niteroi, RJ, Brazil.

In order to evaluate the volume of dentinal cracks taking into account the age of the dentin and the type of file system used for endodontic procedures, forty freshly extracted single-rooted lower incisive teeth presenting similar root volume, were divided into two groups according to the age of the patient: Group Young (18 - 30 years old) and Group Old (60 years old or more). Each specimen was scanned by microcomputed tomography (micro-CT) in three stages: (i) before any treatment, (ii) after endodontic treatment with Reciproc files (REC), and (iii) after subsequent endodontic retreatment. Each group was subdivided into two subgroups, according to the retreatment technique used: retreatment with REC or with ProTaper Universal Retreatment (PUR) files. Read More

Development of a New Cone-Beam Computed Tomography Software for Endodontic Diagnosis.

Braz Dent J 2018 Nov-Dec;29(6):517-529

Department of Endodontics, University of Texas Health at ,TX, USA.

Cone-beam computed tomography (CBCT) has promoted changes in approaches in Endodontics, and enhanced decision-making in complex clinical cases. Despite the technological advancements in CBCT hardware, the interpretation of the acquired images is still compromised by viewing software packages that often have limited navigational tools and lack adequate filters to overcome some challenges of the CBCT technology such as artefacts. This study reviews the current limitations of CBCT and the potential of a new CBCT software package (e-Vol DX, CDT- Brazil) to overcome these aspects and support diagnosing, planning and managing of endodontic cases.

Braz Dent J 2018 Sep-Oct;29(5):435-445

Universidade Positivo, Curitiba, PR, Brazil.

This study aimed to evaluate the effect of two methods of local application of alendronate and parathyroid hormone (PTH) on bone repair and the systemic implications.
