Use of Toothpaste and Toothbrushing Patterns Among Children and Adolescents - United States, 2013-2016.

MMWR Morb Mortal Wkly Rep 2019 Feb 1;68(4):87-90. Epub 2019 Feb 1.

Fluoride use is one of the main factors responsible for the decline in prevalence and severity of dental caries and cavities (tooth decay) in the United States (1). Brushing children's teeth is recommended when the first tooth erupts, as early as 6 months, and the first dental visit should occur no later than age 1 year (2-4). However, ingestion of too much fluoride while teeth are developing can result in visibly detectable changes in enamel structure such as discoloration and pitting (dental fluorosis) (1). Read More

There is no pulp necrosis or calcific metamorphosis of pulp induced by orthodontic treatment: biological basis.

Dental Press J Orthod 2018 Aug 1;23(4):36-42. Epub 2018 Aug 1.

Centro Universitário de Adamantina (Adamantina/SP, Brasil).

To biologically explain why the orthodontic treatment does not induce pulp necrosis and calcific metamorphosis of the pulp, this paper presents explanations based on pulp physiology, microscopy and pathology, and especially the cell and tissue phenomena that characterize the induced tooth movement. The final reflections are as follows: 1) the orthodontic movement does not induce pulp necrosis or calcific metamorphosis of the pulp; 2) there is no literature or experimental and clinical models to demonstrate or minimally evidence pulp alterations induced by orthodontic movement; 3) when pulp necrosis or calcific metamorphosis of the pulp is diagnosed during orthodontic treatment or soon after removal of orthodontic appliances, its etiology should be assigned to concussion dental trauma, rather than to orthodontic treatment; 4) the two pulp disorders that cause tooth discoloration in apparently healthy teeth are the aseptic pulp necrosis and calcific metamorphosis of the pulp, both only induced by dental trauma; 5) the concussion dental trauma still requires many clinical and laboratory studies with pertinent experimental models, to increasingly explain its effects on the periodontal and pulp tissues.

Statement Of Problem: Whether tooth whitening alters the surface topography of enamel causing an increase in surface roughness that could increase susceptibility to restaining is unclear.

Purpose: The purpose of this in vitro study was to evaluate whether immersing enamel in common solutions produces a color change of ΔE greater than 2; whether the highest concentration carbamide peroxide bleaching agent produces the greatest ΔE; whether bleaching increases the susceptibility to further staining by common solutions; and whether morphologic changes to the enamel surface are observed after staining and bleaching as evidenced by scanning electron microscopy (SEM) analysis and energy-dispersive X-ray spectroscopy (EDS).

Material And Methods: Forty-five extracted human teeth were immersed in 5 solutions (wine, coffee, tea, soda, and water) for 15 days at 80°C, and the change in ΔE was assessed with a colorimeter. Read More

Prospective Multicenter Clinical Cohort Study of a Novel Macro Hybrid Implant in Maxillary Anterior Postextraction Sockets: 1-Year Results.

Int J Periodontics Restorative Dent 2018 ;38(Suppl):s17-s27

A prospective cohort clinical study was performed to evaluate the concept and design of a novel macro hybrid implant placed into maxillary anterior postextraction sockets. Thirty-three patients with an equal number of hybrid implants were used to replace nonrestorable single anterior teeth with immediate tooth replacement therapy (immediate implant placement and immediate provisional restoration). The macro features of this hybrid implant are unique in geometry, as it combines two different shapes-a cylindrical coronal and tapered apical portion-into a singular body design, each comprising roughly half of the implant length.

Restoration of discolored endodontically treated anterior teeth: a minimally invasive chemomechanical approach.

Int J Esthet Dent 2018;13(3):302-317

In the case of discolored devitalized anterior teeth, several treatments are available to enhance the esthetic outcome, from noninvasive external/internal bleaching to freehand resin composites and more complex prosthetic solutions such as veneers or full crowns. Innovative computer-aided design/computer-aided manufacturing (CAD/CAM) chairside technologies and the introduction of new industrially polymerized composite resin blocks coupled with modern adhesive strategies have reduced both biological and financial costs compared to the classic post-core-crown approach. The aim of this article is to show how these new materials can be used in association with noninvasive internal and external tooth bleaching to restore a discolored, fractured, non-vital central incisor.
