Hyeon-Jong Yang

Korean J Pediatr 2019 Mar 15. Epub 2019 Mar 15.

Pediatric Allergy and Respiratory Center, Department of Pediatrics, Soonchunhyang University Seoul Hospital, Soonchunhyang University College of Medicine, Seoul, Korea.

Mycoplasma pneumoniae pneumonia (MPP) has been generally susceptible to macrolides, however emergence of macrolide-resistant Mycoplasma pneumoniae pneumonia (MRMP) has made the treatment of MPP challenging. MRMP rapidly spread after 2000s, especially in the Eastern Asia. MRMPs are more common in children and adolescents than in adults, which is likely related to the frequent use of macrolides for treatments of MP infections in children. Read More

Wear and damage at the bonded interface between tooth enamel and resin composite.

J Dent 2019 Apr 20;83:40-49. Epub 2019 Feb 20.

State Key Laboratory of Oral Diseases, National Clinical Research Center for Oral Diseases, West China Hospital of Stomatology, Sichuan University, Chengdu, China. Electronic address:

Objective: To investigate the wear mechanisms and evolution of damage in tooth enamel-resin composite bonded interfaces caused by sliding contact, and to develop an understanding of interface degradation from a tribological viewpoint that supports clinical recommendations for improving interface integrity.

Methods: Reciprocating wear tests were performed on bonded interface samples involving commercial resin composite (Tetric N Ceram Bulk Fill), resin cement (Rely X U200) and tooth enamel using the ball-on-flat configuration. The bonded samples were subjected up to 5 × 10 cycles of sliding contact, and the wear depth and wear track morphology were characterized after increments using white light interferometry and scanning electron microscopy, respectively.

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

Braz Dent J 2018 Sep-Oct;29(5):409-418

Department of Dentistry, UFSC - Universidade Federal de Santa Catarina, Florianópolis, SC, Brazil.

This systematic review aimed to evaluate whether alternative materials to conventional triple antibiotic paste (TAP - metronidazole, ciprofloxacin, and minocycline) and grey mineral trioxide aggregate (GMTA) could avoid tooth discoloration in teeth submitted to Regenerative Endodontic Procedure (REP). It was also investigated if dental bleaching is able to reverse the color of darkened teeth due to REP. The search was conducted in four databases (Medline via PubMed, Scopus, ISI Web of Science and BVS - Virtual health library), following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses.

How safe is doxycycline for young children or for pregnant or breastfeeding women?

Diagn Microbiol Infect Dis 2019 Mar 4;93(3):238-242. Epub 2018 Oct 4.

Infectious Diseases Division, Winthrop University Hospital, Mineola, NY.

Tetracycline antimicrobials entered into clinical usage in the late 1940s. Permanent dental staining from tetracyclines was first appreciated in 1956, eventually leading to avoidance of this class of antibiotics whenever possible in young children and pregnant or breastfeeding women. Doxycycline, introduced in 1967, binds calcium less avidly than prior tetracyclines and is regarded by some authorities as safe to prescribe for pregnant women and young children. Read More

Pulp canal obliteration after traumatic injuries in permanent teeth - scientific fact or fiction?

Braz Oral Res 2018 Oct 18;32(suppl 1):e75. Epub 2018 Oct 18.

Pontifícia Universidade Católica de Minas Gerais - PUC-MG, Department of Dentistry, Belo Horizonte, MG, Brazil.

Pulp canal obliteration (PCO) is a frequent finding associated with pulpal revascularization after luxation injuries of young permanent teeth. The underlying mechanisms of PCO are still unclear, and no experimental scientific evidence is available, except the results of a single histopathological study. The lack of sound knowledge concerning this process gives rise to controversies, including the most suitable denomination. 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.

Forensic thanatology and the pink tooth phenomenon: From the lack of relation with the cause of death to a potential evidence of cadaveric decomposition in dental autopsies - Case series.

Forensic Sci Int 2018 Oct 18;291:e8-e12. Epub 2018 Aug 18.

Department of Forensic Anthropology and Odontology, Scientific State Police, Goiania, Brazil; Department of Forensic Odontology, Federal University of Goias, Goiania, Brazil.

Forensic thanatology comprises the investigation of every phenomenon related to death performed through cadaveric exams. The pink tooth phenomenon (PTP) emerges as a thanatological finding registered during medical or dental autopsy. The PTP consists of a reddish or pink coloration caused in the teeth by the penetration of pulpal hemoglobin in the dentinal tubules. Read More

Effect of carbamide peroxide bleaching on enamel characteristics and susceptibility to further discoloration.

J Prosthet Dent 2019 Feb 20;121(2):340-346. Epub 2018 Aug 20.

Associate Professor, Department of Restorative Dental Sciences, Division of Prosthodontics, College of Dentistry, University of Florida, Gainesville, Fla. Electronic address:

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
