    Periodontics Antimicrobial activity of silver diamine fluoride on human periodontitis microbiota

    Thomas E. Rams

    Guillermo J. Ramírez-Martínez 
    Eugene J. Whitaker

    In an in vitro study, subgingival biofilm specimens from 24 adults with severe periodontitis were mixed with 19% or 38% silver diamine fluoride (SDF) or left untreated and then inoculated on agar. The SDF-treated specimens yielded significantly lower mean total viable counts and mean total cultivable proportional levels of red- and orange-complex periodontal pathogens than did untreated specimens (P < 0.001). No statistically significant antimicrobial differences were found between 19% and 38% SDF.

    Basic Science Effect of erosive challenge before and after the restoration of primary teeth

    Jéssica Patrícia Cavalheiro 
    Mônica Irma Aparecida Valdeci de Souza 
    Fabiano Jeremias

    The erosive effect of a soft drink on primary teeth before and after restoration was investigated in vitro on enamel blocks. The erosive challenge significantly decreased the microhardness and marginal adaptation and increased the roughness and marginal infiltration of composite resin, bulk-fill composite resin, conventional glass ionomer cement, and resin-modified glass ionomer cement, but composite resin was least affected. Erosive challenge before and after restoration altered the enamel microhardness and roughness significantly more than did erosive challenge only after restoration.

  • Pediatric Dentistry Primary mandibular molars with supernumerary roots: a report of 2 cases

    Saumya Taneja 
    Anuj Jain

    Supernumerary roots are rare in primary mandibular molars, but dental practitioners must be aware of the possibility to avoid endodontic treatment failure. This report describes 2 cases of primary mandibular second molars with supernumerary roots showing carious involvement. One tooth was successfully treated with pulpectomy, while the other was extracted and replaced with a space maintainer.

  • Oral Medicine, Oral Diagnosis, Oral Pathology Case of Mönckeberg arteriosclerosis in the carotid, facial, and lingual arteries: a potentially serious incidental finding in CBCT

    Suvendra Vijayan 
    Anitha Potluri

    Calcifications in the tunica media are more prevalent in older patients and patients with diabetes and/or chronic kidney disease. Classified as Mönckeberg arteriosclerosis, these calcifications resemble railroad tracks on imaging studies and are usually incidental findings. This case report describes Mönckeberg arteriosclerosis in the carotid, facial, and lingual arteries of a 66-year-old man.

  • Basic Science Comparison of the antimicrobial properties of charcoal-infused and non–charcoal-infused toothbrushes: an in vitro study

    Shubha P.

    This study compared retention of Streptococcus mutans and Candida albicans on charcoal-infused and non–charcoal-infused toothbrushes to assess differences in their antimicrobial properties. With both types of toothbrush, there was a statistically significant decrease in colony counts from the initial exposure to the final retention of both microbes. However, no significant differences in antimicrobial activity were found between the brush types.

  • Prosthodontics Challenges in the workflow of a digital diagnostic wax-up: a case report

    This case report demonstrates the use of digital technology to communicate with the dental laboratory during the fabrication of maxillary veneers. Although digital scans were sent to the laboratory, the laboratory completed a conventional diagnostic wax-up from printed models. A novel workflow is proposed to allow completion of the diagnostic wax-up using a fully digital method.

  • Esthetics/Cosmetic Dentistry Color stability of gingiva-colored restorative materials: an in vitro study

    The color stability of 3 gingival shades of dental restorative materials was compared to that of a tooth-colored nanohybrid composite. After specimens were randomly assigned to immersion in distilled water (control), red wine, tea, coffee, or curry solution, spectrophotometric analysis revealed that curry solution caused unacceptable color change in all of the materials, while coffee significantly affected all of the gingival shades.

    Two systemically healthy men had white and red patches consistent with oral candidiasis on the dorsal surface of the tongue. Neither patient was undergoing antibiotic or corticosteroid treatment, and both reported frequent smoking of cannabis. Oral candidiasis may occur in healthy adult patients under conditions that decrease salivary flow, including marijuana use.

  • Basic Science Influence of thickness and aging on the mechanical properties of provisional resin materials

    This study evaluated the flexural strength (FS) and modulus of elasticity (ME) of 2 provisional resins (Protemp 4 and Dencôr) at different thicknesses and after different storage periods. The 2.0-mm-thick Protemp 4 specimens presented the highest values of FS, mainly after 3 months. The ME was higher after 3 months (1.5-mm-thick specimens), regardless of the material. In addition, the higher the FS, the higher the ME of the material.

  • Sports Dentistry Relationship between the quality of life and oral health in athletes at a Peruvian university

    In a cross-sectional study of 89 university-level athletes, Spearman rank order correlation analysis revealed no statistically significant correlation between oral health and quality of life. The athletes exhibited moderate caries risk, poor oral hygiene, and probable gingivitis. However, their quality of life was not compromised by their oral health status.
