    This in vitro study sought to evaluate the biomechanical action on microorganisms and endotoxins of sodium hypochlorite (NaOCl) and an intracanal medication containing Zingiber officinale, associated with calcium hydroxide. The results showed that the NaOCl eliminated 100% of root canal microorganisms and reduced endotoxins immediately and 7 days after preparation by 88.8% and 83.2%, respectively.

  • Surgical Endodontics Concurrent intentional replantation of maxillary molars using a novel root-end filling

    Saeed Asgary, DDS, MS
    Ali Nosrat, DDS, MS

    2014 May/Jun; 62(3):30.  

    This article describes the successful concurrent intentional replantation of 2 maxillary molars. Teeth No. 14 and 15 were sensitive to percussion and palpation. Radiographs revealed a large periapical radiolucent lesion and inadequate root canal filling in both teeth. Tooth No. 14 was extracted, root-end resection and root-end preparation was completed, and the cavities were filled with calcium enriched mixture cement. The tooth was replanted, and the same procedure was done for tooth No. 15. Follow-ups revealed no signs of inflammation or resorption. The periapical lesion was healed at 24 months.

  • Sports Dentistry & Mouthguards Role of mouthguards in reducing mild traumatic brain injury/concussion incidence in high school football athletes

    Jackson Winters, DDS
    Richard DeMont, PhD, CAT(C), ATC

    2014 May/Jun; 62(3):34.  

    The purpose of this randomized prospective study was to compare the impact of pressure-laminated (LM), custom-made, properly fitted MGs to over-the-counter (OTC) MGs on the MTBI/concussion incidence in high school football athletes over a season of play. There was a significant difference (P = 0.0423) with incidence rates of 3.6% and 8.3% in the LM MG and OTC MG groups, respectively.

    Oral Medicine, Oral Diagnosis, Oral Pathology Distinguishing and diagnosing contemporary and conventional features of dental erosion

    Mohamed A. Bassiouny, PhD, DMD, MSc

    2014 May/Jun; 62(3):46.   

    Dental erosion associated with modern dietary habits can exhibit unique features that symbolize a departure from the decades old conventional image known as tooth surface loss. In this article, contemporary and conventional erosion lesions are distinguished from similar defects, such as mechanically induced wear, carious lesions, and dental fluorosis.

    Caries Detection and Prevention Microtensile bond strength of etch-and-rinse and self-etch adhesives to artificially created carious dentin

    2014 May/Jun; 62(3):56.  

    This article evaluates a pH-cycling model for simulation of caries-affected and caries-infected dentin (CAD and CID, respectively) surfaces, by comparing the bond strength of an etch-and-rinse and a self-etch adhesive system. For both adhesives, bonding to sound dentin (SD) showed that the microtensile bond strength (µTBS) values of SD, CAD, and CID were SD > CAD > CID (P < 0.05). The type of dentin and its histological structure played an important role in etch-and-rinse and self-etch bonding, as lower µTBS values were attained in CAD and CID.

  • Prevention/Diet/Nutrition Which is a stronger indicator of dental caries: oral hygiene, food, or beverages? A clinical study

    Poonam Jain, BDS, MS, MPH
    Julie J. Gary, MPH

    2014 May/Jun; 62(3):63.  

    This article presents a cross-sectional study of 76 people living in a fluoridated community. The amount of sugar-sweetened beverages and snack food consumed, plaque index, and age showed statistically significant relationships with the outcome variable—dental caries (P < 0.05). The results indicated that dietary factors and oral hygiene both contribute equally to dental caries in this study population. Sugar-sweetened beverage consumption was a much stronger indicator of dental caries than snack food consumption.

    2014 May/Jun; 62(3):e7.  

    This in vitro study evaluated how surface conditioning from bracket and mechanical cycling aging affected the bond strength and adhesive index between metallic brackets and bovine enamel. Mechanical cycling did not change bond strength to a statistically significant degree. Silicatization associated with a silanization treatment boosted the adhesive index. However, it also led to enamel fractures.

    2014 May/Jun; 62(3):e12.  

    A 32-year-old man complained of swelling after an extraction in the left maxillary premolar area. The first premolar showed no caries while the second premolar had a crown. Histopathology revealed the fragment to be a cemental tear, associated typically with old age or trauma. Dentists should be aware of this rare entity in cases of noncarious odontogenic pain.

Transillumination, bite test, surgical site visualization, and high-end diagnostic modalities were not considered. PPG was confirmed only after the tooth was extracted and observed under a dental operating microscope.
