    Basic Science Mouthwashes: an in vitro study of their action on microbial biofilms and cytotoxicity to gingival fibroblasts

    Luciane Dias de Oliveira

    In an in vitro study, commercial mouthwashes demonstrated antibiofilm activity on Candida albicans, Staphylococcus aureus, Enterococcus faecalis, Streptococcus mutans, Escherichia coli, and Pseudomonas aeruginosa. The mouthwashes were more effective on bacteria than on C albicans. Cytotoxic effects on gingival fibroblasts were also observed.

  • Basic Science Effect of composite warming on shear bond strength

    Thomas F. McDaniel
    Thomas W. Sigrist
    Gary M. Johnson

    This study compared the shear bond strengths of room temperature (22°C) and prewarmed (54°C) restorative composite resin bonded to both enamel and dentin and found no statistically significant difference between the groups. Warming did not appear to affect the bond strength, but the material was subjectively judged to be easier to handle in the prewarmed composite group.

    Oral Medicine, Oral Diagnosis, Oral Pathology Medication use and medical history of 155 patients with oral lichenoid lesions: a retrospective study

    An investigation of the medication profile and medical history of 155 patients with biopsy-proven oral lichen planus (OLP) or oral lichenoid lesions (OLLs) revealed that multiple medical conditions and polypharmacy are common. Although causation cannot be fully assessed, clinicians should consider the possibility of medication as a complicating factor in patients with OLP or OLLs.

    Oral Medicine, Oral Diagnosis, Oral Pathology Use of trichloroacetic acid for management of oral lesions caused by human papillomavirus

    Martha Carmona Lorduy

    Wanda Medina Carmona

    A prospective cohort study of 20 patients with lesions caused by human papillomavirus (HPV) found that 65% of patients had focal epithelial hyperplasia, 20% had common warts, and 15% had condylomata acuminata. Application of trichloroacetic acid (TCA) to the HPV-associated oral lesions proved to be an effective nonsurgical treatment; most lesions were resolved within 45 days (3 TCA applications of 30-60 seconds each).

  • Oral Medicine, Oral Diagnosis, Oral Pathology Conservative management of a rootless premolar: a case report with 4-year follow-up

    Mahesh Ramakrishnan
    Victor Samuel

    A 9-year-old girl presented with a prematurely erupted and grossly carious permanent second premolar. The premolar was treated with a stepwise excavation, and a stainless steel crown was adapted to prevent microleakage and restoration failure. A 4-year follow-up evaluation showed remarkable healing and complete root formation.

  • Endodontics The effect of endodontic access on the failure load of lithium disilicate and resin nanoceramic CAD/CAM crowns

    Christopher Lund
    Peter Guevara

    This study evaluated the effect of endodontic access preparation and repair on lithium disilicate and resin nanoceramic CAD/CAM crowns. For the lithium disilicate crowns, the failure load was significantly higher for intact than for repaired specimens (P = 0.002). However, there was no significant difference between intact and repaired specimens for resin nanoceramic. Repairs may work under normal occlusal loads, but replacement is recommended where parafunctional occlusal loading is suspected, the crown was not adhesively cemented, or there is a defect in the crown.

    Ridge split procedures are a means to improve the chances for success of dental implants in narrow alveolar ridges. This case report presents a 3-year follow-up of 2 posterior implants placed immediately after a ridge split procedure that was performed with a piezoelectric surgical unit.

  • Restorative Dentistry The effect of time between curing and tea immersion on composite resin discoloration

    Faezeh Abolghasemzadeh

    This study evaluated the discoloration of 3 composite resins when immersed in tea solution at different timepoints up to 24 hours after curing. All discoloration was within clinically acceptable limits, but results suggested that patients should avoid the intake of colored beverages for at least 12 hours after a restoration. This restriction can decrease to 1 hour for microfilled composites.

  • Dentinal Hypersensitivity & Treatment Photobiomodulation versus direct restoration in a patient presenting with dentinal hypersensitivity: a 6-month follow-up

    This case report discusses the indications that led to the selection of different treatments for dentinal hypersensitivity in a single patient. Taking into account the different degrees of tooth wear and levels of pain, the right canine and first premolar were restored with composite resin to create a mechanical barrier against stimuli, while the left lateral incisor and canine were irradiated with a low-power laser to reduce pain levels and depolarize nerve fibers. Both treatments provided satisfactory results.

  • Implants The influence of dental implants in periapical and panoramic radiographs and cone beam computed tomography images: a clinical study

    Maria Ivete Bolzan Rockenbach

    This study analyzed the influence of dental implants on the radiographic density of the peri-implant region. Mean grayscale values were calculated in 6 areas adjacent to implants on corresponding periapical radiographs, panoramic radiographs, and cone beam computed tomography (CBCT) images. Although all images demonstrated artifacts, CBCT images suffered the greatest interference from dental implants.

    In an in vitro study of the effects of whitening mouthwash on tooth color, 48 bovine teeth were immersed in artificial saliva (control), Colgate Luminous White, or Oral-B 3D White daily for 30 days. Assessment of L*, a*, and b* values and overall color change (ΔE*) showed that the whitening mouthwashes did not improve color after 14 and 30 days.

    This study evaluated the bond strength between an yttria-stabilized tetragonal zirconia polycrystal ceramic and a luting agent. The ceramic was submitted to different surface treatments, including sandblasting and plasma etching, and bond strengths were tested before and after thermocycling. Plasma etching improved bond strength values before thermocycling, but all groups showed lower bond strength values after thermocycling.
