Special Patient Care The role of dental care providers in the management of patients prescribed bisphosphonates: brief clinical guidanceHassan H. AbedFull Article (PDF)
Elham N. Al-Sahafi
Dentists must be aware of the signs of medication-related osteonecrosis of the jaw (MRONJ). Patients suspected of having MRONJ should be referred to an oral surgeon to avoid complications. A bisphosphonate “drug holiday” during dental treatment is not effective in reducing the risk of MRONJ.

Microcomputed tomography revealed that hand, rotary, and reciprocating instrumentation produced similar apical enlargements in 3-rooted maxillary premolars. Reciprocating instrumentation presented some advantages over hand preparation regarding centering ability.

Basic Science Evaluation of the marginal integrity of a bioactive restorative materialBarry M. OwensFull Article (PDF)
Jeffrey G. Phebus
William W. Johnson
This study compared the marginal microleakage of a bioactive composite resin with that of a universal hybrid composite resin and a resin-modified glass ionomer in standard Class V preparations. The specimens in the bioactive material group exhibited greater microleakage at the coronal and apical margins than the specimens in the other groups, but the difference was not statistically significant. In all groups, microleakage was greater at the apical than the coronal margins.

The present article reports 3 cases in which foreign bodies inside the maxillary sinus were associated with dental treatment. Foreign bodies can migrate to the maxillary sinus during or after dental procedures such as dental extraction, implant placement, and endodontic treatment. Diagnosis and treatment are facilitated by the use of cone beam computed tomography.

A retrospective study of the clinical records of a large university referral center explored the demographic and clinical information, as well as treatment outcomes for patients with burning mouth syndrome. Although treatment effectiveness varied, and some regimens were used too infrequently to assess, many patients reported relief of symptoms. The most effective treatments were α-lipoic acid, clonazepam, oral disintegrating clonazepam, and topical vitamin E.

This case report reviews the consequences of delayed reimplantation (after 24 hours) of an avulsed maxillary central incisor. The article details the 4-year follow-up and the management of ankylosis during facial growth of the pediatric patient. A direct composite resin restoration was placed at the 3-year follow-up to improve esthetics until definitive treatment can be performed at the end of the growth period.

Restorative Dentistry Effect of fiber inserts on gingival margin microleakage of Class II bulk-fill composite resin restorationsFereshteh ShafieiFull Article (PDF)
An in vitro study evaluated the effect of fiber inserts on enamel and dentin margin microleakage of bulk-fill and conventional composite resin restorations. Fiber reinforcement in composite resins might improve enamel sealing in shallow Class II cavities. The effect of fiber reinforcement on the dentin margins of deep cavities depended on the viscosity of the composite resin; fiber reinforcement was effective for flowable bulk-fill and conventional composite resin restorations.

Endodontics Effect of root canal obturation with calcium silicate materials on pH change in simulated root resorption defectsVivek AggarwalFull Article (PDF)
This study evaluated the effect of 3 commercially available calcium silicate materials (CSMs) on pH in simulated root resorption defects. Intracanal placement of CSMs resulted in an initial pH of 9.0-9.7 inside the resorption defects; the pH gradually decreased to 8.0-8.5 over the span of 2 months. The CSM groups exhibited higher pH levels than the control group (unbuffered normal saline).

This study compared the depth of cure obtained with a perforated metal matrix to that obtained with a conventional metal or clear matrix. When tri-sited light curing was applied, use of the perforated metal band did not result in significantly different depth of cure than either conventional metal or transparent bands. Tri-sited curing resulted in significantly greater depth of cure than occlusal-only curing.

Deborah A. Dilbone
This study measured the pH values, titratable acidity (TA), and erosive potential of 6 commercial mouthrinses. Some of the tested mouthrinses had a pH lower than the critical pH of enamel and dentin. There was a significant association between an acidic pH value and higher TA. No statistically significant difference in enamel loss among the groups was observed, but certain tested mouthrinses presented an erosive potential for dentin.

Restorative Dentistry Conservative approach for molar-incisor hypomineralization: a case report and 7-year follow-upFull Article (PDF)Camila Porto Pessôa

Mariana Minatel Braga
This case report describes a conservative approach for the rehabilitation of 4 teeth extensively damaged by molar-incisor hypomineralization. Resin-modified glass ionomer cement was inserted in acetate crowns to facilitate restoration of morphology, and the crowns were adapted to the molars. After the material was light cured, the acetate crowns were removed. Some restorations were repaired or replaced during 7 years of follow-up, but the patient reported no tooth sensitivity, and there was no recurrence of caries.
