Laser-assisted treatment of peri-implantitis: a retrospective cohort study
Gary M. Schwarz
David M. Harris
This retrospective cohort study reports the clinical outcomes of the LAPIP protocol in 222 patients with 437 implants treated for peri-implantitis. For 264 implants in 138 patients who had follow-up data, the clinical outcomes over the median follow-up of 13.1 months were promising, with a 94% implant survival rate.

This literature review covers the available evidence for the effectiveness of garlic extracts and derivatives in the management of oral health maladies, including periodontitis and dental caries. Current promising results and the limitations of the findings warrant additional studies to gather supplemental evidence.

This article reports the case of a pediatric patient diagnosed with molar-incisor hypomineralization associated with dental fluorosis. Treatment included applications of fluoride varnish and placement of composite resin restorations in the maxillary incisors to eliminate hypersensitivity and improve esthetics. The success of the treatment was confirmed at a 12-month follow-up.

James J. Closmann
This report describes the case of a 78-year-old man with painful enlargement of the right posterior region of the mandible that caused paresthesia. Immunohistochemical analysis of a biopsy specimen was used to make the diagnosis of metastatic clear cell renal cell carcinoma in this patient, whose primary malignancy was previously unknown. Composite resection of the metastatic lesion was performed, and the mandible was reconstructed with an osteomyocutaneous free tissue transfer and a custom plate.

This case series describes management of an open apex, a furcal perforation, and a horizontal root fracture with a bioactive calcium silicate–based cement (Biodentine) as root repair material. To prevent extrusion of the cement, platelet-rich fibrin was used as an external matrix. The patients were followed for 2-3 years, and the teeth demonstrated remarkable healing.

A quantitative and visual examination of sealed restorative specimens following exposure to artificial aging

This study tested the effect of 5 different surface sealants (PermaSeal, Embrace WetBond Seal-n-Shine, OptiGuard, BisCover LV, and DuraFinish) on the surface roughness of composite resin before and after artificial aging (thermocycling). Only 1 group (DuraFinish) showed a significant increase in surface roughness following thermocycling. The use of surface sealants could be minimally beneficial for restoration maintenance if a transparent covering medium is utilized during polymerization. However, due to the effects of the oxygen-inhibited layer of unpolymerized monomers that forms if a covering medium is not used, the results suggest the benefits of surface sealants do not offset the costs.

Consequences of tooth luxation associated with complicated crown fracture: a case report

A 10-year-old patient suffered a complicated crown fracture associated with luxation of the maxillary left central incisor. The dentition was splinted at a hospital, but the exposed pulp was not treated. A dental evaluation 16 days posttrauma revealed a fracture of enamel and dentin involving the pulp, which was necrotic. Over a 10-month period, the incisor was treated with periodic changes of calcium hydroxide dressing for apexification. Two years after the trauma, a radiograph confirmed ankylosis of the traumatized tooth. When trauma affects the enamel, dentin, pulp, and supporting tissues, the prognosis can be unfavorable even when late treatment is adequate, especially when a tooth in a growing patient has points of ankylosis.

Vital pulp therapy of a dens evaginatus–affected tooth with an immature apex and inflamed pulpal and periapical tissue: a case report

Dens evaginatus (DE) is a developmental anomaly presenting as an enamel-covered tubercle on the occlusal surface of a premolar. Clinical examination of a 10.5-year-old girl suggested the presence of DE in a noncarious mandibular right second premolar with a diagnosis of symptomatic irreversible pulpitis and symptomatic apical periodontitis. A single-appointment mineral trioxide aggregate pulpotomy and an immediate composite resin restoration were performed. Recall examinations at 3, 6, and 18 months verified periapical healing and root development without clinical symptoms.

This study examined the effect of dual-cured adhesives on the bond strength of dual-cured resin cement to dentin under different polymerization conditions: with or without light curing of the dual-cured adhesive as well as with or without light curing of the dual-cured resin cement through a lithium disilicate ceramic material. The effect of light curing on the shear bond strength was product dependent. Clearfil SE Bond 2 performed significantly better with light curing of both the adhesive and cement. Less significant effects of the various light-curing and self-curing combinations were observed with ExciTE F DSC or Universal Primer. When neither the adhesive nor the cement was light cured, all 3 adhesives had a significant loss in bond strength.
