Parham Pedram, Tabassom Hooshmand, Soolmaz Heidari
This study investigated the effect of different cavity lining techniques on the marginal sealing of Class II composite restorations. A total of 36 human molar teeth, free of caries and fillings, were each prepared with two proximal Class II boxes mesially and distally. In mesial boxes, cavity liners were applied as follows: in group 1, separately cured flowable composite; in group 2, co-cured flowable composite; and in group 3, resin-modified glass ionomer (RMGI). The remaining cavities were filled incrementally with a universal restorative composite...

Immediate implant placement and provisional restoration has become a popular and well-supported method of tooth replacement in the maxillary anterior dentition. Aside from achieving osseointegration, esthetic demands have grown with better understanding of the behavior of hard and soft tissues following this mode to therapy. Stability of gingival contours, texture of the surrounding tissues, and blending of prosthetic components with the natural dentition are critical for successful outcomes to be maintained long-term...

Root coverage in the anterior mandible is challenging due to a thin gingiva, shallow vestibule, and/or high frenulum. This case series reports on the flattening of the root surface to create a new emergence profile conceived with a two-step surgical approach aimed at providing more space for the graft, increasing the thickness of the gingival margin, and getting extra soft tissue in the open area of the recession. A total of 10 patients with recessions affecting the mandibular incisors were treated to evaluate this two-step approach, which included odontoplasty of the root followed by a connective tissue graft...

The objective of this case series was to describe surgical approaches that can be used to efficiently and effectively treat peri-implantitis as measured by positive changes in clinical parameters. A total of 32 patients with 45 implants were treated surgically to eliminate peri-implantitis. Baseline clinical parameters measured prior to surgery were compared to those made 6 months postsurgery to evaluate the efficacy of each procedure. Implants demonstrating signs of peri-implantitis were treated by one of three approaches: (1) regenerative surgery, (2) osseous resective surgery, or (3) apically repositioned flap surgery...

Lateral periodontal cysts (LPCs) are rare odontogenic cysts of developmental origin. A 52-year-old man presented with an asymptomatic gingival swelling located between the mandibular left canine and first premolar, both of which were vital. Radiography showed a well-circumscribed radiolucent area and loss of the lamina dura around the tooth socket in contact with the lesion and of the interproximal buccal bone. The lesion was enucleated. The defect was immediately grafted with a 1:1 mixed autologous and heterologous bone graft covered with a collagen membrane...

This study evaluated the influence of timing after endodontic treatment and type of resin cement used on the bond strength of fiber posts to epoxy resin-obturated canals. A total of 80 bovine incisor roots were divided into four groups (n = 20). Glass fiber posts were cemented at two different times, immediately or 7 days after endodontic treatment, using either a dual-curing resin cement (RelyX ARC, 3M ESPE) or a self-adhesive resin cement (RelyX U200, 3M ESPE). Following post cementation, the samples were cross-sectioned into slices containing root dentin, cement, and fiber post at the cervical, mid, and apical root thirds...
