Gingival microleakage of class II resin composite restorations with fiber inserts

- El-Mowafy, W El-Badrawy, A Eltanty, K Abbasi, N Habib

As Esthetics has become a key factor in Restorative Dentistry, Tooth colored restorations especially resin composites have become the treatment of choice for most patients. However the volumetric polymerization contraction of these materials can result in gap and microleakage. Microleakage is the most frequently encountered problems with posterior composite restorations, especially at the gingival margins. This study determined the effect of glass and polyethylene fiber inserts on reducing the gingival marginal gap in class II resin composite restorations with the gingival margins on the root surface. Fifty-four intact molars were measured in the study. Class II slots were prepared in these teeth on both proximal sides of each tooth with gingival margin on the root surface. These teeth were divided into nine groups. Both glass fiber and polyethylene with three different bonding agents were used. The groups which were filled with Clearfil SE Bond (Kuraray)/Filtek P60 (3M/ESPE) combination produced the lowest degree of microleakage.It was evident that the use of fiber inserts markedly reduced the amount of microleakage at the gingival floor of Class II composite restorations.

Comparison of the percentage of Gutta-percha-filled area obtained by Thermafil and System B

- G De-Deus, C M Maniglia-Ferreira, Gurgel-Filho, Paciornik, Machado, Coutinho-Filho

One of the prime goals for a successful endodontic treatment is to completely fill the root canal space with an inert material and to achieve a good apical seal. There are several techniques that have been developed over a period of time for the purpose of obturation. Use of a thin layer of sealer is recommended as certain sealers can get dissolved over a period of time. This study compared the percentage of gutta-percha-filled area (GPFA) obtained by three different methods, Thermafil, System B and lateral condensation. Around fourty-five Human mandibular first molars were considered in the study. These teeth were divided into three different groups. Each group for one particular technique of obturation. After preparation and obturation, these teeth were sectioned and photomicrographs and digital analysis was done. The result showed that the Thermafil system produced significantly higher GPFAs when compared to the other two techniques. Thus it suggests that Thermafil system can reduce sealer and voids thus achieving the goals of a successful obturation.

Fracture resistance of upper and lower incisors restored with glass fiber reinforced posts

- Marc Schmitter, Claudia Huy, Brigitte Ohlmann, Olaf Gabbert, Herbert Gilde, Peter Rammelsberg

Fiber reinforced posts (FRP) have been introduced in the late decade and is commonly used in practice these days. The aim of this study was to evaluate the fracture resistance of Upper and lower incisors restored with glass fiber reinforced posts. 32 Upper and 32 Lower incisors were endodontically treated and FRPs were cemented, using pretreated (Rocatec) and non-pretreated posts.Crowns were fabricated and cemented with Ketac-cem or Panavia.Eight upper and lower incisors were used as control group.Rocatec used to pretreat the posts and crowns cemented using an adhesive cement appear to reduce the risk of clinical failure.

Combined therapy in the treatment of dens invaginatus: Case report

- Pedro Ortiz, Rebeca Weisleder, Yolanda Villareal de Justus

Dens Invaginatus is a development defect resulting from invagination of the crown before calcification has occurred. The incidence is higher in maxillary permanent lateral incisors followed by central incisors. This is a case of a maxillary right lateral incisor with Dens Invaginatus also presenting with necrotic pulp and chronic periradicular abscess. A surgical and a non-surgical therapy was planned for the patient as non-surgical endodontic treatment was not adequate, because only two canals were found during this procedure,but radiographically a third canal was evident, which was confirmed at the time of surgery. When considering Dental anomalies, treatment plan should have an interdisciplinary approach.
