Effect of Piper betle extract on anti-candidal activity, gelation time, and surface hardness of a short-term soft lining material.

The purpose of this study was to evaluate anti-candidal activity, gelation time, and surface hardness of a short-term soft lining material incorporated with varying concentrations of Piper betle extract (0.25 to 20% w/w). Agar-diffusion assay was conducted to evaluate an inhibitory effect against Candida albicans.

Effect of mouth-motion fatigue and thermal cycling on the marginal accuracy of partial coverage restorations made of various dental materials.

Objectives: To investigate the influence of mouth-motion fatigue on marginal-accuracy of partial-coverage-restorations-(PCRs) of various dental materials.

Methods: Eighty molars were prepared equally and divided into five groups (n=16). PCRs were fabricated of following dental materials: Group-GO=Gold-Pontor-MPF(double dagger), Group-TA=Targis*, Group-EX=IPS-e.

All-ceramic partial coverage restorations on natural molars. Masticatory fatigue loading and fracture resistance.

Purpose: To determine the reliability and fracture resistance of adhesively luted all-ceramic partial coverage restorations (PCR) on natural upper molars after masticatory fatigue loading.

Methods: 64 maxillary molars were divided into four groups of 16 specimens each. Control Group NP remained unprepared.

Long-term survival of endodontically treated molars without crown coverage: a retrospective cohort study.

Statement Of Problem: Teeth are weakened after endodontic treatment and should, ideally, be crowned, especially posterior teeth. However, this is not always possible. Information about the longevity of endodontically treated teeth without crown coverage may assist in selecting appropriate treatment modalities.

Fracture strength of all-ceramic lithium disilicate and porcelain-fused-to-metal bridges for molar replacement after dynamic loading.

The replacement of missing posterior teeth using all-ceramic bridges remains a challenge. This study compares the fracture resistance of all-ceramic 3-unit bridges for the replacement of first molars to conventional porcelain-fused-to-metal bridges. Human premolars and molars were used to create two test groups and one control group of 16 specimens each.
