This study reviewed the current literature concerning implant-assisted removable partial dentures (RPDs). A review of these articles indicated that the combination of dental implants with RPDs constitutes a cost-efficient prosthetic protocol. Further studies are still needed.

This in vitro study determined the surface roughness (Ra) and absolute gloss (AG) values for 2 resin composites: a microhybrid and a microfill. Two-way ANOVA and Fisher’s LSD multiple comparisons revealed significant differences between the 2 resins (P ≤ 0.05). Pearson’s r correlation coefficient (P ≤ 0.001) indicated an inverse linear relationship between Ra and AG.

Free radicals are species capable of independent existence that contain 1 or more unpaired electrons. Free radicals can be important biomarkers for progressive inflammatory diseases of the periodontium and periapical tissues, and/or precancerous and cancerous lesions of the oral cavity. Nitric oxide (NO) is a free radical gas and an inflammatory biomarker. The aim of this paper is to present the role of NO in periodontal health and inflammation.

This study sought to compare the shrinkage of 3 resin composites after polymerization, using different curing modes and 2 methods of analysis. Curing modes differed significantly in the free linear shrinkage test group, while resin composites did not. In the wall-to-wall shrinkage group, there were significant differences between the resin composites.

The purpose of this study was to evaluate the effect of a splint on 12 symptoms: temporomandibular joint “pop,” “click,” and lock; jaw, neck, shoulder, and mouth-opening pain; headache; earache; tinnitus; and clenching and grinding of teeth. Splints were designed for 157 dental patients with mixed histories of the 12 symptoms. The results showed significant improvement (P < 0.001) in 11 of the 12 symptoms.

This article presents a case report of a 52-year-old woman who was hospitalized with a hepatic abscess after a routine periodontal maintenance procedure. Systemic antibiotic therapy, drainage of the hepatic abscess, and oral rehabilitation resulted in complete recovery.

Talon cusps in anterior teeth are relatively rare, and are characterized by the presence of an accessory cusp-like structure projecting from the cingulum area or cementoenamel junction. This article attempts to describe the variants of this anomaly with 2 case reports involving facial and bilateral palatal manifestation.

This study assesses the knowledge and perceptions of practicing dentists in relation to the risk of bisphosphonate-induced osteonecrosis of the jaw and how their knowledge and perceptions influence their decisions when developing treatment plans. Knowledge score groupings reflected differences between low knowledge and high knowledge dentists in terms of their behavior concerning patients on bisphosphonate therapy.

This article illustrates how CBCT scanning and a dental operating microscope can facilitate a better understanding of complex root canal anatomies, ultimately allowing the dentist to clean, shape, and obturate root canal systems more efficiently.

The aim of this study was to compare the effectiveness of side-vented needles vs brush-covered needles in the cleansing of root canals instrumented with oscillatory and rotary systems. No statistically significant differences were found between the groups.

This study sought to determine the effect of cyclic loading and toothbrush abrasion (with and without abrasive slurries) on cervical lesion formation. Cyclic loading and toothbrushing machines subjected teeth to 1.6 million cyclic loads and 30,000 brushing strokes, the equivalent of 4 years of function and brushing for an average patient. Load cycling had no significant effect on cervical tooth loss. Brushing with toothpaste resulted in significantly greater cervical tooth loss than brushing with water, which in turn was significantly greater than no treatment at all.

It is important to sterilize and obturate the entire expanse of the root canal system effectively to prevent endodontic failure. This article presents a case involving endodontic retreatment of a maxillary second molar with an unusual morphology consisting of 6 root canals.
