Effect of C-factor and LED Curing Mode on Microleakage of Class V Resin Composite Restorations.

Objectives: To investigate the effects of cavity C-factor and LED curing mode on microleakage of class V resin composite restorations.

Methods: Eighty extracted human maxillary premolars were divided into four groups. In groups I and II, V-shaped class V cavities (C-factor ≈ 1.

Site-specific gingival bleeding on probing in a steady-state plaque environment: influence of polymorphisms in the interleukin-1 gene cluster.

Background: We previously reported a high prevalence of a combination of alleles 2 at positions interleukin (IL)-1A(-889) and IL-1B(+3954) in an Arabic population with gingivitis. In a steady state, the proportion of sites with bleeding on probing (BOP) was consistently reduced. The aim of the present study is to expand this observation by considering the site level.

Repeatability of ultrasonic determination of gingival thickness.

The aim of the present study was to assess the degree of disagreement of ultrasonic measurements of gingival thickness at different teeth. Gingival thickness was determined in 33 volunteers with plaque-induced gingivitis. Facial/buccal gingiva was measured at the level of the gingival sulcus depth.

The radiographic outcomes of direct pulp-capping procedures performed by dental students: a retrospective study.

Background: The decision between pulp capping and root canal therapy after pulp exposure is a clinical issue. The aim of the authors' study was to evaluate the outcome of direct pulp-capping procedures performed by dental students.

Methods: The authors followed the treatment outcomes of 193 patients with 204 pulp exposures with direct pulp capping.

Dental health attitudes and behaviour among dental students in Jordan.

Objective: Examine and compare differences in oral health attitudes and behaviour among Jordanian dental students.

Basic Research Design And Participants: Cross-sectional study of 314 dental students was conducted to compare differences in oral health behaviour and attitudes among these students in different levels of academic education.

Setting: Jordan University of Science and Technology.

A prospective clinical study of mineral trioxide aggregate for partial pulpotomy in cariously exposed permanent teeth.

The aim of this study was to evaluate the success of using gray mineral trioxide aggregate (MTA) for partial pulpotomy in cariously exposed young permanent first molars. Thirty-one first permanent molars of 23 patients with a carious exposure were treated using a partial pulpotomy technique. The age of the patients ranged from 7.

Smoking prevalence and its effect on dental health attitudes and behavior among dental students.

Objective: To determine smoking prevalence and its effect on dental health attitudes and behavior among dental students in Jordan.

Subjects And Methods: A cross-sectional study of 314 dental students was conducted at Jordan University of Science and Technology. Subjects were surveyed using a modified version of the Hiroshima University Dental Behavior Inventory (HU-DBI) questionnaire.

Gutta-percha retreatment: effectiveness of nickel-titanium rotary instruments versus stainless steel hand files.

This study compared the cleanliness of the root canal walls after retreatment using nickel titanium (NiTi) rotary and stainless steel (SS) files. Also compared were time of retreatment and canal deviation. Forty extracted canines were step-back prepared and obturated with gutta-percha and sealer.
