Comparison of shear bond strength of different types of intracanal posts in restoring extensively damaged primary anterior teeth.

Background: Severe caries in early childhood is a concern for both children receiving dental treatment and their parents. This dental disease progresses rapidly and quickly damages the coronal part of the tooth. When there is insufficient coronal structure to support a coronal restoration, using intracanal components following root canal treatment increases tooth resistance and helps provide retention for the coronal restoration.

A pro-inflammatory diet is associated with an increased odds of periodontitis: finding from a case-control study.

Objective: This study aimed to evaluate the inflammatory effect of diet using the dietary Inflammatory Index (DII) on the odds of periodontitis. We hypothesized that a diet with high DII scores (a pro-inflammatory diet) is associated with high chronic and systematic inflammation resulting in periodontitis. Periodontitis is one of the most common inflammatory diseases that affect the tissues around the tooth and results from the interaction of bacterial infection and the host immune response.

Periostin level in gingival crevicular fluid in periodontal disease: a systematic review and meta-analysis.

Background: Periostin, a secreted adhesion molecule, is a matricellular protein secreted most in periodontal ligament and periosteum. Periostin is also needed for integrity and maturation of periodontal tissue. This meta-analysis was conducted to compare the gingival crevicular fluid (GCF) periostin levels in subjects having periodontal disease and healthy periodontium.

Effects of laser irradiation and tooth mousse on tooth hypersensitivity after office bleaching: A non-randomized clinical trial.

Background: This study aimed to assess the effect of laser irradiation and Tooth Mousse on tooth hypersensitivity (TH) after office bleaching (OB).

Materials And Methods: This clinical trial, parallel-design split-mouth nonrandomized was conducted on 30 patients requiring OB. After scaling and fabrication of a custom tray, 35% hydrogen peroxide was applied on all teeth, and 940 nm diode laser (10 W, Class IV, 110-240 V) was irradiated to the upper and lower right quadrants.

Which audio distraction technique is more effective for reduction the pain and anxiety of pediatric dental patients; "music" or "kids-story"? A randomized split-mouth crossover clinical trial.

Objective: Control of pain, fear, and anxiety of children during dental procedures is a major challenge in pediatrics. This study aimed to compare the effect of audio distraction by music and audio-story on pain and anxiety of children during dental treatment.

Methods: This randomized crossover clinical trial evaluated 60 systemically healthy children between 4 and 8 years, who were candidates for pulpotomy and steel crown of bilateral primary maxillary first or second molars.

The Rate of Demineralization in the Teeth Prepared by Bur and Er:YAG Laser.

The present in vitro study evaluated the recurrence rate of caries following cavity preparations with bur (conventional technique) and irradiation by Erbium:Yttrium- Aluminum-Garnet (Er:YAG) laser through micro hardness test. A total of 72 human extracted molars were randomly divided into 3 groups and class 5 cavities were prepared on them with 3 different methods: G1) conventional bur, G2) Er:YAG laser irradiation alone and G3) laser irradiation + laser treatment. The specimens were immersed in the artificial caries solution with pH of 2.

Comparison of Dentin Permeability After Tooth Cavity Preparation with Diamond Bur and Er:YAG Laser.

Objectives: The aim of this study was to compare the permeability of dentin after using diamond bur and Er:YAG laser.

Materials And Methods: Seventy-two recently extracted, intact, and restoration-free human permanent molars were used in this study. The samples were randomly divided into three groups of 24 each and class I cavities were prepared as follows.
