Effect of two types of charcoal toothpaste on the enamel surface roughness of permanent teeth.

Background: Charcoal in the composition of some kinds of toothpaste has created concerns regarding abrasiveness and subsequent complications. Considering the popularity of charcoal toothpaste, and the manufacturers' claims that no porosity is caused by activated carbon, this study aimed to compare the effects of two charcoal kinds of toothpaste and three conventional tubes of toothpaste on enamel surface roughness of permanent primary teeth.

Materials And Methods: This experimental study evaluated 75 teeth mounted in acrylic resin.

A comparative evaluation of the antimicrobial effect of chamomile, -green tea, and chlorhexidine mouthwashes on some oral bacterial species.

Background: Plant compounds such as , green tea, and chamomile have been increasingly used in recent years to achieve oral health. This study aimed to determine the antimicrobial effect of chamomile (Matrika), -green tea, and chlorhexidine (CHX) mouthwashes on some oral bacterial species.

Materials And Methods: This prospective experimental study investigated the antimicrobial properties of three mouthwashes, including chamomile (Matrika), -green tea, and CHX as well as distilled water as control on five bacterial species, including , , and as primary colonizers and and as secondary colonizers.

Comparative evaluation of low-level laser and systemic steroid therapy in adjuvant-enhanced arthritis of rat temporomandibular joint: A histological study.

Background: Low-level laser therapy (LLLT) has shown a promising effect in ameliorating symptoms of rheumatoid arthritis (RA). The aim of this investigation was to compare the early and late anti-inflammatory effects of LLLT and betamethasone in RA.

Materials And Methods: In this animal experimental study, after inducing a model of RA in temporomandibular joint (TMJ) of 37 Wistar rats using adjuvant injection, they were randomly distributed into three experimental groups of 12 animals each: (1) LLLT group; (2) steroid group which received a single dose of betamethasone systemically; and (3) positive control group, which did not receive any treatment.

Evaluation of dental socket healing after using of porous titanium granules: Histologic and histomorphometric assessment in dogs.

Background: Different methods have been suggested to preserve bone architecture following traumatic events such as teeth extraction. The purpose of the study was to histologically and histomorphometrically evaluate the dental socket healing after applying porous titanium granules (PTG) in dogs.

Materials And Methods: Four healthy male dogs were involved in the present 6-weeks experimental animal study.
