Antimicrobial photodynamic therapy against Lactobacillus casei using curcumin, nano-curcumin, or erythrosine and a dental LED curing device.

This study aimed to investigate the photodynamic effects of curcumin, nanomicelle curcumin, and erythrosine on Lactobacillus casei (L. casei). Various concentrations of curcumin (1.

Distal guide as a substitute for distal shoe space maintainer: a case series study.

Early loss of the primary second molar (DSM) before the eruption of the permanent first molar (PFM) may result in its mesial drift during the eruption. Traditionally, a distal shoe space maintainer is used in this situation to control the path of eruption and preserve the space. However, considering its disadvantages, an alternative appliance needs to be developed for guiding the unerupted PFM.

Management of oral mucositis in pediatric patients receiving cancer therapy: A systematic review and meta-analysis.

Background: One of the most common complications of cancer chemotherapy is oral mucositis (OM). OM affects more than 75% of patients undergoing chemotherapy and represents a significant burden to patients and caregivers. We performed a systematic review and meta-analysis of published studies to investigate the effects of agents and techniques in reducing OM.

Antimicrobial photodynamic therapy of Lactobacillus acidophilus by indocyanine green and 810-nm diode laser.

This study investigated the efficacy of photodynamic therapy (PDT) using EmunDo as a photosensitizer against Lactobacillus acidophilus. A gallium aluminum arsenide diode laser was used in this experiment (810 nm, CW). Standard suspensions of Lactobacillus acidophilus were divided into six groups by treatment: 1) EmunDo, 2) diode laser (100 mW, 90 s), 3) diode laser (300 mW, 30 s); 4) EmunDo + diode laser (100 mW, 90 s), 5) EmunDo + diode laser (300 mW, 30 s), 6) control (no treatment).

CPP-ACP: Effect on Dental Plaque Acidity after Water Rinsing Following Topical Fluoride Therapy.

Objectives: There is some evidence that water rinsing immediately after topical fluoride therapy has the potential to reduce the effectiveness of fluoride. The aim was to determine if covering fluoridated teeth with a layer of mousse containing CPP-ACP could prevent the adverse effect of rinsing on fluoride and consequently its buffering effect on dental plaque pH during cariogenic challenge.

Study Design: This randomized, controlled, crossover, in situ study was conducted on 25 participants.

Clinical evaluation of fiber-reinforced composite crowns in pulp-treated primary molars: 12-month results.

Objective: The aim of this study was to evaluate the clinical performance of tooth-colored fiber-reinforced composite (FRC) crowns in pulp-treated second primary mandibular teeth.

Materials And Methods: This split-mouth randomized, clinical trial performed on 67 children between 3 and 6 years with two primary mandibular second molars requiring pulp treatment. After pulp therapy, the teeth were randomly assigned to stainless steel crown (SSC) or FRC crown groups.

Microhardness of composite resin cured through different primary tooth thicknesses with different light intensities and curing times: In vitro study.

Objective: The aim of this study was to evaluate the effect of increased exposure time and light intensity on microhardness of cured composite through different thicknesses of tooth structure in primary teeth.

Materials And Methods: One hundred and seventy cylindrical resin composite specimens were prepared. All specimens were divided into 17 experimental and control groups.

Localized idiopathic root resorption in the primary dentition: Review of the literature and a case report.

Idiopathic root resorption (IRR) is an infrequent condition that is usually found as an accidental finding on radiography. A significant number of cases of IRR in permanent dentition have been presented but are rarely reported in primary dentition. The aim of this case report is to present a case of localized IRR in a 7-year-old boy.

Effects of sealant, viscosity, and bonding agents on microleakage of fissure sealants: An in vitro study.

Objective: The aim of this study was to evaluate the effects of enamel or dentin bonding agent (DBA) and sealant viscosity on sealant microleakage.

Materials And Methods: Sixty extracted human premolars were randomly divided into two equal groups (based on sealant viscosity) and each group was divided into three subgroups of 10 teeth. Group 1 (low viscosity sealant, Seal-Rite, Pulpdent, USA with 7.

In vitro investigation of heat transfer phenomenon in human immature teeth.

Background and aims. Heat generated within tooth during clinical dentistry can cause thermally induced damage to hard and soft components of the tooth (enamel, dentin and pulp). Geometrical characteristics of immature teeth are different from those of mature teeth.

Effect of water rinsing after acidulated phosphate fluoride gel on dental plaque acidity: an in situ study.

Purpose: This study's purpose was to determine whether rinsing with water or cleansing teeth after topical fluoride therapy affected plaque acidity.

Methods: This randomized, controlled, crossover, in situ study was conducted on 25 dental students who wore an acrylic mandibular appliance containing one enamel block. The patients were subjected to four treatment protocols involving acidulated phosphate fluoride (APF) application followed by rinsing the mouth with water: (1) after 30 minutes (APF-30); (2) after 15 minutes (APF-15); (3) immediately (APF-0); after cleansing the teeth with a cotton roll immediately following APF (APF-cotton); or (4) no fluoride therapy (control).

Sodium hypochlorite vs formocresol as pulpotomy medicaments in primary molars: 1-year follow-up.

Purpose: The study evaluated the effects of 3 percent sodium hypochlorite (NaOCl) and formocresol (FC) as pulp dressing agents in pulpotomized primary molars.

Methods: One hundred children between three and six years each with at least one primary mandibular second molar requiring pulpotomy were randomly allocated to two groups (of 50 each). All the teeth received stainless steel crown after conventional pulpotomy procedure with either NaOCI (applied for 15 second) or FC (applied for one minute).
