Objectives: Emerging from earlier case reports the potential benefits of 38 % silver diamine fluoride (SDF) in addressing pathogenic biofilms and mitigating gingival inflammation and enlargement have sparked interest. Our study aimed to evaluate the efficacy of 38 % SDF in reducing gingival inflammation and plaque accumulation in older adults living in retirement-homes.

Methods: This 7-week randomized, controlled, double-blinded pilot trial employed a parallel assignment design.

Background: Children with Special Health Care Needs (CSHCN) have higher rates of oral diseases and tooth decay compared with the general population. Children with developmental disorders/ disabilities (DD) are a subset of CSHCN whose oral health has not been specifically addressed. Therefore, this study had two objectives: to describe the oral health needs (OHN) of children with DD compared with children without DD; and to assess barriers to access to care, utilization of dental services, and their association with oral health needs for children with DD.

Objectives: To compare efficacy of casein phosphopeptide (CPP)-amorphous calcium phosphate (ACP) fluoride varnish and light-curable resin modified glass ionomer fluoride varnish (FV) in preventing white spot lesions and evaluating acid etching prior to CPP-ACPFV application on its efficacy.

Materials And Methods: Molars and premolars were transected and halves divided into four groups (n = 18/group): (1) resin-modified glass ionomer FV: etched and Clinpro-XT varnish (3M ESPE, Pymble, New South Wales, Australia) application; (2) CPP-ACPFV: MI varnish (GC America, Alsip, IL) application; (3) Etch+CPP-ACPFV: etched and MI varnish application; (4) Control: etched and no surface treatment. To simulate 12 weeks in an intraoral environment, samples were subjected to thermocycling, brushing, and pH cycling.

Objectives: To compare the efficacy of casein phosphopeptide (CPP)-amorphous calcium phosphate (ACP) MI Varnish (GC America, Inc, Alsip, IL) and ProSeal (Reliance Orthodontic Products, Itasca, IL) sealant in preventing the development of white spot lesions (WSLs) in orthodontic patients.

Materials And Methods: This prospective randomized clinical trial included 40 orthodontic patients 12-17 years of age. One group had sealants placed on their anterior maxillary teeth, with reapplications every 3 months.

Objectives: To evaluate the preventive effects of different time intervals between repeated applications of the CPP-ACP fluoride varnish on enamel demineralization.

Methods: Human teeth were sectioned and randomly allocated to three groups: 4-week, 6-week, and 12-week (N = 22/group). Baseline images of the enamel surfaces were obtained using the FluoreCam recording the area, intensity, and impact of baseline enamel demineralization.

Objectives: To quantify differences in the etch quality of enamel within and between human teeth, which has not previously been attempted.

Materials And Methods: The buccal right and left halves of 27 extracted human teeth were randomly allocated to scanning electron microscopy (SEM) or micro-computed tomography (μCT) for evaluation. The buccal surfaces were pumiced, etched with 37% phosphoric acid gel etchant for 15 seconds, rinsed, and air dried.

Objective: To evaluate our experience with intravitreal melphalan chemotherapy as a second-line regimen for RB patients with refractory or recurrent vitreous seeds.

Methods: A retrospective case series of 16 eyes from 16 patients with intraocular RB who received intravitreal melphalan chemotherapy using the antireflux injection technique. Data included demographics, stage at diagnosis, treatment modalities, side effects, eye salvage, and survival.

Aim: To determine whether caries risk factors, including cariogenic bacterial levels and salivary function, can be used to identify orthodontic patients who develop white spot lesions (WSL).

Methods: This prospective case-control study comprised 50 patients 11-17 years of age, including 25 controls and 25 cases who developed new WSL during treatment. WSL, oral hygiene and fluorosis were evaluated from intraoral photographs.

Aim: The aim of the present study was to compare the effects of carbon dioxide (CO ) laser and casein phosphopeptide amorphous calcium phosphate (CPP-ACP)fluoride varnish on enamel demineralization.

Methods: Human teeth were randomly assigned to three groups. The enamel was treated with fluoride varnish, 10.

Objectives: To test how long casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) fluoride varnish prevents enamel demineralization in vitro.

Materials And Methods: Human molars and premolars were sectioned buccolingually and randomly assigned to two groups. Standardized pretreatment images of enamel surfaces were obtained using FluoreCam.

Chronic HCV with its longstanding complications of cirrhosis and HCC is a highly prevalent and challenging problem in Egypt. Recently, microRNAs are ranked as potential biomarkers for early diagnosis of HCV related complications. The aim of the present study was to evaluate the role of miRNA-122 and miRNA-155 for prediction of progression of HCV infection and for diagnosis of HCC.

Aim: In the present study, we tested the reliability and validity of a new light fluorescence device, the FluoreCam.

Methods: Twenty-five human teeth were sectioned mesiodistally into halves. Group 1 (n=30) included specimens with either sound enamel or natural white-spot lesions (WSL).

Aim: The aim of the present study was to compare the effectiveness and practicality of two commonly-used protocols for white spot lesion creation.

Methods: Sound posterior human teeth were sectioned into halves and randomly allocated into two groups (n=20). Using the FluoreCam system, the enamel surfaces were imaged under standardized conditions, and baseline data (area, intensity, and impact) were recorded.

The aim of the study was to evaluate the association between the gene polymorphisms in interleukin-10 (IL-10) and interferon gamma (IFN-γ) genes with susceptibility and severity of hepatitis C virus (HCV) infection among Egyptian patients. Interleukin-10 -592 A/C, -1082 G/A and IFN-γ +874 T/A genotypes were determined in 100 chronic HCV patients and 50 healthy controls using restriction fragment length polymorphism (RFLP) and the amplification refractory mutation system-polymerase chain reaction (ARMS-PCR) respectively. IL-10 -592 A/C polymorphism genotyping revealed that the frequency of CC genotype was significantly higher in chronic HCV patients than in controls (58% versus 30%, P < 0.

Studies demonstrated a significant synergism between fluoride and laser in reduction of enamel solubility. However, minimal research has focused on testing the sequence of their application and no other research investigated the preventive effect of repeated applications of a combined treatment. This study investigated the effect of two applications of fluoride-laser sequence on the resistance of sound enamel to cariogenic challenge compared to one-time application.
