DOC ranged between 52-95%. FBF composite exhibited the lowest overall hardness numbers. At 2-mm thickness, all the samples achieved an appropriate DOC. However, at 4mm thickness, only the light shades for FBF and TNF samples achieved a DOC very close to 0.8. At 4-mm thickness, the light shades for FBF, TNF and FZ samples exhibited significantly higher DOC compared to dark shades. For 4-mm-thick samples, the DOC of Filtek™ Bulk Fill (dark and light shades (and the DOC of Tetric® Bulk Fill (light shade (were different in flowable type from the sculptable type.

The shade and the viscosity of bulk-fill composites influence their DOC at 4-mm depths. Moreover, 20 seconds of light curing appears insufficient for 4mm thickness of bulk-fill composite.

Periodontitis is one of the most common bacterial infections of the oral cavity. It is important to find adjunctive methods for chemical treatment of periodontitis with less complications and proven therapeutic properties.

The aim of this study was to compare the effects of
and
on antioxidant, anti-inflammatory and histopathologic indices of induced periodontitis in male rats.

In this experimental animal study, forty adult male Sprague-Dawley rats were randomly divided into 4 groups (n=10) and then experimental periodontitis was induced by 3-0 nylon non-absorbable ligature. click here Each group was treated for 10 days as follows 1)
hydroalcoholic extract, 1000 mg/kg/daily, orally; 2)
hydroalcoholic extract, 1000 mg/kg/daily, orally; 3) a mix of the two plants, 1000 mg/kg/ daily, orally, 4) normal saline solution. At the end of study, blood sample were obtained via cardiocentesis, the rats were euthanized, and their maxillae were removed. The samples were analyzed for histopathological scores and total antioxidant capacity and IL-1β were measured.

Mixed hydroalchoholic extract of
and
decreased IL-1β (4.3020±0.63), and increased the antioxidant parameter in comparison to the control group (3.1192±0.43) (
< 0.001). There were significant histopathological differences between the treatment groups and the control group.

Mixed hydroalchoholic extract of
and
might be considered as an adjunctive treatment for periodontitis.
Mixed hydroalchoholic extract of H. perforatum and C. officinalis might be considered as an adjunctive treatment for periodontitis.
Some patients may report moderate-to-severe pain and/or swelling following root canal treatment, which is undesirable for both the patient and dentist and may require an unscheduled emergency visit by patients to relieve their symptoms.

The aim of this study was to evaluate the post-treatment flare-up incidence following application of nano zinc oxide-eugenol (NZOE) sealer in mandibular first molars with irreversible pulpitis.

This single-blinded study was performed on 60 patients having mandibular first molars with irreversible pulpitis. After signing the written consent form, the patients were randomly divided into two groups considering their age range (20-34 and 35-50 years). Individuals without systemic diseases and with a first mandibular molar diagnosed with irreversible pulpitis due to caries, no sinus track and abscess, normal periapical radiographic appearance, no spontaneous pre-treatment pain, not taken any medication for at least 8 hours before the treatment visit were included in this studyreceiving root canal therapy.
Many efforts have been made to improve the properties of mineral trioxide aggregate (MTA), including the incorporation of nanoparticles.

The aim of this study was to investigate the incorporation of zinc oxide and hydroxyapatite nanoparticles on the compressive strength of white MTA (WMTA).

In this in vitro study, the following materials were evaluated MTA, MTA+5% zinc oxide (ZnO) nanoparticles, MTA+10% zinc oxide nanoparticles, MTA+5% hydroxyapatite (HA) nanoparticles, MTA+10% zinc oxide nanoparticles. The compressive strength of the groups under investigation was measured on days 4 and 21 after mixing the MTA using a universal testing machine. Two-way ANOVA test was used to compare the groups and determine the significance of the effect of time and material on the compressive strength (
<0.05).

The highest and lowest compressive strength values were respectively measured for the second group, MTA/21 days, and the fourth group, MTA+Nano ZnO/4 days. Two-way ANOVA indicated that incorporation of zinc oxide and hydroxyapatite nanoparticles into MTA did not have a significant effect on compressive strength (
= 0.05). Compressive strength in all the groups increased over time from day 4 to day 21. However, this increase was not statistically significant (
= 0.06) except for the MTA group, which exhibited significant increase in compressive strength over time from day 4 to day 21 (
=0.007).

Incorporation of HA and ZnO nanoparticles into MTA had no detrimental effects on its strength and these nanoparticles can be used to improve the other properties of MTA.

Oral self- care is an important aspect of lifestyle anda serious public health issue.

This study aimed to evaluate the effect of an educational program based onthe theory of planned behavior (TPB) on the mothers and children's oral self-carebehaviors.

This quasi-experimental study was conducted on 148 mothers andtheir children (1-6 years)who referredto the health centers of Tabriz, Iran ; divided into two groups of intervention(n=74) and control(n=74).Data were collected through a questionnaire that included demographic characteristics, oral self-care behaviors, andstructures of TPB. Both groups completed questionnaires before, immediately, 3 and 6months after the intervention. The experimental group received three educational sessions, each session held for 120 minutes. The educational methods such as lectures, group discussion, and demonstrations were used. Data were analyzed using SPSS (ver18) software and Chi-square, Independent samplest-testand repeated measure ANOVA at the significant level of < 0.
