To evaluate the antifungal efficiency of various intracanal medicaments against
.
One-hundred and forty extracted human mandibular premolar teeth were decoronated, and the biomechanical preparation was done in crown-down technique. 10 μL culture suspension of
was placed into the prepared root canal space of all the teeth. After 21 days of incubation, all the teeth were randomly divided into 7 groups with 20 teeth per each group. Group I triple antibiotic powder (TAP) mixed with 3% chitosan solution; group II TAP mixed with macrogol-propylene (MP) glycol; group III chlorhexidine-guttapercha (CHX-GP); group IV Vitapex; group V 2% chlorhexidine gel; group VI calcium hydroxide paste; group VII normal saline with cotton (positive control) were used as intracanal medicaments, and the samples were incubated for 14 days. Intracanal medicaments were then completely removed using the canal brush. Dentinal chips were harvested from the walls of the root canal space in all samples using Gates-Glidden drills, were transferred into test tubes containing saline, and were serially diluted and placed in 140 Sabouraud dextrose agar plates, incubated at 37°C for 48 hours. Colony forming units (CFUs) of
were then counted using the digital colony counter.
One-way ANOVA test showed statistically significant difference among the seven groups, as the
value was < 0.001. Tukey's
test showed intergroup comparison between group I and group V; group II and group III were statistically nonsignificant as
value was >0.05.
2% chlorhexidine gel and TAP mixed with 3% chitosan solution showed superior antifungal efficiency against
.
Chitosan solution's inherent antifungal efficiency and slow and controlled drug release make it as an effective alternate carrier in mixing it with TAP instead of mixing TAP with MP.

To evaluate nanohardness of normal and fluorosed enamel in teeth restored with Cention N (CN), Equia forte (EF), glass ionomer cement (GIC), and resin composite using the nanoindentation test.
Eighty freshly extracted human premolars were selected. Standardized cavities were prepared on the buccal surface of normal (40) and fluorosed (40) teeth. Based on the type of the restorative material, the teeth were subgrouped into (
= 10) CN, EF, Type VIII GIC, and Tetric N-Ceram (TNC). The teeth were subjected to pH cycle (progressive caries test), which consisted of alternative demineralization (18 hours) and remineralization with artificial saliva (6 hours) for 3 consecutive days. Surface nanohardness was determined using a nanoindenter at distances of 100, 200, and 300 μm from the restoration-tooth margin. A polarized light Microscope was used to correlate the effect of remineralization on the enamel. Data were analyzed by one-way ANOVA with the Scheffe's
and independent
-test.

The present study was conducted to assess the
anticancer effects of
J. Presl extract and its active constituents, such as cinnamaldehyde, 4 hydroxycinnamic acid, and eugenol on oral squamous cell carcinoma cell line.
Aqueous, ethanolic, and hydroalcoholic extracts of
J. Presl (bark) were prepared using standardized protocols. Cinnamaldehyde, 4 hydroxycinnamic acid, and eugenol were quantified in the extracts. Total saponins, tannins, and polyphenols were quantified in the selected extracts. A commercially available SCC-25 cell line was cultured according to standard protocol. The anticancer effects of the extract, active compounds, and standard cisplatin were assessed by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) cytotoxicity, acridine orange/ethidium bromide staining, DNA, fragmentation assay, cell cycle analysis by flow cytometry, and JC-1 staining (5,5',6,6'-tetrachloro1,1',3,3'tetraethylbenzimidazolylcarbocyanine iodide).
The hydroalcoholic extracts demonstrated a higher quantity of the active ingredients cinnamaldehyde, 4 hydroxycinnamic acid, and eugenol. The selected extract and active compounds demonstrated anticancer effects via apoptosis induction and S-phase arrest. Apoptosis induction was exerted by the extract via alteration in mitochondrial membrane potential.
J. Presl and its active compounds exhibited
anticancer effects on oral squamous cell carcinoma. Further studies in animal models have to be carried out to assess toxicity and
effects.
The anticancer properties of
J. Presl could be explored further for prevention and management of oral squamous cell carcinoma.
The anticancer properties of Cinnamomum verum J. Presl could be explored further for prevention and management of oral squamous cell carcinoma.
Epidemiological studies of sleep disturbances are essential to promote awareness among families and educational officials and deliver appropriate treatment at a very early timing. The aim of this population-based study was to determine the frequency of sleep-disordered breathing (SDB) symptoms and its association with obesity among schoolchildren in West Saudi Arabia.
This cross-sectional study comprised 2,000 schoolchildren aged 6-12 years. Sleep-disordered breathing symptoms were assessed with Arabic version of Pediatric Sleep Questionnaire (PSQ). Overweight/obesity was evaluated using body mass index (BMI) and their association with SDB was tested using a regression analysis model.
Overall, 23% of children were at high risk of SDB. Prevalence of habitual snoring was 15.9% and sleep apnea 4%. Boys were at higher risk of SDB than girls (
= 0.026), while age had no effect (
= 0.254). buy Pracinostat High-risk SDB had a strong association with sleep symptoms compared to low-risk SDB (
< 0.05). Sleep-disordered breathing increased significantly in overweight and obese children (
= 0.017 and
< 0.001, respectively).
Around 23% Saudi schoolchildren are at risk of SDB. Related symptoms were strongly associated with high risk of SDB. Overweight and obesity had a strong and progressive association with SDB.
The results will help in identifying children at high risk of developing SDB and plan for early intervention to avoid the progression of SDB later in life.
