Investigators from the NIH performed a longitudinal, prospective, natural history study looking at patients with COL6-related dystrophies (COL6-RDs) and LAMA2-related dystrophies (LAMA2-RDs), the two most common congenital muscular dystrophies (CMDs).Investigators from Karolinska Institute in Stockholm, Sweden report on their findings comparing quality of life (QoL) measures in both pediatric-onset multiple sclerosis (POMS) and adult-onset multiple sclerosis (AOM).Researchers from the Autism Sequencing Consortium (ASC) led by Joseph Buxbaum at the Icahn School of Medicine at Mount Sinai report the largest exome sequencing study in autism spectrum disorder (ASD) to date.Investigators from Europe and the USA, representing the STRIDE Registry and Cooperative International Neuromuscular Research Group (CINRG) Duchenne Natural History Study (DNHS), examined the effectiveness of ataluren and standard of care in the Registry versus stand of care alone in the CINRG DNHS.
Early childhood caries is a multifactorial disease. Saliva plays an important role in initiation and protection against caries, and its composition is greatly affected by nutritional status. This study was conducted to determine the impact of salivary lactoperoxidase and histatin-5 on the severity of ECC in relation to nutritional status.

The sample consisted of 120 children aged 5years, classified into eight groups mild ECC in underweight children, mild ECC in normalweight children, moderate ECC in underweight children, moderate in ECC normal weight children, severe ECC in underweight children, severe ECC in normalweight, caries-free (control) underweight children and caries-free normalweight children. Each group consisted of 15 children. Stimulated saliva was collected. Salivary lactoperoxidase was analysed using Human LPO/ Lactoperoxidase ELISA Kit (CLIA)-LS-F29892, and salivary histatin-5 was analysed using Human Histatin-5 ELISA Kit MBS705083_48T.

Lactoperoxidase and histatin-5 concentrations were ns. There is interaction between these two parameters and ECC severity and nutrition.
Salivary lactoperoxidase and histatin-5 may be affected by nutritional status, and these two parameters may play an important role in caries prevention at high concentrations. There is interaction between these two parameters and ECC severity and nutrition.
Identification of the mandibular canal (MC) is essential before any lower jaw surgical procedures. XL184 in vivo Understanding the anatomical variations of the MC is essential for preventing postoperative complications.

We assessed the observer agreement for identifying the MC in cone-beam computed tomography (CBCT) images and to study the effect of changing the voxel size on such agreements.

We obtained images of mandibles from ten dry skulls using a water phantom with two voxels 0.18 and 0.3 mm. The identification of the MC was made in five sites bilaterally in each mandible by two examiners.

A total of 82 sites were included. Differences in measurements between images obtained with each scanning protocol and the reference images were calculated using descriptive statistics. There was an agreement between the two examiners in identifying the MC in CBCT images. No significant differences were found for identifying the MC when the voxel sizes were changed. There was a strong correlation coefficient between the two examiners for both voxel sizes (p < 0.001).

This study showed that voxel size, in the range from 0.18 to 0.3 mm, has no direct effect on the identification of the MC.

Knowledge and evaluation of the blood supply within the maxillary sinus before sinus augmentation are vital to avoid surgical complications. The lateral maxilla is supplied by branches of the posterior superior alveolar artery and infraorbital artery forming intraosseous anastomoses (IA) within the bony lateral antral wall. This study was undertaken to (i) measure mean diameter of IA and its distance from the alveolar ridge within dentate and posteriorly edentulous subjects and, (ii) qualitatively display the relationship of IA throughout its course within the lateral maxillary sinus in cone beam computed tomography (CBCT).

Maxillary CBCT images of two-hundred-and-fifty-seven consecutive patients (163 men, 94 women, mean age 42years) were analyzed. Samples were later divided into dentate (n=142) and posteriorly edentulous (n=115) jaws. Using both alveolar ridge and tooth location as reference points, the distance and diameter of IA were assessed.

The IA was seen in 63.7% of all sinuses with 68.2% in denures contain neurovascular bundles with diameters that may be large enough to cause clinically substantial complications, a thorough pre-surgical planning is therefore highly advisable.
This study aimed to assess and compare the effectiveness of three different remineralizing agents (Tricalcium phosphate paste, Fluoride varnish, and Nano-hydroxyapatite gel) using the DIAGNOdent device.

The present clinical study was carried out on 90 initial carious lesions detected by ICDAS caries diagnostic criteria and then take the baseline record by DIAGNOdent device. The selected initial carious lesions were randomly classified into three groups according to treatment modalities (30 lesions in each group) according to remineralizing agents group A (TCP), group B (fluoride varnish) and group C (nano-hydroxyapatite gel). The remineralizing agents were applied for four minutes once weekly for four weeks. At the fifth week, the DIAGNOdent scores of initial carious lesions were recorded to evaluate the effect of remineralizing agents. A paired t-test was used to compare between baseline date and follow up of DIAGNOdent scores. A one-way ANOVA test was used to compare DIAGNOdent scores among the three groups. Post- Hoc Tukey test was used to determine the significant difference between every two groups.

There were statistically significant differences among the three groups at follow up (p = 0.001). Within each group, there was a significant difference between baseline and follow up scores (p = 0.000 for the three groups). Multiple comparisons between every two groups showed a highly statistically significant difference at follow up records between nano-hydroxyapatite versus TCP and fluoride varnish on pit and fissure caries (p = 0.039 and p = 0.007 respectively) and the nano-hydroxyapatite was the best of them.

The present study concluded that the three remineralizing agents were effective in the treatment of initial carious lesion and the most effective remineralizing agent was nano-hydroxyapatite.
