Radiation combined injury, a life-threatening condition, has higher mortality than simple radiation injury. The aim of the present study was to analyze the efficiency of Aloe vera and silver nanoparticles in improving the healing of ulcerated oral mucosa after irradiation. Thirty male Albino mice were divided into five groups: control, radiation, Aloe vera (AV), silver nanoparticles (NS), and AV+NS. The mice were exposed to whole body 6Gy gamma-radiation. After one hour, 20% acetic acid was injected into the submucosal layer of the lower lip for ulcer induction. The animals received topical treatment with the assigned substances for 5 days. Lip specimens were subjected to hematoxylin and eosin and anti alpha-smooth muscle actin immunohistochemical staining. Results demonstrated occurance of ulcer three days post irradiation in all groups except in the AV+NS group where only epithelial detachment was developed. After seven days, data revealed persistent ulcer in radiation group, and almost normal epithelium in the AV+NS group. A significant reduction of epithelial thickness was detected in all groups at the third day as compared to control. At the seventh day, only the AV+NS group restored the epithelial thickness. Area percent of alpha-smooth muscle actin expression was significantly decreased in radiation group at the third day followed by significant increase at the seventh day. However, all treatment groups showed significant increase in alpha-smooth muscle actin at the third day, which decreased to normal level at the seventh day. Our study demonstrated the efficiency of Aloe vera and silver nanoparticles in enhancing ulcer healing after irradiation.

Kulzer launches Ivory® ReLeafTM, dentistry’s best hands-free suction solution



South Bend, IN/2.9.2018. Kulzer announced today that it has launched its time-saving, patient-friendly, high volume Ivory ReLeaf hands-free HVE suction device.
Ivory ReLeaf assists with evacuation, retraction and maintaining a dry field during a wide array of dental and hygiene procedures. Unlike saliva ejectors, Ivory ReLeaf is not only a hands-free suction device, but a high volume suction device. It works in all four quadrants with ergonomic comfort and full view of oral cavity without the need to be moved around. This can save up to 15 minutes of time per patient, which can translate into hundreds of dollars in increased production throughout the day.
“The ingenious aspect of Ivory ReLeaf’s design is that its disposable leaves use the cheek and vestibule area for support, rather than relying on the shape of the arch or the orientation of the teeth,” said Lesley Melvin, Kulzer’s Director, Marketing & Product Management. “This provides 280 degrees of suction around the leaf to make time-saving uninterrupted suction throughout the oral cavity possible.” Ivory ReLeaf further contributes to practice efficiency by conveniently connecting to existing dental vacuum systems in less than 60 seconds.
Ivory ReLeaf is exceptionally patient-friendly. Patients are less likely to feel claustrophobic since the device does not obstruct the airway, and because Ivory ReLeaf does not reach the soft pallet, gag reflexes are rarely an issue. In addition, its universal mouthpiece, or “leaf,” is made of a custom blend of latex and BPA-free polymer that is both soft and comfortable. And because Ivory ReLeaf allows patients to move their heads left and right and up and down, they can communicate on a two-way basis with the clinician during the treatment.
According to Ms. Melvin, Ivory ReLeaf also provides peace of mind to patients and clinicians alike. According to the Center for Disease Control, when patients close their lips around low- volume saliva ejectors, backflow can occur when the pressure in the patient’s mouth is less than

that in the evacuator. “This backflow, which can include previous patients’ waste material, colonized biofilm from the tubing, and chemicals from flushing the line, is simply not possible with Ivory ReLeaf,” said Ms. Melvin.
