Histological Evaluation the effectiveness of Aloe Vera oral gel Application on Gingiva Subjected to Dental Light –emitting Diodes
Keywords:Aloe Vera, gingiva, Light –emitting Diodes, rabbit
Background: Aloe Vera (AV) is a medical plant used in dentistry with multiple uses proved as antiseptic, antifungal, antiviral and anti-inflammatory and very good in building the immune system with a natural compound that has no side effect, for that reason we use it as protective layer from the heat that generated from LED light cure during the filling or cementation procedure or others. Materials and method: Thirty-five male New Zealand rabbits of weight 1.5 –2kg were used in this study; they were divided into three groups. First group (5 rabbits) the gingiva of upper incisors is not exposed to dental LED light cure (control group), Second group (15 rabbits) which the cervical gingiva of upper incisors which is separated from light source by double transparent celluloid strips, cervical gingiva is exposed to LED curing light 6 seconds three times with 20 seconds interval. Third group (15 rabbits) same as 2nd group but gingiva covered by Aloe Vera oral gel. Animals’ scarifications were done at (0 day) immediately after exposure to curing light ,3 days,7 days healing intervals. Routine processing and sectioning technique was performed for histological evaluation. Results: Histological findings indicated variation in epithelial thickness, irregularity in basal cells layer and number of blood vessels of 2nd & 3rd experimental groups from 1st control group. The highest mean values of all measured Histomorphometrical parameters were observed in 2nd group 3 days after dental LED light cure exposure. Conclusion: Aloe Vera oral gel may be used on gingiva as a protective layer to decrease side effects of LED light cure on gingiva.
