Materials and Methods: This is a laboratory experimental study using pretest and posttest on 24 Wistar rats which are divided into two groups: control group (treated with streptozotocin induction but without administration of okra fruit extract) and treatment group (treated with streptozotocin induction and oral administration of 250 mg/kg okra fruit extract once a day). Extractions of the rats' mandibular left incisors were performed using a pair of modified forceps and an elevator. The tooth sockets were then irrigated using saline solution. Four rats in each group were sacrificed on day 3 (KO1, PO1), 5 (KO2, PO2), and 7 (KO3, PO3). The socket tissues from the rats were then immunohistochemically analyzed. Data were analyzed at level significance of 0.05.
Results: The average level of TGF-β1 expression in the treatment groups was higher compared to the control group: PO1 (11.59 ± 0.58), PO2 (15.15 ± 1.07), and PO3 (18.75 ± 2.73) as compared to KO1 (5.32 ± 1.69), KO2 (8.47 ± 0.60), and KO3 (9.28 ± 1.16) with P = 0.001.
Conclusion: The administration of okra fruit extract can increase the level of TGF-β1 in wounds after tooth extraction of diabetic Wistar rats.
METHODS: A systematic search on the PubMed and Embase databases was conducted to identify eligible studies. The last search was done on April 24th, 2020. The quality of the included studies was evaluated using the Joanna Briggs Institute (JBI) Critical Appraisal tools.
RESULTS: Of the 997 articles identified, 31 articles were included in this review. Seven studies targeted students in preschools, seventeen in elementary schools, and seven in high schools. Most of these studies revealed positive outcomes. Some studies showed that the school-based oral health promotion programmes showed better OHK, OHB, OHS, and OHRQoL.
CONCLUSION: Positive results were obtained through oral health promotion programmes in schools, especially those involving children, teachers, and parents.
