Abstract

Visuospatial processing is one of the important aspects of everyday life, whether it is to travel or to recognize the location of objects around. Visuospatial processing can be improved in various way, one of which is by using repetition. WorldVenture app was created to help its users improve their visuospatial capability by remembering landmarks in the city where they live. WorldVenture was created using flutter framework with five steps, namely literature study, data and information collection, application designing, testing, and evaluation. This app will have three main features: Flashcard, Quiz, and Notes. WorldVenture testing result, using questionnaires, showed 64,5% people out of 30 respondents rated WorldVenture excellent for improving visuospatial capabilities and as many as 35.5% of respondents rated it good.

Abstract

Background: Bone regeneration is a process to repair bone structure but has limited reparative capacity because the bone resorption process occurs in line with the regeneration process. Bone graft application is required to minimize resorption and guide bone regeneration, including in alveolar bone after tooth extraction. Snakehead fish scales are known to contain hydroxyapatite components as an alternative bone graft material to increase fibroblasts in tooth sockets. Purpose: To determine the effect of sneakhead fish scale hydroxyapatite as an alternative bone graft material on the number of Wistar rat alveolar bone fibroblasts after tooth extraction. Methods: This study was in vivo laboratory experimental study, single blind, with a post test only control group design. The samples used were Wistar rat which were divided into 4 groups after tooth extraction, the treatment group (HAp) was given hydroxyapatite from snakehead fish scales for 7 and 14 days and the control group was given distilled water for 7 and 14 days. Euthanasia of rat was carried out on days 7 and 14, then the jaw was cut off and histopatological preparations were made. The number of fibroblast was counted and analyzed statistically. Results: The Independent T-test showed that the number of fibroblasts was higher in the treatment group than control (p-value>0,05). Conclusion: Hydroxyapatite from snakehead fish scales can significantly increase the number of fibroblasts in rat socket after tooth extraction. Keywords: bone regeneration, fibroblast, snakehead fish scale, tooth extraction, wistar rat
