Abstract

Hydroxyapatite (HA) has gained increasing attention as a biomimetic active ingredient in toothpaste due to its structural similarity to dental enamel and dentin, especially amid concerns over excessive fluoride exposure. This review discusses the role of HA in caries prevention and enamel remineralization, covering its antibacterial activity, physicochemical properties, synthesis strategies, and toothpaste applications. Evidence from in vitro, in situ, and clinical studies demonstrates that HA particularly in nano and ion-substituted forms effectively promotes enamel remineralization, enhances acid resistance, reduces dentin hypersensitivity, and exhibits antibacterial activity comparable or superior to fluoride toothpaste. However, challenges remain regarding nanoparticle stability, formulation consistency, and limited long-term clinical data. For HA to replace fluoride, it should be engineered as a reactive, well-dispersed nano-apatite (≤100 nm) with moderate-to-high crystallinity (~69–75%), stoichiometric Ca/P ratio of 1.67, and appropriate ionic substitution. Overall, HA represents a safe, biocompatible, and promising material for advanced toothpaste formulations.

Abstract

Biobriquettes serve as a renewable energy alternative with the potential to replace conventional charcoal while producing lower emissions. This study aimed to evaluate the effects of varying the ratio of raw material mixtures and the concentration of binder made from cassava starch on the quality of biobriquettes produced from candlenut shells (Aleurites moluccana) and empty palm oil fruit bunches (Elaeis guineensis jack). The selection of these raw materials was based on their abundant availability in Indonesia and their high lignocellulosic content. The biobriquettes were produced through a carbonization process, in which the candlenut shells were heated at 350°C for 30 minutes, while the palm oil empty fruit bunches were carbonized at 300°C for the same duration. The study applied variations in the composition ratios of candlenut shells to empty fruit bunches (100:0, 80:20, 60:40, 40:60, 20:80, and 0:100), as well as binder concentrations of 10%, 20%, and 30% (w/w) using cassava starch. The resulting biobriquettes were tested according to the Indonesian National Standard SNI 01-6235-2000 through proximate and physical analyses. The findings indicated that the variation.
