Evaluation of the Antiplaque and Antibacterial Effect of Aloe Vera, Chlorhexidine and Fluoride Containing Toothpastes “In-vitro Study”

Abstract

Dental plaque plays a major role in the etiology of dental caries.4 It has been identified that a diverse microflora is found in dental plaque biofilms. Therefore, “The specific plaque hypothesis” was put forward as a major advance.5 This hypothesis proposed that the disease is actively caused by only a few of the many species found in dental plaque biofilms. Thus, we can control caries disease by targeting preventative measures and interventions against these ‘‘specific’’ organism 20. Over the years, various synthetic chemical agents have been evaluated for their antimicrobial effect in oral cavity. The chlorhexidine remains the benchmark control in the removal of plaque accumulated over enamel surface 8. However, it cannot be used for a long period of time due to its many side-effects like altered taste sensation and staining of tongue 9. Accordingly; patients are preferring to shift away from modern medicines, and they prefer using herbal preparations like Terminalia chebula, Aloe Vera, Azadirachta indica, piper betle, Ocimum sanctum11. Aloe Vera extract has been considered as one of the natural oral hygiene aids to reduce plaque formation and accumulation. Aloe Vera was used for many and different treatments like burns, hair loss, skin infections, haemorrhoids, sinusitis, and gastrointestinal pain 156. It is also a wound healer for bruises, insec
