Abstract:
Abstract Strawberries have many benefits, where the malic acid contained in strawberries acts as a substance that will erode and remove several stains on the surface of teeth, including cleaning extrinsic stains. Gel preparations are widely used in medicines, cosmetics and food products, including toothpaste and teeth whitening agents. The purpose of this study was to determine the effectiveness of strawberry gel with a concentration of 83% and 75% in cleaning teeth with extrinsic stain on academic member of the Health Polytechnic Jakarta I.

Abstract:
Extrinsic stain resides in the dental pellicle and can be caused by introduction of chromogenic materials or therapeutic agents into the oral cavity. In contrast, intrinsic tooth stain is found within the tooth structure and can be caused by a variety of agents, including hematological and developmental abnormalities and drugs such as tetracycline. The mechanisms of extrinsic stain formation differ with respect to the causative agent. For example, stain induced by chlorhexidine (CH) can be explained by an increased rate in the non-enzymatic browning reactions occurring at the pellicle surface,

Discoloration of teeth can be caused by stains on the surface of the teeth or due to changes in tooth material. Tooth stain can be extrinsic, intrinsic, or age-related. Tooth whitening (bleaching) can be done in the office and at home. Strawberry is a fruit with many benefits, one of which is whitening teeth. The content of malic acid and ellagic acid in strawberries has the effect of tooth whitening.

Extrinsic staining of teeth is a common aesthetic problem for which toothpaste manufacturers strive to produce effective products to chemically and/or physically control the problem. Clinical studies proving efficacy are rare and reliance on tests in vitro are more common.

The first model utilised immobilised hydroxyapatite (RA) with tea as the chromogen. Using residual tea optical density to assess extrinsic staining proved unreliable. Tea ex

Conventional sensors are becoming obsolete in sensing for today's multistory buildings because they don't monitor the structural health of the guide rails. This sensing task falls into the fiber sensing niche market because of a fiber sensor's ability to be multiplexed.

The nature of this representation has been the subject of much debate (see Stein 1992, for discussion). The traditional view, strongly supported by subjective experience, is that we construct a single spatial map of the world in which objects and actions are represented in a unitary fra
