The crown of the tooth is covered by<u> the enamel</u>, the hardest substance in the body.

The hardest material in the human body is dental enamel, or the hard tissue that covers the outside of the tooth crown.

It is more mineralized and durable than bone and the most heavily mineralized bodily tissue.

Calcium phosphate, a hard mineral, makes up the majority of it.

Dentin is the layer that lies behind your enamel. It is created from mineral-secreting live cells. The pulp, the primary living component of the tooth, is located underneath the dentin.

Dental crowns are caps that are affixed to broken teeth.

When fillings are ineffective, crowns are utilized to preserve, cover, and restore the contour of your teeth.

Metals, porcelain, resin, and ceramics can all be used to create dental crowns.

Desafortunadamente, olvidaste anexar las imágenes para que las podamos ver. Sin embargo, con deseos de ayudarte, te podemos comentar lo siguiente basándonos en nuestro conocimiento sobre las chinampas.

> Los Aztecas fueron un gran imperio durante la época llamada Mesoamérica.

> Mesoamérica abarcaba las regiones del centro-sur de México y parte de Centro América.

> La capital del imperio Azteca fue Tenochtitlán.

> Tenochtitlán fue construida sobre un lago, el Lago de Texcoco.

> Ese región hoy en día es el centro de la Ciudad de México.

> Los Aztecas fueron excelentes ingenieros y construyeron modernos canales de agua por donde transitaban las balsas y se transportaban los Aztecas y sus productos.

> Sobre ese lago construyeron las chinampas, que eran montículos de lodo en donde los Aztecas construían sus casas y también cosechaban sus productos.

> Esas chinampas sirvieron para que los Aztecas desarrollaran avanzadas técnicas de agricultura y cosecharan semillas, verduras, plantas y flores que vendían en el mercado de Tlatelolco, al norte de Tenochtitlán.

> Los principales productos que cosechaban eran jitomates, cacao, chile, maíz y frijol.

Podemos concluir que los Aztecas fueron una brillante y moderna civilización, ya que mientras en Europa se vivían los años obscuros de la Edad Media, en Mesoamérica, los Aztecas ya construían impresionantes edificios como sus pirámides, canales de agua para transportarse, y sistemas de drenaje.
