What Is Active Voice?
I'll start with active voice because it's simpler.

In an active sentence, the subject is doing the action. A straightforward example is the sentence "Steve loves Amy." Steve is the subject, and he is doing the action: he loves Amy, the object of the sentence.
Another example is the title of the Marvin Gaye song “I Heard It through the Grapevine.” "I" is the subject, the one who is doing the action. "I" is hearing "it," the object of the sentence.

What Is Passive Voice?
In passive voice, the target of the action

gets promoted to the subject position. Instead of saying, "Steve loves Amy," I would say, "Amy is loved by Steve." The subject of the sentence becomes Amy, but she isn't doing anything. Rather, she is just the recipient of Steve's love. The focus of the sentence has changed from Steve to Amy.
If you wanted to make the title of the Marvin Gaye song passive, you would say “It was heard by me through the grapevine,” not such a catchy title anymore.

Filling’s material: permanent & temporary.

What is a Temporary Filling? Temporary fillings

are made of materials that are intended to last for up to one month. Zinc oxide eugenol is a material commonly used for temporary fillings. Temporary fillings are used when it is not possible or it would be detrimental to place a permanent filling. For example, if a patient has several dental cavities that require more than one appointment to fill, a dentist may restore teeth with a temporary material before placing permanent fillings. A temporary filling can also be used to soothe irritated nerves in a tooth's pulp or allow the pulp time to heal before a permanent filling is placed

What is a Permanent Filling? Permanent fillings, with proper care, can

last from years to a lifetime. The procedure for placing a permanent filling includes drilling of the tooth to remove decayed enamel and dentin before filling it with either silver amalgam, composite resin or glass ionomer.

Silver Amalgam Filling. Silver amalgam fillings are the strongest and most common type of dental filling. They are usually placed on the rear molars or on large, deep cavities. Silver amalgam is a mixture of 35% silver, 15% tin or tin and copper, a trace of zinc and 50% mercury. Silver amalgam fillings have been used since 1833, but have lost much popularity over the years due to their mercury content, tendency to expand with time and unattractive appearance.

Composite Resin Fillings. Composite resin fillings are made of a acrylic

Composite Resin Fillings. Composite resin fillings are made of a acrylic

resins and finely ground glass. They are tooth-colored so they resemble the color of surrounding teeth for a natural appearance. Composite resin is applied to teeth in several semi-liquid layers that harden in minutes. An ultraviolet light is often used to accelerate hardening. These fillings tend to last between six and 12 years. They are not as durable as silver amalgam fillings, so they should not be placed in large molar cavities that must endure a lot of chewing. Composite resins sometimes shrink while setting, thus opening up gaps that allow bacteria access to the tooth's interior.

Glass Ionomer Fillings. Glass ionomer fillings are made of acrylic resins

Glass Ionomer Fillings. Glass ionomer fillings are made of acrylic resins

and powdered glass like composite resin fillings, but are available in fewer colors. They are the weakest type of filling, so they are not used on chewing surfaces. The greatest advantage to glass ionomer fillings is their ability to release fluoride; they can continue to strengthen enamel and fight bacteria long after they have been placed.
