Dental and Oral Biology

In Funaria, 32 peristomial teeth are present. It consists of two sets of long, conical teeth, one within the other. There are 16 teeth in each set. It follows hygroscopic path where moisture is absorbed or attracted from air.

Alimentary canal is also called as digestive tract. It starts in the mouth followed by buccal cavity and ends at the anus. The digestion starts in the anterior cavity called buccal cavity. Teeth are embedded in a socket of mandible (lower jaw) and maxilla (upper jaw). These sockets are called as tooth sockets. Human shows both diphyodont and monophyodont types of dentition. In diphyodont dentition, there are 2 sets of teeth, namely deciduous and permanent set. In monophyodont dentition, there is only 1 set of teeth. In humans, molar teeth show monophyodont dentition and rest teeth show diphyodont dentition. Pharynx is part of both digestive and respiratory system. Pharynx opens into oesophagus in digestive system and larynx in respiratory system. 

The following are true regarding uses of silver.
Silver amalgam is used in filling teeth.
Silver leaves are used in Ayurvedic and Yunani medicines.
Silver is used in silver plating.
It is used in the preparation of silver salts used in silvering of mirrors, photography and medicine.

The apical portion of the capsule is specialised to regulate spore discharge. It matures into operculum and peristome at maturity, the operculum falls exposing the underlying peristome, which surrounds the mouth of the dehiscent capsule.

The peristome in Funaria consists of two rings of 16 teeth each, totaling 32 teeth.

The peristome of Funaria consists of two concentric rings, each containing 16 teeth, for a total of 32 teeth.

Peristome (exposed) plays an important role in the dispersal of spores. The peristome teeth by their hygroscopic movements help in the discharge of the spores. The inner peristome simply functions as a sieve. The spores are liberated in the dry weather and are carried out by air.

The peristome, which lies immediately below the operculum consists of two sets of long, conical teeth, one within the other. The teeth of both the sets are on the same radii and thus opposite to each other. The tapering distal ends of the teeth of the outer set converge towards each other and are united terminally in a small central disc of tissue. The peristomial teeth are sculptured structures, that close the opening of the spore sac. They are attached at the base of the rim or diaphragm. The outer set of the peristomial teeth are hygroscopic and respond to the changes in humidity. The presence of peristomial teeth guarding the mouth of the theca region slows the rate of spore discharge.

The hygroscopic movement performed due to imbibition of water is called as hydrochasy. E.g., movement in the peristome of moss, elators in eqisetum. 

This is a tag question. Since the main clause 'My tooth never hurts me badly' is negative due to 'never', the tag must be positive. 'Does it' is the correct form.

An adult human has a total of 12 molar teeth, with 3 molars located in each of the four quadrants of the mouth (upper left, upper right, lower left, and lower right), which includes the four wisdom teeth.

The independent variable is the factor that the researcher deliberately changes or manipulates. In this scenario, the amount of flossing is the variable being changed to see its effect on the number of cavities.

Fluoride is a mineral that helps prevent tooth decay by strengthening the tooth enamel. In many regions, it is added to public drinking water supplies as a highly effective public health measure.

Tooth decay is directly linked to the frequent consumption of free sugars, which belong to the simple carbohydrate group. Bacteria in the mouth feed on these sugars and produce acids that attack and dissolve tooth enamel over time.
