Cemental caries tends to increase in older adults as gingival recession occurs, exposing the cementum to cariogenic bacteria leading to decay.

The primary dentition period refers to the first set of teeth that children have, which are eventually shed to make way for the permanent teeth. This process usually occurs from approximately 6 months to 6 years old, with completion typically around 30 months. The older term for the primary dentition is deciduous.

The mixed dentition period, also referred to as the 'transitional stage,' occurs between 6-12 years old when both primary and permanent teeth are present. It is a critical phase of dental development.

The permanent dentition period actually begins beyond 12 years of age when the shedding of the last primary tooth initiates the transition to all permanent teeth.

The question initially provided details about the eruption timing of primary maxillary teeth, but the correct answer was for the eruption timing of primary mandibular teeth. The incorrect answers provided are variations that deviate either in terms of teeth location or eruption timing to test knowledge on the subject.

The Universal Numbering System (UNS) is specifically used in the U.S for dental purposes, assigning numbers to primary (A-T) and permanent (1-32) teeth.

The correct answer explains how the INS system uses a 2-digit code to identify a tooth's position based on the quadrant and the tooth's location within that quadrant. The incorrect answers provide alternative interpretations that do not align with the actual INS coding system.

The Palmer Notation Method is actually a dental numbering system used to uniquely identify each tooth for easy reference during dental treatments.

An alveolus, in the context of dentistry, refers to a tooth supported by the bone of the tooth socket, located in the alveolar process.

Anterior teeth are the front teeth in the mouth, which include the incisors and canines. These teeth are important for biting and tearing food.

Posterior teeth refer to the teeth located towards the back of the mouth, which are premolars and molars. Incisors and canines are anterior teeth, while wisdom teeth are a type of molars. Central and lateral incisors are also anterior teeth.

The D-A-Q-T System in dentistry is a specific sequence used to describe each tooth, detailing dentition, arch, quadrant, and tooth type.

In dentistry, a cusp refers to the pointed or rounded edge on the surface of a tooth. It is important in guiding the chewing motion. Canines, premolars, and molars all have cusps that aid in their specific functions.

The Cusp of Carabelli is a fifth, non-functioning cusp found on the mesiolingual aspect of the permanent maxillary first molars or the distobuccal aspect of the primary maxillary second molars. This anatomic feature is a common variation in human dentition.
