ABPD Pediatric Dentistry key terms

A behavior-shaping technique in which the clinician explains a procedure in child-friendly words, demonstrates it with a model or on the child, then performs it. It reduces fear by making the unknown predictable.

Gradual reinforcement of successive approximations toward a desired cooperative behavior, such as opening the mouth wider over several visits. Progress is rewarded at each step rather than only at the end.

Increasing the likelihood of cooperative behavior by following it with a rewarding consequence, such as praise, a sticker, or a token. It is most effective when delivered immediately and specifically.

Deliberate modulation of voice tone, volume, and pace to gain a child's attention and guide behavior, shifting from gentle to firm as needed. It is a mild aversive technique reserved for uncooperative behavior.

A controversial aversive behavior technique in which the clinician briefly covers the child's mouth to interrupt escalating disruptive behavior while explaining the expectation. Its use is restricted, requires consent, and is discouraged in many settings.

The use of staff, devices, or both to limit a child's movement for safe completion of care when less restrictive methods fail. It requires documented indication, informed consent, and continuous monitoring of the airway and pulse.

The process of explaining the rationale, risks, benefits, and alternatives of a planned behavior technique to the legal guardian and obtaining documented permission before use. It is required for aversive and restrictive techniques.

Systematically introducing feared stimuli at low intensity and gradually increasing exposure while the child stays calm, for example letting a child hold and then feel a mirror before an exam.

Redirecting a child's attention away from a stressful procedure using age-appropriate stimuli such as music, video, or counting, delivered as a reward for cooperative behavior rather than as a bribe.

A reinforcement system in which the child earns tokens for specified cooperative behaviors and exchanges accumulated tokens for a chosen reward. It makes expected behaviors explicit and provides immediate feedback.

A four-point scale classifying a child's cooperation during treatment, from definitely negative through definitely positive. It is a descriptive clinical rating, not a measure of anxiety or a predictor of future behavior.

An observational rating of a child's anxiety and behavior during dental visits, scored from relaxed through very distressed. It is used in research and clinical assessment to track change over time.

Inhalation of nitrous oxide with oxygen to reduce anxiety and raise the pain threshold while the child stays conscious and responsive. Effects reverse quickly with oxygen, and it is not a substitute for behavior guidance.

Non-pharmacologic techniques such as communication, tell-show-do, and positive reinforcement that form the foundation of pediatric behavior management before any advanced or pharmacologic adjunct is considered.

Caries affecting primary teeth in children under six years, often with a distinctive pattern on maxillary incisors and smooth surfaces. Frequent sugar exposure and inadequate fluoride are major contributors.

A structured evaluation of factors that predict future caries, including diet, fluoride exposure, plaque, salivary flow, and prior lesions. Results guide recall intervals and preventive and restorative decisions.

A concentrated topical fluoride preparation painted onto tooth surfaces to prevent and arrest caries. It sets on contact with saliva and is applied at intervals based on individual caries risk.

A topical agent combining silver and fluoride that arrests active caries lesions and reduces sensitivity. It blackens arrested lesions, so esthetic counseling and guardian consent are needed before use.

Placing a preformed metal crown over a primary molar with caries without local anesthesia or tooth preparation, sealing the lesion under the crown. Success depends on case selection and patient acceptance.

A preformed metal crown used to restore severely broken-down or pulpotomized primary molars. It offers durable full-coverage protection and is cemented after appropriate tooth preparation or with the Hall technique.

Removal of the coronal pulp while preserving vital radicular pulp in a primary or immature permanent tooth, followed by a medicament and seal. It is indicated when inflammation is limited to the coronal tissue.

Complete removal of coronal and radicular pulp tissue followed by cleaning, shaping, and obturation of the root canals. In primary teeth it is used when radicular pulp is irreversibly inflamed or necrotic.

An appliance that preserves arch length after premature loss of a primary tooth until the permanent successor erupts or space closure is planned. Type depends on which tooth is lost and dental development.

The typical sequence and timing of primary and permanent tooth emergence, used to judge whether a child's dental development is normal or delayed. Primary teeth usually begin erupting around six months.

A tooth present at birth, most often a mandibular incisor. If mobile it may be extracted to protect the infant's airway and nursing, otherwise it is monitored.

Local discomfort and irritability associated with primary tooth eruption, typically beginning around six months. Symptoms are usually mild; high fever or systemic illness should not be attributed to teething.

A developmental defect of systemic origin affecting one or more first permanent molars, often with incisor involvement, producing demarcated enamel opacities. Affected teeth are prone to breakdown and sensitivity.

A hereditary disorder of enamel formation affecting primary and permanent teeth, causing thin, discolored, or pitted enamel that chips easily. Management focuses on protection, sensitivity control, and restoration.

A hereditary defect of dentin formation producing opalescent, weak teeth with bulbous crowns and narrow roots. Teeth wear rapidly and may require full-coverage protection.

Complete displacement of a tooth from its socket, most often a maxillary central incisor after trauma. Prompt replantation or storage in a suitable medium strongly affects periodontal healing.

Traumatic displacement of a tooth within its socket, ranging from concussion and subluxation through extrusive, lateral, and intrusive types. Management depends on displacement direction and root development.

Injury to teeth and supporting tissues from impact, common in childhood and often involving maxillary incisors. Assessment includes fracture type, pulp status, mobility, and the need for radiographic follow-up.

Early treatment aimed at correcting or reducing developing malocclusion, such as managing crossbites or space loss. It can simplify or eliminate later comprehensive treatment.

Preventive guidance given from the first tooth or first birthday, covering feeding practices, oral hygiene, fluoride, and a dental home. It establishes habits that reduce early childhood caries risk.

A continuous, accessible source of comprehensive oral care delivered by a known clinician from infancy onward. It supports prevention, timely intervention, and a trusting relationship with the child and family.

A developmental enamel defect from excessive fluoride intake during tooth formation, appearing as white flecks to brown mottling. Severity depends on dose and timing of exposure.

A resin or glass ionomer coating placed in occlusal pits and fissures to block plaque retention and prevent caries. Retention is best when placed on fully erupted, isolated teeth.
