Wright's Classification of Child Behavior
-
Hysterical/Uncontrolled
- Description: This behavior is often seen in preschool children during their first dental visit. These children may exhibit temper tantrums, crying, and an inability to control their emotions. Their reactions can be intense and overwhelming, making it challenging for dental professionals to proceed with treatment.
-
Defiant/Obstinate
- Description: Children displaying defiant behavior may refuse to cooperate or follow instructions. They may argue or resist the dental team's efforts, making it difficult to conduct examinations or procedures.
-
Timid/Shy
- Description: Timid or shy children may be hesitant to engage with the dental team. They might avoid eye contact, speak softly, or cling to their parents. This behavior can stem from anxiety or fear of the unfamiliar dental environment.
-
Stoic
- Description: Stoic children may not outwardly express their feelings, even in uncomfortable situations. This behavior can be seen in spoiled or stubborn children, where their crying may be characterized by a "siren-like" quality. They may appear calm but are internally distressed.
-
Overprotective Child
- Description: These children may exhibit clinginess or anxiety, often due to overprotective parenting. They may be overly reliant on their parents for comfort and reassurance, which can complicate the dental visit.
-
Physically Abused Child
- Description: Children who have experienced physical abuse may display heightened anxiety, fear, or aggression in the dental setting. Their behavior may be unpredictable, and they may react strongly to perceived threats.
-
Whining Type
- Description: Whining children may express discomfort or displeasure through persistent complaints or whining. This behavior can be a way to seek attention or express anxiety about the dental visit.
-
Complaining Type
- Description: Similar to whining, complaining children vocalize their discomfort or dissatisfaction. They may frequently express concerns about the procedure or the dental environment.
-
Tense Cooperative
- Description: These children are on the borderline between positive and negative behavior. They may show some willingness to cooperate but are visibly tense or anxious. Their cooperation may be conditional, and they may require additional reassurance and support.
Leeway Space
Leeway space refers to the size differential between the primary posterior teeth (which include the primary canines, first molars, and second molars) and their permanent successors, specifically the permanent canines and first and second premolars. This space is significant in orthodontics and pediatric dentistry because it plays a crucial role in accommodating the permanent dentition as the primary teeth exfoliate.
Size Differential
Typically, the combined width of the primary posterior teeth is greater than
that of the permanent successors. For instance, the sum of the widths of the
primary canine, first molar, and second molar is larger than the combined widths
of the permanent canine and the first and second premolars. This inherent size
difference creates a natural space when the primary teeth are lost.
Measurement of Leeway Space
On average, the leeway space provides approximately:
- 3.1 mm of space per side in the mandibular arch (lower jaw)
- 1.3 mm of space per side in the maxillary arch (upper jaw)
This space can be crucial for alleviating crowding in the dental arch, particularly in cases where there is insufficient space for the permanent teeth to erupt properly.
Clinical Implications
When primary teeth fall out, the leeway space can be utilized to help relieve
crowding. If this space is not preserved, the permanent first molars tend to
drift forward into the available space, effectively closing the leeway space.
This forward drift can lead to misalignment and crowding of the permanent teeth,
potentially necessitating orthodontic intervention later on.
Management of Leeway Space
To maintain the leeway space, dental professionals may employ various
strategies, including:
- Space maintainers: These are devices used to hold the space open after the loss of primary teeth, preventing adjacent teeth from drifting into the space.
- Monitoring eruption patterns: Regular dental check-ups can help track the eruption of permanent teeth and the status of leeway space, allowing for timely interventions if crowding begins to develop.
