11 - Common Clinical Growth and Development Issues Flashcards
local causes of clinical growth and development issues
- Ankylosis
- Impaction
- Supernumerary tooth
- Trauma
systemic conditions causing clinical growth and development issues
- Low birthweight/premature
- Down syndrome
- Apert syndrome
- Chondoectodermal dysplasia
- Cliedocranial dysplasia
- Albright’s hereditary osteodystrophy
- Osteogenesis imperfecta
- Achondroplasia
- Gardner syndrome
- Hypothyroidism
- Hypopituitarism
what causes primary failure to erupt
Malfunction of eruption mechanism with non-ankylosed teeth
Failure of affected tooth to move through eruption path cleared for it
Teeth may partially erupt yet remain submerged or not erupt at all
Abnormal or complete lack of response to orthodontic forces
treatment of primary teeth failing to erupt
varies but often extraction and prosthodontic replacement
Successful treatment depends on multi-specialty collaboration: Pediatric/General dentist, Orthodontist, OMFS, Prosthodontist, etc.
what are common clinical growth and devlopment issues that lead to premature exfoliation of primary teeth
local causes that lead to accelerated permanent tooth eruption
early loss of primary teeth
systemic causes that lead to accelerated permanent tooth eruption
- Chondoectodermal dysplasia
- Hemifacial hypertrophy
- Osteogenesis imperfecta
- Hyperthyroidism
- Precocious puberty
- Sturge-Weber syndrome
what is a group of conditions where there is abnormal development of the skin, hair, nails, teeth or sweat glands
ectodermal dysplasia
any tissues that are embryologically derived from ___ may potentially be affected in ectodermal dysplasia
ectoderm
T/F: many different types/subcategories of ectodermal dysplasia is each caused by a specific genetic mutation
TRUE
what individuals may exhibit thin sparse hair, poor vision, and intolerance to heat due to lack of functional sweat glands
pt with ectodermal dysplasia
describe cleft lip
lip does not completely form
what is upper lip derived from
upper lift is derived from the median nasal process and maxillary process
when do median nasal process and maxillary process merge (lack of merge results in cleft lip)
5 weeks gestation
what is cleft palate
roof of mouth does not completely form leaving an opening that can extend into nasal cavity
what is the palate derived from
median nasal process and palatal shelves of maxillary process
when do median nasal process and palatal shelves of maxillary process merge
8-12 weeks gestation
prevalence of:
- cleft lip
- cleft palate
- clef lip with or without cleft palate
Cleft lip: 1 in 700 in US
Cleft palate: 1 in 1,000 in US
Cleft lip with or without cleft palate: 1 in 300-500 in US
what are common dental findings for patients with cleft lip and/or palate
Congenitally missing teeth
Supernumerary teeth
Malformed teeth
Transposed teeth or teeth not in the correct position
Rotated teeth
Tipped teeth
Delayed eruption
Premature eruption
Enamel hypoplasia
Dentin defects
Class III malocclusions common (midface deficiency)
Narrow maxillary arch
Anterior or posterior crossbite
what are complications patients with cleft lip and/or palate have
Higher risk for caries due to presence obturators, retainers, palatal expanders, and other orthodontic devices
Anatomic variation may cause difficulty with oral clearance and oral hygiene
Patients likely to undergo multiple surgeries at young age - resultant scar tissue may restrict oral opening and cause difficulty with oral hygiene procedures and dental restorative care
Patients likely to undergo multiple surgeries at a young age and may have learned aversion to healthcare providers
who is part of treatment team for cleft lip and/or palate
Most successful treatment is from multidisciplinary healthcare team: Pediatrician, Geneticist, Plastic Surgeon, Oral Surgeon, Pediatric/General Dentist, Orthodontist, Audiologist, Speech Pathologist, and others
who serves as dental home for patients and help to coordinate oral health care
pediatric/general dentist
prevention is important in what patients
patients with congenitally missing teeth
because arch length and alveolar bone preservation critically important
surgical management of cleft lip and/or palate at:
0-3 months
Pre-surgical infant orthopedics is used to narrow the cleft by reducing the gap in alveolar segments and lip (ex: Nasoalveolar molding, lip taping)
