Facial Development
Mandibular arches (1) divide into the mandibular and maxillary processes in this week.
What is the 3rd week of development?
6th week of embryonic stage, tooth development begins with this primary structure
What is dental lamina?
Disturbance in the dental lamina causes this (think of total # of teeth)
What is anodontia and supernumerary teeth?
Cells found in this rapidly divide initiating root formation
What is Hertwig's root sheath?
What cell has a primary role in dentin production
What is an odontoblast?
This arch forms the facial muscles.
What is the hyoid arch?
enamel organ originates from
What is ectoderm?
Macro/microdontia and peg laterals results from the budding off of the dental lamina around the 8th week in this stage
What is the bud stage?
The result of the root sheath cells not separating from the dentin and morphing into ameloblasts
What is an enamel pearl?
Forms when teeth reach occlusion, decreasing the size of the pulp chamber and its canals
What is secondary dentin?
Medial and maxillary processes begin to fill in closing a groove, is complete by this week mitigating a cleft lip
What is the 7th week of development?
dental papilla, dentin and pulp originates from
What is mesoderm?
disturbance in this produces Dens in dente, germination, fusion, primordial cyst, tubercles
What is the stellate reticulum or the cap stage?
epithelial rest cells also known as
What is epithelial rests of Malassez?
Usually occurs as a result of occlusal trauma
What is tertiary dentin?
Failure of the connective tissue to fill in the groove between the medial nasal and maxillary processes
What is a cleft lip?
PDL, cementum and some of alveolar bone originates from this early cellular formation
What is the dental follicle?
Disturbance of this layer produces enamel dysplasia
What is stratum intermedium?
These cells may activate to become periodontal cysts
What is epithelial rest cells?
Dentinal response to localized trauma
What is reparative dentin?
Between the 7th and 11th week, failure to fuse of what anatomy produces a cleft palate
What is the maxillary processes and the primary palate?
The stage when outer enamel epithelium and inner enamel epithelium are developed.
What is the cap stage?
Disturbance in the enamel organ happens in this tooth developmental stage
What is the bell stage?
a defect that can cause difficulty in endodontic treatment
What is an accessory canal?
inorganic component of dentin, gives it its hardness
What is hydroxyapatite?
