Some shape, form or number altering conditions involving the jaws, dentition, and teeth can be familial or ___?
Developmental disorder or developmental anomaly
This is a failure or disturbance that occurs during developmental processes that results in a lack, excess or deformity of a body part.
This is present at birth and can be either inherited or developmental. Most causes of this are unknown.
This is limited tongue movement secondary to improper attachment to the floor of the mouth
Short lingual frenum is corrected with surgical removal of a portion of a lingual frenum
How is ankyloglossia fixed?
Commissural lip pits, or can also be congenital lip pits
This is a developmental anomaly that forms at the corner of the mouth.
This is a developmental abnormality in whihc thyroid tissue is present in the base of the tongue between the circumvallate papillae and the epiglottis
ectopic lingual thyroid nodule
The failure of thyroid tissue to occur in its normal position is known as ___?
Due to location & size this can cause difficulty swallowing and may need to be removed.
This is an abnormal sax or cavity lined by epithelium and enclosed in a connective tissue capsule
Radicular or residual cyst
This type if cyst remains after extraction of a tooth & would not be referred right away since it may go away on its own.
can be seen on any tooth but is more common in mixed dentition and will normally resolve on its own.
This type of cyst develops in place of a tooth and is most commonly associated with 3rd molars.
This is commonly seen in the 3rd molar area, comes from remnants of the dental lamina & may be aggressive in growth
calcifying ondontogenic cyst
This uncommon type of cyst can occur at any age and once removed usually wont return.
nonaggressive, uncommon lesion that appears to arise from remnants of ondontogenic epithelium either within bone or soft tissues.
Calcifying ondontogenic cysts
Lateral periodontal cyst
This develops alongside the tooth and is usually seen in mandibular canines and in the premolar region.
This occurs in the mandibular region of canines and premolars but is found on the soft tissue
nasopalatine canal cyst
This cyst is located within the nasopalatine canal or incisive papilla. This cyst may appear heart shaped radiographically between the maxillary incisors
This cyst is found between root of maxillary lateral incisor and canine and is pear shaped
Median Mandibular Cyst
The origin of this rare cyst in unclear, it is found in the midline of mandible
This cyst is a swelling in the mucolabial fold of the maxillary canine area and the floor of the nose
This cyst resembles acne, is moveable, normally located on the floor of the mouth or in the cheek area. Sometimes it is connected to a pore and is filled with a cheesy material.
This cyst is present at birth, is rarely found in the oral cavity but if it is it is on the floor of the mouth
Thyroglossal Tract Cyst
This is an enlargement at the midline of the neck caused by a duct that descends from the tongue
Static Bone Cyst
This psuedocyst is found radiographically in the posterior region of the mandible inferior to the mandibular canal & may go away on its own.
Simple Bone Cyst
This psuedocyst is identified by scalloping around the roots and may go away on its own.
Aneurysmal Bone Cyst
This is a blood filled space that looks like a honeycomb or soap bubble & is usually due to trauma
This is when a single tooth germ attempts to divide and results in incomplete formation of two teeth
This is when an accessory enamel cusp is found on the occlusal surfaces of premolars & is usually seen in mongoloid patients
1. Febrile illness
2. Vitamin deficiency
3. Local infection or trauma
4. Flouride ingestion
5. Congenital syphillis
6. Birth injury, premature birth,
7. Idiopathic factors (unknown)
What are some causes of incomplete formation of enamel?
This are disturbances that occur during the maturation of the enamel matrix (white spots)
Endogenous Staining of the teeth
This is caused by systemically circulating substances (like tetracycline) that are in the body during tooth development.
