PEDO Flashcards
Most likely dens in dente tooth
Max Lat
_____ and_____ are the most common congenitally missing teeth in the permanent dentition after 3rd molars.;
Maxillary lateral incisors and mandibular second premolars
max canines be impacted
WHen shld first dental visit be?
Within 6 mo of the eruption of the first primary tooth
_______is indicative that the child has the manual dexterity to brush their own teeth effectively.
Tying shoelaces
This typically occurs when the child is about 7 years of age.
permanent ERUPTION SEQUENCE:
Eruption Sequence of Permanent Teeth:
Mandibular Maxillary
Central incisor 6 - 7 years 7 - 8 years
Lateral incisor 7 - 8 years 8 - 9 years
Canine 9-10 years 11 - 12 years
1st Premolar 10 - 12 years 10 - 11 years
2nd Premolar 11 - 12 years 10 - 12 years
1st Molar 6 - 7 years 6 - 7 years
2nd Molar 11 - 13 years 12 - 13 years
3rd Molar 17 - 21 years 17 - 21 years
Eruption of permanent Mand and Max 1st PM =
1st Premolar 10 - 12 years 10 - 11 years
Eruption of permanent Mand and Max Centrals =
Mand CI = 6 - 7 years
Max CI = 7 - 8 years
Eruption of permanent Mand and Max 2nd PM =
2nd Premolar 11 - 12 years 10 - 12 years
_______ is common in children due to immature oral behavior, narrow dental arches, prolonged URI, spaces between the teeth (diastema), muscle weakness, malocclusion, abnormal sucking habits, and open mouth posture due to structural abnormalities of genetic origin.
Tongue thrusting
Large tonsils and adenoids also contribute to tongue thrust swallowing.
Eruption of permanent Mand and Max Laterals =
Mand LI = 7 - 8 years
Max LI = 8 - 9 years
Eruption of permanent Mand and Max Canines =
MAND C = 9-10 years
MAX C = 11 - 12 years
Eruption of permanent Mand and Max 1st Molars =
MAND 1st Molar = 6 - 7 years
MAX 1 st Molar = 6 - 7 years
Eruption of permanent Mand and Max 2nd/3rd Molars =
MAND 2nd Molar = 11 - 13 years
MAX 2nd Molar = 12 - 13 years
MAND 3rd Molar = 17 - 21 years
MAX 3rd Molar = 17 - 21 years
Exam of 7 yo kid shows : Narrow dental arch, diastema, open mouth posture, abnormal sucking habits. What dx?
Tongue thrusting
Large tonsils and adenoids also contribute to tongue thrust swallowing.
Exam of 7 yo kid shows
- open bite
- protrusion of the maxillary incisors
- high and narrow palatal vault
- unilateral crossbite.
Dx?
Thumb (digit) sucking —-> creates an open bite and protrusion of the maxillary incisors. Digit sucking is also implicated in the creation of a high and narrow palatal vault as well as a unilateral crossbite.
______ is an enamel hypoplasia of a permanent tooth resulting from an infection of a deciduous tooth.
Turner tooth
The periapical involvement can disturb the ameloblasts of the underlying permanent tooth, creating the anomaly.
Signs of hypothyroidism in young patients may manifest as :
a delayed eruption of the teeth
malocclusion
skeletal growth retardation.
Dental practitioners may be the first to note these concerns and should refer for medical evaluation.
____ aka _____ is a developmental anomaly that results when the enamel organ invaginates into the crown of a tooth before mineralization occurs.
Dens in dente (dens invaginatus)
The calcification of primary manx centrals begins at _______.
14 weeks in utero ( same for mand CI
Crown complete : 1.5 mo (2.5 mand)
Eruption: 10 mo ( 8mo for mand)
Root completed: 1.5 yrs both
Calcification trend for primary teeth:
max = mand = Ci, 1M, Li, C, 2M
14 - CI 15 - 1M 16- LI 17 - C 18 -19 = 2M
Eruption trend for primary teeth:
mand ci, max ci, max Li, mand Li, 1M, C, 2M
8-10 mo = CI 11 - 13 mo = LI 16 mo = 1M 19 -20 mo = C 27-29 mo = 2M ~ 1.5 yrs (root complete at 3)
The calcification of primary mandibular 1st molars begins at _______.
15 wks in utero ( max = same)
Crown Completed: 5.5 mo ( 6mo for max)
Eruption: 16 mo
PERM TEETH CALC: CI Li C 1PM 2PM 1M 2MCI
CI = 4-5 yr LI = 4- 5 yr C = 6 - 7 yr 1PM = 5 - 6 yr 2PM = - 6 7 yr 1M = 30 - 36 mo 2M = 7- 8 yr

The calcification of primary mandibular second molars begins at ________________.
18 weeks in utero.
________ is characterized by vertically long pulp chambers and short roots, resulting from the failure of the proper level of horizontal invagination of Hertwig’s epithelial root sheath.
Taurodontism
