1. Commissural Lip Pits
• Dimplelike invaginations
• Corner of the lips
• Unilateral or bilateral
• Failure of fusion of the
embryonic maxillary and
mandibular processes
Copyright © 2017 Wolters Kluwer · All Rights Reserved
2. Paramedian Lip Pits
• Congenital depressions
that occur in the
mandibular lip
• Develop when lateral sulci
of the embryonic
mandibular arch fail to
regress during the 6th
week in utero

3. Cleft Lip
• Results when the medial
nasal process fails to fuse
with lateral portions of the
maxillary process of the
first branchial
(pharyngeal) arch
• Upper lip is most
commonly affected

4. Cleft Palate
• The palate develops from
the primary and
secondary palate
• Palatal fusion is initiated
during the 8th week in
utero
• Generally completed by
the 12th week of
gestation

5. Bifid Uvula
• Minor cleft of the posterior
soft palate
• Asian and Native
American
• A submucosal palatal cleft
may occur with bifid uvula
Copyright © 2017 Wolters Kluwer · All Rights Reserved
5. Bifid Uvula (cont.)
• Develops when the
muscles of the soft palate
are clefted, but the surface
mucosa is intact
• Clefted region is notched
• Incomplete cleft
• Complete cleft

6. Congenital Epulis
• Benign, soft tissue growth
arising exclusively in
newborns from the
edentulous alveolar ridge
or palate
• Most commonly in the
anterior maxilla
Copyright © 2017 Wolters Kluwer · All Rights Reserved
7. Melanotic Neuroectodermal Tumor of
Infancy
• Rare benign tumor of
neural crest cell origin
• Rapidly growing mass in
the anterior maxilla during
the first year of life

8. Dental Lamina Cysts
• Remnants of the dental
lamina that do not
develop into a tooth bud
• May degenerate to form
dental lamina (inclusion)
cysts
• Tiny keratin-filled cysts
Copyright © 2017 Wolters Kluwer · All Rights Reserved
9. Natal Teeth
• Teeth that are present at
birth or erupt within 30
days of birth
• Cornified and calcific
material
• Represent premature
eruption of the primary
teeth

10. Eruption Cyst
• AKA: Gingival Eruption
Cyst, Eruption Hematoma
• Variant of the dentigerous
cyst
• Lined by odontogenic
epithelium

11. Lymphangioma
• Benign malformation of
lymphatic vessels
• Tongue, alveolar ridge,
and labial mucosa
Copyright © 2017 Wolters Kluwer · All Rights Reserved
12. Thrush
• AKA: Candidiasis,
moniliasis
• Fungal
• Milky white curds
• Easily wiped off
• Tx: antifungal agents

13. Parulis (Gum Boil)
• Inflammatory response to
a chronic bacterial
infection of a nonvital
tooth
• Pulpal infection spreads
beyond the furcation of a
posterior tooth
• Drains through sinus tract

Lip Pits
• Congenital depressions or dimplelike invaginations
• Inherited pattern often
• Commissural lip pits (corner of the lips)
– Failure to fuse
• Paramedian lip pits (mandibular lip)
– Either side of the midline
– If with cleft lip or palate + hypodontia = van der
Woude syndrome
• Treatment is not required unless for cosmetic reasons
