case_images: Flattened nasal bridge, macrocephaly, prominent forehead, short neck, large ears, and rounded eyebrows were observed (Figure 1).
case_images: Pre-dental treatment intra-oral photographs. (a) and (b) Right and
  left frontal views show gingival overgrowth, macroglossia,
  widely spaced teeth, malocclusion, and anterior open bite. (c)
  Maxillary occlusal view shows generalized marginal gingivitis
  around widely spaced primary dentition. (d) Mandibular occlusal

case_images: In addition, the patient had an anterior open bite, gingival overgrowth, macroglossia, malocclusion, widely spaced teeth, and incompetent lips (Figure 2).
case_images: Peri-apical radiographs of all quadrants showing enlarged pulp
  chambers of all primary molars. (a & b) Upper right and
  upper left posterior periapical radiographs, respectively. (c)
  lower right periapical radiograph shows proximal caries related
  to lower right first primary molar. (d) lower left periapical
  radiograph shows dento-alveolar abscess related to lower left
  primary molars.

case_images: Intra-oral photographs of postdental treatment. (a) Frontal view
  shows improvement of gingival health and erupting of permanent
  anterior central incisors. (b) Maxillary occlusal view shows
  stainless steel crown on upper right second primary molar. (c)
  Mandibular occlusal view shows stainless steel crown on lower
  right first primary molar, partial healing of extraction
  sockets, and initiation of eruption of lower permanent first
  molars.

case_images: He returned 1 week later for his postoperative follow-up (Figure 4).
case_images: PMC8679027_04
case_images: Panoramic radiograph of the patient in the last follow-up visit, at
  the age of 10 years. He is in mixed dentition phase with normal
  development of teeth. Failure of exfoliation of upper primary
  lateral incisors is noticed regardless of eruption of permanent
  lateral incisors.

case_images: Figures 5-7 show the panoramic, periapical, and cephalometric radiographs of the patient at the age of 10 years.
case_images: Peri-apical radiographs of the patient in the last follow-up visit,
  age 10 years. All the radiographs shows diminished pulp chamber
  size of all remaining primary molars compared to intra-oral
  radiographs at age 6 years and shows physiological root
  resorption of primary molars due to eruption of premolars. (a)
  Upper right posterior periapical radiograph shows intact
  stainless steel crowns (SSCs) of the two primary molars. (b)
  Upper left posterior periapical radiograph, shows sound primary
  molars. (c) lower right periapical radiograph shows intact pulp
  therapy and SSC related to lower right first primary molar. (d)
  lower left periapical radiographs shows eruption of the two
  premolars.
