25. Hypocalcification (poor quality of enamel) on two permanent maxillary central incisor teeth. This snowcap effect is due to an intrusion injury to primary incisors at about on year of age. This appearance can also be an hereditary phenomenon.
26. Intrusion of primary incisors following traumatic injury at age three.
27. Infected and ankylosed teeth. By age six, if the primary incisors
ankylosed, they should be extracted.
28. Radiograph arrested development of the permanent incisors. Normal
development of adjacent permanent incisors may be seen.
29. Lingual eruption of a permanent mandibular incisor behind primary incisors. Normal exfoliation of the primary teeth usually will result in the permanent incisors assuming normal position. Extraction should not be considered until the permanent incisors have erupted to the level of the occlusal plane.

resorbed and gingival tissue showing through the enamel (pink hue to enamel).

35. Radiograph showing supernumerary tooth (mesiodens) preventing eruption of the permanent incisor.
36. Supernumerary teeth - Maxillary incisor area is the most common site for supernumerary teeth. Some erupt while many do not and prevent permanent incisor eruption.
37. Nursing bottle pacifier used by five year old. Prolonged use of nursing bottle as a pacifier is associated with characteristic pattern of tooth decalcification.
38. Early childhood caries in a two year old.
39. Effects of using bottle as a pacifier shown by 3 ½ year old. Only the mandibular incisors are not affected; presumably they were protected by the tongue during nursing.
40. Extreme decalcification of all maxillary teeth shown by six year old. Use of the bottle continued until age six. Normal primary and permanent mandibular teeth show that cause of the decalcification is not systemic.
41. Rampant Caries -- NOT typical of early childhood nursing caries.
42. Enamel Fluorosis - generalized white fluorosis
43. Enamel Fluorosis- affected permanent first molars, normal second molars. The result of systemic overdose from birth to 3 years.

48. Partial removal of the green stain with professional prophylaxis.
49. Black stain or pellicle formation found throughout the mouth is difficult to remove and is associated with a high resistance to caries.
50. Periodontal diseases in childhood. Children are different!
51. Gingivitis periodontal diseases in childhood is usually due to poor oral hygiene and is easily reversible with oral hygiene improvement.
52. Calculus in a primary dentition. In the young child the calculus is soft and chalky, usually in the mandibular incisor area. Generalized calculus deposits are frequently seen in children fed by a gastric (G) tube.
53. Calculus in a two year old seen on maxillary molar. Most common sites if calculus formation are buccal surfaces of the maxillary molars and lingual surfaces of the mandibular incisors.
54. Periodontal disease in 12 year old caused by calculus deposits.
55. Healing three weeks after calculus has been removed. The gingival surrounding the mandibular incisor now appears healthy.
56. Calculus formation around the mandibular incisors of a 12-year-old girl with spastic cerebral palsy, mouth breathing and a tongue thrust habit. Deposits are so heavy that the teeth will be lost in a few years if treatment is not begun and continued and oral hygiene dramatically improved.
