Negative correlation was seen between the mesiodistal crown width of the mandibular second molar and the available space in stage 2. Positive correlation was seen between the mesiodistal crown width of maxillary second molar and the available space in stage 3. It is suggested that greater increase in the space available for emergence of the second molar could be expected in the maxillary dental arch, if the mesiodistal crown width of the second molar required it. The eruption cyst is a type of soft tissue cyst associated with erupting teeth. It occurs usually in childhood, and they appear to be more prevalent in the maxillary arch.
Systems affected include skin, musculoskeletal, urinogenital and orofacial.
The child is of normal intelligence and good general health. The use of a transcoronal wire is recommended as a rapid and safe method to force the eruption of the unfavorable impacted canines. Minimal surgical exposure of the crown is necesary to place a transcoronal wire which can be easily inserted during surgery. Although the canine in the presented case was in an unfavorable position, and the root already formed, it was moved from its initial high position to occlusion in about one year with no loss of vitality and no periodontal anomalies.
