Study group: Fifty-seven children with craniosynostosis and their matched controls. Outcome measures: The decayed, missing, and filled teeth and surfaces in both the deciduous (dmfs and dmft) and the permanent dentition (DMFS and DMFT). The plaque and gingivitis scores and developmental enamel defects were also recorded. The caries-related microflora was sampled using an alginate swab and the prevalence of Streptococcus mutans and Lactobacillus and Candida species were recorded. Results: The dmfs (p Ͻ .02) and dmft (p Ͻ .01) were significantly greater in the control children. The plaque score for the deciduous dentition only (p Ͻ .02) and also the gingivitis score for the permanent teeth only (p Ͻ .008) in the craniosynostosis group were significantly greater. The total aerobic bacterial count (p Ͻ .004), anaerobic count (p Ͻ .002), and Candida count (p Ͻ .05) were significantly greater in the control group. The proportion of S. mutans both as a percentage of the total anaerobic count (p Ͻ .04) and the total streptococcal count (p Ͻ .05) was significantly greater in the control group.

The involved tissues are the periodontal ligament (PDL), the alveolar bone, the gingiva, the pulp and the cementum (1). The healing process is a very complex one and it is affected by various factors, including the age of the patient, length of extraoral storage period, storage medium used and replantation management, amongst others (2). There is strong scientific evidence that avulsed permanent teeth recover their function and aesthetics after replantation under ideal conditions, and PDL healing is an important success factor in immature or mature teeth (3). Immediate replantation into its own socket is one of the strongest factors contributing to favourable PDL healing in avulsed young permanent teeth (4). The results of a prospective follow-up study of 400 permanent incisors by Andreasen have reaffirmed that immediately replanted teeth-within the first 5 min-have the best prognosis for PDL healing. Nowadays, immediate replantation is the best therapy for traumatic tooth avulsion (5, 6). When large areas of PDL are lost or damaged during avulsion, healing may occur from the alveolar side of the socket and lead to a union between the root surface and the alveolar bone, and disappearance of the PDL space. This fusion is known as dentoalveolar ankylosis or replacement resorption, the most frequent PDL healing complication and the most difficult to diagnose in replanted teeth (4). This type of resorption is progressive, and eventually involves the entire root. The rate of resorption varies with age and growth rate. Replacement resorption will be faster in 8-to 16-year-old patients than in older patients, where the involved tooth may remain functional for a longer time (7). There is no treatment for arresting or reversing this condition to date (8). Clinical signs of ankylosis like high metallic percussion sound and restrictedor absence of-tooth mobility often precede the radiographic diagnosis. In those cases, when labial and/or lingual root surfaces are compromised by replacement resorption radiographs are unable to show this healing phenomenon rendering the diagnosis more difficult. This clinical entity can be diagnosed during the first 2 months after injury and most often within a year after a severe trauma (9).
