SUMMARY. Aim: The objective of the study was to evaluate the impact of dental lesions on the periodontium, in a canine model of mandibular osteodistraction. Material and methods: In six adult male Beagle dogs, an osteotomy was made between the right second lateral incisor and canine, and a distraction device placed. The roots adjacent to the osteotomy were deliberately damaged by the reciprocating saw and chisel, with preservation of the attached gingiva. The osteodistraction protocol used was: latency of 7 days, rate of distraction 1 mm per day, and rhythm once a day for 5 days. Vital staining was carried out with tetracycline, Xylenol Orange and Calcein Green. The dogs were sacrificed after 12 weeks of consolidation and the specimens were evaluated with light microscopy (native, polarized light, fluorescence, and after toluidin blue staining). Results: The periodontal ligament (PDL) regeneration was observed in the 2500 slices examined. Cementum and dentine lesions were repaired by cellular cementum. Loose dentine and cementumedentine fragments were embedded in regenerated PDL and their surface repaired by cementum. By means of light microscopic examination and within the limited observation time, no degenerative pulpal changes were found, when the pulp canal was not entered. Extensive pulp exposure and destruction resulted in ingrowth of the PDL and bone-like tissue. In that case, cellular cementum also lined the dentine surface of the pulp canal. Conclusion: Although there was an extensive reparative response to the para-pulpal lesions, none of the changes observed showed evidence of a loss of functional integrity of the periodontium at the distraction site. The fate of the tooth with exposed pulp canal remains uncertain. Ó 2008 European Association for Cranio-Maxillofacial Surgery

“…The lengthening of the formed callus, or callotasis, is achieved progressively by daily activations of the distraction device. The mineralization of the callus is initiated after the third week following the end of activations (consolidation period) 2,7 .…”

“…In fact, it has been shown that if the osteotomy leads to exposure of the root, the osseous formation cannot be achieved on the tooth. The presence of bone on both sides of the osteotomy is therefore desirable in order to optimally induce osteogenesis 2,4 . Besides, it is sometimes necessary to open the observed overbite of Brodie's Syndrome in order to allow for an expansion without occlusal interference.…”

“…The dental distractor is usually attached to the lingual surface of the teeth and is the source of discomfort and hygiene problems. Moreover, its impact is more dentoalveolar than basal and it creates a labioversion of the lower incisors 2,11,18 . Because of this, the rate of relapse is increased since the alveolar expansion is not supported by the basal bone 17 .…”

“…This phenomenon called ''walking-teeth phenomenon'' is due to the elastic traction of the transseptal fibers of the periodontal ligament 2,14 . Once the activations are stopped, a period of consolidation is necessary (Fig.…”
