Six months after insertion of the grafts, the bone of the augmented sinus floor was strong and suitable for anchorage of dental implants, irrespective of whether autogenous bone or Cerasorb particles had been applied.

Cleidocranial dysplasia (CCD) is an uncommon, generalized skeletal disorder characterized by delayed ossification of the skull, aplastic or hypoplastic clavicles, and serious, complex dental abnormalities. There are many difficulties in the early diagnosis of CCD because a majority of the craniofacial abnormalities becomes obvious only during adolescence. In the present case, a hypoplastic midface, a relative prognathia of the mandible, and close approximation of the shoulders in the anterior plane were the conspicuous extraoral findings. Prolonged exfoliation of the primary dentition, unerupted supernumerary teeth, and the irregularly and partially erupted secondary dentition produced occlusional anomalies. The presence of the second permanent molars together with the primary dentition and wide spacing in the lower incisor area were typical dental signs. Gradual extraction of the supernumerary teeth and over-retained primary teeth was the first step of oral surgery. This was followed by a surgical exposure of the unerupted teeth by thinning of the cortical bone. Orthodontic treatment was aimed at parallel growth of the jaws. Removable appliances were used to expand the narrow maxillary and mandibular arches, and a Delaire mask compensated for the lack of sagittal growth of the upper jaw. Temporary functional rehabilitation was solved by partial denture. When the jaws have been fully developed, implant insertions and bridges are the therapeutic measures. The reported case and the literature data support the importance of the early diagnosis and interdisciplinary treatment of CCD.

Little is known about the characteristics of cutaneous sinus tract (CST) of dental origin in children. 28 cases of CST of dental origin in children were evaluated. Age, sex, site of skin lesion, duration until diagnosis, teeth involved, etiology, treatment, and outcome were recorded. The last dental care visit was also recorded. The mean age was 10.25 years (range 4-16). The male to female ratio was 1:1.74. The mandibular-submandibular area was the most common site of skin lesions. The mandibular first molar was the most involved tooth, followed by the mandibular incisor. Caries was the most common etiology. The mean duration of lesions until correct diagnosis was 6.5 months (range 0.3-12 mos). The treatment was root canal therapy or extraction. After appropriate dental treatment, CSTs resolve rapidly. Surgical revision of the scars were indicated in eight (29%) patients, to provide better cosmetic results. In these patients, the duration of lesions were longer. Preventive dental care, as indicated by last dental care visit, was poor. CST in children is different from that in adults in terms of sites of skin lesions, duration of lesions, and involved tooth and similar to that in adults in terms of etiology and treatment modality. Early treatment of the dental infection may cause healing of the cutaneous lesion spontaneously, without a scar.
