The facial cleft and duplicated maxilla are lire congenital anomaly. After Rushton and Walker had reported a unilateral facial cleft with excess tooth and bone formation in 1937, few authors described similar cases. The etiology of this anomaly is not well understood, but considered embryologically as a neurocristopathy. A neurocristopathy is defined as a condition arising from aberrations in early migration, growth and differentiation of neural crest cells. This aberrations result in facial malformation such as facial clefts and loss or duplication of facial structures. We experienced a male newborn baby with bilateral facial cleft and duplicated maxilla. The cleft was surgically corrected when he was 5 months old. The function and appearance of lip are improved. Duplicated maxilla will be surgically removed. We report this case with review of literatures.

Pulsus paradoxus has been defined as a decrease in systolic blood pressure (SBP) of 10 mmHg or more during inspiration. This report describes pulsus paradoxus detected by pulse oximetry during dental procedure. Case: A 10 years old boy who had impacted mandibular premolar with malformation scheduled for extraction under intravenous sedation with Fentanyl and Propofol. The patient showed upper airway obstruction with stridor and pulsus paradoxus. Though pulsus paradoxus is generally critical condition, in this case, respiration and other vital sign was maintained comparatively well with care in administering oxygen and considerate monitoring of pulse oximetry and capnography. Discussion: Noninvasive continuous monitoring of pulse oximetry allows recognition of pulsus paradoxus which can lead to serious problems. Clinicians should know very well about it and be able to manage of this kind of situation.

Regional odontodysplasia (RO) is a rare and nonhereditary dental malformation. It is a dental alteration of unknown etiology, involving both mesodermal and ectodermal dental components, which is characterized by clinical, radiographic, and histologic features. The maxilla is more often involved than the mandible (especially the left side), and there is no racial predilection, but females are affected twice as often as males. The affected teeth are clinically hypoplastic and hypocalcified, presenting a "ghost-like" appearance radiographically. The present case features a male patient aged 4 years and 6 months who was diagnosed with regional odontodysplasia in the maxilla on the right side, confirmed by clinical and radiographic examination, with a follow up of 5 years. Since teeth affected by RO have a poor prognosis due to the fragile tooth surface and open apices, the long-term treatment strategy depends on periodic clinical and radiological observations.

Cleft lip and palate are congenital craniofacial malformation. Reconstruction of dental arch in patient with alveolo-palatal clefts is very important, because they have many problems in functions and esthetics. Malnutrition, poor oral hygiene, respiratory infections, speech malfunctions, maxillofacial deformity, and psychological problems may be occured without proper treatment during the long period of management of the cleft lip and palate. So the treatment should be managed with a multidisciplinary approach. Bone grafting is a consequential step in the dental rehabilitation of the cleft lip and palate patient A complete alveolar arch should be achieyed of the teeth to erupt in and to form a stable dentition. And the presence of the cleft complicate the orthodontic treatment. Therefore bone grafting in patients with cleft lip and palate is a widely adopted surgical procedure. Grafted bone stabilizes the alveolar process and allows the canine or incisor to move into the graft site. After the bone grafting, orthodontic closure of the maxillary arch has become a common practice for achieving dental reconstruction without any prosthodontic treatment. Various grafting materials have been used in alveolar clefts. Iliac bone is most widely fovoured, but tibia, rib, cranial bone, mandible have also been used. And according to its time of occurrence, the bone graft may be divided into primary, early secondary, secondary, late secondary. Bone grafting is called secondary when performed later, at the end of the mixed dentition. It is the most accepted procedure and has become part of treatment of protocol A secondary bone graft is performed preferably before the eruption of the permanent canine in order to provide adequate periodontal support for the eruption and preservation of the teeth adjacent to the cleft. In this report, we report here on a patient with unilateral cleft lip and palate, who underwent iliac bone graft. The cleft was fully obliterated by grafted bone in the region of the alveolar process. The presence of bone permitted physiologic tooth movement and the orthodontic movement of adjacent tooth into the former cleft area. Satisfactory arch alignment could be achieved in by subsequent orthodontic treatment.
