Introduction: For dental avulsion, surgery may be invasive where it affects bone volume and may cause damage to the surrounding anatomical structures. Piezosurgery is a minimally invasive surgery due to the thin and precise cutting of the tooth compared with conventional burs. Technique: the authors have presented the case of a thirteen-year-old girl referred by her orthodontists for the extraction of a supernumerary tooth. The anterior nasal spine (ANS) was cut using piezosurgical techniques, repositioned and fixed using osteosynthesis with a bone screw. Postoperative follow ups were promising, and the bone screw was taken out a year later. Comments: The preservation of the nasal mucosa had probably aided in the trophicity and healing of ANS. The minimal bone loss by piezosurgical techniques allowed for the replacement of ANS and its osteosynthesis. Conclusion: This case describes a minimally invasive procedure which allowed for the removal of a deeply impacted supernumerary tooth, without damaging the surrounding teeth or nasal mucosa, and maintaining ANS bone volume.

Although primary surgery for cleft lip has improved over time, the degree of secondary cleft or nasal deformity reportedly varies from a minimum degree to a remarkable degree. Patients with cleft often worry about residual nose deformity, such as a displaced columella, a broad nasal floor, and a deviation of the alar base on the cleft side. Some of the factors that occur in association with secondary cleft or nasal deformity include a deviation of the anterior nasal spine, a deflected septum, a deficiency of the orbicularis muscle, and a lack of bone underlying the nose. Secondary cleft and nasal deformity can result from incomplete muscle repair at the primary cleft operation. Therefore, surgeons should manage patients individually and deal with various deformities by performing appropriate surgery on a case-by-case basis. In this report, we applied the simple method of single VY-plasty on the nasal floor to a patient with unilateral cleft to revise the alar base on the cleft side. We adopted this approach to achieve overcorrection on the cleft side during surgery, which helped maintain the appropriate position of the alar base and ultimately balanced the nose foramen at 13 months after the operation. It was also possible to complement the height of the nasal floor without a bone graft. We believe that this approach will prove useful for managing cases with a broad and low nasal floor, thereby enabling the reconstruction of a well-balanced nose.

Objective: To elucidate the prevalence of developmental anomalies of permanent lateral incisors among young patients in Japan. Study deign: A total of 1375 patients were observed between 1990 and 2008 at the Department of Pediatric Dentistry in the Kyushu Dental College Hospital and four private pediatric dental clinics in Kitakyushu City. Panoramic and periapical radiographs were examined for all those patients aged 5 to 19 years. Results: The prevalence of agenesis of the lateral incisors was 7.3% (100 patients), with more girls than boys being affected. The prevalence rates of absent upper and lower lateral incisors were 2.7 and 4.8 % (34 and 63 patients), respectively. Nine (0.7 %) of the total patients had microdontia. Eruption disturbance was present in five patients (0.4 %). Two of five patients presented with a disturbed eruption owing to an odontoma or a supernumerary tooth. Conclusion: In our study, the prevalence of agenesis of the lateral incisors was higher in Japanese children than in other populations, and eruption disturbance occurred less frequently than agenesis and microdontia. Nevertheless, the early differential diagnosis of an eruption disturbance is important in order to begin appropriate treatment at the optimal time.

Mesiodens is a midline supernumerary tooth commonly seen in the maxillary arch, and incidence of molariform mesiodens in the maxillary midline is rare in permanent dentition and extremely uncommon in primary dentition. A midline supernumerary tooth in the primary dentition can cause ectopic or delayed eruption of permanent central incisors which will further alter occlusion and may compromise esthetics and formation of dentigerous cysts. This paper reports a rare case of the presence of a molariform mesiodens in the primary dentition. On clinical and radiographic examination, flaring of the primary central incisors was seen, with a molariform mesiodens consisting of multiple lobes or tubercles on the occlusal surface with the well-formed root. The treatment plan consisted of the extraction of the supernumerary tooth and regular observation of permanent central incisors for proper eruption and alignment.

The purpose of this clinical case report is to discuss the approach to oral rehabilitation of a patient with severe dental alterations such as enamel hypoplasia, change in shape, supernumerary tooth, dental ankylosis, agnesia and crowing in the incisor region. All of these problems compromised not only the esthetical and functional aspects of this patient, but his social relationships as well. Thus integrated planning between Pediatric Dentistry and Orthodontics made it possible to provide the best treatment alternative to recover the patient's stomatognathic system. Esthetic restorations were performed in the anterior tooth region with the use of resin composites, in addition to the use of removable orthodontic appliances, associated with serial extractions and supernumerary tooth removal. There were significant improvements in the esthetic and functional aspects of dentition, in addition to the patient demonstrating good evolution in his psychosocial condition, as he smiled and was more communicative during each follow-up appointment, also according to his mother's reports.
