“…All subjects in both groups showed normal root length of MXC on the cleft side compared to the noncleft side. This was similar to the study by Park et al 15 that reported that, although the UCLP group showed delayed development of MXC on the cleft side compared to the noncleft side one month before SABG, the MXC on the cleft side developed faster than that on the noncleft side after SABG, eventually resulting in no difference in the Nolla stage.…”

Objectives To investigate whether absence of maxillary lateral incisor (MXLI) would affect the status of maxillary canine (MXC) before and after secondary alveolar bone grafting (SABG) in patients with unilateral cleft lip and alveolus (UCLA) and unilateral cleft lip and palate (UCLP). Materials and Methods 47 male patients with UCLA and UCLP, whose Bergland indices were type I or II after SABG, were divided into the MXLI-absence (n = 26) and MXLI-presence groups (n = 21). Using panoramic radiographs, the position, angulation, and development status of MXC on the cleft side, and the cleft width before SABG (T1) were evaluated. After full eruption of the permanent dentition (T2), the root length, root shape, and frequency of forced eruption of MXC on the cleft side were investigated. Then, statistical analysis was performed. Results Compared to the MXLI-presence group, the MXLI-absence group showed higher frequencies of mesial angulation of MXC at T1 (criteria: >25°; 46.2% vs 14.3%, P < .05) and dilaceration of MXC at T2 (26.9% vs 4.8%, P < .001). MXC on the cleft side showed positive correlations between horizontal position at T1 and forced eruption at T2, and between vertical position and mesial angulation at T1 and dilaceration at T2 (all P < .01). Conclusions In patients with UCLA and UCLP whose SABG outcome was successful, absence of MXLI on the cleft side increased only the frequencies of mesial angulation of MXC at T1 and dilaceration of MXC at T2, not frequency of forced eruption at T2.

“…The 32-year-old woman reported a traumatic injury involving her teeth when she was 6 years old, age when the front incisor are in eruption route [6] and Nolla stage 7 (complete crown and 1/3 of the root's development) [12]. On the other hand, the 8-year-old girl's mother said that the white mass appeared after 3 months her daughter had been through iliac crest bone craft for oronasal fistula repair.…”

“…We did not have access to previous CT scans or other radiographic images to determine whether or not trauma and maxilla crafting were the main causes of tooth ectopic eruption. Despite the lack of previous CT scans or other radiographic images, the patients' age suggests that Nolla stage in both of them could be classified as 7 or 8 [12], which could be a facilitating factor for the tooth displacement.…”

The aim of this study was to report two rare cases of ectopic tooth into the nasal cavity. The first case reports a 32-year-old female patient with the main complaint of having a tooth inside her nose. According to her, this condition causes pain and sporadic nosebleed. The patient had a facial trauma when she was 6 years old. The second case refers to an 8-year-old girl with left incomplete unilateral cleft lip and palate. The main complaint was left-sided nasal obstruction by a white hard mass. The treatment for both cases was surgical removal of the ectopic erupted tooth under general anesthesia. In conclusion, we can state that the surgical removal of intranasal tooth is a safe procedure and improves patient’s quality of life.

This study aims to investigate the characteristics of adjacent anatomy of mandibular third molar germs (MTMGs). Three hundred Chinese patients aged 12 to 17 years old who received cone-beam computed tomography (CBCT) were enrolled. The continuity of cortical outline of inferior alveolar canals (IACs) in the region of MTMGs, the integrity of lingual bone cortex and the relationship between hard tissue part of MTMGs and IACs were investigated by observing CBCT data via the NNT viewer software. The age, degree of dental development, gender and location were recorded as variables. The associations between different variables and the observed data were analysed. The possibilities of disrupted cortical outline of IACs or the hard tissue part of MTMGs contacting IACs were significantly lower in 12 or 13 age groups, lower in Nolla stage ≤ 6. Males were significantly less than females in the incidence of disrupted cortical outline of IACs. As to the perforation of lingual bone cortex, no significant differences were observed in gender, ages, location or development stages. According to the CBCT images, anatomical factors contributed the lest to the risk of inferior alveolar nerve and lingual nerve injury in the 12 to 13 age group during removing the MTMG removal.

Comparison of tooth development stage of the maxillary anterior teeth before and after secondary alveolar bone graft: Unilateral cleft lip and alveolus vs unilateral cleft lip and palate

Abstract: SABG performed at approximately 9 years of age might increase tooth development speed of MXC in patients with UCLP compared with patients with UCLA.
