“…Impacted ST are of great concern in children and young adolescents also to both dentists and the parents because of the existing complications or potential risks to proper function and desired esthetics and even of the related psychological effects. The inversion of ST more likely causes a tendency for such conditions (9,10). They are occasionally encountered in the clinical practices of pediatric dentistry and oral surgery (6) and clinical complications associated with ST are one of the major reasons why patients seek dental care (11).…”

“…An impacted tooth is the one that fails to erupt into the dental arch within the expected time. The development of a supernumerary tooth with the crown in a deviated position such as an inverted tooth is less common (9,10). Inversion complicated by impaction is most frequently observed in the maxillary cuspid, followed by maxillary anterior ST, maxillary central incisors, lateral incisors and the mandibular third permanent molars (5,10).…”

Objective: To describe the clinical and radiological features of children with inverted supernumerary teeth. Study Design: Thirty eight patients with inverted supernumerary teeth (ST) were enrolled in this descriptive and restrospective study. Data from patient records including age, gender, status of dentition, number of ST, number of ST in inverted position, coexistence of ST in inverted and normal direction of eruption, location, orientation, morphology, clinical complications, management and radiography were assessed during 3-years period. Results: Thirty eight patients with a mean age of 9.10±1.97 years (range:6-13) and a strong male preponderance of 3.7:1 (male:30, female:8) had a total of 69 ST, of which 41 were in inverted position. Thirty five patients had one (92.1%) inverted tooth, whereas 3 patients had two inverted teeth per case (7.9%). All cases were located in the maxilla. Midline was the most frequent site for the single inverted supernumerary tooth in 18 (47.4%) patients, followed equally by the right and left premaxillary region in 10 patients each (26.3%). Regarding morphology, 30 patients had conical (78.9%) and 8 (21.1%) had incisiform ST. No tuberculate shaped ST was detected. There was no statistically significant difference between number of inverted teeth and delayed tooth eruption, diastema, local malocclusion, palatinal swelling (p>0.05). There was no statistically significant difference between complications and age (p>0.05). Surgical removal at the time of diagnosis with subsequent follow-up during completion of permanent dentition was the treatment approach in all cases. Conclusions: Thorough clinical examination followed by a comprehensive radiographic screening is the crucial determinant of an accurate diagnosis of an impacted ST. Early diagnosis and timely management are key factors to prevent or minimize the complications, which may influence function and esthetics of the teeth and even psychological condition of the growing child. Key words:Supernumerary tooth, impaction, inverted.

“…An inverted supernumerary tooth is rather uncommon. Eruption of inverted teeth is extremely rare, but has been described for mesiodens and premolars (33). Treatment depends on the type and position of the supernumerary tooth and on its effect on adjacent teeth.…”

While dental 2D radiology is still the most frequent diagnostic tool, the inherent nature of jaws and teeth might surely benefit from 3D diagnosis. Nowadays, dental cone beam computed tomography may offer high quality images at low radiation doses and costs. Yet, effective dose ranges of CBCT machines may easily vary from 10-1200 microsievert, being an equivalent of 2 to 240 dental panoramic radiographs. The same holds true for diagnostic image quality, which exhibits a huge variation amongst machines and parameter settings. For segmentation accuracy, lower limits of accuracy are around 200 micrometer, yet again, larger inaccuracies may apply. For linear accuracies, values below 500 micrometer are feasible, with some machines and CBCT parameter settings allowing linear accuracies of up to 200 micrometer. Apart from the radiodiagnostic possibilities, dental cone beam CT may offer a vast therapeutic potential, including possibilities for surgical guidance and further treatment via CAD/CAM solutions for crown and bridgework on teeth or implants. In conclusion, dental CBCT imaging could be justified when dealing with specific indications including jaw bone and maxillofacial surgery, endodontic retreatment, traumata, jaw bone lesions and TMJ pathology. Yet, guidelines for CBCT optimisation and justification are mandatory, especially when used for pediatric indications.

Anterior maksillada süpernumerer dişin inverse erüpsiyonu: Nadir bir olgu raporu Literatürde hem maksillada hem de mandibulada inverse diş erüpsiyonları bildirilmiştir ve bunların çoğu inverse gömülü üçüncü büyük azı dişleri ve küçük azı dişleridir. Ancak, ağız içi inverse diş erüpsiyonu günümüze kadar çok az durumda bildirilmiştir. Biz burada maksillada merkezi ve yan kesici dişler arasındaki inverse süpernumerer dişle ilgili benzersiz bir olguyu bildirmekteyiz. Anahtar sözcükler: İnverse diş, süpernumerer diş, maksilla ABS TRACTA rare case report of inverted eruption of supernumerary tooth in the anterior maxilla Inverted teeth have been reported in both maxilla and mandible and most of them are inverted impacted third molars and premolars. However, very few cases of intraoral inverted tooth eruption have been reported till date. We are reporting a unique case of inverted supernumerary teeth between the central and lateral incisors in the maxilla.
