Clinical and radiological evaluation of Inverse impaction of supernumerary teeth

Abstract

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.

“…[5][6][7] Çok sayıda süpernümerer dişe aynı olguda rastlanması çok nadirdir ve genellikle sistemik bir rahatsızlık veya sendromla birlikte görülür. Süpernümerer dişlerin en sık görüldüğü sendromlar Gardner Sendromu, EhlerDanlos Sendromu, Kleidokranial Disostozis, NanceHoran Sendromu, Fabry-Anderson Sendromu, Trikorinofalangeal Sendrom ve dudak-damak yarıkları-…”

“…1,3 Süpernümerer dişler sıklıkla erkeklerde ve premaksiller bölgede gözlenmektedir. [4][5][6][7] Literatürde süpernü-merer dişler lokalizasyonlarına göre mesiodens (iki ön kesici arasında), parapremolar (küçük azı dişler arasında) paramolar (büyük azı dişler arasında) ve distomolar (üçüncü büyük azı distalinde) olarak sınıflandırmıştır. 2,8 Süpernümerer dişler sürme bozukluğu, sürme gecikmesi, dişlerde yer değişiklikleri, yer darlığı, primordial veya foliküler kist oluşumları, ilgili bölgede ağrı ve şişlik, komşu dişlerde patolojik kök rezorpsiyonları gibi çeşitli problemlere sebep olabilmektedir.…”

Prevalence of supernumerary teeth among a sample of patients attending college of dentistry in Erbil, Iraq (A Retrospective study)

“…7 Thus, the prevalence reported in the literature of hyperdontia ranges between 0.2 -0.8% in the primary dentition, and in the permanent dentition, between 0.3 -3.8% of the general population. [8][9][10][11] Supernumerary teeth are more frequent among males than among females in a proportion of 2:1. [12][13] Supernumerary teeth occur singly or in multiples, unilaterally or bilaterally, either in maxilla, mandible, or both.…”

Prevalence of impacted teeth among a sample of Yemeni population and their association with sex and age

“…2 This is because of the potential complications and possible risks to function and desired esthetics and may be even associated with psychological effects. 3 Tooth impaction is its failing to erupt in order to reach the occlusal plan even after completion of twothirds of its root, so it is covered by mucoperiosteum and bone because of abnormalities such as malposition, lack of space, odontoma, excessive soft tissue, endocrine diseases, or due to obstruction by another tooth. 4,5 Furthermore, impacted teeth are often associated with pericoronitis, periodontitis, cysts, neoplasm, root resorption of the adjacent tooth and can cause detrimental effects on adjacent teeth.…”
