Background: Many classifications of impacted maxillary canines on CBCT are present in literature, but they do not take into consideration root resorption and KPG index jointly. Moreover, the latter only considers the anterior-posterior, vertical and axial viewpoint, without taking into account the impacted canine perspective in the mesial-lateral perspective. The present study is aimed at implement the already existing classifications of impacted maxillary canines on CBCT that do not take control over the apico-root resorption and the KPG index, also associating the angular measurements of the canine in the mesial-lateral perspective. Objectives: The aim of the present study is to validate a new classification system of impacted maxillary canines on CBCT assessing the apex-root structural changes and the KPG index. Materials and methods: A bibliographical reserch was carried put using the main databases as Pubmed and Scopus for the already existing classifications of impacted maxillary canines on CBCT. The research was conducted using the following keywords: “impacted maxillary canines”, “impacted canines opt” “impacted canines CBCT”, “classification impacted canines in CBCT”, “root resorption” “canine ankylosis”, “cone beam computed tomography”, “eruption cyst”, “dentigerous cyst”. The time interval has been set from 1980 until today. The articles have been selected according to the abstract and/or the full text without setting limits on languages. Experimentally, the present study has screened the CBCT and, in the presence of impacted maxillary canines, the vertical, lateral, vestibular-palatal, mesial-distal and mesial-lateral positions has been assessed on the sagittal, coronal and axial planes. Moreover, location and severity of apical-root resorption of neighbouring teeth has been considered.
Background: Sono già presenti in letteratura delle classificazioni di canini mascellari inclusi in CBCT, ma non vengono presi in considerazione congiuntamente il grado di riassorbimento apicale e l’indice KPG. Quest’ultimo inoltre valuta solo l’angolazione antero-posteriore, verticale e assiale, non considerando l’angolazione del canino in senso mesio-laterale. Il presente studio è volto ad implementare classificazioni di canini mascellari inclusi su CBCT già esistenti che non prendono in controllo il grado di riassorbimento apico-radicolare e indice KPG, associando inoltre angolazione del canino in senso mesio-laterale. Scopo dello studio: Lo scopo del presente studio è validare un nuovo metodo di classificazione dei canini mascellari inclusi CBCT valutando il rimaneggiamnto apicale e implementando l’indice KPG. Materiali e metodi: È stata effettuata una ricerca bibliografica utilizzando le principali banche dati quali Pubmed e Scopus per le classificazioni di canini mascellari inclusi già esistenti in CBCT. La ricerca è stata condotta utilizzando le seguenti parole chiave: “impacted maxillary canines”, “impacted canines opt” “impacted canines CBCT”, “classification impacted canines in CBCT”, “root resorption” “canine ankylosis”, “cone beam computed tomography”, “eruption cyst”, “dentigerous cyst”. L’intervallo temporale è stato fissato dal 1980 ad oggi. Gli articoli senza porre limite di lingua verranno selezionati in base all’analisi del contenuto dell’abstract e/o dell’articolo full text. Sperimentalmente con il seguente studio verranno screenate le CBCT e, in presenza di canini mascellari inclusi, verranno valutate sul piano sagittale, coronale e assiale: l’angolazione verticale, laterale vestibolo-palatale, mesio-distale e mesio-laterale (implementazione indice kpg). Verrà inoltre preso in controllo il grado di riassorbimento apico-radicolare degli elementi dentali adiacenti.
