Root-end resection

Abstract

Root end resection (RER) or apicoectomy is a operating removal of the apical root tip. Together with root resection and closure of lateral perforations they belong in the area of chirurgical endodontics (1). The main indications for RER are anatomic problems, procedural accidents, irretrievable materials in the root canal, symptomatic cases, and horizontal apical fractures as well as biopsy and corrective surgery (2). Goal of the procedure is the removal of atypical, or complicated aligned apical ramifi cations with the surrounding in most cases infected tissues. If the root end resection is indicated it should be considered as a extension of nonsurgical treatment, because the underlying etiology of the disease process and the objectives of treatment are the same: prevention or elimination of apical periodontitis (3). Aim of the apicoectomy should be creating a surrounding that helps periodontium to regenerate -eliminate the etiological factors, avoid recontamination of the periradicular tissue, sanation and regeneration of the alveolar bone, periodontal ligaments and cementum covering the root and root end fi lling (4, 5). Methods Analysis ResultsTotal number of patients and Sex: In the following period 285 pacient underwent RER. 36.14 % were males (n=103) and 63.86 % (n=182) were females. Figure 1 describes the number of patients that were treated each year in the following period depending on sex.Age structure: The next examined factor was the age structure of the patients who underwent RER in the following period. They have been devided in 6 age groups. Up to 25.26 % (n=72) of all patients were in the (21-30) (Fig. 2).The 10 most resected teeth: The teeth from the fi rst and second quadrant are the most resected. The central and lateral right incisors with a total number of 47 (12.43 %) resections each are fi rst ranked. Followed by the RER of lateral and central left incisor 46 (11.88 %) and 43 (11.38 %). Lower ranked are the upper canines and premolars. On the rank 9 and 10 are the central incisors from the fourth and third quadrant (Tab. 2).

Apicectomia associada à regeneração óssea guiada: relato de caso

“…Segundo Blahuta e Stanko, os objetivos da apicectomia são a eliminação dos fatores etiológicos, evitando a recontaminação do tecido periapical, e também a regeneração do ligamento periodontal e do tecido ósseo nessa região [3].…”

“…A cirurgia de apicectomia é uma técnica amplamente descrita e aceita que consiste na ressecção da extremidade ou porção apical da raiz, tendo como principais indicações fraturas apicais horizontais, materiais irrecuperáveis na raiz, acidentes durante a endodontia, problemas anatômicos, cirurgias corretivas, biopsias ou após a falha do tratamento endodôntico, tendo como objetivo a preservação de dentes com lesão ou patologia apical [3,4].…”

Prehistory of Košice – settlement in the Neolithic

“…Spouted vessels were also found at the latter two sites, Ľubotice-Šarišské Lúky 111 and Kapušany. 112 A spout with perforations 113 is known from Košice-Barca I. 114 Spouted vessels have also been found at the Hungarian sites of Tiszavasvári-Keresztfal, 115 Polgár-Nagy Kasziba 116 and Hajdúnánás-Eszlári út.…”
