Type of practice: Endodontic. A patient sought treatment for a chief complaint of a gingiva/tooth abscess in a previously endodontically treated tooth (Figure 1): Figure 1: Pre-operative periodical radiograph of tooth being retreated. After accessing the mesiobuccal canal, I detected a prior furcation strip perforation Rips, Strips and Broken Tips: Handling the Endodontic Mishap. May 1, 2006. by Steven Cohen, DDS, Cert. Endo, Gary Glassman, DDS, FRDC (C), Richard Mounce, DDS. In the Glossary of Endodontic Terms (7th edition, 2003) published by the American Association of Endodontists, the term perforation is defined as: the mechanical or pathologic. . The causes of perforations are resorptive defects, caries, or iatrogenic events that occur during and after endodontic treatment. Regardless of etiology, a perforation is an invasion into the supporting structures that. Causes of tooth perforation include resorption, caries, and operator performance. The prognosis for a tooth with a perforation is related to the location of the perforation, negotiability of the canal, contamination, and treatment. Alternative treatment approaches include routine endodontic treatmen
14. Root perforations are an undesired complication of endodontic treatment which result in loss of integrity of the root, Recently MTA has been introduced as an ideal material for perforation repair. In this article a successful repair of strip root perforation of mandibular molar using MTA . This case suggests that MTA may be a substitute.

canals is the position where a strip perforation could occur by over-preparation. • Strip perforate: It results from over-preparation and straining along the inner aspect of the root canal curvature. Figure 7. Strip perforation at the inner side of the curvature MANAGEMENT OF ROOT PERFORATION Definitions Root perforation is an artificial communication between the root canal system to the supporting tissues of teeth or to the oral cavity. (AAE Glossary) Accidental root perforations, which may have serious implications, occur in approximately 2-12% of endodontically treated teeth, according to Ingle, Kerekes, Seltzer and many othe Root perforation results in the communication between root canal walls and periodontal space (external tooth surface). It is commonly caused by an operative procedural accident or pathological alteration (such as extensive dental caries, and external or internal inflammatory root resorption). Differ
of the canal preparation called strip perforation, and during post-space preparation, over instrumentation of rotary instruments causes apical or crestal perforations of root canal wall, which is also called as strip perforation. During cleaning and shaping procedure, the perforation may occur in coronal, middle, or apical third of the root Strip perforation usually occurs as an iatrogenic consequence due to improper mechanical instrumentation of the root canal. It is usually an unwanted procedural accident that has a debilitating effect on the prognosis of the treatment. Usually, the accident is more prevalent in curved root canals in strip perforation of the mesial root of this mandibular molar. (B) Excessive dentin removal during attempt to remove separated instrument resulting in perforation of the root. Fig.3. (A and B) Radiographs from multiple angles, including bitewing radiographs, will facilitate diagnosis of pre-existing perforations. Regan et al. 15
Root perforation are caused either pathological by resorption and caries, or iatrogenically during root canal treatment (zip, strip, furcation perforation) or after root canal treatment (post preparation perforation). Root perforation may complicate the success of root canal treatment if not managed correctly and immediately 3- Overzealous instrumentation towards a root concavity (Strip perforation) 4- Inappropriate post space preparation B- Pathological: 1- Caries 2- Root resorption Slight extrusion of the root canal filling is called a puff or button Tooth #3 exhibiting a coronal perforation.

Root canal stripping is defined as an oblong, vertical perforation that appears especially in the middle section of curved root canals during endodontic treatments with nickel-titanium (Ni-Ti) instruments. Its occurrence may drastically affect the outcome of the treatment, transforming a common otherwise efficient endodontic procedure into a complication such as tooth extraction A tooth perforation is a pathologic or iatrogenic communication between the root canal space and the periodontal apparatus. 2 To clinically determine if an endodontically perforated tooth should be extracted or saved, the clinician must first understand the prognosis and treatment. The biologic response of a perforated tooth is inflammatory and.

Objectives To assess occurrence and its variation over time of serious accidental perforations during endodontic treatment and the fate of perforated teeth by tooth type and characteristics of. In this particular case of strip perforation, as a result of confluence, the area apical to the perforation was filled by squirting technique sequentially and packed in a continuous wave fashion. Hemostasis at the perforation site was achieved using sterile paper points curved root canal, a strip perforation may result from overpreparation along the inner side of the curvature in the middle or the coronal third of the canal (4, 13). Strip perforations signify a commu-nication between the root canal system and the periodontal ligament, mainly found in mesial root The frequency of root perforations has been reported to range from 3% to as high as 10%. 1,8,9 However, as more complex endodontic treatment cases are being attempted, it is not an unrealistic.

Timeless, state-of-the-art strategies for preventing adverse events. Richard Mounce, DDS. Iatrogenic events in endodontics can be grouped into four categories: perforations; canal blockages and transportations; separated instruments and metallic fragments; and extrusion (of various filling materials, medicaments, and media) beyond the canal system/apex Separation of endodontic ﬁles and strip perforation are among the procedural intraoperative errors. which ultimately may lead to the failure of root canal treatment [6, 7]. The possibility of. Preparing root perforations. To create root perforations in the apical and middle thirds, the root canal wall is excessively filed at the curvature area using K-files. Perforations at the cervical area (strip perforation) are made using Gates Glidden drills 1. Introduction. Endodontic stripping is an oblong, vertical perforation that occurs especially in the middle section of a curved root canal, caused by excessive instrumentation of the internal wall  during the removal of the organic material from the endodontic space and the tridimensional shaping of the canal by a progressive conical preparation
. Strip perforations occur at the coronal-third of small curved canals. The furcal area of the coronal-third in small curved roots is known as the danger zone as the dentin is relatively thin at these areas, in such cases, using a straight file or aggressive filing can cause strip perforation. [4
Hello everyone! Posting much awaited professional video of the management of floor perforation! Tough nut with multiple challenges..floor perforation, distal.. Success in endodontic treatment depends almost completely on how well the root canal is shaped and cleaned. This part will cover the principles of root canal preparation, irrigation, root length.

The actual length (AL) of the canal to the perforation site was measured using a # 70 K-file under a stereomicroscope under 20× magnification. The teeth were then mounted in an alginate mold
Introduction. Iatrogenic perforation of pulp chamber floor is an undesirable complication in dental practice that can have a negative impact on the treatment prognosis [1, 2].The size and level/location of the perforation as well as the time interval between the accident and its repair will influence prognosis .The ideal (bio)material for perforation repair should be antibacterial. The below right images (one is reversed, please forgive me) display the missed DB root in the sagittal plane as well as the apical perforation and over enlargement (strip perforation) of the MB root. The below horizontal slice displays the previous instrumentation into the furcation between the MB and DB roots
a) Apical perforations: fill as is, and if symptoms persist, then resection of the root would be the treatment of choice. That is, the tooth would have to be treated in a manner akin to that of an apical abscess. b) Middle perforations: a softened gutta-percha cone could be plugged into the perforation after gauging the dimensions of th Following simulated endodontic complications were created in 40 extracted human mandibular molar teeth: Group 1, Instrument separation (N = 10); Group 2, Strip perforation (N = 10); Group 3, Underfilling of root canals (N = 10); Group 4, Overfilling of root canals (N = 10).Intraoral and CBCT images (voxel size: 0.075 , 0.1 and 0.2 mm) were taken The post appears to strip-perforate the furcation wall of the distal root with cement extrusion and an associated furcal radiolucency. The distal root periapex demonstrates some radiographic healing (Figure 3). Figure 4. Figure 5. In January 2005, the post was removed, and a furcal perforation of the distal root was confirmed Conclusion: Considering the low thickness of the dentinal wall in the MB2 root canal compared with the MB1 root canal in the maxillary first and second molars, the anti-curvature techniques away from the furcation should be used to prepare this root canal to reduce the risk of strip perforation. On the other hand, it might indicate that highly. Endodontics.pdf - Endodontics Pulp Biology \u2022 Contains loose fibrous connective tissue with nerves blood vessels and lymphatics \u2022 Contains.

During endodontic therapy or postspace preparation, strip perforations , and vertical root fractures are possible outcomes of excessive removal of radicular dentin, especially in the danger zones where there is less amount of tooth structure compared to the peripheral portion of the root dentin preparation a strip perforation occurred, which was managed with Biodentine using an operating microscope followed by an endocrown as post-endodontic restoration (Fig. 3B ii- vii) Furcal perforation management in root canal retreatment is often challenging as the outcome of the perforation sealing depends on several parameters. The recent introduction of several bioactive cements and magnification systems has made the sealing of perforations easier and the outcome more predictable. This study highlights the clinical outcomes of furcal perforation management in root. Root canal stripping is defined as an oblong, vertical perforation that appears especially in the middle section of curved root canals during endodontic treatments with nickel-titanium (Ni-Ti) instruments. Its occurrence may drastically affect the outcome of the treatment, transforming a common otherwise efficient endodontic procedure into a complication such as tooth extraction • Old perforation- previously not treated that is contaminated with bacteria. Questionable Prognosis. • Small perforation (smaller than #20 endodontic instrument)- trauma to the tissue is small with ease of sealing, Good Prognosis. • Large perforation- this is usually seen while pos
Perforation of the pulp chamber or root walls during instrumentation of root canals exposes the supporting tissues of the tooth to bacterial contamination and often leads to loss of the tooth .Numerous reports have been published on how to handle or avoid a perforation, but less is known about the rate of these unexpected incidents in endodontics during root-canal treatments can occur during the access cavity preparation (gouging- cervical perforations), and during negotiation of the root canal for biomechanical preparation (zipping, strip perforation, canal transportation) or even during post-space preparation. These will ultimately lead to the failure of the root canal treatment. [5 The endodontic literature states that the larger the master apical diameter, the cleaner the canal preparation that results. In essence, apically, a No. 50 master apical diameter is cleaner than a No. 30 master apical diameter, etc. the risk of strip perforation, root length, root width, root curvature, and the degree of calcification. the root canal obturation. According to Bjørndal and Reit, 16. the endodontic malpractice claims were subcategorized as follows: i. Technical complications as a result of improper treatment; for example, instrument fracture, perforation, and defec-tive root fillings. A problem experienced by the patien Perform a radiographic evaluation to determine length (you can also use an apex locator), possible perforation, strip perforation or missed canals. If a perforation is noted, repair immediately with mineral trioxide aggregate (MTA) or equivalent material. If unable to perform this procedure, refer the patient to an endodontist
reasons for endodontic failure is endodontic procedural errors (such as void, over filling, under filling, gouging, furcation perforations, missed canal, over perforation, strip perforation, ledge, zipping, broken files, and apical perforation). Jafarzadeh et al (2007) reviewed ledge formation a Strip perforation was observed in the distal wall of three samples when the MB2 canals were instrumented to F2 by PTU. Table 4 presents the mean values of the remaining distal wall thickness of the mesiobuccal root and the number of specimens with a thickness under 0.5 mm after preparing the MB2 canals Root perforation is a mechanical or pathological communication between the root canal system and the supporting tissues of teeth or the oral cavity. 1 It is an undesirable and often iatrogenic accident that can occur at any stage of root canal preparation. Root perforation, which comprises about 10% of all endodontic failures, may compromise the health of periradicular tissues and disrupts the.

preparation and search for root canal orifices in the root canal treatment. [2-4] Accidental root perforations may complicate the endodontic treatment, for example, during efforts to negotiate calcified and curved canals as well as following the lateral extension of the canal preparation to a so-called strip-perforation. [5 tion, the perforated area was dilated by passing #20, #30, or #40 files through the perforation until easy passage of the files was achieved. Perforations at the cervical area (strip perforations) were made using #1-3 Gates Glid-den drills (Mani Inc., Utsunomiya, Japan) down to 3 mm below the furcation area. Considering the possibility o Mozayeni et al (2006) reported that one of the reasons for endodontic failure is endodontic procedural errors (such as void, over filling, under filling, gouging, furcation perforations, missed canal, over perforation, strip perforation, ledge, zipping, broken files, and apical perforation)
An evaluation form was used to record the data collected from the postoperative radiographs. The data included tooth type, shape of the root canal, length, presence of voids and taper of root canal fillings, separated instrument, ledge formation, strip, furcal and root perforation were examined in each root canal Fig. 9.19 Strip perforation of the mesial root of the lower left first molar, caused by the introduction of a screw post in the mesiobuccal canal.(a) Preoperative radiograph.

review. Root canal obturation was evaluated on the basis of the length of obturation being ≤2 mm from the radiographic apex, with uniform radiodensity and good adapta-tion to root canal walls. Inadequate root canal obturation included cases containing procedural errors such as furcal perforation, ledge, canal transportation, strip perfora However, accidents such as perforation, gouging, ledge and canal transportation may occur during the procedure because of an improper or incomplete access cavity design. To reduce or prevent these errors in root canal treatments, this Letter introduces an assistive augmented reality (AR) technology on the head-mounted display (HMD). The.
Strip Perforation of the root - This is a more serious problem as the stripping perforation is linear and more difficult to seal properly. However, the outcome of treatment may be acceptable for a few years if the perforation is sealed completely. An example is where a post has perforated the root canal space and a lesion developed. Figure 5 Endodontic management of Maxillary first Premolar. Discussion Root canal treatment should result in the thorough mechanical and chemical debridement of the entire pulp cavity, followed by a three dimensional obturation. Larger NiTi instruments may transport the canal space, causing strip perforations because of their rigidity

Postoperative root canal treatment resulted in a significantly lower extraction rate than did preoperative or extraoral root canal treatment among autotransplanted third molars during a mean follow-up period of 8.33 years. Rubber dam use is recommended during postoperative root canal treatment to improve the outcomes of auto-transplantation For successful root canal treatments, it is necessary to maintain the original configuration of the root canal system without causing any iatrogenic event, such as strip perforation. In this way, the assessment of the wall thickness along the canal axis is an essential aspect the canal contents. 1 Procedural accidents like perforation that occur during endodontic treatment can affect the long-term prognosis of the tooth. Root perforation is an artificial communication between the root canal system and the supporting tissues of a tooth or the oral cavity.2 Perforations in endodontics can occur during: • Access. Furcation perforation was found in two 6th year student cases, 0.2% of the total number of cases and 1% of all cases with iatrogenic errors. Strip perforation was seen in three 6th year student cases, 0.3% of the total number of cases and 1.2% of all cases with iatrogenic errors. Lateral root perforation was found in seven cases, three treate
