Coronal rehabilitation of severely damaged endodontically treated teeth is the most challenging task as there is high risk of failure than vital teeth. Advances in adhesive dentistry have made great contributions to cosmetic & restorative dentistry over the past few decades. Endocrown is indicated for restoration of severely damaged molar, which requires specific restoration technique. This therapy promotes the stability and retention of the indirect restoration, without the need of a cast metal core or reconstruction with intracanal post, thereby reducing the treatment time. Endocrowns are formed from a monoblock containing the coronal portion integrated into the apical projection that fills the pulp chamber space and possibly the root canal ingresses. The major advantage of an endocrown is the use of the tooth structure remnant, particularly the pulp chamber, to promote retention and stability. This case report represents the restorations of severely damage mandibular molar teeth (46) by Endocrown which represented a conservative and aesthetic restorative alternative to full coverage crown. It was found that endocrown restorations could be made following the development of reinforced ceramics that can be acid etched, that have aggregate strength and esthetics, that bond to the dental structure, and that have developed from broader knowledge of the biomechanical behavior of depulped teeth restored with and without intraradicular posts. Clinical studies have shown that the endocrown has functional longevity, and has become a promising alternative in the esthetic and functional recovery of endodontically treated molar teeth.

The Impact

The aim of this case report is to present an innovative combined orthodontic-surgical technique to disimpact mandibular second molar (MM2) using an orthodontic miniscrew and an elastic chain. The impact on the Oral health-related quality of life (OHRQoL) was also evaluated. Using the present techinique, it is possible to expose the impacted tooth, insert a self-drilling miniscrew in the retromolar area, and remove the bud of third mandibular molar. At the same time the orthodontic force is applied with the use of an elastomeric chain that connects the head of miniscrew and vestibular and oral buttons bonded on MM2. A close traction is performed for the whole treatment time without the reactivation of the elastic force. The use of skeletal anchorage allowed the disimpaction of impacted MM2 in a short treatment time (about three months) avoiding the typical biomechanical side effects of traditional orthodontic appliance and increasing the effectiveness of the treatment. Further studies are necessary to evaluate the real advantages and disadvantages of this combined orthodontic-surgical approach.

Vertical root fractures of endodontically treated teeth are an exasperating complication that often leads to extraction of the tooth. Early detection and management of vertical root fractures, remain a vexing issue that has caused endless anguish for both the patient as well as the dental practitioner. Bicuspidization is a surgical procedure wherein the mesial and distal roots of primarily the mandibular molars are separated with their respective crown segments. This in turn helps the patient maintain effective oral hygiene by using an interdental brush, as it eliminates the presence of a furcation. This article elucidates the treatment procedure of a mandibular molar by biscuspidization.

Introduction: Denticles are mineralized formations found in the dental pulp of deciduous and permanent dentition. Topographically, they can be classified as free, adjacent, or intratissular. Denticles rarely occur; however, their presence is considered clinically relevant due to the difficulties they cause during endodontic treatment.The aim of this study was to describe clinical cases of denticles located in the tooth pulp chamber. Various methods for their removal are also discussed. Emphasis was placed on the diverse appearance of pulp stones in microscope-captured images and on the necessity of maintaining appropriate clinical proceduresfor highly specialized endodontic treatment, such as working with rubber dams and magnification, to avoid serious complications.Materials and methods: Four cases of molar teeth with suspected intraventricular denticles were subjected to specialised endodontic treatment. Removal procedures were performed in aseptic conditions after dental dam placement and with the use of a dental operative microscope. To remove denticles, carbide long shank rose burs, Munce Discovery Burs, and an ultrasonic device with tips for finishing canal access and locating their orifices were used. Following preparation of a straight line access, the canals were chemically and mechanically cleaned and shaped according to accepted standards of modern endodontics. After obturation of the canal system, control radiographs were performed. Results: During all treatments, the denticles were removed completely, allowing further preparation and obturation of the entire canal system.Conclusions: Removal of denticles from the pulp chamber is a complicated, difficult procedure, requiring knowledge of the anatomy of the root canal system, professional operation skills, magnification of the operating site, and appropriate equipment. Such preparation allows clinicians to avoid potential complications such as perforation and/or excessive weakening of the tooth structure due to excessive removal of hard tissues.

A common problem encountered by dentists is the restorative treatment of nonvital teeth. When the pulp chamber presents appropriate conditions for retention, the endocrown is indicated. This monolithic, ceramic adhesive restoration is singularly used yet warrants wider recognition and use. The endocrown allows preservation of the tooth structure and is minimally invasive. Currently, this treatment option, of a core buildup and full coverage restoration, reduces tooth structure excessively. This treatment presents not only functional limitations but also aesthetic concerns. Recently, the VITA-PM9 system, a leucite-reinforced glass ceramic, has been increasingly used in a variety of clinical situations due to its satisfactory physical-mechanical and aesthetic properties. Therefore, the present study describes a case of surgical restoration of a nonvital tooth using the endocrown technique and the VITA-PM9.

<p><strong> </strong></p><p><strong>Objective:</strong> The aim of this study was to investigate the effects of the short-term intracanal application of two medicaments on the fracture strength of root-filled molar teeth with different levels of tooth structure loss. <strong>Material and Methods:</strong> Standard access cavities of totally 84 intact maxillary molar teeth were prepared in 72 teeth and were divided into 3 main groups. Standard access cavities were kept in the first group, while mesio-occlusal-distal cavities (MOD) were prepared in the second and third groups. One-half of the palatinal walls were removed in the third group. Twelve sound teeth were used in the fourth group as control. Each group was then assigned into two subgroups according to the medicament used (n=12): 2% chlorhexidine gel and calcium hydroxide. Samples were stored at 37°C and 100% humidity for 1 week. Then the teeth were inserted into a universal testing machine and vertically loaded (5 mm/min) from the occlusal surface. The data was recorded in Newtons and statistically evaluated using a Univariate ANOVA and a Tukey as post hoc test. <strong>Results:</strong> A significant difference was found among the test groups (p&lt;0.01). No significant difference was found according to the medicament used (p&gt;0.05), however the number of remaining walls significantly affected the fracture strength (p&lt;0.01). The first group with access cavity showed mostly repairable fractures (60%–80%) whereas the others showed mostly non-repairable fracture patterns (60%–90%). <strong>Conclusion:</strong> In conclusion, the fracture strength of endodontically treated teeth is related to the structure loss rather than the intracanal medicament used.</p><p> </p><p><strong>Keywords</strong></p><p>Endodontically treated teeth; Fracture strength; Intracanal medicament; Remaining cavity wall; Root facture.</p>

Tooth Structure

Restoration of traumatic teeth with complicated crown root fracture poses many challenges to the clinicians. When the fracture line is below the level of gingiva, the prognosis of such fractured tooth is considered questionable or hopeless. Treating such cases is also challenging as they are associated with loss of ferrule and compromised biological width. Preservation of such diseased natural teeth usually involves a multi-disciplinary approach involving endodontic therapy, periodontal crown lengthening and / or orthodontic extrusion followed by prosthetic rehabilitation. Tooth injuries and complicated tooth fractures especially in the aesthetic region pose a great challenge to the clinician.1 When the fracture line extends at or below the level of cement enamel junction, the prognosis of such tooth is considered questionable or hopeless; they are usually associated with the loss of ferrule and compromised biological width, and therefore restoration of such teeth becomes a great challenge. To ensure functional longevity, endodontically treated teeth with less coronal structure must have at least 5 mm of tooth structure coronal to the crestal bone. Three milli meters of tooth structure is needed to maintain a healthy soft tissue complex, and 2 mm of coronal tooth structure incisal to the preparation finish line is necessary to ensure structural integrity.2 There are mainly two reasons why a tooth extraction should be avoided: Structural reasons and psychological stress associated with extraction. Psychological stress can be in the form of financial stresses associated with extraction and rehabilitation of the same and fear of post-traumatic pain. Extraction of tooth is also followed by aesthetic challenges as it may lead to hard and soft tissue resorption as the healing architecture is unpredictable. In this case report a simple yet effective treatment is presented for a 21-year-old female patient with a chief complaint of clinical tooth fracture in relation to 44. After thorough clinical and radiographic examination, it was decided to reinforce the use of flexible glass fibre post and incorporate the same as tags to engage E chain to facilitate orthodontic tooth extrusion followed by prosthetic rehabilitation. The purpose of this case report is to describe the use of a simple chair side technique for a tooth fractured at the level of cementoenamel junction (CEJ) with forced tooth eruption.

Coronal fractures of the anterior teeth arising after endodontic treatment are sequelae of dental trauma. Endodontically treated teeth presents a higher risk of biomechanical failure than vital teeth. Posts are needed for restoring teeth with insufficient coronal tooth structure to retain a core for definitive restoration. Fiber posts are more easily and safely removed "by hollowing them out from the inside”. This present case report depicts a 23 year old male patient with fracture of tooth number 21 which had undergone an RCT 8-10 months ago and was restored using fiber post.

Abstract This study evaluates the amount of remaining tooth structure and possibility of producing lateral perforation following the use of different diameters of parallel-sided Parapost drills in groups of different canal curvatures (0〬-15°, 16°- 25°, 26°<) in distal canals of first and second mandibular molar teeth. After enlargement of root canals using the crown-down pressureless technique, Parapost drills #1, #2, and #3 were used in the different canal groups for the preparation of a post space. Standardized digital radiographs were taken before the post space preparation and after each Parapost drill application. Four horizontal lines (a, b, c, and d) were drawn at equal distances on these images, starting from the pulp chamber floor moving apically at 2 mm increments. There were no significant differences between the different curvature groups at the a, b, c, and d levels for the critical level of the remaining tooth structure (multiple comparison test; p>0.05). However, in considering root perforation, both at the inner and outer side of the roots, there were statistically significant differences at “c” and “d” levels in group 3 (#3 drill) without taking into account the root curvature (ANOVA; p<0.5). None of the specimens showed strip perforation. Citation Tinaz AC, Alaçam T, Topuz Ö, et. al. Lateral Perforation in Parallel Post Space Preparations. J Contemp Dent Pract 2004 August;(5)3:042-050.
