Most of periapical lesions usually result from microbial infection with oral microorganisms originating from the degenerated pulp tissue. These lesions are commonly painless and incidentally found on routine radiographic examinations. Treating these cases using non-surgical root canal is the fruit of the innovative techniques, tools and root medicaments as well as the tendency toward minimally invasive treatment. The healing process of the infected area is conditioned by a proper diagnosis, a treatment that follows good clinical practice under aseptic environment including cleaning, shaping and root filing. The aim of the present clinical case report was to report non-surgical healing of a periapical lesion of endodontic origin associated with maxillary left central incisor, observed over a period of 2 years.

Triple Antibiotic Paste

Sterilization of root canal space is foremost for the success of the endodontic treatment which is usually carried out with intracanal irrigants and medicaments. Triple antibiotic paste (metronidazole, ciprofloxacin, and minocycline) is used to achieve sterilization and healing of periradicular area. In the present case report, the triple antibiotic paste was used for non-surgical management of periapical lesion for 3 weeks. After 3 weeks, the tooth became asymptomatic that was then obturated. Hence, it is confirmed that conventional root canal treatment, along with intracanal medicaments (triple antibiotic paste), can non-surgically manage the periapical lesions and further promotes healing.

Root Apices

Pulpal and periradicular pathosis are the result of microbial, mechanical, or chemical invasion. Microorganisms are the main irritants of pulpal and periapical tissues. The goal of the obturation is to obtain a fluid-tight seal of the root canal system from its coronal aspect through its apical extent to preserve from the irritants.. Root apices have morphological irregularities in teeth with periapical lesions. Therefore, it is more difficult to produce hermetically apical stop with conventional guttapercha obturation techniques. This case report describes the treatment and six years follow-up of the teeth with large periapical lesion using MTA as apical filling material. (Eur J Dent 2010;4:468- 474)

O objetivo deste trabalho é relatar um caso clínico de uma extensa lesão periapical em maxila, tratada somente por uma abordagem endodôntica não cirúrgica, com expressivo reparo periapical. Paciente do sexo feminino, 52 anos, compareceu à clínica odontológica, com a queixa principal de “cisto crescendo na boca”. Os dentes 13, 14 e 15 apresentavam-se sem vitalidade pulpar. Os exames radiográficos mostraram duas áreas radiolúcidas, uniloculares, envolvendo os ápices dos dentes 13 e 15, ambos sem sinais de intervenção endodôntica. As áreas eram sugestivas de granuloma periapical e cisto periapical inflamatório, respectivamente. Realizou-se tratamento endodôntico dos dentes 13, 14 e 15. Após 11 meses, notou-se regressão significativa da rarefação óssea periapical, não sendo necessária qualquer intervenção cirúrgica. A paciente continuará em proservação até a remissão completa da lesão. O preparo químico-mecânico, associado ao emprego de medicação intracanal, pode ser suficiente para o reparo de lesões periapicais extensas. Sugere-se que o tratamento conservador seja sempre a primeira opção em casos semelhantes, de forma a se evitar cirurgias parendodônticas invasivas desnecessárias.

Traumatic injuries to an immature permanent tooth may result in cessation of dentin deposition and root maturation. Novel revascularisation endodontic procedure (REP) has been considered as an option for treatment of immature teeth with damaged pulp tissue. The continuous development of the root and the root canal has been recognised as a major advantage of this technique over traditional apexification approach. Traditional apexification procedures may resolve pathology but have not been able to prove tooth survival due to absence of continued root development and risk of root fracture. A successful REP results in resolution of signs and symptoms of pathology, radiographic signs of healing, proof of continued root development as well as presence of pulp vitality due to the regeneration of pulp tissue in the root canal. Currently, repair rather than true regeneration of the ‘pulp-dentine complex’ is achieved and further root maturation is variable. According to Glossary of Endodontic terms published by American Association of Endodontists, REP’s are biologically based procedures designed to physiologically replace damaged tooth structures, including dentin and root structures, as well as cells of the pulp-dentin complex.1,2 Apexification treatment has been a routine procedure to treat and preserve such teeth for many decades.3 Apexification is the process by which a suitable environment is created within the root canal and periapical tissue to allow for the formation of a calcific barrier across the open apex. Calcium hydroxide [Ca(OH)2] has been the material of choice for apexification as Frank reported its capacity to induce physiological closure of immature pulpless teeth in 1966.4 However, this technique has several disadvantages, including the unpredictability of apical barrier formation and the long duration of treatment, which often requires multiple visits.5 A retrospective study by Jeruphuaan et al.6 has shown a higher survival rate with regenerative endodontic treatment when compared to both mineral trioxide aggregate (MTA) and Ca(OH)2 apexification. The first evidence of regeneration of dental tissues was in 1932 by G.L. Feldman, who showed evidence of regeneration of dental pulp under certain optimal biological conditions.7 In 1971, a pioneer study in regenerative endodontics conducted by Nygaard-Ostby concluded that bleeding induced within a vital or necrotic canal led to resolution of signs and symptoms of necrotic cases and in certain cases, apical closure.8 According to Windley et al. (2005), the successful revascularisation of immature teeth with apical periodontitis is mainly dependent upon: 1. Canal disinfection 2. Scaffold placement in the canal for the growing tissues 3. Bacteria-tight sealing of the access opening.9 The purpose of this case report is to illustrate the outcome of a revascularisation endodontic procedure in a non-vital immature young permanent central incisor.

Introduction: The present study sought to assess the effect of apical foramen cleaning in the repair of periapical lesions detected by radiography. Methods: The sample comprised 980 teeth collected from 25 February 1997 to 15 March 2005 which had been subjected to endodontic treatment and exhibited radiographically visible periapical lesions. The sample was then divided into two groups: Group I, 402 root canal treatments in which cleaning of the apical foramen had not been performed, and Group II, composed of the remaining 578 root canal treatments where the procedure had been performed. After one year, the teeth were clinically and radiographically evaluated. Results: In Group I, 360 canals (89.55%) had no evidence of periapical lesions, versus 521 (90.13%) in Group II. Partial presence of these lesions was observed in 23 canals (5.72%) in Group I versus 27 (4.67%) in Group II. No changes in images were observed in 19 (4.72%) canals in Group I and 30 in Group II. Pearson’s chi-square test showed no statistically significant difference between the Groups I and II (p = 0.732). Conclusions: These findings suggest that foramen cleaning is not a determinant of periapical lesion repair.

The C-shape configuration in molars it’s an anatomical variation that difficult the diagnosis and treatment. The aim of this study was to report a case of C-shape endodontic configuration in mandibular second molar. The radiographic examination of one patient revealed the extent of caries in the mesial aspect of mandibular second molar, without the presence of periapical lesion and was clinically noted the C-shape configuration of the root canal, extending from the mesiobuccal to the distal canal. Endodontic therapy was performed and after the root canal obturation with gutta-percha cones and endodontic cement the tooth was restored. We conclude that the anatomical condition in C-shape, although it brings many difficulties for the endodontic treatment, does not preclude the tooth rehabilitation.

ABSTRACT Introduction A thorough knowledge of the anatomic morphology of the root canal system is necessary for the long-term success of the root canal therapy. The occurrence of C-shaped root canal configuration is one such variation. Achievement of favorable prognosis after commencing root canal therapy in such teeth is one of the challenges imposed on the endodontist. Hence, we evaluated the healing occurring after endodontic therapy in patients with C-shaped root canals in mandibular molars. Materials and methods The present study was conducted in the Department of Conservative Dentistry of the institution and included assessment of all the patients who underwent root canal treatment of the mandibular first and second molars. Endodontic therapy was performed in all the cases by experienced endodontist. Final postoperative radiographs were taken. Recording of the data of the personal and clinical details of a total of 250 patients was done. All the clinical and radiographic details of the patients, such as tooth location in the jaw, presence or absence of C-shaped canals, status of the pulp tissue, presence or absence of the fractures, and other details of the patients were recorded. Radiographic and clinical examination of the tooth of the patients was done during the baseline visit and further during the follow-up visits. The presence of C-shaped root canals was confirmed using the radiographs. Periapical index (PI) scoring system was used. Categories defined for enlisting the healing after the root canal treatment with the assessment of the PI score. All the results were analyzed by Statistical Package for the Social Sciences software. Results Vital pulp tissue was encountered in majority of the cases. C-shaped root canal configuration was observed in 40% of the cases included in the present study. After completion of the endodontic therapy, complete crown placement was done in only 22% of the cases. In cases of vital teeth with C-shaped root canals configuration, most of the teeth showed complete healing. Significant results were obtained while comparing the complete coverage crown parameter in relation to the healing process in teeth with C-shaped root canals. Conclusion In the present study, no significant effect of the C-shaped root canal configuration was found on the healing rate of the endodontic therapy in mandibular molars. Clinical significance Meticulous endodontic therapy with special techniques should be done while preparing teeth with C-shaped root canals.

Dental traumatic injuries may affect the teeth and alveolar bone directly or indirectly. Pulpal necrosis and chronic and apical periodontitis with cystic changes are the most common sequelae of the dental traumatic injuries, if the teeth are not treated immediately. This case report focuses on the conventional and surgical management of mandibular central incisors. A twenty-four-year-old male patient presented with pain in the mandibular central incisors. Radiographic examination revealed mandibular central incisors with dumbbell shaped periapical lesion. After root canal treatment, parendodontic surgery was performed for mandibular central incisors. After one-year recall examination, the teeth were asymptomatic and periapical lesion had healed.

Gigi premolar maksila merupakan gigi yang mendapat tekanan pengunyahan besar dan rentan mengalami fraktur terutama setelah dilakukan perawatan saluran akar (PSA). Gigi yang telah dilakukan PSA akan menjadi sangat rapuh dan rentan fraktur karena telah kehilangan kelembaban dan banyak jaringan kerasnya. Gigi premolar juga mendapat tekanan pengunyahan yang besar karena bentuk dan letaknya yang lebih dekat dengan aksis horizontal transversal. Penggunaan parallel self-threading dowel dan mahkota penuh porselen fusi metal akan mendistribusikan beban pengunyahan keseluruh bagian akar dan meningkatkan ketahanannya terhadap fraktur. Tujuan laporan kasus ini adalah untuk menunjukkan keberhasilan penggunaan parallel self-threading dowel dengan mahkota penuh porselen fusi metal sebagai restorasi pasca PSA pada gigi premolar kedua maksila nekrosis pulpa dengan lesi periapikal. Pasien wanita berusia 30 tahun dirujuk untuk PSA pada gigi premolar kedua kanan maksila nekrosis pulpa dengan lesi periapikal. Pasien merasakan sakit saat gigi digunakan untuk makan. Perkusi dan palpasi positif namun mobilitas normal. Pemeriksaan radiografik menunjukkan gambaran radiopak yang telah mengenai ruang pulpa dan radiolusensi pada periapikal gigi. PSA dan restorasi mahkota penuh dilakukan dengan parallel self-threading dowel. Parallel self-threading dowel dan mahkota penuh PFM sebagai restorasi akhir menunjukkan keberhasilan perawatan pada gigi premolar kedua maksila pasca PSA. ABSTRACT: Porcelain Fused to Metal Crown with Parallel Self-Threading Dowel Post Root Canal Treatment On Maxillary Premolar. Maxillary premolar teeth have great chewing forces and prone to fracture, especially after root canal treatment (RCT). Teeth that have RCT done will be very brittle and fracture prone because it has lost moisture and lost most of its hard tissue. Premolars also receive great chewing forces because its shape and location are closer to the horizontal transverse axis. The use of parallel self-threading dowel and full porcelain fused to metal crowns will distribute the load of mastication throughout the roots and improve resistance to fracture. The aim of this case report was to demonstrate the success of the use of parallel self-threading dowel with full porcelain fused to metal crown restoration aftera RCT on maxillary second premolar with pulp necrosis and periapical lesion. A 30-year-old female patient was referred for RCT on the maxillary right second premolar with pulp necrosis and periapical lesion. Patient felt pain when the tooth was used to eat. There was tenderness to percussion and palpation but the mobility was normal. A radiographic examination showed radiopaque image that entered pulp chamber and periapical radiolucency on tooth. RCT and full crown restoration with parallel self-threading dowel had been performed. Parallel self-threading dowel and full porcelain fused to metal crown as the final restoration after RCT on the maxillary second premolar showed a successful treatment outcome.

Introduction. Periapical inflammatory lesions are local bone responses around the apex of a tooth that occur after necrosis of the pulp tissue. The ultimate goal of reconstructive surgical techniques in the treatment of the intra-bone defects is a regeneration of lost bone tissue. The aim of this report was to evaluate clinical and radiographic outcome following the removal of two big, periapical lesions, approximately of the same size, located around maxillary lateral incisors, in the same person at the same time, using two different regenerative approaches. Case report. A healthy, 21-year-old female presented with two large periapical lesions around both upper lateral incisors, and a surgical treatment was indicated. One residual defect (tooth #12) was filled with the mixture of bovinederived hydroxyapatite xenograft and platelet rich fibrin (PRF) gel and covered with PRF membrane, while the other (tooth #22) was filled with bovine-derived hydroxyapatite xenograft only and covered with a resorbable collagen membrane. Clinical and radiographic examinations were performed seven months after the surgery. All clinical and radiographic parameters were significantly improved after the treatment on both sites; however, a newly formed bone around the tooth 12 showed a higher bone density. Conclusion. The use of PRF significantly speeded up filling of the defect compared to bovine- derived hydroxyapatite xenograft.
