Introduction: The radiographic control of the root canal treatment can evaluate the healing of the periapical lesions. The objective of this study was to determinate the characteristics of the radiographic healing that was observed after one year, during follow-up sessions; so, the healing of the lesions according to the periapical pathology at the beginning of the treatment and the causes of failure of the endodontic treatments were recorded.Method: This is a prospective, observational, descriptive and longitudinal study, carried out in patients who attended control one year after endodontic treatment through the Periapical Index (PAI).Results: A total of 395 teeth of patients who underwent endodontic treatment one year prior to data collection, 87 presented radiogaphically observable periapical lesions; of these, 40 (45.97%) attended the control at one year. The frequency of cases in which some degree of radiographic healing was observed one year after treatment was 97.46%. The pathology with more cases of complete healing was periodontitis with sinus tract. In general, 84.61% of the cases decreased two levels in their PAI after one year. The 100% of the cases of failure presented vertical root fractures.Conclusion: The frequency of periapical healing after endodontic treatment is high. The main cause for the failure of the treatments documented in this study was the lack of coronal restoration that caused vertical fractures.

Background During the apexification procedure for teeth with open apices, mineral trioxide aggregate (MTA) may be unintentionally extruded. The aim of the present study was the retrospective evaluation of the healing of periapical lesions in permanent incisor teeth with open apices after the unintentional extrusion of MTA. Methods The clinical and radiographic records of 55 maxillary permanent central teeth treated by MTA apexification were evaluated. Filled teeth with unintentionally extruded MTA were selected as group 1 (n = 21), whereas the teeth with no MTA extrusion were selected as group 2 (n = 34). For each tooth, the clinical and radiographic records from a 3-year follow-up were investigated. Results Complete healing (CH) was observed in 19 teeth (90.4%) in group 1, whereas the same type of healing was observed in all 34 teeth (100%) in group 2 (p>0.05). At the 6-month follow-up appointment, 25 teeth (73.5%) showed CH in group 2, whereas 15 teeth (71.4%) showed CH at the 1-year follow-up in group 1 (p<0.001). At the end of the 3-year follow-up period, the amount of MTA extrusion was reduced in 17 teeth (85%) (p<0.05), whereas it was almost absent in 2 teeth (10%). Conclusions The unintentional extrusion of MTA does not prevent the healing of periapical lesions, but may be a delaying factor for periapical healing.

Introduction. Endodontic retreatment is a complex intervention that requires detailed analysis of possible reasons for failure, and flawless practical execution of the procedure. Objective. The aim of the study was to assess the outcome of endodontic retreatment based on clinical and radiographic criteria after a two-year observation period. Methods. Clinical study included 49 teeth indicated for endodontic retreatment based on periapical index (PAI). All teeth were divided into two groups. Group I comprised teeth without any periapical lesion (PAI score of 1 and 2) while Group II consisted of teeth with visible periapical radiolucency (PAI score of 3, 4, and 5). Endodontic retreatment was completed in two visits with inter-appointment medication of 2% chlorhexidine and calcium hydroxide for two weeks. Outcome of endodontic retreatment was evaluated 12-24 months after final obturation. Results. Endodontic retreatment was successful in 93.3% in Group I after 24 months. In Group II, successful treatment and complete healing was found in 52.9% of teeth, whereas 14.7% of teeth showed only partial healing. However, clinical symptomatology was not present in any of the cases. Considering the absence of clinical signs and subjective symptoms, retreatment was successful in 67.6% of cases where chronic periapical inflammation was present. Conclusion. Endodontic retreatment was successful in high percentage in teeth with and without periapical lesions.

Chronic apical periodontitis associated with dental pulp necrosis is the main cause of odontogenic extraoral cutaneous sinus openings. These tracts are often initially misdiagnosed unless the treating clinician considers a dental aetiology. This case report of a 19-year-old woman describes the diagnosis and treatment of an extraoral cutaneous sinus tract of odontogenic origin. Non-surgical conservative endodontic therapy was opted as the involved teeth were restorable. One month after the completion of obturation, there was closure of the sinus tract. One year follow-up showed complete resolution of the sinus tract with minimal scar formation.

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.

This study aims to report the clinical case of a 16 years-old male patient, who attended a private office reporting that at an accident suffered at the age of 10 years-old, which caused extrusive dislocation in both teeth 11 and 21. At that time, the teeth were repositioned, without an adequate follow-up. Upon physical and radiographic examination, the following features were observed: presence of recurrent sinus tract on the vestibular surface, area of ​​external cervical resorption, and a periapical lesion on tooth 21. Endodontic treatments (necropulpectomy) were performed on teeth 11 and 21, with the placement of a root canal dressing of calcium hydroxide and subsequent root canal filling. In addition, soft tissue flap folding was performed to treat the resorption area and to seal it with glass ionomer cement. A 7 months follow-up radiograph shows stabilization in the process of the tooth resorption and remission of the periapical lesion. In conclusion, the endodontic treatment with intracanal medication, and the sealing of the resorption area were successful to preserve the traumatized tooth. In addition, it is noteworthy that following up with the patient after the trauma episode is essential to monitor the pulp vitality of the tooth involved.

Pilonidal sinus in the intermammary region is a rare location of an inflammatory condition commonly occurring in the natal cleft. It is typically characterised by a pus and hair containing cavity in the skin lined by granulation tissue connecting the skin surface. A 22 year-old female presented with chronically discharging sinuses in the intermammary region with recurrent abscess formation for one year duration. Although a rare location, clinical diagnosis of pilonidal sinus was made. Complete excision of sinus tract with abscess cavity with primary closure was performed under general anaesthesia. Histopathological examination confirmed pilonidal sinus. On follow up, the scar was healthy with no keloid formation. Pilonidal sinus may rarely occur in intermammary region. Complete excision and primary closure is the mainstay treatment.
