Abstract Background: To investigate the changes of Schneider membrane thickness by CBCT pre and post root canal treatment, retreatment and pulp capping procedures. Methods: This retrospective study was conducted on CBCT scans of a patient population of Guy’s Hospital NHS Foundation Trust, London. Three groups of patients were studied: Group 1 consisted of patients referred for primary endodontic treatment; Group 2 for endodontic retreatment; Group 3 for indirect pulp capping procedures (serving as a control group). Follow up scans were carried out 1 year after treatment. Measurements were carried out on CBCT scans and data were analysed statistically by Wilcoxon Signed Rank Test. Linear regression was used to assess predictive parameters for membrane thickness. Results: A statistically significant reduction of the Schneider membrane thickness was observed one year after endodontic treatment and retreatment (P<0.05) but no significant reduction was observed after pulp capping procedures. Linear regression showed that age and gender were significant predictors influencing the Schneider membrane thickness. Conclusions: Within the limitations of this retrospective study, following root canal treatment and re-treatment a Schneiderian membrane thickness reduction occurred at 1-year follow-up. The removal of odontogenic infection following endodontic treatment may help reducing the thickness of the Schneider membrane. Trial registration: Ethical approval and registration were granted by the NRES London Bridge and Dulwich Research Ethics Committee. TRN NCT03055975

Endodontic treatment of two maxillaryincisors with dens invaginatus is reported. Invaginated teeth present technical difficulties with respect to their management because of complicated canal morphology. This case was treated by conventional root canal treatment. The signs and symptoms ceased after the treatment. At follow up examination after 18 and 20 month the teeth were asymptomatic and radiographically showed sound periodontal and periapical tissue.

Clinical evaluation for a successful root canal treatment is assessed by various criteria, which are clinical, histopathological, and radiographical criteria. Therefore, failure of endodontic treatment can be described as a recurrence of clinical symptoms, with the presence of a periapical radiolucency or both. Failure factors in the treatment are frequently related to persistent infection. Conventional endodontic retreatment is indicated for symptomatic previously treated teeth or asymptomatic teeth with inadequately done initial endodontic treatment to avoid potential recurrence. Endodontic retreatment in elderly patients is a great challenge because the clinician has to reassure both the physical and psychological factors of the patient to determine whether to save a tooth or perform an extraction. Some difficulties may also be found in root canal retreatment, including finding the root canal hole or root canal blockage found in parts of the root canal that have not been repaired in the previous treatment. A 60-year-old female patient came with the chief complaint of recurrent pain, and subjective discomfort in the maxillary left central incisor. The patient had anxiety about the dental treatment. The tooth had a history of root canal treatment four months ago. The clinical examination showed a positive response to the percussion test. The radiographical analysis showed a root canal underfilling, 2-3 mm short of length from the apex. The tooth was diagnosed as a previously treated tooth with symptomatic apical periodontitis. Endodontic retreatment was performed based on the patient’s clinical condition and consent, followed by composite restoration. The clinical and radiographic re-evaluation after four weeks of follow-up revealed an excellent condition. This favorable result showed that a conventional retreatment plan of persistent pain on the previously treated tooth in an elderly patient led to progressive healing, and a longer follow-up was advised.

Purpose: This retrospective study evaluated the survival rates of implants compromising adjacent teeth and the associated complications. Methodology: Medical records and orthopantomographic images of 1,132 patients and 1,478 implants were retrospectively analyzed. Finally, 96 patients (52 females, 44 males) with 111 malpositioned implants were included in the study. The mean follow-up of the study was 32 ± 14 months. The patients were divided into two core groups: 1) adjacent teeth and dental implants were considerably close but tangent to each other (TAN), and 2) dental implant cutting the roots of the adjacent tooth (CUT). In addition, the CUT group was divided into two subcategories considering the possible cause of malangulation as angled implant (AI) or angled adjacent tooth (AT). Damage to adjacent teeth, future treatment requirements, and the survival rates of the implants were recorded. Results. Among the 111 implants, 4 (3.6%) implants failed, all of which belonged to the CUT category and the AI subgroup. Among the 88 preoperatively vital adjacent teeth, root canal treatment was performed in 18 (20.5%) teeth, whereas 2 (2.3%) teeth were extracted due to malpositioned implanting in follow-ups. Conclusions. The placement of implants too close to the adjacent teeth and even cutting direction did not have a statistically significant effect on the survival rates of implants. However, this could cause adjacent teeth to undergo unnecessary root canal treatment or extraction. Clinical relevance. Patients with malpositioned adjacent teeth or dilacerated root(s) adjacent to the edentulous area are at a higher risk for malpositioned implant complications. Most implant malposition complications are observed in the first premolar region (37% cases). Therefore, more attention should be given while placing implants in the first premolar region.

Dens invaginatus is a rare malformation of the teeth resulting from the invagination of the tooth crown before biological mineralization occurs. In most cases, the thin or incomplete enamel lining of the invagination cannot prevent the entry of bacteria into the pulp, which leads to pulp necrosis with an eventual periapical inflammatory response. The treatment options include preventive sealing or filling of the invagination,root canal treatment, endodontic apical surgery and extraction. The root canal treatment of such teeth is often complicated because of their anatomical complexity. This case describes a successful non-surgical endodontic treatment of a maxillary lateral incisor with type 2 dens invaginatus with a large periradicular lesion. At follow-up examinations after 6 and 12-months, the tooth was asymptomatic and the healed lesion was evident radiographically.

Background Reciproc instruments are the only contemporary root canal instruments where glide path preparation is no longer strictly demanded by the manufacturer. As the complete preparation of root canals is associated with success in endodontic treatment we wanted to assess the ability and find predictors for Reciproc instruments to reach full working length (RFWL) in root canals of maxillary molars in primary root canal treatment (1°RCTx) and retreatment (2°RCTx) cases. Methods This retrospective study evaluated 255 endodontic treatment cases of maxillary molars. 180 were 1°RCTx and 75 2°RCTx. All root canals were prepared with Reciproc instruments. The groups were compared and in a binary logistic regression model predictors for RFWL were evaluated. Results A total of 926 root canals were treated with Reciproc without glide path preparation. This was possible in 885 canals (95.6%). In 1°RCTx cases 625 of 649 (96.3%) canals were RFWL and in 2°RCTx cases 260 of 277 (93.9%). In second and third mesiobuccal canals (MB2/3) 90 out of 101 (89.1%) were RFWL with Reciproc in 1°RCTx and in the 2°RCTx treatment group 49 out of 51 cases (96.1%). In mesio-buccal (MB1) canals “2°RCTx” was identified as negative predictor for RFWL (OR 0.24 (CI [0.08–0.77])). In MB2/3 canals full working length was reached less often (OR 0.04 (CI [0.01–0.31])) if the tooth was constricted and more often if MB2/3 and MB1 canals were convergent (OR 4.60 (CI [1.07–19.61])). Discussion Using Reciproc instruments, the vast majority of root canals in primary treatment and retreatment cases can be prepared without glide path preparation.

In this study, 120 teeth having periradicular pathosis were treated with single visit root canal treatment and then obturated with either calcium hydroxide containing sealer or mineral trioxide aggregate based sealer. The healing of periradicular pathosis was examined at 3, 6, and 12 months by clinical and radiological evaluation. Collected data were analyzed with standard statistical methods by using SPSS version- 20. The results showed that at 3 and 6 months, the differences between calcium hydroxide containing sealer or mineral trioxide aggregate based sealer were not statistically significant. However, the healing capability of periapical radiolucency at 12 months between two groups was statistically significant (P=0.03). The final outcome of the clinical and radiological investigation showed successful results of 96.6% and 98.1% in calcium hydroxide and mineral trioxide aggregate group, respectively. In conclusion, both calcium hydroxide and mineral trioxide aggregate based sealers are almost equally effective in single visit root canal therapy for the management of periradicular pathosis.
