Objectives: The aim of this study was to assess the prevalence of periapical lesions in root canal-treated teeth in a Turkish Cypriote population and to investigate the influence of the quality of root canal fillings and coronal restorations on the prevalence of periapical lesions.
Subjects And Methods: The sample for this cross-sectional study consisted of 1,006 adult patients seeking routine dental care. Patients who had received dental care in the last 2 years were excluded. Radiographs of 2,200 root canal-treated teeth were evaluated. The teeth were grouped according to the radiographic quality of the root canal filling and the coronal restoration. Periapical status was assessed using periapical index (PAI) scores.
Results: Of the 2,200 root canal-treated teeth, 1,364 (62%) had apical periodontitis as compared with 1,364 (5.5%) of the total sample. Root-filled teeth classified as adequately treated had apical periodontitis in 223 (26.6%) cases compared with 1,192 (87.7%) in teeth classified as inadequately root filled. PAI 1 scores of adequate root canal treatment were significantly higher than in inadequate root canal treatment, regardless of the quality or presence of coronal restorations (p < 0.01).
Conclusion: Our findings showed a high prevalence of periapical pathology with or without endodontic treatment and poor technical standard of both root fillings and coronal restorations of root-treated teeth. Hence, we suggest the need for better education for dental health providers so that they can perform better root canal treatments and coronal restorations.

Background: The aim was to evaluate the stresses in teeth, with external root resorption (ERR) restored with different materials using finite element analysis (FEA).
Methods: In this study, a Micro-CT scan was conducted on a prepared maxillary central tooth. DICOM-compatible images obtained from the sections were converted into stereolithography format using Ctan software.

Purpose: Functional alignment (FA) in total knee arthroplasty (TKA) prioritizes soft tissue balancing and anatomical restoration without systematic correction to neutral alignment. Most studies have focused on varus deformity, with little evidence available about FA in valgus deformity. The hypothesis of the present study was that FA in robotic-assisted TKA for valgus deformity would demonstrate correction of the coronal alignment and yield satisfactory short-term outcomes.

Background/purpose: Selecting an appropriate coronal restoration after root canal treatment requires careful consideration, however, there is a lack of established web-based tool that is based on clear guidelines for suitable post-endodontic restorations. Hence, we aimed to design and determine the acceptability of an interactive application to aid the decision making process for post-endodontic restoration among the undergraduate dental students.
Materials And Methods: A web-based post-endodontic restoration decision making interactive application, ( was developed after a detailed review of available literature.

Objectives: The aim of this non-interventional, multi-center, prospective, practice-based study was, firstly, to evaluate the longevity of composite build-ups in endodontically treated teeth, treated with root canal therapy (ETT), without post placement and secondly, to identify and analyze factors influencing the success of these reconstructions.
Methods: Each of seven general dental practitioners placed up to 50 composite build-ups without additional posts in ETT. Teeth were restricted to incisors, canines and premolars.
