OBJECTIVE: Intentional replantation (IR) is considered as a viable treatment option to preserve the teeth with apical periodontitis. This study aimed to compare the treatment outcomes of IR in teeth with or without periodontal involvement, and to investigate the influence of related factors. METHODS: A total of 157 teeth with a documented history of IR between September 2012 and November 2022 and a follow-up duration of more than 1 year were included. The samples included 100 teeth with simple apical periodontitis and 57 teeth with combined periodontal-endodontic lesions (CPEL)...

INTRODUCTION: In an effort to enhance the quality of mechanized endodontic instruments, various thermal treatment methods and design modifications have been suggested. However, upon evaluation, these endodontic instruments may exhibit microscopic irregularities. The objective of this in vitro study was to analyze the cutting capacity, surface finish, and mechanical properties of NiTi 25/.04 Rotate (VDW GmbH, Munich, Germany) and Logic 2 (Easy Equipamentos Odontológicos, Belo Horizonte, MG, Brazil) rotary instruments...

INTRODUCTION: Autoimmune liver diseases (ALDs) are chronic conditions generated by an immune-mediated auto-aggressive inflammatory reaction in genetically susceptible individuals. The purpose of this study was to evaluate the prevalence of AP in patients suffering from ALDs, in treatment with the immune-suppressants glucocorticoids, azathioprine, and/or ursodeoxycholic acid. METHODS: The ALDs group included 46 patients (11 men and 35 women, average age: 57.9 ± 11...

INTRODUCTION: The aim of this study was to investigate the feasibility of a real-time three-dimensional dynamic navigation system (3D-DNS) for root post space preparation (RPSP) in root canal-treated teeth and compares the accuracy and efficiency of 3D-DNS to freehand (FH) for RPSP. METHODS: Fifty-four maxillary molars were divided into two groups: 3D-DNS (n = 27) and FH group (n = 27). Cone beam computed tomography (CBCT) scans were taken pre- and post-operatively...

INTRODUCTION: Orthognathic surgery has the potential to compromise the vitality of the teeth. This paper aims to assess changes in pulp blood flow (PBF) and pulp sensibility (PS) of the anterior dentition following orthognathic surgery and to assess the influence of the proximity of the surgical osteotomy on the PBF and/or PS. METHODS: Twenty-six patients undergoing orthognathic surgery (Le Fort I or bilateral sagittal split osteotomy BSSO) were compared to sixteen control patients treated by fixed appliances only using Laser Doppler flowmeter (LDF) and thermal testing (CO2 snow)...

INTRODUCTION: Information concerning the anatomy of the physiological foramen is still limited. The aim of this study was to investigate the distance between the physiological and anatomical apex, the shape and diameter of the physiological foramen in maxillary (Mx) and mandibular premolars (Mn). METHODS: The anatomy of the apex of 229 maxillary (first: MxP1; second: MxP2) and 221 mandibular premolars (first: MnP1; second: MnP2) from a mixed Swiss-German population was investigated by means of micro-computed tomography and 3D software-imaging...

INTRODUCTION: The aims were to investigate 1) the frequency of nonsurgical retreatment, root-end surgery, extraction, and further restorative treatment during a follow-up of 10 to 11 years after root filling and compare the frequencies according to tooth group and type of coronal restoration, and 2) the timing of nonsurgical retreatment, root-end surgery, and extraction. METHODS: Data were collected from the Swedish Social Insurance Agency's register. A search for treatment codes identified teeth root filled in 2009 and the type of coronal restoration (direct, indirect, unspecified) registered within 6 months of root filling...

INTRODUCTION: Chronic inflammation in irreversible pulpitis leads to heightened sensitivity of nociceptive receptors, resulting in persistent hyperalgesia. This poses significant challenges in achieving effective anesthesia for patients with irreversible pulpitis. Various anesthetic techniques and pharmacological approaches have been employed to enhance the success of local anesthesia. Recently, the preemptive use of anti-inflammatory agents, specifically corticosteroids, has gained attention and shown promising results in randomized controlled trials...

INTRODUCTION: Large scale clinical studies on the incidence of middle mesial canals (MMCs) in non-surgical root canal treatment and retreatment of mandibular molars are lacking. The primary aim of this observational study was to determine the incidence of MMCs in mandibular first and second molars that received root canal treatment (RCT) or non-surgical retreatment (NSRetx). The secondary aim was to determine factors associated with incidence of MMCs. METHODS: Included were 3,018 mandibular molars that received RCT (n=1,624) or NSRetx (n=1,394) by three Endodontists in a private practice...

INTRODUCTION: In endodontic treatment, it is important to remove or inactivate biofilms in the root canal system. We investigated the effects of different concentrations and application times of sodium hypochlorite (NaOCl) on the viability of bacteria in ex vivo polymicrobial biofilms of different maturation levels. METHODS: Polymicrobial biofilms were prepared from dental plaque samples and grown for 1, 2, and 3 weeks under anaerobic conditions on collagen-coated hydroxy apatite discs as an ex vivo biofilm model...
