Sometimes pain originating from a non-odontogenic pathologic condition is mistaken as endodontic illness, leading to misdiagnosis. The patient can misinterpret the pain as originating from a site different from the actual site, which is known as referred pain. However, the clinician managing pain in the orofacial region needs to be well-informed about the typical signs and symptoms of non-odontogenic diseases and to be able to make the correct referral when necessary for proper diagnosis and treatment. A 43-year-old man presented to the department of conservative dentistry complaining of dental pain...

The antibacterial efficacy of intracanal medicaments for 2 and 7 days, in open apex root canals contaminated with Enterococcus faecalis biofilms was compared. One hundred and thirty-eight standardized uniradicular human roots were inoculated with E. faecalis. Colony forming units (CFU) were recorded before and after medication. Samples were divided in two (2/7 days), and subdivided (n=8/group): triple antibiotic paste (TAP); double antibiotic paste (DAP); dental base paste (DBP), consisting of calcium hydroxide, propylene glycol and calcium carbonate; DBP+0...

OBJECTIVE: The objectives of this study were to: (1) develop a bioactive endodontic sealer via dimethylaminohexadecyl methacrylate (DMAHDM), 2-methacryloyloxyethyl phosphorylcholine (MPC) and nanoparticles of amorphous calcium phosphate (NACP) for the first time; and (2) evaluate inhibition of early-stage and mature multispecies endodontic biofilm, bond strength to root canal dentin, and calcium (Ca) and phosphate (P) ion release. METHODS: A series of bioactive endodontic sealers were formulated with DMAHDM, MPC, and NACP...

Jun-Seong Park, Jeong-Sub Lee, Jeong-Won Park, Won-Gyun Chung, Eun-Hee Choi, Yoon Lee
STATEMENT OF PROBLEM: Post space size and cement thickness can differ because of variations in root canal morphology, such as an oval shape, and because the entire canal space cannot be included in the post space preparation. As a result, increased cement thickness around the post may affect the bond strength between the post and the dentin. PURPOSE: The purpose of this in vitro study was to evaluate the push-out bond strength of fiber-reinforced composite resin posts to root dentin with cement layers of varying thickness...

BACKGROUND: Vertical root fracture (VRF) is a diagnostic challenge for dentists. Cone-beam computed tomography (CBCT) scans provide accurate three-dimensional images of teeth enabling detection of VRFs. This in-vivo study compared the accuracy of CBCT and exploratory surgery for detection of VRFs in endodontically-treated teeth. METHODS: Forty endodontically-treated teeth of 40 patients with clinical signs and symptoms of VRFs were evaluated. No fracture line was detectable on periapical radiographs...

AIM: This retrospective study explored survival and periapical healing outcomes in root filled teeth with Thermafil obturators. METHODOLOGY: Root canals of 213 teeth (94 subjects, mean age 48±13 years), instrumented with a step-down technique, irrigated with 5% NaOCl and 10% EDTA and filled with Thermafil and AH-Plus sealer, were involved in a Recall programme. Teeth were retrospectively reexamined after 5±1 years in a controlled environment. Clinical and radiographic data that were collected included: preoperative Periapical Index (PAI) score and signs/symptoms, treatment type, root filling length and presence/absence of voids, restoration type, follow-up PAI score and signs/symptoms...

Veterinary dentistry has tended to follow the trends and advancements in the human dental field. As for any procedure performed on a patient, whether human or animal, an informed decision is based on the available evidence regarding treatment options. This is certainly true for the more involved treatments in veterinary dentistry which can include the disciplines of endodontics and dental implantology. A number of published case reports have been accepted by the specialty that endodontic therapy is indeed a predictable and a valuable service that can be offered to pet owners...

INTRODUCTION: To compare the cyclic fatigue of resistance of WaveOne (WO; Dentsply Maillefer, Ballaigues, Switzerland) and WaveOne Gold (WOG, Dentsply Maillefer) small, primary, and large instruments in simulated root canals. Each instrument was rotated until fracture occurred. METHODS: One hundred twenty nickel-titanium endodontic instruments were tested in two different curved artificial canals with different angles and radii of curvatures. WO and WOG small, primary, and large instruments were evaluated (n = 10 for each curvature)...

INTRODUCTION: We investigated the direct and residual antibacterial effects of intracanal antimicrobials against bacterial biofilms obtained from infected mature and immature teeth with necrotic pulps. METHODS: Sterile dentin slabs (n = 100) were inoculated with bacterial biofilms obtained from root canals of an immature or a mature tooth with pulpal necrosis and incubated anaerobically for 3 weeks (n = 50 per biofilm). Dentin infected with each type of biofilm received 1 week of treatment with 1 or 5 mg/mL double antibiotic paste (DAP) in methylcellulose hydrogels, calcium hydroxide, or placebo paste or received no treatment (n = 10)...

INTRODUCTION: The purpose of this study was to investigate the depths of penetration of a calcium silicate-based sealer in dentinal tubules by using 3 different obturation methods. METHODS: One hundred extracted human permanent anterior teeth were endodontically prepared and divided equally into 3 experimental groups and 1 control group as follows: CPoint single cone (CPSC), gutta-percha single cone (GPSC), gutta-percha vertical condensation (GPVC), all with a calcium silicate-based sealer and calcium indicator Fluo-3, and CPoint single cone with a calcium indicator Fluo-3 (CPF3) without sealer as the control...

INTRODUCTION: Stem cells are responsible for replacing damaged pulp tissue; therefore, promoting their survival and inducing their adhesion to dentin are vital. As a member of the Rho family of guanosine triphosphatases, Rac1 is an important regulator of osteoblast functions. However, little is known about its role in regenerative endodontic procedures. The current study examined the role of Rac1 in the proliferation, migration, and odontoblastic differentiation of MDPC-23 cells. METHODS: MDPC-23 cells were transfected with small interfering RNA to knock down Rac1 expression, and then their proliferation, migration, adhesion, and odontoblastic differentiation were examined in vitro...

OBJECTIVES: To evaluate the effect of restoration design ('2.5-mm deep endocrown', '5-mm deep endocrown' or '5-mm deep post&crown') and CAD/CAM material type (composite or lithium disilicate glass-ceramic) on the load-to-failure of endodontically treated premolars in absence of any ferrule. METHODS: The crowns of 48 single-rooted premolars were cut and the roots were endodontically treated. Teeth were randomly divided into six groups (n=8); teeth in each group were restored using one of the two tested materials with standardized CAD/CAM fabricated endocrowns (with either 2...

AIM: This randomized, double-blind, placebo controlled, clinical trial was designed to improve the success of inferior alveolar nerve blocks (IANB) in mandibular molars with symptomatic irreversible pulpitis (SIP) by means of pre-operative submucosal administration of 50mg tramadol. METHODOLOGY: Forty-two patients with a mandibular molar diagnosed with symptomatic irreversible pulpitis took part in the trial. Patients were assigned randomly to one of two groups: tramadol group (n=21), who received 50mg tramadol in 1mL by mandibular infiltration, and a placebo group (n=21), who received 1 mL of normal saline administered to the affected tooth by the same means...
