Pulp Survival of Cracked Teeth with Reversible Pulpitis after Orthodontic Banding and Coronal Coverage - A Prospective Cohort Study with One Year Follow Up.

Introduction: The aim of this prospective study was to investigate the 1-year pulp survival of cracked teeth with reversible pulpitis managed with initial stabilization using orthodontic bands, followed by coronal coverage restorations.

Methods: One-hundred-and-twenty-five patients with a cracked tooth with reversible pulpitis each were recruited. Preoperative patient and tooth data were collected.

Characteristics of Cracked Teeth with Reversible Pulpitis After Orthodontic Banding-A Prospective Cohort Study.

Introduction: Cracked teeth with reversible pulpitis can be managed with orthodontic bands in the interim before definitive restorations. The aim of this study was to determine short-term outcomes of these teeth following orthodontic band placement. The time taken for definitive pulp diagnoses after orthodontic band placement and associated prognostic factors was also analyzed.

Psycho-social perspectives of nonsurgical versus surgical endodontic interventions in persistent endodontic disease.

Introduction: Patients' experiences related to dental treatment could influence care-seeking behaviour and engender personal bias. Although endodontic retreatment and apical surgery are procedures often performed to manage previously treated teeth with persistent disease, there is lack of information regarding psycho-social perspectives of patients who undergo these treatments. Our aim was to compare experiences of patients who received these two treatment modalities using a qualitative approach.

Management of cracked teeth: Perspectives of general dental practitioners and specialists.

Objectives: The main aim of this study was to compare how general dental practitioners (GDPs), endodontists and prosthodontists diagnose, prognosticate, and treat cracked teeth. The secondary aim was to highlight factors influencing GDPs' referral practices of cracked teeth to specialists.

Materials And Methods: Questionnaires were used to collect information from GDPs, prosthodontists, and endodontists, on their use of diagnostic methods to identify cracked teeth, prognostication, and their management and referral practices for cracked teeth.

Postobturation Pain Associated with Tricalcium Silicate and Resin-based Sealer Techniques: A Randomized Clinical Trial.

Introduction: The incidence of immediate postobturation pain associated with 2 sealer techniques was compared and potential prognostic factors identified.

Methods: Patients referred for endodontic treatment were recruited with informed consent. Root canals were debrided and teeth rendered asymptomatic before random allocation to receive TotalFill BC (FKG Dentaire SA, La Chaux-de-Fonds, Switzerland) or AH Plus sealer (Dentsply Maillefer, Ballaigues, Switzerland).

Factors Influencing Quality of Life after Surgical and Nonsurgical Interventions of Persistent Endodontic Disease.

Introduction: Nonsurgical endodontic retreatment and apical surgery are predictable procedures for the management of endodontically treated teeth with persistent disease. However, there is no information available that compares these treatment modalities based on patients' oral health-related quality of life (OHRQOL). The aims of this study were to compare the OHRQOL of patients who received nonsurgical endodontic retreatment versus those who received apical surgery and to identify correlations between OHRQOL, clinician-assessed healing outcome, and other factors.

An Immunofluorescence Study to Analyze Wound Healing Outcomes of Regenerative Endodontics in an Immature Premolar with Chronic Apical Abscess.

Introduction: Limited studies have examined tissue formation via immunofluorescence in regenerative endodontic procedures (REPs) performed on infected human teeth. This report investigated the immunofluorescent histologic outcomes of REPs in which repeated canal disinfection was required.

Methods: An 11-year-old girl presented with a fractured dens evaginatus (#29) with a sinus tract.

Long-term Success and Survival of Endodontic Microsurgery.

Introduction: Healed rates of endodontic microsurgery (EMS) may decrease over time, but research on the long-term outcomes is scarce. The aims of this retrospective cohort study were to evaluate the 5- to 9-year healed and survival rates of EMS, to identify associations between prognostic factors and healing status, and to compare the short-term (1- to 2-year) with long-term (5- to 9-year) outcomes.

Methods: One hundred fifty-one eligible patients (166 teeth) who underwent EMS in 2007-2010 were invited for a follow-up examination.

Matrix Metalloproteinase Inhibitor as an Antimicrobial Agent to Eradicate Enterococcus faecalis Biofilm.

Introduction: Successful endodontic treatment outcomes require new strategies for the complete eradication of microbial biofilms in the root canal system. Matrix metalloproteinases (MMPs) are essential enzymes in microbial cell growth and homeostasis, and they require transition metal ion cofactors to function. Targeting MMP activity also preserves dentin collagen integrity.

Isolation of alkaline-tolerant bacteria from primary infected root canals.

Introduction: Alkaline-tolerant bacteria in primary infected root canals could have enhanced survival capacity against antimicrobials commonly used in root canal treatment. The aims of this study were to isolate and characterize alkaline-tolerant bacteria before endodontic treatment (S1), after chemomechanical root canal preparation (S2), and after calcium hydroxide dressing (S3).

Methods: Bacteriologic samples were obtained from 43 primary infected root canals.

Prognostic factors relating to the outcome of endodontic microsurgery.

Introduction: The aim of this retrospective study was to evaluate the outcome of endodontic microsurgery and to examine prognostic factors related to healing.

Methods: The clinical records of all patients who had undergone endodontic microsurgery from 1997-2003 at the National Dental Centre of Singapore were examined. Teeth with a recall period of 1-2 years were selected.

N-acetylcysteine inhibits growth and eradicates biofilm of Enterococcus faecalis.

Introduction: The aims of this study were to evaluate the antibacterial and biofilm eradication efficacies of N-acetylcysteine (NAC) on Enterococcus faecalis.

Methods: The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of NAC on E. faecalis were determined.

The effect of EDTA with and without ultrasonics on removal of the smear layer.

This study evaluated in vitro effectiveness of 17% EDTA with and without ultrasonics on smear layer removal. One hundred and five extracted premolars randomly divided into seven groups were instrumented with different final irrigating protocols: group A (Sal3US), saline for 3 minutes with ultrasonics; groups B (Na3) and C (Na3US), 1% sodium hypochlorite for 3 minutes without and with ultrasonics, respectively; groups D (ED3) and E (ED3US), 17% EDTA for 3 minutes without and with ultrasonics, respectively; and groups F (ED1) and G (ED1US), 17% EDTA for 1 minute without and with ultrasonics, respectively. Specimens were examined under scanning electron microscope and scored for smear layer and debris removal.

Effect of EDTA with and without surfactants or ultrasonics on removal of smear layer.

This study compared the in vitro efficacy of Smear Clear (Sybron Endo, CA), a 17% ethylenediaminetetraacetic acid (EDTA) solution with surfactants, to 17% EDTA, with and without the use of ultrasonics, in removal of the smear layer. Seventy-five extracted teeth, randomly distributed into 5 test groups, were prepared by using ProFile rotary instruments (Dentsply Maillefer, Ballaigues, Switzerland) and subjected to different final irrigating regimes; group A, 1% sodium hypochlorite; group B, 17% EDTA; group C, 17% EDTA with ultrasonics; group D, Smear Clear; and group E, Smear Clear with ultrasonics. Samples were examined under the scanning electron microscope and scored for debris and smear layer removal.
