Why do dentists refrain from intervention in cases of persistent asymptomatic apical periodontitis in root canal filled teeth? An interview study among general dental practitioners.

Aim: To explore the context in which general dental practitioners (GDPs) decide to refrain from further treatment, that is, ortho- or retrograde retreatment or extraction of a root canal filled tooth with persistent asymptomatic apical periodontitis (PAAP).

Methodology: Fifteen GDPs were strategically selected for in-depth interviews. The informants were encouraged to describe in their own words and in as much detail as possible, the three most recent patient cases of PAAP of a root canal filled tooth, in which they decided to refrain from further treatment.

Further Interventions after Root Canal Treatment Are Most Common in Molars and Teeth Restored with Direct Restorations: A 10-11-Year Follow-Up of the Adult Swedish Population.

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 10-11 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, and unspecified) registered within 6 months of root filling.

General dental practitioners' fees for root canal treatment, coronal restoration and follow-on treatment in the adult population in Sweden: A 10-year follow-up of data from the Swedish Dental Register.

Objectives: To analyze the accumulated fees connected with root filling, permanent coronal restoration and follow-on treatment charged by Swedish dentists over a 10-11-year follow-up period. Furthermore, analyzing these fees with reference to the type of restoration, tooth group, and the root-filled teeth which survived compared to those requiring extraction.

Material And Methods: In 2009, the data register of the Swedish Social Insurance Agency recorded a total of 215,611 teeth as root-filled.

Periradicular surgery: a longitudinal registry study of ten-year outcomes and factors predictive of post-surgical extraction.

Aim: This historical prospective cohort study of the adult population of Sweden is based on data from a national registry: the primary aim was to evaluate the long-term survival of teeth after periradicular surgery. A secondary aim was to identify factors predictive of extraction within 10 years of registration of periradicular surgery.

Methodology: The cohort consisted of all individuals who had undergone periradicular surgery to treat apical periodontitis, as reported to the Swedish Social Insurance Agency (SSIA) during 2009.

Tooth survival after endodontic treatment.

There are several measures that are, or could be, in use in relation to estimating the outcome of endodontic treatments. It is important to reflect on when and why a certain outcome measure is used; when caring for an individual patient it is obvious that the goal always should be a tooth in a healthy state, that is striving to remove any infection and aim for the tooth to have healthy periapical tissues. For patients in general and for society, it is also interesting to know if endodontic treatments will lead to retention of teeth in a functioning state.

The role of extended lymph node dissection in patients undergoing radical cystectomy.

Radical cystectomy (RC) with a pelvic lymph node dissection (LND) is the gold standard for the treatment of muscle invasive bladder cancer (MIBC) as well as for some high-risk non-muscle invasive bladder cancers. The therapeutic advantage of LND, in terms of cancer-specific survival (CSS), still divides opinion and, certainly, the question of the extent of LND at the time of cystectomy is still debated. In this article, we have reviewed the evidence supporting the practice of extending LND in order to help clinicians determine what is appropriate in their practice.

Pilot study of an integrated model of sleep support for children: a before and after evaluation.

Objective: Despite the success of behavioural sleep support interventions in the third sector, sleep support is not universally available for families in the UK. The aim of the study was to provide evidence of efficacy and to propose a delivery model for integrated sleep support for families of vulnerable children.

Design And Setting: A sleep support intervention was carried out in Sheffield Local Authority evaluated using a preintervention and postintervention study design by Sheffield Children's National Health Service (NHS) Trust.

Further Treatments of Root-filled Teeth in the Swedish Adult Population: A Comparison of Teeth Restored with Direct and Indirect Coronal Restorations.

Introduction: The aim of this study was to evaluate the frequencies of nonsurgical retreatment, root-end surgery, extraction, and further restoration of root-filled teeth in Sweden in 2009 during a follow-up period of 5 years and to compare the outcomes in teeth restored with direct or indirect restorations.

Methods: Data from the Swedish Social Insurance Agency were analyzed, and the frequencies of nonsurgical retreatment, root-end surgery, extractions, and further restoration were calculated for all teeth registered as root filled during 2009. Chi-square tests were applied to detect any significant differences in the frequency of further treatment in teeth registered as restored with either a direct or an indirect restoration within 6 months of root filling.

Periapical Status of Root-filled Teeth Restored with Composite, Amalgam, or Full Crown Restorations: A Cross-sectional Study of a Swedish Adult Population.

Introduction: The aim was to compare the periapical status of root-filled teeth restored with resin composite, laboratory-fabricated crowns, or amalgam in a Swedish adult population.

Methods: The subjects consisted of 440 individuals from a randomly selected sample of 1000 adult residents of a Swedish county. The type, material, and quality of the restorations were recorded for all root-filled teeth by using clinical examination and intraoral clinical photographs.

Survival of Root-filled Teeth in the Swedish Adult Population.

Introduction: The aim was to assess survival in the Swedish population of teeth treated by nonsurgical root canal treatment during 2009.

Methods: Data from the Swedish Social Insurance Agency were analyzed by Kaplan-Meier analysis to assess cumulative tooth survival during a period of 5-6 years of all teeth that were root-filled during 2009.

Results: In 2009, 248,299 teeth were reported as root-filled.

Periapical status of non-root-filled teeth with resin composite, amalgam, or full crown restorations: a cross-sectional study of a Swedish adult population.

Introduction: Experimental studies show that dental pulp cells respond unfavorably to contact with resin composite restorative material. Hypothetically, in a random population, the frequency of apical periodontitis should be higher for teeth restored with resin composite than with amalgam. Therefore, the aim was to compare the periapical status of non-root-filled teeth restored with resin composite, amalgam, or laboratory-fabricated crowns in an adult Swedish population.
