#1
Falk Schwendicke, Michael Stolpe
OBJECTIVES: Dentists can choose between metal and fiber post systems to provide post-retained restorations. The risk of tooth loss and other complications differs between different post systems, as do the initial treatment costs. We aimed to assess the cost-effectiveness of (1) cast metal (MC), (2) preformed metal (MP), (3) glass fiber (GF), and (4) carbon fiber (CF) post-retained restorations. METHODS: A mixed public-private payer's perspective within German healthcare was taken...

INTRODUCTION: The aim of this systematic review was to answer the following clinical question: Which is the best treatment option for a pulpally involved tooth? METHODS: An electronic search was conducted in the Cochrane, PubMed (MEDLINE), and ScienceDirect databases between December 2015 and February 2016. A manual search was also performed. The inclusion criteria were randomized clinical trials, prospective or retrospective cohort studies, and cross-sectional studies performed on humans with at least 1 year of follow-up and published within the last 10 years...

INTRODUCTION: Teeth with a palatal radicular groove are challenging to diagnose, treat, and save. We classified this condition using cone-beam computed tomographic (CBCT) cross-sectional configurations combined with radiographic and morphologic observations during an intentional replantation procedure to identify and analyze the characteristics of palatal radicular grooves comprehensively as a reference for diagnosis, treatment planning, and prognosis evaluation of this condition. METHODS: Eight cases with palatal radicular grooves present in permanent maxillary incisors were investigated by radiography and CBCT imaging before intentional replantation...

Bacillus subtilis is nonpathogenic in humans and produces a number of useful substances and, therefore, this bacterium is used in probiotic therapy. There have been trials of B. subtilis for patients with periodontitis, but not for patients with caries. Similarly, mineral trioxide aggregate (MTA) cement has been widely used for endodontic treatment, but there are few reports of its use for caries. Therefore, examinations were performed regarding the benefits of addition of B. subtilis to MTA cement for treatment of dental caries...

Background and objectives: From the beginnings of modern orthodontics, questions have been raised about the extraction of healthy permanent teeth in order to correct malocclusions. A hundred years ago, orthodontic tooth extraction was debated with almost religious intensity by experts on either side of the issue. Sheldon Friel and his mentor Edward H. Angle both had much to say about this controversy. Today, after significant progress in orthodontic practice, similar arguments are being voiced between nonextraction expansionists and those who see the need for tooth extractions in some orthodontic patients...

Objective: Various factors have been examined in the literature in an attempt to reduce the incidence and severity of root resorption. The purpose of the present investigation is to test the null hypothesis that there is no difference in relation to force level using gradually increasing (ascending) and decreasing (descending) orthodontic force generated by magnets on the severity of Orthodontically Induced Inflammatory Iatrogenic Root Resorption (OIIRR) and amount of tooth movement. Methods: Twenty maxillary first premolars from 10 patients were subjected to ascending (25-225 g, magnets in attraction) and descending (225 to 25 g, magnets in repulsion) buccal forces using a split mouth design over an 8-week period...

Introduction: The aim of this study was to investigate the variation in the amount of the orthodontically induced cervical root resorption and the association with several factors, such as the amount of tooth displacement, location of tooth in the maxilla or mandible, and presence of an interference that may influence the amount of root resorption. Subjects and methods: This study included 30 subjects (20 females, 10 males) with an age range of 11.3 to 43.0 years...

The purpose of this study was to evaluate the effect of 0.05% sodium fluoride and 0.12% chlorhexidine mouthwashes on the micro-hardness of tooth enamel and cementum that was exposed to therapeutic doses of gamma radiation. Sixty extracted human teeth were divided into two groups, one was irradiated, the other was not irradiated. The two groups were further subdivided into three subgroups, which were each treated either with 0.05% sodium fluoride or with 0.12% chlorhexidine; the third subgroup served as a control...

Objectives The aim of this study was to evaluate the patients' willingness to pay (WTP) values and preference for the treatment of a tooth with very poor prognosis, among two options: root canal therapy and crown positioning or tooth extraction, implant insertion and crown positioning.Methods A total of 103 patients were recruited from a private dental clinic and interviewed. A questionnaire measured individuals' preferences among the two alternative treatments for a tooth with poor prognosis and the maximum amount of money they would be willing to pay for their choice with a starting bid of [euro]2,000 in [euro]100 increment/decrement...

Regular SPT (supportive periodontal treatment) retains teeth longer than irregular SPT but this regimen is not necessarily cheaper; extraction and replacement of teeth was usually the most expensive.

OBJECTIVES: Implant placement immediately after tooth extraction is often accompanied by resorption of surrounding tissues. A clinical technique was developed where the buccal portion of the root is retained to preserve the periodontal ligament and bundle bone. This technique is based on animal studies showing the potential to preserve the facial tissues utilizing this approach. The purpose of this study was to gain more insight regarding the safety of the technique with regard to biological and implant-related long-term complications and to observe the clinical appearance of the peri-implant tissues...

AIM: To evaluate the effect of three nickel-titanium (Ni-Ti) rotary systems with varying tapers on stress distribution and to analyse potential fracture patterns as well as the volume of fracture-susceptible regions in two-rooted maxillary premolars. METHODOLOGY: The root canals of three single-rooted premolars were prepared with either HeroShaper (Micro-Mega, Besançon, France) to (size 30, .04 taper), Revo-S (Micro-Mega) to AS30 (size 30, .06 taper) or ProTaper Universal (Dentsply Maillefer, Ballaigeus, Switzerland) to F3 (size 30, ...

PURPOSE: The aim of this study was to evaluate the effects of LED and low-intensity laser on the healing of rabbit dental alveoli. METHODS: A total of 18 rabbits were divided into three groups of six; all rabbits underwent surgical extraction of the first lower right premolar. Following surgery, group 1 received LED irradiation, group 2 received laser irradiation, and group 3 were untreated controls. The initial applications of LED and laser began 48 h after tooth extraction and were given perpendicularly to the dental alveoli...

The equine first premolar ("wolf tooth," Triadan number 05) is frequently extracted, and although extracted teeth have been observed to vary greatly in size, published data describing tooth dimensions are limited. Total length, root length, crown height, and crown width were measured in 65 extracted wolf teeth. Dimensions, expressed as median (range) mm, were total length: 21 (12-34), root length: 13.2 (0-19.6), crown height: 7 (2-20), and crown width: 7 (2.6-16). Root length exceeded crown height in 61 of the 65 teeth...

Malocclusion in dogs is commonly diagnosed in puppies when the primary dentition is present. Interceptive orthodontic treatment may be elected to temporarily resolve painful contact points with the primary dentition. However, the adult dentition must be monitored closely and treated to achieve a lifelong, pain-free occlusion. This case report illustrates interceptive orthodontic treatment of deciduous and permanent dentition to treat a class 2 malocclusion in a dog. Extraction of the permanent maxillary canine tooth was elected to resolve abnormal contact from the mandibular canine in a single anesthetic episode...
