Four-Handed Dentistry Revisited
Authors: Finkbeiner Betty Ladley 
Published: July 2019

Abstract
A great deal of new technology has been integrated into the modern dental office during the last several decades. However, no product can increase productivity and reduce stress and strain on the dental team as much as using the singular concept of four-handed dentistry. The research of the 1950s is undaunted in its impact on productivity. Combined with the practice of ergonomics in the workplace, this concept must be revisited by the dental profession. The young dentists of the 21st Century have had minimal exposure to true four-handed dentistry. This article, the first in a series, re-introduces the basic principles of a research-oriented concept.

Published: July 2019

AbstractAimThe purpose of this study was to compare the fracture resistance of endodontically treated teeth restored with different post and core systems in combination with complete metal crowns in teeth with no coronal structure.Methods and MaterialsFifty extracted mandibular premolars were divided into five groups. The coronal portion of each tooth was removed at the cementoenamel junction (CEJ) in all groups except Group 1. In this group the teeth were sectioned 1 mm above the CEJ to create a ferrule. After root canal preparations, cast posts were placed in the first four groups. Prefabricated glass fiber posts and composite cores were placed in the fifth group. An opaque porcelain layer was applied to the metal post surfaces in the third group and an alloy primer was applied to the posts in the fourth group before using Panavia F2 resin cement. No bonding agent or surface treatments were used for the first and second groups. A Ni-Cr full cast crown for each sample was prepared and cemented. A compressive load was applied at an angle of 45 degrees to the crown with a universal testing machine. After 500,000 mechanical cycles at 1.5Hz, the maximum load at fracture (N) was recorded.ResultsSignificantly higher fracture resistance values (216.87 N) and survival rates (75%) were demonstrated for non-ferrule teeth restored with opaque layered posts than for other non-ferrule groups. The prefabricated post group showed the most favorable fracture pattern in all test groups (P=0.04).ConclusionEither a ferrule preparation or bonding with the use of an opaque porcelain layer can increase the fracture resistance of teeth with little remaining tooth structure that are restored with cast crowns following endodontic therapy.Clinical SignificanceBonding cast posts to the tooth structure has a significant effect on compensating for the lack of a ferrule on endodontically treated teeth.CitationDorriz H, Alikhasi M, Mirfazaelian A, Hooshmand T.

The Influence of Adhesive Luting Systems on Bond Strength and Failure Mode of an Indirect Micro Ceramic Resin-based Composite Veneer
Authors: Ghavamnasiri Marjaneh , Sarabi Nasrin , Forooghbakhsh Azadeh 
Published: July 2019

Abstract

Aim
This study evaluated the bond strength and failure mode of enamel/resin-based composite veneers bonded with three different dual cured resin adhesive systems.

Methods and Materials
Standard preparations for laminate veneer restorations were made on 30 human central incisors using depth cutting burs (0.5 mm depth at the incisal area and 0.3 mm at the gingival area). Thirty indirect laminates were prepared using a highly filled polymeric material (GC Gradia) according to the manufacturer's instructions. After sandblasting the fitting surfaces, the specimens were randomly divided into three groups (ten per group) based on the type of resin cement luting systems; Excite/Variolink II, Single Bond/ Rely X Veneer Cement, and Clearfil New Bond/Panavia F. The specimens were stored in water at 37°C for 48 hours. Fracture testing was performed using a universal testing machine where the load was applied from the incisal direction at 135° to the long axis of the tooth (0.5 mm/min). The one-way analysis of variance (ANOVA) and Chi-Square tests were used for statistical analysis at a significance level of p>0.05.

Results
The ANOVA showed no significant difference was found among the groups (P>0.05). Indirect veneers showed mean enamel bond strength of 114.4 ± 48N, 159.7 ± 83.4 N, and 126.1 ± 51.7 N with Variolink II, Rely X veneer cement, and Panavia F, respectively. The Chi-Square tests showed no significant difference regarding the failure mode frequencies in different types of failure in the three groups (p>0.05). The failure mode analysis showed mainly adhesive failure in the resin cement/laminate interface in all groups.

Conclusion
There was no significant difference in bond strength of veneers with the three different resin cements tested. In addition, there was no significant difference in the frequency of the failure mode in each type of failure among the three test groups. The failure analysis revealed mainly an adhesive failure at the resin cement/veneer interface.

Clinical Significance
The results of this study suggest the use of Excite/Variolink, Single Bond/RelyX, or Clearfil New Bond/Panavia F are all appropriate choices for luting of indirect micro ceramic resin-based composite veneers in terms of bond strength and failure mode.

Outcome of Root Canal Treatment Using Soft-Core™ and Cold Lateral Compaction Filling Techniques: A Randomized Clinical Trial
Authors: Özer Senem Yigit , Aktener B. Oguz 
Published: July 2019

AbstractAimThe purpose of this clinical and radiographic investigation was to evaluate the treatment outcomes of endodontically treated teeth obturated with Soft-Core™ versus cold lateral compaction.Methods and MaterialsA total of 98 teeth were endodontically prepared using the Quantec LX rotary system with a crown-down pressureless technique and obturated with either Soft-Core™ or cold lateral compaction. The outcome of treatments were evaluated clinically and radiographically by two blinded evaluators after three years. Statistical analysis was performed using an unpaired t-test and the Mann Whitney test at the level of significance set at 95%.ResultsRegardless of the periapical status of the teeth, no statistically significant difference was found between the two obturation techniques (p>0.05). The Kappa value for the interobserver agreement was 0.73.ConclusionWithin the limits of the study, it is concluded the Soft-Core obturation technique did not result in a significantly different treatment outcome when compared with cold lateral compaction after three years. Further investigations should be carried out on the Soft-Core technique.Clinical SignificanceUsing the Soft-Core system reduced working time, and the difference was found to be statistically different (p=0.00056) from the working time required for cold lateral compaction. This reduction in canal filling time holds the potential for cost savings for clinicians while maintaining the quality of the clinical outcome.CitationÖzer SY, Aktener BO.

Exploring the Relationships between Sense of Hopelessness, Worry, Self-rated Oral Health Status, and Behavior in a Romanian Adult Population
Authors: Dumitrescu Alexandrina L. , Kawamura Makoto 
Published: July 2019

AbstractAimThe purpose of this study was to examine the impact of psychological states, self-rated oral health, and oral health behavior on hopelessness.Methods and MaterialsA cross-sectional study design was used. Data were collected between September and November 2006. The sample consisted of 233 Romanian adults (mean age 47.3 years; 65.6% women; 65.8% married). The questionnaire included information about demographic, psychological, self-reported oral health, and oral health related behavior items.Results‘Hopeless’ participants were more likely to self-evaluate their dental health as poor/very poor (P<0.001), to be less satisfied by the appearance of their teeth (P<0.05), to report more non-treated caries (P<0.01), to brush their teeth less than twice per day (P<0.01), and never use mouthrinse (P<0.05). Logistic regression analysis showed ‘hopeless’ participants were apt to have a lower educational level, brush less frequently, have higher financial problems as the reason for not visiting the dentist, and report higher anxiety (odds ratio = 5.4, 4.2, 2.6, and 12.6, respectively). Forty-seven (73.4%) of 64 ‘hopeless’ participants and 90 (80.4%) of 112 ‘non-hopeless’ participants were correctly predicted by the above four variables.ConclusionThe results of this study found impaired oral health and financial problems may pose an increased risk for hopelessness.Clinical SignificancePoor oral health can be regarded as a risk marker for the level of hopelessness.CitationDumitrescu AL, Kawamura M.

Authors: de Oliveira Marilia Gerhardt , Weber João Batista Blessmann , Costa Aline Tempel , Konrath Francine , Dedavid Berenice 
Published: July 2019

Abstract

Aim
The purpose of this investigation was to evaluate the marginal adaptation of five root-end filling materials.

Methods and Materials
Fifty human single-rooted teeth were resected 3 mm from the apex. Root-end cavities were then prepared using an ultrasonic tip and filled with one of the following materials: silver amalgam without zinc, white MTA-Angelus, white Portland cement (PC), Vitremer™, and GC Fuji Ortho™ LC. The apical portion of the roots was then sectioned to obtain two 1 mm thick transversal sections. Epoxy resin replicas of these apical sections were fabricated for an analysis of marginal adaptation. Scanning electron microscopy (SEM) was used to determine gaps in the adaptation of the root-end filling materials at the interface between them and the dentin. The Kruskal-Wallis test and a multiple comparison test were used for statistical data analysis. The Spearman correlation coefficient was used to determine the correlation between the results found for teeth and replicas.

Results
Materials containing calcium oxide (MTA and PC) showed similar results. Resin modified glass ionomer cements (GICs) presented similar variations in marginal adaptation, but Vitremer™ showed significantly greater marginal adaptation when compared to GC Fuji Ortho™ LC.

Conclusion
A positive and significant correlation was observed between marginal adaptation values found in the teeth and their replicas.

Clinical Significance
The use of ionomers as root-end filling materials may improve clinical outcomes in periradicular surgery.

Anticariogenicity of Casein Phosphopeptide-amorphous Calcium Phosphate: A Review of the Literature
Authors: Llena Carmen , Forner Leopoldo , Baca Pilar 
Published: July 2019

Abstract

Aim
This review of the literature examines the role of the natural components of saliva in maintaining tooth mineralization and the role of different casein phosphopeptide amorphous calcium phosphate-based (CPP-ACP) compounds in controlling demineralization/ remineralization and their clinical applications.

Background
A group of peptides, known as CPP, have been shown to stabilize calcium and phosphate preserving them in an amorphous or soluble form known as amorphous calcium phosphate (ACP). Calcium and phosphate are essential components of enamel and dentine and form highly insoluble complexes, but in the presence of CPP they remain soluble and biologically available. This CPP-ACP complex applied to teeth by means of chewing-gum, toothpaste, lozenges, mouth rinses, or sprays is able to adhere to the dental biofilm and enamel hydroxyapatite providing bioavailable calcium and phosphate ions.

Review Results
Significantly high levels of calcium and phosphate have been found in both biofilm and subsurface incipient caries lesions and in lower level demineralization of enamel or dentine surfaces previously treated with CPP-ACP based compounds. When placed on the surface of a tooth with early carious lesions, pastes with CPP-ACP complexes can prevent tooth demineralization and improve enamel remineralization and enhance fluoride activity.

Conclusion
Remineralization of white spot lesions has been achieved clinically by applying pastes based on these compounds, and a similar effect to self-applied fluorides has been observed in reducing the appearance of new caries lesions in patients with xerostomia.

Clinical Significance
Use of CPP-ACP based compounds offers a potential for use in the prevention of dental caries.

Effect of Posts on the Fracture Resistance of Load-cycled Endodontically-treated Premolars Restored with Direct Composite Resin
Authors: Majidinia Sara , Ghavamnasiri Marjaneh , Hajizadeh Hila , Namazikhah Mohammad Sadegh , Moghaddas Mohammad Javad 
Published: July 2019

AbstractAimThe aim of this study was to investigate the fracture resistance and failure mode of premolars restored with composite resin using various prefabricated posts.Methods and MaterialsSixty sound maxillary premolars were divided into four equal sized groups. All but the control group received endodontic treatment followed by placement of mesiodistocclusal (MOD) composite restorations (Tetric Ceram) as follows: Group T = no post, Group DT = fiber reinforced composite (FRC) post (DT Light), Group FL = prefabricated metal post (Filpost). The control group (C) had no cavities prepared. After thermal and load cycling, static load was applied at a 30° angle until fracture. Failure modes were categorized as restorable and non-restorable. Data were analyzed using the analysis of variance (ANOVA) and Duncan tests (α = 0.05).ResultsThe mean values of fracture loads (N) for all groups were: C (880±258); T (691±239); DT (865±269); and FL (388±167). Statistically significant differences (P<0.05) were observed for all groups except between groups C and DT. The Chi Square test showed failure modes in groups C and DT were mostly restorable. The most non-restorable fractures were observed in group FT.ConclusionIntact teeth and the teeth restored with composite and quartz fiber posts had a similar fracture resistance and the failure modes were mostly restorable. The lowest fracture resistance and the most nonrestorable failures were observed in conjunction with metal posts.Clinical SignificanceThe results of thisin vitrostudy suggest the use of a quartz fiber post used in conjunction with an MOD composite resin restoration improves fracture resistance in an endodontically treated premolar.CitationHajizadeh H, Namazikhah MS, Moghaddas MJ, Ghavamnasiri M, Majidinia S.

The Effect of Different Adhesive Types and Curing Methods on Microleakage and the Marginal Adaptation of Composite Veneers
Authors: Moosavi Horieh , Maleknejad Fathemeh , Sarabi Nasrin , Shahriari Resa , Shayankhah Taybeh 
Published: July 2019

Abstract

Aim
The aim of this in vitro study was to evaluate the influence of application techniques (with pre-curing vs without pre-curing) for dentin adhesive on microleakage and marginal adaptation of indirect composite veneer restorations.

Methods and Materials
A total-etch bonding system, Excite/Variolink II (EXV), and a self-etching primer system, Panavia F2.0 (PF2), were used in the study. Forty-eight human central incisors were prepared for composite veneer restorations. The teeth were divided into two groups (n=24). For each resin cement, one half of each experimental group included an adhesive pre-cure (PC) with a halogen light source while the other half received no pre-cure (NPC) prior to resin cement insertion. Thus, four experimental groups were created: A (PC+EXV), B (NPC+EXV), C (PC+PF2), and D (NPC+PF2). Veneers made of Tetric Ceram resin composite were cemented using dual-cured resin luting agents. After storage in distilled water at 37°C for 24 hours, the teeth were prepared for marginal leakage. Two samples of each group were selected at random for scanning electron microscopic (SEM) observation and evaluation of marginal adaptation at 1050x magnification. Data were analyzed using the Kruskal-Wallis and Mann-Whitney tests (Ð <0.05).

Results
The highest and lowest microleakage values were observed in dentinal margins of groups B and A, respectively. Dentin margins opposite to enamel margins had a significant difference in microleakage values of PC and NPC groups (P<0.05). The influence of the adhesive pre-cure was more pronounced than the type of resin cement used. No adhesive layer was visualized for the adhesives used without employing the pre-curing step.

Conclusion
The effect of pre-cured adhesives was not material specific. The pre-cured adhesives showed the best resistance to dye penetration although the film thickness of these luting agents was only slightly increased.

Clinical Significance
Different curing methods (with pre-curing/without pre-curing) regardless of total-etch or self-etch adhesive systems influenced microleakage and the marginal adaptation, especially dentin margins of indirect composite veneers.

Fiber-reinforced Onlay Composite Resin Restoration: A Case Report
Authors: Garoushi Sufyan , Vallittu Pekka K. , Shinya Akikazu , Shinya Akiyoshi 
Published: July 2019

Abstract

Aim
The purpose of this case report is to describe the clinical procedure for fabricating fiber-reinforced composite (FRC) onlay composite resin restorations using a FRC as the substructure.

Background
A variety of therapeutic modalities are available to restore teeth with moderate coronal defects in the posterior region of the mouth. For patients who refuse complete crown restorations or when minimal tooth reduction is preferred, a FRC restoration can be a good alternative to conventional restorative techniques.

Case Report
A 42-year-old female patient presented with an endodontically treated mandibular right first molar with extensive destruction of the coronal tooth structure. To conserve the remaining tooth structure a FRC resin core substructure was fabricated and veneered with Ceramage dentin and enamel hybrid composite to create the final restoration.

Summary
FRC restorations using adhesive technology appears to be a promising restorative option. However, further clinical investigation will be required to provide additional information on this technique. Based on the clinical and radiographic findings in the present case, the fabrication of a conventional crown was avoided in order to conserve the remaining tooth structure.

Clinical Significance
The restoration of badly damaged teeth is a challenge for clinicians when cast crown restorations are not an option for the patient. The use of FRC restorations along with adhesive technology may be a rational restorative alternative in the near future.

Authors: Younis Luay , Taher Asraa , Abu-Hassan Mohamed Ibrahim , Tin Ong 
Published: July 2019

Abstract

Aim
The purpose of this study was to compare bone healing and coronal bone remodeling following both immediate and delayed placement of titanium dental implants in extraction sockets.

Methods and Materials
The study included 49 patients (28 women, 21 men) in need of implant treatment in the anterior teeth region of either the maxilla or mandible. Twenty-three subjects received 37 immediate (Im) implants and 26 subjects received 37 delayed (De) implants. The implants were placed immediately in the alveoli following the extraction in the Im group and the implants in the De group were placed approximately six months following the extractions. The width and depth of the marginal bone defects mesial and distal to the implants were evaluated radiographically using computer software designed to measure distances in digitized radiographs.
The mean reduction of bone defect over time was 48% (from 3.4 to 1.3 mm) in the Im group which was statistically significant (P <0.05) when tested using a sample t-test, while the mean reduction was 17% (from 2.1 to 1.9 mm) in the De group.

Conclusion
The potential exists for bone healing and remodeling in fresh extraction socket defects associated with immediately placed implants.

Clinical Significance
Im implantation offers the advantages of reduced operating time and the preservation of alveolar bone volume.
