Bond Strength of Total-Etch Dentin Adhesive Systems on Peripheral and Central Dentinal Tissue: A Microtensile Bond Strength Test
Authors: Yeşilyurt C. , Bulucu B. 
Published: July 2019

Abstract

Objective
The purpose of this study was to evaluate the microtensile bond strength (μ TBS) of four total-etch adhesives [Excite (EB), Prime & Bond NT (PBNT), Single Bond (SB), and One Coat Bond (OCB)] by comparing them to five self-etching adhesives (Clearfil SE Bond (CSEB), Xeno III (X III), Prompt L-Pop (PLP), AQ Bond (AQB), and Tyrian/One Step plus (TOSP)] at different dentinal areas. In addition the interface between the adhesive resins and dentin was examined using scanning electron microscopy (SEM).

Methods and Materials
Superficial occlusal dentin of extracted human molars was exposed and finished with wet 800-grit silicon carbide paper. A block of composite resin was then bonded to the molar samples with the above adhesives according to the manufacturers’ instructions. After 24 hours in water at 37°C, the specimens were sectioned into 1 mm thick slices and divided into two regional subgroups according to their relationship to pulp tissue using visual criteria: pulp center and pulp periphery. The slices were then trimmed for the microtensile bond test and subjected to a tensile force and crosshead speed of 1 mm/min. Two-way analysis of variance was performed for statistical analyses. In addition the bond strengths for nine adhesive systems for each dentinal area were compared using the Post-Hoc test. The resin-dentin interfaces for each adhesive system were observed under a SEM.

Results
Mean μ TBS ranged from (25.2 MPa) for TOSP to (48.9 MPa) for PBNT. The bond strengths of total-etch adhesive systems were not significantly different, and were higher than self-etch adhesive systems, except for CSEB (p<0.05). No significant regional difference was observed for all of the nine adhesive systems (p>0.05). SEM observation showed there is not a standard hybridization for adhesive systems.

Conclusion
Different dentinal areas may not exhibit as great an influence on bond strengths using new adhesive systems.

AbstractAimsThe aim of this study was to determine the prevalence, severity, and pattern of dental caries in 6 to 7- year-old children in military primary schools in Jeddah city, Saudi Arabia.Methods and MaterialsA random sample of 300 children (6 to 7-year-olds) was drawn from six schools of military dependents. Clinical examinations were carried out under standardized conditions by two trained and calibrated examiners (MAM) and (YR). Caries were diagnosed using the British Association for the Study of Community Dentistry (BASCD) criteria.ResultsCaries were diagnosed in 288 (96%) of the children, and only 4% were clinically caries free. Mean decayed, missing, and filled teeth (dmft) for the 300 children was 8.06 (+ 4.04) per child and mean decayed, missing, and filled surfaces (dmfs) was 23.18 (+ 15.64). The teeth most affected by caries were mandibular primary second molars (83.35%), and the least affected were mandibular primary central incisors (1.15%).ConclusionsThe level of caries was higher than seen in children of equivalent age in other studies. The level of caries is expected to increase in permanent dentition. The above findings stress the need for an effective program of oral prevention in these children, such as a school dental health education program for children and their parents in order to improve their oral health status.CitationAl-Malik MI, Rehbini YA.

AbstractObjectiveThis study investigates the clinical performance of fixed space maintainers placed on seriously damaged abutment teeth.MethodsCrowns were placed on damaged abutment primary teeth. Fixed space maintainers were prepared by using rectangular wire between the window in the facial surface of the crowns and other abutment teeth and were subsequently bonded with a flowable resin composite. This procedure was introduced clinically, and the cases were observed over a period of twelve months.ResultsTwenty-seven fixed space maintainers (25 on lower jaw, two on upper jaw) were included in this study. No clinical failure was recorded in any of the cases in the observation time, and the rate of clinical performance was 100%.ConclusionThe study shows the effectiveness of fixed space maintainers combined with stainless steel crowns (“open-face fixed space maintainers”) which were placed on primary molar teeth used as abutments in cases with extensive caries and loss of occlusogingival dimension.CitationYilmaz Y, Kocogullari ME, Belduz N.

AbstractThis cross-sectional study aimed to evaluate the primary canine and the primary molar relationship in 205 (90 girls and 115 boys) three to six year-old Turkish children with the primary dentition in centric occlusion according to gender and age. In terms of the molar relationship, Class I was represented by 88.29% of all children who agreed to participate in the study, followed by Class II (7.31%), and Class III (4.4%). In terms of the canine relationship, Class I was represented by 87.8% of the sample, followed by Class II (7.8%), and Class III (4.4%). A statistically significant difference was found between age and both the canine and molar relationships (p<0.005), and a positive correlation was confirmed among them. However, the difference and correlation between the gender and the canine and molar relationships were not significant.CitationYilmaz Y, Gürbüz T, Şimşek S, Dalmiş A.

AbstractAimThe objective of this study was to radiographically assess and compare the quality of post-retained crowns fabricated at the Dental Health Centre of the Jordan University of Science & Technology (JUST).Methods and MaterialsStudy data were collected in 2002 from existing dental records for all patients receiving treatment with post-retained crowns between October, 1997 and June, 1999. The posts were assessed radiographically to evaluate various aspects of the quality of post-retained crowns. All 129 posts were fabricated in the dental school.ResultsThe most-frequently restored teeth were the maxillary incisors (38.8%). Sixty-two percent of the posts were tapered, while 38% were parallel-sided. The mean length of the posts was 0.95 mm (SD 0.41) with a range between 0.22-2.85 mm. Caries was diagnosed radiographically in 10.8% of cases with lesions located on root surfaces in 64.3% of them, while 35.7% of lesions were within the root canal. Three posts (2.3%) were deviated from the line of the root canal in the mesio-distal plane. No evidence of root filling was found in 2.3% of the cases. In the remainder of teeth 15.5% had gutta percha extended to the radiographic apex of the tooth, while 59.7% fell 0.5-1 mm short of the radiographic apex. Gutta-percha was extruded beyond the apex in 22.5% of the teeth. Space between the end of the post and the root filling was found in 22.2%. The percentage of canals with apparently completely healthy periapical tissue was 51.2%. In the rest of the cases 34.8% had areas of radiolucency at or near the root apices and 14% demonstrated widening of the periodontal space around the root apex. Root resection had been completed in 2.3% cases. Signs of external resorption were apparent in one case (0.78%).ConclusionThe standards of the treatment of the endodontically treated teeth made at the dental hospital were satisfactory but could be improved by a controlled academic supervisory environment and a strict scientific approach to fixed prosthodontics within the dental school.CitationAl-Hamad KQ, Al-Omari M, Al-Wahadni A, Darwazeh A.

A Review of Polymerization Shrinkage Stress: Current Techniques for Posterior Direct Resin Restorations
Authors: Giachetti Luca , Russo Daniele Scaminaci , Bambi Claudia , Grandini Romano 
Published: July 2019

Abstract
In general excellent results cannot be guaranteed when using resin-based composites for posterior restorations. This is due to polymerization shrinkage which can still be regarded as the primary negative characteristic of composite resins.
A review of available literature regarding the polymerization process, its flaws, and suggested strategies to avoid shrinkage stress was conducted.
Several factors responsible for the polymerization process may negatively affect the integrity of the tooth-restoration complex. There is no straightforward way of handlling adhesive restorative materials that can guarantee the reliability of a restoration. At present, the practitioner has to coexist with the problem of polymerization shrinkage and destructive shrinkage stress. However, evolving improvements associated with resin-based composite materials, dental adhesives, filling, and light curing techniques have improved the predictability of such restorations.
This critical review paper is meant to be a useful contribution to the recognition and understanding of problems related to polymerization shrinkage and to provide clinicians with the opportunity to improve the quality of composite resin restorations.

Primary Tuberculosis Clinically Presenting as Gingival Enlargement: A Case Report
Authors: Karthikeyan B.V. , Pradeep A.R. , Sharma C.G. Dileep 
Published: July 2019

Abstract
Tuberculosis is a chronic systemic granulomatous disease which rarely affects the oral cavity. Oral lesions can be either primary or secondary to systemic tuberculosis, the former being rare. This is a never-before reported case of primary tuberculosis presenting as a localized diffuse gingival enlargement in an 11-year-old Indian female patient. The diagnosis was reached through identification of positive histopathological features, Tuberculin test results, presence of anti-tubercular antibodies confirmed by a polymerase chain reaction. In view of the recent increase in the incidence of tuberculosis and the prevalence of the same, it is reasonable to include tuberculosis in the differential diagnosis of gingival enlargements. This is essential to avoid any serious complications for both the clinician and patient due to a delay in the diagnosis of such a rare but plausible oral condition.

Published: July 2019

Abstract

Aim
The aim of this study was to evaluate the microleakage of seven adhesive systems on two substrates (enamel and dentin).

Methods and Materials
Class V cavities were performed in buccal and lingual surfaces of 56 bovine incisors. The cervical margin was located in dentin and the incisal margin in enamel. The specimens were randomly divided into seven groups (n=16), according to the adhesive system employed: Single Bond; Excite; One Step Plus; Gluma One Bond; Magic Bond; One Up Bond F; and One Coat Bond. The cavities were incrementally filled with a hybrid composite Filtek Z250 and polymerized with a XL 3000 light curing unit. After polishing, the specimens were submitted to thermal cycling followed by dye immersion. Leakage was evaluated under magnification (40X) based on a standard ranking. Data were subjected to statistical analysis (Kruskal-Wallis).

Results
Enamel margins exhibited lower leakage than dentin margins (p<0.01). The majority of the specimens were leakage-free and materials performed similarly. Conversely, in dentin most of the specimens exhibited the highest leakage degree and significant differences among materials (p<0.05) were found, with Excite exhibiting the lowest leakage degree. It was concluded enamel provided better sealing and the adhesive system was a significant factor only in dentin.

Geometric and Mathematical Proportions and their Relations to Maxillary Anterior Teeth
Authors: Fayyad Mohammed Ali , Jamani Kifah Dafi , Aqrabawi Jamal 
Published: July 2019

AbstractAimOne of the critical aspects of esthetic dentistry is creating geometric or mathematical proportions to relate the successive widths of the anterior teeth. The golden proportion, the recurring esthetic dental (RED) proportion, and the golden percentage are theories introduced in this field. The aim of this study was to investigate the existence of the golden proportion, RED proportion, and the golden percentage between the widths of the maxillary anterior teeth in individuals with natural dentition.Methods and MaterialsStandardized frontal images of 376 dental student smiles were captured. The images were transferred to a personal computer, the widths of the maxillary anterior teeth were measured, and calculations were made according to each of the above mentioned theories. The data were statistically analyzed using paired student T-test (level of significance P<0.05).ResultsThe golden proportion was found to be accurate between the width of the right central and lateral incisors in 31.3% of men and 27.1% of women. The values of the RED proportion were not constant, and the farther the one moves distally from the midline the higher the values. Furthermore, the results revealed the golden percentage was rather constant in terms of relative tooth width. The width of the central incisor represents 23%, the lateral incisor 15%, and the canine 12% of the width of the six maxillary anterior teeth as viewed from the front.ConclusionsBoth the golden proportion and the RED proportion are unsuitable methods to relate the successive widths of the maxillary anterior teeth. However, the golden percentage theory seems to be applicable to relate the successive widths of the maxillary anterior teeth if percentages are adjusted taking into consideration the ethnicity of the population.CitationAli Fayyad M, Jamani KD, Aqrabawi J.

Authors: Al Wazzan Khalid A. , Al-Nazzawi Ahmad A. 
Published: July 2019

Abstract

Aim
The purpose of this in vitro study was to investigate the marginal accuracy and internal fit of complete cast crowns and three-unit fixed partial dentures (FPDs) cast with commercially pure titanium (CPTi) and Titanium-Aluminum-Vanadium alloy (Ti-6Al-4V).

Methods and Materials
CPTi and Ti-6Al-4V alloy were used to cast twelve single crowns and twelve three-unit FPDs. A traveling microscope was used to measure marginal gap and discrepancies in internal fit. Two and oneway analysis of variance (ANOVA) analyses were used to determine the effects of the marginal and internal fit discrepancies.

Results
The Ti-6Al-4V alloy demonstrated a significantly smaller marginal gap than CPTi (P<0.0001). The recorded marginal discrepancies for both metals were within a clinically accepted range (<100 ìm). The single crown fit discrepancy was significantly smaller than the three-unit FPD for both the CPTi and the Ti-6Al-4V alloy (P<0.0001). For the internal fit discrepancy, the occlusal surface showed the greatest gaps.

Conclusions
The Ti-6Al-4V alloy demonstrated a better fit than CPTi. Single crowns showed an improved fit when compared with the three-unit FPD. Mid-occlusal internal gap demonstrated greater values than the axial internal gap.

Clinical Implications
This in vitro study suggested marginal fit of complete crowns and three-unit FPDs cast by CPTi or Ti-6Al-4V alloy were within the range of what is clinically acceptable for longevity of restorations.

Published: July 2019

AbstractHistorically, wearing adornments on pierced body parts has been associated with many cultures as manifestations of religious or cultural identities. Currently, its use has a broad acceptance among young people. The most common sites for piercings are the tongue and lower lip in the oral cavity. Several complications may be associated with this practice with the most frequently observed being halitosis, periodontitis, tooth fracture, glossitis, and the formation of abscesses. This paper is a case report of a patient who had a complication from a piercing on the tongue located under the overlying mucosa. It also suggests a local habit was a possible initiator of this complication.CitationShinohara EH, Horikawa FK, Ruiz MM, Shinohara MT. Tongue Piercing: Case Report of a Local Complication.

Published: July 2019

Abstract
Hereditary gingival fibromatosis (HGF) is a rare condition characterized by varying degrees of gingival hyperplasia. Gingival fibromatosis usually occurs as an isolated disorder or can be associated with a variety of other syndromes.
A 33-year-old male patient who had a generalized severe gingival overgrowth covering two thirds of almost all maxillary and mandibular teeth is reported. A mucoperiosteal flap was performed using interdental and crevicular incisions to remove excess gingival tissues and an internal bevel incision to reflect flaps. The patient was treated 15 years ago in the same clinical facility using the same treatment strategy. There was no recurrence one year following the most recent surgery.

Effect of Centripetal and Incremental Methods in Class II Composite Resin Restorations on Gingival Microleakage
Authors: Moosavi Horieh , Ghavamnasiri Marjaneh , Tahvildarnejad Najmeh 
Published: July 2019

Abstract

Aim
The aim of this study was to evaluate the microleakage at gingival margins below the cementoenamel junction (CEJ) of Class II composite restorations using various placement techniques.

Methods and Materials
Sound human maxillary premolars were selected. Eighty slot-style cavities on the mesial or distal surfaces were prepared with the cervical margins located apical to the CEJ. The specimens were divided into two groups based on the restorative technique utilized (centripetal or incremental). Each group was then categorized into two subgroups according to the type of matrix used resulting in a total of four experimental groups as follows: IP=Incremental and Palodent matrix, IT = Incremental and Transparent matrix, CP = Centripetal and Palodent matrix, and CT = Centripetal and Transparent matrix.
Following restoration with a total etch adhesive (Single Bond) and a resin composite (Z100), the teeth were thermocycled. Then specimens were immersed in 0.5% basic fuchsin dye for 24 hours at a temperature of 37°C. Sectioned restorations were examined under a stereomicroscope (40X magnification), and the extent of the microleakage was scored and recorded. Data were analyzed using the Kruskal-Wallis non-parametric statistical test (P=0.05).

Results
In the four groups of the study no significant differences in the mean rank of microleakage were observed (p>0.05).

Conclusion
When the gingival margin was located on cementum, the kind of matrix and filling technique did not reduce the microleakage.
