Authors: Ustun Yakup , Erdogan Ozgur , Kurkcu Mehmet , Akova Tolga , Damlar Ibrahim 
Published: September 2019

ABSTRACTObjectives: The aim of this pilot study was to evaluate the effects of low intensity pulsed ultrasound (LIPU) on dental implant osseointegration in a rabbit model using mechanical-histomorphometric methods and resonance-frequency analysis (RFA).Methods: Twelve skeletally mature, male New Zealand rabbits (3.4 kg±0.5) were included in the study. A total number of 24 implants were placed bilaterally into the tibiae of the subjects. The right tibia of each rabbit received LIPU application (20 min/day) while the left side received sham treatment. The study was carried on for six weeks and the rabbits were sacrificed in 7 days intervals (two rabbits for each week). The rabbits were categorized in the early or late osseointegration period according to their sacrification date. Comparisons between the groups were made using statistical analysis of histomorphometric analysis, resonance frequency analysis and mechanical tests.Results: The histomorphometry parameters showed that the bone area and the bone volume values have significantly increased in the early osseointegration period and the bone-implant contact values have significantly increased in the late osseointegration period in the LIPU treated subjects when compared to the control group. RFA scores had mild increase in the LIPU group. However the difference was not statistically significant. Mechanical test results suggest an increased mechanical stability in the LIPU group as well.Conclusions: Results of this pilot study indicate that low intensity pulsed ultrasound may have positive effects on osseointegration and stability of dental implants.

Authors: Alkan Alper , Bulut Emel , Arici Selim , Sato Shuichi 
Published: September 2019

ABSTRACTObjectives: The purpose of this study was to investigate the short-term effects of occlusal splint therapy and tricyclic antidepressants on the bite force and occlusal contact area of patients presenting with nocturnal bruxism.Methods: A maxillary full-coverage hard acrylic splint was applied to the five patients (Group S). Five patients took a tricyclic antidepressant (Amitriptiline HCl, 10 mg/day) for 3 months (Group A) and a control group (Group C) comprising of 10 dental school students with normal occlusion was also formed. Using a Dental Prescale (Fuji Photo Film Corporation, Tokyo, Japan) and an Occluzer computer (FPD703, Fuji Photo Film Corporation, Tokyo, Japan) the bite force and occlusal contact area were measured. The evaluations were made just before the treatment and at 1 month and 3 months of treatment.Results: The bite force and occlusal contact area before treatment in study Groups A and S were found to be higher than those in the Group C. Furthermore, the bite force and occlusal contact area increased during treatment in Group A whilst they decreased in Group S. Bite force and occlusal contact area in Group S were lower at both 1 month and 3 months of treatment than in Group C.Conclusions: It could be tentatively suggested that occlusal splint therapy may be more effective than tricyclic antidepressant in the treatment of bruxism. Further investigations of this measurement method involving larger study populations and a longer follow-up period are needed. (Eur J Dent 2008;2:276-282)

Authors: Yasar Fusun , Akgunlu Faruk 
Published: September 2019

ABSTRACTObjectives: The aim was to assess whether Fractal Dimension and Lacunarity analysis can discriminate patients having different mandibular cortical shape.Methods: Panoramic radiographs of 52 patients were evaluated for mandibular cortical index. Weighted Kappa between the observations were varying between 0.718-0.805. These radiographs were scanned and converted to binary images. Fractal Dimension and Lacunarity were calculated from the regions where best represents the cortical morphology.Results: It was found that there were statistically significant difference between the Fractal Dimension and Lacunarity of radiographs which were classified as having Cl 1 and Cl 2 (Fractal Dimension P:0.000; Lacunarity P:0.003); and Cl 1 and Cl 3 cortical morphology (Fractal Dimension P:0.008; Lacunarity P:0.001); but there was no statistically significant difference between Fractal Dimension and Lacunarity of radiographs which were classified as having Cl 2 and Cl 3 cortical morphology (Fractal Dimension P:1.000; Lacunarity P:0.758).Conclusions: FD and L can differentiate Cl 1 mandibular cortical shape from both Cl 2 and Cl 3 mandibular cortical shape but cannot differentiate Cl 2 from Cl 3 mandibular cortical shape on panoramic radiographs.

Published: September 2019

ABSTRACTObjectives: The purpose of this study was to evaluate the cytotoxic effect of six dental adhesives (Admira Bond, Clearfil Liner Bond 2V, ED Primer II, Fuji Bond LC, Gluma Comfort Bond, and NanoBond) applied to cell cultures.Methods: The experiments were performed on two cell lines, rat pulp cells (RPC-C2A) and human lung fibroblasts (MRC5). Samples of the adhesives were light-cured and placed in culture medium for 24 hours. The extraction media was applied on the RPC-C2A and the MRC5 cells. Complete medium was used as a control. Cytotoxicity was evaluated with a modified sulforhodamine B (SRB) assay after 24 hours of exposure.Results: The cell survival of RPC-C2A cells exposed to Fuji Bond LC, NanoBond, Clearfil Liner Bond 2V, ED Primer II, Admira Bond and Gluma Comfort Bond was 73%, 67%, 50%, 20%, 18% and 5% respectively, relative to the cell survival with the control medium. In the MRC5 cell line, the relative survival was 98%, 80%, 72%, 41%, 19% and 7% after exposure to NanoBond, Fuji Bond LC, Clearfil Liner Bond 2V, ED Primer II, Admira Bond and Gluma Comfort Bond, respectively.Conclusions: Different types of dental adhesives showed different cytotoxic effects on cells in vitro. The self-etch adhesives were superior in terms of cytotoxicity. The different cytotoxic effects of dental adhesives should be considered when selecting an appropriate adhesive for operative restorations. (Eur J Dent 2009;3:3-9)

ABSTRACTAnatomical variations must be considered in clinical and radiographical evaluations during endodontic treatment. Access cavity modifications may be required for stress free entry to complex anatomy. Higher magnification and illumination can be useful for access cavity preparation and to recognize and locate additional canals. This article describes the diagnosis and clinical management of two clinical cases of three rooted maxillary premolars. (Eur J Dent 2009;3:62-66)
Double Dens Invaginatus: Report of Three Cases
Authors: Zengin A. Zeynep , Sumer A. Pinar , Celenk Peruze 
Published: September 2019

ABSTRACTDens invaginatus results from an infolding of the outer surface of a tooth. The clinical importance of dens invaginatus results from the risk of pulpal disease. So, all clinicians should be aware of
this anomaly. The presence of double dens invaginatus is extremely rare. This article presents three cases of double dens invaginatus in permanent maxillary lateral incisors, one with preventive restoration on its palatal surface. They were classified as double dens invaginatus because of two enamel lined invaginations presented in the crowns of these teeth. (Eur J Dent 2009;3:67-70)

Published: September 2019

ABSTRACTObjectives: The aim of this study was to investigate the presence of Treponema denticola in symptomatic apical periodontitis and in symptomatic apical abscesses by real-time polymerase chain reaction (PCR) method.Methods: Microbial samples were collected from 60 single-rooted teeth having carious lesions and necrotic pulps. For each tooth, clinical data including patient symptoms were recorded. Teeth were categorized by diagnosis as having symptomatic apical periodontitis or symptomatic apical abscess. Aseptic microbial samples were collected using paper points from 30 infected root canals and from aspirates of 30 abscesses. DNA was extracted from the samples by using a QIAamp® DNA mini-kit and analyzed with real-time PCR.Results: T. denticola was detected in 24 of 30 cases diagnosed as symptomatic apical abscesses (80%), and 19 of 30 cases diagnosed as symptomatic apical periodontitis (63.3%). In general T. denticola was found in 43 of 60 cases (71.6%).Conclusions: Our findings suggest that T. denticola can participate in the pathogenesis of symptomatic apical abscesses.

Published: September 2019

ABSTRACTObjectives: To evaluate the effects fluorosis and self etching primers (SEP) on shear bond strengths (SBS) of orthodontic brackets.Methods: A total of 48 (24 fluorosed and 24 non-fluorosed) non-carious freshly extracted human permanent premolar teeth were used in this study. Fluorosed teeth were selected according to the modified Thylstrup and Fejerskov index (TFI), which is based on the clinical changes in fluorosed teeth. Fluorosed and non-fluorosed teeth were randomly assigned to 4 groups of 12 each. In groups I (non-fluorosed teeth) and II (fluorosed teeth), standard etching protocol was used and brackets were bonded with Light Bond. In groups III (non-fluorosed teeth) and IV (fluorosed teeth), Transbond Plus SEP was used and brackets were bonded with Transbond XT Light Cure Adhesive. All specimens were cured with a halogen light. After bonding, SBS of the brackets were tested with Universal testing machine. After debonding, all teeth and brackets in the test groups were examined under 10x magnifications. Any adhesive remained after debonding was assessed and scored according to the modified Adhesive Remnant Index (ARI).Results: ANOVA indicated a significant difference between groups (P<.001). SBS in group II (Light Bond+Fluorosis) were significantly lower than other groups. ARI scores of the groups were also significantly different (P<.001). There was a greater frequency of ARI scores of 1,2 and 3 in group II (Light Bond+Fluorosis).Conclusions: When standard etching protocol was used enamel fluorosis significantly decreased
the bond strength of orthodontic brackets. Satisfactory bond strengths were obtained when SEP was
used for bonding brackets to the fluorosed teeth. (Eur J Dent 2009;3:173-177)

Authors: Pitak-Arnnop Poramate , Chaine André , Dhanuthai Kittipong , Bertrand Jacques-Charles , Bertolus Chloé 
Published: September 2019

ABSTRACTAmeloblastic fibroma (AF) is a rare odontogenic tumour of the jaw which usually occurs in the first 2 decades of life. The common clinical manifestation is a slow-growing swelling. We report a case of a 16-year-old male patient presenting with extensive AF of the mandible. He underwent a conservative enucleation. The tumour recurred 2 years after the initial surgery, requiring the second enucleation.The patient has continued to be followed closely and has been disease-free for 4 years. Recent evidence suggests that the recurrent rate of AF is relatively high, and malignant transformation of AF may occur after recurrences or multiple surgeries. A conservative treatment approach with close surveillance is recommended. Anatomical limitations should be taken into account, especially when enucleation of AF in the posterior portion of the jaw is performed. Current surgical pathologic issues of the tumour are also discussed. (Eur J Dent 2009;3:224-228)

Published: September 2019

ABSTRACTObjectives: To examine histological aspects of the ligaments between the middle ear and temporomandibular joint and suppose a theoretical role of their structural characteristics on mobility of mallear ossicle.Methods: The ligaments were obtained by microdissection of middle cranial fossa on both sites of 15 cadavers fixed in formalin solution and were sectioned longitudinally (7-10 µm thickness). The sections were stained with Verhoff’s Van Gieson’s stain (VVG) for demonstration of elastic fibers and visualized at X2.5 and X10 magnifications under light microscopy.Results: Anterior mallear ligament (AML) and sphenomandibular ligaments (SML) were consisted of collagen fibres in analyzed specimens. The discomallear ligament (DML) was constituted
of rich collagenous fibres. One specimen of DML harvested between petrotympanic fissure and
retrodiscal-capsular intersection site contained elastic fibers dispersed in cotton-bowl appearance between collagen fibers. In the light of functional tests performed in previous studies, it could be extrapolated that presence of elastic fibers in the DML may prevent excessive forces conducted to mallear head by elongation of elastic fibers.Conclusions: Collagenous fibres have no ability to stretch along their axis which may lack compensatory mechanism to prevent mallear head mobility.

Published: September 2019

ABSTRACTObjectives: The aim of this study was to evaluate the bond strength of one-step adhesive systems to dry or moist dental substrate.Methods: Thirty human third molars were sectioned into two halves, in the mesio-distal direction, parallel to the long axis of the tooth. Each half was embedded in a polystyrene resin cylinder so that the buccal/lingual surface remained exposed. This exposed surface was abraded to obtain both flat exposed enamel and dentin. The samples were randomly allocated according to the adhesive system (Xeno III, Adper Prompt and iBond) and moisture condition (dry and moist). The substrates were air-dried for 30 s for dry condition, while the moist substrates were re-wet with 2.5 µl of distilled water after drying. After the adhesive procedures, two resin composite cylinders were build-up on dentin and enamel substrates, totaling four per sample. A shear load was applied to the samples at a crosshead speed of 0.5 mm/min until failure. Data were statistically analyzed by three-way ANOVA and the Tukey test (α=0.05).Results: The evaluated one-step adhesives showed higher bond strength to dentin than enamel. The iBond presented better bond performance to moist substrate and Xeno III to dry substrate. The moisture condition did not interfere in the performance of Adper Prompt. The Xeno III and iBond presented higher bond strength than the other adhesives to both dry and moist substrates.Conclusions: The moisture condition of substrate interfered in the performance of one-step selfetching adhesives and the best moisture condition was material dependent.

Authors: Dogan Alev Aksoy , Bolpaca Pinar 
Published: September 2019

ABSTRACTObjectives: High intake of fluoride (>1.5 mg/L) for a prolonged period may lead to skeletal fluorosis as well as dental fluorosis. The aim of this study was to compare the craniofacial characteristics of children with dental fluorosis in early permanent dentition period to those without fluorosis.Methods: Two hundred and sixteen children in early permanent dentition (girls:121, boys:95)
were included in the study. Study group was composed of 124 children with dental fluorosis who
was born and grew up in Isparta (girls:75, boys:49) whereas control group of children (n=92: 46 girls and 46 boys) had no dental fluorosis. Dental fluorosis was classified using Thylstrup Fejerskov Fluorosis Index. Radiological evaluation was performed by cephalometric tracing using Björk analysis. Statistical evaluation in between study and control groups was done by Independent Samples T test and comparison with Björk’s standards was done by One Sample T test analysis. The association between two quantitative variables was evaluated with Pearson’s correlation coefficient (rho).Results: The mean dental fluorosis level was 4.6±1.8 for children with fluorosis. Systemic fluorosis affect girls no different than boys in the early permanent dentition period because none of the angular measurements show significant difference between boys and girls in the fluoridated group. Comparison of craniofacial angular values of boys with fluorosis show greater diversity compared to boys without fluorosis against Björk’s mean values for boys.Conclusions: Craniofacial morphology of children with fluorosis did not show great diversity than the ones without fluorosis in the early permanent dentition period. None of the angular measurements were significantly different between boys and girls in the fluoridated group which might imply that systemic fluorosis did not show gender difference in the early permanent dentition.

Published: October 2019

Abstract
Objective The main objective of this article was to evaluate vincristine neuropathy effect on common peroneal and tibial nerves.
Methods A retrospective study was conducted in children with vincristine neuropathy between August 2006 and January 2016 at Sultan Qaboos University Hospital.
Results Twenty-eight children (15 females and 13 males) were included in the study. The compound muscle action potential of common peroneal nerves was significantly reduced relative to the tibial nerves (p < 0.05)). There was no difference in latency and nerve conduction velocity between the two nerves.
Conclusion Children receiving vincristine demonstrate severe peroneal neuropathy compared with tibial nerves. We conclude that squatting posture effects peroneal nerves and postulate that the peroneal nerves are affected more due to the squatting posture. This squatting posture stretches the nerves that are already affected by the toxic effect of vincristine.

Published: September 2019

AbstractThe purpose of this study is to determine the influence of debridement in and around the bone tunnels on the prevalence of cyclops lesion (CL), after anterior cruciate ligament reconstruction (ACLR) with hamstring grafts. Our hypothesis was that bone tunnel debridement during ACLR would reduce the prevalence of CL. Methods for debridement in and around the bone tunnels after tunnel drilling were standardized and applied to 38 knees undergoing double-bundle ACLR between 2011 and 2014, Group A (debridement group). Group B (nondebridement group) included 56 knees in which bone tunnel debridement was not performed. Postoperative MRI was performed to evaluate the presence of CL and the following three criteria: (1) the intercondylar site of CL (grade 1–3), depending on its anterior extent along the femoral condyle; (2) posterior bowing of the ACL graft; and (3) the positional relationship between the frontmost fiber of ACL graft and Blumensaat's line. If CL caused loss of extension or pain or discomfort during knee extension, it was defined as symptomatic CL (SCL). CL was detected in 8 cases (21.1%) in Group A and 26 cases (46.4%) in Group B. The prevalence of CL was significantly lower in Group A than in Group B (p = 0.010), and the risk ratio of CL was 0.31 (95% confidence interval: 0.12–0.79). Furthermore, 10 patients in Group B had SCL, compared with none in Group A (p = 0.004). In Group A, the intercondylar site of CL was grade 1 in all cases, while in Group B, the CL grades were 1 (n = 17), 2 (n = 7), 3 (n = 2) (p = 0.008). There were no cases of posterior bowing of the ACL in Group A, but six cases in Group B (p = 0.023). Debridement in and around the bone tunnel is a simple and effective method of preventing CL and SCL after ACLR. The level of evidence for the study is 3.
