Skleroderma’lı Hastaya Multidisipliner Yaklaşım ve 2 Yıllık Takip: Olgu Raporu. [Multidisciplinary approach to scleroderma patient and 2-year follow-up: A case report].

Case Report ADO Klinik Bilimler Dergisi, Volume 4, Issue 4, 2011, Pages 720-724

Abstract

Scleroderma is a chronic disease which is characterized by vascular deformities and fibrous changes of the mucocutaneous surfaces and viscera due to the increased deposition of extracellular matrix in connective tissue. Scleroderma often affects oral and perioral tissues presenting very characteristic features like tongue rigidity, narrowing of oral aperture and xerostamia. This case report presents an interdisciplinary approach to a molar tooth of a systemic sclerosis patient who had a limited oral aperture. At present root canal treatment and fixed partial dentures appear to be the treatment of choice for the patient with systemic sclerosis because two year clinical follow-up is free of complaint.

Modeling fluoride recharge profiles of restorative materials.

Conference Paper 4thCongress of Conseuro, Seville, SPAİN, Volume -, Issue -, 2009, Pages -

Abstract

Introduction and objectives: The aim of this study was to compare various fluoride containing restorative materials’ recharging capacities following topical fluoride applications by using linear regression analysis. Materials and methods: Specimens’ intrinsic fluoride amounts into artificial saliva for six weeks were determined. Then the same specimens were divided into six subgroups and various topical fluoride treatments were applied. Re-released fluoride amounts were determined using an ion selective electrode and the data were statistically analyzed by using linear modeling technique. Results and discussion: Materials were found to be recharged with the applied topical fluoride treatments at different rates. The highest amount of fluoride was re-released by the material which had got the highest intrinsic fluoride release. Although the released fluoride amounts of the materials after recharge were different, their re-release profiles were found to be similar in which the release was initially fast and became slower in time. Conclusions: It was concluded that more than the applied topical applications’ types, the frequency of the applications was a more important factor for obtaining optimum recharging ability of a material. Single linear modeling approach produces exact results and precise inference as well as it provides simplicity in calculations.

Prevalence of dental development anomalies in a Cypriote adult population in Northern Cyprus

Conference Paper FDI Annual World Dental Congress, Salvador Da Bahia, BRAZİL., Volume -, Issue -, 2010, Pages -

Abstract

The purpose of this study was to investigate radiographically the prevalence of developmental disturbances in tooth formation in patients admitting to the Dental Faculty of Near East University of Cyprus. There have been no previously reported dental records and epidemiologic data available for this population. A retrospective study based on the examination of panoramic radiographs of 4672 patients aged 16 to 82 years between January 2007 and February 2010 was performed. Codes of International Classification for Diseases (ICD) were used for the selection and coding of disturbances in tooth formation. Rates of observation of any anomaly with respect to gender, age and alpha-thalassemia were analyzed using the Pearson chi-square test (p?0.05). Dilaceration was the most commonly observed anomaly (26%) in this study according to the category of tooth formation disorders among dental anomalies. Hypersementosis was detected in a smaller number of radiographs. Although larger samples are required to effectively determine the complete description of disturbances in tooth formation, no dental anomalies were more commonly found in this ethnic group, compared with previously published data, which may be considered to be specific to this population according to this preliminary study

The effect of home bleaching agents on the surface roughness of five different resin composites.

Conference Paper 5th Congress of Conseuro, İstanbul, TURKEY., Volume -, Issue -, 2011, Pages -

Abstract

Objectives: The aim of this study was to investigate the effects of hydrogen peroxide (HP) and carbamide peroxide (CP) on surface roughness of resin composites. Materials and Methods: Thirty specimens of five resin composites were fabricated using a round matrix (1mm thick, 10 mm in diameter). Each composite group was equally divided to 3 subgroups as control, CP and HP. Baseline surface roughness (Ra) value of each specimen was measured with a profilometer (Mahr Perthometer M2). 10% HP (Opalescence Treswhite, Ultradent) and 10% CP (Opalescence PF, Ultradent) were applied according to manufacturers’ instructions and Ra measurements were repeated at the end of 10 days. Data were analyzed with Kruskal-Wallis and Mann-Whitney U tests. Results: Ra values of composite groups exposed to bleaching agents were statistically higher than control group (P<0.05). There was no significant difference between Ra values after HP and CP application within each composite group. Ceram-X Mono revealed the lowest Ra values (P<0.05) however no statistically significant difference was found among the other composites. Conclusions: Home bleaching agents increased the surface roughness of all composites. CP and HP were not superior to each other in terms of surface roughness. It may be suggested that ceramic content of Ceram-X mono was effective on the Ra values. Clinical Relevance: Home bleaching agents should not be used without a clinician’s supervision. Since the rough surfaces promote plaque adhesion and staining, composite restorations should be controlled and patients should be informed that restorations may need polishing or replacing after bleaching treatment.

Color change of five resin composites exposed to 10% hydrogen perokside and carbamide perokside.

Conference Paper th Congress of Conseuro, İstanbul, TURKEY, Volume -, Issue -, 2011, Pages -

Abstract

Objectives: This study was conducted to determine the effect of hydrogen peroxide (HP) and carbamide peroxide (CP) on color change of different composite resins. Materials and Methods: A round metallic matrix was used to fabricate composite specimens of each brand (Reflexions, Grandio, Gradia Direct, Clearfil Majesty Esthetic and Ceram-X Mono). Each composite group (n=20) was equally divided to 2 subgroups as CP and HP. Baseline CIE L*a*b* color parameters of specimens were measured on neutral grey background with a spectrophotometer (Easyshade Compact, Vita). 10% HP (Opalescence Treswhite, Ultradent) and 10% CP (Opalescence PF, Ultradent) were applied according to manufacturers’ instructions and color measurements were repeated at the end of 10 days. CIE L*a*b* parameters were analyzed with paired t-test and color differences (?E) were analyzed with one-way ANOVA. Results: The results of this investigation showed that bleaching agents changed the color of resin composites. Bleaching agents increased the a* parameter and decreased the b* parameter whereas did not affect the L* parameter of resin composites statistically (P<0.05). All ?E values were >3.5. The highest ?E values were observed in Ceram-X Mono (P<0.05). There was no significant difference between ?E values after HP and CP application within each composite group. Conclusions: Both CP and HP application caused a clinically unacceptable color difference in all composite resins by changing a* and b* color parameters. Clinical Relevance: Patients should be advised that home bleaching agents may cause color change in composite resins that would demand replacement of restorations.

Comparative evaluation of translucency characteristics of five different resin composites.

Conference Paper 17th Congress of the Balkan Stomatological Society, Tirana, ALBENİA., Volume -, Issue -, 2012, Pages -

Abstract

Aim: The purpose of this study was to compare the translucency characteristics of three different shades of five resin composites. Methods: Seven resin discs measuring 10 mm in diameter and 1mm thick were prepared from each brand (Grandio, Gradia Direct, Clearfil Majesty Esthetic and Ceram-X Mono, Filtek Z250) and each shade (A1,A2,A3). Baseline CIE L*a*b* color coordinates of specimens were measured in a custom made viewing booth with D65 illumination on standard white and black background by a spectrophotometer (Easyshade Compact, Vita). The translucency parameter (TP) was calculated for each resin composite and each shade. Results were analyzed using one-way ANOVA and Tukey’s test. Results: For all shades (A1, A2, A3) Ceram-X Mono showed the lowest translucency and Grandio presented the highest translucency. Grandio and Gradia were significantly more translucent than Clearfil Majesty Esthetic, Ceram-X Mono and Filtek Z250 for A1 shade (p<0.05). For A2 shade, TP values of Grandio, Gradia and Clearfil Majesty Esthetic were statistically higher than Filtek Z250 and Ceram-X Mono (p<0.05). For A3 shade, Grandio was statistically the most translucent resin composite among all resin composites. There was no statistical difference between TP values of Clearfil Majesty Esthetic and Gradia and they were significantly more translucent than Filtek Z250 and Ceram-X Mono for A3 shade (p<0.05). Conclusions: The results of this study revealed that translucency characteristics of resin composites were influenced by the brand in each shade. These changes of translucency parameters may have been due to the differences in filler and organic matrix composition. Information on the relative translucencies of different composites can be very useful for the clinicians in selecting the correct composite for the achievement of optimal esthetic results.

The effect of saliva decontamination methods on the micro-shear bond strength of one-bottle adhesive system to Er,Cr:YSGG laser pretreated dentin. [Poster].

Conference Paper International Laser Congress, İstanbul, TURKEY., Volume -, Issue -, 2014, Pages -

Abstract

Purpose: This study was conducted to evaluate the effect of saliva contamination and decontamination methods on the micro-shear bond strength of a one-bottle adhesive system to Er,Cr:YSGG pretreated dentin. Materials and Method: Thirty caries-free human molars were sectioned horizontally with a diamond saw to expose 1 mm thick dentin discs. These dentin surfaces were irradiated with Er,Cr:YSGG laser (Waterlase MD, Biolase, Irvine, CA, USA) on hard tissue mode with a MG6 sapphire tip at an energy level of 2 W, a repetition rate of 20 Hz with 55% water and 65% air for 30 s. The specimens were randomly divided into 6 groups according to decontamination methods as follows: (1) no contamination, control group, (2) contamination after laser application, (3) decontamination with water-spray for 30 seconds, (4) decontamination with air-blown, (5) reapplication of laser after contamination, (6) decontamination with microbrush. In order to test the micro-shear bond strength of one bottle adhesive system, plastic cylindrical molds with an internal diameter of 0,7 mm and a height of 1 mm were used to place composite resin on dentin disks. Three resin cylinders were attached on each dentin surface and 15 specimens were made for each group. Micro-shear bond strength was measured at a cross-head speed of 1 mm/min using an universal test machine. Data were statistically analyzed. Results: All decontamination groups showed significiantly lower micro-shear bond strengths in comparison to control group except the reapplied laser group (p<0.05). Among the decontamination groups, reapplied laser group demonstrated the highest bond strength, while decontamination with water-spray and microbrush groups showed the lowest bond strengths (p<0.05). Conclusion: Within the limitations of this study, it can be concluded that saliva contamination significiantly reduced the microshear bond strength between one-bottle adhesive system and Er,Cr:YSGG pretreated dentin. To improve the bond stength of the adhesive, Er,Cr:YSGG laser should be reapplied after saliva contamination.

The Effect of Er,Cr:YSGG Laser Application on the Micropush-Out Bond Strength of Fiber Posts to Resin Core Material. [Poster].

Conference Paper 38th Annual Conference of The European Prosthodontic Association, İstanbul, TURKEY., Volume -, Issue -, 2014, Pages -

Abstract

Objectives: The aim of this study was to compare the effects of different surface treatments including Er,Cr:YSGG laser application on the micropush-out bond strengths between glass and quartz fibre posts and composite resin core material. Methods: Thirty two quartz (DT Light, Bisco) and 32 glass fibre posts (Cytec Blanco, Hahnenkratt) with a coronal diameter of 1.8 mm were randomly divided into 8 groups according the surface treatments applied; Gr 1 (control; no surface treatment), Gr 2 (24% H2O2 for 1 min), Gr 3 (CH2Cl2 for 1 min), Gr 4 (9 % hydrofluoric acid for 1 min), Gr 5 (sandblasting with 50µm Al2O3), Gr 6 (1 W), Gr 7 (1.5 W) and Gr 8 (2 W) Er,Cr:YSGG laser irradiation. The resin core material (LuxaCore® Z Dual, DMG, Hamburg, Germany) was applied to each group and then 1 mm thick discs (n=12) were obtained for the micropush-out test. Data were statistically analyzed. Results: For quartz fibre post group, all surface treatments showed significantly higher micropush-out bond strengths in comparison to control group (p<0.05), except for 2 W Er,Cr:YSGG laser group. For glass fibre post group, H2O2, CH2Cl2, Al2O3, and laser application (1 W, 1.5 W) (p<0.05) enhanced the bond strength between the post and core material however, hydroflouric acid group showed the lowest bond strength values. Conclusion: The type of post and surface treatment might affect the bond strength between fibre posts and resin core material. 1 W and 1.5 W Er,Cr:YSGG laser application improved adhesion at post/core interface. Clinical significance: The type of fibre post should be considered in selection of surface treatment. High concentration or long application time of hydroflouric acid may decrease the bond strength of glass fibre posts. 1 W and 1.5 W Er,Cr:YSGG laser application can be recommended as a surface pretreatment for both quartz and glass fibre post.

Original Article Selçuk Üniversitesi Dişhekimliği Fakültesi Dergisi, Volume 20, Issue 1, 2011, Pages 40-50

Abstract

Background: The aim of the present study was to determine radiographically the prevalence of developmental abnormalities of size and form of teeth in patients attending the Dental Faculty of Near East University of Cyprus and to evaluate the relationship between gender differences and these anomalies. There are no previously reported dental records and epidemiologic data available for this population. Methods: A retrospective study based on the panoramic radiographs of 4672 patients aged 16 to 82 attended from January 2007 to February 2010 was performed in this population. Radiographs were studied in detail for the presence of possible dental anomalies with 9 examiners. International classification for diseases (ICD) codes was used for the selection and coding of dental anomalies. Differences in incidence rates of each dental anomaly by gender and age were analyzed by using the Pearson chi-square test (P?0.05). Results: The more common anomalies were microdontia (% 18,7), taurodontism (% 17,1), and dens invaginatus (% 12,5). Macrodontia, were detected in a few radiographs (% 3,5). When the dental developmental anomalies where examined according to gender with the Pearson Chi-square test (p?0.05); it was found that there was no statistically significant differences between female and male patients regarding abnormalities of size and form. Conclusions: Although larger samples are required to effectively determine the complete description of abnormalities of size and form of teeth, no dental anomalies were found to occur more commonly in this ethnic group, compared with previously published data, which may be considered to be specific to this population according to this preliminary study.


Özet

Amaç: Bu çalışmanın amacı, KKTC, Yakın Doğu Üniversitesi, Diş hekimliği Fakültesi’ne başvuran hastalar arasında dişlerde görülen gelişimsel şekil ve boyut anomalilerinin yaygınlığını radyografik olarak incelemek ve anomaliler ve cinsiyet arasında herhangi bir korelasyon olup olmadığını değerlendirmektir. Bu popülasyon için bu konuda daha önce kaydedilmiş diş hekimliğine dair herhangi bir kayıt veya epidemiyolojik veri bulunmamaktadır. Gereç ve Yöntemler: Ocak 2007-Şubat 2010 tarihleri arasında yaşları 16-82 arasında değişen 4672 hastanın panoramik radyografileri retrospektif olarak incelenmiştir. Radyografiler olası şekil ve boyut anomalilerinin saptanabilmesi için 9 araştırmacı tarafından taranmıştır. Dental anomalilerin seçimi ve kodlanmasında uluslararası hastalık sınıflandırması (ICD) kodları kullanılmıştır. Her bir dental anomalinin cinsiyet ve yaş açısından görünüm oranları Pearson ki-kare testi ile değerlendirilmiştir (P?0.05). Bulgular: Bu popülasyonda mikrodonti (% 18,7), taurodontism (% 17,1), ve dens invaginatus (% 12,5) en yaygın gözlenen anomaliler arasındadır. Makrodonti daha az sayıda radyografide tespit edilmiştir (% 3,5). Şekil ve boyut anomalileri Pearson Ki-kare testi (p?0,05) ile cinsiyet açısından incelendiğinde; kadın ve erkek hastalar arasında istatistiksel olarak belirgin farklılığa rastlanmamıştır. Sonuçlar: Her ne kadar şekil ve boyut anomalilerinin yaygınlığının daha geniş kapsamlı değerlendirilmesi için popülasyonun daha büyük bir kısmının ileri çalışmalar ile taranması gerekli olsa da, bu öncü çalışmada daha önce çalışılmamış olan bu etnik popülasyonu, diğer popülasyonları inceleyen önceki çalışmalarda elde edilen verilerden ayıran ve bu popülasyona özgü yaygın olarak gözlenen herhangi bir dental anomaliye rastlanmamıştır.

Abstract

To determine radiographically the prevalence of developmental dental anomalies in patients attending the Dental Faculty of Near East University of Cyprus. There are no previously reported dental records and epidemiologic data available for this population. Materials and Methods: A retrospective study based on the panoramic radiographs of 4672 patients aged 16 to 82 attended from January 2007 to February 2010 was performed. Informed consent forms were obtained that the panoramic radiographs can be used for scientific studies. Radiographs were studied in detail for the presence of possible dental anomalies with 8 examiners. International classification for diseases (ICD) codes was used for the selection and coding of dental anomalies. Differences in incidence rates of each dental anomaly by gender and age were analyzed by using the Pearson chi-square test (P?0.05). Results: Hypodontia was the most common anomaly (% 14,5). Fourth molar (% 2,2) and mesiodens (% 1) were detected only in a few radiographs. Conclusions: Although larger samples are required to effectively determine the complete description of dental anomalies, no dental anomalies were found to occur more commonly in this ethnic group, compared with previously published data, which may be considered to be specific to this population according to this preliminary study.

Abstract

The purpose of this study was to investigate radiographically the prevalence of developmental disturbances in tooth formation in patients admitting to the Dental Faculty of Near East University of Cyprus. There have been no previously reported dental records and epidemiologic data available for this population. A retrospective study based on the examination of panoramic radiographs of 4672 patients aged 16 to 82 years between January 2007 and February 2010 was performed. Codes of International Classification for Diseases (ICD) were used for the selection and coding of disturbances in tooth formation. Rates of observation of any anomaly with respect to gender, age and alpha-thalassemia were analyzed using the Pearson chi-square test (p?0.05). Dilaceration was the most commonly observed anomaly (26%) in this study according to the category of tooth formation disorders among dental anomalies. Hypersementosis was detected in a smaller number of radiographs. Although larger samples are required to effectively determine the complete description of disturbances in tooth formation, no dental anomalies were more commonly found in this ethnic group, compared with previously published data, which may be considered to be specific to this population according to this preliminary study.

Abstract

Objectives: The aim of this study was to investigate the influence of salivary contamination on bond strength to dentin during different application stages of 3 different adhesive systems Materials and Methods: Twenty-four caries-free human molars were sectioned horizontally with a diamond saw to expose 1 mm thick dentin disks. Totally 48 disks (two dentin disks from each tooth) were obtained and these disks were randomly divided into 3 groups according to adhesives used (Prime Bond NT, Clearfil SE Bond, Clearfil S3 Bond). Each adhesive group was further subdivided into 4 groups according to contamination methods as follows: no contamination which was the control group, contamination before adhesive application, contamination after adhesive application and contamination after polymerization of the adhesive. Transparent plastic cylindrical molds with an internal diameter of 0.7 mm and a height of 1 mm were used to place composite resin on dentin disks in order to test the microshear bond strength of the groups Three resin cylinders were attached on each dentin surface and 12 specimens were made for each group. Data were analyzed by one way ANOVA and Tukey’s post hoc test. Results: Except when contamination occurred after the polymerization of two step self-etch adhesive, bond strength values of all groups showed statistically significant reduction compared with control groups (p<0.05). Conclusions: Within the limitations of this study, it can be concluded that, saliva contamination affects the bond strength to dentin of all adhesives used in this study and the type of adhesive and the stage of contamination can be effective on the bond strength of adhesive contaminated with saliv


Özet

Amaç: Bu çalışmanın amacı, 3 farklı adeziv sistemin farklı uygulama basamaklarında oluşan tükürük kontaminasyonunun, adeziv sistemlerin dentine bağlanma dayanımları üzerine etkisini incelemektir. Gereç ve Yöntem: Yirmi dört molar dişin kullanıldığı çalışmamızda, mikro kesit alma cihazıyla her bir dişten 2 adet olmak üzere toplam 48 adet 1 mm’lik horizontal dentin kesidi elde edilmiş ve bu kesitler, test edilen adeziv sistemin tipine göre (Prime Bond NT, Clearfil SE Bond, Clearfil S3 Bond) rastgele 3 gruba ayrılmıştır. Daha sonra her adeziv sistem için biri kontrol grubu olmak üzere tükürük kontaminasyonunun olduğu aşamaya göre (adeziv öncesi, adeziv sonrası ve polimerizasyon sonrası) 4 alt grup oluşturulmuştur. Her dentin diski üzerine 3 adet 0.7 mm çapında ve 1 mm yüksekliğinde kompozit rezin silindir yerleştirilmiştir (n=12)ve mikro makaslama test yöntemi uygulanmıştır. Veriler tek yön ANOVA ve Tukey çoklu karşılaştırma testi kullanılarak değerlendirilmiştir. Bulgular: İki basamaklı self-etch adezivin polimerizasyon sonrası grubu hariç diğer bütün grupların bağlanma dayanım değerlerinde kontrol grubuna göre düşüş saptanmıştır (p<0.05). Self-etch adezivlerde adeziv sonrası tükürük kontaminasyonu sonucu elde edilen değerler, adeziv öncesi tükürük kontaminasyonu sonucu elde edilen değerlere göre istatistiksel olarak daha yüksek bulunurken, etch and rinse adezivde bu 2 grup arasındaki farkın istatistiksel olarak anlamlı olmadığı görülmüştür (p<0.05). Sonuçlar: Tükürük kontaminasyonunun adeziv sistemlerin dentine bağlanma dayanımlarını etkilediği ve bu etkinin adeziv sistemin tipine ve kontaminasyonun olduğu basamağa göre değişiklik gösterdiği sonucuna varılabilir.

Original Article Ege Üniversitesi Diş Hekimliği Fakültesi Dergisi, Volume -, Issue -, 2015, Pages -

Abstract

INTRODUCTION: This study aimed to compare the translucency characteristics of different shades of 5 composites. METHODS: Seven resin discs were prepared from each composite (Grandio, Gradia Direct, Clearfil Majesty Esthetic, Ceram-X Mono, Filtek Z250) and shade (A1, A2, A3). Baseline CIE L*a*b* color coordinates of specimens were measured in a viewing booth with D65 illumination by spectrophotometer (Easyshade Compact, Vita). The translucency parameter was calculated for each specimen. Results were analyzed statistically. RESULTS: Grandio and Gradia were significantly more translucent than Clearfil Majesty Esthetic, Ceram-X Mono and Filtek Z250 for A1 shade. For A2 shade, TP values of Grandio, Gradia and Clearfil Majesty Esthetic were statistically higher than Filtek Z250 and Ceram-X Mono. For A3 shade, Grandio was statistically the most translucent resin among all composites. There was no statistical difference between TP values of Clearfil Majesty Esthetic, Gradia and they were significantly more translucent than Filtek Z250 and Ceram-X Mono for A3 shade (p<0.05). TP values of A3 shade of Grandio were higher than A1 shade. DISCUSSION AND CONCLUSION: Translucency characteristics of composites may be influenced by the brand in each shade. Information on the relative translucencies of different composites can be useful in selecting the correct composite for the achievement of optimal esthetic results.


Özet

GİRİŞ ve AMAÇ: Çalışmamızın amacı, 5 farklı kompozit rezinin farklı renklerinin translusensi özelliklerini karşılaştırmaktır. YÖNTEM ve GEREÇLER: Her kompozit rezinin (Grandio, Gradia Direct, Clearfil Majesty Esthetic, Ceram-X Mono, Filtek Z250) her rengi (A1,A2,A3) için 7 adet disk şeklinde örnek hazırlandı. Renk ölçüm işlemleri, D65 ampül ile aydınlatılmış bir renk ölçüm kutusu içinde spektrofotometre (Easyshade Compact, VITA) ile yapıldı. Örnekler beyaz ve siyah zemin üzerine yerleştirildi, örneğin tam ortasından 3 kez ölçüm yapıldı ve ortalama CIE L*, a*, b* değerleri kaydedildi. Örneklerin translusensi dereceleri translusensi parametresi (TP) ile değerlendirildi. Elde edilen verilerin istatistiksel analizi Tek Yönlü ANOVA ve Tukey çoklu karşılaştırma testleri ile yapıldı. BULGULAR: A1 renk gruplarında; Grandio ve Gradia’nın TP değerleri; Clearfil Majesty Esthetic, Ceram-X Mono ve Filtek Z250’den elde edilen değerlere göre istatistiksel olarak yüksek bulunmuştur. A2 renk gruplarında; Grandio, Gradia ve Clearfil Majesty Esthetic’den elde edilen TP değerleri, Filtek Z250 ve Ceram-X Mono’dan elde edilen değerlere göre istatistiksel olarak yüksek bulunmuştur. A3 renk gruplarında Grandio en yüksek TP değerine sahiptir. Grandio’nun A3 renginden elde edilen TP değerleri A1 renginden elde edilenlere göre istatistiksel olarak yüksek bulunmuştur (p<0,05). TARTIŞMA ve SONUÇ: Çalışmamızın sonuçlarına göre farklı markaların aynı renkleri translusensi özellikleri bakımından farklılık göstermektedir. Başarılı estetik uygulamalar için materyal seçiminde rezinin rengiyle birlikte translusensi özelliklerinin de dikkate alınması gerekmektedir.

Dentin Hassasiyeti ve Tedavi Yöntemleri.

Review Cumhuriyet Dental Journal, Volume 15, Issue 1, 2012, Pages 71-82

Abstract

Dentin hypersensitivity (DH) is a relatively common problem experienced in clinical dental practice. This condition has been defined as a short, sharp pain arising from exposed dentin in response to stimuli typically thermal, evaporative, tactile, osmotic or chemical and which cannot be described to any other form of dental defect or pathology. DH may ocur as a result of exposed dentinal tubules through either loss of enamel or gingival recession. Management strategies, which take into account aetiological factors and patient’s oral hygeine behaviour, should be considered before the home or in office treatment protocols. Treatment plan should include reduce fluid flow in the tubules by means of occlude exposed tubules and block the nerve response in the pulp with many desensitizing chemical agents or phyisical agents which also include lasers. The purpose of this review is to summarize the definition, epidemiology, mechanism, aetiology, diagnosis and treatment protocols of dentin hypersensitivity.


Özet

Günümüzde giderek artan bir sorun olarak karşımıza çıkan dentin hassasiyeti (DH) herhangi bir dental defekt veya patoloji ile açıklanamayan, kimyasal, termal, temas, ozmotik veya buharlaştırıcı uyarana karşı ortama açılmış dentin yüzeylerinden yayılan, kısa süreli keskin bir ağrı olarak tanımlanmaktadır. Sert doku kaybı veya dişeti çekilmesiyle dentin yüzeyinin açığa ve dentin kanallarının oral kaviteye doğru açılmasıyla DH oluşabilir. Evde veya klinikte uygulanacak tedavinin belirlenmesinden önce tedavi planı etiyolojik faktörler ve hastanın oral hijyen alışkanlıkları da dikkate alınmalıdır. Tedavi ekspoze dentin kanallarını kapatarak tübüllerdeki sıvı akışını azaltmaya ve pulpadaki sinir iletimini bloke eden desensitivite edici birçok kimyasal ya da lazerlerin de dahil olduğu fiziksel ajanların kullanımına dayalıdır. Bu derleme dentin hassasiyetinin tanımı, epidemiyolojisi, mekanizması, etyolojisi, teşhis ve tedavi protokolleri tanımlamaktadır.
