BETTER WITH OZONE, OR NOT? AN IN-VIVO STUDY OF OZONE THERAPY AS A PRE-TREATMENT BEFORE FISSURE SEALANT APPLICATION.

Objectives: The aim of the study was to evaluate clinical achievements of ClinproTMSealant and Teeth mate F-1 fissure sealants with or without ozone treatment as well as retention, marginal discoloration, marginal adaptation and caries formation under in-vivo conditions. Materials and Methods: The study was carried out on 166 patients whose ages differs between 9-12 and 3 different groups were formed above them according to split mouth technique, in order to evaluate clinical achievements of fissure sealants with or without ozone treatment. Group 1: ClinproTMSealant and Teethmate F-1 were applied on a total of 104 first lower permanent molar teeth which were randomly selected from 52 patients. Group 2: ClinproTM Sealant and ClinproTM Sealant following ozone treatment were applied on 112 randomly selected teeth of 56 patients. Group 3: Teeth mate F-1 and Teeth mate F-1 following the ozone treatment were applied on 116 first lower permanent molar teeth which were randomly selected from 58 patients. Based on the modified USPHS criteria, the impacts on general achievement, retention, marginal fit, marginal discoloration and caries formation on occlusal surfaces were evaluated in 3rd,6th,12th,18th months. Chi-Square Test and Fisher’s Exact Test were used for analyses of the data. Results: In Group 1; Clinpro™Sealant showed higher clinical success rates in all observation periods. Considering marginal adaptation and retention, Clinpro™Sealant group was statistically significantly different in 18th month observations. In group 2 and group 3, there was not statistically significantly difference (p>0.05) between control and experimental groups but clinical success rates of Clinpro ™ Sealant and Teetmate F-1 with Ozone Treatment were higher than the same groups without ozone pretreatment during all observation periods. Conclusion: It was determined that, ClinproTMSealant yielded more successful results than the Teethmate F-1 under in-vivo conditions. Although there wasn’t any statistically significantly difference between Group 2 and Group 3 in which Ozone as a pretreatment method before performing fissure sealant was considered, the Ozone pretreatment method’s success rates were higher clinically according to Bravo, Alpha and Charlie Scores. It seems that performing Ozone Therapy before applying fissure sealant is a successful method for preventing pit and fissure sealants, clinically

Williams-Beuren Syndrome: A Case Report

Williams syndrome is a rare neurodevelopmental disorder caused by the spontaneous deletion of genetic material from the region q11.23 of one member of the pair of chromosome 7, so that the person is hemizygous for those genes. Syndrome is a rarely genetic multisystem disorder that occurs equally in all ethnic groups and both sexes. Williams syndrome is a developmental disorder that affects many parts of the body. This condition is characterized by mild to moderate intellectual disability or learning problems, unique personality characteristics, distinctive facial features, and heart and blood vessel (cardiovascular) problems. The diagnosis of this syndrome is based on recognition of the characteristic pattern of dysmorphic facial and physical features. The diagnosis is typically suspected based on symptoms and confirmed by genetic testing. Treatment includes special education programs and various types of therapy. Surgery may be done to correct heart problems. Dietary changes or medications may be required for high blood calcium. Life expectancy is less than that of the general population, mostly due to the increased rates of heart disease. This case report presents the story of 10-year-old girl who suffers from Williams syndrome. Cardiac murmur, mental retardation, severe malocclusion problems, wide mouth, diestama, full lip, periorbital fulness, epicanthal fold, stellate iris pattern, short stature, weaknesses in retional/conceptual language and short term memory observed in this patient. In this study, patient’s salivary glands and deciduous anterior tooth were investigated by detailed diagnostic methods (USG, micro-CT). The overall purpose of this case was to diagnose dental manifestations and evaluate physical and clinical characteristics of present case with Williams Syndrome

Micro-CT Evaluation of Taurodontism in a Deciduous Molar and a Permanent Molar: Case Reports

Taurodontism is a morphological anomaly of teeth characterized with large pulp chambers and apically displaced pulpal floor.  The aim of this case report was to make a comparative evaluation by panoramic radiographies and 3D examinations to locate pulp chamber and root canal morphology of a primary mandibular first molar and the adaptation of root canal filling material of a permanent mandibular first molar, both diagnosed with taurodontism. In Case-1, a mandibular primary first molar was extracted due to physiological root resorption seen in the panoramic radiograph. The micro-CT (Bruker, SkyScan 1174, Belgium) examined the distance of the tooth a (distance between the lowest and the top point of the pulp chamber) and b (distance between the lowest point of the pulp chamber and the apical). The tooth was classified as mesotaurodont by the value of 52.91 obtained with the formula a/b x 100. In Case-2, the tooth was extracted because of the large periapical radiolucency observed in the radiography taken from the tooth which was admitted for pain and percussion tenderness. The calculation for subgroup could not be performed due to loss of the “a” value because of the cavity preparation. Although the root canal filling on the radiograph was found to be sufficient and long enough, an empty extra canal and insufficient wall adaptation of root canal filling were detected by micro-CT. Despite the fact that taurodontism can be diagnosed by 2D measurements, it is obvious that a 3-dimensional examination is necessary to obtain decisive data about the root canal cavity morphology especially for endodontic treatment and also to define prevalence and subgroups of anomalies. Although micro-CT is seen as a method that provides more detailed images, it is thought that it should be developed and supported with clinical studies in order to be valid and easy to use in clinical practice

Dental Management of Hypophosphatemic Vitamin D Resistant Rickets

Vitamin D-Resistant Rickets (VDRR) is an X-linked disease, causing mineralization disturbances of hard tissues such as bones and deciduous and permanent dentition. The dental findings of VDRR are enlarged pulp horns and chambers, defective enamel/dentin tissue, pulpitis, pulp necrosis, periapical recurrent abscesses and periapical complications without dental caries or trauma. The treatment options of this condition are extraction, endodontic approaches such as pulpotomy/pulpectomy, restorative and preventive applications. The aim of this case report is to summarize the dental clinical, radiographical, histopathological findings and treatment options of VDRR in a 4.5-year-old girl

Büyük azı-keser hipomineralizasyonu gözlenen kesici dişlerde hassasiyetin değerlendirilmesi

Klinik olarak bir veya daha fazla 1. büyük azı dişi ile birlikte keser dişlerin hipomineralizasyon gösterdiği olgular, Büyük Azı-Keser Hipomineralizasyonu BAKH olarak tanımlanır. BAKH gözlenen dişlerde farklı renkte lezyonlar gözlenebilmektedir, bunlar genellikle beyaz-krem ve sarı-kahverengi lezyonlar olarak sınıflandırılır, koyu renklenmelerin daha şiddetli hipomineralizasyon gösterdiği düşünülmektedir. BAKH görülen dişlerde hassasiyet şikayeti sık görülmektedir. Bu tip dişleri olan hastalar sıcak ya da soğuk yiyecek ve içeceklere, tatlıya hatta diş fırçalamaya bile hassasiyet gösterebilirler. Bu çalışmanın amacı keser dişlerde görülen hipomineralizasyonun rengi ile hassasiyet derecesi arasında ilişki olup olmadığının araştırılmasıdır. Kliniğimize başvuran hastalardan BAKH görülen 42 hastanın 120 adet keser dişi çalışmaya dahil edilmiştir. Hastalar, cinsiyetlerine, lezyonların renklerine beyaz-krem, sarıkahverengi ve dişlerin lokalizasyonlarına üst-alt çene göre gruplandırılmışlardır. Dişlerin, soğuk testine verdikleri hassasiyet skorları Vizual Analog Skala VAS kullanılarak kayıt edilmiştir. İstatistiksel analizler için Mann-Whitney U testi kullanılmıştır p0,05 . Kız çocukların keser dişlerindeki hassasiyetin anlamlı derecede yüksek olduğu tespit edilmiştir

Comparison of the Effectiveness of Chemo-mechanical and Traditional Caries Removal Methods in Primary Teeth Using Micro-Computed Tomography

Objective: The purpose of this study was to evaluate dentin mineral density before and after caries removal with the traditional caries removal technique and chemo mechanical method, with or without the use of caries detection dye. Our null hypothesis was that the chemo mechanical method with minimally invasive treatment would achieve an effect similar to that of conservative pediatric dentistry treatment. Forty-eight extracted human primary molar were used in this study. Materials and Methods: The two main study groups underwent treatment with the chemo mechanical and traditional methods. The teeth were then treated with chemo mechanical and traditional caries removal approach. Teeth were scanned with the same voxel sizes using micro-CT images to figure out the difference dentin mineral density and to calculate the removed (excavated) dentinal volume after chemo mechanical or traditional method application. Results: The results showed increase of cavity volume in the chemo mechanical and traditional method groups. No significant difference was found for cavity volume and dentinal carious volume in both groups (p˃0,05). The mineral density values of demineralized dentin were between 0.52-0.66 g/cm3 before caries removal, and 1.39-1.59 g/cm3 after removing caries. These values were found to be within the range of healthy dentin mineral density values again without any significant difference between groups (p˃0,05). Conclusions: In conclusion, chemo mechanical can be used effectively for removing the caries in the primary molar teeth similar to conservative treatments
