Status of Serum and Salivary Levels of Superoxide Dismutase in Type 2 Diabetes Mellitus with Oral Manifestations: A Case Control Study

BACKGROUND: Type 2 Diabetes Mellitus is a very well known metabolic disorder that has reached epidemic proportions worldwide. Evidence suggests that oxidative stress increases in Diabetes Mellitus because of the excessive production of reactive oxygen species and an impaired antioxidant defence mechanism. This study estimated, compared and correlated the serum and salivary Superoxide dismutase levels in healthy subjects and subjects with Type 2 Diabetes Mellitus having oral manifestations.MATERIALS AND METHODS: In this study, serum and salivary Superoxide dismutase levels were estimated in 45 healthy subjects and 45 patients with Type 2 Diabetes Mellitus with oral manifestations.RESULTS: The mean serum and salivary Superoxide dismutase levels were significantly decreased in subjects with Type 2 Diabetes Mellitus with oral manifestations compared to the healthy subjects. Positive correlation in both healthy and diabetics was observed between serum and salivary samples.CONCLUSION: This study highlights that the abnormally high levels of oxidative stress in diabetics coupled with simultaneous decline in antioxidant defence mechanism results in complications in Diabetes mellitus. Thus exploring saliva for antioxidant markers that accurately reflect the redox status of the body is worthwhile.KEYWORDS: Type 2 Diabetes Mellitus, Superoxide dismutase, antioxidan

Status of thiocyanate levels in the serum and saliva of non-smokers, ex-smokers and smokers

Background: Use of tobacco is often implicated in the development of oral diseases. Questionable accuracy of the traditional questionnaires to assess cigarette exposure necessitates the use of biomarkers like thiocyanate which provide a definitive quantitative measure.Objective: To assess the rise in the level of thiocyanate for measurement of smoking behaviour in adults.Materials and methods: Serum and salivary thiocyanate levels were estimated in 20 non-smokers, 20 ex-smokers and 40 smokers. Smokers were divided into two groups based on the presence or absence of oral mucosal lesions.Results: The mean serum and salivary thiocyanate levels were increased significantly in smokers when compared to non-smokers and ex-smokers. The levels were not significantly different between ex-smokers and non-smokers and between smokers with tobacco related oral mucosal lesions and those without. Statistically significant correlation was seen between the serum and salivary levels of thiocyanate.Conclusion: This study highlights the high level of thiocyanate in the serum and saliva of smokers when compared to non-smokers and ex-smokers. Significant increase in thiocyanate level was also seen in saliva. Hence it can be stated that saliva can be used as a reliable, non-invasive tool to assess smoking behaviour in the population and its changes over time.Keywords: Thiocyanate, tobacco, smoking, cancer, pre-cancer

Goldenhar syndrome: Report of two cases with review of literature

Goldenhar syndrome consists of a varied group of malformations that can involve multiple systems of the body. It is believed to be a variant of hemifacial microsomia with ocular and vertebral involvement. Characteristic findings, such as hypoplasia of one half of the face, epibulbar dermoids, ear tags, and spinal cord defects, warrant the name occulo-auriculo-vertebral dysplasia. The syndrome occurs due to imbalance in cells during the blastogenesis period of embryo formation. It is found to involve the derivatives of first and second branchial arches. The condition is apparent at birth, but the phenotype can vary greatly in its severity depending on the activation and expression of the defective gene. Reported here are detailed clinical and radiographic features of two sporadic cases of Goldenhar syndrome in young males. This work mainly highlights the various theories of etiopathogenesis as well as step-wise management protocol for patients diagnosed with the syndrome

Siblings with pierre robin sequence

Pierre Robin anomalad is a syndrome characterized by cleft of the palate, micrognathia of the mandible, and glossoptosis. This syndrome can occur as an individual presentation, or it may be associated with a wide variety of syndromes and anomalies. Such patients are burdened with several problems, some obvious and some less so. The most obvious problems such as the psychological difficulties the patients will have to face due to the appearance and associated problems such as feeding and speech difficulties and serious consequences such as airway obstruction. Here, we report two cases of Pierre Robin sequence seen in the same family in two children of the same parents

Evaluation of salivary tumour necrosis factor–alpha in patients with recurrent aphthous stomatitis

Purpose Present study was undertaken to evaluate and compare the salivary levels of tumour necrosis factor alpha (TNF-α) in subjects with RAS, traumatic ulcers (TUs) in the oral mucosa and in healthy controls. Materials and Methods Present study involved 90 participants of which 30 subjects were diagnosed with RAS, 30 subjects with TUs and 30 healthy controls grouped as group 1, group 2 and group 3 respectively. Unstimulated saliva was collected from the subjects through ‘Spit Technique’ and the estimation of TNF-α was done by enzyme linked immunosorbent assay. The data collected was statistically analysed. Results Salivary level of TNF-α was significantly higher in RAS patients than in patients with TUs and healthy controls. Difference between the Salivary TNF-α level in our study groups were statistically significant (p<0.001). Conclusion Present study suggests that saliva is a convenient and ideal medium for the detection of TNF-α. Statistically significant difference in the level of salivary TNF-α between the RAS and TUs subjects as well as controls suggests the significant contribution of TNF-α in pathogenesis of RAS

Dentinogenezis imperfecta tip 2 ile ilgili sıradışı özellikler: ailesi üç kuşaktan fazla etkilenmiş iki olgu

Dentinogenesis imperfecta (DI) otozomal dominat genetik bir hastalıktır. Yüksek derecede penetrasyon ve düşük mutasyon oranına sahiptir. DI opalesant dentin ve dişlerde renk değişikliği ile karakterizedir. Dentin şiddetli yıpranmaya maruz kalabilir. Bu durumun erken tanı ve tedavisi, diğer komplikasyonların önlenmesinde ve estetik amaç için gereklidir.
