Abstract

Ubiquitin C-terminal hydrolase L1 (UCH-L1), is a deubiquitinating enzyme. Certain changes in ubiquitination attribute to uncontrolled growth, leading to oncogenesis. The aim of this study was to characterize UCH-L1 expression patterns in normal looking human minor salivary gland tissues in the perilesional area of oral squamous cell carcinoma (OSCC). A retrospective study in which UCH-L1 immunohistochemical staining performed for 27 formalin fixed paraffin embedded blocks of surgically removed primary OSCC containing perilesional minor salivary gland tissues. The expression, subcellular localization, pattern of distribution, and stain intensity were assessed. UCH-L1 was immunopositive in minor salivary gland tissues of all sections. The immunoreactivity was (70.4%) detected in the cytoplasm and (29.6%) as mixed expression (cytoplasm and nucleus). UCH-L1 was predominately expressed in the ductal system (40.7%), followed by the myoepithelial cells (33.35%), while it was weakly expressed in the acinar cells; mucous (14.9%) and serous acini (11.1%). UCH-L1 expression is detectable in minor salivary glands in a perilesional area of OSCC, Although previously approved that it was absolutely absent in normal salivary gland tissues, it may activate during the course of oncogenesis and can be classified as a marker for predicting the future invasion of OSCC to adjacent minor salivary gland tissues. This study provides evidence for additional studies on the UCH-L1 expression in normal salivary glands in patients with maxillofacial tumorigenesis.

Abstract

Two potential problems commonly associated with flexible denture base material are surface roughness and the reduction of microhardness due to many reasons, rough surface can cause bacterial collection and the patient feels discomfort, and the possibility of the denture scratched when the surface hardness is reduced. The aim of this study was to evaluate the influence of Coca-cola on the surface quality of the flexible denture base material represented by the surface roughness and microhardness. A total of (10) samples were prepared for this study with the dimension of ( 40mm, 10mm, 3mm) length, width, and height respectively from thermo-plastic flexible resin (X-flexible capsules, color; K2 , size; LChina) by the conventional methods following the manufacturer instructions. The samples were immersed in Coca-cola drink for 12 days at room temperature. This period represents the average of one year of the beverage consumption, the drink has been changing daily.The samples were marked randomly and kept in special containers, and each sample has two rectangular surfaces used for the tests. One side is used for microhardness test and the other side used for the surface roughness test. The first tests were done before immersing the samples in coca-cola as control group. And after immersing the second tests were done as experimental group. In this study the data was analyzed using Independent samples (T- test). And results showed that there is no statistically significant difference in the surface roughness of the samples before and after immersing in Coca-cola (P-value > 0,05), while the microhardness test showed statistically a significant difference (P-value < 0,05) before and after immersing in Coca-cola. The surface roughness of flexible thermoplastic resin is not affected by coca-cola drink. While the levels of mirohardness showed decreasing after immersion in coca-cola drink. Therefore, the flexible thermoplastic material could be damaged if it is subjected to extra consumption of Coca-cola drink by the patient and this leads to lessen the amount of hardness by the time that could affect the efficiency of the prostheses, also could affect the mechanical

Abstract

Modified flasking technique for acrylic resin denture base at sandy stage. The uniform denture base plate wax pattern was made on the stone casts with a thickness of 3 mm. For the flow of acrylic on ridge, the necks of teeth were slight grinded from palatal or lingual surfaces toward buccal surface to allow more space. The volume of the definitive casts must be reduced as much as possiblebefore flasked in the lower part of the traditional flasks and fill with dental plaster (class II) covering the buccal, labial, incisal and occlusal surfaces of the teeth to give more support and prevent teeth migration. After curing cycle, the denture bases are carefully deflasked, the excess trimmed and polished the surfaces of the denture. Dentures processed with this procedure provides good retention and esthetic, more hygienic and comfortable for the patient than those processed with the conventional method. Giving more support and prevent teeth migration, comfortable for patient, good esthetic, give fine details of the mold and decreasing of time required for processing and finishing the cured prostheses.

Abstract

Pain during orthodontic treatment is inevitable side effect. Therefore, it is the responsibility of the orthodontist to alleviate this pain as possible. Menstrual cycle is often a painful event to female. Female is the most of orthodontic patient. Hence, study the pain perception of female to orthodontic treatment during menstrual cycle is essential. Aim: the aim of the present study is to asses, if there is change in pain perception to orthodontic tooth movement during menstrual cycle. Seventeen healthy female with regular menstrual cycle intended to receive orthodontic treatment with fixed appliances were participated in the study. Elastomeric separators were placed mesial and distal to maxillary and mandibular first molars during the menstrual and postmenstrual period respectively. Visual analog scale (VAS) was used to assess pain perception at 4 hours, 24 hours, 2nd, 3rd, 4th and 5th days after the separators were placed. Data of VAS scores were statistically analyzed. There were statistically significant increase in the pain perception level after the insertion of separators during menstrual cycle period and decrease during postmenstrual period. During menstrual cycle, female experienced higher pain perception to orthodontic tooth movement. Hence, it is better to postpone orthodontic visits for female patients to postmenstrual period.

Abstract

Tongue lesions create a significant proportion of the oral lesions, which afford approximation to oral health and general condition of the patient and may reflect the presence of many systemic diseases of an individual. Oral lesions have long been view as the first signs of many systemic disease and numerous of oral illness. The aim of this study was to determine the prevalence of various superficial tongue lesions in Iraqi population. 2500 patients attending the Department of Oral Medicine, College of Dentistry, Al-Mustansiriyah University in Baghdad, Iraq were examined for the presence of various tongue lesions during the period from October, 2013 to September, 2016. The age of the patients ranged from 9-75years with a mean age of 36.51 years. The prevalence of tongue lesions was 14.64% and the most common lesion diagnosed was fissured tongue affecting 43.7% of the subjects (160 cases). Geographic tongue was seen in 65 patients (17.7%). Coated tongue was diagnosed in 55 patients (17 %) hairy tongue was seen in 21patients (5.7 %) and ulcerations was seen in 1 patients (0.27%). Ankyloglossia was seen in 46 patients (12.5%) and scalloped tongue was seen in 10 patients (2.7 %). Varicosities were seen in 1 of the patients (0.27 %) and thrush in one patient (0.27 %). The number of occurrences of tongue lesions in the present study was not higher of than previous studies ̦ but the high prevalence of tongue lesions in this study (14.64%) specially fissured tongue(43.7%), geographic tongue(17.7%) and coated tongue (15.02%) indicate further investigations are demanded to indicate if genetic and congenital or environmental factors play a critical role.

Abstract

Diabetes mellitus plays a substantial role in the dentition and oral health. Oral manifestation identified with Diabetes mellitus may have a strong inclination to periodontal disease. This study was to assess the relation of salivary pH, flow rate, and buffer capacity with severity of periodontitis among patients with type 1 diabetes mellitus in comparison with healthy volunteers. A study was conducted on 58 volunteers (aged 18-25 years), of them 28 volunteers had type I diabetes mellitus (study group), and 30 volunteers were health persons with absence of medical conditions that could decrease salivary flow (control group) from both genders. Stimulated whole saliva was collected, salivary flow rate (ml/min), pH, and buffer capacity were measured and they examined orally to evaluate the plaque index according to Sinless and Lӧe (1964) and the calculus index according to Green and Vermillion (1964), all information recorded. There were a significant difference (p-value<0.01) in plaque index in the diabetic group in compared with heathy group, while the calculus index shown no differences. The salivary pH decreased significantly (p<0.045) in diabetic group in compared with heathy group, while other parameters (salivary flow rate and buffer capacity) had no effect. There were no differences in both genders.Periodontitis can be seen in the same severity in both genders, and in diabetic patients more than the normal individuals. The clinical indicators of periodontitis that observed in diabetic patients are more common than the normal individuals.
