Abstract

The study was conducted on twenty dogs from variety breeds to estimate the incidence of tumor mass and determine the risk factors of survey to cases of a year in veterinary hospital in Baghdad. The most common clinical signs were, ulceration, bleeding into lesions in addition to drowsiness, anorexia, fever and the others were depended tumor's location in dog's body like lameness, lacrimation and bloody constipation etc. The results showed 70% of the infected dogs were working with military forces and 30% of them were pet dogs and we found that the highest percentage of tumor accrued in dogs aged more than 10 years and the females recorded 60% of infection. Terrier breed had the highest percentage of infection (30%) followed by German shepherd (25%). the most tumor affected part of the body were mammary glands in females and the limbs in both gender (25% each one) and followed by the other sites, the histopathology picture had recorded seven types of malignant tumors in (skin, intestine and mammary glands) more frequent was Sequmas cell carcinoma 35% Adenocarcinoma 20%. Some dogs had more than one type of cancer, and some cases had recorded of benign tumors other cases had only transformed tissue but not cancer.

اجريت الدراسة على عشرين كلب من سلالات مختلفة مصابة بكتل ورمية في مناطق عدة من الجسم لغرض تقييم حدوث الاورام وتحديد عوامل الخطورة خلال عام في المستشفى البيطري في بغداد . كانت اكثر العلامات الظاهرةعلى الحيوان تقرح ونزف الافة الورمية فضلا عن الخمول وفقدان الشهية و الحمى , وقد تباينت العلامات توافقا مع قربها من موضع الورم مثل عرج الطرف وتدمع العين و الامساك المدمى في ورم الامعاء .. الخ. اظهرت النتائج ان ٧٠% من الكلاب المصابة كانت كلاب عاملة مع القوات العسكرية و30% منها كانت كلاب منزلية كما واظهرت النتائج بان اعلى نسبة للاورام كانت تحدث بالكلاب المسنة والتي تزيد عن ١٠ سنوات والنسبة الاقل بعمر دون السنة وقد سجلت الاناث نسبة 60% من الاصابة , كما و سجلت كلاب سلالة التيرر اعلى نسبة اصابة (30%) ثم تلتها سلالة الجيرمن شفيرد (25% ), اما اكثر المناطق عرضة للاصابة فكانت الغدة الثدية في الاناث والاطراف في كلا الجنسين بنسبة (25%) لكل منهما, ثم تلتها بقية المناطق اما الصورة النسيجية فقد سجلت سبعة انواع من الاورام السرطانية الخبيثة في كل من الاثداء والجلد والامعاء ابرزهم سرطان الخلية الحرشفية (35%) وسرطان الادينوكارسينوما(20%) وقد اصيبت بعض الكلاب باكثر من نوع من السرطان،كما وقد سجلت حالات لاورام حميدة واخرى تحولات نسيجية فقط غير سرطانية.

Abstract

Introduction: Non carious lesions are multicausal clinical status with wide diversity of prevalence among individuals and populations.Several etiologic backgrounds may simultaneously play role in the incidence of this condition. The purpose of this study was to investigate the prevalence of non carious tooth wear and to point out the strength of correlation between occlusal, incisal and cervical tooth wears and the most eminent associated clinical findings.Materials and methods: 338 patients 174 male and 164 female their age ranged from 20 to an opened range over 50 years were examined by one examiner. A comprehensive dental and periodontal examination was performed to identify presence and extension of non carious lesions by applying simplified scoring criteria for tooth wear index. Examination of hypersensitivity was performed by applying Wong-Backer faces pain rating scale. A questionnaire form included information regarding oral hygiene performance, type of tooth brush, method and frequency of tooth brushing. Dietary habits such as snakes and acidic food or drink consumption. Parafunction and smoking habit was also included. (Chi Square test) was applied to present the strength of association between tooth wear and the other variables investigated in this study.Results:A significant association was detected between the 3 types of tooth wear. These lesions are age dependent with no significant differences in their incidence between male and female. Frequency and type of tooth brush found to have a significant effect on non carious tooth wear. Furthermore, the study recorded significant relations of tooth wear to parafunction, extracted posterior teeth and gingival recession. However, no significant relation was detected between tooth wear and some other variables examined in this study such as dietary habits acid food and drink, smoking, dental caries, gingival bleeding and periodontal pockets.Conclusion: Several causes found to participate in the occurrence of tooth wear. Frequently develops under functional and parafunctional occlusal and incisal contact between the teeth in maxillary and mandibular arch that wear enamel and dentine away with age. It also weakens dental structure at the cervical portion of the teeth to wear off under the effect of tooth brushing and acid food and drink.
