Background: Odontogenic cysts are unique in a way that they only affect the oral and maxillofacial region. The Odontogenic cysts arise from the epithelial components of the odontogenic apparatus or its remnants that lie entrapped within bone or in the gingival tissue. Even though the prognosis of the lesion is excellent, there are possibilities that the cyst may undergo a neoplastic change or may affect occlusion and eruption. It is important to determine the prevalence pattern of odontogenic cysts for proper management.
Aim: To determine the prevalence pattern of odontogenic cysts and its clinico-pathological correlation and to compare the results with the findings in the literature.
Methodology: This retrospective study included reports of 163 histopathologically diagnosed cases of odontogenic cysts from the year 2004. Clinical history and relevant data were recorded. The cases were analyzed for type of cyst, age, sex and anatomical site.
Results: The most frequent type of odontogenic cyst was periapical cyst (38.03%), followed by odontogenic keratocyst (35.6%), dentigerous cyst (10.4%), residual cyst (8.5%), orthokeratinised odontogenic cyst (4.2%), glandular odontogenic cyst (2.45%) and lateral periodontal cyst (0.6%). The most prevalent age group was 21-30 years except for residual cyst which was 31-40 years and lateral periodontal cyst which was 61-70 years. The most prevalent gender was male for all the odontogenic cysts. The most common anatomic site of the cysts was posterior mandible except for dentigerous cyst, periapical cyst and lateral periodontal cyst.

Objective:-1)To compare the intensity of light green stain as cytoplasm and nuclear fast red as nuclear stain compare with routine haematoxylin and eosin stain.2)To evaluate the accuracy of light green stain and nuclear fast red as an alternative stain used in cytology. Materials and methods: 30 buccal smears were collected from 10 healthy patients. they were categorized into 3 groups according to type stains were used. Result: this present study showed statically significant, p value >0.001.Conclusion:Several modifications have been made to improve their efficiency, There has been a rising need for efficient, accurate and less complex staining procedures is requiredKeywords

Aim: To assess the efficacy of liquid paraffin as a rehydrant for air dried buccal smear based on the nuclear and cytoplasmic details. Background: Buccal smear is useful for diagnosing Malignancy, Fungal infection, Viral infection and Vesicullobullous dermatoses. The routine practice is to wetfixthe smear and send them to the laboratory for staining and evaluation by a cytopathologist. But drying of smears is inevitable, especially when the aspirate is less and when there is improper fixation. This can cause drying artifacts. An alternative method for overcoming this problem is intentional air drying followed by rehydration. Many rehydrants have been experimented upon. The most common rehydrant being saline. The present study is done to check the efficacy of liquid paraffin as a rehydrant. Material and methods: 2 sets of 20 buccal smears were collected from the patients. One set air dried for 24 hours and the other wet fixed. Conventional pap staining was then carried out. The slides were examined by two observers for preservation of Nuclear and cytoplasmic details based on the semi quantitative scoring system. Results: Excellent nuclear details were seen in 45% of air dried smear compared to 25%in routine wet fixation. The cytoplasmic details of air dried smear and routine wet fixed smear was the same. Conclusion: Liquid paraffin as a rehydrant has shown promising results and the nuclear details were found to marginally better than in routine wet fixed smear. Air dried buccal smears can be used in routine practice especially in rural areas where there is limited access to laboratories and for mass screening.Keywords

Background: The presence of developmental anomalies on the tongue is relatively common reason that patients visit dental clinics. Diagnosis of a wide variety of developmental anomalies is an essential part of a daily dental practice.
Objective: The aim of this study was to evaluate the type and prevalence of developmental anomalies of tongue in patients in South Indian population.
Study Design: A total of 800 patients were screened for developmental tongue lesions. The developmental tongue lesions were found in 32 of 800 patients examined. The prevalence pattern was examined.
Result: The most prevalent tongue lesion was found to be fissured tongue 14(44%). The least prevalent was found to be macroglossia 1(%). The tongue lesions such as microglossia, hairy tongue and lingual nodule were not present.The developmental tongue lesions were found to be more in males (75%) than females (25%) in the survey.
