Introduction: Dental follicle arises from odontogenicmesenchyme which result in tooth formation. Study aimed toestimate pathological alteration in follicle of impacted thirdmolar(ITM) in cone beam computer tomography (CBCT)and correlation with patient’s age, gender, site and angularposition.Material and Methods: Dental follicle (DF) from 80 ITMwere collected from 68 patients with follicular space ≤ 1.5 mmas measured from the CBCT. dental follicle associated withimpacted teeth were extracted and sent for histopatholicalexamination. statistical analysis was performed.Results: In 80 follicles which were evaluated for patholocalchanges were taken from patients ranging from age of 18to 50 years with a mean age of 37.5 years out if which 21were females and 19 were males. Pathological alterationwere found associated with 10 (35%) follicles which wasstatistically significant (p < 0.001). Incidence of pathologywas slightly more in females and in mandibular jaw. Lesionswere most commonly seen in jaws which were distoangularlyand horizontally impacted.Conclusion: it was concluded that radiographically normalappearing impacted teeth may be associated with variouspathology. So histopatholoic evaluation of all impacted teethis mandatory

Objectives: Oral submucous fibrosis (OSMF) is a common chronic debilitating oral health problem in India. The present study was conducted to correlate clinical staging with histopathological grading in patients of OSMF. Material and methods: The present study comprised of 50 patients of OSMF, which were evaluated for the age, sex, site, habit and clinical stage and were correlated with histological grading. Results: OSMF was reported as more in younger age group with a male predominance. Smokeless tobacco particularly arecanut and gutka showed a strong association in early development of OSMF. Conclusion:Though the present study showed no significant correlation between clinicalstaging and histopathological grading with p=0.635. This difference may be attributed toseverity and amount of fibrosis in various parts of the oral mucosa.
Résumé
Background: Concerns about toxicity of mercury and disposal of excessive mercury has led to decreased usage of mercury in dental profession but still tooth colored restorative materials are not affordable by all the classes of any society. The disposal of excess mercury has always been a matter of concern. Thus, in the present study, we attempted to evaluate a simple procedure from Rasa Shastra using lime powder, garlic and rock salt for recycling of excess mercury obtained from dental operatory. Materials and methods: The excess mercury was recycled by the standard procedure explained in Ayurveda texts (Samanya shodhana) using Sudha churna (lime powder), Lashuna kalka (paste of Allium sativum L.) and Saindhava lavanaa (rock salt). The commercially available mercury and recycled mercury was analyzed by inductively coupled plasma mass spectrometry (ICP-MS) for the detection of elements in ppm level. Results: It was found that the excess impure mercury contained 5138 ppm, 2866.1 ppm and 0.371 ppm of Silver, Copper and Tin respectively. After Shodhana, the level of silver, tin and copper were markedly reduced. Purified mercury showed a level of 119.5ppm silver, 0.5324 ppm copper and 0.3233 ppm tin. Conclusion: Samanya shodhana is a simple promising procedure which can be used for mercury recycling. The procedure doesnot require sophisticated equipments and maneuver. Further, the materials used in the procedure are easily available and affordable at low cost.
