Impaction denotes a tooth failing to attain its normal position to reach the occlusal table with third molars impaction being common in the mandible. The conventional radiographic views such as peri-apical, panoramic radiograph are two dimensional representations of three dimensional structure. Absence of information on relation of vital anatomical structures to impacted teeth, bone quality is a drawback for the operating surgeon which could lead to pre or post operative complications. CBCT imaging fills the lacunae of two dimensional imaging and holds a key role in impaction assessment.A retrospective analysis of 45 patients who underwent CBCT imaging prior to extraction of impacted third molars were included in the study and the data was analysed using SPSS.Among the 45 patients, 20 were males (44.4%) and 25 were females (55.5%) and the age group commonly affected with impaction was between 25-30 years (35.5%).The frequency of impacted third molars was more in mandible (80.0%) compared to maxilla (20%).There was significant correlation between nerve involvement and angulation of impacted third molars.CBCT imaging modality provides a three dimensional view to help in better treatment planning, anticipating possible complications post surgery. CBCT must be recommended as the only imaging modality in impaction assessment.

Introduction: Lichen planus, is a chronic autoimmune, mucocutaneous disease affecting the oral mucosa besides the skin, genital mucosa, scalp and nails.The exact etiology of oral lichen planus is unknown. The disease most commonly affects middle-aged females. Oral lichen planus usually presents as white striations (Wickham's striae), white papules, white plaque, atrophic , ulcerative, erosive or as blisters. There is a well established correlation between oral lichen planus and liver disease. Opinion amongst researchers vary on terminology of lichen planus and lichenoid drug reaction . Recent literature reported association between lichen planus and thyroid disease.
Aim: The main aim of this study is to evaluate the association between oral lichen planus and thyroid disease and its prevalence amongst patients visiting our dental institute.
Materials and methods: 67 case sheets of patients, diagnosed with oral lichen planus between June 2019 and March-2020 were retrieved from the electronic database . Collected data were entered into the Excel sheet and was analysed using SPSS analysis.
Results: Results showed a positive association between oral lichen planus and thyroid disease, mainly hypothyroidism (7.46%). Females were more affected than males (53.7%).The erosive variant of oral lichen planus was more prevalent among the study population (44.7%). There was a positive correlation between predominant clinical variety of Lichen planus and site involved. The positive correlation between hypothroid state and lichen planus is also reported.
Conclusion: In conclusion, our study establishes an association between oral lichen planus and a coexisting thyroid disorder mainly hypothyroidism .
