RESUMEN
Aloe vera (Aloe barbadensis) is a plant that belongs to Liliaceae family. The name Aloe derives from the Arabic word "Alloeh" meaning shining bitter substance while "vera" in Latin means true. It contains various minerals and vitamins. It has got various properties such as immunomodulatory, antiviral and antiinflammatory in nature. A. vera can play a significant role in dentistry in treatment of lichen planus, oral submucous fibrosis, recurrent aphthous stomatitis, alveolar osteitis, periodontitis, etc.
RESUMEN
BACKGROUND: Most of the clinical, epidemiological, and etiogenic studies on oral lichenoid reactions (OLRs) have been undertaken in the United States, UK, Scandinavia, and other European countries. So far, very few cohort studies on a small population have been documented from South Asian region to implicate the role of various causative agents in the precipitation of OLR. OBJECTIVES: To implicate the role of various allopathic, alternate medicinal drugs, dental materials, etc., in the precipitation OLRs; to evaluate the pattern of remission; and to estimate the time period for the remission of lesions following the discontinuance of the suspected agents in the population of Tamil Nadu. MATERIALS AND METHODS: A total of 102 patients were included, of whom 51 (mean age 43.3 years, SD 14.59) formed the study group, who possessed a positive drug history to the intake of either potential allopathic or alternate drugs or had recent dental metallic fillings/restorations, and 51 were (mean age 47.86 years, SD14.67) in the control group possessing oral lichen planus (OLP). The patients were followed up at a monthly interval period for a period of 18 months. RESULTS: Complete remission of signs and symptoms was noticed in 41 patients, partial remission in 6, no change in 2, newer lesions in 1, and flaredup lesions were observed in 1 participant in the study group. The mean onset time for lichenoid eruptions was found to be 2.5 months (SD 58.82) and the mean remission time after discontinuing the drug was 9.1 months (SD 4.7). CONCLUSION: OLR could be implicated to documented lichenoid agents like calcium channel blockers, ACE inhibitors, atarvastatin, metformin, glibenclamide, dapsone, carbimazole, silver amalgam fillings, etc.in southSouth Indian population. Furthermore, the drugs like oflaxacin, arsenical album, and yellow orpimentumwere also found to have strong implication in the precipitation of OLR. Discontinuance of the suspected agents resulted in healing in the majority of cases.

Internal resorption has been described as a resorptive defect of internal aspect of tooth. It is caused by transformation of normal pulp tissue into granulomatous tissue with giant cells which resorb dentin. Though mostly idiopathic in origin, trauma, caries and restorative procedures have also been suggested to be contributing factors of internal resorption of pulp. Most of the internal resorption cases were found on isolated individual tooth. There are few case reports on multiple root resorptions. External root resorption have been frequently associated with systemic disorders like renal diseases hyperparathyroidism, rickets etc. A rare association of multiple internal resorption of permanent teeth (including lateral incisors, canines, premolars, sparing 2 nd and 3 rd. Permanent molars and missing 35,36, 42) with elevated levels of PTH and uric acid was evident in a 28 year old female patient who presented with fracture of crowns of permanent teeth. Though many cases related to dental manifestations of chronic renal disease and internal resorption of permanent teeth have been documented in literature, there is no evidence on association of hyperparathyroidism with multiple internal resorptions of teeth.
