Conflicting reports on its effectiveness has been reported in the literature. The objectives of this trial were to investigate the effect of micro-osteoperforations on the rate of space closure and on molar anchorage loss during mini-implant supported maxillary anterior en-masse retraction. A single center, parallel arm, randomized controlled trial was conducted. Sixty, male and female subjects (age range 16-25 years) having Class I bimaxillary protrusion or Class II div 1 malocclusion, who required fixed mechanotherapy with either upper 1st premolar or all four 1st premolar extractions were allocated into two groups using 11 allocation ratio. The allocation was done by block randomization method with a block size of 6. In the experimental group, 5 MOPs per side were performed only once just before the en-masse anterior retraction. Mini-screws were placed in order to obtain maximum anchorage. Impr18140). The trial was registered at www.ctri.nic.in with CTRI No- CTRI/2019/03/018140). Out of all non-communicable diseases, cancer is the leading cause of death in the 21st century. Oral cancer ranks in top ten cancers in the world and oncogenic viruses contribute to its development and are a major preventable risk factor for it. In the present study we intend to find the incidence of HPV and EBV by PCR in 108 sporadic oral cancer patients and study the clinico-pathological variables in agreement to their presence or absence. We found that the incidence of EBV in oral cancer is much higher (30/108; 27.8%) than HPV 16 (14/108; 13%) and, a complete absence of HPV 18 (0/108) was reported by real time PCR. Co-infection by EBV and HPV was reported in 5.6% cases (6/108). However, on comparing this data with the corresponding clinico-pathological cofactors (age, gender, grade of tumour, tumour size, nodal status
