The aim of this case series was to assess the efcacy of antimicrobial photodynamic therapy in the treatment of chronic periodontitis. This case series included two subjects with Presence of pocket depth 6 mm or more with clinical attachment loss(CAL) and bleeding on probing (BOP) in minimum of 1 tooth in atleast two quadrants. After full mouth mechanical debridement (SRP), rst site received no further treatment, whereas, second site was subjected to photodynamic therapy. SRP+PDT group showed signicant improvement in (CAL) and reduction in probing depth as compared to SRP group. Therefore, it can be concluded that Photodynamic therapy has its own advantage as an adjunct to SRP in the non surgical treatment of chronic periodontitis,further research for which may be advocated

Radiology is an essential tool in the dental clinical practice as most structures harbouring disease are not visible to the naked eye. There are various entities that are generally not noticed until periapical pathology occurs. Under such circumstances, the diagnosis is difcult, as they mimic various other conditions. One of such condition is root fracture after an endodontic treatment of tooth. Vertical root fracture (VRF) usually starts from an internal dentinal crack and develops over time, due to masticatory forces and occlusal loads. Here in this paper we will discuss how we stepwise diagnostic radiographic modalities are used to see the actual cause of pain in a 60 year old male patient. Cone Beam Computed Tomography (CBCT) was done to view in 3D which revealed VRF of tooth. Throughout the paper the edge of CBCT over other diagnostic modalities is discussed till we get our diagnosis.
