Abstract

Objective: Preparation of curved canal is the ultimate challenge in endodontic treatment. Various incidents could occur during preparation such as ledges, perforations, and zip. Modification instruments have been made to avoid those incidents, can be used according to the canal shape. Reportedly, rotary reciprocating instrument can be used for curved canals because it can maintain canal shape, with or without little alignment. This case report discusses the use of a single file reciprocating system for the preparation of curved canal in the second molar left mandible.Methods: A 22-years-old male patient came to Dental Hospital Hasanuddin University complained about decay of his molar left mandible and felt pain while eating. Radiographic image   appears   normal at 37 with curved canals in mesial roots and straight canal in distal root along with thickening of periodontal ligament space. Endodontic treatment was performed with preparation of curved canals using rotary WaveOne GOLD file in mesial root and Protaper Universal in distal root. Restoration was done with metal onlay.Results: The results of the preparation maintain the curved canal shape.Conclusions: Preparation of   curved canal using a single file reciprocating system can maintain the original canal shape and bring out good result.

Abstract

Failure to detect caries early affects the effectiveness of preventive care by dentists. Early detection of caries helps dentists prepare and determine the appro-priate and accurate type of treatment based on caries risk, lesion severity, surface integrity and caries activity, in relation to the need for or absence of treat-ment without instrumentation on non-cavity lesions. Successful early detection of caries helps dentists prevent and restore teeth before more extensive da-mage occurs. Caries is one of the dental and oral health problems that needs attention. The process of caries begins with the formation of white spot lesions, which, if treated quickly, will prevent extensive damage to the tooth structure, so early detection of caries is necessary to determine the location and extent of caries. Fibre optic transillumination is a minimally invasive method that can be used to detect caries through light transmission without invasive instruments to determine the treatment plan. It is concluded that the effectiveness of caries prevention treatment can be achieved through early detection of caries. Fibre optic transillumination is a minimally invasive method for detecting caries through light transmission.
