RESUMO
Periodontitis has a multifactorial etiology as a result of interactions between periodontal pathogens and the host response. Due to the complex etiology and esthetic complications, the management of such patients is a challenging task. Vast arrays of treatment modalities are employed in the treatment of generalized periodontitis with varying success rates. Placental-derived tissues as allografts have recently been introduced for guided tissue regeneration in dentistry with favorable results. In this case report, successful periodontal treatment of a 25-year-old male patient with generalized periodontitis; Stage IV, Grade C, is presented with a 3-year follow-up. An interdisciplinary approach using regenerative periodontal surgery and a modified Andrew's bridge was used to successfully rehabilitate the patient. In a compliant patient with a well-structured interdisciplinary approach, questionable and hopeless teeth too can be retained over an extended period of time with no detrimental effect on the adjacent teeth.
RESUMO
AIM: To give notation for quadrants, tooth position, and the type of supernumerary teeth for both permanent and deciduous dentition. Tooth numbering provides dentists with an essential shortcut in clinical record keeping. MATERIALS AND METHODS: Three systems are favored worldwide: the Zsigmondy/Palmer system, the Universal system, and the Federation Dentaire Internationale (FDI) Two-Digit system. Histories of all tooth-numbering methods were traced and the strengths and deficiencies of each system were reviewed. The FDI Two-Digit system is widely used throughout the world, except USA, and is the only method that makes the visual sense, cognitive sense, and computer sense. CONCLUSION: On review it was noticed that all tooth notation systems in vogue have a drawback as they do not provide any information or notations for supernumerary teeth such as paramolar, distomolar, mesiodens, and fused teeth.
