True or False: The life span of conventional crown and bridge is reported at 74% for 15 years.

• A. True
• B. False
• C. Only partially true
• D. Depends on the type of material used

Answer: (A)

The statement that the life span of conventional crown and bridge is reported at 74% for 15 years is based on clinical studies and research in dentistry that track the longevity of these restorative dental components. A survival rate of 74% indicates that a little over two-thirds of these restorations remain intact and functional after a significant period of 15 years. This statistic reflects the durability and effectiveness of conventional crown and bridge work, which is widely utilized in restorative dentistry. In evaluating this statement, it is important to recognize the impact of various factors such as the individual patient's oral hygiene, the placement technique, and the material used in the restorations. While these factors can influence longevity, the specific figure of 74% has been used in dental literature to denote a general expectation regarding the longevity of these restorations. Hence, asserting the truth of the statement is consistent with those findings in dental research.
