Introduction: A thorough understanding of the relationship between periodontal tissue and prosthetic restorations is important to ensure optimal shape, function, and esthetics of restored teeth. This study aimed to assess the practice of dentists in respecting the biologic width in fabrication of prosthetic restorations.
Materials and Methods: This Analytical retrospective cross-sectional study was conducted in the school of dentistry of Guilan at 2022. This study evaluated 323 bitewing radiographs selected by convenience sampling. The distance between the restoration margin and alveolar crest in the proximal tooth surfaces was measured, and values < 2 mm were recorded as cases of biologic width invasion. All measurements were made by a digital caliper on a negatoscope. Data were analyzed by SPSS 19 and a P-value of less than 0.05 was considered statistically significant.
Results: The biologic width was within the normal range in 38% of patients; while, biologic width invasion was found in 62%. Invasion to the biologic width had no significant association with tooth type, restoration type, or jaw (P>0.05). Respecting the biologic width had a higher frequency in the maxilla (41%) than mandible (29.5%) although this difference was not significant (P=0.12).
Conclusion: Considering the biologic width invasion in 62% of the assessed cases and its consequences, the present results highlight the need for further instruction of dentists in this regard.
