Abstract: This article reviews the literature regarding factors that affect proximal contact tightness (PCT) when restoring Class II cavities with direct composite resin. The PCT between two adjacent teeth is an important factor in maintaining oral health by ensuring that tooth positions remain stable, food is deflected away during mastication, dental papillae are maintained and to facilitate hygienic cleaning. If open contacts are created, there is a greater chance that the patient will experience periodontal problems or caries. Using sectional matrix systems with separation rings, and using materials with less polymerization shrinkage are effective methods to increase PCT and create significantly tighter contacts compared with using circumferential matrix systems.

Clinical relevance: Understating the clinical factors that affect proximal contact tightness between adjacent teeth is important to achieve optimal contacts in direct composite resin restorations to maintain oral health.
