The art of interdental contact point formation in Class II Black

Introduction: The art formation of interdental contact points in Class II Black lesions involves the use of targeted methodologies to establish a consistent treatment model for efficient contact point formation. Objective of the study. The aim of this study is to analyze contemporary approaches and strategies in formation of interdental contact points in Class II lesions, according to the principles set by G.V. Black. Materials and Methods: A prospective study of 15 patients at the “DENTLAND” SRL Clinic, 9 males and 6 females, aged between 20 and 45, average age of ±38 years, using exclusion criteria. Diagnosis was established based on clinical and paraclinical examinations. Paraclinical examination: transillumination, retroalveolar radiography and orthopantomography had a crucial role in determining the final diagnosis. Direct restoration methods with light-cured composite materials were employed in various obturation techniques: centripetal obturation technique and alternative oblique layering technique, along with matrix systems. Results: The research analysis revealed 15 cases, with 8 patients having caries that undermined and interrupted the marginal ridge (54%), and 7 patients with caries that undermined but did not interrupt the marginal ridge (46%). For the formation of the contact point, the Palodent Plus matrix system was used in 10 patients (67%), while the Palodent Generation I matrix system was used in 5 patients (33%). Out of the total 15 restorations, when dental floss was passed over the recently restored approximal surface, it was observed to be intact in 13 patients, while in 2 patients, dental floss was dissociated. The cause of this complication was the inability to individualize and adjust the Palodent Generation I system compared to the Palodent Plus system. Conclusions: The art of forming interdental contact points requires a modern approach using techniques and matrix systems for interdental contact restoration.
