The aim of the study was to evaluate the advantages and disadvantages of bulk-fill type fillings realized with SONICFill™ over an 18 month interval, on a batch of patients with different ages and occupations. Materials and methods: the study was performed on a batch of 73 patients who addressed the Clinical of Odontology- Endodontics within the Platform of Practical Training (PIP) of the Faculty of Dental Medicine of the ”Apollonia” University of Iaşi, between Octomber 1, 2014 – May 1, 2016, subjected to 91 bulk-fill fillings with SonicFill™ on the posterior teeth. Results and discussion: out of the total number of 73 patients, 56 came from the urban environment, and 17 – from the rural medium, the highest ratio being represented by the 21-30 year age group (45%), closely followed by the 31-40 year one (40%). As for gender distribution within the batch, nearly two-thirds are women, the rest being men. The education level influenced patients’ decision – that of accepting a new method of filling application. As to the types of teeth to which restorations were applied, the highest ratio is represented by lower molars (41%), followed by upper molars (23%) and mandibular premolars (20%), the lowest number of restorations being applied to maxillary premolars. Out of the total number of 91 bulk-fill restorations, 28 were applied over a base filling while, in 63 restorations, the basic filling was absent. Conclusions: The SonicFill ™ system for bulk-fill posterior restorations has a number of advantages, such as: high photopolymerization depth, significant reduction of setting contraction, better composite adaptation to the cavity walls, long-term predictable clinical results.
