The aim of this research was to evaluate the mechanical impact of different direct restorations in terms of fracture resistance, and subsequent fracture pattern, in occlusal high C-factor cavities. Furthermore, the adaptation of different direct restorations in the form of gap formation was also evaluated. Seventy-two intact mandibular molars were collected and randomly distributed into three groups ( = 24).

Eighty upper premolars were randomly divided into four groups ( = 20/group). Standardized NCCL cavity preparations were performed on the buccal surface of the teeth and then restored with four different materials.

However, literature on the periodontal status of smokers with DM is scarce, and the studies conducted to date did not use healthy controls or non-smokers with DM as controls. Consequently, the individual effects of smoking and DM on PD are difficult to untangle and estimate.

Previous research suggests that systemic inflammatory conditions and cigarette smoking may act in synergy, and their co-occurrence leads to a much higher risk of developing severe stage PD than what the combination of their individual risks would suggest. We originally sought to test this in the case of RA, but it turned out that the majority of our patients were former smokers, who smoked for prolonged periods in the past.

Hormonal changes during pregnancy belong to the systemic aggravating factors. The aim of the present study was to assess pregnant women's oral hygiene knowledge and habits, and if these have a relationship with age, residence, educational level and profession/occupation.
