“…Demarco et al 39 add that dentists may be considered a key factor in the success of restorations because they are responsible for all restorative procedures and other clinical decisions that could influence durability, and that dentists favoured repair of defective restorations when they had placed the original restoration, whereas the same restoration was more likely to be replaced when it was evaluated by a different dentist!…”

Longevity of Indirect and Direct Restorations in Anterior Teeth

It is the aim of this paper to present data on the survival of direct and indirect restorations in anterior teeth. Two sources of information are used: previously-published analysis of data from 1990 to 2006 from a 13 million restoration dataset from England and Wales; and evidence from published literature from 2011 to the time of writing (March 2022). The findings suggest that: (1) directly-placed resin composite materials may provide satisfactory survival of restorations in anterior teeth; (2) crowns provide better survival to re-intervention: however, crowning an incisor or canine tooth, as opposed to placement of a direct restoration, will lead to an earlier time to extraction of the restored tooth; (3) veneers perform more favourably than other restorations in terms of time to extraction of the restored tooth, but may have a less favourable time to re-intervention than crowns; (4) lithium disilicate crowns may be considered to perform satisfactorily with regard to time to re-intervention when placed in anterior teeth, but less satisfactorily in posterior teeth; and (5) operator factors influence survival of restorations.

“…According to a recent FDI policy statement, such materials should exhibit a clear mechanism of biological and/or chemical effect without significant adverse biological side effects, in addition to restoring form and function of lost tooth substance. 3 Bioactivity is expected to mitigate secondary caries as one of the main causes of restorative failure, 4,5 but also to aid in pulpal defense mechanisms. 6 Synthetic calcium orthophosphates (CaP) with apatite structure, such as hydroxyapatite (HAP) and tricalcium-phosphates (TCP), are chemically and structurally similar to the inorganic part of human bones and teeth.…”

This study aimed to (1) comparatively analyze properties of Sr‐ and Mg‐substituted hydroxyapatite (HAP)‐based dental inserts; (2) evaluate insert bonding to restorative materials, and (3) evaluate the effect of doped HAP inserts on fracture resistance (FR) of human molars with large occlusal restorations. By ion‐doping with Sr or Mg, 3 insert types were obtained and characterized using XRD, SEM, Vickers hardness and fracture toughness. Shear bond strength (SBS) was determined between acid etched or unetched inserts and following materials: Maxcem cement (Kerr); Filtek Z250 (3M) bonded with Single Bond Universal (SBU; 3M) or Clearfil Universal (Cf; Kuraray). Modified Class I cavities were prepared in 16 intact molars and restored using insert + composite or composite only (control) (n = 8/group). FR of restored molars was determined by static load until fracture upon thermal cycling. Fracture toughness was similar between Sr/Mg‐doped inserts (0.94–1.04 MPam−1/2 p = .429). Mg‐doped inserts showed greater hardness (range 4.78–5.15 GPa) than Sr6 inserts (3.74 ± 0.31 GPa; p < .05). SBS for SBU and Cf adhesives (range 7.19–15.93 MPa) was higher than for Maxcem (range 3.07–5.95 MPa) (p < .05). There was no significant difference in FR between molars restored with insert‐containing and control restorations (3.00 ± 0.30 kN and 3.22 ± 0.42 kN, respectively; p > .05). HAP‐based inserts doped with Mg/Sr had different composition and mechanical properties. Adhesive bonding to inserts resulted in greater bond strength than cementation, which may be improved by insert acid‐etching. Ion‐doped HAP inserts did not affect FR of restored molars. In conclusion, HAP‐based dental inserts may potentially replace dentin in large cavities, without affecting fracture resistance of restored teeth.
