Introduction: Three-dimensional finite elemental analysis (FEA) is a contemporary research instrument for the numeric simulation of a real physical system's mechanical process. FEA can be used as a very effective tool to analyze and compare various aspects of rapid palatal expanders and to determine the stress distribution in maxillofacial bones and displacement and the biomechanical effects it has on the circummaxillary sutures. This study evaluates the effects of different modes of rapid palatal expansion on maxillary protraction as a treatment modality in skeletal Class III malocclusion by determining the stress and displacement along the circummaxillary sutures using the FEA.

- The study compares two dental materials—self-etch adhesive (SEA) and self-adhesive flowable composite (SAF)—for their tensile bond strength (TBS) and microleakage (LK) in primary molars subjected to artificial aging.
- 120 extracted primary molars were tested, with different subgroups experiencing mechanical loading and thermal aging to assess their performance under varying conditions.
- Results showed that SAF had better TBS than SEA, and mechanical loading negatively impacted both TBS and LK, indicating that SAF is more effective for restoring primary teeth.
Aim: The objectives are to compare the extent and to find whether it is arch dimension or tooth size that contributes to a greater extent to malocclusions such as dental crowding and proclination.
Materials And Methods: A total of 90 pretreatment models were selected and divided into three groups, namely uncrowded (Group-A), crowded (Group B), and proclination (Group-C). Measurements obtained were: (1) The largest mesiodistal width of each tooth on each arch (except the second and third molars), (2) Buccal inter-canine and inter-molar widths, (3) Lingual inter-canine and inter-molar widths, (4) Arch perimeters, and (5) Arch length.
