Background: Bite force is one of the important factors that determine the chewing efficiency of molars. This study aimed to investigate the relationship of the maximum bite force (MBF) to the 3-dimensional (3D) arrangement of the first mandibular molars in Angle's class I healthy adults using a digital protocol.
Material And Methods: Subjects were 33 adults (16 males and 17 females) aged 18-25, with Angle's class I occlusions and healthy dentitions. MBF was recorded by a digital occlusal force gauge (BFM 4th generation, Vietnam). 3D models were scanned using TRIOS 3 intra-oral scanner (3Shape, Denmark), and analyzed using Geomagic Design X software (Artec, Luxembourg). The digital measurement included two steps: reorientation and measuring. First, all the virtual upper models were reoriented into the same Oxyz coordinates using 3 landmarks: one at the incisive papilla and two at the intersection of the palatal sulci of the first permanent molars with the gingival margin. Next, 3D position of the first mandibular molars was measured using crown angulation (CA), crown inclination (CI), and depth of curve of Spee (DCOS). t-tests were conducted to compare the mean values between sides and gender. Pearson's correlation coefficient was performed to evaluate the statistical relationships.
Results: Mean MBF was 619.66±36.25 N; mean DCOS was 1.73±0.30 mm; mean CA and CI were 2.21±1.70° and -29.65±6.93°, respectively. Male adults showed greater MBF than females significantly. Correlation coefficient between MBF and CA was -0.60, and between MBF and CI was -0.43 significantly. MBF and DCOS were not related.
Conclusions: MBF was influenced by gender and the first mandibular molar CA and CI. Hence, it should be considered carefully when the treatment plan includes restoration or any change in the position of the first mandibular molars.

Adult Scissor Bite Case Treatment With Moving Teeth Through Maxillary Sinus.

Department of Orthodontics, College of Dentistry, Dankook University, Cheonan, South Korea.
Objective: This case report demonstrates the orthodontic treatment to correct a severe scissor bite and occlusal disharmony in a 26-year-old female patient, including the use of temporary anchorage devices (TADs) and fixed orthodontic appliances.
Clinical Considerations: Severe scissor bite is associated with vertical problems, such as molar extrusion. For orthodontic treatment, interradicular TADs were used to intrude the extruded molars, control the inclination of molars, correct dental midline, and improve dental relationships.
Association and relevant factors between objective masticatory performance and subjective masticatory ability among community-dwelling older adults.

Department of Oral Hygiene, College of Dental Medicine, Kaohsiung Medical University, Kaohsiung, Taiwan.
Background/purpose: Dentists often focus on masticatory performance (MP) rather than masticatory ability (MA) and treatment expectations when evaluating older adults. This study aimed to determine if MA aligns with MP and to explore influencing factors.
Materials And Methods: This cross-sectional study utilized a multi-stage stratified cluster sampling, including one thousand community-dwelling adults aged 60 and older.

The aim of this study was to compare the effectiveness of different types of low level laser treatment (LLLT) in reducing pain levels, changing oxygen saturation and bite force in patients with myofacial pain syndrome (MPS). 45 patients were randomly assigned to three groups: Group 1 (GRR laser, n = 15) received LLLT with Gallium-Aluminium-Arsenide (GaAlAs) diode laser with a wavelength of 904 nm and red laser with a wavelength of 650 nm over masseter muscle region. Group 2 (Nd: YAG laser, n = 15) were treated with Neodymium-doped Yttrium Aluminium Garnet laser with a wavelength of 1064 nm and the same protocol with Nd: YAG laser was performed in the Group 3 (placebo, n = 15) using sham device.
