RESUMEN
Orthodontic treatments aim to enhance teeth functionality and aesthetics through various methods like permanent, removable, and functional appliances. These interventions may involve teeth removal, surgical procedures for alignment, and even jaw position adjustments. The treatment typically starts with the placement of an orthodontic device, followed by periodic adjustments. One major concern for patients is the associated pain, directly linked to the applied force. Various devices influence pain intensity, with fixed devices being more painful. Pain peaks after certain adjustments, like placing separators, and is attributed to decreased blood flow due to brace-induced force. Pain is the primary reason some patients consider discontinuing treatment. Pain management involves both pharmacological and non-pharmacological approaches, including the promising but still under-researched low-level laser therapy (LLLT) and light emitting diodes (LEDs). Dietary changes also play a role during treatment due to pain. Proper nutrition and oral hygiene guidance are essential from orthodontists and general dentists.
RESUMEN
Orthodontic devices, including both fixed and removable devices, have the potential to impact dental anatomy, the space within the oral cavity, the displacement of the tongue, and the production of speech. The usage of fixed labial appliances may cause transient or persistent speech and phonetics changes, particularly affecting sibilant and stopped sounds. Lingual fixed appliances, while providing aesthetic advantages, can lead to difficulties in maintaining oral hygiene, pain in the tongue, and speech disturbances. Orthodontic retainers, used post-treatment, can also affect speech and phonetics by altering the oral cavity space and tongue position. Other appliances like removable appliances, palatal expanders, and prosthetic dental appliances may also disrupt speech production. Objective, semi-objective, and subjective assessments are utilized to evaluate speech disruptions induced by orthodontic devices. Patients considering orthodontic aligners should be informed about potential temporary limitations in speech production, which can be managed by removing the device when necessary. The adaptation to orthodontic treatment may vary based on individual characteristics. Orthodontists should consider these effects and communicate them to patients. This review article explores the effect of orthodontic treatment on speech and phonetics.
RESUMEN
When cartilage-like tissue is present in the synovial membrane of joints, it is known as synovial chondromatosis (SC). The main cause is believed to be the metaplasia of embryonal mesenchymal tissue in the synovial membrane. The metaplastic foci grow within the joint space and can detach from the synovial wall, forming free-floating bodies. While SC is more commonly associated with trauma in the temporomandibular joint (TMJ), the exact relationship between trauma and SC remains unclear. Improved diagnostic techniques, such as CT and MRI, have led to increased recognition of SC in the TMJ. Gender differences in the prevalence of TMJ SC have been observed, with women being more affected. Diagnosis involves imaging techniques like X-rays, CT scans, MRIs, and surgical removal of loose bodies is the preferred treatment. Arthroscopy is recommended for small, isolated loose bodies, while open surgery may be necessary for complete removal. Long-term follow-up is essential to monitor for recurrence. Histopathological findings reveal a mixture of cartilage and bone, with ossification and calcification present.
