BACKGROUND There is strong evidence that malocclusion and body posture are interdependent. The relationship between improvement of nasopharyngeal airway, correction of malocclusion by orthodontic treatment or orthognathic surgery, and changes in body posture were evaluated in several studies. The purpose of the present study was to analyze the effect of the orthodontic treatment with Twin-block appliance on body posture. MATERIAL AND METHODS The study group consisted of 23 children (mean age 12.45 (1.06) years)...

Temporomandibular joint ankylosis is a unique disease where fracture of the mandibular condyle or any other cause leading to ankylosis of the joint can lead to multiple problems if not detected and treated early. If affected in early years of life, it may cause facial dysmorphism, restricted mouth opening, and difficulty in eating, speech, and sleep. Early surgery and physiotherapy can restore the joint function to a great extent. Anesthetizing a pediatric patient with this disorder is a definite challenge which needs expertise in difficult airway management...

BACKGROUND: Limited mandibular condylar mobility plays an important role in difficult laryngoscopy. Indirect assessment methods, such as mouth opening, have been proven to be useful predictors of difficult laryngoscopy. Sonography is a new direct assessment method for the limited mandibular condylar mobility. However, whether this method could be used in predicting difficult laryngoscopy still remains unknown. This study aimed to observe its ability to predict difficult laryngoscopy. METHODS: Adult patients who were administered tracheal intubations for elective surgery under general anesthesia were enrolled in the study...

Transoral robotic surgery (TORS) is a fascinating new technique that has been proved to be a safe and feasible for selected oropharyngeal cancers. Furthermore, TORS offers several advantages in the treatment of locoregionally advanced cancers. Nevertheless, the careful selection of patients is the keypoint for a successful application of this therapeutic modality. However, the reconstruction of large oropharyngeal defects is challenging due to the restoration of velopharyngeal competency and swallowing. Moreover, the absence of mandibular splitting increases the difficulties faced by reconstructive surgeons...

Medication-related osteonecrosis of the jaws (MRONJ) is an adverse side effect of several drug therapies, including bisphosphonates (BPs). Osteonecrosis of the jaw specifically related to BP therapy is usually referred to using the acronym BRONJ. However, no consensus has yet been reached regarding the most appropriate management of BRONJ. The greatest success rates have been recorded with surgical removal of necrotic bone. In particular, erbium:yttrium-aluminum-garnet (Er:YAG) laser-assisted surgery has shown significantly better results than conventional surgical approaches...

Surgery-first approach (SFA) has been a paradigm shift in the field of orthognathic surgery. Majority of the published cases that have been managed by this approach are of skeletal class III. This communication describes a patient of 18-year-old male diagnosed with skeletal class II malocclusion due to mandibular retognathism. He was managed with SFA and was using skeletal anchorage system to prevent postsurgical relapse. Bilateral saggital split ramus osteotomy was carried out to achieve the mandibular advancement of 7 mm...

Mental nerve (MN) injury is the most common complications of genioplasty; to protect the MN and oral mucosa, the authors invent and validate the appropriate retractors for genioplasty, and which can avoid the skin and mucous membrane of the lower lip, chin, and the vestibular gingiva of the mandibular incisor from paresthesia or dysesthesia. The patent application for the appropriate retractors for genioplasty is already submitted (Patent No 201610164563.3, China). The retractors provide a better surgical visual field and improve the operation efficiency while reducing the risk of surgery...

Mandibular prognathism is usually treated with mandibular setback surgery. However, this approach reduces the pharyngeal airway space, and can aggravate obstructive phenomena in patients with obstructive sleep apnea (OSA). While maxillary expansion is known to lead to an increase in the pharyngeal airway volume (PAS), its effect on the PAS in mandibular setback surgery has not yet been reported. The authors report a surgical approach with maxillary expansion in 2 patients with mandibular prognathism that was accompanied by OSA: maxillary midsagittal expansion with minimum maxillary advancement and minor mandibular setback without mandibular anterior segmental osteotomy (ASO) or major mandibular setback with mandibular ASO...

Stromal cell-derived factor-1 (SDF-1) is a cytokine that is important in stem and progenitor cell recruitment in tissue repair after injury. Regenerative procedures using collagen membranes (CMs) are presently well established in periodontal and implant dentistry. The objective of this study is to test the subsequent effects of the released SDF-1 from a CM on bone regeneration compared to platelet-derived growth factor (PDGF) in vitro and in vivo. For in vitro studies, cell proliferation, alkaline phosphatase activity, and osteoblastic differentiation marker genes were assessed after MC3T3-E1 mouse preosteoblasts were cultured with CMs containing factors...

Any insult to the pulp during its development causes cessation of dentin formation and root growth. Pulpal status and degree of root development are the decisive factors in the treatment approach. Various treatment options have been tried like surgery with root-end sealing, calcium hydroxide-apexification, placement of apical plug and regenerative endodontic procedures to induce apexogenesis. An ideal scenario for a necrosed tooth with immature root would be continued root development coupled with regeneration of pulp tissue...
