The expression of endogenous hydrogen sulfide signal during distraction osteogenesis in a rabbit model
The hydrogen sulfide (H2S) signal system plays an important role in bone metabolism. However, the role of endogenous H2S during distraction osteogenesis (DO) remains unclear. Sixty-two male New Zealand White rabbits were subjected to right mandibular DO. Before distraction, the animals were divided randomly into two groups: group A, 0.5mm twice/day for 10 days; group B, 1.25mm twice/day for 4 days. Plasma and distraction gap tissue were harvested to determine the H2S signal. The osteogenesis effect was also evaluated. (Source: International Journal of Oral and Maxillofacial Surgery)

Two-stage reconstruction of the severely deficient alveolar ridge: bone graft followed by alveolar distraction osteogenesis
Distraction osteogenesis for the augmentation of severe alveolar bone deficiency has gained popularity during the past two decades. In cases where the vertical bone height is not sufficient to create a stable transport segment, performing alveolar distraction osteogenesis (ADO) is not possible. In these severe cases, a two-stage treatment protocol is suggested: onlay bone grafting followed by ADO. An iliac crest onlay bone graft followed by ADO was performed in 13 patients: seven in the mandible and six in the maxilla. (Source: International Journal of Oral and Maxillofacial Surgery)

Previously successful dental implants can fail when patients commence anti-resorptive therapy —a case series
This article reports a type of localized osteonecrosis that can occur in patients who have had successful osseointegrated implants for many years and then commence anti-resorptive therapy. Eleven female patients were identified who had successful implant insertion, but who were placed on anti-resorptive therapy (bisphosphonates or denosumab) several years later and developed osteonecrosis around the implants. In each case, the osteonecrosis occurred only around the implants and not around the patient ’s remaining teeth. (Source: International Journal of Oral and Maxillofacial Surgery)

The horizontal inclination angle is associated with the risk of inferior alveolar nerve injury during the extraction of mandibular third molars
The extraction of mandibular third molars can lead to injury to the inferior alveolar nerve. Hence, it is important to assess the proximity of the root to the inferior alveolar canal before extraction. The classification system of Pell and Gregory and the Winter classification are commonly used to evaluate the positional relationship of the third molar based on radiographs. This retrospective study involving 105 mandibular third molars was performed to assess whether these systems reflect the proximity of the root to the canal (based on computed tomography images), and to identify risk factors for nerve injury.

Long-term evaluation of single-puncture temporomandibular joint arthrocentesis in patients with unilateral temporomandibular disorders
The purpose of this study was to evaluate the long-term effects of the single-puncture arthrocentesis (SPA) technique. Forty-two patients with unilateral temporomandibular joint disorders (TMDs) were treated by SPA. Thirty-eight of these patients completed 1 –24 months of follow-up (short-term group) and 21 completed 11 months or longer of follow-up (long-term group). The two groups were evaluated statistically for pain (visual analogue scale), maximum mouth opening, lateral excursion, and protrusion.

Management of the condyle following the resection of tumours of the mandible
The aim of this study was to assess the management of the condyle during the restoration of mandibular defects following tumour resection. A total of 41 patients who underwent simultaneous tumour resection and reconstruction with vascularized iliac myocutaneous flaps for mandibular defects, from September 2010 to October 2014, were included. These patients were divided into three groups: group 1, condyle preserved; group 2, condyle sacrificed; group 3, condyle frozen. Patients were followed up at 1, 3, 6, and 12 months for the evaluation of appearance, occlusion, and speech. (Source: International Journal of Oral and Maxillofacial Surgery)

Assessment of obstructive sleep apnoea treatment success or failure after maxillomandibular advancement
Maxillomandibular advancement (MMA) is an alternative therapeutic option that is highly effective for treating obstructive sleep apnoea (OSA). MMA provides a solution for OSA patients that have difficulty accepting lifelong treatments with continuous positive airway pressure or mandibular advancement devices. The goal of this study was to investigate the different characteristics that determine OSA treatment success/failure after MMA. The apnoea –hypopnoea index (AHI) was used to determine the success or failure of OSA treatment after MMA. (Source: International Journal of Oral and Maxillofacial Surgery)
