Objectives: Mental artery flow decreases with age and may have an aetiological role in alveolar ridge atrophy. The aim of this study was to identify factors associated with alterations of mental artery flow, assessed by ultrasonography. Methods: This case-control study was conducted on elderly patients (aged above 60 years) at the beginning of dental treatment. Intraoral B-mode Doppler ultrasonography was used to assess mental artery flow. The cases were defined as patients with a weak/absent ultrasound signal, whereas the controls presented a strong ultrasound signal. Demographics and radiographic findings (low bone mineral density on dual-energy X-ray absorptiometry and mandibular cortical index on panoramic radiographs) were analysed as risk factors for weak/ absent ultrasound signal and were calculated as adjusted odds ratios (AORs) with 95% confidence intervals (CIs) using conditional logistic regression. In addition, the Student's t-test was used to compare the mean alveolar bone height of the analysed groups. A p-value ,0.05 was considered statistically significant. Results: A total of 30 ultrasound examinations (12 cases and 18 controls) were analysed. A weak/absent mental artery pulse strength was significantly associated with edentulism (AOR 5 3.67; 95% CI 5 0.86-15.63; p 5 0.046). In addition, there was a significant difference in alveolar bone height between edentulous cases and controls (p 5 0.036). Conclusions: Within the limitations of this study, the present results indicate that edentulism is associated with diminished mental artery flow, which, in turn, affects alveolar bone height.

“…The sublingual artery may enter the lingual cortex of the anterior mandible. The perforating submental artery was present in the anterior mandible, whereas the sublingual artery was small or was missing in the submental area of the mandible 3 . Mechanical injury to the local arterial plexus may potentially lead to dangerous hemorrhage.…”

“…In addition, the sublingual artery releases several alveolar branches for complementary blood supply to the lingual anterior cortical bone of the mandible 3,4,10 . The submental artery is the largest cervical branch of the facial artery, coursing anteriorly on the mylohyoid muscle and branching to anastomose with the sublingual artery and with the mylohyoid artery deep into the mylohyoid muscle.…”

“…The submental artery is the largest cervical branch of the facial artery, coursing anteriorly on the mylohyoid muscle and branching to anastomose with the sublingual artery and with the mylohyoid artery deep into the mylohyoid muscle. At the anterior mandible, it divides into deep and superficial branches, anastomosing with the inferior labial and mental arteries 3,4 . In human cadaver studies, the sublingual artery is located in the mandibular anterior region, and the submental artery perforates the mylohyoid muscle into the anterior mandible 4 .…”

“…The anterior mouth floor (AMF) is rich in blood vessels, including the sublingual artery and submental artery 3,4 . Thus, when a fixture is placed by penetrating the lingual cortex for implantation in the area of the mandibular anterior teeth, severe hemorrhage may occur if the surrounding soft tissue and blood vessels of the AMF area are damaged.…”

Life-threatening airway obstruction after flapless implant placement in the anterior mandible

(J Korean Assoc Oral Maxillofac Surg 2012;38:310-3) This paper reports a patient who had an airway obstruction caused by a hemorrhage of the mouth floor that occurred after she underwent flapless implantation in the region of the mandibular anterior teeth. The hemorrhage may have been caused by iatrogenic malpositioned fixture and patient's hypertension. The lingual periosteum was not dissected during the flapless procedure. Therefore, when hemorrhage occurred, the blood did not drain easily into the oral cavity but instead drained into the deep neck region, which might have been the cause of the airway obstruction. Key words: Airway obstruction, Dental implants[paper submitted 2011. 11. 24 / accepted 2012. 2. 20] II. Case ReportA 56-year-old female patient came to the emergency room (ER) with chief complaint of dyspnea due to swollen tongue and neck. The medical history was remarkable for hypertension. The dental history showed that, earlier on the day of her visit to the ER, the patient had undergone at a local dental clinic extraction of both lower central incisors followed immediately by flapless implantation. According to the patient's history of chief complaint, there was continuous oozing around the surgical site after the implant was installed at around 3 pm that day. Her dentist could not give her an acceptable explanation for her condition, so the patient visited the ER at 10:30 pm with the swelling aggregated around her neck area.The patient said her symptoms of edema and dyspnea had begun on the AMF after the implantation. Clinical examination in the ER showed severe swelling of the AMF and tongue, accompanied by ecchymosis and orthopnea. The patient's respiration rate was 20 times per minute, and routine lab results including hemoglobin, T-CO 2 , and PT and aPTT were all within normal limits. Her SpO 2 was over 98%, and systolic and diastolic blood pressure (BP) in sitting position were 160 mmHg and 100 mmHg, respectively. Note, however, that the patient's vital signs worsened in the SemiFowler's and supine positions. A computed tomography (CT) of the neck could not be performed immediately after the
