Sensibility and taste alterations after impacted lower thirdmolar extractions. A prospective cohort study

Objectives: To determine the incidence, severity and duration of lingual tactile and gustatory function impairments after lower third molar removal.Study Design: Prospective cohort study with intra-subject measures of 16 patients undergoing lower third molar extractions. Sensibility and gustatory functions were evaluated in each subject preoperatively, one week and one month after the extraction, using Semmes-Weinstein monofilaments and 5 different concentrations of NaCl, respectively. Additionally, all patients filled a questionnaire to assess subjective perceptions.Results: Although patients did not perceive any sensibility impairments, a statistically significant decrease was detected when Semmes-Weinstein monofilaments. This alteration was present at one week after the surgical procedure and fully recovered one month after the extraction. There were no variations regarding the gustatory function. Conclusions: Lower third molar removal under local anesthesia may cause light lingual sensibility impairment. Most of these alterations remain undetected to patients. These lingual nerve injuries are present one week after the extraction and recover one month after surgery. The taste seems to remain unaffected after these procedures (AU)

Fragile X-syndrome: literature review and report of two cases.

Fragile X-syndrome is caused by a mutation in chromosome X. It is one of the most frequent causes of learning disability. The most frequent manifestations of fragile X-syndrome are learning disability, different orofacial morphological alterations and an increase in testicle size. The disease is associated with cardiac malformations, joint hyperextension and behavioural alterations. We present two male patients aged 17 and 10 years, treated in our Service due to severe gingivitis. Both showed the typical facial and dental characteristics of the syndrome. In addition, we detected the presence of root anomalies such as taurodontism and root bifurcation, which had not been associated with fragile X-syndrome in the literature. In some cases these root malformations have been associated with other sex-linked congenital syndromes, though in none of the studies published in the literature have they been related with fragile X-syndrome. This syndrome is relevant due to its high prevalence, the presentation of certain oral and facial characteristics that can facilitate the diagnosis, and the few cases published to date.

Accidental displacement of dental implants into the maxillary sinus: a report of nine cases.

PURPOSE: To report on the clinical, radiological, and anatomical features of patients suffering accidental displacement of dental implants into the maxillary sinus. MATERIALS AND METHODS: A retrospective observational study of nine cases of dental implant displacement into the maxillary sinus was made. Data concerning patients' features, diagnostic criteria, and treatment performed were collected. RESULTS: Mean patient age was 56.7 years, and men predominated (6 : 3). Implant displacement was diagnosed in all cases by clinical and radiological examination. In seven patients, the implant was surgically removed without complications. Only three patients reported sinus symptoms following displacement. CONCLUSIONS: The displacement of implants into the maxillary sinus is usually related with a poor surgical planning or inadequate surgical technique. Because of the anatomy and physiology of the posterior area of the maxilla, it is essential to ensure good primary stability in order to avoid this complication. If the implant migrates into the maxillary sinus, it should be removed in order to avoid sinus pathology.
