RESUMO
OBJECTIVES: Evidence on possible associations between facial morphology, attachment loss and gingival recession is lacking. We analysed whether the facial type, which can be described by the ratio of facial width and length (facial index), is related to periodontal loss of attachment, hypothesizing that a broad face might be associated with less gingival recession (GR) and less clinical attachment loss (CAL) than a long face. MATERIALS AND METHODS: Data from the 11-year follow-up of the population-based Study of Health in Pomerania were used. Periodontal loss of attachment was assessed by GR and CAL. Linear regression models, adjusted for age and gender, were used to assess associations between specific landmark based distances extracted from magnetic resonance imaging head scans and clinically assessed GR or CAL (N = 556). RESULTS: Analysing all teeth, a higher maximum cranial width was associated with a lower mean GR (B = -0.016, 95% CI: -0.030; -0.003, p = 0.02) and a lower mean CAL (B = -0.023, 95% CI: -0.040; -0.005, p = 0.01). Moreover, a long narrow face was significantly associated with increased mean GR and CAL (facial index, P for trend = 0.02 and p = 0.01, respectively). Observed associations were more pronounced for incisors and canines than for premolars and molars. CONCLUSION: This study revealed craniofacial morphology, specifically the cranial width and the facial index, as a putative risk factor for periodontal loss of attachment.

This report describes the role of severe pain in failure of dental implants. A 27-year-old woman presented to the clinic to replace the missing mandibular right first molar and second premolar. A panoramic radiograph was taken, and a clinical examination was done. A decision was made to extract the mandibular right second molar, which had failing endodontics, and two dental implants were placed. Two days later, the patient reported severe pain in that area. Microscopic examination of the surgical specimen revealed longitudinal section of peripheral nerve in the implant site.

After removal of a dental implant or extraction of a tooth in the upper jaw, the closure of an oroantral fistula (OAF) or oroantral communication (OAC) can be a difficult problem confronting the dentist and surgeon working in the oral and maxillofacial region. Oroantral communication (OAC) acts as a pathological pathway for bacteria and can cause infection of the antrum, which further obstructs the healing process as it is an unnatural communication between the oral cavity and the maxillary sinus. There are different ways to perform the surgical closure of the OAC. The decision-making in closure of oroantral communication and fistula is influenced by many factors. Consequently, it requires a combination of knowledge, experience, and information gathering. Previous narrative research has focused on assessments and comparisons of various surgical techniques for the closure of OAC/OAF. Thus, the decision-making process has not yet been described comprehensively.The present study aims to illustrate all the factors that have to be considered in the management of OACs and OAFs that determine optimal treatment.
RESUMO
Gardner syndrome is an autosomal dominant disease. It is characterized by a combination of familial adenomatous polyposis (FAP) of the intestine with extraintestinal changes as multiple osteomas and fibromas. Odontogenic Myxoma is a benign, aggressive intraosseous neoplasm. We report a rare case of a 14-year-old male patient with Gardner's syndrome and odontogenic myxoma, which involved the entire left half of the mandible, resulting in a gross facial deformity, within a span of one year.

An oroantral fistula (OAF) is a pathological abnormal communication between the oral cavity and the maxillary sinus which may arise as a result of failure of primary healing of an OAF, dental infections, osteomyelitis, radiation therapy, trauma, or iatrogenic complications. With the presence of a fistula, the maxillary sinus is permanently open. Microbial flora passes from the oral cavity into the maxillary sinus, and the inflammation of the sinus occurs with all potential consequences. In literature, various techniques have been proposed for closure of OAFs. Due to the heterogeneity of the data and techniques found, we opted for a narrative review to highlight the variety of techniques discussed in the literature. Techniques of particular interest include the bone sandwich with resorbable guided tissue regeneration (GTR) membrane and platelet-rich fibrin (PRF) used alone as both a clot and a membrane. The great advantage of these techniques is that no donor site surgery is necessary, making the outcome valuable in terms of time savings, cost and, more importantly, less discomfort to the patient. Additionally, both bony and soft tissue closure is performed for OAF, in contrast to flaps, which are typically used for procedures in the sinus area. The reconstructed bony tissue regenerated from these techniques will also be appropriate for endosseous dental implantation.
RESUMO
Hemifacial hyperplasia is a rare developmental anomaly characterized by marked unilateral facial tissues. It involves orofacial soft tissues, bones of the face, and teeth. The cause remains ambiguous although several predisposing factors have been reported. A case report of a 32-year-old girl with unilateral hemifacial enlargement, pain in temporomandibular joint, and limited mouth opening associated is presented to highlight the clinical and imaging findings and to discuss the differential diagnosis.
