Do anti-inflammatory drugs worsen odontogenic cervico-facial cellulitis?

OBJECTIVE: The aim of this prospective study was to determine the influence of anti-inflammatory drugs on the severity of odontogenic cellulitis in patients admitted to our hospital emergency unit. STUDY DESIGN: The study was made from April 30 to October 31 2006. The clinical and pharmacological data was prospectively collected at admission, during hospitalization, and during systematic follow-up. We first studied the whole population and then compared the 2 groups: patients having received anti-inflammatory drugs before admission or not. RESULTS: Two hundred and sixty-seven patients were included. The only severity criterion significantly different between the 2 groups was spreading of cervical lymphangitis (P=0.028). None of the 4 studied parameters was identified as a risk factor for spreading of cervical lymphangitis in multivariate analysis: anti-inflammatory use (OR=5.99, 95%CI [0.71-50.88]), alcohol abuse (OR=4.00, 95%CI [0.66-24.12]), dental hygiene (OR=1.53, 95%CI [0.36-6.56]), and tobacco use (OR=0.27, 95%CI [0.57-1.28]). DISCUSSION: The use of anti-inflammatory drugs during the initial phase of an odontogenic infection was not related to the severity of infection.

[Bone substitutes: Classification and concerns]. / Les biomatériaux de substitution osseuse : classification et intérêt.

Autograft is considered as the "gold standard" for bone reconstruction. It provides osteoinductive factors, osteogenic cells, and appropriate osteoconductive scaffold. Donor site morbidity is the main limitation of autograft. Donor disease transmission limits the use of allograft. Synthetic bone substitutes still lack osteoinductive or osteogenic properties. Composite bone substitutes combining synthetic scaffold and biochemical substances initiating proliferation and cell differentiation, and possibly osteogenesis. Bone substitutes and grafts intended for clinical use are listed.

[Lateral repositioning of the inferior alveolar nerve before dental implant surgery: a simplified technique]. / Latéralisation du nerf alvéolaire inférieur à visée préimplantaire : une technique simplifiée.

External cortical bone osteotomy of the mandibular corpus allows an easy lateral repositioning of the alveolar nerve before dental implant surgery. This easy and reliable procedure is based on anatomical data. It minimises nerve lesion. It is indicated for patients presenting with an important posterior bone resorption for whom bone grafting is impossible.
