Efficiency of Empirically Administered Antibiotics in Patients with Cervical Infections of Odontogenic Origin

BACKGROUND AND AIMS

Odontogenic infections are among the main types of disorders located in the cephalic extremity. The aim of this study was to determine the efficiency of empirically administered antibiotics on the bacterial strains identified at the infection sites.

PATIENTS AND METHOD

The study included 10 randomly selected patients with odontogenic cervical soft tissue infections, who received antibiotic treatment prescribed by the family doctor or the dentist. The bacterial flora involved in the development of the septic process, the type of antibiotic administered to the patient and the sensitivity of the identified bacterial flora to the administered antibiotic were determined.

RESULTS

In the 10 selected patients, 14 bacterial strains were detected; 7 patients had a single bacterial strain, and 3 patients had two or three types of bacteria. Of the administered antibiotics, amoxicillin was the most widely used (33.3% of the cases), followed by amoxicillin with beta-lactamase inhibitors (25% of the cases). In half of the patients, there was no sensitivity of the bacteria detected in the septic focus to the empirically administered antibiotic, and in 10% of the cases, partial sensitivity was evidenced.

CONCLUSIONS

Empirical administration of antibiotics without the association of surgery did not prove to be effective in the treatment of cervical infections of odontogenic origin.

Subantral Augmentation with a 1/1 Alloplastic and Autologous Material Mixture. Histological Characteristics and Dimensional Stability of the Newly Formed Bone

Background and aim.

The maxillary sinus augmentation procedure is the most frequent method used to prepare the posterior maxillary area, with bone deficit, for the placement of dental implants. For this purpose, several types of materials have been used as bone grafts, each of these materials having a number of advantages and disadvantages. The present study is aimed at evaluating the histological and volumetric properties of an alloplastic and autologous material mixture.

Patients and methods.

The study included 7 selected patients who underwent subantral bone augmentation with a 1/1 autologous and alloplastic material mixture. Subsequently, at the time of dental implant placement, biological samples were taken from the bone augmentation area and were histologically analyzed. The subantral bone resorption rate was also evaluated in parallel.

Results.

Histological examination evidenced the presence of residual amorphous material in the bone augmentation area. The mean bone resorption rate was 15.15%. The presence of a high bone resorption rate was correlated with the presence of a smaller residual amorphous material amount in the subantral bone augmentation area.

Conclusions.

The association of autologous and alloplastic material for subantral bone augmentation improves the characteristics of the two material types.
