Neurosensory recovery of inferior alveolar nerve gap reconstruction: a systematic review.

Numerous procedures can potentially injure the inferior alveolar nerve during oral and maxillofacial surgery, eventually causing loss or alteration of local sensitivity. When its total rupture occurs, a conduit, such as an autogenous graft, can be used to join it. Due to the morbidity resulting from this technique, alternative forms of sensorineural repair have been investigated. This systematic review includes an electronic search of PubMed, Embase, LILACS, and Web of Science databases, in addition to a grey literature and manual search. Article selection was performed by two independent researchers following a predetermined inclusion criterion: human studies evaluating the regression of sensorineural disorders after any form of grafting (autogenous, allogeneic, and synthetic). Of the 789 studies, 648 were analysed. Only 11 articles met the eligibility criteria. After analysing the results, it was noted that regaining normal sensitivity was uncommon, but the majority of reconstructed nerves recovered their protective abilities. Allografts showed success rates similar to autogenous grafts, making them a viable alternative. However, clinical trials are still needed to provide solid evidence. Prognosis for sensory recovery was impacted by grafting time and patient age.

The Use of Antibiotics in Odontogenic Infections: What Is the Best Choice? A Systematic Review.

PURPOSE: Odontogenic infections are a common problem in dentistry, and their treatment often requires the use of antibiotics besides the removal of the source of infection, which frequently makes it more difficult for clinicians to make a decision regarding the choice of antibiotic. This study aimed to answer the following questions through the Patient, Intervention, Comparison, Outcome (PICO) format: When should antibiotics be used in dental infections (DIs)? Which are the most effective drugs? How long should antibiotics be administered? MATERIALS AND METHODS: This was a systematic review using the PubMed, Scopus, and Cochrane databases without restriction as to the period researched. The variables analyzed in each article were the number of odontogenic infections in each study, type of study, surgical intervention performed, antibiotics administered, statistical differences between groups studied, and patients' evolution after treatment. RESULTS: The search included 1,109 articles. After the full reading of 46 articles, 16 were included in the final review and 30 were excluded. A sample of 2,197 DI cases was obtained, in which 15 different antibiotics were used, with a 98.2% overall cure rate. CONCLUSIONS: The studies showed that antibiotics were prescribed only in situations of regional and/or systemic body manifestations. In the case of DIs, once drainage has been performed and/or the cause of infection has been removed, all antibiotics tested are equally effective with respect to clinical cure, and the choice of antibiotics is not as successful as the local intervention treatment procedure. When the real need for antibiotic therapy is detected, antibiotics should be used for the shortest time possible until the patient's clinical cure is achieved.

Reestablishing the Function and Esthetics in Traumatized Permanent Teeth with Large Apical Lesion.

Dental trauma is a challenge for dental integrity and can lead to pulp necrosis. The clinical case reports the diagnosis of a maxillary right central incisor traumatized and its multidisciplinary treatment. Calcium hydroxide material was used to perform the processing apexification. An apical surgery was carried out to remove the apical periodontitis and to return the aesthetics to the patient; internal and external tooth whitening in maxillary right central incisor was performed. We conclude that surgery associated with the root filling in the central incisor led to a successful completion. Moreover, it is of utmost importance to demonstrate the interaction between the various areas of dentistry.
