Identification of Specific Panoramic High-Risk Signs in Impacted Third Molar Cases in Which Cone Beam Computed Tomography Changes the Treatment Decision.

Purpose: The aim of this study was to investigate the treatment decisions of oral-maxillofacial surgeons in the management of impacted lower third molars (M3s) according to panoramic radiography (PR) and cone beam computed tomography (CBCT) risk analysis.

Patients And Methods: Ten surgeons analyzed 40 deliberately selected M3 cases showing 1 or more panoramic high-risk signs: 1) darkening of the root, 2) interruption of the white line, 3) diversion of the inferior alveolar canal (IAC), 4) narrowing of the IAC, and 5) 2 or more signs occurring simultaneously (including darkening and/or interruption of the IAC). After evaluating the PR images, the observers analyzed the patients' CBCT images.

The influence of the chosen in vitro bone simulation model on intraosseous temperatures and drilling times.

There is no consensus about the most suitable in vitro simulating material investigating heat generation during bone preparation. The aim was to compare heat increases and drilling times of bone removals in different bone simulating materials and to compare them to fresh human cadaver bone. A cavity was drilled in the following samples: (1) bovine rib; (2) pig rib; (3) 20 PCF (lb/ft) polyurethane (PU) block with 3 mm (50 PCF) cortical layer; (4) 20PCF PU without cortical; (5) 30 PCF PU with 2 mm (40 PCF) cortical; (6) 30 PCF PU with 1 mm (40 PCF) cortical; (7) 30PCF PU without cortical; (8) poly-methyl-methacrylate (PMMA); (9) fresh human cadaver rib.

Tooth sectioning for coronectomy: how to perform?

Objectives: The aim of this study was to determine the increase in heat production, preparation time, and cutting surface quality of conventional, high-speed rotating instruments and piezoelectric preparation for coronectomy procedures.

Materials And Methods: One hundred intact extracted molars were sectioned horizontally, sub-totally, 1 mm under the cemento-enamel line with five methods: (1) tungsten carbide torpedo (TcT), (2) round (TcR) drills using a conventional speed surgical straight handpiece (< 40,000 min), (3) tungsten carbide fissure (TcF), (4) diamond torpedo (DT) drills using a surgical high-speed, contra-angle handpiece (~ 120,000 min), or (5) a saw-like piezoelectric tip (PT). Temperatures, preparation times, and cutting surface irregularities were registered and the differences were analyzed with ANOVA, Tukey's HSD post hoc test (temperature, time) and with chi-square test (irregular surface).

Intracanal temperature changes during bone preparations close to and penetrating the inferior alveolar canal: Drills versus piezosurgery.

Purpose: The aim of this in vitro study was to investigate temperature increases in the inferior alveolar canal (IAC), when different bone preparation methods approximate and penetrate the IAC.

Materials And Methods: In pig mandible, buccal bone removals were performed until the neurovascular bundle became visible. Temperatures were registered with thermocouple probes and with infrared thermometer.

Effect of pre-drilling on intraosseous temperature during self-drilling mini-implant placement in a porcine mandible model.

This in vitro study investigated intraos seous heat production during insertion, with and without pre-drilling, of a self-drilling orthodontic mini-implant. To measure temperature changes and drilling times in pig ribs, a special testing apparatus was used to examine new and worn pre-drills at different speeds. Temperatures were measured during mini-implant placement with and without pre-drilling.

[Giant sialolithiasis: Diagnosis and management. Case reports].

Sialolithiasis is one of the most frequent form of calcifications in the maxillofacial area. 0.45% of the population is affected by symptoms caused by salivary calculi, though the estimated frequency including asymptomatic form may exceed 1% in adult population.

[Dental and oral surgical treatment of medication-induced bleeding patients: Audit of the national guideline in Hungary].

Introduction: In 2015 a new Hungarian guideline was published regarding dental treatment and management of anticoagulated patients in agreement of the Hungarian Association of Oral and Maxillofacial Surgeons and the Dental Implantology Association of Hungarian Dentists.

Aim: The aim of the authors was to evaluate the efficiency and safety of local hemostatic measures recommended by the guideline in anticoagulated patients.

Method: In these patients, postoperative bleeding episodes were examined after dental and oral surgical treatments, retrospectively.

[Sunitinib and zoledronic acid induced osteonecrosis of the jaw].

The tendency for bisphosphonate and non-bisphosphonate (eg.: antiresorptive or anti-angiogenesis drugs) induced osteonecrosis is increasing. Treatment of these patients is a challenge both for dentists and for oral and maxillofacial surgeons.

[Dental and oral surgical treatment of a B haemophilic patient with high inhibitor level. Case report].

More than 1000 hemophilic male patients are registered in Hungary, from which only a trace number suffers from factor IX inhibitory hemophilia. For correct dental and oral surgical treatment of these patients mandatory cooperation is required among medical specialties, exerting multi-staged haemostatic principles. Authors represent in this case report the dental and oral surgical treatment of a B hemophilic patient with high inhibitor level and describe possible local haemostatic measures.

[The specific panoramic radiographic signs and their relation with inferior alveolar nerve injuries after mandibular third molar surgery].

The aim of the authors was to describe the classic specific panoramic signs (indicating a close spatial relationship between dental canal and third molar's root) on panoramic radiographic images and determine their role in the risk assessment, predicting inferior alveolar nerve (IAN) paresthesia after lower third molar removal. The authors represented an informative case, where the IAN was visible during the surgery. The exact knowledge of classic panoramic radiographic signs should help the determination of "high risk" cases predicting IAN paresthesia after mandibular third molar removal.
