Transient cutaneous hypomelanosis after cryoanesthesia.

A superficial skin abscess in a young black female patient was incised after cryoanesthesia with tetrafluoroethane spray. A hypopigmented area was found at the first follow-up visit in the treated skin area; complete repigmentation occurred during the next 4 months. There are no other similar reported cases in the literature.

Are there difficulty variables in maxillary third molar surgery? A prospective observational cohort study.

Background: The main aim of the present study was to assess which factors were related to surgical difficulty in maxillary third molar extraction. Intra- and postoperative complications were also evaluated.

Methods: A prospective observational cohort study was performed on out-patients who underwent impacted maxillary third molar extraction.

Surgical uprighting and repositioning of unerupted molars: Features and findings of a retrospective sample.

Background: Surgical uprighting and repositioning have been proposed to obtain a correct alignment of unerupted permanent molars. A retrospective clinical study was performed to verify the effectiveness of these techniques.

Material And Methods: In order for a case to be included in the study, adequate clinical documentation was required, including radiographic imaging before and after therapy.

A Prospective Observational Study on the Variables Affecting the Risk of Inferior Alveolar Nerve Damage During Lower Third Molar Surgery With Nerve/Root Proximity.

Purpose: The present study aimed to evaluate which factors were statistically associated with a greater probability of inferior alveolar nerve (IAN) damage during lower third molar surgery.

Methods: A prospective observational study was performed at the Oral Surgery Unit of the Umberto I Hospital on 92 patients who underwent surgical extraction of a lower third molar that was radiographically overlapped with the mandibular canal. All surgeries were performed by the same expert surgeon.

The VISTA Approach in Canine Disimpaction.

Canine disimpaction is always a challenging orthodontic treatment overall, even when the impacted permanent canine is in a high position, especially when in tight relation with the upper incisors' roots. Conventional treatment methods are usually not capable of performing the correct force direction, consisting of the contemporary movement in the distal and vestibular directions of the canine crown, often provoking, as side effects, the presence of decubitus on the mucous of the lips and cheeks or a poor final appearance of the periodontal support of the disimpacted canine. Among the different approaches, the vertical incision subperiosteal tunnel access (VISTA) technique shows good performance with regard to the direction of the forces and the canine's periodontal conditions when erupted; it is usually realized through an elastic chain connected to a temporary anchorage device (TAD) in the posterior area.

Acanthomatous Ameloblastoma: An Early Stage Case Report with Difficult Management.

A case of a mandibular acanthomatous ameloblastoma, with an admixed little component of follicular type, is reported. The epidemiological features of the present case agree with those reported in the international literature. Clinico-radiographic differential diagnostic difficulties existed with several other noncystic osteolytic lesions of the mandible.

What is the Risk of Developing Medication-Related Osteonecrosis in Patients With Extraction Sockets Left to Heal by Secondary Intention? A Retrospective Case Series Study.

Purpose: Tooth and root extractions represent trigger factors for medication-related osteonecrosis of the jaw (MRONJ). The best healing modality for postextraction sockets is still debated. The aim of the study was to estimate the incidence of MRONJ after extractions whose sockets were left to heal by secondary intention.

Is telephone follow-up useful in preventing post-extraction bleeding in patients on antithrombotic treatment?

Background: The aim of the study was to investigate the usefulness of telephone follow-up in preventing post-extraction bleeding and improving wound healing in patients on chronic antithrombotic treatment.

Material And Methods: A prospective randomized clinical trial was carried out on 256 patients (test group = 128; control group = 128). The exact two-tailed Fisher test and the two-tailed non-parametric Mann-Whitney test were used for statistical analysis.

Tooth extraction without discontinuation of oral antithrombotic treatment: A prospective study.

Objective: To identify which variable, among those related to surgeries, to patients, or to antithrombotic treatments, could be considered as a bleeding indicator, and to analyze effectiveness of the local hemostatic protocols used, incidence of bleeding and healing index, depending on the number of extracted teeth, and patient antithrombotic treatment.

Methods: Patients who underwent tooth extractions without interruption or reduction of antithrombotic treatment were prospectively followed. The exact two-tailed Fisher test was used to investigate the relationship between presence/absence of bleeding and type of hemostatic material.
