The aim of this review was to assess efficacy and acceptance of aesthetic zirconia crowns (ZCs) compared to the traditionally employed stainless steel crowns (SSCs) for primary teeth restoration. A comprehensive literature search was completed for the relevant keywords in Scopus and Medline databases. Resulting article abstracts and full texts were screened to determine final inclusion. Eighteen articles were included from the initial search. There is still little evidence to support the use of one type of crowns over another for primary teeth, in particularly for ZCs, lately introduced in pediatric restoration. The gold standard for restoring decayed primary teeth is still represented by SSCs, despite the growing importance of the aesthetic issue related to their use. Aesthetic ZCs resulted in having adequate properties to be employed for the treatment of decayed primary teeth, such as mechanical resistance, limited plaque adhesion, wear behavior and natural appearance. There is still a paucity of literature clinically evaluating the efficacy of ZCs for primary teeth restoration, but they can be considered a promising alternative to SSCs. This field of research has to be more deeply explored to improve dental care in children affected by early childhood caries.
BACKGROUND: The infraorbital foramen (IOF) is an essential anatomical structure for maxillary block anesthesia in dental practice and maxillofacial surgery. The literature also reports the importance of knowing the morphometric characteristics of the IOF because it can be damaged. The aim of our study was to determine anthropometric characteristics of infraorbital foramen in Senegalese population in relationship with the sex. METHODS: A total of 87 CT-Scan of patients were included in our sample and data collected from patient's cerebral CT-Scan. The transverse and vertical diameters of the IOF and its distance to the nearest point of the infraorbital margin, lateral nasal border and lower border of the maxillary were measured, and the shape determined. RESULTS: Eighty-seven CT-scan of patients were analyzed. This research showed that the transverse diameter of the left IOF in female subjects was 5.05 +/- 0.205 and 4.97 +/- 0.22 in male patients. The mean vertical diameter of the right foramen found in our study was 5.30 +/- 0.191 for the female subject and 5.28 mm +/- 0.137 for the men foramen was located at 46% on the line above the 2nd premolar. The right IOF was round in 52% of subjects. An accessory IOF was found in 20% of female subjects. CONCLUSIONS: Knowledge of the precise anatomical location of IOF is important in surgical procedures and reduce the relative risks during clinical procedures. This study showed many differences in the location of the IOF with Caucasians measurements done.
Background Most nasal cutaneous malignancies occur on the caudal third of the nose. Commonly, following resective surgery, the surgeon is requested to reconstruct the ala. Small skin defects of the nose may be left healing by secondary intention, although this may sometimes create an unpleasant scar. In the present paper we describe a 1-step reconstruction of the distal area of nasal ala, alar facial sulcus and cheek, with a segmented melolabial interpolated flap. Methods A 59-year-old man was operated for basal cell carcinoma involving the distal area of nasal ala and alar-cheek sulcus. The reconstruction was performed in 1-stage with a segmented melolabial interpolated flap used to reconstruct the anatomical missing subunits. Results Tumor-free margin was larger than the infiltrating region. No postoperative complications were observed. Conclusions The melolabial flap is a suitable option for the reconstruction of the nose, although the reconstruction of nasal ala is usually performed in 2-steps: the first one is performed to transfer the tissue and close the defect; the second, is performed to reshape the convexity of the ala and the concavity of the alar facial sulcus. In the present case, we do not perform a 2-steps reconstruction, we just reshaped the flap to perfectly fit the defect in 1-stage. The flap, supplied by collateral arteries from the facial and angular arteries, could be segmented for a better surgical outcome also during the harvesting stage if multiple anatomical subunits have to be reconstructed, with no need of a second surgical step that could be frustrating for the patient.
Objective Odontogenic keratocyst (OKC) can be classified as an oral lesion representing the third most common cyst of the jaws characterized by a high rate of recurrence. OKC was accepted as a neoplastic lesion in the 2005 WHO classification and it was called keratocystic odontogenic tumor (KCOT). However, in the 2017 classification of odontogenic tumors, OKC was moved back into the cyst category. This study aims to evaluate clinically, radiographically and through the histological examination the healing of a patient with OKC who underwent surgery with a marsupialization approach. Design An 83-year-old female patient, presented deformation of the right hemi-mandibular region and paresthesia of the right hemi-labium, during intraoral examination it was possible to detect an eggshell crackle on palpation of the anterior edentulous mandible, moreover, the patient reported a growth of the lesion over time that prevented her from using the removable prosthesis. Methods At the OPT it was possible to appreciate a unilocular area that extended from the parasymphyseal region to the right hemi-mandible. The CT scan showed massive erosion that only partially spared the lower cortex and involvement of the mental foramen. Results Checks following surgery show healing also confirmed by instrumental check-ups. Conclusions Surely this study offers a valid alternative to more invasive and debilitating surgical treatments.
