“…Several studies, including the present study, have demonstrated the effect of ARP specifically in molar areas (Cha et al, ; Lombardi et al, ; Walker et al, ; Zhao, Xu, Hu, & Chung, ). All of these studies favoured ARP over natural healing in terms of maintaining ridge dimension, but high heterogeneity among studies should be considered (Cha et al, ; Lombardi et al, ; Walker et al, ; Zhao et al, ), such as jaw and socket morphology, biomaterial, surgical technique (flap reflection and primary flap closure), healing period, and measurement (reference line and measurement level). Concerns over such heterogeneity were also stated well in recent systematic reviews (Avila‐Ortiz et al, ; Bassir et al, ; Troiano et al, ).…”

Aim To determine the effect of alveolar ridge preservation (ARP) in molar sites without primary flap closure. Materials and Methods Three groups were established: extraction sockets grafted with deproteinized bovine bone mineral containing 10% collagen (DBBM‐C) and covered by a native bilayer collagen membrane (NBCM) (test group 1), sockets grafted with DBBM‐C only (test group 2), and sockets that healed naturally (control group). Primary flap closure was not attempted. Conebeam computed tomography scans were obtained immediately and then 4 months after ARP. A biopsy was performed. The change of the marginal bone level was measured. Results There was significantly less horizontal resorption in test group 1 than in the control group at levels 1 mm (−1.02 ± 0.88 [mean ± SD] vs. −4.44 ± 3.71 mm) and 3 mm (−0.31 ± 1.51 vs. −2.27 ± 1.15 mm) below the crest, and significantly less vertical reduction in the midcrestal area in test group 1 than in test group 2 (−0.25 ± 0.95 vs. −1.15 ± 1.63 mm) (p < .05). There were no significant differences between test groups in clinical and histomorphometric measurements. All groups exhibited stable marginal bone levels after 1 year of loading. Conclusion Alveolar ridge preservation without primary flap closure in molar areas was effective in minimizing ridge resorption and facilitated implant treatment.

“…Extracting the second molar can cause cortical bone fractures between the root end and the maxillary sinus. Thus, the extraction of second maxillary molars is considered to cause excessive sinus pneumatization [2,[7][8][9]. In the present study, greater sinus pneumatization was observed after the extraction of first molars.…”

“…Currently, cone-beam computed tomography (CBCT) is a common diagnostic tool that supports threedimensional (3D) imaging and provides thin, detailed sections to assess the relationship between the maxillary sinus floor and the alveolar bone ridge. Although this method reduces the overlapping of anatomical structures and enables a better assessment, a few studies used CBCT to analyze sinus floor pneumatization in the posterior maxilla [1,2,[7][8][9]. The purpose of this study was to determine the amount of sinus pneumatization after the extraction of maxillary teeth in the premolar and molar regions associated with the maxillary sinus via the evaluation of panoramic views.…”

Purpose Maxillary sinus pneumatization following teeth extraction may require various treatment plans such as sinus lifting and alveolar grafting procedures to obtain sufficient alveolar bone height for implant surgery. The aim of this study was to identify sinus pneumatization and to help in determining the proper time for preprosthetic surgery following extraction of maxillary sinus related teeth. Methods We evaluated 75 teeth extraction related to maxillary sinus floor. The panoramic radiographs were evaluated before and after extraction of the posterior maxillary teeth. The radiographs were divided into 5 groups according to duration after extraction. Two reference points (the first point corresponds to the nasal spine while the second point corresponds to the most inferior point of the floor of the maxillary sinus wall) were determined on digital panoramic radiographs before and after teeth extraction and the distance between both aforementioned points was measured. Results The amount of pneumatization was found to be increased with time. The pneumatization within the first 6 months was limited. However, a sudden increase of pneumatization after 6th month, especially the highest between 18th and 24th months, was observed. The mean pneumatization amount was found to be highest in the 1st molar group. Conclusion According to the results of the present study, surgeons should not be waited any more than 6 months after tooth extraction for preprosthetic surgery in the posterior maxillary region as long as physiological healing of extraction socket is allowed.

“…Only one study reported a relapse of the disease 2 weeks after a first surgery consisting of local excision with maxillectomy [38], while 4 studies made no reference to recurrence [32][33][34]40]. These invasive surgeries often require post-surgical rehabilitations [51,52], and in some cases are made complex by the presence of local contraindications (noble anatomical structures [53][54][55][56], or systemic contraindications (general health conditions of the patient [22][23][24]26,57]). Post-surgical and infection management are important [27,28,30].…”

Malignant fibrous histiocytoma is one of the most common soft tissue sarcomas in adults. It occurs only occasionally in oral soft tissues, and knowledge about its characteristics is based on a limited number of cases reported in the literature. Malignant fibrous histiocytoma belongs to the group of soft tissue sarcomas and makes up less than 10% of soft tissue sarcomas. For therapeutic purposes, complete exeresis of the lesion (macroscopic and microscopic) is performed because they have frequent recurrences. As for complementary therapy in addition to surgery, neither radiotherapy nor chemotherapy have been shown to reduce the risk of death related to the disease. Often patients complain of a swelling that grows in a short period of time. It is quite common for patients to report trauma in the area, which is not the cause, but rather the event that allows diagnosis. The mass usually does not cause pain unless it compresses an adjacent nerve structure. The aim of this study is to systematically review the scientific literature in order to identify the most recent studies concerning malignant fibrous histiocytomas localized in oral soft tissues and report their main data. The main outcomes of this study concern the immunohistochemical, molecular, and clinical aspects of this pathology. A systematic review of articles in the electronic databases pubmed, Scopus, and Web of Science was performed. After the selection process, 11 studies met the inclusion criteria and were included in the review. The mean age of the patients was 50.8 years old. The lesions affected various parts of the oral cavity, showing predominantly storiform–pleomorphic patterns. All cases except one were treated with surgical resection and radiation therapy. Although some data emerged from this review, they remain limited to a few case reports. Further studies are necessary in order to standardize the approach to patients affected by oral malignant fibrous histiocytoma (MFH).
