Abstract
Oral lichen planus (OLP) is a chronic inflammatory disease whose pathogenesis involves a T-cell mediated, epithelium-directed inflammation in response to unknown antigen(s). The disease evolves by intermittent flares and displays polymorphous clinical features (reticular, erosive, atrophic, plaque, papular, bullous, etc.). When present, symptoms vary depending on the clinical form and range from discomfort to severe pain. Topical superpotent corticosteroids constitute the first-line treatment of symptomatic flares, whereas a wide range of second/third-line treatments are available among topical calcineurin inhibitors, systemic corticosteroids, systemic retinoids, topical/systemic immunomodulators, etc. Follow-up of patients is necessary to detect transformation into squamous cell carcinoma, occurring in approximately 1% of patients.

Abstract
BACKGROUND Plasma cell gingivitis is defined as gingival inflammation comprised of plasma cell infiltrates. This diagnostic criterion is non-specific and underlying mechanisms remain unknown. OBJECTIVES We performed a multidisciplinary clinico-pathological review of cases previously identified as "gingivitis with plasma cell infiltrates", with assessment of putative contributing factors and critical appraisal of the final diagnosis. MATERIALS & METHODS Cases previously identified as "gingivitis with plasma cell infiltrates" between 2000 and 2020 were included from archives from the GEMUB group, a French multidisciplinary network of physicians with expertise on oral mucosa. RESULTS Among the 37 included cases, multidisciplinary clinico-pathological review allowed differential diagnosis in seven cases (oral lichen planus n=4, plasma cell granuloma n=1, plasmacytoma n=1, and mucous membrane pemphigoid n=1). The remaining cases were classified as "reactive plasma cell gingivitis" (induced by drugs, trauma/irritation or periodontal disease) (n=18) or "idiopathic plasma cell gingivitis" when no contributing factors were identified (n=12). Clinico-pathological characteristics did not differ significantly between "reactive" and "idiopathic" cases, preventing us from identifying specific features of "idiopathic" plasma cell gingivitis. CONCLUSION "Plasma cell gingivitis" is a polymorphous, non-specific entity with various aetiologies, of which the diagnosis requires multidisciplinary anatomo-clinical correlation for exclusion of secondary causes of plasma cell infiltration. Although our study was limited by its retrospective design, most cases of "plasma cell gingivitis" appeared to be associated with an underlying cause. We propose a diagnostic algorithm to properly investigate such cases.

Abstract
BACKGROUND/AIMS Interleukin 33 (IL-33) plays a significant role in immunity but its role in bone physiology and periodontitis needs to be further investigated. The aim of this study was to decipher the contribution of IL-33 to bone homeostasis under physiological conditions, and to alveolar bone loss associated with experimental periodontitis (EP) in IL-33 knockout (KO) mice and their wildtype (WT) littermates. METHODS The bone phenotype of IL-33 KO mice was studied in the maxilla, femur, and fifth lumbar vertebra by micro-computed tomography (micro-CT). EP was induced by a ligature soaked with the periopathogen Porphyromonas gingivalis (Pg) around a maxillary molar. Alveolar bone loss was quantified by micro-CT. The resorption parameters were assessed via toluidine blue staining on maxillary sections. In vitro osteoclastic differentiation assays using bone marrow cells were performed with or without lipopolysaccharide from Pg (LPS-Pg). RESULTS First, we showed that under physiological conditions, IL-33 deficiency increased the trabecular bone volume/total volume ratio (BV/TV) of the maxillary bone in male and female mice, but not in the femur and fifth lumbar vertebra, suggesting an osteoprotective role for IL-33 in a site-dependent manner. The severity of EP induced by Pg-soaked ligature was increased in IL-33 KO mice but in female mice only, through an increase in the number of osteoclasts. Moreover, osteoclastic differentiation from bone marrow osteoclast progenitors in IL-33-deficient female mice is enhanced in the presence of LPS-Pg. CONCLUSION Taken together, our data demonstrate that IL-33 plays a sex-dependent osteoprotective role both under physiological conditions and in EP with Pg.

Abstract
BACKGROUND This study aimed to describe the surgical technique of reverse frontal cranioplasty (RFC), the aesthetical modification as well as the modification of intracranial volume (ICV) to assess its potential eligibility for the treatment of the intracranial hypertension (IH). MATERIALS AND METHODS A retrospective monocentric study included the patients with a history of craniosynostosis with a forehead deformity who underwent RFC. A subjective outcome questionnaire (SOQ) was conducted with each patient or their parent to determine their level of satisfaction after RFC. Pre- and postoperative computed tomography (CT) scans were analyzed and compared to investigate the ICV change and fronto-nasal angle. RESULTS Eleven patients were included in the study (6 female and 5 male) with a mean age of 10.9 years old (range 3-23 years) and an average follow-up of 4.5 years (1-11 years). All patients responded to the questionnaire with a high level of overall satisfaction (mean 9.1/10). The mean preoperative FNA was 134° ± 5° while the mean postoperative angle was 126.4° ± 6, corresponding to an average decrease of 7.6° (95% CI, 4.0-11.2°; p < 0.001). One patient with preoperative IH had a clinical recurrence during the follow-up. The ICV was significantly higher after the surgery (p < 0.0001), with an average increase of 3.2% (95% CI, 2.3-4.1%). CONCLUSION Reverse (RFC) is a useful technique for the correction of the frontal malformations related to craniosynostosis, such as a sloping forehead and/or a lack of the supraorbital projection. Regarding the limited gain of intracranial volume (ICV), it should not be used alone as primary cranial expansion surgery for craniosynostosis with intracranial hypertension (IH).

Abstract
INTRODUCTION Abalakov is a mountaineering technique consisting in drilling two holes that intersect to form a V in order to thread a rope through to make an anchorage point. This technique can be applied to orthodontic treatment and constitutes a posterior mandibular orthodontic anchorage. TECHNICAL NOTE The technique can be performed on its own during local anaesthesia or during surgery for the extraction of wisdom teeth. The posterior anchorage point is located in the ramus of the mandible. It consists in drilling two holes that intersect to form a V and then threading a steel wire through to make an anchorage point. DISCUSSION This technique is simple, inexpensive, fast and non-invasive, providing an anchorage system with immediate loading and which is not dependent on the quality of the bone.

Abstract
BACKGROUND Patients with Crouzon syndrome are mainly treated in childhood by frontofacial monobloc advancement to avoid ophthalmic, neurologic, and maxillary complications. There is no reported case of surgery on adult patients with Crouzon syndrome in the literature. However, when faced with 2 cases of adult patients showing severe quality of life deterioration, our team decided to make an attempt using monobloc advancement technique. CASE DESCRIPTION Two women aged 41 and 56 presented with untreated Crouzon syndrome and suffered from exorbitism, intracranial hypertension with chronic headaches, and hypoplastic maxillary. We decided to perform frontofacial monobloc advancement with internal distraction despite their advanced age using planned surgery and cutting guides. Distraction began 7-10 days after surgery and was of 15 mm. Distractors were taken off at 6 months. Surgical treatment corrected chronic headaches, ocular symptoms due to exorbitism, and hypoplastic maxillary. Patients were satisfied with the functional and aesthetic results. We noticed that this heavy surgery was more difficult to bear by these adults than children. CONCLUSIONS Adults with craniofacial malformations have a lower self-esteem, lower quality of life, and less satisfaction with their facial look as compared with individuals without facial malformations. There is also an increased risk of psychosocial problems. Despite postoperative difficulties and minor complications, our 2 patients were satisfied with the functional and aesthetic results. This led to the conclusion that surgically addressing adult patients with Crouzon syndrome via monobloc advancement is appropriate and secure when performed by a trained team.
