Bei einem 6-jährigen Patienten mit einem nachgewiesenen kutanen Lichen ruber zeigte sich eine retikuläre Streifung an der Oberlippeninnenseite und eine Hyperpigmemtierung der attached Gingiva. Oraler Lichen planus ist bei Kindern sehr selten, die Prävalenz bei Erwachsenen liegt bei 0,5-2% der Allgemeinbevölkerung und < 2-3% der Gesamtzahl sind Kinder. Aufgrund der Beschwerdefreiheit des Patienten erfolgte keine Therapie, eine regelmäßige Verlaufskontrolle wurde empfohlen. Obwohl OLP bei Kindern als selten gilt, sollten Behandler bei einer nicht abwischbaren weißen Läsion Lichen planus als mögliche Differentialdiagnose berücksichtigen.

Ein Hyperparathyreoidismus führt in 2-3 % der Fälle zur Entwicklung eines braunen Tumors, der sich überall im Skelett manifestieren kann. Durch das erhöhte Parathormon kommt es zu einer erhöhten Aktivierung der Osteoklasten sowie zum Anstieg von Kalzium und Phosphat. Die Knochenresorption überwiegt der Knochenneubildung. In der Folge bildet sich ein riesenzellhaltiges Gewebe, das die physiologische Knochenstruktur ersetzt und radiologisch nachweisbare Osteolysen bilden.
Im vorliegenden Fallbeispiel stellte sich eine 65-jährige Patientin mit derber, nicht verschieblicher, leicht druckdolenter Schwellung in regio 32-44 vor. Im CT zeigte sich ein unscharf begrenzter, osteolytisch-sklerotischer Prozess, der bis an den Unterkieferrand reichte. Die Diagnosesicherung erfolgte über eine Knochenbiopsie. Histologisch typisch sind mehrkernige Riesenzellen, Spindelzellen und Blutungsherde, die sich durch die Freisetzung von Hämosiderin organisieren, daher die Bezeichnung "braune Tumore“. Differentialdiagnostisch kommen andere riesenzellhaltige Läsionen wie: das zentrale Riesenzellgranulom oder die aneurysmatische Knochenzyste in Frage. Zur Diagnosefindung müssen daher zusätzlich Laborparameter herangezogen werden. Ursache des primären Hyperparathyreoidismus ist, wie auch im beschriebenen Fallbeispiel, in 80% der Fälle ein Nebenschilddrüsenadenom.
Die Therapie bestand in der Entfernung der Nebenschilddrüse. Dadurch kam es auch zur Rückbildung der knöchernen Läsion, so dass diese nicht weiter chirurgisch behandelt werden musste.

Probiotics are defined as viable microorganisms that confer a health benefit when administered in sufficient doses. A few studies have revealed that probiotic Lactobacillus strains were useful in reducing gingival inflammation and the number of black-pigmented rods, including Porphyromonas gingivalis (Pg), in the saliva and subgingival plaque. The aim of this study was to evaluate the effects of scaling and root planing (SRP) alone or SRP in combination with Lactobacilli casei in patients with chronic periodontitis. The study population comprised 20 patients who were randomly allocated into a control group (scaling and root planning was done) and the test group (scaling and root planing along with probiotic milk drink supplementation (65 ml) containing Lactobacillus casei strain once per day for one month). The clinical examination included a full-mouth periodontal assessment: BOP (bleeding on probing), PI (plaque index) and GI (gingival index) at baseline and after one month. GI & BOP were significantly decreased in Group B as compared to Group A at one month. Non-significant differences were seen in other periodontal parameters between Group A & B. The patients taking probiotic milk drink as an adjunct to scaling and root planing demonstrated a better improvement in gingival inflammation. However, a further long term, multi-centre study with a large sample size is recommended to determine its practical implementation.

Rehabilitation of mucormycosis patientsMaxillectomy is the surgical removal or resection of the maxilla or upper jaw bone. Maxillectomy is performed during surgical treatment for cancer and infections of the oral cavity, nasal cavity and maxillary sinuses. Patients affected by post-COVID mucormycosis require an aggressive surgical resection resulting in partial or complete maxillectomy. The oronasal communication following resection affects mastication, speech, and swallowing and has a profound psychological impact on the patient. Patients affected by post-COVID mucormycosis reported for definitive rehabilitation following partial or total maxillectomy. Partial maxillectomy patients were rehabilitated with a DMLS designed metal framework along with semi-precision attachment and hollow obturator fabricated using lost salt technique, whereas the complete maxillectomy patient was rehabilitated with a magnet-retained two-part prosthesis (Part I: 3D printed Palatal obturator and Part II: conventional complete denture). 3D printing comprises data acquisition through various scanning technologies followed by data processing and designing the model with computer-aided design (CAD) software. Additional manufacturing through 3D printing provided various advantages such as accuracy, detail reproduction, reduced wastage of material, easier reproduction of complex structures as compared to the conventional approach. ln this presentation both conventional and digital approaches were used for the fabrication of prostheses. The ultimate goal is to provide a retentive and stable prosthesis to help patients overcome the social and psychological predicaments.

Veneers for AestheticsCeramic veneers are well known as a conservative treatment option for anterior teeth presenting wear, fractures, interdental spaces, and facial defects. Bonded ceramic veneers have been proven to show reliable outcomes with positive long-term results. A 20-year-old female patient reported with the complaint of discoloured and fractured anterior teeth and wanted cosmetic rehabilitation for the same. A treatment plan of ceramic veneers for maxillary canine to canine (13-23) was advised and carried out. A 28-year-old male patient reported with the complaint of midline spacing in upper front tooth region. Ceramic veneers for maxillary central incisors (11-21) were planned as he declined the orthodontic corrections. Nowadays, ceramic veneers have reached a very high level of quality: the parameters of tissue economy, aesthetics, and function are no longer antagonistic. Hence, ceramic veneers should be our first option when establishing a treatment plan for aesthetic regions.

Ameloblastic carcinoma is a rare odontogenic tumour that is aggressive with extensive local bone destruction. It retains the features of ameloblastic differentiation and also exhibits cytological features of malignancy. The characteristic histologic features and behaviour dictate a more radical surgical approach than does simple ameloblastoma. It occurs primarily in the posterior mandible in a wide range of age groups. It may arise de novo (primary type) or by malignant transformation of ameloblastoma (secondary type) with a distinction between carcinoma ex intraosseous ameloblastoma and carcinoma ex peripheral ameloblastoma. Histologically, it is characterized by areas with features of typical ameloblastoma and areas with anaplastic appearances. The purpose of this report is to present a case of ameloblastic carcinoma of the anterior mandible in a 55-year-old female patient with a clinical course of typical aggressiveness and extensive local destruction.

Background: Amelogenesis imperfecta (AI) is a group of genomic developmental disorders that can affect the structure and clinical appearance of the enamel of all or almost all teeth. They can affect both the primary and permanent dentition. Not only are patients aesthetically compromised by the altered enamel, but in severe cases the exposed dentin can exacerbate carious lesions. This case report shows an all-ceramic restoration in a young female patient.
Case report: At the time of presentation to the Department of Prosthodontics at the University Hospital of Münster, the patient was 28 years old. Since 2010, carious lesions had been repeatedly treated with composite fillings due to the diagnosis of amelogenesis imperfecta (hypoplastic type 1). As the fillings had to be replaced regularly and the patient had already suffered a moderate loss of bite height of approximately 4 mm, a bite augmentation was planned by crowning all teeth with all-ceramic crowns.
The new bite height was first tested with long-term PMMA temporaries. After preparation of all teeth, these were placed in 6 blocks and worn for 3.5 months. The patient showed no problems after the wearing period. Therefore, the new bite height was transferred to all-ceramic crowns for the final restoration. Monolithic zirconia crowns were used in the posterior and mandibular anterior regions, and zirconia frameworks were veneered in the maxillary anterior region to improve aesthetics.
Discussion: A few cases of restorations in patients with amelogenesis imperfecta have been described in the literature. In less severe forms, composite abutments or veneers can be used to treat the enamel malformation. As enamel may be completely absent in type 1, crowns are the treatment of choice. A full crown prevents future substance loss and provides the best possible protection for the remaining tooth substance. With modern all-ceramic restorations, highly aesthetic results can be achieved even in severe initial conditions.
