Beauty, it seems, is a fascination inherent in human nature. Research shows that an attractive face plays a significant factor in human life, such as in the areas of appreciation and judgment.The growing demand for cosmetic treatments is amplified by social media and influencer marketing. However, there are possible negative effects, such as addiction and dissatisfaction with treatment outcome in people with Body Dysmorphic Disorder. It remains important to recognize that risks are inherent in medical procedures.

The caries prevalence in patients with cleft lip and/or palate is higher in both the deciduous and permanent dentition, compared to non-cleft patients. Inadequate oral hygiene is one of the main causes. Additional, individualized advice concerning diet and oral hygiene, such as the additional advice of the Ivoren Kruis (Dutch association of dental hygienists), is of great importance. During curative treatment, attention should be paid to any dental anxiety and possible reduced compliance.

A 51-year-old woman was referred to a periodontology practice for treatment of advanced generalized periodontitis stage IV, grade C. When the dental hygienist treated the distal surface of tooth 17 with the ultrasonic scaler, the patient indicated she heard a painful, high tone. The dental hygienist immediately stopped the treatment. At a subsequent attempt to treat the same distal surface, the patient heard a painful, high tone again. After two weeks, the high tone had not disappeared. The patient was referred to an ENT specialist. He confirmed the diagnosis: tinnitus in the right ear. Pharmacological treatment with prednisone did not produce a positive result. Ultrasonic treatment of periodontitis is generally considered safe. However, in exceptional cases, sudden deafness and/or tinnitus can occur. In the event of such complaints, it is recommended not to wait, but to refer the patient to an ENT specialist immediately.

In every dental practice, patients present with persistent physical symptoms. Such complaints can significantly complicate dental treatment, especially if they are not acknowledged, or if the patient feels they are not being taken seriously. For this reason, it is important to increase oral care providers' knowledge and expertise concerning persistent physical symptoms in a broader sense and in the head and neck area in particular, with the aim of improving the treatment alliance and to increase the effectiveness of dental treatment.

In this retrospective study, 2 intraoral scans with an interval of at least 1 year were superimposed in 25 oligodontic patients. The differences in vertical eruption (mm) were measured and the orthopantomograms were analyzed for the presence of ankylotic deciduous molars with no successor. The mean eruption of deciduous molars with and without successor was significantly lower than the mean eruption of permanent molars. The eruption of permanent molars was a predictive variable for the eruption of deciduous molars. The number of agenetic elements and the presence of a successor were strongly associated with the eruption of deciduous molars. Also, the mean eruption of deciduous molars with ankylosis was significantly lower than that of deciduous molars without ankylosis. This study showed a strong relationship between the diagnosis of ankylotic deciduous molars and the measurement of negative vertical eruption when monitored by intraoral scans.

Subgingival restorations are problematic due to reduced visibility at the preparation margins, humidity (saliva, crevicular fluid and/or blood), problems with taking impressions (digital or analogue) and problems with the application of a rubber dam. Solutions, such as the use of a surgical microscope, retraction cord and Teflon tape, are available. Since modern dentistry largely relies upon adhesive techniques with hydrophobic materials, these require a clean and dry working area. One solution is to place the preparation margin supragingivally. This can be done in three ways: a local build-up using a direct composite restoration, a surgical clinical crown lengthening or an extrusion (orthodontic or surgical). Since in practice only a small part is usually located subgingivally, placing a direct composite restoration is often sufficient. The term Deep Margin Elevation is generally used in the international English-language literature for this approach. If the area located subgingivally is larger, then techniques like crown lengthening and extrusion might be better.

Unfortunately, accidents do happen. Dentoalveolar injury to the front teeth resulting from trauma can sometimes be so problematic that an (adhesive) restoration seems almost impossible to make, let alone saving the tooth. In this contribution the case of a 17-year-old patient whose upper incisor suffered severe dentoalveolar trauma in a traffic accident is presented. His upper incisor was fractured deeply subgingivally, at bone level, and at first glance, appeared to be lost. Surgical extrusion, however, in this patient represents a full alternative to a prosthetic solution, such as a dental implant.

With the advent of adhesive dentistry, tooth preparation can be minimally invasive. An optimal adhesion to the dental tissues is a requirement. Rubberdam isolation, using a gold standard adhesive and bonding to freshly prepared dentin are all factors that improve the adhesion to tooth tissue. For non-retentive restorations, indirect composite and glass-ceramic materials are suitable. To date, several studies have shown a high survival rate of indirect adhesive restorations. The adage "if you can isolate the tooth, you can preserve it" may guide the choice of starting an adhesive procedure.

The presence of subgingival pathology, such as a deep secondary caries lesion, a fracture, an already existing restoration that needs to be replaced or the presence of a resorption defect, can constitute a difficult starting situation for the preservation of a tooth. How to deal with such a situation has been a topic of discussion for years. Surgical crown lengthening is one of the first and classic treatment options that is often chosen in such cases. Crown lengthening is a periodontal surgical technique to obtain extra supra crestal clinical crown length. The question is, what is the long-term prognosis of teeth after surgical crown lengthening. To answer this question, a review of the literature was carried out looking for clinical studies examining survival. Four studies with a follow-up of at least 5 years were included. The factors that adversely affect survival of the tooth after the crown lengthening are an unfavourable crown-root ratio, insufficient plaque control and moderate ability to keep the restoration clean.

A young woman, known to have glycogen storage disease type 1B (GSD1B) presents with severe periodontitis. GDS1B causes decreased hepatic and renal glucose production and in many cases neutropenia and neutrophil dysfunction leading to recurrent infections. It was decided to treat the patient by extraction of the most affected teeth and retention of the remaining teeth through periodontal treatment, both with antibiotic prophylaxis. After a follow-up period of 1.5 years, during which there was no visible improvement, it was decided to do a full dental extraction and fabricate complete dentures. Due to subsequent bone resorption in both jaws, the dentures were not functional. After consulting the internist and the oral and maxillofacial surgeon, the decision was then made to place dental implants in both the upper and lower jaw for implant-supported prosthetics. After successful treatment and an osseointegration period, the prosthetics were placed. 1 year after placement, there is a stable implantological situation, without pockets or apparent bone loss. The start of SGLT2 medication may have played a significant role in this.
