After a fall from his wheelchair, a 23-year-old wheelchair-dependent patient with spinal muscular atrophy type 1 was initially seen by an emergency dentist, who repositioned and splinted the luxated teeth number 31 and 32. For stabilization, the patient was subsequently referred to a centre for special dental care. In the past, few treatments had been carried out on the patient. A jaw defect and very limited mouth opening compromised dental treatment. In addition, due to the muscle disease, the patient had respiratory and breathing problems, for which he used respiratory equipment. This case describes the importance of a multidisciplinary team in the treatment of patients with spinal muscular atrophy, and the options for performing minimally invasive dental treatment, where the priority is a painless dentition.

Matrix metalloproteinases (MMPs) are enzymes involved in the remodelling and degradation of the extracellular matrix, which is essential for maintaining healthy oral tissues. It is therefore important for dental students to know the role of MMPs in biological processes and diseases. Using a questionnaire, a cross-sectional study was conducted among master's dental students from 3 universities in the Netherlands and Belgium. The general level of knowledge about MMPs of the 80 respondents was predominantly low (91.3%). Significant differences were observed among students from the various dental schools, with students from the University of Groningen and Ghent University scoring significantly higher than those from the Academic Centre for Dentistry in Amsterdam (ACTA). Gender was associated with a few questions on the relationship between MMPs and dentistry, with female students achieving higher scores. Improving dental curricula regarding MMPs and their role in dental processes seems warranted.

Duchenne muscular dystrophy is a hereditary progressive neuromuscular disorder. Deterioration and weakening of the muscles is also present in orofacial muscles. Both weakness of the muscles and the fact that patients become more dependent of care, can make oral care more difficult. At this moment, it is unknown how patients with Duchenne muscular dystrophy experience their oral health and which problems regarding oral health and oral care may impact their oral health related quality of life. In this cross-sectional study, we found that, despite a high percentage of gingivitis, a high percentage of patients who experience halitosis and a high percentage of malocclusions, patients score their oral health related quality of life as good.

Many older individuals with dementia show care-resistant behavior for oral care. Providing care despite resistance is considered to be involuntary care. The Dutch law, 'Wet zorg en dwang' (care and coercion), states that care must be ceased in the presence of resistance, unless there is (a risk of) serious harm. This study was conducted to gain insight into the attitudes of healthcare providers with regard to involuntary oral care in older individuals with dementia. An online questionnaire consisting of general questions, case specific questions and knowledge questions about the Dutch law was filled out by 392 care providers. In all cases, a discrepancy was seen between the assessment of oral health problems as potentially harmful and the willingness to provide involuntary oral care. Hence, many healthcare providers are aware of the subsequent potential health risks related to not providing care, but are still reluctant to provide involuntary oral care. A large part of the healthcare providers also has a low level of knowledge with regard to the Dutch law 'Wet zorg en Dwang'.

Surgical procedures that rejuvenate and/or harmonize the face are known for their long-lasting and clinically relevant positive effects on the psychological well-being and quality of life of the client. Despite the popularity of cosmetic injectables, facelift surgery remains the most powerful and durable treatment for restoring aging symptoms, especially in the female face. Skin correction of the upper eyelids is the most commonly performed aesthetic facial surgery. This article provides an overview of the most important cosmetic surgical procedures for the face, focusing on the facelift, neck lift, forehead lift, upper and lower eyelid correction, subnasal lip lift and rhinoplasty. The indications, contraindications, treatment techniques, advantages and disadvantages are explained. Due to the increasing demand for cosmetic treatments, it is important that dentists and oral and maxillofacial surgeons have knowledge of these procedures in order to provide optimal information, referral or treatment when desired.

Botulinum neurotoxin type A (BoNT-A, popularly referred to as 'botox') is a muscle-relaxant that is injected into the mimic facial muscles to soften wrinkles in more than two percent of Dutch women annually. A similar number of women undergo filler injections with hyaluronic acid hydrogels, used to counteract the aging appearance of the skin, or to create desired facial contours. Complications are generally mild in nature and rare (certainly compared to surgical complication rates) and include nodules, bumps and a temporary heavy feeling of the eyebrows. Vascular complications related to filler injections (1:7000) can potentially lead to unilateral blindness or skin necrosis. In the Netherlands, the risk of blindness over the past six years is estimated to be 1 in every 1.4 million filler injections. Permanent skin damage due to gangrene has never been reported in the Netherlands. In conclusion, BoNT-A and hyaluronic acid filler injections are safe procedures in the hands of appropriately trained healthcare professionals.

Bruxism is a disabling condition in which unconscious contractions of the masticulatory muscles lead to teeth grinding and jaw clenching. Symptoms include toothache, temporomandibular dysfunction, headache and attrition. Treatment options range from conservative approaches to invasive interventions. Education, stress reduction, avoidance of stimulants, and relaxation techniques can help in mild cases. Wearing an occlusal splint can reduce attrition. Botulinum neurotoxin type A (BoNT-A) injections are a treatment option temporarily causing partial paralysis of the masticulatory muscles. BoNT-A is a treatment for reducing symptoms and improving the quality of life of patients with bruxism that has been proven safe and effective. The effects usually last several months. To achieve the best results and minimize side effects, BoNT-A injections should be applied by an experienced practitioner.

A recent survey indicates 49% of this journal's subscribers endorse the administration of cosmetic injectables by properly trained dentists. Given the surging demand for cosmetic treatments, it's essential to establish clear guidelines and conventions defining the roles of the various healthcare professionals in various situations. There is, however, considerable discussion still and from a legal standpoint, the role of dentists within cosmetic medicine remains ambiguous. Under the Dutch Individual Healthcare Professions Act (Wet BIG), dentists are authorized to administer cosmetic injectables exclusively for dental purposes. However, based on the content of current dental training, one might argue that dentists' authorization could be extended to include facial injectable treatments in the entire face, in future. Presently, it is prudent for general practice dentists to abstain from cosmetic procedures with cosmetic injectables without a specific (aesthetic) dental objective.

The use of dermal fillers for cosmetic procedures has increased rapidly both worldwide and in the Netherlands in recent years, which has led to an absolute increase in reported side effects and complications. Although most of these complications are mild, serious complications such as vascular occlusion can also occur. In this article, we describe a case of a 35-year-old woman who showed signs of reduced tissue perfusion and the early stage of skin necrosis following injection of hyaluronic acid fillers in the chin. This complication was successfully treated by ultrasound-guided injection of hyaluronidase, resulting in a full recovery without residual symptoms. To minimize the risk of serious complications treatment with hyaluronic acid fillers should be carried out by an experienced practitioner.

In addition to function, occlusion and airway volume, aesthetics play an important role in the planning and execution of orthognathic surgery. To improve the aesthetic outcome of orthognathic surgery, there are several procedures that can be combined with orthognathic surgery secondarily, or in the same operation. These include: lipofilling, dermal fillers, facial implants, liposuction, ear corrections, eyelid corrections, or a lip lift. Patients often appreciate it when the options for additional procedures are discussed. However, both undertreatment and overtreatment can lead to unfavorable outcomes. Proper care and thoroughness are of course required, as to not change the characteristic facial aspects of a patient too much.
