The anaerobic microenvironment of the grooved tongue surface provides optimal conditions for the survival of microorganisms. These microbes may promote caries, periodontitis marginalis, periimplantitis as well as halitosis. A new device, the TS1 tongue vacuum cleaner, is designed to remove bacterial biofilm from the tongue’s surface. The aim of the present study was to both examine the acceptance of this tongue vacuum cleaner by children at the School Dental Clinic Basel as compared to a child’s manual tooth brush, and tongue cleaning at home for a 1-month period...

Pregnant women undergo several physiological changes – including when it comes to taking medication. Many substances, when taken by the expectant or lactating mother, will be transferred to the foetus or newborn, and not all drugs that help the mother will be beneficial for the baby. Especially in early pregnancy, during organogenesis, the foetus is highly sensitive. If this early development is disturbed by harmful substances such as certain medications, there can be serious consequences. In the worst case, the child is born with a malformation or is limited in its mental development...

Health care-associated infections may not only occur in a hospital setting, but also in dental clinics. Insufficient environmental decontamination could be one of the risk factors. In this retrospective study, we documented and analyzed the results of surface microbial contamination in a dental university-based department over an observation period of ten years. It was the aim of this investigation to identify general tendencies and potentially problematic sites on a long-term basis allowing suggestions for further improvement...

The aim of the present study was to measure unstimulated saliva flow rate (uSFR), pH value and buffer capacity in healthy children aged 6 to 15 years to serve as reference values for subsequent investigations, in particular to define threshold values for abnormality. Our basic data will power the limited amount of currently available data on salivary flow rate in healthy children. The uSFR was evaluated for correlations with pH value and buffer capacity. The unstimulated saliva of 274 children aged 6 to 15 years was collected (n: 154 v; 120 u) by the spitting method within three minutes...

Lyme borreliosis is a prevalent disease with a wide variety of clinical manifestations. However, only a few pertinent references are found in the dental literature. Considering the diversity of differential diagnoses, borreliosis-associated orofacial pain may be a challenge for treatment providers and patients alike. The aim of this case report is to emphasize the importance of a sound, structured medical history and assessment to identify severe cases early and to start interdisciplinary therapy if indicated...

In pregnancy, it is necessary to pay particu­lar attention to oral health, as inflammatory periodontal changes can occur due to the ex­ceptional hormonal situation. The popular be­lief, still existing today, that «each pregnancy costs the woman a tooth» is no longer valid considering conventional oral hygiene mea­sures and the fact that most pregnant women are very conscious of their nutrition (diet).

Reintegration of freshly extracted healthy teeth is very successful, most likely due to the regenerative capacity of their roots’ residual periodontal ligament (PDL). We hypothesised that in vitro cultures of the consecutive slices of a sectioned root will represent the entity of PDL cell types engaged in tooth-sided reintegration. For confirmation, apex and pulp from human premolars were removed and roots cut into 6 to 9 about 1 mm thick slices. These were immobilised to separate wells and cultured for 20 days, under daily inspection for the initiation of cell outgrowth (ICO)...

Children with attention-deficit hyperactivity disorder ADD/ ADHD are often difficult to be treated. If the anterior teeth have to be treated in case of trauma, the patient and the therapist quickly come to their limits. In the present case, with the help of the Cerec and composite partial veneers, an attempt was made to divide the treatment into two relatively short treatment periods for the patient. The two phases were interrupted by a longer construction and grinding phase. The composite partial veneers showed acceptable aesthetics...

Platelet-rich fibrin (PRF) is a blood concentrate system derived from human peripheral blood. A solid and a liquid PRF-based matrix can be obtained by centrifugation in accordance with specific centrifugation protocols without the addition of anticoagulants or external chemicals. In dentistry, oral- and cranio-maxillo-facial surgery, PRF-based matrices are used on different subjects. The healing benefits of platelet-rich preparations together with the low risk profile and disposability of a simple preparation procedure should encourage more clinicians to incorporate PRF as a treatment option in their practice to accelerate healing, reduce adverse events, and improve patient outcomes...

Effect of prosthesis and dental implants on quality of life related to the patient’s oral health can guide the clinician in providing best services. The zygomatic implant (ZI) is a partial or complete alternative technique to so-called traditional rehabilitation techniques (aiming to increase bone volume) of edentulous atrophic maxillae. The objective of this study was to evaluate the impact of fixed prosthetic rehabilitation by ZI on patients’ quality of life. This study highlighted the level of satisfaction of nine patients treated with ZI via their pre-therapeutic and post-therapeutic scores on the Oral Health Impact Profile (OHIP)-14 scale...

Prosthetic rehabilitation of the atrophic edentulous maxilla is a challenge for which zygomatic implants (ZI) stand out from traditional techniques (aiming to increase bone volume) with reduced treatment duration and immediate loading. The aim of this study was to review the ZI treatment plan and its surgical technique based on a series of nine edentulous atrophic maxillary cases. Implant survival rate and postoperative follow-up were reported as well as those described in the literature. The advantages and disadvantages of ZI versus traditional methods of rehabilitation in our daily work were also discussed...

We compared the prevention of erosive and erosive/abrasive enamel loss by a medical minerals gel system (R.O.C.S.) to that by an anti-erosive toothpaste. Seventy-two bovine enamel samples were randomly allocated to six groups (E1–E3 and EA1–EA3; n=12). Per day, samples were eroded (2 min) 9 times using HCl (pH 2.6). Between erosive challenges and over night samples were stored in artificial saliva. Per day, samples were stored (100 s; groups E1–E3) or additionally brushed (20 brushing strokes; groups EA1–EA3) in/with slurries prepared from artificial saliva plus: no additional toothpaste (control groups E1 and EA1), elmex erosion protection toothpaste (groups E2 and EA2), or R...

The individual appearance and facial expression are based on the musculoskeletal system of the face. The bones of the face contribute to the anterior portion of the skull. This region is also referred to as the facial skeleton or viscerocranium. The muscles of the face include all mimetic muscles innervated by the cranial nerve VII (facial nerve). Two masticatory muscles (masseter, temporalis) that are supplied by the motoric portion of the cranial nerve V3 (mandibular nerve) also contribute to the contour of the face...

Coronectomy is the intentional partial removal of a tooth. Thereby the crown of the tooth is removed and the roots are left in place. Compared to the complete operative removal of a wisdom tooth, the incidence of inferior alveolar nerve injury (IANI) is lower. The aim of this study is a survey on the use and acceptance of wisdom tooth coronectomy in Switzerland. An anonymous questionnaire was sent to 266 dentists specialized in oral surgery or maxillofacial surgeons; 58.3% of the questionnaires were returned and could be assessed...

This manuscript provides an overview of therapeutic options for the problem of bleeding in a dentist’s office. Bleeding after tooth extraction is a very common finding in dental medicine and persistent blood in the mouth is obviously uncomfortable and sometimes terrifying for the patient. Most bleedings can be stopped simply with compression, in some cases a homeostatic therapy is necessary. For local compression, a swab with tranexamic acid is useful. If local compression is not sufficient, sutures are often an option...

Aim: Intensive application of highly concentrated antimicrobials during scaling and root planing may be hazardous if swallowed in quantity. This study evaluates two dental isolation systems for fluid leakage in conjunction with a sham treatment of scaling and root planing. Materials and methods: Eight volunteers were randomly assigned to wear a conventional rubber dam (RD) and a combined suction and isolation device (IsoLite® system [IL]) alternatively on contralateral maxillary and mandibular quadrants. RD was cut between the canine and the first molar and was fixed on the first molar with a rubber dam clamp and with a tissue adhesive (Histoacryl) on the gingiva...
