Bonding system is one of the branches of dental restorative dentistry, and its primary aim is to provide retention of restorations, typically composites, to the natural substance of teeth enamel and dentin. Historically, adhesive dentistry can be traced to 1955 when Dr. Michael Buonocore first demonstrated the bonding of acrylic resin to etched enamel (Buonocore 1955). Since then, adhesive technology has evolved rapidly in the following years. By now, the bonding system has evolved to the seventh generation, from no-etch (first-generation) to total-etch (fourth- and fifth-generation) to self-etch (sixth- and seventh-generation) systems (Freedman and Leinfelder 2002; Kugel and Ferrari 2000). These advances have led to a large number of commercial adhesives, providing great convenience and satisfactory performance in clinical applications Beyth et al. (2007), Breschi et al. (2010).
Strategy 5: Deliver world-class customer service

Conversely, we all know that the relief of pain and a comfortable, functional and aesthetic result do not necessarily indicate long-term treatment quality. If you are reading this, presumably you know at least a little more about dentistry than the average man in the street – imagine then you have just undergone root canal treatment. How do you know if it is any good or not? The tooth may look and feel fine, but without access to post-operative radiographs how can you be sure that that the canal has been correctly shaped and properly obturated? You cannot, and if you cannot, then imagine the difficulty an average patient would have in making such an assessment. The same can be said for just about every type of treatment we provide. How can a patient know if all subgingival calculus has been removed, or all the caries has been removed from a cavity? How can he or she even know if a restoration was required in the first place?
Benign Oral and Dental Disease

Injury to the front teeth is especially common in, but not limited to, childhood. If a permanent incisor is avulsed then reimplantation as soon as possible is advisable. The tooth can be stored in a suitable medium such as milk pending reimplantation. If the deciduous tooth is avulsed then this should not be reimplanted. Fractures of the crown of the tooth should be attended to by a dentist as quickly as possible. If the fractured fragment can be identified it can be reattached to the tooth rather than a restorative filling material being placed. If there is any soft-tissue injury and a missing tooth fragment, the wound should be explored for the fragment before closure. Dental trauma can be a presentation of non-accidental injury in a child and this, together with the pattern of soft-tissue injury and other points from the history should remind the practitioner to consider this aetiology.

A 67-year-old woman sought physiotherapy service reporting pain, dysfunction, and sensory loss in the left jaw. The patient reported that the condition started 8 months before the first consultation as a sharp and throbbing headache on the left side, which forced her to interrupt her rest day from work. On the next day, the pain expanded to the lower teeth and the patient consulted a dentist, who diagnosed her with a periodontal problem. After four failed anesthesia procedures attempts, the dentist performed a root canal treatment without relief. On the following day, the patient noticed the presence of skin blisters on the left chin, with features of impetiginized lesions. A home-visiting physician diagnosed her with trigeminal PHN and prescribed oral Acyclovir, vitamin B, and Ibuprofen 4 times a day. After two days without improvement of the symptoms, the patient sought medical attention in a private hospital of Rosario (Argentina) where she was hospitalized for four days for medical examinations and treated with intravenous Acyclovir, Ciprofloxacin, Clindamycin, and Tramadol. After hospitalization, the patient continued taking Acyclovir 800 mg and Tramadol 25 mg orally 4 times daily for a month. After two months, she was instructed to stop the intake of Acyclovir and to continue the treatment with 40 drops of Tramadol daily. During the next month, the doctor allowed her to reduce the dose by one drop according to the severity of the symptoms. During these two months, the pain reached its higher intensity, and the patient spent most of her time in the bedroom.
Cell homing strategy as a promising approach to the vitality of pulp-dentin complexes in endodontic therapy: focus on potential biomaterials

Regenerative dentistry has evolved significantly, which tries to rebuild the tooth and recover its functionality. Engineering a proper milieu that enables angio/vasculogenesis and innervation is difficult due to the specific anatomic restrictions of the tooth anatomy [24]. Tissue engineering techniques based on cells have shown significant promise in accomplishing this objective. Scaffold-based or scaffold-free techniques are the most common biomedical ways to generate a regenerative microenvironment. Scaffold-based tissue creation depends primarily on using biomaterials to build a basic structure that supports cells throughout the tissue formation procedure. A conventional three-dimensional structure with interlinked holes, a hydrogel with cells implanted, or a mix of these might be used as the scaffold [25,26]. Cell sheets, spheroids, or tissue strands are used as essential components in the scaffold-free technique, a bottom-up method. The ability of these building pieces to produce a suitable extracellular matrix and combine it into bigger tissue constructions is critical to the success of this method. For endodontic therapy, both the scaffold-based and scaffold-free systems are necessary as complementary approaches [27]. A hybrid synergetic technique, in which multicellular building blocks are coupled with sturdy three-dimensional scaffolds, maybe the best way to avoid some of the critical disadvantages of existing pulp regeneration methods while enhancing their benefits [28].
Antibiotic utilization in emergency dental care in Stockholm 2016: a cross sectional study

During the study period we collected 13 questionnaires from treating dentists at both clinics. Most dentists were female (69%, n = 9), with 31% male (n = 4). The dentists’ clinical experience varied from 4 to 40 years with a mean of 17 years. Most of the dentists (77%, n = 10) were working in emergency dental care, 15% (n = 2) were commonly working as general dentists, and 8% (n = 1) was a specialized dentist. The dentists were asked if the national recommendations for antibiotic prophylaxis prescription prior to treatment were clear. Eighty-three percent of the dentists (n = 11) answered ‘yes’ and 16% (n = 2) replied ‘no’. Moreover, when asked whether the national recommendations for antibiotic treatment of odontogenic infections, 31% of dentists (n = 4) prescribed antibiotics for patients normally not requiring antibiotics (such as patient travel, patient safety, follow-up not possible). One-third of the dentists (n = 4) admitted that they occasionally prescribed antibiotics due to time limitation or patient request (Table 3).
