This case report describes the long-term follow-up of a patient with localized aggressive periodontitis over a 30-year period. A 16-year-old woman was referred for periodontal assessment after starting orthodontic treatment. The patient was treated initially by combined nonsurgical and antimicrobial therapy, and autotransplantation of maxillary third molars in place of maxillary first molars, followed by a regular supportive periodontal treatment program. This challenging case demonstrated that elimination of putative bacterial pathogens and long-term supportive periodontal treatments provide an effective treatment modality for localized aggressive periodontitis...

Ihsène Taihi, Loredana Radoi
Chronic non-suppurative osteomyelitis (CNSO) is a chronic bone disease and may be associated with a reparative periosteum entity called proliferative periostitis (PP). This condition rarely affects the maxillofacial region. Mandibular cases were already described for an infectious dental cause, often with an "onion skin" radiographic aspect, but some rare reported cases showed no obvious etiology. They represent a challenge for diagnosis because of possible misdiagnosis leading to unsuccessful or inappropriate treatment attempts...

According to the Fifth German Oral Health Study, the caries experience in the German population is declining sharply. The number of teeth still present at an advanced age has also increased significantly in recent decades. This shows a clear trend towards long-term tooth preservation - possibly with fixed dental prostheses - which is further supported by the possibility to place implants to increase the number of abutments. The pronounced decline in caries experience has given Germany a leading international position in terms of dental health...

This case report presents long-term results following horizontal root fracture of both maxillary central incisors in a 19-year-old woman with aggressive periodontitis. Due to extensive marginal bone loss and the close proximity of the fracture lines to the bottoms of the periodontal pockets, the prognosis of both teeth was uncertain at the time of the accident. Nevertheless, a conservative treatment strategy consisting of splinting and nonsurgical periodontal therapy was initiated. Follow-up at 12 years after the start of treatment revealed a stable situation from clinical and radiologic perspectives...

In chronic periodontitis and peri-implantitis, cells of the innate and adaptive immune systems are involved directly in the lesions within the tissues of the patient. Absence of a periodontal ligament around implants does not prevent a biologic process similar to that of periodontitis from affecting osseointegration. Our first focus is on factors in the biology of individuals that are responsible for the susceptibility of such individuals to chronic periodontitis and to peri-implantitis. Genetic factors are of significant importance in susceptibility to these diseases...
