A radiographic survey of periapical jawbone lesions.

A radiographic survey of the jawbone adjacent to the teeth revealed a high incidence of bone pathosis in 889 randomly chosen patients. Jaw lesions, nearly all inflammatory, were present in every second person. Bone-destructive inflammatory processes (rarefying osteitis) were the most frequently encountered lesions, occurring in both the maxilla and the mandible. Bone-appositioning inflammatory processes (condensing osteitis), on the other hand, appeared mostly in the mandible, very often involving the first molar, thus indicating the differing biologic behavior of the two jawbones. Other bony manifestations in the mandible, such as enostosis and periapical cemental dysplasia, although relatively rare, also formed part of the picture. In light of the absence of related symptoms, the clinical significance of these widely prevalent periapical lesions has to be reconsidered.

Bacteriologic evaluation of ultrasonic root canal instrumentation.

The antibacterial effect of ultrasonic instrumentation in the treatment of infected root canals was clinically evaluated. Sodium hypochlorite solution (0.5%) was used as an irrigant, but no antibacterial intracanal dressing was used between the appointments. The ultrasonic technique eliminated the bacteria from the canals more efficiently than hand instrumentation alone. Even though ultrasonication definitely improves the procedure of root canal disinfection, the use of an antibacterial dressing between appointments is necessary to achieve as complete a reduction in bacterial levels as possible.

Use of general anesthesia in dental care of the child with sickle cell anemia. A case report.

This article reviews the clinical manifestations of sickle cell anemia and describes the dental management, with the use of general anesthesia, of a child affected by the disease and exhibiting some of its complications. The discussion stresses the vital importance of awareness of the possible complications of sickle cell anemia and sickle cell trait in the safe and successful management of patients requiring dental care that includes the use of general anesthesia.

Cutaneous sinus tracts of dental etiology.

Intermittently draining cutaneous sinus tracts in the area of the face and neck may be caused by chronic dental infection. Diagnosis of the cause may be challenging but is the key to successful therapy. Two cases of these uncommon lesions are presented; one involved a mandibular molar and the other a mandibular incisor. Nonsurgical endodontic treatment was performed. Healing was rapid and uneventful.

Apical closure of mature molar roots with the use of calcium hydroxide.

Calcium hydroxide may induce apical root closure in affected mature teeth as well as in immature teeth. Once an apical hard tissue barrier is formed, a permanent root canal filling can be safely condensed. Two cases are described in which calcium hydroxide induced apical root closure in mature molar teeth where the apical constriction was lost because of chronic inflammatory process.

Cervical necrotizing fasciitis of odontogenic origin.

Necrotizing fasciitis is a severe soft tissue infection caused by both aerobic and anaerobic bacteria and is characterized by a rapid extension along fascial planes and by necrosis of soft tissues. The disease rarely occurs in the head and neck. Three cases of necrotizing fasciitis of the neck after a dental infection are presented. The difficulty in diagnosing the early stage of this condition in relation to other soft tissue infections of odontogenic origin in the neck is discussed. The importance of an early diagnosis followed by an appropriate combination of medical, surgical, and dental treatment is emphasized.

Oral mucosal soft tissue necrosis caused by superinfection. Report of three cases.

Three patients in whom flap necrosis developed after oral surgeries and antibiotic therapies were studied microbiologically by routine aerobic and anaerobic methods. In all cases the bacteria Enterobacter cloacae, Klebsiella oxytoca, Escherichia coli, and coagulase-negative penicillinase-producing staphylococci were resistant to the antibiotics used. These bacteria are frequent microorganisms of superinfection and were not found after the necrotic tissues had repaired.

Prolonged infection of the floor of the mouth in hyperimmunoglobulinemia E (Buckley's syndrome). Report of a case.

A case of prolonged infection of the floor of the mouth with a generalized eczematous dermatitis in a 13-year-old boy is described. Immunologic examination revealed markedly elevated serum concentration of immunoglobulin E (IgE) and impaired neutrophil chemotaxis. The disorder was diagnosed as the hyperimmunoglobulinemia E (Buckley's syndrome) and was successfully treated with high doses of antibiotics and human immunoglobulin.

Osteomyelitis of the mandible in Tehran, Iran. Analysis of 88 cases.

This study involved 88 cases of different types of osteomyelitis of the mandible. Sixty-nine patients had osteomyelitis after trauma, eight patients after radiotherapy, six after dental infection, and six had other causes. Thirty-three patients had septicemic infection. Multiple types of aerobic and nonaerobic microorganisms were isolated from the infection sites. Types of treatment and their results are discussed.

Conventional and surgical endodontic retreatment of a maxillary first molar: unusual anatomy.

The prognosis for endodontic treatment in teeth exhibiting a complex anatomy is unfavorable if clinicians fail to recognize extra root canals. This case demonstrates the presence of a second canal in the disto-buccal root of a maxillary right first molar. Conventional retreatment followed by endodontic surgery was performed and a 1-year postoperative radiograph shows apparent periapical healing.

Intentional replantation: a case report.

Nonsurgical retreatment and surgical endodontics are not always viable solutions to endodontic disease. Access for retreatment may be limited by posts. Surgical endodontics may be limited by anatomical features including bone thickness and nerve and sinus proximity. Anatomical limitations and complex restorations may prevent implant placement. Intentional replantation is considered by many as a procedure of last resort when nonsurgical or surgical endodontics is contra-indicated. The treatment described demonstrates intentional replantation as a procedure to be considered when endodontic procedures or a dental implant are not possible.
