Pathologic changes in the pericoronal tissues of unerupted third molars.

OBJECTIVE: The purpose of this study was to determine whether the incidence of pathologic conditions affecting the pericoronal tissue of unerupted third molars justifies their routine removal. METHOD AND MATERIALS: The pericoronal tissue associated with completely unerupted third molars was submitted for histologic examination after surgical tooth removal was performed in 37 males and 55 females, aged 13 to 63 years. The 104 unerupted third molars comprised 68 mandibular third molars (65.38%) and 36 maxillary third molars (34.62%). RESULTS: The incidence of normal tissue of a dental follicle was 41.35%, and the incidence of pathologic tissue was 58.65% (dentigerous cyst, 50.96%; chronic nonspecific inflammatory tissue, 4.81%; odontogenic keratocyst, 1.92%; ameloblastoma, 0.96%). The incidence of pathologic conditions was higher than that of normal conditions in all third molar positions. In younger patients, normal tissue was more commonly found, but in patients older than 20 years, the incidence of pathologic tissue was higher than the incidence of normal tissue. CONCLUSION: Unerupted third molars should be removed before pathologic changes can occur in their pericoronal tissues. This justifies routine removal of unerupted third molars from patients older than 20 years.

Long-term follow-up of peripheral ossifying fibroma: report of three cases.

Peripheral ossifying fibroma is a non-neoplastic enlargement of the gingiva that is classified as a reactive hyperplastic inflammatory lesion. It is possible to misdiagnose peripheral ossifying fibroma as pyogenic granuloma, peripheral giant cell granuloma, or odontogenic tumors. Therefore, histopathological examination is essential for an accurate diagnosis of such lesions. Differential diagnosis is important, because peripheral ossifying fibroma has a tendency to recur. This article describes three cases of peripheral ossifying fibroma, which were followed for 4 years without any sign of recurrence. By presenting these cases, we emphasize the importance of proper excision and aggressive curettage of the adjacent tissues for prevention of recurrence.

The use of chemotherapeutic agents in localized periodontal pockets.

Gingival diseases are the most widely dispersed diseases in the United States. In some patients, periodontal disease appears in a generalized form, but more often it appears in localized areas. Furthermore, after treatment with scaling and root planing in generalized cases, the disease is often reduced to a few local areas in the patient's mouth. Because periodontitis is a bacterial infection with known pathogenic microorganisms, the local delivery of antimicrobial agents has been considered to be a possible solution for treating and controlling localized forms of periodontal disease. Three local chemotherapeutic agents are reviewed in this paper: tetracycline fiber, doxycycline gel, and chlorhexidine chip. With the advancement of local drug delivery systems, restorative dentists, periodontists, and their patients have new alternatives for the treatment of periodontal disease. Local chemotherapeutic agents offer an additional mode of therapy and should be used on a case-by-case basis, not necessarily as an initial treatment.

Development and laboratory evaluation of a new toothbrush with a novel brush head design.

Despite many developments in manual toothbrush design, plaque removal at the back of the mouth and at approximal surfaces remains inadequate, yet it is at these sites in particular that plaque accumulates and leads to the development of gingival disease. Improved oral hygiene can be achieved by better brushing technique and by increasing brushing time, but a change in behavior patterns is almost impossible to achieve for the majority of individuals. What is required is a brush head design that maximizes plaque removal, regardless of how the user brushes. As a result of a detailed investigation into the action of bistles during brushing, the Oral-B CrossAction toothbrush has been developed. It incorporates bristles angled at 16 degrees in a unique CrissCross design arranged along the horizontal axis of the toothbrush. Laboratory studies have demonstrated that this development significantly enhances interproximal penetration and cleaning effectiveness when compared with an identical brush head with vertical rather than angled bristles. Laboratory comparisons with more than 80 leading manual toothbrushes from around the world demonstrate a consistent, significant advantage for the new CrossAction toothbrush, both with respect to interproximal penetration and cleaning effectiveness. These results suggest that the CrossAction toothbrush has the potential to remove greater amounts of plaque, especially from the approximal surfaces, than conventional toothbrushes incorporating vertical bristles or more traditional tuft designs.

Periodontal plastic surgical technique for gingival fenestration closure.

Gingival fenestration is an opening through oral keratinized tissue, usually unattached, that is observed in thin gingiva with usually thick subgingival calculus deposits. This lesion is seen infrequently but may be more common than has been reported; lack of symptoms may inhibit patient awareness. Because surgical correction usually is not required, there are very few reports in the literature concerning this lesion. The following report describes a case of gingival fenestration and surgical treatment with a connective tissue/periosteal graft.

Acellular dermal matrix allograft in the treatment of mucogingival defects in children: illustrative case report.

Mucogingival defects can occur in children and are of particular concern when orthodontic treatment is indicated. The rationale for surgical intervention is predicated on the need to repair the mucogingival defect and to establish adequate thickness of attached gingiva. The free gingival graft, usually obtained from the hard palate, is often used to increase the amount of attached gingiva. The prospect of a second surgical site, and its inherent risks and complications, which may include pain, discomfort, and bleeding, is especially undesirable in children. Important to consider is the possibility that a child may not have adequate tissue thickness at the donor site. A case report is presented utilizing the alternative soft tissue graft, Alloderm, to correct a mucogingival defect prior to orthodontic treatment. Adhering to the free gingival autograft technique, an acellular dermal matrix allograft was utilized at the graft site. The patient revealed good post-operative healing, tissue vascularization, and a healthy zone of attached gingiva at the six month follow up visit. Comparable results to the conventional autograft were obtained with less surgical time, surgical sites, and discomfort to the patient.

[Immediate post-extraction implant in infected site. An eight-year clinical and radiographic control].

The use of immediate post-extraction implants presents several advantages in term of reduction of surgical steps and time required to conclude the therapy. Particularly important is the possibility to minimize the bone loss that otherwise would occur in the physiologic healing of the alveolus. Many authors agree that an infected site is one of the main contraindications to use post-extraction implants. In spite of this, favourable results have been reported also in these conditions. In this study, an immediate post-extraction implant has been placed to substitute the maxillary left second premolar, extracted due to vertical root fracture. Suppuration with fistula in the vestibule was present. The residual wide bone defect at the end of the debridement of the surgical socket has made it necessary a regenerative procedure by means of e-PTFE membrane, at the same time of implant insertion. After 9 month-healing the membrane has been removed and the implant exposed to perform the prosthetic procedures. The clinical and radiographic control after 8 years prove that infection in the surgical site has not compromised the final success, even in the long-term observation, suggesting the need to re-evaluate the contraindications conventionally reported.

Connective tissue graft: a classification for incision design from the palatal site and clinical case reports.

A classification system for connective tissue graft incisions is proposed. It categorizes the design of the palatal incision into three classes. In addition to the basic classification, two subclasses are mentioned in this article. Additional descriptions are included to further define the incision design. The use of such a classification should assist future communication among clinicians and researchers. This article presents representative clinical cases to aid the clinician in applying the classification for incision design from the palatal site.

Gingival prostheses--a review.

Gingival replacement is often a component of comprehensive prosthodontics. Gingival prostheses may be fixed or removable and may be made from acrylics, composite resins, silicones or porcelain-based materials. Undercuts or dental attachments are used to secure removable prostheses, which are esthetically pleasing and easy to maintain. This paper describes several clinical situations in which gingival prostheses were used effectively.

Gingival fibrous nodule--anomaly or pathology?

Three cases of a relatively common but rarely reported intraoral condition are described. Clinically, this condition appears as an asymptomatic, tumor-like nodule or nodules along the labial anterior mucogingival line and are characterized histologically by an accumulation of dense collagenous tissue. This entity represents a developmental condition and should be distinguished from reactive and neoplastic lesions. No treatment is necessary.
