Lateral periodontal cysts (LPCs) are rare odontogenic cysts of developmental origin. A 52-year-old man presented with an asymptomatic gingival swelling located between the mandibular left canine and first premolar, both of which were vital. Radiography showed a well-circumscribed radiolucent area and loss of the lamina dura around the tooth socket in contact with the lesion and of the interproximal buccal bone. The lesion was enucleated. The defect was immediately grafted with a 1:1 mixed autologous and heterologous bone graft covered with a collagen membrane. Histology confirmed the diagnosis of LPC. At 12- and 24-month clinical and radiologic follow-up, complete bone and periodontal healing was found, with no sign of recurrence.

Review
This article includes a comprehensive and up-to-date review on the cysts of the oral cavity. Several classifications of odontogenic (OC) and non-odontogenic (non-OC) oral cysts and the surrounding regions have been proposed. We suggest a new critical classification based on an established relationship between anatomical area, histological origin and clinical behavior (frequency, rate of recurrence, malignant potential). Moreover, the differential cytokeratin (CKs) expression of the various cysts is reported as epithelium-specific markers of differential diagnosis. Finally, issues related to differential diagnosis and therapeutic approaches of the cysts included in the two groups are described.

Review
During the past few decades several authors have perpetuated the notion that nearly half of all periapical lesions are radicular cysts. A few studies, based on meticulous serial sectioning of periapical lesions retrieved in toto, have shown that the actual incidence of radicular cyst is only about 15% of all periapical lesions. Equally significant was the discovery in 1980 and recent confirmation that radicular cysts exist in two structurally distinct classes namely, those containing cavities completely enclosed in epithelial lining (periapical true cysts) and those containing epithelium-lined cavities that are open to the root canals (periapical pocket cysts). From a clinical point of view a periapical pocket cyst may heal after conventional root canal therapy whereas an apical true cyst is less likely to be resolved without surgical intervention.

Fusion is a developmental anomaly of dental hard tissues. Most cases occur in the anterior region of both the primary and permanent dentitions. Occasionally, fusion of permanent and supernumerary teeth may occur in the maxillary anterior region; however, a supernumerary tooth fused with a premolar is a rare case. Developmental lateral periodontal cyst is also an uncommon developmental odontogenic cyst with no clinical symptoms, and the lesion is often discovered on routine radiographic examination. In the present case, we report the uncommon fusion of teeth and lateral periodontal cyst in a Chinese girl. Using cone beam computed tomography we are able to acquire a better understanding of the complicated root canal morphology of the fused tooth and successfully manage the lateral periodontal cyst.

Immunohistochemical profile of the anti-apoptosis, apoptosis and proliferation markers Bcl-2, caspase-3, p53, and Ki-67 in botryoid odontogenic cysts compared to lateral periodontal cysts and gingival cysts of the adult.
We investigated the differences in growth and rates of recurrence of the botryoid odontogenic cyst (BOC) and the less aggressive lateral periodontal cyst (LPC) and gingival cyst of the adult (GCA). We compared the immunohistochemical expression of selected biomarkers of apoptosis and proliferation and of regulators of their activity. Sections from archival paraffin blocks of 15 BOCs, six GCAs, six LPCs, and three odontogenic keratocysts (OKCs) were processed for immunohistochemical localization of Bcl-2, caspase-3, p53 and Ki-67. Labeled and unlabeled epithelial cells were counted and differences in the mean labeling index (LI) were evaluated statistically. The only significant differences in LI were for the anti-apoptotic marker, Bcl-2; the hierarchy was BOC > OKC > LPC > GCA. In two BOCs, 97% of the cells, and in all OKCs, all of the basal cells were labeled with Bcl-2. Otherwise, cells labeled with Bcl-2, p53 and caspase-3 were scattered among the basal and intermediate epithelial cell layers. Ki-67 labeled almost exclusively basal cells in the BOCs, LPCs and GCAs, and both basal and intermediate layer cells in the OKCs. Our findings suggest that while there was no significant difference in replicative potential of the GCAs, LPCs and BOCs, factors that influence apoptosis may be partially responsible for the more aggressive behavior of BOCs and OKCs.

Review
Palatal radicular groove is a developmental malformation of maxillary incisors, lateral incisors in particular, which often causes periodontal destruction. This paper reports a case of combined periodontal-endodontic lesions induced by palatal radicular groove, which was initially misdiagnosed as a simple periapical cyst. After root canal therapy and periapical cyst curettage, the course of disease was prolonged, resulting in the absence of buccal and maxillary bone plates in the affected tooth area. After the etiology was determined, the affected tooth was extracted and guide bone tissue regeneration was performed at the same time, followed by implantation and restoration at the later stage, leading to clinical cure. The palatal radicular groove is highly occult, and the clinical symptoms are not typical. If the abscess of the maxillary lateral incisor occurs repeatedly, and the abscess of the maxillary lateral incisor has not been cured after periodontal and root canal treatment, cone-beam computed tomographic and periodontal flap surgery should be considered.

BACKGROUND
The lateral periodontal cyst (LPC) is an unusual cyst of odontogenic origin, most frequently encountered in the mandible between the roots of canines and premolars. The most common treatment for LPC is surgical enucleation. This article reports a case of an LPC treated with guided tissue regeneration (GTR) and bone allograft.
METHODS
A 74-year-old woman presented for periodontal examination. Radiographs revealed a cystic lesion with LPC characteristics. After surgical incisions and flap reflection, the cyst was removed and sent for biopsy. Because of the anatomy of the resulting intrabony defect, GTR was considered the ideal treatment.
RESULTS
The biopsy revealed the histologic features of an LPC. Radiographs at 7 months post-treatment indicated bone fill of the initial defect. Although some attachment loss occurred, the reentry demonstrated a high percentage of bone fill of the defect after 7 months.
CONCLUSION
Depending on the anatomy of the defect left after the removal of an LPC, GTR, along with bone grafting, can be a very useful tool for its treatment by reducing the attachment loss observed after simple enucleation of the cyst.
