Residual cysts are uncommon odontogenic cyst, which occurs as a result of incomplete surgical removal of any odontogenic cyst. It is a type of inflammatory odontogenic cyst, in which the tooth is extracted with a periapical pathological area left behind in the bone that leads to the formation of a residual cyst. They are usually asymptomatic in nature and its clinical, radiographic and histopathological features are similar to that of radicular cyst.

2019We designed a V-shaped plate to involve both lines of osteosynthesis within a single plate. Implant dimensions. An internal locking mechanism is incorporated to accentuate stability across the fracture line.The V plate can be positioned in four different directions:0◦(∨), 90◦(<), 180◦(∧), and 270◦(>).We have compared this implant with standard mini-plates that are commonly used for the treatment of anterior mandibular fracture using Finite Element Analysis.

Cyst is defined as pathological cavity having fluid , semifluid or gaseous contents and
which is not created by accumulation of pus .The Dentigerous cyst initially is always
associated with the crown of an impacted, embedded, or unerupted tooth.It develops around
the crown of an unerupted tooth by the expansion of the follicle when fluid collects
between the reduced enamel epithelium. Such cyst remain initially completely
asymptomatic unless when infected and can be discovered only on routine radiographic
examination. It accounts more than 24%of jaw cysts, usually develops around crown of
mandibular third molar, maxillary canine, followed by mandibular premolars, rarely
involve supernumerary teeth and central incisors .A case of cyst in a 23 year old female,

Development of a new v shaped locking plate and screw which can be effectively used for management of mandible fracture was developed. FEM study was done to evaluate plate design to handle stress and strain.

The orbital floor is a bone structure frequently involved in orbital fractures. Various methods have been documented to approach the orbital floor and infraorbital rim. Traditionally, transcutaneous approaches like infraorbital, subciliary, and subtarsal have been employed to access the orbital floor and infraorbital rim. A significant amount of complications including a visible, prominent scar, eyelid abnormalities like ectropion, lower lid retraction, and increased scleral show result from these transcutaneous approaches. To overcome these complications, the transconjunctival approach has been preferred recently. However, the transconjunctival approach has been associated with rare complications like entropion, synechia, or trichiasis. In the present article, we report a case of orbital floor fracture treated using a retroseptal transconjunctival approach. We intend to evaluate the aesthetic outcome of a case of orbital floor fracture treated using a retroseptal transconjunctival approach.

A variety of approaches have been documented in the literature for accessing the infraorbital rim and orbital floor in cases of fractures involving orbitozygomatic maxillary complex fractures. Various transcutaneous approaches like infraorbital, subtarsal, and subciliary approaches have been employed traditionally to access these regions. However, significant postoperative complications are associated with these approaches. The transconjunctival approach to access the infraorbital rim and orbital floor has recently been re-evaluated. We present a case of a patient with a zygomaticomaxillary complex fracture in which the infraorbital rim was fixed using a transconjunctival retroseptal approach

Application of v shaped plate in mandible fracture management.

Calcifying odontogenic cyst is a rare odontogenic cyst. It was described by Gorlin in 1962 and is also called as Gorlin’s cyst. Ghost cells in the epithelium are the hallmark of Gorlin’s cyst. A 25 year old male patient complained of a painless swelling in his lower anterior teeth region which was present for the past 3 years. It was slow growing with absence of infiltration, soft in its center and bony hard in its periphery, radiograph showing multilocular radiolucency, with associated root resorption, tooth displacement. Histopathological examination revealed a cystic lesion, lined by odontogenic epithelium and amorphous eosinophilic round or oval structures suggestive of ghost cells were seen within the epithelium. A long standing multilocular radiolucent lesion in the mandible crossing the midline with clinical features imitating anameloblastoma and odontogenic keratocyst was later diagnosed as a Gorlin’s cyst with histological evidence.

Pain control through the truncal block of the inferior alveolar nerve is one of the locoregional anesthetic techniques most widely used in oral surgery, affording comfort and safety for both the patient and operator when used correctly. Aim: To compare the anesthetic efficacy of both 4% articaine and 2% lignocaine with epinephrine in the truncal block of the inferior alveolar nerve during surgical removal of the impacted mandibular third molars. Materials and Methods: A randomized, double‑blind, clinical trial was conducted of 360 patients programmed for the surgical extraction of symmetrical lower third molars in the context of the Master of Oral Surgery and Implantology (Saveetha Dental College, Saveetha University, Chennai, India). Following the obtainment of informed consent, two operators performedsurgery on an extemporaneous basis, using as local anesthetic 4% articaine or 2% lignocaine, with the same concentration of a vasoconstrictor (epinephrine 1:100,000). The study variables for each anesthetic were: Latency (time to action) and duration of anesthetic effect, the need of reanesthetizing the surgical zone, and intraoperative pain intensity measured objectively using the Visual Analog Scale (VAS) and Faces Pain Scale (FPS). Data were analyzed using the Independent t‑test and Chi‑square test. Results: A statistically significant difference (P < 0.05) was observed in the mean duration of the anesthetic effect (216.98 minutes for 4% articaine vs. 158.49 minutes for 2% lignocaine). The amount of anesthetic solution and the need to reanesthetize the surgical field showed clinical differences in favor of articaine, although a statistically significant difference was not seen. The VAS and FPS scores were statistically significant when compared with 2% lignocaine (P < 0.05). Conclusion: We conclude that 4% articaine has better anesthetic efficacy as compared to 2% lignocaine. This can be explained based on its different chemical structure, liposolubility, increased protein‑binding ability, diffusion in soft tissue, and increased pulpal anesthesia

Vertical and anterioposterior maxillary excesses can be treated with a combination of orthopaedic functional appliances, orthodontics
and surgery. Treatment varies according to the age, patient reports for treatment. In patients who are treated with either of the above
mentioned treatment modalities, if they require prosthetic replacement on a later date, especially of anterior teeth, prosthetic treatment
alone does not give an aesthetic outcome. A partially edentulous, elderly patient with underlying skeletal discrepancy (Class II Skeletal
deformity) in relation to 12,11,21,22 was treated with a combination of orthognathic surgery and prosthetic rehabilltation. An orthognathic
surgery (leforte I osteotomy) was performed to manage vertical maxillary excess, class II skeletal pattern of maxilla and increased lower third
facial height. Dental compensations in the mandibular arch were decompensated surgically with lower subapical osteotomy. Prosthetic
restorations of missing anterior teeth were done later, such that facial and dental aesthetics. The records showed that the results were
stable 12 months after prosthognathic (prosthodontic and orthognathic) treatment. A team approach enabled the female patient in her fifth
decade of life, to receive better function, aesthetics and increased quality of life. Doing prosthetic restorations in patients with underlying
skeletal discrepancies may become a challenge , which should be achieved without compromising on final outcome, with a calculated risk
benefit ratio.

Abstract
Background
Mandible is the only mobile facial jaw bone and it aides in various functions such as phonation and mastication. Therefore, management of mandible fracture becomes inevitable due to its functional and anatomical importance. Fracture fixation methods and techniques have steadily evolved with various osteosynthesis systems. In this article, we discuss the management of mandible fracture using a newly designed two-dimensional (2D) hybrid V-shaped plate.

Purpose
In this paper, we have evaluated the efficacy of the newly developed 2D V-shaped locking plate in the management of mandibular fractures.

Method
We have assessed 12 cases of different mandibular fractures ranging from symphysis, parasymphysis, angle and subcondylar region. Treatment outcome was assessed both clinically and radiologically at regular intervals with various intraoperative and postoperative parameters.

Result
Results of this study suggest that fixation of mandible fracture with the 2D hybrid V-shaped plate facilitates anatomic reduction and functional stability and carries a low morbidity and infection rate.

Conclusion
The 2D anatomic hybrid V-shaped plate can be a suitable alternative to conventional miniplate and 3D plates as it offers satisfactory anatomic reduction and functional stability. Positioning the plate in relation to the mental nerve and plate adaptation along the angle region are much easier.
