The aim of this study was to evaluate the prevalence of dry socket at the faculty of dentistry in Sana’a University. Patient and methods: 994 patients attended to the Oral Surgery Clinic in the faculty of Dentistry, Sana'a University, to have their teeth extracted in period from October 1, 2022 to January 19, 2023. 26 patients with dry socket were analyzed who underwent tooth extraction. Results: The percentage of the patients who had a dry socket was 2.6%. The percentage of male to female was 1:1.3. According to age the dry socket was more in age between 18-30 years. Conclusion: The incidence of dry socket was more happened in young adult, female, single tooth in mandible and with patients taking non-steroidal anti-inflammatory drugs before extraction.

Pyogenic granuloma is a non-neoplastic reactive lesion that commonly occurs in gingiva. It is rarely found in extra gingival sites such as tongue, lip, palate and buccal mucosa. Lesions affecting the tongue are rarer and very few cases are reported. Unusual site of such lesions can be a diagnostic challenge. This case report describes an uncommon location of pyogenic granuloma occurring on the lateral border of tongue in a 60 -year-old male patient.

The odontoma is a benign tumor containing all the various component tissues of the teeth. It is the most common odontogenic tumor representing 67% of all odontogenic tumors. Odontomas are considered to be developmental anomalies (hamartomas) rather than true neoplasms. Based on the degree of morphodifferentiation or on the basis of their resemblance to normal teeth, they are divided into compound and complex odontomas. The compound odontoma is composed of multiple, small tooth-like structures. The complex odontoma consists of a conglomerate mass of enamel and dentin, which bears no anatomic resemblance to a tooth. They are usually diagnosed on routine radiological examinations in the second decade of life and are often slow growing and non-aggressive in nature. Here, we report a case of unusually, rare, compound odontoma, located in the left posterior mandible of a 17-year-old male patient.

Melkersson-Rosenthal syndrome (MRS) is defined by the triad of labial edema, peripheral facial paralysis, and plicated tongue. It is a complex entity with clinical polymorphism and unknown etiopathogenesis. A better understanding of the pathophysiological mechanisms would improve the management of these patients, who often present with significant aesthetic damage. We report a rare case of this syndrome with a plicated tongue and sequellar lagophthalmos.

Complexities of root canal system necessitate the use of irrigation along with their activation to achieve complete cleaning. Common methods include sonic and ultrasonic activation of the irrigants. A newer rotary file system, XP-Endofinisher has the advantage of elliptical movement resulting in efficient cleaning. 24 single canalled maxillary anterior teeth were selected and divided into 3 groups, Group 1- XP (n=12), Group 2- PUI (n=12), Group 3 – Endoactivator (n=12). All samples were prepared with Protaper Universal files and irrigated with 5.25% sodium hypochlorite & 17% EDTA. In Group 1- XP-Endofinisher at 800rpm for 1 min; Group 2- i-SuperTip in EMS scaler for 1 min; Group 3- Endoactivator for 1 min. Specimens were filled with Cerafill and then sectioned horizontally with a water-cooled diamond saw at depths of 4, 7 and 10mm to produce 1mm slices. POBS was performed, bond strength in MPa was obtained after dividing the load at failure by the area of the bonded interface. POBS of Cerafill to root dentin of Group 1 was significantly more than that of Group 2 and 3 (p≤0.05) at all three levels. Group 2 was better than 3 at all levels but difference was not significant. In Group 1, POBS was significantly more at 4mm compared to 7mm and 10mm (p≤0.05). Use of XP- Endo Finisher after biomechanical preparation improves the POBS of bioceramic based sealer to root dentin at 4, 7 and 10mm. POBS of sealer after PUI was marginally better than Endoactivator at all levels.

A glandular odontogenic cyst (GOC) is an uncommon jawbone cyst of odontogenic origin with characteristic histological findings of a lined epithelium that contains mucous cells, ciliated cells, and intraepithelial gland-like structures. We herein report a case of GOC arising in the upper left back tooth region in a 31-year-old female patient. An IOPA radiograph revealed a well-defined unilocular radiolucent area extending from the distal aspect of the root of left first molar to the distal aspect of third molar on the same side. The patient was treated by extraction of 26, 27 & 28 followed by enucleation of the cystic lesion. The surgical specimen was histologically examined and diagnosed as a GOC.

Objectives: All studies performed periodontal distraction with interseptal bone cuts but no one performed it without interseptal bone cuts. Therefore the aim of the present study was to evaluate and compare the effect of periodontal distractor with and without interseptal bone cuts on the pulp vitality of the retracted canines. Methods: The sample of the study consisted of 32 canines in 16 female patients (16- 21 years old) requiring extraction of bilateral maxillary first premolars and canine retraction. They were divided into two groups: canine retraction by periodontal distractor with distal interseptal bone cuts (Group I), canine retraction by periodontal distractor without distal interseptal bone cuts (Group II). After bilateral maxillary premolar extraction in both groups inter septal bone cuts was done in group I only. Then the periodontal distractor was cemented and activated twice per day in both groups. An electrical vitality test was evaluated before and after the distraction procedure. Results: None of the teeth reacted negatively to the electrical vitality test that was performed one month after the completion of the distraction procedure. There was no clinical sign of discoloration or pulpal pain in any tooth. Conclusions: Canine retraction was accelerated effectively by periodontal distraction technique either with or without distal interseptal bone cuts. The electrical pulp tester was positive in both groups.
