The aim of this study is to determine the incidence of obliterated osteomeatal complex (OMC) due to the presence of anatomic variants.

Retrospective Study.

In this retrospective study, a total of 71 patients, 34 males and 37 females, aged 35-65 years were included in the study. Cone beam computed tomography (CBCT) scans of patients were assessed to identify the status of the OMC in the presence of anatomic variants and their incidence was recorded. The radiological assessment of the anatomical variants was made by viewing the coronal sections of the scans. The variants observed were deviated nasal septum, uncinate process), agger nasi, Haller cells, middle turbinate variants, enlarged bulla, accessory ostium, and maxillary sinus abnormalities). Ostium patency was evaluated in the coronal section of each sinus and classified as "patent" or "obstructed." The most common variants observed were then correlated with the patency of the ostium.

Chi square test was performed to assess the association between the ostium before sinus floor elevation procedures. The pre and postsurgical treatment plans and regimes can be modified according to anticipated postsurgical sequelae, thereby avoiding postsurgical complications and enhancing the success of the graft procedure.

This study assessed the effect of postetch cleansing on the surface microstructure, surface topography, and microshear bond strength (μSBS) of lithium disilicate and the resin cement.

analytical study.

Fifteen discs (10 mm diameter and 2 mm thickness) were fabricated from highly translucent lithium disilicate IPS Emax 2 ceramic (Ivoclar Vivadent, Schaan, Liechtenstein). Four resin cement (RelyX Ultimate, 3M ESPE) cylinders (0.9 mm diameter and 4 mm high) were placed on each ceramic disc (total

= 60). The samples were divided into three groups based on the surface treatment of the ceramic discs (20 resin cement cylinders on 5 discs in each group). Group I (HF) (control) etched with 9.6% HF with no postetch cleansing, Group II (HFP) etched with 9.6% HF for 20 s followed by rinsing with water and postetching cleansing with 37% phosphoric acid, and Group III (HFPU) etched with 9.6% HF followed by active application of 37% phosphoric acid followed by postetch cleansing in ultrasonic bath for 5 min. μSBS g was done.

Peri implant diseases lead to pathological changes in the peri implant tissues and loss of osseointegration. The purpose of this analysis is to evaluate the effect of various lasers and photodynamic therapy (PDT) on peri implant diseases compared to conventional procedures.

This meta analysis was conducted as per the Preferred Reporting Items for Systematic Reviews and Meta Analyses guidelines.

A systematic search of the electronic databases such as PubMed, ICTRP, CT.gov, Embase, and Cochrane Library was done additional to manual search of peer review article on peri-implant diseases. Eleven randomized control clinical trials were included in which laser therapy and PDT were used as an interventional procedure.

Review Manager 5.03 (RevMan, Nordic Cochrane Center, Copenhagen, Denmark), and random effects model were used to assess mean difference (MD). Bivariate differential mean statistic was used in intergroup estimate with 95% confidence interval (CI). I2 test statistics was applied for heterogenity and

< 0.05 was considered significant statistically. The literature search yielded a total of 113 articles among which 11 articles were included for quantitative analysis. The selected outcome PD reported MD -0.01 with 95% CI (-0.13, 0.16),

= 0.84, and CAL reported MD -0.09 with 95% CI (-0.32, 0.14),

= 0.45, respectively.

Laser treatment as an adjunctive therapy or monotherapy in peri implantitis does not show any superior effects than conventional measures as per evidence. However, cases with peri implant mucositis have shown far more promising results with laser therapy compared to peri implantitis.

To evaluate different methods, techniques, and concepts documented in the literature to assess iris positioning accurately to the related dimensions needed to effectuate maxillofacial rehabilitation of ocular prosthesis.

This systematic review was conducted as per the PRISMA guidelines which is the most opted reporting protocol.

Two electronic databases PubMed and Cochrane Library) were searched for manuscripts published from 1969 till September 30, 2019. selleck chemicals llc An electronic search (of peer review restricted to English language dental literature was conducted to identify the relevant scientific article on iris positioning in maxillofacial prostheses. Two observers independently read the abstracts and selected 17 full text articles fulfilling the inclusion criteria.

No meta-analysis was conducted due to heterogeneity of data obtained.

All the 17 documented articles related to determination of the iris positioning to perform maxillofacial prosthetic rehabilitation depicting the use of a strip of plastic template, a Boley's gauge, a millimeter ruler, a pupillometer, window light, an ocular locator with fixed caliper, inverted anatomic tracings, a transparent graph grid were reviewed systematically.

Currently, there is no evidence in the form of a systematic review of the available literature discussing the best technique available for perfectly matching the iris positioning. However, the latest techniques making use of digital technology such as digital photography, is believed to be more precise for iris positioning in the ocular prosthesis.

The aim of this meta analysis was to evaluate the influence of the processing method on the marginal and internal gaps of lithium disilicate inlays/onlays.

A systematic literature review was conducted using the PubMed/Medline, Embase, Scopus, and Cochrane Library databases. This review was registered on the PROSPERO platform.

The studies were selected according to the marginal and internal gaps of two different fabrication methods for lithium disilicate (milled and pressed).

The meta analysis was performed based on the Mantel-Haenszel and inverse variance methods, using the random effects model and a 95% confidence interval.

From all databases, 127 studies were identified. Four in vitro studies were included in the qualitative analysis and three in the meta analysis. Moreover, 197 restorations were evaluated (103 pressed and 94 milled). During the evaluation of only the internal gap, there was a statistically significant difference favoring the pressed technique (

= 0.002). There was no statistically significant difference in the analyses of the marginal gap (

= 0.530) and the total gap (

= 0.450).

Both the techniques provided acceptable marginal and total gaps, although the pressed technique revealed a more favorable internal adaptation than the milled onlays/inlays.

We report a case of renal cholesteatoma in a 4-year-old male child who was referred to us as a case of multiple renal calculi with hydronephrosis. We also discuss his management with a review of relevant literature.Transverse testicular ectopia (TTE) is an uncommon anatomical abnormality where both the gonads migrate toward the same hemiscrotum. Embryologically, several theories regarding the origin of TTE have been suggested including adhesion and fusion of developing Wolffian canals, aberrant gubernaculum, testicular adhesions, defective formation of the internal inguinal ring, and traction on the testis by persistent Mullerian structures. To date, about 100 cases of TTE have been reported in the literature. Herein, we report five cases of TTE operated in the Department of Paediatric Surgery, Sardar Patel Medical College, Bikaner, over a period of 5 years. All cases were in the age group of 3 months to 4 years, out of which four were diagnosed preoperatively by clinical examination and ultrasonography (USG). Two of these four cases presented with inguinoscrotal swellings and contralateral undescended testes and other two presented with absence of testes in the scrotum. One case presented with a scrotal abscess which revealed both the testes in the abscess cavity. All five cases were operated upon with herniotomy and transseptal orchidopexy and discharged successfully. TTE, although rare, has a spectrum of presentations and should be kept in mind as a possibility in cases of inguinoscrotal disorders in young age group. A preoperative USG may be helpful in conformation of diagnosis.Arteriovenous malformations (AVMs) of the scrotum are very rare, with only 35 adult cases in the literature. An 8-year-old boy presented with an ulcerated bleeding AVM of the scrotum. The patient was resuscitated and managed conservatively initially. After the control of bleeding, oral propranolol was started. There was a decrease in the size of scrotal and penile swelling, healing of ulcer with total healing by 1 month, and no recurrence of bleeding episode. To the best of our knowledge, this was the first case of pediatric scrotal AVM treated by oral propranolol.Newborn babies presenting with difficulties related to the aerodigestive tract (ADT) are often provisionally diagnosed and managed as having oesophageal atresia +/- tracheo-oesophageal fistula. Continuing difficulties with management and abnormal findings on investigations should lead to the consideration of other congenital anomalies of the ADT, including complete larnygo-tracheo-oesophageal cleft (LTOC). We present two patients who were eventually diagnosed with complete LTOC and care was withdrawn. We discuss the inherent difficulties in reaching this diagnosis and present an algorithm to help manage these rare and challenging situations.Mediastinal pancreatic pseudocyst (MPP) is an infrequent complication of acute pancreatitis in children. A contrast-enhanced computed tomogram (CECT) of the chest and abdomen can aid in diagnosing pleural effusion and MPP. We describe a child with MPP in whom a transcutaneous computed tomogram-guided external drainage was curative. The case is being presented, and the relevant literature is highlighted in view of rarity of this entity.Anorectal malformations (ARMs) have coexisting congenital anomalies. These can affect the overall prognosis. Anomalous craniofacial associations are less common. Recently, we managed two patients of ARM associated with unilateral microphthalmia, without any other major systemic anomalies. This was found to be a rare association on extensive literature search.
