Introduction: Oral mucosa can be affected by a variety of soft tissue lesions and conditions. Benign as well as malignant lesions of oral cavity are common. Squamous cell carcinoma is one of the commonest malignancies. The present retrospective study was undertaken to study the prevalence of various oral mucosal lesions in a tertiary care dental hospital of Kathmandu.
Methods: This retrospective study was carried out in the Department of Oral and Maxillofacial Pathology at Kantipur Dental College and Teaching hospital from January 2015 to January 2017. The study included biopsy specimen from the oral cavity. The parameters included in the study were age, gender, site of the lesion and histopathological diagnosis. The data collected was statistically analyzed.
Results: A total of 111 biopsy cases were included in the present study. Out of which, there were 16 (14.4%) cases of non-neoplastic and 16 (14.4%) cases of benign pathology. The oral cavity lesions were commonly seen in age range between 6-74 years where males 59 (53.2%) were mostly affected. The most common site for oral lesion was buccal mucosa 23 (20.7%) and anterior gingiva 23 (20.7%). Total 15 (13.5%) cases of oral squamous cell carcinoma were seen as the predominant malignancy affecting in the vestibular region 8 (7.2%).
Conclusions: The present study shows benign as well as the non-neoplastic lesions were more prevalent in oral mucosa with the buccal mucosa and anterior gingiva as the commonest site of occurrence.

Background: Mefakia is a well-known traditional chewing wood used in Ethiopia to cleanse the mouth. Although mefakia is used in parallel with modern toothbrushes to improve oral hygiene, there is a gap in the literature regarding its comparative performance in removing plaque and maintaining good oral hygiene.
Objective: This study aimed to evaluate and compare the oral hygiene status of patients using mefakia and modern toothbrushes at the Holy Bethel Dental Clinic in Addis Ababa, Ethiopia.

Objectives: This double-blind randomised crossover trial aimed to compare the aesthetic outcomes of CAD-CAM manufactured provisional restorations created using cone beam computed tomography (CBCT) and intraoral scanners (IOS) acquisition methods.
Methods: Twelve participants (mean-age: 38 ± 5 years) requiring full mouth rehabilitation were included in this crossover trial. Two sets of identical CAD-CAM provisional restorations, differing only in the method of data acquisition (A: CBCT, B: IOS), were fabricated.

Chlorhexidine (CHX) is a gold standard therapeutic agent against clinical oral pathogens. However, its oral use is limited due to unpleasant taste, alteration in taste buds, staining of teeth and mucous membranes. Therefore, CHX-loaded PLGA microneedles (MNs) were fabricated for local and controlled release in the oral cavity, using a casting mold method.

Introduction: This study aimed to assess the effect of cavity designs on instrumentation, obturation and fracture resistance for mandibular first premolars with Vertucci V canal.
Methods: Mandibular first premolars with Vertucci V canal were scanned with micro-CT. 20 teeth with moderately curved canal were prepared with conservative endodontic cavity (CEC/M) or traditional endodontic cavity (TEC/M), and 30 with severely curved canal were prepared with CEC (CEC/S), modified CEC (MCEC/S) or TEC (TEC/S).

Purpose: The present study investigated the effect of unpleasant salty or bitter tastes on cycling sprint performance and knee-extensor force characteristics in different fatigue states.
Methods: Following a familiarization session, 11 trained male cyclists completed 3 experimental trials (salty, bitter, and water) in a randomized crossover order. In each trial, participants cycled at 85% of the respiratory compensation point for 45 minutes and then, after a 5-minute rest, completed a 1-minute sprint.
