This article reviews the basic clinical techniques of performing a maxillary molar endodontic access opening, starting from the initial access opening into the pulp chamber, to the point where a size #10 file has been advanced to the apices of all three or four (or more) canals. The article explains how the use of the dental surgical operating microscope or microscope-level loupes magnification of ×6-8 or greater, combined with head-mounted or coaxial illumination, improve the ability of a dentist to identify microscopic root canal orifices, which facilitates the efficient creation of conservative access openings with adequate straight-line access in maxillary molars...

Nasoalveolar molding (NAM) can be done effectively to reshape the nasal cartilage and mold the maxillary dentoalveolar arch before surgical cleft lip repair and primary rhinoplasty. Presurgical NAM helps as an adjunct procedure to enhance the esthetic and functional outcome of the surgical procedures. We have developed a modified NAM device to suit to the needs of the patients coming from distant places for the treatment. This device helps in reducing the number of frequent visits the patient needs to take to the craniofacial center...

The total removal of a lesion via excisional biopsy causes gingival recession, resulting in dentin hypersensitivity and esthetical problems. In this case report, a gingival recession defect resulting from an excisional biopsy was treated with a free gingival grafting procedure performed during the same appointment, and its 12-year follow-up was presented. A 44-year-old female patient was presented to our clinic with a firm, pedunculated, red gingival enlargement located on the labial surface of lower incisors...

This case report demonstrates the full-mouth rehabilitation of a 45-year-old male patient with severe deep-bite by increasing vertical dimension. The technique of anterior maxillary osteotomy performed in the present situation has been found to be effective, requiring anterior and inferior repositioning of the anterior maxilla to provide an esthetic and functional implant supported fixed prosthesis. Four months after surgery, the fixation system was removed, and 6 dental implants were placed. The anterior and inferior movements of the segment allowed for natural tooth anatomy and size in the definitive implant supported partial fixed prosthesis...

OBJECTIVE: Green tea extract (GTE) was shown to be effective in preserving periodontal ligament fibroblasts (PDLFs) of avulsed teeth. This study aimed at determining the potential of GTE in preserving the viability of PDLFs comparing with different storage media. MATERIALS AND METHODS: Periodontal ligament cells were obtained from freshly extracted healthy impacted third molars and cultured in Dulbecco's Modified Eagle Medium (DMEM). Cell viability was determined by storing the cells in seven media; DMEM, tap water, Hank's balanced salt solution (HBSS), whole milk, hypotonic sucrose solution, GTE, and GTE + sucrose for 1, 2, 4, and 24 h at 37°C using tetrazolium salt-based colorimetric (3-[4, 5-dimethylthiazol-2-yl]-2, 5-diphenyl tetrazolium bromide) assay...

OBJECTIVE: The aim of the this study was to evaluate the perception of smile esthetics and alterations in cases of gingival plastic surgery for correction of a gummy smile, by means of alterations in smile photograph among dentistry degree students. MATERIALS AND METHODS: A frontal smile photograph of a 40-year-old woman having normal occlusion was used with diverse compositions of gingival exposure level and crown length of maxillary teeth. The eight photographs were evaluated by 216 dentistry students in five class groups (1(st), 2(nd), 3(rd), 4(th) and 5(th) classes)...

OBJECTIVE: There is no data specific to the Qatari population on the prevalence and distribution of hyperdontia. The aim of this study was to investigate the prevalence and distribution of hyperdontia in the permanent teeth among a group of Qatari sample and to compare the present results with findings from other populations. MATERIALS AND METHODS: Records of 1269 Qatari patients (674 females; mean age 11.8 ± 2.3 and 595 males; mean age 11.4 ± 2.2 years) which included panoramic radiographs were examined to identify hyperdontia in the permanent dentition...

OBJECTIVE: To compare the effectiveness of various caries removal techniques in mandibular primary molars using Smart Burs, atraumatic restorative technique (ART) (mechanical caries removal) and Carie-care (chemomechanical caries removal [CMCR]) among primary school children in clinical and community-based settings. MATERIALS AND METHODS: A total of 80 carious primary mandibular molars were selected for the study from the dental clinic and community.

OBJECTIVE: Although sucrose is considered the most cariogenic carbohydrate in the human diet, the question of how many exposures are needed to induce damage on the hard dental tissues remains unclear. To approach this question, different frequencies of daily sucrose exposure were tested on a relevant biological caries model. MATERIALS AND METHODS: Biofilms of the Streptococcus mutans were formed on enamel slabs and exposed to cariogenic challenges with 10% sucrose for 5 min at 0, 1, 3, 5, 8, or 10 times per day...
