Laser Therapy/Electrosurgery Diode laser–assisted management of intraoral soft tissue overgrowth: a case seriesMonika PalFull Article (PDF)
Rajeshwari H. R.
A case series describes the use of a 980-nm diode laser to treat soft tissue enlargement of the oral cavity. The results suggest that a 980-nm diode laser may be advantageous for treating benign proliferative lesions of the oral mucosa with negligible adverse sequelae.

Basic Science Comparison of the effects of whitening and conventional toothpastes on the wear rate of a composite resinMehrdad GholiporFull Article (PDF)
An in vitro study compared 3 whitening toothpastes and a nonwhitening daily toothpaste to determine their effects on the abrasive wear of a composite resin. Two bleaching toothpaste brands caused significantly more abrasion of the composite specimens than the control toothpaste.

A case-control study evaluated the association between denture-related oral mucosal lesions and Alzheimer disease (AD). Logistic regression analysis showed a higher prevalence of AD among individuals aged ≥ 80 years, those who were illiterate, users of tobacco, and patients with a slower gait, but the results suggested that AD is not a risk factor for denture-related oral mucosal lesions.

Basic Science The influence of LED irradiance on the degree of conversion of resin luting agents under translucent zirconiaRafaella GraselFull Article (PDF)
Gildo C. Santos, Jr
Maria Jacinta Santos
This study aimed to evaluate the effect of different LED irradiance levels on the degree of conversion (DC) of dual-cured resin luting agents photocured through a high-translucency zirconia disc. The interpositioned zirconia did not reduce the DC of the tested luting agents compared to direct irradiation. The influence of the LED irradiance level on the DC was material dependent.

Basic Science Retention of flowable composite resins in comparison to pit and fissure sealants: a systematic review and meta-analysisSaumya TanejaFull Article (PDF)
A meta-analysis of studies comparing the 12- and 24-month retention rates of flowable composite resins and conventional pit and fissure sealants found that flowable composite resins showed better outcomes at 12 months. There was no statistically significant difference in retention rates at 24 months.

This article presents the first reported case of a pyogenic granuloma affecting the tongue of an adult with Down syndrome. After 2 recurrences following lesion excision, the patient was provided with a silicone mouthguard to prevent the precipitating localized trauma, and no further recurrences were observed after 18 months.

A 5-year-old girl with amelogenesis imperfecta received applications of cyanoacrylate on the immature permanent first molars as a desensitizing agent after sodium fluoride varnish applications were unsuccessful in relieving sensitivity. Cyanoacrylate applications resulted in reductions in the patient’s frequency of complaints of pain and difficulty in drinking and eating.

Sleep Apnea & Appliance Therapy Vertical dimension in dental sleep medicine oral appliance therapyJerry C. HuFull Article (PDF)
John C. Comisi
This pilot study evaluated the effect of including the vertical dimension, as assessed using pharyngometry, in the occlusal registration for oral appliance therapy. In 26 patients who completed the study, the mean apnea-hypopnea index (AHI) was 20.7 before therapy and 7.8 after therapy. Within the limitations of this study, the pharyngometer-established occlusal position was effective in lowering AHI without the need for appliance titration procedures.

Periodontics Effect of cervical margin relocation technique with composite resin on the marginal integrity of a ceramic onlay: a case reportMuneera Abdulaziz AlhassanFull Article (PDF)
Salwa Omar Bajunaid
Treatment of a large proximal carious lesion that extends below the cementoenamel junction is challenging. Large defects usually require replacement with indirect restorations (inlays, onlays, or crowns). However, when the gingival cavity margins are deep, procedures such as isolation of the operative field, proper cavity preparation, successful impression-making, and adhesive luting may be hindered unless soft gingival or hard bony tissues are removed to expose the cavity margin. The present case report describes the clinical application of a conservative cervical margin relocation technique for treating deep cavity margins. A patient presented with large distal carious lesions and necrotic pulps in both the maxillary and mandibular right first molars, which were diagnosed with symptomatic apical periodontitis. After root canal treatment of both teeth, the maxillary molar underwent a crown-lengthening surgical procedure and subsequent placement of a zirconia crown. In the mandibular molar, the cervical margin was relocated by placing a composite resin base at the proximal gingival cavity margins under meticulous isolation of the operative field. The tooth was restored with a composite core build-up and bonded ceramic onlay. The satisfactory outcome suggested a promising prognosis for the oral health of the patient.
