Partial Dentures
Single appointment interim partial denture for a patient with a self-maintained provisional
M. Rammal, DDS
C. Alfonso, DDS, MS, FACP
2014 July/Aug; 62(4):20.
This article presents a case involving a patient with an aging self-maintained provisional. A modified technique for interim prosthesis fabrication was utilized that involves decoronation of the teeth prior to extraction, so that the anatomical soft tissues can be visualized. This technique is a cost-effective, expeditious approach to restore function in a single appointment.

2014 July/Aug; 62(4):24.
This article analyzes the results of a survey designed to assess self-reported oral health status, perceptions, and access to care between the Hispanic population and the general population of the United States. The data indicate disparities do exist between the Hispanic and the general populations. They highlight the need for new policies and programs—from organized dentistry to individual practices—that address the needs of the growing Hispanic population.

This intraoral imaging study compared effective doses from circular and rectangular collimator modalities. Adult and child full mouth series were exposed using a circular collimator, a universal rectangular collimator, and an enhanced rectangular collimator on phantoms. Rectangular collimation significantly reduced doses for adult exposures. In child exposures, only the universal rectangular collimator achieved significant dose reduction.

2014 July/Aug; 62(4):41.
This study compared levels of the 2 crevicular enzymes—myeloperoxidase (MPO) and alkaline phosphatase (ALP)—in peri-implant sulcus fluid around platform-switched implants (implant group) vs the 2 enzymes’ levels in gingival crevicular fluid around contralateral natural teeth (control group). The results from the implant group showed a statistically significant reduction in MPO levels from the first to the third collection, and a statistically significant increase in ALP levels over the 3-month post-treatment period, as compared to the control group.

The relationship between frenulum length and malocclusion
Arash Azizi, DDS, MSc
Sona Moosavi, DDS
Abdolreza Jamilian, DDS, MSc
2014 July/Aug; 62(4):66.
In this study, patients awaiting orthodontics were divided into 3 groups (n = 50) based on their lingual frenulum ANB (Point A, nasion, point B) angle: Group 1 (ANB angle = 0-4 degrees), Group 2 (ANB angle > 4 degrees), and Group 3 (ANB angle < 0 degrees). The mean frenulum length for Group 1 subjects was 11.4 (± 3.0) mm, compared to 9.5 (± 3.5) mm for Group 2 subjects, and 14 (± 3.0) for Group 3 subjects. These differences were statistically significant (P < 0.001). Maximum mouth opening was significantly greater for the Group 3 subjects. (P < 0.001).

Anesthesia and Pain Control
Comparative evaluation of transdermal diclofenac patch and oral diclofenac as an analgesic modality following root coverage procedures

Diclofenac sodium is a nonsteroidal anti-inflammatory drug, and is effective in the management of pain following periodontal surgery. However, oral administration of diclofenac can lead to gastrointestinal complications. A diclofenac transdermal patch was effective in postoperative pain control following root coverage procedures, and pain tolerance was higher when compared to orally administered diclofenac.

2014 July/Aug; 62(4):e5.
Desquamative gingivitis (DG) is a clinical term used to describe red, painful, glazed, friable gingiva. This case is unique in that it involves oral lichen planus and chronic DG, which may be secondary to plaque or a manifestation of the oral lichen planus. Intraoral examination and biopsy reports revealed features of chronic DG and oral reticular lichen planus.

This study evaluated the eruption sequence of the permanent maxillary canine in patients to determine if it follows the previously established normal pattern: first premolar, second premolar, and canine. Based on the results obtained in this study, the eruption sequence of the permanent maxillary canine followed the historical normal pattern for the majority of patients in this population. The difference in eruption sequence for males versus females was not significant.

This study evaluated how preheating affected the properties of a silorane-based composite restorative material and 4 methacrylate-based composites. With the exception of a flowable composite, significant reductions in viscosity were found between all preheated and room temperature composites, with no significant difference in other properties. In general, preheating the composites decreased viscosity, but did not affect compressive strength, depth of cure, or shrinkage per composite type.

This in vitro study evaluated the efficacy of calcium hydroxide Ca(OH)2 pastes prepared with different vehicles in preventing bacterial infiltration in teeth exposed to human saliva. Root canals were instrumented and filled with Ca(OH)2 paste prepared with different vehicles: saline solution, polyethylene glycol, or polyethylene glycol and camphorated paramonochlorophenol. Based on the results, calcium hydroxide paste prepared with saline solution was the most effective.

This is a case report of a 58-year-old man receiving immunosuppressive therapy 9 years after undergoing a kidney transplant. Earlier incisional biopsies had resulted in diagnoses of actinic cheilosis. However, the last biopsy showed results compatible with squamous cell carcinoma, and oncologic surgery was performed. Frequent dental follow-up visits allowed for the early diagnosis, proper treatment, and an improved prognosis.

This in vitro study investigated 4 products (containing calcium, phosphate, and/or fluoride) and their ability to reharden enamel softened by hydrochloric acid as compared to hardening with saliva alone. For all groups, Vickers hardness decreased significantly after immersion in hydrochloric acid. Fluoride in combination with casein phosphopeptide amorphous calcium phosphate was the most effective treatment for enamel hardness recovery.

2014 July/Aug; 62(4):e34.
This study sought to investigate how pretreatment intracanal placement of calcium hydroxide (Ca(OH)2) affected the sealing ability of mineral trioxide aggregate (MTA) plugs in simulated open apices. The specimens in Group 1 were pretreated using a Ca(OH)2 medicament, while the samples in Group 2 received no medicament. One week later, a 5 mm apical plug of MTA was applied into the canals. Group 1 had a significantly higher frequency of apical leakage than Group 2 (P < 0.05).

This study sought to evaluate the contamination level of absorbent paper points used routinely in dental clinical practice. Sixty absorbent paper points were collected and separated into 3 groups: 20 paper points from sealed commercial packages, 20 paper points from open commercial packages in use for 30 days, and 20 paper points from a sealed commercial package that were manipulated by the operator. Inadequate manipulation of paper points by the operator caused contamination. In addition, the bacterial growth found in absorbent paper points that were still in their commercial package indicates the importance of sterilization before the paper points are used in clinical practice.
