Host-bacterial interplay in periodontal disease

A literature search was performed using MEDLINE (PubMed) and other electronic basis from 1991 to 2014. Search included books and journals based on the systematic and critical reviews, in vitro and in vivo clinical studies on molecular basis of host microbial interactions. Clearly, an understanding of the host susceptibility factor in addition to microbial factors by elucidating the molecular basis offers opportunity for therapeutic manipulation of advancing periodontal destruction. One of the hallmarks of pathogenesis is the ability of pathogenic organisms to invade surrounding tissues and to evade the host defence. This paper focuses the general overview of molecular mechanisms involved in the microbiota and host response to bacterial inimical behavior in periodontics

Peripheral osteoma of the hard palate

Osteomas are benign slow growing, osteogenic lesions which may arise from proliferation of either cancellous or compact bone. They are usually sessile tumours composed of dense sclerotic, well formed bone projecting out from the cortical surface, most often of the skull and facial bones. This paper reports a case of a peripheral osteoma in the hard palate of a 45-year-old man, which was treated by periodontal flap surgery with surgical excision of the bony lesion. Peripheral osteomas of jaw bone are uncommon and usually associated with Gardner's syndrome. Histological examination confirmed the clinical impression of a peripheral osteoma. Patient was reviewed after one year and was asymptomatic with no recurrence of the lesion

Clinical Assessment of the Effects of Low-Level Laser Therapy on Coronally Advanced Flap Procedure in the Management of Isolated Gingival Recession

The aim of this randomized, controlled split-mouth clinical trial was to assess the effect of LLLT on wound healing after modified coronally advanced flap (MCAF) procedure for treatment of isolated recession-type defects. Fifteen patients with isolated bilaterally symmetrical gingival recessions (Miller’s Class I or Class II, or a combination of both) were enrolled in this study. After a modified, coronally advanced flap technique was implemented, a diode laser (810 nm) with a power of 120 mW irradiated the inner surface of the flap and the outer surface of the flap (low-level laser therapy—LLLT) after suturing for 5 min. This was repeated for the following four consecutive days. Descriptive statistics, a Kruskal–Wallis test and a Mann–Whitney test were performed to analyze the data. A p-value of less than 0.05 was considered statistically significant. The mean recession depth decreased from 3.33 ± 0.9 mm (baseline) to 0.2 ± 0.3 mm (3 months) and 0.4 ± 0.2 mm (6 months) in the test group. The mean recession width decreased from 3.8 ± 0.7 mm (baseline) to 0.2 ± 0.3 mm (3 months) and 0.5 ± 0.3 mm (6 months) in the test group. Due to minimal pain and discomfort, patient acceptability was quite high
