Does Vitamin D3 Have an Impact on Clinical and Biochemical Parameters Related to Third Molar Surgery

Mannitol Reduces Pain and Trismus After Impacted Mandibular Third Molar Surgery

BACKGROUND

The removal of the lower third molar is a routine procedure in oral surgery, yet it often leads to postoperative side effects, particularly inflammation. Despite various interventions explored in prior studies, there is still a need for effective strategies, such as anti-inflammatory substances, to address postoperative side effects.

PURPOSE

The purpose of this study is to answer the following clinical question: Does the local injection of 0.9 M mannitol reduce postoperative pain, trismus, and swelling in patients undergoing bilateral symmetrically impacted mandibular third molar extraction?

STUDY DESIGN, SETTING, SAMPLE

This prospective, single-blind, split-mouth study at Hamadan Dental School involved 30 patients with bilateral symmetrically impacted mandibular third molars. Inclusion criteria were: no current medication, no anesthesia allergies, bilateral symmetrically impacted mandibular third molars, non-smokers, and the absence of systemic diseases. Exclusion criteria were: poor oral hygiene, alcohol/cigarette use, drug consumption, diabetes, systemic/gastrointestinal disorders, infection at the surgical site, lack of patient cooperation, and mannitol/anesthetic allergy.

PREDICTOR/EXPOSURE/INDEPENDENT VARIABLE

The predictor variable was therapeutic injection, and it was grouped into two categories, 0.9 M mannitol solution or distilled water.

MAIN OUTCOME VARIABLE

The primary outcome variable was pain. Secondary outcomes are trismus, swelling, patient satisfaction, and analgesic consumption.

COVARIATES

Covariates included demographic information and operative details.

ANALYSES

Statistical analyses included repeated measures and paired t-tests with a significance level set at P < .05.

RESULTS

The study comprised 30 participants (mean age: 22.6 ± 3.59 years; 6 men, 24 women). In the test group, pain intensity significantly decreased from 5.30 on surgery day to 0.00, with subsequent values of 2.97, 1.30, 0.40, 0.17, and 0.03. The control group also decreased from 7.68 to 0.00, with values of 4.73, 2.67, 0.97, 0.23, and 0.07. The difference was statistically significant (P < .001). No significant swelling differences at T1, T3, T5, and T7 (P > .05). The intervention group had improved maximum mouth opening at T1, T3, T5, and T7 (P = .011) compared to the control group.

CONCLUSION AND RELEVANCE

Mannitol infiltration significantly reduces postoperative pain and trismus in impacted third molar surgery. This finding underscores the potential for improved patient comfort and recovery in this context.

Three-dimensional facial swelling evaluation of piezo-electric vs conventional drilling bur surgery of impacted lower third molar: a randomized clinical trial

BACKGROUND

Among the post-surgical complications of lower wisdom teeth surgery, swelling is considered by patients one of the most impairing, with both social and biological influences and impacting patients' quality of life. Aim of the study was to evaluate the swelling following the osteotomy when performed with drilling burs versus piezo-electric instruments in the mandibular impacted third molar extraction, using a facial reconstruction software.

MATERIALS AND METHODS

A randomized, split-mouth, single-blind study was conducted on patients, ranging between 18 and 40 years of age, requiring lower third molars extraction and referred at the Oral Surgery Unit of the School of Dentistry of the University of Messina. Twenty-two patients were recruited during an 8 months period according to the following criteria: good general health conditions; bilateral, symmetrical, impacted third molars; no use of medication that would influence or alter wound healing; no temporomandibular joint disorder history; no smoking. All patients underwent bilateral surgical removal. For each patient, a facial scan was obtained prior to the surgical procedures. The two extractions were conducted performing, in a randomized way, osteotomy with rotatory burs or use of piezo surgical instruments. Facial scans were repeated at 3 and 7 days after the surgical procedures. Volumetric differences were calculated via superimposition using a dedicated software. The data obtained were processed using paired t-test.

RESULTS

The results obtained from our study showed no significant differences between two groups regarding post-operative swelling. To the best of our knowledge, this study represents the first experience of using an objective method that can be reproducible on the collection of patients' clinical parameters.

CONCLUSIONS

The 3D digital analysis, in the evaluation of facial swelling, is a technique of simple application, objective, reproducible, reliable, decreasing the variables of error. Based on these data, it is possible to conclude that piezo surgery is a safe way for performing the osteotomies during third molar surgery. However, regarding the post-operative swelling, it does not show an advantage over classical rotary instruments.

Bone health in Duchenne muscular dystrophy: clinical and biochemical correlates

PURPOSE

An increased fracture risk is commonly reported in Duchenne muscular dystrophy (DMD). Our aim was to investigate bone mineral density (BMD) and bone turnover, including sclerostin, and their association with markers of cardiac and respiratory performance in a cohort of DMD subjects.

METHODS

In this single center, cross sectional observational study, lumbar spine (LS) BMD Z-scores, C-terminal telopeptide of procollagen type I (CTX) and osteocalcin (BGP), as bone resorption and formation markers, respectively, and sclerostin were assessed. Left ventricular ejection fraction (LVEF) and forced vital capacity (FVC) were evaluated. Clinical prevalent fractures were also recorded.

RESULTS

Thirty-one patients [median age = 14 (12-21.5) years] were studied. Ambulant subjects had higher LS BMD Z-scores compared with non-ambulant ones and subjects with prevalent clinical fractures [n = 9 (29%)] showed lower LS BMD Z-scores compared with subjects without fractures. LS BMD Z-scores were positively correlated with FVC (r = 0.50; p = 0.01), but not with glucocorticoid use, and FVC was positively associated with BGP (r = 0.55; p = 0.02). In non-ambulant subjects, LS BMD Z-scores were associated with BMI (r = 0.54; p = 0.02) and sclerostin was associated with age (r = 0.44; p = 0.05). Age, BMI, FVC and sclerostin were independently associated with LS BMD Z-score in a stepwise multiple regression analysis. Older age, lower BMI, FVC and sclerostin were associated with lower LS BMD Z-scores.

CONCLUSION

In a cohort of DMD patients, our data confirm low LS BMD Z-scores, mainly in non-ambulant subjects and irrespective of the glucocorticoid use, and suggest that FVC and sclerostin are independently associated with LS BMD Z-scores.

Evaluation of Vitamin D (25OHD), Bone Alkaline Phosphatase (BALP), Serum Calcium, Serum Phosphorus, Ionized Calcium in Patients with Mandibular Third Molar Impaction. An Observational Study

The aim of this study was to evaluate the levels of vitamin D (25OHD) and other bone biomarkers in patients with third molar impaction (TMI). Thirty males and 30 females with unilateral or bilateral impacted mandibular third molar, and 15 males and 15 females as a control group (CG) were recruited. Rx-OPT was used to evaluate dental position and Pederson index to measure the difficulty of the intervention. Bone biomarkers were measured through blood venous sample in TMI group and CG. Mann-Whitney test, Pearson’s correlation coefficient, linear regression model were used to compare the different parameters in the two groups. 25OHD showed lower values in TMI group than in CG (p < 0.05) with values significantly lower in bilateral impaction (p < 0.05). Pearson’s coefficient for 25OHD presented a negative correlation with the Pederson index (ρ = −0.75). Bone alkaline phosphatase (BALP) showed significantly lower dosage in TMI group than CG (p = 0.02), Pearson’s coefficient for BALP presented a negative correlation with the Pederson index. Serum calcium, serum phosphorus, ionized calcium levels in TMI and CG groups were similar and Mann-Whitney test did not significantly differ between TMI and CG. TMI could be a sign of vitamin D deficiency and of low BALP levels that should be investigated.

Vitamin D, Bone Metabolism, and Fracture Risk in Polycystic Ovary Syndrome

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder among premenopausal women. PCOS may have reproductive, metabolic, cardiovascular, and psychological implications. Vitamin D deficit is often encountered in PCOS women and may contribute to the pathophysiology of this disorder. As of the key role of vitamin D in bone and mineral metabolism, and because the vitamin D status appears to be closely linked with the PCOS manifestations including insulin resistance, obesity, ovulatory and menstrual irregularities, oxidative stress and PTH elevation, hypovitaminosis D may directly and indirectly via the different facets of PCOS impair bone health in these women. Although limited data are available on life-long fracture risk in women with PCOS, the importance of preserving bone health in youth and adults to prevent osteoporosis and related fractures is also recognized in PCOS women. Evidence of the association between vitamin D and the clinical hallmarks of PCOS are summarized and discussed. Vitamin D arises as a cornerstone in women with PCOS and contributes to the pathophysiological link between PCOS and bone metabolism.

Antibiotic Prophylaxis on Third Molar Extraction: Systematic Review of Recent Data

The aim of this paper was to highlight the most widely antibiotic protocols applied to the dental field, especially in the surgical treatment of impacted wisdom teeth. Once these protocols were screened, all the possible advantages or disadvantages for each drug and each posology were recorded in this review. In recent years, the need to use these protocols has been debated in the literature. The data obtained by this review underlined how antibiotic protocols applied to oral surgery treatments only included surgeries performed on patients who did not present other systemic pathologies. The first literature review obtained 140 results, and then after the application of the inclusion criteria, 12 papers were selected. The results showed that the most commonly used protocol involved the use of penicillin and clavulanate, obtaining safe clinical and prophylactic results in the management of infections. This widely used protocol seems to guarantee high predictability and safety. The presented review highlights the current possibility of antibiotic resistance affecting patients due to drug misuse. Further clinical studies are required to state specific guidelines; however, oral surgeons involved in third molar surgery should evaluate the local and general health conditions of the patients before suggesting any drug measures for patients.

Third Molar Eruption and Hardware Fungal Infection Following Treatment of Mandibular Angle Fracture

Appropriate management of lower 3rd molars is crucial to successful treatment of mandibular angle fractures. A unique case of a patient who presented for initial management of a left mandibular angle fracture with an unerupted lower 3rd molar was discussed in this study. After treatment with open reduction and internal fixation of the fracture, the lower 3rd molar erupted and the patient subsequently developed fungal osteomyelitis and hardware failure. This was successfully treated with hardware removal, maxillomandibular fixation, and combined use of an intravenous antibiotic and oral antifungal.

Impact of electro-neuro-feedback on postoperative outcome of impacted lower third molar surgery

Objective

The purpose of this study was to evaluate the impact of a treatment with electro-neuro-feedback (ENF), a portable transcutaneous electrical nerve stimulation (TENS) device, on the clinical outcome and inflammatory biochemical parameters related to the impacted lower third molar surgery.

Materials and Methods

A randomized, split-mouth, and single-blind study was conducted on 32 patients requiring lower third molars extractions and referred to the Oral Surgery Unit of the School of Dentistry of the University of Messina. Every patient underwent surgical removal of both lower third molars. The first extraction included a placebo (electrodes placement with turned-off device) treatment following the surgery, while the second had the ENF used next to the avulsion and the following days. Clinical parameters were collected 4 days before, immediately after, 2, 4, and 7 days after the surgical procedure. Biochemical parameters were obtained 1 day before the surgical removal and 7 days after. Data were processed using Wilcoxon-Mann-Whitney test, with significance being set at P < 0.05.

Results

Clinical outcome parameters showed a significant improvement after the ENF treatment, while considered inflammatory markers expressed different patterns.

Conclusions

ENF, a reliable portable TENS device, has demonstrated to be a useful tool in the managing of the postsurgical phases, reducing edema, pain, and consequent pain-killers consumption.

Pain in Osteoporosis: From Pathophysiology to Therapeutic Approach

The high worldwide prevalence of osteoporosis means it is considered a serious public health concern, possibly leading to physical disability and an increased mortality rate. Although osteoporosis is known as a silent disease affecting aging populations, its primary symptom remains pain. Acute pain is reported by patients with osteoporosis-related fractures, but chronic pain, mainly back pain, is also a characteristic of severe osteoporosis. Pain is associated not only with fractures but also with bodily changes in patients with osteoporosis that may include sensory, affective, and cognitive aspects. Chronic pain leads to progressive loss of independence and the need for long-term care, especially in the elderly. Pain prevention is linked to the appropriate treatment of osteoporosis, and pain management in patients with osteoporosis requires a multidimensional approach to preserve and improve quality of life. Our aim was to review and discuss the main causes of pain in patients with osteoporosis and suggest possible strategies for its management and prevention.
